Electrical characterization of the soft breakdown failure mode in MgO layers [PDF]

, 2009
The soft breakdown (SBD) failure mode in 20 nm thick MgO dielectric layers grown on Si substrates was investigated. We show that during a constant voltage stress, charge trapping and progressive breakdown coexist, and that the degradation dynamics is ...

Ro 31‐8220 suppresses bladder cancer progression via enhancing autophagy in vitro and in vivo

FEBS Open Bio, EarlyView.
The pan‐protein kinase C inhibitor Ro‐31‐8220 demonstrates potent anti‐bladder cancer effects both in vitro and in vivo by suppressing migration/invasion, inducing apoptosis and crucially activating autophagy, where blocking autophagy with chloroquine reduces its cell‐killing efficacy, suggesting its promise as a novel therapeutic candidate requiring ...

Study on the influence of O2 on the breakdown voltage and self-recovery characteristics of c-C4F8/N2 mixture

AIP Advances, 2018
The c-C4F8 gas is considered to have great potential as a gaseous medium for use in gas-insulated equipment due to its good insulation properties and its relatively low greenhouse gas potential (Global warming potential, GWP) relative to SF6.

High Breakdown-Voltage (>2200 V) AlGaN-Channel HEMTs With Ohmic/Schottky Hybrid Drains

IEEE Journal of the Electron Devices Society, 2018
In this paper, a high breakdown voltage of more than 2200 V in high-electron-mobility transistors (HEMTs) with AlGaN channel and a novel ohmic/Schottky-hybrid drain contact is achieved, which is the record breakdown voltage ever achieved on AlGaN-channel

Polydatin ameliorates ovalbumin‐induced asthma in a rat model through NCOA4‐mediated ferroautophagy and ferroptosis pathway

FEBS Open Bio, EarlyView.
In this research, a rat model of asthma was created using OVA, and polydatin served as an intervention. By inhibiting ferroautophagy mediated by NCOA4 and averting ferroptosis, polydatin has been demonstrated to reduce asthma. This work presents new ideas for investigating the mechanism of polydatin's ability to alleviate asthma, in addition to ...

A novel design of a silicon PIN diode for increasing the breakdown voltage

IET Circuits, Devices and Systems, 2022
This paper presents a new structure consisting of a silicon PIN junction with high breakdown voltage and low dark current with two Guard rings. To achieve the optimal structure, the effect of the parameters on the breakdown voltage and the dark current ...

Electrical polarization of nuclear spins in a breakdown regime of quantum Hall effect

, 2006
We have developed a method for electrical polarization of nuclear spins in quantum Hall systems. In a breakdown regime of odd-integer quantum Hall effect (QHE), excitation of electrons to the upper Landau subband with opposite spin polarity dynamically ...

Rethinking plastic waste: innovations in enzymatic breakdown of oil‐based polyesters and bioplastics

FEBS Open Bio, EarlyView.
Plastic pollution remains a critical environmental challenge, and current mechanical and chemical recycling methods are insufficient to achieve a fully circular economy. This review highlights recent breakthroughs in the enzymatic depolymerization of both oil‐derived polyesters and bioplastics, including high‐throughput protein engineering, de novo ...

Tryptophan metabolite atlas uncovers organ, age, and sex‐specific variations

FEBS Open Bio, EarlyView.
Tryptophan metabolites were analyzed across twelve organs, the central nervous system, and serum in male and female mice at three life stages. We found tissue‐, sex‐, and age‐specific differences, including increased indole‐3‐pyruvate and kynurenine in aging males.
