Conserved binding mode but diverse interfaces of MreC‐PBP2 interactions

FEBS Letters, EarlyView.
The crystal structure of abMreC reveals a conserved two β‐barrel architecture and provides structural insights into its role within the bacterial elongasome. The abMreC–abPBP2 complex model identifies the molecular basis of MreC‐mediated PBP2 recognition, contributing to the regulation of peptidoglycan synthesis.

Effects of Trapping Characteristics on Space Charge and Electric Field Distributions in HVDC Cable under Electrothermal Stress

Energies, 2021
Space charge behavior has a strong impact on the long-term operation reliability of high voltage–direct current (HVDC) cables. This study intended to reveal the effect of trap density and depth on the space charge and electric field evolution behavior in

Accumulated space-charge in stationary- and steady-state

Journal de Physique III, 1992
Nous présentons une nouvelle approche de la description de la charge d'espace accumulée dans l'état stationnaire et statique dans une homostructure multicouches (n+-n-n+). L'évolution statique des populations accumulées de fractions de porteurs libres est considérée dans le cadre de l'approximation quasi-équilibre comme une fonction de la polarisation ...

Identification of the plant mitochondrial OrfX protein: A mass spectrometry approach

FEBS Letters, EarlyView.
The mitochondrial genome of plants contains an open reading frame, orfx, which encodes a rare protein that has so far escaped mass spectrometric detection. The protein resembles the c‐subunit of bacterial twin‐arginine‐motif‐dependent protein translocases (TatC).

Study on space charge accumulation characteristics of silicone elastomer under DC voltage

High Voltage
The electric field distortion caused by the accumulation of space charge in the insulating dielectric is easy to lead to accelerated ageing and even breakdown. In this paper, the space charge characteristics and the interfacial electric field change with

Effect of Pre-Qualification Test on Space Charge Accumulation Phenomenon

2023 IEEE Conference on Electrical Insulation and Dielectric Phenomena (CEIDP), 2023
This paper is focused on the measurement of space charge in flat specimens deriving from a cable subjected to the Pre-Qualification (PQ) test. In particular, before starting the PQ test and after finishing them, the flat specimens have been taken from the cable.

Discerning protein pools by selective staining with self‐labeling tags

FEBS Letters, EarlyView.
Cell surface proteins have an intra‐ and extracellular pool. Combining genetic fusion to self‐labeling tags that can be addressed with small molecule fluorophores allows separating these pools. We highlight recent developments and techniques for state‐of‐the‐art interrogation of cell surface proteins in the complex tissue setting.

Boosting output performance of sliding mode triboelectric nanogenerator by charge space-accumulation effect

Nature Communications, 2020
Improving the output performance of sliding mode triboelectric nanogenerators is a great challenge. Herein, a space charge accumulation effect, based on alternating shielding and blank-tribo areas, is demonstrated and effectively promotes charge density ...

Numerical simulation of charging up, accumulation of space charge and formation of discharges

Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment
Aging and stability of gaseous ionization detectors are intricately related to charging up, accumulation of space charge and formation of discharges. All these phenomena, in their turn, depend on the dynamics of charged particles within the device. Because of the large number of particles involved and their complex interactions, the dynamic processes ...
