Achievement of Transition Metal Chalcogenides/Oxides in Hydrogen Production by Seawater Electrolysis

open access: yesEcoEnergy, EarlyView.
Transition metal chalcogenides (TMCs)/oxides have shown great application potential in seawater splitting for hydrogen generation due to their adjustable electronic properties, abundant active sites, and excellent catalytic performance. ABSTRACT Under the impetus of global “dual carbon” goals, green hydrogen has become a key component of the future ...

Hydride Materials for Advanced Electrochemical Energy Storage: Progress and Perspectives

open access: yesEcoEnergy, EarlyView.
Hydrides are emerging as functional materials for low‐carbon electrochemical energy storage. Complex hydrides provide polyanionic electrolyte frameworks for all‐solid‐state, Li–S, and multivalent batteries; hydride ion conductors enable H− transport for emerging hydride‐based cells; and metal hydrides offer established electrode chemistries for Ni–MH ...

General features of the dissociative recombination of polyatomic molecules

open access: yesEPJ Web of Conferences, 2015
We discuss some aspects of a simple expression for the low-energy dissociative recombination cross section that applies when the recombination process is dominated by the indirect mechanism. In most previous applications, this expression has been applied

Scaling turbulence drives the general circulation

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
The NOAA Gulfstream SP4, which deployed the GPS dropsondes over the NE Pacific Ocean as part of the Winter Storms Project during the January–March periods of 2004, 2005 and 2006. Abstract Statistical multifractal analysis of airborne and dropsonde observations is used to show that persistence of velocity after molecular collisions breaks the continuous

Structure and Properties of Simple and Aggregate Systems by Circular Dichroism Spectroscopy [PDF]

open access: yes, 2013
This thesis deals with the investigation of structural properties of many different systems via Electronic Circular Dichroism (ECD). The interpretation of experimental data has been carried out mainly with quantum-chemistry methods, such as Density ...

First-principles quantum dynamical theory for the dissociative chemisorption of H2O on rigid Cu(111)

open access: yesNature Communications, 2016
Dissociative chemisorption dynamics of polyatomic molecules on surfaces are still challenging to probe quantitatively. Here, the authors report the 9-dimensional quantum dynamics of H2O dissociative chemisorption on Cu(111), with the highest level of ...

Reactivity of Oxidized Porous Silicon with Calcium Ion in Aqueous Media: Stability, pH Behavior, and Host‐Guest Strategies

open access: yesSmall, EarlyView.
Oxidized porous silicon, composed of an elemental silicon porous skeleton coated with a silica shell, reacts with aqueous Ca2+ to generate a mixed silica–calcium silicate matrix that is remarkably efficient at trapping small molecules. With an emphasis on the engineering of controlled‐release drug delivery systems, this study identifies the factors ...

UV-Driven Harmonic Generation for Time-Resolved Photoelectron Spectroscopy of Polyatomic Molecules

open access: yesApplied Sciences, 2018
A single-order harmonic pulse in the vacuum-ultraviolet (VUV) is highly desirable for time-resolved photoelectron spectroscopy (TRPES) of polyatomic molecules.
