The study aimed to investigate the influence of chitosan particles loaded with sodium sulfate on the structure and properties of the gelatin films by using gelatin as the film-forming matrix and adding chitosan particles loaded with sodium sulfate to prepare composite gelatin films. The thickness, hydration properties, barrier properties, mechanical properties, optical properties, thermal stability and oxidation resistance of the gelatin films were measured, and its structure was characterized. The results showed that the addition of chitosan particles loaded with sodium sulfate significantly decreased the thickness (P<0.05), significantly increased the swelling rate (P<0.05), decreased the dissolution rate from 79.41% to 18.21%, increased the tensile strength from 79.10 MPa to 128.96 MPa, increased the opacity from 3.75 to 6.77, improved the thermal stability, and increased the DPPH radical scavenging capacity from 14.41% to 65.05% of the gelatin films. However, there were no significant changes in the water vapor permeability and elongation at break of the gelatin films. In addition, there was a high compatibility between chitosan particles loaded with sodium sulfate and gelatin molecules, and the addition of chitosan particles loaded with sodium sulfate changed the structure of gelatin films. In conclusion, the incorporation of chitosan particles loaded with sodium sulfate can change the structure of gelatin films to some extent and improve the properties of gelatin films. This study provides theoretical guidance and data reference for the preparation and application of antioxidant composite gelatin films. [ABSTRACT FROM AUTHOR]

The effect of the thermal composite fluid remaining in the reservoirs on the rheological properties of the plugging agent particle solution is still unclear at the late thermal composite development stage of the heavy oil reservoirs. Therefore， it limits the application of particle solutions in this stage. For this， based on the rheological theoretical model and viscosity-concentration formula， a viscosity-concentration relationship that can accurately describe the SiO2 + polymer dispersion system was preferably selected by combining the viscosity-concentration change of particle solutions. The effects of different factors on the rheological properties of the SiO2 + polymer dispersion system and the mechanism were investigated by using a rheometer， a Zeta potential analyzer， and a scanning electron microscope. The results show that the viscosity-concentration relationship of the SiO2 + polymer dispersion system is in accordance with the Krieger and Dougherty viscosity-concentration models. The viscosity of the SiO2 + polymer dispersion system decreases with increasing temperature or mineralization. The viscosity of the SiO2 + polymer dispersion system in-creases with increasing particle concentration or pH. The difference in viscosity between SiO2 + polymer dispersion systems with anionic and nonionic surfactants is not significant， while the viscosity of SiO2 + polymer dispersion system with cationic surfactants is significantly greater than that of the remaining two solutions. The viscosity of the particle solutions with different types of surfactants decreases as the pH decreases. Therefore， it is important to select a suitable particle solution to provide a theoretical basis for the application of SiO2 + polymer dispersion system in the late thermal composite development stage of thick oil reservoirs.

In order to explore the dissolution effect and properties of tobacco leaf and tobacco stem particles, and to achieve the maximum retention of effective substances in the production of paper-making process reconstituted tobacco, the effects of dissolution conditions on the dissolution effect of tobacco leaf and tobacco stem particles were investigated, and the changes of components, thermal weight loss behavior, and aroma components of tobacco leaf and tobacco stem particles before and after dissolution were compared and analyzed. The results showed that under the conditions of 40~80 mesh, 0~10 min, 20~40 °C, and low addition ratio, the dissolution rate of particles was the fastest. The components of water-soluble sugars, total alkaloids, and chlorine of tobacco leaves and stalk particles showed a decreasing trend after dissolution, which deceased with the increasing dissolution time. In addition, there were some differences in the amount of each dissolved component. Before and after dissolution, the tobacco leaf and tobacco stem particles experienced four and five weightlessness stages with close temperature range, and the temperature range of the second stage of tobacco leaf roughly included the second and third stages of tobacco stem particles, and the residual mass of each stage was lower than that of tobacco stem, and the components and thermal decomposition process of tobacco stem were more complex than that of tobacco leaf. 69 and 71 kinds of aroma components were retrieved from tobacco leaf and tobacco stem particles before and after dissolution, respectively, and the total amount of aroma components in tobacco leaf particles was higher than that in tobacco stem particles. The most aroma components in tobacco leaf and tobacco stem particles were ketones, followed by aldehydes, alcohols, heterocycles, acids, and esters, while phenols were the least. The dissolution rate of each type of aroma components was also different. [ABSTRACT FROM AUTHOR]

The reason is that titanium dioxide has always been the best choice of photocatalyst materials. The relevant documents and published papers from international organizations and nations such as China, the World Health Organization, the European Union, the United States, and Canada were investigated, summarized and analyzed・ Titanium dioxide nanoparticles are so tiny that they can enter the lungs and induce cancer. That is, the harm of titanium dioxide particles entering the human body through breathing is due to its physical properties rather than chemical properties. In the process of research and production of litanium dioxide photocatalyst, the dust is an issue・ When titanium dioxide is used as photocatalyst, normally it is immobilized・ The immobilized photocatalyst is not relevant to dust. Therefore, it is not associat・ ed with titanium dioxide photocatalyst that EU cauterized litanium dioxide into category 2 carcinogens (inhalation). [ABSTRACT FROM AUTHOR]

Coarse-grained soil has widely been used for construction and geological bodies, such as hydraulics and civil engineering. It is critical to clarify the transformation under the impact of muddy water seepage for better engineering uses. In this study, a series of calculation formulas were derived for the seepage of coarse-grained soil in a circular tube under the action of muddy water. An apparatus of muddy water seepage was self-developed to systematically investigate the characteristics of seepage in the coarse-grained soil subjected to the muddy water. A comparison was also carried out to verify the variable equations of soil hydraulic gradient, permeability coefficient, seepage flow, and the filling rate of pores. In addition, a calculation formula was deduced to determine the effect of muddy water seepage in the circular pipe on the differential equation of the permeability and the permeability coefficient of the coarse-grained soil at each stage after the experiments. The results are as follows. The seepage process of muddy water in the coarse-grained soil was generally divided into three stages: the smooth migration stage of fine particles (Stage 1), the coexistence of pore blockage and migration (Stage 2), and the deposition on the top of the coarse-grained soil (Stage 3). There was a significant correlation among the concentration of muddy water, the water head on the hydraulic gradient, and the permeability coefficient of coarse-grained soil. Specifically, there was also a strong intensity in the migration of fine particles, clogging, and deposition with the increase of muddy water concentration and water head. Furthermore, the hydraulic gradient inside the soil column increased significantly, as the permeability coefficient gradually decreased. It was very likely to occur the blockage and siltation, due mainly to the greater inhomogeneity coefficient of the coarse-grained soil, and the less smooth channel available for the fine particles to migrate, particularly under the smaller internal porosity and the lower connectivity. As such, the overall lower permeability was obtained in the coarse-grained soil during this time. Alternatively, the water head greatly contributed to the early migration of fine particles. But, the water head resulted in a higher speed of internal obstruction and top deposition at the same time. More importantly, the distance was also reduced for the movement of fine particles downward, leading to the dramatically dropping rate of permeability coefficient. The reason was that the fine particles migrated downward over a short distance during the process. Additionally, an unfriendly surrounding occurred under the rise of the concentration, leading to less movement of minute particles. The atmosphere was also produced for the less friendly environment in the period of the particle movement. It infers that most pores in the coarse-grained soil were filled with the water to steadily diminish the room in the direction of a seepage channel. The steepest drop gradient was found between 0 and 5 cm, and then more gradually flattened out between 5 and 20 cm at the stages. Consequently, the movement rate of particles increased on the top layer of coarse-grained soil. The finding can offer the theoretical basis for engineering applications and the seepage of muddy water. In particular, the anti-seepage properties of coarse-grained soil can be subjected to the change under the impact of muddy water seepage. [ABSTRACT FROM AUTHOR]

Particles will be mixed in journal bearings during operation. In order to investigate the effect of particles on oil film characteristics of journal bearing, based on the theory of fluid lubrication, a mathematical model of the dynamic and static characteristics of hydrodynamic journal bearings considering particles was established. The governing equation was discretized by the finite volume method and the first-order upwind,the discretized equation was solved by SIMPLE algorithm, and the influence of particle content on the bearing capacity and friction of the oil film was analyzed. The dynamic mesh-spring smoothing technology was used to update the volume mesh after the journal moves to solve the dynamic characteristic coefficient of the bearing, and the influence of impurity particles on the dynamic characteristic coefficient was analyzed. Results show that the bearing capacity and friction of the oil film ascend at first and then become stable with the increase of particle content, indicating that the particles can improve the oil film bearing capacity to a certain extent, but also increase the friction. The temperature of the oil film is symmetrically distributed around the oil inlet, and the oil film temperature decreases first and then increases in the axial direction. After considering the effect of particles, the four stiffness coefficients of the oil film all decrease, while the oil film damping coefficients Cxx and Cxy decrease, and Cyx and Cyy increase.

An industrialized Recirculation Aquaculture System (RAS) has been widely used in an efficient, intensive, and environment-friendly way for modern aquaculture. A large amount of feed needs to be added to the system during the breeding process. Some solid residuals can be easily deposited at the bottom of the breeding pond, such as the uneaten feed and feces produced by fish. These residuals can then be decomposed and produce harmful substances to pollute the water body, while consuming the dissolved oxygen, if they cannot be discharged in time. As such, a great threat has been posed to the health of fish. Therefore, it is very necessary to effectively and timely remove these solid particles in the RAS tank. In this study, a solid-liquid-gas three-phase flow model was constructed to optimize the layout of inlet pipes in a RAS tank using Computational Fluid Dynamics (CFD) technology. A STAR-CCM+ software was also selected to systematically simulate the common layout angle of inlet pipe (θ=0° and 45°, θ was the deployment angle of inlet pipe), under different layout positions (d=0, 1/8r, 1/4r, 3/8r, and 1/2r, d was the distance between the jet pipe and the tank wall, r is the radius of the aquaculture tank). The error of cumulative removal efficiency at each monitoring time was less than 5 percentage point, indicating a high calculation accuracy in the numerical simulation, compared with the experimental. A systematic investigation was made to explore the layout influence of water inlet pipes in the circular RAS tank on the flow field distribution in the tank, as well as the removal efficiency of solid particles. The results show that the position of inlet pipes outstandingly determined the removal efficiency of solid particles. The lowest removal efficiency of solid particles was obtained, when the layout distance was set to be d=0 and θ=0° under the rapid circulation (low hydraulic retention time). Furthermore, the removal efficiency was much higher (>90%) with small difference in the rest of the layout distance. Consequently, the maximum removal efficiencies were achieved in 94.8% and 94.3%, respectively, where θ=45°, d=3/8r, and d =0, whereas, the lowest removal efficiency of solid particles was found, when the layout distance was set to be d=1/2r. Therefore, it can be recommended not to be close to the side wall of the breeding tank in practice, when the inlet pipe was arranged at an angle θ=0°. By contrast, it can be recommended not to be too far from the side wall of the breeding tank, when the layout angle of the inlet pipe θ=45°. Anyway, the optimal collection efficiencies of solid particles with the inlet pipe layout angle of 0 and 45° were achieved similarly to be 95.0% and 94.3%, respectively, when the inlet velocity was 0.46 m/s (large water circulation velocity). At this time, the layout distances of the inlet pipe were d=1/8r and d=0, respectively. The findings can provide a strong reference to optimize the layout distance of inlet pipes in an industrialized RAS tank, thereby improving the comprehensive performance of circulating water aquaculture.

In order to obtain the details of the moon dust particles dynamic trajectory on the moon, and reduce the damage of the moon dust particles to the aircraft and astronauts, a particle dynamic trajectory measurement method was proposed, based on the asynchronous delay method and the light field camera. During the long exposure time,the trajectory of the particles recorded was used to observe the particles motion state. This topic firstly used a common Charge Coupled Device(CCD) camera to build a two-dimensional measurement system for particle motion trajectory measurement. This method did not require complex image processing algorithms,and used simple superposition of images realized the particle motion trajectory measurement,the measurement system error is 0.28%. It lays the foundation for the three-dimensional measurement of particle trajectory by using the light field camera later.

Calcic vertisol is a typical kind of low-yield field with a total area of about 4 million hm2 in China. Calcareous concretion with particle size larger than 2 mm has been one of the representative characteristics of calcic vertisol. The limitation of soil available water is an important reason for crop failure in this region. Therefore, the curve of soil water retention dominates the estimation of available water content. However, most studies focused on the effects of calcareous concretion on soil water retention of calcic vertisol mainly under laboratory conditions. It is lacking that under field conditions. In this study, both field surveys and laboratory experiments were conducted to explore the effect of calcareous concretion distribution in 0-1 m soil profile on soil water retention. Firstly, the spatial distribution of calcareous concretion was investigated in the study plot with 150 m length, 50 m width, and 1 m depth. After then, soil profiles (0-1 m soil depth) were chosen to divide into 5 layers with a 20 cm interval. Disturbed and undisturbed soil samples were collected in each layer. Physicochemical properties were evaluated to measure the distribution of soil particle size, size and content of calcareous concretion, bulk densities of soil, and calcareous concretions. Meanwhile, the curves of soil water retention were determined using high speed centrifuge. A pressure plate method was conducted to measure water retention curves in calcareous concretion. The results showed that the mass contents of clay, silt, and sand were 30.56%-39.75%, 39.88%-45.34%, and 18.67%-24.45%, respectively, which belonged to silty clay soil in the classification standard of the United States Department of Agriculture (USDA). Clayey particles decreased, but sandy particles increased significantly with the increase of soil depth. Calcareous concretion was mainly distributed in the soil depth of >20-100 cm, where the content and size increased as soil depth increased. Calcareous concretions content in the surface soil (0-20 cm) was very low (with mass content 0.02%), where only a few calcareous concretions of 2-5 mm were discovered. The maximum content of calcareous concretion was detected at > 80-100 cm (up to 11.42%), where the calcareous concretion content was 8.04% in the size of >8-30 mm. Soil bulk density ranged from 1.23-1.61 g cm-3. The densities of calcareous concretions were 2.01, 2.21, and 2.23 g cm-3 with the size of 2-5 mm, >5-8 mm, and >8-30 mm, respectively. Soil bulk density increased along with the calcareous concretion content increasing. Water retention curves of soil and calcareous concretion were well fitted by the van Genuchten model, with the determination coefficient larger than 0.95. The saturated water content of surface soil (0-20 cm) was significantly higher than that of 20-100 cm soil. Nevertheless, the Gravitational-water content in the surface soil (0-20 cm) was much larger than that in the soil of > 20-100 cm, which was related to macropores formed during tillage. In the subsurface (>20-100 cm), soil gravitational-water content and available water-holding capacity increased with the increase of soil depth, but the field capacity and wilting point decreased. Calcareous concretion maintained a non-negligible amount of water, 0.25, 0.22, and 0.20 cm3 /cm3 in the particles with the size of 2-5 mm, >5-8 mm, and >8-30 mm, respectively. But the water-holding capacities of calcareous concretion were significantly lower than that of soil. The effects of calcareous concretion on water-holding capacity mainly occurred in the subsurface soil. Soil saturated water content, field capacity, and wilting point decreased with increasing calcareous concretion. Interestingly, calcareous concretion content was positively correlated with the soil sand content, but negatively correlated with the soil clay content. Calcareous concretion can bind soil particles together to prevent sand weathering, and thereby effectively improve soil texture. More calcareous concretion led to higher sand contents, and thus increased the available water-holding capacity in soil. This finding can provide a theoretical basis to accurately assess the soil water-holding capacity in calcic vertisol for precision irrigation and high crop productivity. [ABSTRACT FROM AUTHOR]

The depression effect of starch on fine hematite is poor during the reverse flotation of hematite. Flotation tests, EDL VO calculations, particle size analysis and SEM analysis were used to investigate the depression effect of starch on fine hematite with the assistance of magnetic seeding aggregation. The results showed that the depression effect of starch on hematite decreased with the decrease of hematite particle size. The addition of magnetite enhanced the depression effect, which became more obvious with the increase of magnetite particle size. The attraction between magnetite of different sizes and fine hematite leads to the aggregation of magnetite with hematite particles, and the larger the particle size of magnetite, the stronger the attraction is. The magnetic seeding aggregation increased the apparent particle size of fine hematite, thus strengthened the depression effect of starch on hematite. [ABSTRACT FROM AUTHOR]

There exists tough convergence, burden computation, and low efficiency for solution to partial difference equations using Velocity-Verlet or ODE algorithms analyzing characteristics of particle motion. The finite element software COMSOL Multiphysics 5. 3a, which could be used to solve Laplace equation quickly in AC/DC module when these reasonable boundaries were chosen, provides the precondition for calculating dielectrophoretic force. In terms of particle tracing module in COMSOL software, the particles experienced dielectrophoretic effect were simulated through the selection of both time step and range when dielectrophoretic, Stokes drag, repulsive, and buoyant forces were taken into the table of stress parameter in particle tracking module. The results illustrated that this approach is capable of simulating the motion of such particles exerted by dielectrophoresis effect, reducing the complexity of program and improving man-machine visualization of dynamic simulation, and are consistent with Velocity-Verlet or ODE algorithms.

The mixing and separating process of different-sized particles in a self-designed rotating drum were explored, where the glass beads were taken as particles. The power consumption of rotating drum under different operating parameters were measured. The results show that the particle separation is more evident when the drum is operated at high fill level, where the small particles surrounded by large particles are mostly observed. When the filling rate is low, it is unobvious for the particle separation of the similar size particles at different rotating speeds. The larger difference of the particle size, the more particle separation occurs. With the increasing rotational speed and fill level, the power consumption increases, while the power consumption is relatively less sensitive to the particle size ratio. [ABSTRACT FROM AUTHOR]

A type of agitation-resistant emulsified wax was prepared where the 58# semi-refined wax was used as raw material and the mixture of glycerin monostearate, peregal O-20 and PEG-100 stearate was used as the main emulsifier. The results showed that the optimized conditions for preparing the paraffin emulsion were as follows: The HLB value of the composite emulsifier was 10.8; the amount of the emulsifier was 15% of paraffin wax; the emulsifying temperature was 80 °C; the emulsifying time was 30 min. The viscosity of the emulsified wax thus obtained was 14.7 s (No.4 viscosity flow cup); the particle size was less than 50 nm; Zeta potential was 180 mV; the solid content was 43.7%. Rheological properties showed that the emulsion was pseudoplastic fluid. When the emulsion was stirred at 1 500 r/min for 4 h, the emulsion exhibited a viscosity of 12.4 s (i.e., the viscosity was not increased), a solid content of 41.2%, good static and centrifugal stabilities, no phase separation, and a dispersibility of grade one, and its good fluidity was maintained not less than 7 days.

Grinding machines are a main force in grinding work and various types of grinding machines have been developed and used. In today's industry, where particles need to be ground down to smaller size than ever before, utilization of bead mills, a type of agitated media mill, can be an effective grinding method. On the other hand, not enough study has been made on the bead mill because it is still new in the history of the grinding machine. In this study, grinding tests were thus conducted with a dry-type bead mill, using different sizes of beads. As a result, the distribution of particle diameters changed in a similar way, regardless of the bead size, as the grinding proceeded. Further, for all bead diameters, the relationship between specific energy and median diameter followed the same rule, which demonstrated that use of smaller beads increases energy efficiency in relative terms.

In order to improve the utilization rate of waste ceramics in concrete， ceramic concrete was prepared by using “C” substitution method (traditional equal mass substitution method)，“P” substitution method (substitute natural river sands with different particle sizes)， “D” substitution method (substitute natural river sands with particle sizes of 1.18， 2.36 and 4.75mm) and “X” substitution method (substitute natural river sands with particle sizes of 0.15， 0.3 and 0.6mm.) to replace natural fine aggregate according to different proportion (10%， 20%， 30%， 40%， 50%). 21 groups of concrete were designed， including 1 group of reference concrete， 5 groups of concrete prepared of “C”， “P”， “D” and “X” substitution method respectively. The water-binder ratio is 0.49， and the compressive strength test of concrete takes for 28 days. The results show that when the water-binder ratio is 0.49 and the ceramic fine aggregate content is less than 50%， the compressive strength of ceramic fine aggregate concrete and the reference concrete are of the same strength level， and all reach the strength level of C30. The optimal substitution rate is different for different ceramic fine aggregate substitution methods. Different substitution rates of ceramic fine aggregate correspond to different optimal substitution methods. [ABSTRACT FROM AUTHOR]
