Synergistic Mn/N/F Tri-Doped TiO2 Nanoparticles: Bandgap Narrowing and Defect Passivation for Solar-Driven Pollutant Degradation [PDF]

Iranian Journal of Chemistry & Chemical Engineering
The persistent challenge of organic pollutant remediation demands efficient solar-driven photocatalysts. Titanium dioxide (TiO2), though widely used, suffers from a wide bandgap (~3.2 eV), limiting activity to UV light and rapid charge recombination ...

Artificial molecular machines and motors—Design and control of nanoscale motion

FEBS Letters, EarlyView.
Molecules are constantly moving because of thermal fluctuations, but random motion alone cannot be exploited to perform directional tasks. Artificial molecular machines use chemical, electrical, or light energy to bias this motion. Molecular shuttles, rotary motors, and supramolecular pumps illustrate how nanoscale movement can be controlled and ...

Formulation and characterization of BBR loaded niosomes using saponin as a nonionic biosurfactant investigating synergistic effects to enhance antibacterial activity

Scientific Reports
This study aimed to enhance the antibacterial efficacy of BBR, a natural alkaloid with limited bioavailability and solubility, by encapsulating it in niosomes using saponin as a biosurfactant.

The heterodimeric amino acid transporters (HAT) of the SLC7/SLC3 family: A structure−function relationships and relevance to human pathology

FEBS Letters, EarlyView.
Heterodimeric amino acid transporters consist of SLC7 and SLC3 family proteins arranged in a conserved structural organization. They regulate nutrient transport across cell membranes, supporting essential cellular functions. These transporters also contribute to xenobiotic/drug uptake and distribution.

Enzymatic protein hydrolysates of a residue from grape by-products industry for winemaking application: influence of the starting material and hydrolysis time

Cogent Food & Agriculture
Large quantities of defatted grape seed meal (DGSM) are discarded annually in the grape pomace industry. This residue could be exploited as a new source of non-animal protein to improve the chemical and color stabilization of red wines from warm regions.

Smaller is better: nanobodies meet NMR

FEBS Letters, EarlyView.
Nanobodies are single‐domain antigen‐binding fragments derived from camelid heavy chain antibodies. Their small size, high stability, and exceptional specificity make nanobodies uniquely useful probes for NMR studies of protein dynamics, transient conformational states, and protein–protein interactions.

The Coloring of Graphs [PDF]

Proceedings of the National Academy of Sciences, 1931
In another paper, L,3 the author has given a proof of a formula for M(λ), the number of ways of coloring a graph in λ colors, due to Birkhoff. The numbers m ij , in terms of which M(λ) is expressed, are here studied in detail; a method of calculating them is given.

Distribution of colors in Gallai colorings

European Journal of Combinatorics, 2020
A Gallai coloring is an edge coloring that avoids triangles colored with three different colors. Given integers $e_1\ge e_2 \ge \dots \ge e_k$ with $\sum_{i=1}^ke_i={n \choose 2}$ for some $n$, does there exist a Gallai $k$-coloring of $K_n$ with $e_i$ edges in color $i$?

Invisible but not inaccessible—Revealing transient oligomers formed by intrinsically disordered proteins with solution NMR and complementary methods

FEBS Letters, EarlyView.
Transient oligomers formed by intrinsically disordered proteins may be ‘invisible’ to direct detection yet remain accessible to solution NMR through equilibrium‐exchange measurements and pressure‐jump experiments. Complementary methods report on mass, stoichiometry, selected distance distributions, morphology, and internal packing.
