With its high melting point, high density, excellent ductility, and high strength, Ta-W/Hf alloy has been considered a key material for future nuclear fusion reactors and weapons. Based on the first-principles method of density functional theory, Ta-W/Hf alloy models with different doping contents were constructed.The lattice constants, cohesive energies, elastic constants, elastic moduli, Poisson's ratios, Vickers hardnesses, densities of electronic states and other property parameters of Ta-W/Hf alloys were calculated, and the effects of W and Hf elements on the stability and mechanical properties of the Ta-W/Hf alloy were analysed. The results show that the lattice constant, elastic constant, bulk modulus, Young's modulus and shear modulus of Ta-W alloy increase with the increase of W content. However, the trend of the relevant property parameters of Ta-Hf alloys is opposite. Meanwhile,the results of cohesive energy and electron state density clarify that the stability of the Ta-W alloy increases with the increase of W, while the structural stability of Ta-Hf alloys decreases when Hf elements are added to Ta; but the addition of Hf has a significant effect on the change of anisotropy trend of Ta alloy, Furthermore, Hf can obviously improve the toughness of Ta alloy.

Using whole wheat flour as the main raw material, three kinds of 3D printed whole wheat cookies with different internal structures (4-hole, 9-hole and 16-hole) were designed with 3D printing technology, and the effects of internal structural design on the printing characteristics of materials, sensory quality, texture characteristics and digestive characteristics of products were investigated. The results showed that 4-hole structure whole wheat cookie batter provided the best printing fluency. The 16-hole structure 3D printing of whole wheat cookie dough exhibited the highest internal and apparent structure printing accuracy and the highest apparent structure stability after baking. The comprehensive sensory scores of 9-hole structure 3D printed whole wheat cookie ((90.00±1.25) points) were significantly higher than those of 4-hole structure 3D printed whole wheat cookie (73.00±2.63) points and 16-hole structure 3D printed whole wheat cookie (72.00±1.70) points (P<0.05). The hardness ((1 355.90±197.74) g) and brittleness ((1 152.50±49.67) g) of 16-hole structure 3D printed whole wheat cookies were lower (P<0.05), and the in vitro digestibility of starch (57.61%) and pasting degree ((35.11±1.83) %) were the lowest. In conclusion, the internal structure design with 16-hole was advantageous for producing 3D printed whole-wheat cookies with higher printing accuracy, better stability, superior sensory quality, lower digestibility and suitable for diabetic patients.

In order to improve the structural and chemical stability of Li10GeP2S12 (LGPS), a series of In-doped LGPS electrolytes, Li10InxGe1-0.75xP2S12 (x=0.1-0.5) (LGInPS), were prepared by high-energy mechanical ball milling combined with high-temperature sintering.SEM morphology observation and XRD physical phase analysis showed that with the In elemental participation increased, the density and crystallinity of LGInPS series electrolytes gradually increased and when x>0.3, the impurity content began to increase and the particle agglomeration phenomenon began to be serious. The structural analysis and electrochemical performance of LGInPS electrolytes with optimal In doping x=0.3 were tested and compared with LGPS, and the results showed that the electrochemical and structural stability of LGInPS improved when the In doping amount was x=0.3. In addition, the structural unit of the highly conductive phases in LGInPS was strengthened, the AC impedance reduced (69%), and the ionic conductivity increased (106%). [ABSTRACT FROM AUTHOR]

The nickel-rich layered cathode materials LiNixM1-xO2 （x>0.8，M=Co，Mn，Al，etc.） have become the most promising cathode materials for hybrid electric vehicles and electric vehicle （EV） high energy density lithium-ion batteries in recent years due to its high specific capacity， high operating voltage， and low cost. The further development of electric vehicle technology requires the commercial application of lithium-ion batteries with a high energy density of approximately 350 Wh·kg-1 and a range of 500 km. However， the rapid capacity decay and structural instability of nickel-rich layered cathode materials hinder their market application. In this paper， the fundamental issue of performance degradation in nickel-rich layered cathode materials was summarized， and the latest progress and perspectives in improving the cycling stability of nickel-rich layered cathode materials through element doping， element ratio，surface reconstruction， particle arrangement，interparticle filling，particle size， single crystal transformation，and other aspects were summarized. It is pointed out that efforts could be made to construct high structural strength nickel-rich cathode materials through the coordination of elements and structures to fundamentally solve the structural and thermal stability problems under deep delithiated state， providing modified new processes and methods for nickel-rich layered cathode materials.

In order to carry out the high acceleration impact detection of the internal electronic equipment of the ship and to improve the detection capability of the impact testing machine, the traditional impact testing machine was structurally improved, and a new type of hedge type impact testing machine was designed, and the design parameters and its dynamic characteristics were studied. Firstly, the mechanical structure and control principle of the hedge impact testing machine were introduced, the kinematic model of the equipment was established, and the test action was divided into four processes, which were energy storage, release, collision and braking stages. The mathematical modeling analyses of each stage were carried out, and the maximum energy collision point was determined. Then, solid models were developed and computer simulations were performed using ANSYS software to assess structural stability and impact acceleration predictions. Finally, the dynamic characteristics of the device were examined through several tests, and the location of the collision point and the size of the impact acceleration generated by the device were repeatedly tested at different positions. The acceleration and displacement signals were collected, and the signals were processed by noise reduction filtering and differential calculation to verify the reliability of the device performance. The results of the study show that the structure of the testing machine is simple, easy to operate, and can be tested repeatedly. The dispersion of the distribution data of the collision point from the ideal position in each test is within 30 mm, the data is stable and reliable, which meets the design requirements, and the control method is reasonable. By adjusting the release position of the test bench and the impact table, the size of the acceleration generated by the impact can be changed, and the maximum impact acceleration of about 2 000 g can be generated when releasing at the limit position, which can satisfy the test requirements of various components for impact resistance testing.

Molybdenum disulfide (MoS2) is a classical layered transition metal sulfide, which exhibits excellent performance as cathode materials for lithium-ion batteries. In this research, hollow spherical nano-MoS2 was synthesized by thermal decomposition, and then the carbon coated MoS2 was prepared with dopamine hydrochloride as carbon source. Various characterization techniques such as XRD, SEM, and Raman spectroscopy were used to analyze the composition and structure of MoS2/C nano-composites. The size of MoS2/C nanocomposites is 150-250 nm and the thickness of carbon layer is 40-70 nm. The hollow spherical structure of nano MoS2 can effectively alleviate the intense volume change during cycling. The coating of carbon layer on the surface can effectively improve the conductivity of MoS2, and enhance the structural stability. As a result, this novel ordered structure delivers a high initial specific capacity of 1 132.1 mAh/g and remain 587.4 mAh/g over 50 cycles, thus exhibiting great potential as an anode composite structure for durable high-rate lithium-ion batteries.

The components synergistic affect the structure formation and complexity of anionic polymerization of blast furnace slag directly. The structure evolution of silicate polymerization with different i?2, to(MgO)/to( AI2O3 ) and to(Al2O3) changes was studied in this paper,thermodynamic calculation was used to determine the temperature rise regime and node for interrupting of the experiment. According to Raman spectrum analysis, it was found that when R2 and 00 (MgO)/oj( AI2O3 ) increased, the silicate anion groups in the blast furnace slag depolymerization occurred, and the structural units from Q4, Q3 to Qo, Qi and Q2 evolved, resulting in the deterioration of structural stability and the enhancement of slag fluidity. When the alkalinity is greater than 1. 2,ftj(MgO)/ftj(Al2O3) is greater than 0. 55, there is a reverse transformation or slowing trend. With the increase of ftj(Al2O3),it can be seen that the relative content of Qo changes little, the relative content of Qi increases first and then decreases, the relative content of Q2 decreases significantly,the relative content of Q3 increases significantly,the overall relative content of Q4 shows an increasing trends,the slag cluster structure tends to be complex,and the non-bridge oxygen content in the slag system shows a slow decreasing trend. When the content of to(Al2O3) exceeds 16%,the downward trend is more obvious. [ABSTRACT FROM AUTHOR]

The Yellow River basin is of critical strategic importance to China's economic and social development. The lower reaches are characterized by low flow rates and high sediment concentrations, exhibiting an uncoordinated water-sediment relationship. This results in a secondary-perched river phenomenon and a complex evolution of river form. The degradation of bank slopes poses a significant threat to flood control integrity and hinders the economic and social development. Therefore, the preservation of riverbank stability and the implementation of effective slope protection and risk reduction measures are essential. The degradation of ecological slopes is a complex issue, influenced by a synergy of hydrological, pedological, vegetative, and structural stability elements, regulated by intricate processes. The inadequacies of current river dynamics theories necessitate in-depth investigation on this topic. This study compiled the current state of bank erosion in the lower Yellow River, elucidated the factors contributing to slope instability, and assessed the state-of-the-art in ecological slope protection methodologies and the challenges in risk evaluation and management protocols. The study identified key directions for future research in ecological slope protection, including: unraveling the degradation processes under hydro-soilvegetation interactions; innovating rigid-flexible ecological slope protection structures adapted for intense alluvial conditions; developing comprehensive, tiered risk assessment models for ecological slope engineering; and constructing integrated frameworks for the monitoring, evaluation, and control of riverbank slope integrity.

(Objective) This study aimed to make high-value use of pig blood and improve the application range of pig hemoglobin (Hb). (Methods) Hb was modified by enzymolysis and phosphorylation, and its optimum preparation conditions and characteristics were explored. The optimal parameters were determined by response surface test to study the effect of enzymatic hydrolysis-phosphorylation of porcine hemoglobin (HP-Hb). (Results) The optimal parameters for phosphorylation were 10 g/100 mL phosphate addition, pH 9, 8 g/100 mL pig hemoglobin peptide (pig hemoglobin peptide, H-Hb) addition, and a reaction time of 2.1 hours. Compared with Hb and H-Hb, HP-Hb showed significantly improved emulsification properties and antioxidant activity. Electrophoresis results indicated no significant change in molecular weight. Structural analysis revealed that the phosphate groups were mostly attached to the N atoms. The change of secondary structure of HP-Hb enhanced its structural stability. (Conclusion) Enzymolysis phosphorylation co-modification significantly improved the emulsification property, antioxidant property and thermal stability of porcine hemoglobin, indicating that co-modification is a feasible method to improve protein.

Corn peptide-iron chelates serve a dual purpose, enhancing the utilization of corn peptides while also offering a novel approach for the development of iron supplements. To examine the structural properties and thermal stability of corn peptide-iron chelates, samples of this compound were prepared from corn peptides and ferrous chloride. Following ultraviolet spectroscopy and thermogravimetric analysis, the binding sites of the identified corn peptide fragments and ferrous ions were simulated by molecular docking. The stability of the corn peptide-iron chelate was observed at different temperatures and pH values, as well as under different in vitro digestion conditions. The results showed that the ultraviolet absorption peak changed. More specifically, the characteristic absorption peak shifted from 274.99 nm to 275.01 nm. Moreover, the corn peptide and corn peptide-iron chelate were compared and found to differ in a number of their properties. Thermogravimetric analysis revealed residual rates of 34.94% and 18.74% for corn chelate and peptide, respectively, while thermal stability of the corn peptide-iron chelate was found to be significantly higher that of the corn peptide. The binding energy levels of FSAASYPDLIDALP and LQQRQQLLNPL with Fe2+ were -50.50 and -48.61 kJ/mol, respectively, and the amino group of Asp8 (aspartic acid) was found to provide the ligand site. In addition, Pro7 (proline), Ser5 (serine), Tyr6 (tyrosine), and Leu7 (leucine) were found to bind to the ferrous ions to form hydrophobic interactions. The relative molecular masses were mostly below 1 000 u under the action of different temperatures. In addition, small peptides were more easily chelated and absorbed, and were stable under relatively alkaline conditions. [ABSTRACT FROM AUTHOR]

Per- and polyfluoroalkyl substances (PFAS) could induce hepatotoxicity through the activation of peroxisome proliferator-activated receptor α (PPARα). However, the molecular mechanism of PFAS-induced PPARα activation remains unclear. This study calculated the binding free energy (ΔGbind) of seven legacy and emerging PFASs with PPARα based on Gaussian accelerated molecular dynamics (GaMD) and molecular mechanics-generalized Born surface area (MM-GBSA). The results indicated a significant correlation (r=0.82, P<0.05) between ΔGbind and the logarithmic value of half maximal effective concentration (logEC50) of PFAS activating PPARα. Additionally, the number of fluorocarbon atoms positively correlated with ΔGbind, and PFAS containing carboxyl groups generally had a lower ΔGbind compared to those containing sulfonate groups. The activation activity of PFAS towards PPARα was found to be directly associated with their binding patterns within the PPARα ligand-binding pocket, as revealed through the analysis of structural stability, hydrogen bond distribution and ligand-residue contacts. PFAS with stronger activities were observed to preferentially bind within the pocket composed of H3, H7, H11 and H12, interacting with key residues such as ILE354, HIS440 and CYS276. These results contribute to the screening of PFAS with PPARα activation effect, and support the evaluation of toxic effects of PFAS. [ABSTRACT FROM AUTHOR]

Objective In geological conditions with water-rich sandy stratum, research on the structural stability of existing metro lines with new metro line shield launching crossing is relatively scarce. It is essential to summarize relevant patterns for similar projects. Method Leveraging the structural engineering of shield launching crossing the existing Line 2 at Huanghe Yingbinguan Sta.-Yingcai Road Sta. interval on Zhengzhou Metro Line 7 as basis, according to actual working conditions, a 3D numerical model of the constructed interval is established using finite element software MIDAS GTS NX, and simulation results for the project corresponding model are obtained using the software result-extraction function. Two monitoring points are selected at the site, and the field-monitored values of them are compared with the simulated values to confirm the model accuracy. On this basis, the influence on existing metro line structural stability under shield launching and conventional under-passing two tunneling methods are further studied. The influence of four values of the vertical distance d between launching portal and existing metro structure is explored. Result & Conclusion The established 3D model, to a certain extent, reflects the actual working conditions. Keeping factors such as the structure, material, and reinforcement method of the existing metro line unchanged, the structural stability of existing metro line varies depending on the tunneling methods. Compared to conventional under-passing construction method, the shield launching crossing causes less influence on the existing metro line structure. When this method is adopted, different d values cause different degrees of impact on existing metro line structural stability. In the case of d=2.00 m, its influence on existing metro line structure is minimal, and the engineering cost is relatively low. It is recommended to adopt shield launching under-passing method under permissible engineering conditions, and the suggested value is d=2.00 m.

Objective To analyze the construction impact of new large-span civil defense tunnel on metro tunnel interval structural stability when under-passing existing metro line with a small clear distance, it is necessary to conduct a simulation study of the civil defense tunnel under-passing construction process. Method Leveraging a flat large profile civil defense tunnel under-passing existing metro tunnel interval project in Qingdao, a three-dimensional finite element model is established to simulate the whole process of civil defense tunnel excavation. The mechanical response and deformation patterns of the diaphragm wall set in the civil defense tunnel during excavation is emphatically analyzed, as well as the impact of overall construction process on existing metro station and tunnel interval. Result & Conclusion The civil defense tunnel diaphragm wall exhibits a noticeable biasing trend during the construction of both the leading and trailing holes. In the initial support phase of the civil defense tunnel, a rare ′four-quadrant′ distribution pattern is observed due to the combined effects of the existing metro tunnel upper arching effect and the diaphragm wall, with higher settlement values on the right side compared to the left side. The existing metro stations and interval structures experience a significant impact from the civil defense tunnel excavation space effect, with deformation trends moving towards the excavation side, while the deformation values are all below the regulation-specified warning limits.

In order to study the effect of epigallocatechin on the oxidation of myosin in sea bass under microwave heat-ing,differentmass concentrations of epigallocatechin (20,40 /g/mL and 60 /g/mL) were used to inhibit myosin oxidation and study the mechanism of its effect on myosin. EGC could delay the increase of carbonyl content and dityrosine of myosin and the decrease of total sulfhydryl content after microwave treatment. Carbonyl content was reduced by 19.82%- 72.67% compared with the control. AFM showed that the myosin treated with EGC were small and evenly distributed. Microwave induced myosin to unfold and increased fluorescence intensity. EGC maintained the relative stability of the tertiary structures and delayed the increase of fluorescence intensity.Before microwave, low mass concentration EGC (20, 40 /g/mL) significantly increased a helix content and maintained the stability of myosin secondary structure. After microwave, 20 /g/mL EGC maintained the stability of secondary structure. Molecular dynamics simulation showed that RMSF and RMSD value of myosin-EGC decreased, SASA decreased, secondary structure fluctuation decreased. It was found that myosin enhanced the stability of the complex under heating electric field by hydrogen bonding and hydrophobic interaction with EGC. [ABSTRACT FROM AUTHOR]

Supercapacitors have attracted much attention because of their high power density, fast charging / discharging speed, and long cycle life. However, the low energy density restricted their wide application. Developing novel and efficient electrode materials is imperative to improve the electrochemical performance of supercapacitors. Metal-organic frameworks (MOFs) have attracted extensive attention in the field of energy conversion and storage, owing to their large specific surface area, controllable pore size, rich active sites and easy synthesis. Nevertheless, due to the inferior structural stability and low conductivity of MOFs, the electrochemical performance of supercapacitors with MOFs electrode materials is unsatisfactory. MOFs derivatives, prepared from the MOFs precursor, possess excellent structural stability and conductivity, thus prominently improve the electrochemical performance of supercapacitors. This work mainly focuses on the MOFs-derived electrode materials for supercapacitors, including MOFs-derived carbides, oxides, hydroxides, phosphides and sulfides. The synthesis strategies of electrode materials for supercapacitors are discussed, providing guidance for the research of nano-MOFs-derived materials for supercapacitors. [ABSTRACT FROM AUTHOR]

There are significant differences in the CO2 content of the synthesis gas obtained from different raw materials, but they can all be converted to methanol through the catalysis of traditional methanol catalysts. In order to study the effect of syngas with different CO2 content on the structure and performance stability of the catalysts, methanol synthesis was performed in an industrial-sized tubular jacketed reactor using simulated coal gasification and natural gas conversion syngas, and the changes of microparticles and catalyst performance stability of the original particle industrial catalysts before and after use were studied. The results show that the sizes of Cu and ZnO particles increase before and after the use of the five original industrial catalysts, and the sizes of Cu and ZnO particles increase faster under the conditions of synthetic gas produced by natural gas conversion. The overall performance of catalysts is limited, which is not conducive to maintaining the stability of catalyst performance. High CO2 content is more likely to destroy the stability of Cu+ and lead to the transformation of Zn species morphology. [ABSTRACT FROM AUTHOR]
