Selective low concentration ammonia sensing in a microfluidic lab-on-a-chip [PDF]
In the medical community, there is a considerable interest in a diagnostic breath analyzer for ammonia that is selectively enough to measure in exhaled air and small enough for the small volumes available in such an application.

PARP‐1 is a key enzyme in the DNA damage response, and its inhibition induces cancer cell death via synthetic lethality. Au(I)‐based drugs, such as aurothioglucose and sodium aurothiomalate, block PARP‐1's DNA‐dependent activity by targeting its zinc finger domains.

Thermodynamic Analysis of Working Fluids for a New “Heat from Cold” Cycle
Adsorptive Heat Transformation systems are at the interface between thermal and chemical engineering. Their study and development need a thorough thermodynamic analysis aimed at the smart choice of adsorbent-adsorptive pair and its fitting with a ...

Effect of Thiols for Nitrogen Reduction to Ammonia [PDF]
Ammonia is an important chemical used for fertilizers and also a potential carbon-free hydrogen storage medium. The Haber-Bosch process is the main production process, which requires large energy- and capital-input. Therefore, it is crucial to develop an

The nature of the potassium compound acting as a promoter in iron-alumina catalysts for ammonia synthesis [PDF]
The chemical form of the potassium promoter on an iron-alumina catalyst during ammonia synthesis has been studied by two methods, viz, (i) the measurement of the equilibrium constant of the process KNH2 + H2 KH + NH3, and (ii) chemical analysis of the ...

Dual targeting of RET and SRC synergizes in RET fusion‐positive cancer cells
Despite the strong activity of selective RET tyrosine kinase inhibitors (TKIs), resistance of RET fusion‐positive (RET+) lung cancer and thyroid cancer frequently occurs and is mainly driven by RET‐independent bypass mechanisms. Son et al. show that SRC TKIs significantly inhibit PAK and AKT survival signaling and enhance the efficacy of RET TKIs in ...

Global oceanic emission of ammonia: constraints from seawater and atmospheric observations [PDF]
Current global inventories of ammonia emissions identify the ocean as the largest natural source. This source depends on seawater pH, temperature, and the concentration of total seawater ammonia (NHx(sw)), which reflects a balance between ...

Sphingoid base structures, the sphingolipid backbones, vary among species. We established yeast cells in which the native sphingoid base was replaced with plant‐type bases containing cis or trans double bonds. This is, to our knowledge, the first eukaryotic model mostly composed of sphingolipids containing cis‐unsaturated sphingoid base, providing a ...
