Effect of Catalyst and Catalyst Layer Composition on Catalyst Support Durability [PDF]
Journal of The Electrochemical Society, 2021 Polymer electrolyte membrane fuel cells (PEMFCs) are efficient, zero-emission engines for the automotive sector. However, cost and durability are major barriers for the commercialization of PEMFCs. Degradation of the carbon support in the cathode catalyst layer due to high potential excursions caused by unmitigated events like H2 starvation, or start ...

Computational catalyst discovery: Active classification through myopic multiscale sampling [PDF]
, 2021 The recent boom in computational chemistry has enabled several projects aimed at discovering useful materials or catalysts. We acknowledge and address two recurring issues in the field of computational catalyst discovery. First, calculating macro-scale catalyst properties is not straight-forward when using ensembles of atomic-scale calculations (e.g ...

Nonstoquastic catalyst for bifurcation-based quantum annealing of ferromagnetic $p$-spin model [PDF]
Phys. Rev. A 107, 052401 (2023), 2022 Introducing a nonstoquastic catalyst is a promising avenue to improve quantum annealing with the transverse field. In the present paper, we propose a nonstoquastic catalyst for bifurcation-based quantum annealing described by the spin-1 operators to improve the efficiency of a ground-state search. To investigate the effect of the nonstoquastic catalyst,

Catalyst-Assisted Probabilistic Coherence Distillation for Mixed States [PDF]
PRA 101,012313(2020), 2020 The remarkable phenomenon of catalyst tells us that adding a catalyst could help state transformation. In this paper, we consider the problem of catalyst-assisted probabilistic coherence distillation for mixed states under strictly incoherent operations.

Correlation in Catalysts Enables Arbitrary Manipulation of Quantum Coherence [PDF]
Phys. Rev. Lett. 128, 240501 (2022), 2021 Quantum resource manipulation may include an ancillary state called a catalyst, which aids the transformation while restoring its original form at the end, and characterizing the enhancement enabled by catalysts is essential to reveal the ultimate manipulability of the precious resource quantity of interest.

DNA Hybridization Catalysts and Catalyst Circuits [PDF]
, 2005 Practically all of life's molecular processes, from chemical synthesis to replication, involve enzymes that carry out their functions through the catalysis of metastable fuels into waste products. Catalytic control of reaction rates will prove to be as useful and ubiquitous in DNA nanotechnology as it is in biology. Here we present experimental results

, 2009 The use of N-heterocyclic carbenes as catalysts for organic transformations has received increased attention in the past 10 years. A discussion of catalyst development and nucleophilic characteristics precedes a description of recent advancements and new reactions using N-heterocyclic carbenes in catalysis.
