Expression, Purification, and Microscopy‐Based Assays for Engineered Recombinant Tyrosinated, Detyrosinated, and Δ2 Human Tubulin

Cytoskeleton, EarlyView.
ABSTRACT Microtubules are noncovalent polymers assembled from α/β tubulin dimers. Their structure, dynamics and interaction with effectors are regulated through the expression of diverse tubulin isotypes and chemically diverse posttranslational modifications, also known as the “tubulin code.” Understanding the biophysical correlates between tubulin ...

Co‐Catalyst/Semiconductor Interface Coupling Design for Efficient Solar‐Driven Photocatalysis

EcoEnergy, EarlyView.
Interfacial coupling strength is proposed as a unifying descriptor governing charge‐transfer behavior in co‐catalyst/semiconductor photocatalytic systems. This review establishes a coupling‐strength‐guided framework that correlates interface engineering strategies with charge transport pathways, electronic structure regulation, and photocatalytic ...

Polyelectrolyte Layer as a Work Function Modifier for Transparent Electrodes Enabling Efficient Perovskite Solar Cells With Superior Low‐Light Performance

EcoEnergy, EarlyView.
Polyelectrolytes represent a low‐cost and effective platform for tailoring charge extraction interfaces in inverted perovskite solar cells (PSCs). In this work, we introduce a protonated polyethyleneimine (PEI) layer (pH = 2) between the ITO electrode and the PTAA hole transport layer to increase the apparent work function of ITO by 0.066 eV and reduce

Capillary Electrophoresis Methods for the Characterization of Synthetic Nanoparticles

ELECTROPHORESIS, EarlyView.
Capillary electrophoresis (CE) can be applied to evaluate nanoparticle (NP) size, charge, and surface characteristics. Hyphenating CE with ICP‐MS and AF4 can provide comprehensive, multidimensional NP characterization. ABSTRACT Nanoparticles (NPs) exhibit properties distinct from bulk materials of identical chemical composition, with their behavior and

Adeno‐associated virus‐mediated restoration of NaV1.1 in targeted brain regions ameliorates epilepsy in symptomatic Dravet syndrome mice

Epilepsia, EarlyView.
Abstract Objective Dravet syndrome (DS) is a developmental and epileptic encephalopathy primarily caused by haploinsufficiency of the SCN1A gene, which encodes the alpha subunit of NaV1.1 voltage‐gated sodium channel. The disease manifests with febrile and spontaneous seizures, developmental delay, cognitive impairment, and increased risk of sudden ...
