Rapid detection and quantification of ultralow‐concentration nanoparticles based on nanopore array blockage

Rami Yazbeck, Jiayi Xu, Yiding Zhong, Yixin Xu et autres

Abstract Rapid and accurate detection of ultralow‐concentration nanoparticles is crucial for applications ranging from medical diagnosis to water quality monitoring, yet remains challenging for current laser‐based and light‐scattering methods. While nanoparticle‐translocation‐based nanopore sensing offers single‐particle resolution, conventional single‐nanopore resistive pulse sensing approaches …

Nanoparticle Lubricant and Imaging Agent: Preventing and Assessing Cartilage Tissue Damage

Taylor B. Lawson, Anisha Joenathan, Christian D. DeMoya, Liangwei Zheng et autres

Introducing additives to industrial lubricants reduces friction and wear between articulating metal surfaces by mechanistically impeding interfacial adhesion, heat dissipation, and abrasion. With this inspiration, we report the synthesis and use of tantalum oxide (Ta 2 O 5 ) nanoparticles as a …

Enhancing Hydrogen Evolution Reaction through Coalescence-Induced Bubble Departure on Patterned Gold–Silicon Microstrip Surfaces

Chung‐Te Huang, Liangwei Zheng, Yiding Zhong, Jörg G. Werner et autres

Hydrogen bubble adhesion to the electrode presents a major obstacle for green hydrogen generation via the hydrogen evolution reaction (HER) as it would induce undesired overpotential and undermine the reaction efficiency by reducing reaction area, increasing transport resistance, and creating an undesired …
