Effectors secreted by the type Ill secretion system are essential for bacterial pathogenesis. Members of the Yersinia outer-protein J (YopJ) family of effectors found in diverse plant and animal pathogens depend on a protease-like catalytic triad to acetyl ...
Developing efficient catalysts for electrolysis, in particular for the oxygen evolution in the anodic half cell reaction, is an important challenge in energy conversion technologies. By taking inspiration from the catalytic properties of single-atom cataly ...
Metal-free heteroatom-doped carbocatalysts with a high surface area are desirable for catalytic reactions. In this study, we found an efficient strategy to prepare nitrogen, phosphorus, and sulfur co-doped hollow carbon shells (denote as NPS-HCS) with a su ...
The fouling of neurotransmitter during electrochemical detection can dramatically jeopardize the viability of the sensor. Several recent developments in electrode fabrication and design have helped mitigating this issue. For instance, carbon nanotube fiber ...
Sn-beta zeolites prepared using different recipes feature very different catalytic activities for aqueous phase glucose isomerization, suggesting the presence of different active sites. A systematic study of the morphology and atomic-level structure of the ...
Here, we report hydrogen peroxide generation at 2-nitrophenyloctyl ether (NPOE)-water interface with decamethylferrocene as an electron donor. The progress of this reaction was detected by the observation of color change of the organic and aqueous phases i ...
Despite significant advances in the fabrication and applications of microreactors for production of chemicals, their use for catalytic reactions remains a challenge, especially in fine chemical synthesis where the selectivity towards the desired product is ...
The paper focuses on theoretical and experimental aspects of an oxide surface optimization for oxygen reduction reaction (ORR). Various doped alpha-MnO2 based electrocatalysts were prepared by microwave-assisted hydrothermal synthesis and electrochemically ...
Two N,N-bis(diphenylphosphino)-amine ligands [amine = 4-aminomorpholine (L-1) or 1-amino-4-methylpiperazine (L-2)] and their Pd(II) complexes were synthesised and characterised by IR and NMR spectroscopies. The structures of ligand L-1 and both complexes C ...
The excellent bifunctional catalytic activity of nickel phosphide (Ni2P) for water splitting is reported. Ni2P, an active hydrogen evolving catalyst, is shown to be highly active for oxygen evolution. Only 290 mV of overpotential is required to generate a ...
