Correlated electrons systems on the Apollonian network [PDF]

, 2006
Strongly correlated electrons on an Apollonian network are studied using the Hubbard model. Ground-state and thermodynamic properties, including specific heat, magnetic susceptibility, spin-spin correlation function, double occupancy and one-electron ...

Linking neurogenesis, oligodendrogenesis, and myelination defects to neurodevelopmental disruption in primary mitochondrial disorders

FEBS Letters, EarlyView.
Mitochondrial remodeling shapes neural and glial lineage progression by matching metabolic supply with demand. Elevated OXPHOS supports differentiation and myelin formation, while myelin compaction lowers mitochondrial dependence, revealing mitochondria as key drivers of developmental energy adaptation.

Direct Electron Transfer Response of Superoxide Dismutase on a Graphene-Based Modified Electrode

International Journal of Electrochemical Science, 2015
Single stranded DNA (ssDNA)/graphene (GR) nanocomposites were prepared by a chemical route and cast on basal plane graphite (BPG) electrode to construct an ssDNA/GR modified electrode.

Low-energy limit of the three-band model for electrons in a CuO$_{2}$ plane

, 1993
The three-band model with the O-O direct hopping near to unit filling is considered. We present the general procedure of reduction of this model to the low-energy limit.

Organizing the interface—Plasma membrane architecture and receptor dynamics in virus‐cell interactions

FEBS Letters, EarlyView.
Plasma membranes contain dynamic nanoscale domains that organize lipids and receptors. Because viruses operate at similar scales, this architecture shapes early infection steps, including attachment, receptor engagement, and entry. Using influenza A virus and HIV‐1 as examples, we highlight how receptor nanoclusters, multivalent glycan interactions ...

Enzymatic Direct Electron Transfer at Ascorbate Oxidase-modified Gold Electrode Prepared by One-step Galvanostatic Method

International Journal of Electrochemical Science, 2012
A one-step enzyme immobilization by galvanostatic method at gold electrode was applied to achieve direct electron transfer (DET) of ascorbate oxidase from Acremonium sp. (ASOM).

Artificial photosynthetic reaction centers coupled to light-harvesting antennas

, 2010
We analyze a theoretical model for energy and electron transfer in an artificial photosynthetic system. The photosystem consists of a molecular triad (i.e., with a donor, a photosensitive unit, and an acceptor) coupled to four accessory light-harvesting ...

Incorporation of a high potential quinone reveals that electron transfer in Photosystem I becomes highly asymmetric at low temperature [PDF]

, 2012
Photosystem I (PS I) has two nearly identical branches of electron-transfer co-factors. Based on point mutation studies, there is general agreement that both branches are active at ambient temperature but that the majority of electron-transfer events ...

AAA+ protein unfoldases—the Moirai of the proteome

FEBS Letters, EarlyView.
AAA+ unfoldases are essential molecular motors that power protein degradation and disaggregation. This review integrates recent cryo‐electron microscopy (cryo‐EM) structures and single‐molecule biophysical data to reconcile competing models of substrate translocation.

Direct observation of electron transfer in solids through X-ray crystallography

Nature Communications
Nanoscale electron transfer (ET) in solids is fundamental to the design of multifunctional nanomaterials, yet its process is not fully understood. Herein, through X-ray crystallography, we directly observe solid-state ET via a crystal-to-crystal process.
