Effects of Ink Formulation on the Structure and Performance of PGM-Free Catalyst Layer in PEMFCs

, 2021
Platinum group metal (PGM) catalysts are the major electrocatalysts for oxygen reduction reaction (ORR) in the polymer electrolyte membrane fuel cells (PEMFCs). The cost becomes unaffordable if the PEMFC is in massive application.

Durable Fuel Cell Cathode Enabled by Pt Embedded Nanoscale Carbon Network via a Scalable Process

Carbon Energy, EarlyView.
Platinum nanoparticles embedded nanoscale carbon network (Pt‐e‐Cn) are developed via a scalable flame spray pyrolysis process. Proton exchange membrane fuel cells (PEMFC) employing mesoporous Pt‐e‐Cn cathode electrocatalysts exhibit exceptional durability without compromising performance.

Alkene Hydrogenation by a Cationic, Nine‐Coordinate Molybdenum(VI) Pentahydride Catalyst

Chemistry – A European Journal, EarlyView.
While late 3d metals dominate efforts to replace precious metals in homogeneous hydrogenation, molybdenum has remained largely ignored. This work reveals that a nine‐coordinate pentahydrido molybdenum complex can hydrogenate a broad range of alkenes efficiently, demonstrating that early‐metal polyhydrides can serve as genuine catalysts rather than mere

How Amino Acids Intercalate in CaFe Layered Double Hydroxides: A Combined RIXS and NEXAFS Study

ChemPhysChem, Volume 26, Issue 6, March 15, 2025.
Intercalation of amino acids in layered double hydroxides offers a road to functional (bio)catalysts. With resonant soft x‐ray spectroscopy we probe the electronic structure of these systems and observe activation and passivation of electronic states as well as bond formation between the amino acid and the LDH upon intercalation.

Unraveling the role of surface mucus-binding protein and pili in muco-adhesion of Lactococcus lactis.

PLoS ONE, 2013
Adhesion of bacteria to mucus may favor their persistence within the gut and their beneficial effects to the host. Interactions between pig gastric mucin (PGM) and a natural isolate of Lactococcus lactis (TIL448) were measured at the single-cell scale ...

Going from Pt to PGM‐free Catalysts: Effects of Ink Compositions on PEM Water Electrolysis

ChemPhysChem, Volume 26, Issue 6, March 15, 2025.
Optimisation of cathode ink formulations regarding the ratio between catalyst, carbon and binder results in a boost in PEM water electrolysis performance. The optimisation can be transferred from pentlandites to platinum and selenide catalysts, wherein the metal chalcogenides show a stronger performance enhancement.

Development and validation of a genetic probability for venous thromboembolism

Research and Practice in Thrombosis and Haemostasis
Background: Factor V Leiden (FVL) and prothrombin gene mutations (PGMs), as well as recently developed polygenic scores (PGSs), have been consistently associated with venous thromboembolism (VTE) risk in European ancestry populations.

Particle Gaussian Mixture (PGM) Filters

CoRR, 2016
Recursive estimation of nonlinear dynamical systems is an important problem that arises in several engineering applications. Consistent and accurate propagation of uncertainties is important to ensuring good estimation performance. It is well known that the posterior state estimates in nonlinear problems may assume non-Gaussian multimodal densities. In
