Atomic Size Misfit for Electrocatalytic Small Molecule Activation

open access: yesAdvanced Functional Materials, EarlyView.
This review explores the application and mechanisms of atomic size misfit in catalysis for small molecule activation, focusing on how structural defects and electronic properties can effectively lower the energy barriers of chemical bonds in molecules like H2O, CO2, and N2.

Adaptive Gibbs samplers [PDF]

open access: yes, 2010
We consider various versions of adaptive Gibbs and Metropolis- within-Gibbs samplers, which update their selection probabilities (and perhaps also their proposal distributions) on the fly during a run, by learning as they go in an attempt to optimise

Non Thermal‐Driven Photocatalytic Ammonia Decomposition at Near‐Room Temperature on a Plasmonic Nanocone Array

open access: yesAdvanced Functional Materials, EarlyView.
Plasmonic photocatalytic ammonia decomposition occurs at near‐room temperature on a plasmonic Au nanocone array under visible light illumination. The nanostructure efficiently harnesses plasmonic modes, leading to increased reaction rates upon plasmon decay.

Taxonomy of the genus Ehrharta (Poaceae) in southern Africa: the Setacea group

open access: yesBothalia: African Biodiversity & Conservation, 1987
The Setacea species group in the genus Ehrharta Thunb. is differentiated morphologically by the short first sterile lemma and by inflorescences of fewer than 20 spikelets.

Asymptotic entropy of the Gibbs state of complex networks

open access: yesScientific Reports, 2021
In this work we study the entropy of the Gibbs state corresponding to a graph. The Gibbs state is obtained from the Laplacian, normalized Laplacian or adjacency matrices associated with a graph.

Modeling income distribution: An econophysics approach

open access: yesMathematical Biosciences and Engineering, 2023
This study aims to develop appropriate models for income distribution in Iran using the econophysics approach for the 2006–2018 period. For this purpose, the three improved distributions of the Pareto, Lognormal, and Gibbs-Boltzmann distributions are ...

2D Multifunctional Spin‐Orbit Coupled Dirac Nodal Line Materials

open access: yesAdvanced Functional Materials, EarlyView.
A total of 473 nonmagnetic and antiferromagnetic 2D spin‐orbit coupled Dirac nodal line materials are screened, spanning 5 layer groups and 12 magnetic space groups. Furthermore, it integrates their topological properties with electride, multiferroic, and magnetic characteristics, revealing unique systems with expanded functionalities and promising ...

The role of MRI in applying the 3Rs to non-human primate neuroscience

open access: yesNeuroImage, 2021
Magnetic resonance imaging is playing a significant role in applying the 3Rs to neuroscience studies using non-human primates. MRI scans are contributing to refinement by enhancing the selection and assignment of animals, guiding the manufacture of ...

Z‐Scheme Water Splitting Systems Based on Solid‐State Electron Conductors

open access: yesAdvanced Functional Materials, EarlyView.
This review examines the latest advances in Z‐scheme overall water splitting (OWS) systems for solar hydrogen production. These systems consist of suspended or immobilized hydrogen evolution photocatalysts (HEPs) and oxygen evolution photocatalysts (OEPs).

Gibbs paradox and it’s solution

open access: yesИзвестия высших учебных заведений: Проблемы энергетики, 2017
The article deals with the classical solution of the Gibbs paradox, on the basis of which and experimentally verified the facts in the presence of the chemical energy of real gases and gases with properties approaching the ideal gases promoted the ...
