Surrogate‐Optimized Flow‐Guided Miniature Condenser for Rapid Exhaled Glucose Detection

Advanced Materials Technologies, EarlyView.
A surrogate‐optimized miniature condenser guides humid exhaled flow toward cold surfaces to accelerate exhaled breath condensate collection. By improving vapor access within a compact footprint, the design increases sample yield. This enables post‐collection enrichment and rapid colorimetric glucose detection from dilute exhaled biomarkers within a 5 ...

Characteristic volatile compounds in different parts of grass carp by comprehensive two-dimensional gas chromatography/time-of-flight mass spectrometry

International Journal of Food Properties, 2020
Freshwater fish are usually unpopular with people, mainly because of their unappealing earthy and fishy smell. Comprehensive two-dimensional gas chromatography is a relatively new analytical technique.

Using Comprehensive Two-Dimensional Gas Chromatography to Study the Atmosphere [PDF]

Journal of Chromatographic Science, 2010
The atmosphere is a highly complex, highly reactive chemical system. There are a huge variety of emission sources of chemical compounds, both natural and man-made, which have a broad range of reactivities and can be oxidized in the atmosphere to form an even more complicated matrix of oxidation products with a multitude of atmospheric lifetimes.

SuFEx‐Enabled Reprogramming of Flavonoids for Selective α‐Glucosidase Covalent Inhibition

Advanced Science, EarlyView.
Selective inhibition of intestinal α‐glucosidase remains limited by poor enzyme specificity and off‐target metabolic effects. Here, SuFEx click chemistry is used to reprogram natural flavonoids into covalent inhibitors with enhanced α‐glucosidase selectivity and controlled reactivity. This strategy enables effective regulation of carbohydrate digestion

High Free‐Volume Imidazole‐Based Ionomers for High‐Temperature Proton Exchange Membrane Fuel Cells

Advanced Science, EarlyView.
High free‐volume imidazole‐based ionomers (PF4IM‐72) enable enhanced phosphoric acid uptake and efficient proton transport, delivering peak power densities of 0.645 W cm−2 at 160 °C and 0.838 W cm−2 at 200 °C in HT‐PEMFCs. This work highlights a promising platform for next‐generation ionomers with improved high‐temperature performance and stability ...
