Karl Popper and the Mechanisms of Hydrogen Embrittlement

Advanced Engineering Materials, EarlyView.
Representation of the beginning of loss of ductility rather than embrittlement. Small concentrations of hydrogen in a diffusible form within iron are well‐established to harm the mechanical integrity of steels. There are theories that attempt to explain the pernicious role of hydrogen.

A method to measure molecular hybridization.

PLoS ONE
Fluorescence-based oligonucleotide probes have a great importance in research of molecular interactions. Molecular beacons (MBs) are special case of fluorescent probes that form a stem-loop shape, bringing together a fluorophore and quencher, thus ...

Engineered dual-fluorescence functional nucleic acid-based CRISPR/Cas12a biosensor for label-free ratiometric detection of site-specific DNA methylation

Synthetic and Systems Biotechnology
The CRISPR/Cas12a system holds significant promise for biomedical applications. Nevertheless, the commonly used reporter, fluorophore–quencher-labeled substrates, is hindered by labor-intensive synthesis procedures and high costs, while also relying on a

Microstructure Evolution of a VMnFeCoNi High‐Entropy Alloy After Synthesis, Swaging, and Annealing

Advanced Engineering Materials, EarlyView.
The synthesis and processing (rotary swaging and annealing) of the novel VMnFeCoNi alloy is investigated, alongside the estimation of the grain size effect on hardness. Analysis of a wide grain size range of recrystallized microstructures (12–210 µm) reveals a low annealing twin density.

A simple and label-free proximity-catalytic hairpin reaction-based method for sensitive and miRNA analysis

Journal of Analytical Science and Technology
Aberrant expression of microRNAs (miRNAs) has been shown to be linked to several crucial biological processes, including as carcinogenesis, metastasis, and progression.

Influence of Test Temperature and Test Frequency on Fatigue Life of Aluminum Alloy EN AW‐2618A

Advanced Engineering Materials, EarlyView.
The influence of test temperature and test frequency on the fatigue life of EN AW‐2618A is investigated. High‐cycle fatigue tests are performed at different test temperatures and frequencies on the 1000 h/230°C overaged state. Both test parameters reduce fatigue life due to time‐dependent damage mechanisms.

"Lycopene: A Promising Antioxidant"

Journal of Indian Academy of Oral Medicine and Radiology, 2007
Lycopene is a red colored fat soluble carotenoid, which gives tomatoes and several other fruits their deep red colour. It has shown potential role in prevention and cure of various systemic and oral diseases including malignancies due to its antioxidant ...

The Carnosine–HNE Michael Adduct as a Redox-Active Species Associated with Nrf2-Dependent Antioxidant and Anti-Inflammatory Responses

Antioxidants
Carnosine (CAR), an endogenous histidine-containing dipeptide, exhibits antioxidant and anti-inflammatory activity in various experimental models; however, its molecular mechanism of action remains poorly understood. Here, we demonstrate that the Michael

Recycling of NiTi Shape Memory Alloys: Fundamental and Technological Aspects of a Vacuum Induction Melting Processing Route

Advanced Engineering Materials, EarlyView.
The present study investigates recycling of NiTi shape memory alloys via vacuum induction melting. An ingot was synthesized from elemental Ni and Ti and subjected to three subsequent remelting cycles. Remelting increases process durations and impurity levels and adversely affects microstructures and functional properties.

PRICE: direct and robust detection of microRNAs at single-nucleotide resolution

Nature Communications
Accurate single-nucleotide discrimination of miRNA is clinically vital because small sequence variations can have significant phenotypic and clinical consequences, yet existing techniques can only detect single nucleotide variations (SNVs) at specific ...
