Research Progress on Flexible Oxide-Based Thin Film Transistors

open access: yesApplied Sciences, 2019
Oxide semiconductors have drawn much attention in recent years due to their outstanding electrical performance, such as relatively high carrier mobility, good uniformity, low process temperature, optical transparency, low cost and especially flexibility.

Application of multireflection grazing incidence method for stress measurements in polished Al–Mg alloy and CrN coating [PDF]

open access: yes, 2012
Multi-reflection grazing incidence geometry, referred to as MGIXD, characterized by a small and constant incidence angle, was applied to measure low surface stresses in very thin layers of Al–Mg alloy and CrN coating.

A tension-adhesion feedback loop in plant epidermis

open access: yeseLife, 2018
Mechanical forces have emerged as coordinating signals for most cell functions. Yet, because forces are invisible, mapping tensile stress patterns in tissues remains a major challenge in all kingdoms. Here we take advantage of the adhesion defects in the

Origin of slow stress relaxation in the cytoskeleton

open access: yes, 2019
Dynamically crosslinked semiflexible biopolymers such as the actin cytoskeleton govern the mechanical behavior of living cells. Semiflexible biopolymers nonlinearly stiffen in response to mechanical loads, whereas the crosslinker dynamics allow for ...

Mechanical Stress Effects on 4H-Silicon Carbide Power Diodes

open access: yesIEEE Open Journal of Power Electronics
This study discusses the effect of stress on 4H-silicon carbide (4H-SiC) power diodes using numerical simulations. Two power diodes were evaluated; namely, a 600 V PiN diode and 1.8 kV junction barrier Schottky (JBS) diode.

Deciphering caveolar functions by syndapin III KO-mediated impairment of caveolar invagination

open access: yeseLife, 2017
Several human diseases are associated with a lack of caveolae. Yet, the functions of caveolae and the molecular mechanisms critical for shaping them still are debated.

Monitoring weed mechanical and chemical damage stress based on chlorophyll fluorescence imaging

open access: yesFrontiers in Plant Science, 2023
Currently, mechanical and chemical damage is the main way to carry out weed control. The use of chlorophyll fluorescence (CF) technology to nondestructively monitor the stress physiological state of weeds is significant to reveal the damage mechanism of ...
