Electron-Electron Interactions in Artificial Graphene

Physical Review Letters, 2012
Recent advances in the creation and modulation of graphene-like systems are introducing a science of "designer Dirac materials". In its original definition, artificial graphene is a man-made nanostructure that consists of identical potential wells (quantum dots) arranged in a adjustable honeycomb lattice in the two-dimensional electron gas.

Electron-Electron Interactions and the Hall-Insulator

, 1994
Using the Kubo formula, we show explicitly that a non-interacting electron system can not behave like a Hall-insulator, {\it ie.,} a DC resistivity matrix $\rho_{xx}\rightarrow\infty$ and $\rho_{xy}=$finite in the zero temperature limit, as has been ...

Density-functional method for nonequilibrium electron transport [PDF]

, 2001
We describe an ab initio method for calculating the electronic structure, electronic transport, and forces acting on the atoms, for atomic scale systems connected to semi-infinite electrodes and with an applied voltage bias.

Elucidating prognostic significance of purine metabolism in colorectal cancer through integrating data from transcriptomic, immunohistochemical, and single‐cell RNA sequencing analysis

Molecular Oncology, EarlyView.
Low expression of five purine metabolism‐related genes (ADSL, APRT, ADCY3, NME3, NME6) was correlated with poor survival in colorectal cancer. Immunohistochemistry analysis showed that low NME3 (early stage) and low ADSL/NME6 (late stage) levels were associated with high risk.

Effective electron-electron and electron-phonon interactions in the Hubbard-Holstein model

, 2006
We investigate the interplay between the electron-electron and the electron-phonon interaction in the Hubbard-Holstein model. We implement the flow-equation method to investigate within this model the effect of correlation on the electron-phonon ...

Mapping Hsp104 interactions using cross‐linking mass spectrometry

FEBS Open Bio, Volume 15, Issue 6, Page 922-939, June 2025.
This study examines how cross‐linking mass spectrometry can be utilized to analyze ATP‐induced conformational changes in Hsp104 and its interactions with substrates. We developed an analytical pipeline to distinguish between intra‐ and inter‐subunit contacts within the hexameric homo‐oligomer and discovered contacts between Hsp104 and a selected ...

ДОСЛІДЖЕННЯ ВПЛИВУ ХАОТИЧНОГО СТРУМУ ЕЛЕКТРОНІВ НА ПАРАМЕТРИ ЕЛЕКТРИЧНОГО ПОЛЯ У ПРИАНОДНІЙ ЗОНІ РОЗРЯДУ

Elektrotehnìka ta Elektroenergetika, 2010
Розглянуто вплив співвідношення густини розрядного та хаотичного електронних струмів на падіння потенціалу у дифузійній зоні прианодної області. Виконано аналіз впливу вимушеної конвекції на умови існування стійкого дифузного розряду на поверхні анода.

Alkane biosynthesis gene expression and its increased production in recombinant cyanobacteria

FEBS Open Bio, Volume 15, Issue 6, Page 949-962, June 2025.
The transcription and mRNA structures of the alkane biosynthesis genes ado/aar were analysed in the representative cyanobacteria PCC 6803 and SK1‐2‐1, which produce C17H36 and C15H32, respectively. PCC 6803 transconjugants carrying these genes showed a 1.8‐ to 2.3‐fold increase in C17H36 production.

Electron capture in GaAs quantum wells via electron-electron and optic phonon scattering

, 1995
Electron capture times in a separate confinement quantum well (QW) structure with finite electron density are calculated for electron-electron (e-e) and electron-polar optic phonon (e-pop) scattering.

Mitochondrial electron transport chain, ROS generation and uncoupling (Review)

International Journal of Molecular Medicine, 2019
The mammalian mitochondrial electron transport chain (ETC) includes complexes I-IV, as well as the electron transporters ubiquinone and cytochrome c. There are two electron transport pathways in the ETC: Complex I/III/IV, with NADH as the substrate and ...
