Nonlinear electrical impedance spectroscopy of viruses using very high electric fields created by nanogap electrodes

Frontiers in Microbiology, 2015
Our living sphere is constantly exposed to a wide range of pathogenic viruses, which can be either known, or of novel origin. Currently, there is no methodology for continuously monitoring the environment for viruses in general, much less a methodology ...

A Breadth‐First Pruned‐Enriched Rosenbluth Method for Force–Extension Simulations of Confined Semiflexible Chains

Advanced Intelligent Discovery, EarlyView.
The behaviors of semiflexible polymers such as DNA and protein are often reshaped by coupled interactions. Monte Carlo simulations assist in studying these systems. This work recasts the traditional chain‐growth strategy into a new framework: a fixed number of chains grow synchronously, while less relevant chains to the target system are removed and ...

A Fixed‐Charge Interphase Synchronizes Ion Transport to Suppress Space‐Charge‐Driven Inefficiency Under Nanoliter Confinement

Angewandte Chemie International Edition, EarlyView.
Electrochemical energy storage breaks down under extreme miniaturization, where interfaces and space‐charge dominate device behavior. This work introduces a fixed‐charge selective interphase (FCSI) integrated into a twin‐tube micro‐Swiss‐roll architecture.

Grid Independence Study and a Finite Difference Collocation Approach for Magnetized CeO2‐Ti3C2/H2O Hybrid Nanofluid Flow Over an Inclined Spinning Disk With Newtonian Heating

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT This work examines magnetohydrodynamic (CeO2, Ti3C2/H2O) hybrid nanofluid (HNF) flow on an inclined revolving disk with effects of Newtonian heating. HNF is obtained by suspending the nanoparticles (NPs) of CeO2 and Ti3C2 in water (H2O). The flow is affected by mixed convection, Joule heating, nonlinear thermally radiative and dissipative ...

Engineering Mechanically Adaptive Nanonetworks for Long‐Life and High‐Capacity Silicon Anode Batteries

Carbon Energy, EarlyView.
ABSTRACT Silicon anodes, with a theoretical capacity of ~ $\unicode{x0007E}$3860 mAh g−1, offer more than ten times the lithium storage of graphite but suffer from large volume expansion during lithiation, leading to particle fracture, electrical disconnection, and unstable solid–electrolyte interphases (SEIs).

Sufficient Gas and Solvated Ion Transport Assisted Rapid NH3 Detection at Room Temperature Through Bionic Olfactory Fibres

Exploration, EarlyView.
Bionic olfactory fibres with nanoconfined ionic liquids were developed to mimic human olfactory cilia. Benefiting from sufficient gas transport pathways provided by inter‐fibre interconnected pores and rapid transport of solvated ions in the confined nano spacing, bionic olfactory fibres show excellent sensing performance to NH3 and demonstrate the ...

Synergistic Multi‐Strategy Engineering of Temperature‐Responsive Self‐Trapped Excitons in Tin‐Based Double Perovskite Nanocrystals Enables High‐Sensitivity Fluorescence Thermometry

Laser &Photonics Reviews, EarlyView.
Bi3+‐doped Cs2SnCl6 nanocrystals are engineered to deliver highly temperature‐responsive self‐trapped exciton emission, achieving record thermal sensitivity at elevated temperatures. A temperature‐induced dual‐STE excited state landscape enables reversible thermochromism, while a dual‐parameter calibration combining fluorescence lifetime and CIE‐y ...
