Relativistic quantum dynamics in strong fields: Photon emission from heavy, few-electron ions

open access: yes, 2004
Recent progress in the study of the photon emission from highly-charged heavy ions is reviewed. These investigations show that high-$Z$ ions provide a unique tool for improving the understanding of the electron-electron and electron-photon interaction in

Dynamics of Coordinated Phosphonate Group Directly Observed by 17O‐NMR in Lanthanide(iii) Complexes of a Mono(ethyl phosphonate) DOTA Analogue

open access: yesChemistry – A European Journal, Volume 30, Issue 36, June 25, 2024.
Dynamics of mutual exchange of coordinated and non‐coordinated oxygen atoms on phosphate anion analogue was measured for the first time. It proceeds through a sterically demanding four‐membered κ2‐O2P chelate. Its energy barrier steeply increases for smaller Ln(III) ions and is accessible only in more flexible TSA isomers of large Ln(III) ions ...

Accessing the molecular frame through strong-field alignment of distributions of gas phase molecules [PDF]

open access: yes, 2018
A rationale for creating highly aligned distributions of molecules is that it enables vector properties referenced to molecule-fixed axes (the molecular frame) to be determined.

Quantum entanglement in strong-field ionization [PDF]

open access: yes, 2017
We investigate the time-evolution of quantum entanglement between an electron, liberated by a strong few-cycle laser pulse, and its parent ion-core. Since the standard procedure is numerically prohibitive in this case, we propose a novel way to quantify ...

Deep Eutectic Solvents: The Organic Reaction Medium of the Century [PDF]

open access: yes, 2016
This microreview summarizes the use of deep eutectic solvents (DESs) and related melts in organic synthesis. Solvents of this type combine the great advantages of other proposed environmentally benign alternative solvents, such as low toxicity, high ...

Microwave-assisted synthesis of α-aminophosphonates with sterically demanding α-aryl substituents [PDF]

open access: yes, 2020
A series of N-benzhydryl protected α-aminophosphonates with α-phenyl, α-(1-naphtyl), α-(9-anthryl) or α-(1-pyrenyl) substituents was synthesized by the Kabachnik–Fields condensation of diphenylmethylamine (benzhydrylamine), the corresponding aryl ...

Quantum coherent control of the photo\-electron angular distribution in bichromatic ionization of atomic neon

open access: yes, 2017
We investigate the coherent control of the photo\-electron angular distribution in bichromatic atomic ionization. Neon is selected as target since it is one of the most popular systems in current gas-phase experiments with free-electron lasers (FELSs ...

On the discovery and development of tandem 1,4- and 1,2-addition of phosphites to 1-azadienes [PDF]

open access: yes, 2014
Over the past 15 years we have developed a one-step protocol for the synthesis of 3-phosphonylated aminophosphonates from alpha,beta-unsaturated imines through tandem 1,4-1,2-phosphite addition.

Strong-field physics with mid-IR fields [PDF]

open access: yes, 2015
Strong-field physics is currently experiencing a shift towards the use of mid-IR driving wavelengths. This is because they permit conducting experiments unambiguously in the quasi-static regime and enable exploiting the effects related to ponderomotive ...

'Maybe it is prejudice ... but it is NOT racism': Negotiating racism in discussion forums about Gypsies [PDF]

open access: yes, 2014
This article addresses the ways in which opposition towards Gypsies is debated, with particular regard to whether or not this opposition constitutes racism or prejudice towards a group shown to be vulnerable and subject to discrimination.
