Entanglement catalysis for quantum states and noisy channels
Many applications of the emerging quantum technologies, such as quantum teleportation and quantum key distribution, require singlets, maximally entangled states of two quantum bits. It is thus of utmost importance to develop optimal procedures for establishing singlets between remote parties. As has been shown very recently, singlets can be obtained from other quantum states by using a quantum catalyst, an entangled quantum system which is not changed in the procedure. In this work we take this…

Oxygen Reduction Reaction on Single-Atom Catalysts From Density Functional Theory Calculations Combined with an Implicit Solvation Model
We present a density functional theory study of the oxygen reduction reaction (ORR) on a single atom catalyst embedded in graphene, namely, TM-N$_{4}$-C (TM = Fe and Co), using the effective screening medium method combined with the reference interaction site model (ESM-RISM). It was found that Fe-N$_{4}$-C and Co-N$_{4}$-C show comparable ORR activities from the constant electrode potential simulations, in contrast to the results obtained using the constant (neutral) charge simulation, in whic…

Highly dispersed Ru nanoparticles anchored on NiAl layered double oxides catalyst for selective hydrodeoxygenation of vanillin
The hydrodeoxygenation (HDO) of lignin-derived feedstocks into value-added chemicals with high efficiency and selectivity is desirable for the utilization of biomass resource. The complex oxygen-containing groups of lignin-derived substance result in the challenge of the low selectivity toward the required product. In this work, highly dispersed Ru nanoparticles anchored on Ni3Al1 layered double oxides (LDOs) catalyst derived from NiAl layered double hydroxides (LDHs) with flower-shaped morphol…

Growth of metal catalyst nanoparticles in hydrocarbon-rich atmosphere of arc discharge for synthesis of carbon nanotubes
A direct current (DC) arc discharge is a widely used method for industrial-scale production of single-walled carbon nanotubes (SWCNT). A high-selectivity synthesis of SWCNT requires ultra-fine, typically a few nanometers in diameter, catalyst particles, which is challenging to achieve in harsh arc environments involving high temperatures, ablation of electrode materials, convection, and instabilities. Here, we explore how the size of metal catalyst nanoparticles is affected by a hydrocarbon-ric…

Chemically reactive thin films: dynamics and stability
Catalyst particles or complexes suspended in liquid films can trigger chemical reactions leading to inhomogeneous concentrations of reactants and products in the film. We demonstrate that the sensitivity of the liquid film's gas-liquid surface tension to these inhomogeneous concentrations strongly impacts the film stability. Using linear stability analysis, we identify novel scenarios in which the film can be either stabilized or destabilized by the reactions. Furthermore, we find so far unreve…

Adsorption energy, a reactivity descriptor, should be accurately assessed for efficient catalyst screening. This evaluation requires determining the lowest energy across various adsorption configurations on the catalytic surface.

Topological iron silicide with H* intermediate modulated surface for efficient electrocatalytic hydrogenation of nitrobenzene in neutral medium
Electrocatalytic hydrogenation of nitrobenzene (Ph-NO2) reaction (EHNR) has been considered as a potential alternative to the traditional thermocatalytic process in the production of high-value aniline (Ph-NH2). However, due to the absence of robust catalyst and low surface H* coverage, the EHNR faces the challenges of undesired performance and indetermined mechanism. Herein, we construct a type of noble-metal free topological FeSi (M-FeSi) materials through a solvent-free microwave strategy fo…

Reconstruction algorithms for source term recovery from dynamical samples in catalyst models
This paper investigates the problem of recovering source terms in abstract initial value problems (IVP) commonly used to model various scientific phenomena in physics, chemistry, economics, and other fields. We consider source terms of the form $F=h+η$, where $η$ is a Lipschitz continuous background source. The primary objective is to estimate the unknown parameters of non-instantaneous sources $h(t)=\sum\limits_{j=0}^M h_je^{-ρ_j(t-t_j)}χ_{[t_j,\infty)}(t)$, such as the decay rates, initia…
