Mapping an electron wave function by a local electron scattering probe

New Journal of Physics, 2015
A technique is developed which allows for the detailed mapping of the electronic wave function in two-dimensional electron gases with low-temperature mobilities up to 15E6 cm^2/Vs. Thin ("delta") layers of aluminium are placed into the regions where the electrons reside. This causes electron scattering which depends very locally on the amplitude of the

Chiral separation of chloroalkanes with the chromatographic column onboard Martian rovers

FEBS Letters, EarlyView.
Computer image of the Rosalind Franklin Rover of ESA's ExoMars mission. ExoMars is scheduled to land on planet Mars in Oxia Planum in 2029. This area represents an interesting spot to look for biosignatures. Investigations of ExoMars include measurement on molecular chirality. We show that chiral chloroalkanes, that have been identified on Mars, can be

Bonding Analysis of Hydrogenated Lithium Clusters Using the Electron Localization Function

, 2016
The electron localization function (ELF) has been used to study the bonding characteristics of the hydrogenated lithium clusters. The analysis of the ELF clearly confirmed the hypothesis that each hydrogen atom added to the lithium cluster completely ...

Chemical Bonding in Excited States: Electron Localization, Delocalization and Statistics in Real Space [PDF]

, 2019
In this contribution, we continue with our enterprise regarding the systematization of chemical bonding in excited states. We show how real space electron localization and delocalization measures, coupled to the statistical analysis of electron number ...

Artificial molecular machines and motors—Design and control of nanoscale motion

FEBS Letters, EarlyView.
Molecules are constantly moving because of thermal fluctuations, but random motion alone cannot be exploited to perform directional tasks. Artificial molecular machines use chemical, electrical, or light energy to bias this motion. Molecular shuttles, rotary motors, and supramolecular pumps illustrate how nanoscale movement can be controlled and ...

APEX Fingerprinting Reveals the Subcellular Localization of Proteins of Interest

Cell Reports, 2016
Deciphering the sub-compartmental location of a given protein of interest may help explain its physiological function, but it can be challenging to do using optical or biochemical methods. Imaging with electron microscopy (EM) can provide highly resolved

Hydrogen detachment driven by a repulsive 1πσ* state – an electron localization function study of 3-amino-1,2,4-triazole

, 2018
Electron localization function analysis reveals the details of a charge induced hydrogen detachment mechanism of 3-amino-1,2,4-triazole, identified recently as responsible for phototautomerization of the molecule.

Smaller is better: nanobodies meet NMR

FEBS Letters, EarlyView.
Nanobodies are single‐domain antigen‐binding fragments derived from camelid heavy chain antibodies. Their small size, high stability, and exceptional specificity make nanobodies uniquely useful probes for NMR studies of protein dynamics, transient conformational states, and protein–protein interactions.

Quantum Entanglement and Shannon Information Entropy for the Doubly Excited Resonance State in Positronium Negative Ion

Atoms, 2015
In the present work, we report an investigation on quantum entanglement in the doubly excited 2s2 1Se resonance state of the positronium negative ion by using highly correlated Hylleraas type wave functions, determined by calculation of the density of ...

Electron localization function for two-dimensional systems [PDF]

Physical Review B, 2008
The concept of the electron localization function (ELF) is extended to two-dimensional (2D) electron systems. We show that the topological properties of the ELF in 2D are considerably simpler than in molecules studied previously. We compute the ELF and demonstrate its usefulness for various physical 2D systems, focusing on semiconductor quantum dots ...
