Abstract Cu shows unique characteristics for electrochemical CO 2 reduction reaction (CO RR) to hydrocarbons and oxygenates due the moderate adsorption energy of key intermediate *CO. However, it remains a challenge selectively control RR towards C 1 (e.g., CH 4 ) or 2+ H 5 OH) through simple interface engineering. Herein, series inverse catalysts, composed CeO nanoparticles over substrate (Cu‐CeO ‐x), are subtly designed tackle issues. It is verified decoration induces highly active Cu/CeO...

Electrochemical CO2-to-CO conversion is a significant alternative to lower CO2 emission and build carbon-neutral processes, as well produce CO, which can directly serve syngas precursor for Fischer–Tropsch synthesis. However, the easy water flooding of gas diffusion electrode (GDE) employed in flow cell during reduction reaction (CO2RR) electrolysis remains tough problem. Consequently, it breaks electrolyte/catalyst/CO2 triphase interface lowers FECO. Herein, combined inarching...

This article introduces the uses of transparent synthetic soil for geotechnical problems using optical system, including materials, sample preparation, properties, experimental methods, and applications in physical modeling. Four typical kinds are shown compared. For amorphous silica powder, normally consolidated has a higher normalized strength but lower modulus than natural clays. gels, stress-strain behaviors consistent with sand both dense loose conditions. fused silica, it shearing...

Novel two-dimensional (2D) membranes have been utilized in water purification or seawater desalination due to their highly designable structure. However, they usually suffer from swelling problems when immersed solution, which limits further applications. In this study, 2D cross-linked MXene/GO composite supported on porous polyamide substrates are proposed improve the antiswelling property and enhance ion-sieving performance. Transition-metal carbide (MXene) nanosheets were intercalated...

Proton exchange membranes (PEMs) are an important type of vanadium redox flow battery (VRFB) separator that play the key role separating positive and negative electrolytes while transporting protons. In order to lower ion permeability improve proton selectivity PEMs for enhancing Coulombic efficiency VRFBs, herein, various amounts nano-sized SiO2 particles were introduced into a previously optimized sulfonated poly(arylene ether) (SPAE) through acid-catalyzed sol-gel reaction tetraethyl...

In order to improve the output characteristics of electromagnetic energy harvester in a high-speed flow field, spring-coupling (SEGEH) is proposed, based on galloping large amplitude. The electromechanical model SEGEH was established, test prototype made, and experiments were conducted using wind tunnel platform. coupling spring can convert vibration consumed by stroke bluff body without inducing an electromotive force into elastic spring. This not only reduces amplitude, but it also...

Interface adhesion and stability between titanium carbon materials have been investigated by first-principles calculation, in which three different DFT-PBE, DFT-LDA optB88-vdW approaches are considered. Our calculation reveals that the formation of vacancy graphene would enhance interface increase interfacial strength, may be due to a strong hybridization atom sp2 dangling bonds carbons near vacancy. It is also found van der Waals interaction has less effects on cohesion properties...
