This study introduces a paper‐based biodegradable, humidity‐insensitive e‐nose for real‐time breath analysis, addressing challenges in existing technologies such as humidity interference, high costs, and environmental impact. Featuring hydrophobic polymer coatings, these sensors reliably detect VOCs even in high‐moisture environments.

GPx4 is bound to peroxidized membranes by a hydrophobic anchor [PDF]
Ferroptosis is a form of cell death discovered in recent years, induced by excessive peroxidation of phospholipids. Glutathione peroxidase 4 (GPx4) is an intracellular enzyme that can repair the peroxidized phospholipids on membranes, thus regulating ferroptosis.

H2O2‐Generating Advanced Nanomaterials for Cancer Treatment
H2O2‐generating nanoplatforms can exploit tumor redox imbalance for O2 and toxic reactive oxygen species generation, leading to hypoxia reversal, and apoptosis of cancer cells, respectively. This review highlights the mechanisms of these nanoplatforms, including exogenous H₂O₂ delivery, endogenous amplification, and metal peroxides, which leads to ...

Photoinduced optical rotation in a racemic mixture of hydrogen peroxide molecules [PDF]
A problem of inducing a required sign of chirality in a racemic mixture of enantiomers of a chiral molecule is analyzed. As an example, a racemic mixture (vapor) of left- and right-handed enantiomers of hydrogen peroxide (H2O2) molecule is considered. It is shown that biharmonic Raman excitation of the splitted due to the left-right conversion internal

Ozone‐based gas‐phase metal‐assisted chemical etching enables unprecedented room‐temperature fabrication of high‐quality silicon nanowires. The superior oxidation potential of O3 drives rapid vertical etching (1 µm min−1) while maintaining exceptional structural integrity. The pristine nanowire surfaces enable high‐performance core‐shell photodetectors

On the crystal structure of lithium peroxide, Li2O2 [PDF]
The two published lithium peroxide structures, both ascribed to the hexagonal P -6 space group, were subjected to reinterpretation and another more symmetric structure, now belonging to the P 63/m m c space group, was found. Detailed density-functional quantum mechanical calculations and crystal structure optimisations were carried out on both ...

Rotating Liquid Marble Microreactors for Enhanced Enzymatic Reactions
Dynamic magnetic liquid marbles (LMs), stabilized by hydrophobic magnetic proteinaceous colloidosomes, function as effective microreactors for enzymatic processes. Precise magnetic manipulation allows for the rotation of these LMs, enhancing the efficiency of the enzymatic cascade reaction both at the air/water interface and within biphasic enzyme ...

Hydrogen peroxide generated by an atmospheric He-O2-H2O flowing post-discharge: production mechanisms and absolute quantification [PDF]
An atmospheric plasma torch has been supplied with a gaseous mixture of helium, water vapour and/or oxygen to study the production of reactive species within its flowing post-discharge, in particular hydrogen peroxide. The mechanisms responsible for the production of H2O2 have been investigated by correlating measurements of mass spectrometry and ...
