Surface charge as activity descriptors for electrochemical CO reduction to multi-carbon products on organic-functionalised Cu.

Intensive research in electrochemical CO reduction reaction has resulted in the discovery of numerous high-performance catalysts selective to multi-carbon products, with most of these catalysts still being purely transition metal based. Herein, we present high and stable multi-carbon products selectivity of up to 76.6% across a wide potential range of 1 V on histidine-functionalised Cu.

Polaron Delocalization Dependence of the Conductivity and the Seebeck Coefficient in Doped Conjugated Polymers.

Conjugated polymers are promising materials for thermoelectrics as they offer good performances at near ambient temperatures. The current focus on polymer thermoelectric research mainly targets a higher power factor (PF; a product of the conductivity and square of the Seebeck coefficient) through improving the charge mobility. This is usually accomplished structural modification in conjugated polymers using different processing techniques and doping.

Quantification of aflatoxin B in vegetable oils using low temperature clean-up followed by immuno-magnetic solid phase extraction.

In the present study, a convenient and highly efficient method was developed to quantify aflatoxin B (AFB) in oil samples. Low temperature clean-up (LTC) followed by immuno magnetic solid phase extraction (IMSPE) was used to clean up oil samples. LTC assisted in freezing out the interference from the oil matrix while IMSPE further helped to preconcentrate the targeted analyte.
