Strong localization of electrons in quasi-one-dimensional conductors

, 1998
We report on the experimental study of electron transport in sub-micron-wide ''wires'' fabricated from Si $\delta $-doped GaAs. These quasi-one-dimensional (Q1D) conductors demonstrate the crossover from weak to strong localization with decreasing the ...

Peptide‐based ligand antagonists block a Vibrio cholerae adhesin

FEBS Letters, EarlyView.
The structure of a peptide‐binding domain of the Vibrio cholerae adhesin FrhA was solved by X‐ray crystallography, revealing how the inhibitory peptide AGYTD binds tightly at its Ca2+‐coordinated pocket. Structure‐guided design incorporating D‐amino acids enhanced binding affinity, providing a foundation for developing anti‐adhesion therapeutics ...

Intramolecular Versus Intermolecular Diels–Alder Reactions: Insights from Molecular Electron Density Theory

Molecules
The intramolecular Diels–Alder (IMDA) reactions of four substituted deca-1,3,9-trienes and one N-methyleneocta-5,7-dien-1-aminium with different electrophilic/nucleophilic activations have been studied within the Molecular Electron Density Theory (MEDT ...

Thermoelectric properties of Mott insulator with correlated hopping at microdoping

Condensed Matter Physics, 2020
An influence of the localization of itinerant electrons induced by correlated hopping on the electronic charge and heat transport is discussed for the lightly doped Mott insulator phase of the Falicov-Kimball model.

Interplay between circadian and other transcription factors—Implications for cycling transcriptome reprogramming

FEBS Letters, EarlyView.
This perspective highlights emerging insights into how the circadian transcription factor CLOCK:BMAL1 regulates chromatin architecture, cooperates with other transcription factors, and coordinates enhancer dynamics. We propose an updated framework for how circadian transcription factors operate within dynamic and multifactorial chromatin landscapes ...

Plasmonic hot electron transport drives nano-localized chemistry

Nature Communications, 2017
Quantitative understanding of the spatial localization of hot carriers has been elusive. Here Corteset al. spatially map hot-electron-driven reduction chemistry with 15 nm resolution as a function of time and electromagnetic field polarization for ...

Analysis of Relationship Between Some Disazo Dyes Derived from 2,4-Dihydroxyquinoline and Its Anticancer and DNA Binding Properties by Density Functional Theory

Süleyman Demirel Üniversitesi Fen-Edebiyat Fakültesi Fen Dergisi, 2021
It was studied some physical and chemical properties of 2,4-dihydroxy quinoline derivative diazo dyes by theoretical methods. Six different solvents were used to determine the solvatochromic behavior and absorption of the compounds, and the experimental ...

Polaron formation for a non-local electron-phonon coupling: A variational wave-function study

, 2004
We introduce a variational wave-function to study the polaron formation when the electronic transfer integral depends on the relative displacement between nearest-neighbor sites giving rise to a non-local electron-phonon coupling with optical phonon ...

Disordered but rhythmic—the role of intrinsic protein disorder in eukaryotic circadian timing

FEBS Letters, EarlyView.
Unstructured domains known as intrinsically disordered regions (IDRs) are present in nearly every part of the eukaryotic core circadian oscillator. IDRs enable many diverse inter‐ and intramolecular interactions that support clock function. IDR conformations are highly tunable by post‐translational modifications and environmental conditions, which ...

Orbital localization criterion as a complementary tool in the bonding analysis by means of electron localization function: study of the Si(n)(BH)(5-n)(2-) (n = 0-5) clusters.

Journal of Physical Chemistry A, 2013
A recently proposed molecular orbital localization procedure, based on the electron localization function (ELF) technique, has been used to describe chemical bonding in the cluster series Sin(BH)(5-n)(2-) (n = 0-5).
