Enhancing Ligand Epitope Mapping in Biomolecular Recognition by Variable Temperature Saturation Transfer Difference NMR (VT‐STD NMR)

Magnetic Resonance in Chemistry, EarlyView.
The impact of temperature on the analysis of STD NMR ligand epitope mapping has been thoroughly investigated. For protein–ligand complexes under fast exchange kinetics, a negligible temperature effect is observed. For the intermediate exchange regime, VT‐STD NMR allows to obtain better discriminated epitope mappings, hence enabling the accurate ...

Structural and Rheological Properties of Chitosan‐Biochar Composites Prepared With Waste Biomass‐Derived Biochar

Polymer Engineering &Science, EarlyView.
Chitosan dispersions containing biochar derived from vine pruning residue showed increasing shear stress and improved thermal stability with loading. Flow behavior was described by the Bingham plastic model in all cases. These results support the valorization of agricultural waste in functional biopolymer formulations.

Synthesis and application of alginate@CuFe2O4 polymeric spheres in 17‐β‐estradiol adsorption processes in Amazonian rivers

Polymer International, EarlyView.
Magnetic alginate beads, functionalized with copper ferrite, effectively remove 17‐β‐estradiol from Amazonian water, exhibiting optimized 238.65 μg g−1 capacity, fast 40 min kinetics, easy recovery, and successful remediation. Abstract The presence of endocrine‐disrupting compounds, such as 17‐β‐estradiol, in aquatic ecosystems poses a significant ...

Influence of sulfonation degree and deposition technique on the electrical and morphological properties of sulfonated polystyrene thin films

Polymer International, EarlyView.
Sulfonated polystyrene films with different degrees of sulfonation were fabricated using Langmuir–Schaefer and drop‐casting techniques. Both the deposition method and sulfonation level strongly affect film morphology and electrical response, governing the performance of these materials as ammonia gas sensors.

Schisandrin C Targets PPARγ to Induce Ferroptosis in Colorectal Cancer Cells and Promote M1 Macrophage Polarization

Phytotherapy Research, EarlyView.
Schisandrin C: A Dual Anti‐Colorectal Cancer Strategy Targeting PPARγ. ABSTRACT Colorectal cancer (CRC) remains a leading cause of cancer mortality, necessitating novel therapeutic strategies. Schisandrin C (SinC), a bioactive lignan from Schisandra chinensis, exhibits diverse pharmacological activities, but its anti‐CRC mechanisms are poorly ...

Mixed TiO2–SiO2 thin coatings for selective adsorption and sunlight‐powered photodegradation of cationic pollutants

Responsive Materials, EarlyView.
Environmental pollution and water scarcity demand innovative purification methods. This study presents a sol‐gel approach to fabricate mixed silica–titania thin films joining photocatalytic activity with selective sorption capability. The films exhibit higher surface area, enhanced degradation of cationic and improved performance over bare titania ...

Solar‐Powered Water Depollution Through a Bioinspired Device Based on ZIF‐8 Loaded Macroporous Hydrogels Prepared via Ice‐Templating

Small, EarlyView.
ABSTRACT Water pollution poses a constant threat to the environment and is one of the central causes for global shortage of clean water. Metal–Organic Frameworks (MOFs) have emerged as highly efficient adsorbents; however, their application is limited by their common production as fine powders, which hinders recovery and reuse.

Photo‐Switched Catalytic Amyloids

Small, EarlyView.
Photo‐switched reversible hierarchical assembly of catalytic amyloid fibrils is accomplished by mixing an amphiphilic cross‐ß peptide with a merocyanine photo switch. The peptide monomers, comprising phenylalanine‐lysine repeats, do not self‐assemble in water because of the electrostatic repulsion.

Adsorption‐Programmed Transformation of a Two‐Dimensional Cu–Imidazolate Framework into Mn‐Integrated Catalytic Nanonetwork

Small, EarlyView.
A freeze‐dried copper‐based metal‐organic framework removes more than 95% of manganese from water. Capturing the metal reorganizes the framework, giving the used adsorbent a second life as a reusable catalyst that produces valuable ester products in yields up to 84%.
