Electrospun Carbon Nanofiber‐Based Multifunctional Electrocatalysts for Zinc‐Air Batteries and Overall Water Splitting: Fabrication, Progress, and Perspective

Rare Metals, EarlyView.
ABSTRACT The development of high‐performance and stable electrocatalysts for oxygen reduction reaction (ORR), oxygen evolution reaction (OER), and hydrogen evolution reaction (HER) plays a critical role in advancing clean energy technologies, including metal‐air batteries and hydrogen production through overall water splitting.

Chemically‐Linked Heterostructures of Palladium Nanosheets and 2H‐MoS2

Small, EarlyView.
The photoresponse of MoS2 devices is extended to the near‐infrared region (up to 1700 nm) through chemical connection to Pd nanosheets (PdNS). A maleimide is used for covalent connection to MoS2, and a phenyl bromide moiety for linkage to the PdNS. In the absence of the chemical linker, van der Waals heterostructures show poorer enhancement of the ...

Phase Hologram by Acoustic Metasurfaces

Small Structures, EarlyView.
This work has achieved a breakthrough in holographic communication, realizing phase holographic imaging. The proposed phase holographic concept overcomes the limitations of traditional amplitude holographic energy attenuation. The design of its amplitude compensation method further addresses the key challenge of phase holographic imaging clarity ...

Modulated electrochemical force microscopy: Investigation of sodium‐ion transport at hard carbon composite anodes

Journal of Microscopy, EarlyView.
Abstract For sodium (Na)‐ion batteries (SIBs), the next generation of sustainable batteries, hard carbon (HC) composite electrodes are the most used anodes. Here, we demonstrate the potential of modulated electrochemical force microscopy (mec‐AFM) to investigate electrochemical strain due to ion insertion at the electrolyte/electrode interface.

Refined Division of Sleep Stages in the Mouse Based on Distributed Deep Electrodes and Underlying Infra‐Slow Oscillation

Journal of Sleep Research, EarlyView.
ABSTRACT The mouse sleep is mostly recorded with only epidural electrodes and divided simply into NREM and REM stages. With the help of distributed intracerebral triplet electrodes, we searched for possible new electrophysiological signatures to characterise more specific sleep substages within the timeframe of seconds to tens of minutes.

Determining properties of human‐induced pluripotent stem cell‐derived cardiomyocytes using spatially resolved electromechanical metrics

The Journal of Physiology, EarlyView.
Abstract figure legend In this study, we use human‐induced pluripotent stem cell‐derived cardiomyocyte (hiPSC‐CM) experiments and computational modelling to identify the mechanism of action of drug compounds. In the hiPSC‐CM experiments, optical measurements of cell collections are recorded in the baseline case and after drug exposure.

Investigation of Dam Safety Making Use of Multichannel Analysis of Surface Wave (MASW) Seismic Method

, 2013
Multichannel Analysis of Surface Wave (MASW) seismic method is widely used in geotechnical engineering for the measurement of shear wave velocity and evaluation of material property. This method was recently conducted at a Dam site located in Zaria, within the basement complex of northern Nigeria.
