Disentangling the size-dependent geometric and electronic effects of palladium nanocatalysts beyond selectivity

Science Advances, 2019
Site-selective blocking by ALD disentangles the geometric and electronic effects of catalysts beyond the selectivity volcano. The prominent size effect of metal nanoparticles shapes decisively nanocatalysis, but entanglement of the corresponding ...

Microbiome−host proteostasis crosstalk—An emerging perspective on mechanisms and interventions toward healthy longevity

FEBS Letters, EarlyView.
Proteostasis and the gut microbiota play a key role in shaping host physiology. Microbiota‐derived metabolites, vitamins, and RNA modulate host proteostasis. Findings from model systems, including C. elegans, indicate microbes can either stabilize or disrupt host proteostasis.

Glycerol Electrooxidation at Structured Nickel Electrodes and the Effect of Geometry on the Selectivity of Product

ChemElectroChem
Electrocatalytic selectivity is generally explained in terms of atomic‐scale properties, i.e., active sites, overlooking the impact of macroscopic electrode geometry and structure, which affect the macroscopic mass transport.

How cations affect the electric double layer and the rates and selectivity of electrocatalytic processes.

Journal of Chemical Physics, 2019
Electrocatalysis is central to the production of renewable fuels and high-value commodity chemicals. The electrolyte and the electrode together determine the catalytic properties of the liquid/solid interface.

From mice to humans—divergent strategies for intestinal homeostasis and regeneration

FEBS Letters, EarlyView.
Recent advances such as organoid genome editing, xenotransplantation, imaging, and whole‐genome sequencing have enabled direct studies of human intestinal stem cells (ISCs). These studies reveal species‐specific features, including slower ISC proliferation, distinct injury responses, slower somatic mutation accumulation in humans, and an inverse ...

Phosphoinositides and inositol phosphates as molecular glues

FEBS Letters, EarlyView.
Inositol phosphates (IPs) and phosphoinositides (PIPs) regulate diverse eukaryotic processes. Beyond recruiting signaling proteins or acting as structural cofactors, recent studies suggest they mediate protein–protein interactions as natural molecular glues.

Structural insights and therapeutic targets in Acinetobacter baumannii capsule biosynthesis

FEBS Letters, EarlyView.
Hypervirulent KL49 A. baumannii's capsular polysaccharide contains the nonulosonic acid 8‐epi‐Leg5,7Ac2, synthesized by epimerization via ElaA, ElaB, and ElaC. Crystal structures of ElaA, ElaB, and ElaC reveal their role in CMP‐Leg5,7Ac2 synthesis and regioselective C8 epimerization.
