Design of Pd–Zn Bimetal MOF Nanosheets and MOF-Derived Pd_3.9Zn_6.1/CNS Catalyst for Selective Hydrogenation of Acetylene under Simulated Front-End Conditions

Molecules, 2022
Novel zinc–palladium–porphyrin bimetal metal–organic framework (MOF) nanosheets were directly synthesized by coordination chelation between Zn(II) and Pd(II) tetra(4-carboxyphenyl)porphin (TCPP(Pd)) using a solvothermal method.

Cold plasma chemistry and diagnostics [PDF]

Vacuum, 2011
5 páginas, 3 figuras.- El pdf esta en formato pre-print. This paper gives an overview of the main chemical processes which take place in cold plasmas generated in glow discharges, both in the gas phase and at the surfaces in contact with the plasma. Illustrative examples are provided where the relevance of different processes is evinced.

Gas phase production of NHD2 in L134N [PDF]

, 2001
We show analytically that large abundances of NH2D and NHD2 can be produced by gas phase chemistry in the interiors of cold dense clouds. The calculated fractionation ratios are in good agreement with the values that have been previously determined in ...

Decrystallization of Crystals Using Gold “Nano-Bullets” and the Metal-Assisted and Microwave-Accelerated Decrystallization Technique

Molecules, 2016
Gout is caused by the overproduction of uric acid and the inefficient metabolism of dietary purines in humans. Current treatments of gout, which include anti-inflammatory drugs, cyclooxygenase-2 inhibitors, and systemic glucocorticoids, have harmful side-

Target binding triggers hierarchical phosphorylation of human Argonaute-2 to promote target release

eLife, 2022
Argonaute (Ago) proteins play a central role in post-transcriptional gene regulation through RNA interference (RNAi). Agos bind small RNAs (sRNAs) including small interfering RNAs (siRNAs) and microRNAs (miRNAs) to form the functional core of the RNA ...
