Modeling interfacial electric fields and the ethanol oxidation reaction at electrode surfaces.

The electrochemical environment present at surfaces can have a large effect on intended applications. Such environments may occur, for instance, at battery or electrocatalyst surfaces. Solvent, co-adsorbates, and electrical field effects may strongly influence surface chemistry.

Enhanced electrochemical stability and ion transfer rate: A polymer/ceramic composite electrolyte for high-performance all-solid-state lithium-sulfur batteries.

All-solid-state (ASS) lithium-sulfur (LiS) batteries utilizing composite polymer electrolytes (CPEs) represent a promising avenue in the domain of electric vehicles and large-scale energy storage systems, leveraging the combined benefits of polymer electrolytes (PEs) and ceramic electrolytes (CEs). However, the inherent weak interface compatibility between PEs and CEs often leads to phase separation, thereby impeding the transposition of Li. In this study, the trimethoxy-[3-(2-methoxyethoxy)propyl]silane (TM-MES) is introduced as a chemical agent to form bonds with polyethylene oxide (PEO) and LiGePS (LGPS), resulting in the development of a novel composite polymer electrolyte (CPE).

Overcoming slow removal efficiency-induced highly toxic I-DBPs in water by oxygen vacancies enriched invasive plant biochar catalyst: Experimental and theoretical studies.

Developing effective and safe catalysts operated in the in-depth removal of iodinated X-ray contrast media is important for overcoming slow removal efficiency-induced highly toxic iodine-replaced disinfection byproducts (I-DBPs). In this study, a novel oxygen vacancies enriched heterogeneous biochar catalyst (Mo-Co-ECM) from the invasive plant was synthesized by a facile one-step hydrothermal carbonization method and used for the in-depth removal of iohexol (IOH) by the activation of peroxymonosulfate (PMS). The results indicated that after adding PMS for 3 min, the removal efficiency of IOH in Mo-Co-ECM/PMS system reached 100% and exhibited a superior degradation efficiency compared to Co-ECM/PMS and ECM/PMS system.

Preferences and Perceptions of Workplace Participation: A Cross-Cultural Study.

Despite the amount of theorization on the forms and effects of participation, relatively little research directly examines what the concept of workplace participation entails in the minds of employees, and whether employees across cultures think positively when the concept of participation is activated in their mental representation. Three studies ( = 1,138 full-time employees) investigated the perceptions and preferences of full-time employees from the United States and China, cultures that might be expected to differ in their societal participation norm. Using a free association test and text analyses, Study 1 demonstrated that Chinese and American employees differed in their construal of workplace participation, yet both culture groups associated positive valence to the concept of participation.

An evaluation of solvent effects and ethanol oxidation.

Understanding liquid-metal interfaces in catalysis is important, as the liquid can speed up surface reactions, increase the selectivity of products, and open up new favorable reaction pathways. In this work we modeled using density functional theory various steps in ethanol oxidation/decomposition over Rh(111). We considered implicit (continuum), explicit, and hybrid (implicit combined with explicit) solvation approaches, as well as two solvents, water and ethanol.

Conversion of Ethanol via C-C Splitting on Noble Metal Surfaces in Room-Temperature Liquid-Phase.

Rh-catalyzed decomposition of ethanol into CO and CH via C-C bond splitting is reported in room-temperature liquid phase under atmospheric pressure. Mechanistic investigations show that C-C bond splitting of ethanol on the noble metal surface is rapid, and CO forms through the oxidation of α-CH O and β-CH fragments after C-C bond splitting, while CH forms through the hydrogenation of β-CH utilizing H atoms from -OH, β-CH , and α-CH OH fragments.
