The unique selectivity of Au/TiO2 for converting ammonium formate to CO2 in the presence of excess O2 and H2O without oxidising NH3 up to 300 °C is reported. The catalyst is highly stable and selective even after severe hydrothermal aging.

Developing low-temperature gas sensors for parts per billion-level acetone detection in breath analysis remains challenging for non-invasive diabetes monitoring. We implement dual-defect engineering via one-pot synthesis of Al-doped WO nanorod arrays, establishing a W-O-Al catalytic mechanism. Al doping induces lattice strain to boost oxygen vacancy density by 31.

A method for determination of ten kinds of sweeteners in soybean products by multi-plug filtration cleanup (-PFC) combined with ultra-high-performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS) was established. The sample was extracted with acetonitrile (containing 1% formic acid), degreased by using -hexane liquid-liquid extraction and purified by solid phase extraction using an -PFC column (Oasis PRiME HLB). The analytes were separated by using a Waters ACQUITY UPLC® BEH C (2.

Amyloidosis is caused by the extracellular deposition of amyloid fibrils with a β-pleated sheet structure. Diagnosis typically relies on Congo red or Thioflavine T staining. Recently, DAPI (4',6-Diamidino-2-Phenylindole), which is a common nuclear fluorochrome, has been reported to stain amyloid.

An analysis is conducted with the intention to clarify which molecules are more promising as renewable electricity storage media, taking into consideration some basic parameters like theoretical and practical voltage, theoretical energy density, etc. The central aspect of analysis is to apply sufficiently simple, but relevant criterion, the minimum cost of electricity required to produce a specific quantity of chemical energy storage medium, in relation to the prevailing market prices of the produced chemicals. Therefore, the study analyzes the cost of electrical energy needed to selectively convert CO into specific molecules such as, CO, CHOH, and CH, among others, water into hydrogen, and nitrogen into ammonia, by considering both idealized and more realistic operational conditions.

Recently, the atmospheric aerosol surface, which is reported to be quite acidic, is recognized as an important microreactive medium for atmospheric chemistry, profoundly impacting air quality and global climate. Nevertheless, the molecular-level understanding of the effect of surface-bound acids on atmospheric chemical reactions remains limited. Herein, the reactions between CO and NH/amines at the air-water interface with organic acids are investigated using combined molecular dynamic simulations and quantum chemical calculations.
