Investigating and Improving Student Understanding of Conductors and Insulators

open access: yesEducation Sciences, 2023
Concepts involving conductors and insulators are challenging at all levels of instruction. Here, we summarized an investigation of the difficulties that introductory students have pertaining to the charging of conductors and insulators and how that ...

Tribo-Electrification and Associated Segregation of Pharmaceutical Bulk Powders

open access: yesKONA Powder and Particle Journal, 2014
Powder handling operations can give rise to the tribo-electrification of particles, causing a number of problems such as risk of fire and explosion, particle adhesion to the walls of processing equipment and ...

Anionic Lipids: A Pipeline Connecting Key Players of Plant Cell Division

open access: yesFrontiers in Plant Science, 2019
How cells position their division plane is a critical component of cell division. Indeed, it defines whether the two daughter cells divide symmetrically (with equal volumes) or not, and as such is critical for cell differentiation and lineage ...

The Electromechanical Behavior of a Micro-Ring Driven by Traveling Electrostatic Force

open access: yesSensors, 2012
There is no literature mentioning the electromechanical behavior of micro structures driven by traveling electrostatic forces. This article is thus the first to present the dynamics and stabilities of a micro-ring subjected to a traveling electrostatic ...

Single-Capacitor Electret Impact Microgenerator

open access: yesMicromachines, 2016
A new type of electrostatic microgenerator is presented that converts mechanical microvibrational energy into electric energy. The energy conversion mechanism is as follows. External microvibrations are transmitted to the device frame.

Interaction and Polarization Energy Relationships in σ-Hole and π-Hole Bonding

open access: yesCrystals, 2020
We demonstrate that a wide range of σ- and π-hole interaction energies can be related to (a) the electrostatic potentials and electric fields of the σ- and π-hole molecules at the approximate positions of the negative sites and (b ...

Particle-Induced Electrostatic Repulsion within an Electric Curtain Operating below the Paschen Limit

open access: yesMicromachines, 2022
The electric curtain is a platform developed to lift and transport charged particles in air. Its premise is the manipulation of charged particles; however, fewer investigations isolate dielectric forces that are observed at lower voltages (i.e., less ...

Single-Electrode Electrostatic Repulsion Phenomenon for Remote Actuation and Manipulation

open access: yesResearch
One of the fundamental principles of electrostatics is that an uncharged object will be attracted to a charged object through electrostatic induction as the two approaches one another.

Reciprocal control of viral infection and phosphoinositide dynamics

open access: yesFEBS Letters, EarlyView.
Phosphoinositides, although scarce, regulate key cellular processes, including membrane dynamics and signaling. Viruses exploit these lipids to support their entry, replication, assembly, and egress. The central role of phosphoinositides in infection highlights phosphoinositide metabolism as a promising antiviral target.
