Influence of Cu2O Precursor Surface Orientation on Catalytic Performance and Product Selectivity in Nitrate Reduction Reactions

open access: yesChemistry – An Asian Journal, EarlyView.
For nitrate reduction to ammonia, oxide‐derived Cu electrodes were synthesized from Cu₂O with (100)‐ and (111)‐oriented surfaces. The precursor surface orientation influenced onset potential and product selectivity. Notably, the (100)‐derived electrode achieved higher Faradaic efficiency for ammonia, while the (111)‐derived electrode operated at a ...

Advances in Metal‐Free Transamidation: A Sustainable Approach to Amide Bond Formation

open access: yesChemistry – An Asian Journal, EarlyView.
This review highlights the recent developments of transamidation reactions under metal‐free reaction conditions. Various amines including weak nucleophilic amines such as aromatic amines have been used to achieve the transamidation reactions under mild and relatively green reaction conditions. Abstract The amide functionalities are a crucial functional

Fabrication of Polypyrrole–Polystyrene Sulfonate by Amperometric Biosensor‐Based Electropolymerization for Cholesterol Determination in Serum

open access: yesBiotechnology and Applied Biochemistry, EarlyView.
ABSTRACT Since cholesterol triggers many diseases, many methods have been developed for its determination. In this study, an alternative system for cholesterol determination was developed by preparing amperometric biosensors. In the development of the biosensor, Pt/polypyrrole–polystyrene sulfonate film was prepared by electropolymerization of ...

Nitrite‐reducing performance of two Lactobacillus strains isolated from traditional Sichuan fermented sausage in different production processes

open access: yesFood Bioengineering, Volume 1, Issue 3-4, Page 307-318, December 2022., 2022
This study screened Pediococcus pentosaceus and Leuconostoc mesenteroides insects in traditional Sichuan sausages and determined their nitrite‐reducing properties during different production processes. These two strains are expected to be the starting point for the improvement of biological safety and nitrite residue control in traditional Sichuan ...
