Dynamic Characteristics of Vibrating Flip‐Flow Screens Considering Material Impact Force

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT Vibrating flip‐flow screens are widely used in the field of screening; its actual operation is affected by the impact force of materials, but existing research usually ignores this effect. Based on this background, considering the influence of material impact force and moment on vibrating flip‐flow screens, this paper develops a dynamic model ...

High‐Performance Oxidation and Nanomolar Detection of Phenylhydrazine Using a 6‐Hydroxyflavone‐Based Molecular Electrocatalyst Functionalized Multiwalled Carbon Nanotube in Batch Injection Analysis

ChemistryOpen, EarlyView.
This study presents a novel, rapid method for in situ functionalization of carbon electrodes using redox‐active form of the 6‐hydroxyflavone. The resulting multiwalled carbon nanotubes with redox‐active HFLA (MWCNT@HFLA‐Redox) electrode enables sensitive, selective detection of toxic phenylhydrazine, with excellent performance (limit of detection: 7 nM)
