The paper explores the creation and characterization of vesicles through biocatalytic Polymerization‐Induced Self‐Assembly (bioPISA), focusing on achieving size uniformity using centrifugation techniques. It examines the effects of stirring speed on vesicle morphology and analyses the internal polymer‐rich structure using fluorescence correlation ...

Grain Surface Models and Data for Astrochemistry [PDF]
The cross-disciplinary field of astrochemistry exists to understand the formation, destruction, and survival of molecules in astrophysical environments. Molecules in space are synthesized via a large variety of gas-phase reactions, and reactions on dust ...

Oxidative stress and protection against it in bacteria
Microorganisms are exposed to reactive oxygen species (ROS) that are formed in various ways, in particular, as a result of respiration or other intracellular processes, during metal-catalyzed Fenton reactions, as a result of the action of UV- and X ...

On the Hydrogen Recombination Time in Type II Supernova Atmospheres [PDF]
NLTE radiative transfer calculations of differentially expanding supernovae atmospheres are computationally intensive and are almost universally performed in time-independent snapshot mode. The validity of the steady-state approximation in the rate equations has recently been questioned.

The study presents a general cyanine‐based platform CySN for designing robust dual‐channel near‐infrared fluorescent (NIRF) and photoacoustic (PA) probes with high ratiometric signals change. CySN enables the construction of highly sensitive and selective dual‐channel NIRF/PA probes for both small molecule and enzyme biomarkers (H2O2, esterase ...

Bromination of hydrocarbons with CBr4, initiated by light-emitting diode irradiation
The bromination of hydrocarbons with CBr4 as a bromine source, induced by light-emitting diode (LED) irradiation, has been developed. Monobromides were synthesized with high efficiency without the need for any additives, catalysts, heating, or inert ...

First-principles study on various point defects formed by hydrogen and helium atoms in tungsten [PDF]
The different point defects formed by two hydrogen atoms or two helium atoms in tungsten were investigated through first-principles calculation. The energetically favorable site for a hydrogen atom is tetrahedral interstitial site while substitutional site is the most preferred site for a helium atom.

Dynamic linkages are highly attractive in preparing single crystals of covalent organic polymers (COPs). Here, single crystals of two COPs CityU‐15 and CityU‐16 based on reversible B─N bonds are constructed using tetra(4‐pyridyl)tetrathiafulvalene and tetra(4‐pyridyl)porphine as monomers.

In this study, a close correlation among the resting period, the cyclability of the zinc anode, and the evolution of byproduct zinc hydroxide sulfate (ZHS) is identified. Furthermore, it is shown that proper control of the interfacial ZHS can significantly enhance the cycle performance of the zinc anode by effectively inhibiting corrosion and promoting

Investigations of the structures and reactions of neutral free radicals in solution [PDF]
Before this work, no direct evidence for cyclisation of the 2-(isocyanatocarbonyl)ethyl radical to give the succinimidyl radical existed, because the latter radical had never been generated from acyclic reagents.
