Mechanisms of void formation in Ge implanted SiO2 films

, 2003
The present paper reports on annealing of Ge implanted SiO2 films and emphasize the observation of voids and the mechanism behind their formation which is considered new.

Voids and masonry behind finishing mortars detected by infrared thermography and ultrasonic measurements

, 2020
Infrared thermography (IRT) and ultrasonic velocity (USV) measurements were combined in an experimental study to evaluate their effectiveness when detecting holes and type of masonry behind 15-mm thick finishing mortar.

Predicting the effect of voids on mechanical properties of woven composites [PDF]

, 2018
An accurate yet easy to use methodology for determining the effective mechanical properties of woven fabric reinforced composites is presented. The approach involves generating a representative unit cell geometry based on randomly selected 2D orthogonal ...

Impact of Formwork Materials on Concrete Surface Quality

Buildings
Given the functional and aesthetic quality expected from concrete surfaces, this study investigated the influence of different formwork materials on their surface density, porosity, voids, and elementary chemical composition by relying on X-ray ...

Dual native G‐quadruplex folding is associated with chromatin looping at the MYC locus

FEBS Open Bio, EarlyView.
BG4‐detectable G‐quadruplex (G4) in HaCaT and NHEK keratinocytes identified folded and unfolded G4s enriched at promoters/TSSs and active enhancers, whereas unfolded G4s also overlapped weak/poised enhancers. At MYC–PVT1, 3C‐qPCR detected enhancer–promoter looping only when G4s were simultaneously folded at both regulatory elements under native ...

Investigation of the hydraulic characteristics and homogeneity of the microstructure of the air voids in the sustainable rigid pavement

Open Engineering
The present research investigates how incorporating waste concrete block aggregates (WCBA) in place of natural coarse (5–12 mm) aggregates (NCA) affect the characteristics of concrete pavement. The topography of the voids, water absorption, porosity, and

Structural and biochemical insights into the thermostable esterase Ta0887 from Thermoplasma acidophilum

FEBS Open Bio, EarlyView.
In this study, a novel esterase from the thermoacidophilic archaeon Thermoplasma acidophilum was biochemically and structurally characterized. Our results demonstrate that Ta0887 is a highly thermostable esterase that preferentially hydrolyzes p‐nitrophenyl hexanoate and possesses an α‐helical cap domain that likely contributes to its substrate ...

Magneto-elastic SV-wave at the interface of pre-stressed surface with voids under rotation

Journal of the Mechanical Behavior of Materials, 2016
The aim of this paper is to study the behaviour of reflection of SV- wave at a free surface under the effects of magnetic field, initial stress, rotation and voids.

Evaluating GenAI‐produced feedback on undergraduate bioscience essays against good higher education feedback practice

FEBS Open Bio, EarlyView.
This pilot study investigates the potential of Generative AI to provide formative feedback to students. ChatGPT was prompted to provide feedback on Year 1 Bioscience essays, which were evaluated against established good feedback practices. GenAI‐authored feedback had useful elements, but was limited in scope. GenAI may have potential to provide instant,

Selective elimination of quiescent cancer cells by dequalinium chloride via ROS‐mediated ferroptosis

FEBS Open Bio, EarlyView.
Dequalinium chloride (DQ) selectively eliminates quiescent cancer cells (QCCs) by amplifying mitochondrial ROS. QCCs exhibit elevated basal ROS and limited redox‐buffering capacity, making them vulnerable to further ROS increases. DQ‐induced ROS exceeds the tolerance threshold, triggering lipid peroxidation and ferroptosis, whereas proliferating cells ...
