Engineered Porous Metal Structures via Electroplating in Two-Photon Polymerized Molds

Proceedings
We report the realization of metallic 3D microstructures, electroplated in two-photon polymerized molds. These molds are typically 150 × 150 × 30 µm3 in size and the smallest feature size is about 1 µm.

Stability enhancement for silver catalyst in ethylene epoxidation by support treatment

Catalysis Communications, 2023
The high cost of the silver catalyst for ethylene epoxidation to ethylene oxide (EO) requires the development of the catalyst with a lower silver loading and a longer catalyst life span. Preventing silver particles from clustering could help maintain the

Pd nanoparticles confined in mesoporous N-doped carbon silica supports: a synergistic effect between catalyst and support [PDF]

, 2020
Palladium nanoparticles of similar size were deposited on different supports, layers of carbon materials (with and without nitrogen doping) on the surface of a MCF (mesocellular foam) silica.

By dawn or dusk—how circadian timing rewrites bacterial infection outcomes

FEBS Letters, EarlyView.
The circadian clock shapes immune function, yet its influence on infection outcomes is only beginning to be understood. This review highlights how circadian timing alters host responses to the bacterial pathogens Salmonella enterica, Listeria monocytogenes, and Streptococcus pneumoniae revealing that the effectiveness of immune defense depends not only

The Influence of Gold Nanoparticles Addition on Sugarcane Leaves-Derived Silica Xerogel Catalyst for the Production of Biodiesel

Gels
Biodiesel was produced via transesterification of canola oil in the presence of a silica xerogel catalyst with deposited gold nanoparticles. The silica-gold catalyst was produced in situ, where gold metal was added to a sodium silicate solution ...

Enhanced stability for oxygen reduction reaction of supported platinum-based catalyst with Fe-N doped activated carbon as carbon support

Cailiao gongcheng, 2022
Modification and doping of carbon support are the main ways to improve the performance of the platinum-based catalyst for proton exchange membrane fuel cell. FeN-BP.Iron and nitrogen(FeN) co-doped activated carbon (Black Pearl 2000, BP) as a support, was

Disordered but rhythmic—the role of intrinsic protein disorder in eukaryotic circadian timing

FEBS Letters, EarlyView.
Unstructured domains known as intrinsically disordered regions (IDRs) are present in nearly every part of the eukaryotic core circadian oscillator. IDRs enable many diverse inter‐ and intramolecular interactions that support clock function. IDR conformations are highly tunable by post‐translational modifications and environmental conditions, which ...

Morphology of supported polymer electrolyte ultra-thin films: a numerical study

, 2015
Morphology of polymer electrolytes membranes (PEM), e.g., Nafion, inside PEM fuel cell catalyst layers has significant impact on the electrochemical activity and transport phenomena that determine cell performance.
