Abstract null null It is very promising and challenging to design electrocatalysts with high activity for oxygen reduction reaction (ORR), oxygen evolution reaction (OER), and hydrogen evolution reaction (HER). Graphene-like germanium carbide (g-GeC) is a new candidate in the field of electrocatalysis due to its stable structure, high specific surface, and adjustable electronic properties. In this work, we systematically studied the electrocatalytic activities towards ORR, OER, and HER of the 3d...

Abstract null null The insertion of an increasing amount of N-vinylpyrrolidone (VP) in statistical copolymers based on thermoresponsive poly(N-vinylcaprolactam) (PVCL) enables one to modulate the properties of the copolymer and those of the corresponding gold nanoparticles (AuNPs)-polymer hybrid materials. The incorporation of VP not only affects the growth of AuNPs synthesized in the presence of the polymers (in situ route), but also the properties (stabilization, optical, catalytic...) of pref...

Abstract null null Oxygen plasma treatment was applied to atomically flat quartz surfaces in order to study the effect of surface activity on the adsorption of a silyl anchored quaternary ammonium salt biocide. Reduction of contact angle of the quartz surfaces were achieved from 72° to between 14° and 20° by applying oxygen plasma at increasing power between 100 W and 500 W. XPS analysis of the plasma-treated quartz surfaces indicated an increase in the presence of oxygen, implying the conversio...

Abstract null null Activated carbons (ACs) have been widely used for dye removal and for H2 storage but often demonstrate limited performance due to their low porosity and lacking beneficial surface functional groups. Herein, we have designed a series of urea/thiourea and K2CO3 modified ACs from “sucrose – a biomass-derived carbohydrate” via two-step pyrolysis/activation method. As-prepared ACs demonstrate excellent textural features (e.g., specific surface area (SSA) = 2842 m2/g; pore volume = ...

Abstract null null Strong solar capture and high heat transfer are extremely vital for designing solar-to-heat absorber to improve photo-thermal conversion efficiency in direct absorption solar collectors (DASCs). In this paper, the plasmonic nanofluids containing reduced graphene oxides (rGO) decorated with titanium nitride (TiN) nanoparticles were prepared. Their superior solar-thermal conversion efficiency and heat transfer property was based on the synergy between the Localized Surface Plasm...

Abstract null null To widen applications of ground calcium carbonate (GCC), it is crucial to improve whiteness and remove the black-colored impurities (Fe, Mn and Zn) from GCC powders. Herein a new strategy termed as sodium dithionite-sodium citrate-sulfuric acid treatment (DCS) was developed to whiten natural GCC powders, and the whiteness was improved from 85% to 95.6%. The DCS strategy was adopted by washing GCC with aqueous solution of sodium dithionite, sodium citrate and sulfuric acid (Na2...

Abstract null null Superhydrophobic nanocomposite coating was designed using nanodiamonds (NDs) and siloxane-acrylic resins via the spray coating process. The NDs coating showed a high-water contact angle of 154° and a very low sliding angle of 6°. After 10 cycles of icing and de-icing, the coating exhibited a delay in ice formation time and reduced ice adhesion strength (~44.56 KPa) in comparison with the bare metal (~77 KPa). The superhydrophobic nanocomposite coating offers excellent anti-bac...

Abstract null null China's Puguang gas field has abundant reserves of high sulfur-bearing natural gas, but sulfur deposition problems have hindered the development of the reservoir. Many experimental and predictive models have been applied to this issue, but few studies have addressed it from a microscopic perspective. Thus, we developed a molecular model of calcite and monolithic sulfur, studied the adsorption mechanism of sulfur molecules on the calcite {10 null null null null 1 null null null...

Abstract null null The selectivity of a novel mineral beneficiation technology utilizing a water in oil emulsion as the binder for mineral agglomeration has been investigated. This novel technology can agglomerate fine and ultrafine hydrophobic mineral particles in less than 7 s thus providing an option for the beneficiation of low-grade ores or rare earth metal oxides, metal sulphides or platinum group metals (PGMs). However, the selectivity of the process is compromised by the interaction of e...
