Critical Role of HAP Support Micro-Nanostructure for High Activity and Stability of Ag/HAP Nanocatalysts in Toluene Oxidation

Journal of Chemistry
In this study, the hydrothermal method, the coprecipitation method, and the sol–gel method were used to control the synthesis of HAP supports. It was found that the HAP-S carrier prepared by the sol–gel method has a unique micro-nanostructure advantage ...

Electronic Modifictions in Supported Palladium Catalysts

, 1994
XPS and IR spectroscopy indicate that the electron density of the supported metal clusters in Pd/LTL catalysts is a function of the support acidity/alkalinity. In addition, the neopentane and propane hydrogenolysis TOF's increase with increasing support acidity from alkaline to acidic.

Hydrostatic pressure activates HIF‐1α via β‐catenin to promote stemness in breast cancer cells

FEBS Open Bio, EarlyView.
To mimic the elevated intestinal fluid pressure in breast cancers, we loaded human breast cancer cells (MCF‐7, MDA‐MB‐453, and BT‐474) to 50 mmHg hydrostatic pressure. Hydrostatic pressure exposure upregulated HIF‐1α and induced stemness in MCF‐7 and BT‐474 cells.

Highly Tunable Catalyst Supports for Single-Site Ethylene Polymerization

, 2016
A new class of tunable crystalline solid supports for metal complexes has been synthesized and used for ethylene polymerization. We developed a family of high surface area, highly dispersible layered double hydroxides (AMO–LDHs) which, on treatment with

Polyoxometalate Modified Carbon Supported Pd-Cu Bimetallic Catalyst For Formic Acid Oxidation

International Journal of Electrochemical Science, 2019
Palladium-copper (PdCu) bimetallic alloy nanoparticles were loaded on the polyoxometalate modified carbon supports (PWA-C) to prepare PdxCuy/PWA-C catalyst with different Pd/Cu atomic ratios. Highly dispersion catalyst nanoparticles were obtained and its

The crystal structure of the Borrelia burgdorferi nicotinamidase BBE22 resolves a long‐standing annotation error

FEBS Open Bio, EarlyView.
The crystal structure of Borrelia burgdorferi nicotinamidase (PncA/BBE22) reveals the correct full‐length protein initiated from a non‐canonical AUU start codon. The structure validates previous biochemical findings and resolves a long‐standing annotation error, demonstrating that the truncated database sequence is structurally incompatible with the ...
