Crack propagation speed in ceramic during quenching

open access: yes, 2018
The effects of water quenching temperature and specimen size on the propagation speed of thermal shock crack are investigated in real time by water quenching of translucent ceramic and high-speed imaging.

The Dark Side: Photosensitizer Prodrugs

open access: yesPharmaceuticals, 2019
Photodynamic therapy (PDT) and photodiagnosis (PD) are essential approaches in the field of biophotonics. Ideally, both modalities require the selective sensitization of the targeted disease in order to avoid undesired phenomena such as the destruction ...

Using fluorescence fluctuation spectroscopy to quantify molecular dynamics within cells

open access: yesFEBS Open Bio, EarlyView.
Microscopy techniques like fluorescence correlation spectroscopy (FCS) and number and brightness analysis (N&B) allow to quantify concentrations, diffusion rates, and oligomerization of fluorescently labeled molecules in the living cell. In this protocol the principles of how to set up these types of experiments are described including calibration ...

Sonoluminescence quenching by organic acids in aqueous solution: pH and frequency effects [PDF]

open access: yes, 2002
The quenching of sonoluminescence from aqueous solutions by acrylic and methacrylic acids is dependent on whether the acid is ionised in solution, as controlled by the pH, but also by the frequency of ultrasound ...

Numerical quenching for a semilinear parabolic equation

open access: yesMathematical Modelling and Analysis, 2008
This paper concerns the study of the numerical approximation for the nonlinear parabolic boundary value problem with the source term leading to the quenching in finite time.

In vitro generation of regulatory T cells: A challenging tool for studying immune aging in humans

open access: yesFEBS Open Bio, EarlyView.
In vitro induction of human regulatory T cells using standard protocols generates suppressive, Foxp3‐expressing CD4+ T cells independently of TGF‐β supplementation and donor age. Regulatory T (Treg) cells play a key role in immune tolerance and homeostasis.

2,5-PRODAN Derivatives as Highly Sensitive Sensors of Low Solvent Acidity

open access: yesMolecules, 2014
Two 5-acyl-2-dimethylaminonaphthalene derivatives, one with a propionyl group and the other with a fused cyclohexanone ring, are investigated as sensors of H-bond-donating ability in protic solvents of low solvent acidity.

Characterization of the key membrane protein cytochrome Cyc2 from Ghiorsea bivora

open access: yesFEBS Open Bio, EarlyView.
This study reports the first detailed biochemical analysis of Cyc2TAG1_1, a cytochrome protein involved in microbial iron oxidation. We produced and purified this enzyme in E. coli, then measured its iron‐oxidizing efficiency, and characterized its electrical and structural properties.

Quenching Theory and Technology

open access: yes, 2010
Quenching is one of the most fundamentally complex processes in the heat treatment of metals, and it is something on which mechanical properties and distortion of engineering components depend.

Site, trigger, quenching mechanism and recovery of non-photochemical quenching in cyanobacteria: recent updates [PDF]

open access: yes, 2018
Cyanobacteria exhibit a novel form of non-photochemical quenching (NPQ) at the level of the phycobilisome. NPQ is a process that protects photosystem II (PSII) from possible highlight-induced photo-damage.
