In the present work, CO 2 -storage materials (CO 2 SMs) obtained from CO 2 capture were applied as energy sources to facilely boost the growth of four vegetables including eggplant, tomato, pimiento, and cucumber. The effects of CO 2 SMs on the vegetable growth were determined by irrigating plants with different CO 2 SMs fertilizers for 60 d using water and NH 4 HCO 3 as the control groups. The results indicated that all CO 2 SM fertilizers dramatically promoted the plant growth of the tested vegetables in terms of plant height, stem diameter, and root development. Further investigation revealed that CO 2 in CO 2 SMs functioned as an indirect energy source to improve the root development, which increased the absorption of nutrients from the soil to further promote both vegetative growth florescence and yield. Our work has provided a new strategy for CO 2 utilization as an indirect energy source. [ABSTRACT FROM AUTHOR]

In this work, electron irradiation as a novel and simple method was used to fabricate wearable strain sensors with high comprehensive performance. Hydroxylated multi-walled carbon nanotubes (hydroxylated MWCNTs) were uniformly adsorbed on ecoflex etched by hydrofluoric acid (HF). After electron irradiation, a large number of defects and functional groups were successfully introduced into the hydroxylated MWCNTs/ecoflex, leading to a flexible strain sensor with high comprehensive performance such as ultra-low detection limit, fast response, and wide sensing range. Compared with the unirradiated sensors, the irradiated sensors have an ultra-low detection limit of 0.01% and a wide strain range (the maximum strain of 800%), the maximum gauge factor is increased by 344%, and the response time and recovery time are reduced by 50% and 89.2% respectively. The sensors can be used for monitoring the weak physiological movements and large-scale human movements, which has great potential in health monitoring. The electron irradiation as an activate method can provide a way for mass fabrication of flexible sensors with high comprehensive performance such as ultra-low detection limit and wide sensing range.

Carbon disulfide (CS 2) is seen an odor-toxic organic sulfur compound, which presents a major impact on global climate change. Therefore, the conversion of CS 2 into valuable chemicals is the key to reduce the concentration of CS 2 in the atmosphere. On the basis of a CS 2 fixation strategy, CS 2 -storage materials (CS 2 SMs) are firstly synthesized by the reaction of CS 2 with a binary ion-like liquid systems of ethylenediamine (EDA) and ethylene glycol derivatives (EGs) under mild condition. In view of the serious shortage of sulfur fertilizer and its important position in global agricultural production, it is a promising choice to use the CS 2 SMs as a new type of green sulfur fertilizer to promote the growth of eggplant, tomato, sweet pepper and cucumber. In this work, the influence of CS 2 SMs on the growth of plants were studied by taking plants irrigated by using various aqueous CS 2 SMs solutions as experimental groups, and those irrigated by using water and NH 4 HCO 3 as control groups. The experimental results showed that all CS 2 SMs could promote plant height, stem diameter, root weight, flower bud number and leaf size. Especially, several CS 2 SMs presented significant influence on fluorescence and fruit number. Further studies showed that the CS 2 SMs as new energy resources sulfur-containing boosted leaf area, improved root development, enhanced photosynthesis and soil nutrient uptake, and promoted vegetative and reproductive growth of these four types of plants. Thus, this work provided a new strategy for the use of CS 2 as an indirect energy source for the experimental four plants. Schematic illustration for the preparation processes of CS 2 SMs, and CS 2 used as an indirect sulfur source to promote fluorescence and fruit number of plants.

In the past two decades, a large number of organic sulfur compounds such as CS 2 have been released into the atmosphere, which has caused some impacts on the environment. At present, most of the industrial treatment methods of CS 2 have a series of problems, such as high energy consumption, the use of catalysts and additional treatment of by-products, which are not advisable from the economic point of view. Therefore, in this work, a method of efficient and rapid storage of CS 2 by EDAs + EGs ionic liquid systems at room temperature and pressure without catalyst were proposed. At the same time, the change trend of temperature and conductivity of EDAs + EGs systems during CS 2 storage were determined. Secondly, in order to realize the resource utilization of CS 2 SM, the mechanism of EDAs + EGs system storage CS 2 and the properties of CS 2 SM were further studied by NMR, FTIR, XPS, XRD and other modern spectral techniques. The results showed that white precipitate with high melting point (127–224 °C) and high thermal stability were formed after CS 2 is stored in the systems. These white precipitates had a similar chemical structure ([+H 3 NR 1 NH 3 +−SC(=S)OR 2 (R 3)O(S =)CS−] n), which were named as carbon disulfide storage material (CS 2 SM). Furthermore, CS 2 SMs were used as raw materials to one-step synthesize nano-metal sulfides (MSs) with excellent photocatalytic activity in the reduction of CO 2. This provides a new method for the rapid storage and utilization of CS 2 , and it also has important practical significance for reducing CS 2 emissions and realizing effective utilization of CS 2. This efficient, green and universally applicable CS 2 capture method is of great significance to reduce its hazards and obtain valuable chemicals. Image 1 [ABSTRACT FROM AUTHOR]

• SiO 3 2− from coal gangue to prepare four nano-materials for CO 2 adsorption. • A high SiO 3 2− leaching rate of 77.69% from coal gangue. • Optimal preparing conditions for nano-materials by surface response analysis. • Four nanomaterials with high capability for recycle CO 2 capture with high selectivity. As one of the most important approaches to reduce CO 2 emission from various combustion processes, CO 2 adsorption capture is facing several many challenges, including high adsorbent cost, high energy cost, and low CO 2 selectivity. In this work, four novel silicate-based nanomaterials (SBNMs), including magnesium silicate (MgSiO 3), manganese silicate (MnSiO 3), copper silicate (CuSiO 3) and zirconium silicate (ZrSiO 4), were fabricated via hydrothermal method with SiO 3 2− extracted from coal gangue (CG) for the adsorption capture of CO 2. Under the optimum conditions, the SiO 3 2− extraction ratio from the CG reached to 77.69%. The extracted SiO 3 2− was used to synthesize SBNMs with high surface area and high thermal stability, which were characterized with Fourier transform infrared spectroscopy, X-ray diffraction, transmission electron microscopy, and nitrogen adsorption/desorption isotherms technologies. These as-obtained SBNMs exhibited CO 2 adsorption capability of (7.82–17.93) cm3/g at 25 °C under 1 atm, respectively. The CO 2 adsorption data were successfully fitted with Freundlich model, and the adsorption processes were obvious chemically favored, spontaneous and exothermic according to thermodynamic parameters, including Qst, Δ G ads , Δ H ads and Δ S ads. Significantly, all SBNMs showed a excellent cycle performance and strong selectivity toward CO 2 over N 2. The aim of this work is to provide a new method of utilization of coal gangue waste and a low-cost, and highly selective CO 2 adsorbents. [ABSTRACT FROM AUTHOR]
