Receptor‐Free Identification of Toxic Gases Enabled by Hygroscopic Aqueous Salt Films

Advanced Functional Materials, EarlyView.
Water as a gas sensor coating sounds impossible—until it stops evaporating. Here, hygroscopic salt solutions (LiCl, LiBr, H3PO4) form non‐drying aqueous films on CNT chemiresistors under ambient air. Gases partition into these liquid layers, sometimes transforming into water, and generate salt‐specific resistance fingerprints across a four‐channel ...

Spatially Modulated Morphotropic Phase Boundaries in a Compressively Strained Multiferroic Thin Film

Advanced Functional Materials, EarlyView.
ABSTRACT The coexisting rhombohedral‐like (R′, MA) and tetragonal‐like (T′, MC) monoclinic phases in compressively strained bismuth ferrite thin films exhibit exceptional piezoelectric and magnetic properties. While previous studies have largely focused on probing the morphotropic phase boundaries (MPBs) comprising ordered R′/T′ twins, their self ...

The mitochondrial voltage-dependent anion channel 1 in tumor cells

Biochimica et Biophysica Acta (BBA) - Biomembranes, 2015
VDAC1 is found at the crossroads of metabolic and survival pathways. VDAC1 controls metabolic cross-talk between mitochondria and the rest of the cell by allowing the influx and efflux of metabolites, ions, nucleotides, Ca2+ and more. The location of VDAC1 at the outer mitochondrial membrane also enables its interaction with proteins that mediate and ...

Deterministic Model of the Voltage Dependent Anion Channel (VDAC) Kinetics

, 2020
The voltage-dependent anion channel (VDAC) is a voltage gated channel residing on the outer mitochondrial membrane (OMM) that facilitates the flow of metabolites between the cytosol and mitochondria.

Cell demise inhibited: Unexpected liaisons between mitochondria and IκΒα

Molecular & Cellular Oncology, 2021
IκΒα (the protein product of NFKBIA gene) has widely been considered a pro- apoptotic factor due to its ability to inhibit the anti-apoptotic transcription factor NFκB.

Electrode and Microstructure Dependence of Oxygen Diffusion in Ferroelectric Hafnium Zirconium Oxide Thin Films

Advanced Functional Materials, EarlyView.
Significant nanoscale oxygen diffusion coefficient variations are measured in ferroelectric hafnium zirconium oxide films with grain boundaries and electrode interfaces exhibiting values 104 times larger than the grain cores. Overall coefficients are 10X larger for films prepared with metal nitride electrodes compared to refractory metals. New insights

LRRC8/VRAC anion channels enhance β-cell glucose sensing and insulin secretion

Nature Communications, 2018
Insulin secretion by β-cells is stimulated by glucose and is dependent on the induction of β-cell membrane depolarization, mainly driven by the closure of KATP channels, which in turn promotes voltage-gated Ca2+ channel opening.
