Hydrogen–vacancy–dislocation interactions in α-Fe

William Curtin, Ali Tehranchi, Xi Zhang

Atomistic simulations of the interactions between dislocations, hydrogen atoms, and vacancies are studied to assess the viability of a recently proposed mechanism for the formation of nanoscale voids in Fe-based steels in the presence of hydrogen. Quantum- ...

Calorimetric and Spectroscopic Studies on the Solvation Energetics for H2 Storage in the CO2/HCOOH System

Gabor Laurenczy, Cornel Fink

Solvents play a crucial role in many chemical reactions and additives can be used to shift the reaction equilibrium. Herein we study the enthalpy of mixing for selected solvents (aqueous, organic) and basic additives (amines, aqueous KOH) when mixed with f ...

Surface Reactions are Crucial for Energy Storage

Philippe Mauron, Shunsuke Kato, Elsa Callini

Reactions between gas molecules, e.g. H-2 and CO2 and solids take place at the surface. The electronic states and the local geometry of the atomic arrangement determine the energy of the adsorbate, i.e. the initial molecule and the transition state. Here w ...

Solar hydrogen reaching maturity

Sophia Haussener, Mikaël Dumortier

Increasingly vast research efforts are devoted to the development of materials and processes for solar hydrogen production by light-driven dissociation of water into oxygen and hydrogen. Storage of solar energy in chemical bonds resolves the issues associa ...

Closing the pressure gap in x-ray photoelectron spectroscopy by membrane hydrogenation

Comprehensive studies of gas-solid reactions require the in-situ interaction of the gas at a pressure beyond the operating pressure of ultrahigh vacuum (UHV) X-ray photoelectron spectroscopy (XPS). The recent progress of near ambient pressure XPS allows to ...

Study of hydrogen storage and compression

Nicolas Jean Matet

The goal of this rapport is to present an overview of the different hydrogen storage technologies, currently available for industrial application or at earlier stages of development. In order to identify the water and mechanical work requirements for compr ...

Direct Carbon Dioxide Hydrogenation into Formic Acid in Acidic Media

Séverine Joëlle Moret

A major challenge in the face of increasing global energy demand is the development of alternative environmentally friendly and renewable energy resources. Hydrogen is an excellent energy carrier, but has drawbacks in storage density and is dangerous to ha ...

Artificial Photosynthesis at Soft Interfaces

Hubert Girault, Fernando Cortes Salazar, Manuel Alejandro Méndez Agudelo, Peiyu Ge, Haiqiang Deng, Imren Hatay, Patrick Voyame, Zahra Nazemi

The concept of artificial photosynthesis at a polarised liquid membrane is presented. It includes two photosystems, one at each interface for the hydrogen and oxygen evolution respectively. Both reactions involve proton coupled electron transfer reactions, ...

Mobility and dynamics in the complex hydrides LiAlH4 and LiBH4

Pascal Martelli

The dynamics and bonding of the complex hydrides LiBH4 and LiAlH4 have been investigated by vibrational spectroscopy. The combination of infrared, Raman, and inelastic neutron scattering (INS) spectroscopies on hydrided and deuterided samples reveals a com ...

A multifaceted approach to hydrogen storage

Bengt Kasemo

The widespread adoption of hydrogen as an energy carrier could bring significant benefits, but only if a number of currently intractable problems can be overcome. Not the least of these is the problem of storage, particularly when aimed at use onboard ligh ...
