Electrochemical Analysis of Direct Methanol Fuel Cells for Low Temperature Operation
International Journal of Electrochemical Science, 2006 The electrochemical behaviour of Direct Methanol Fuel Cells (DMFCs) was investigated at low temperatures (30°C-60°C). An 85 wt% Pt-Ru (1:1 a/o)/C anode catalyst and a 60 wt% Pt/C cathode catalyst were in-house prepared and characterised. The influence of

FEBS Open Bio, EarlyView.We investigated the toxicity of 12 active compounds commonly found in herbal weight loss supplements (WLS) using human liver and colon cell models. Epigallocatechin‐3‐gallate was the only compound showing significant toxicity. Metabolic profiling revealed protein degradation, disrupted energy and lipid metabolism suggesting that the inclusion of EGCG ...

Modulating Electrochemical CO2 Reduction Pathways via Interfacial Electric Field
Advanced Functional Materials, EarlyView.Engineering interfacial electric fields in Cu/ITO electrodes enables precise control of CO2 reduction pathways. Charge transfer from Cu to ITO generates positively charged Cu species that steer selectivity from ethylene toward methane. This work demonstrates how interfacial electric‐field modulation can direct reaction intermediates and transform ...
