Gold nanoparticles distinguish two forms of tryptophan in lab
The two tryptophan forms produced different colors and particle arrangements, while absorbance at one wavelength tracked the share of d-tryptophan in test mixtures.

Mouse Study Finds No Detected Toxicity After Local Silver Nanoparticle Dosing
Mice given the nanoparticle formulation Nowarta110 through the skin, oral mucosa or vagina once daily for 12 weeks showed no consistent treatment-related harm across clinical, laboratory, organ and tissue checks.

Zingiberene formulation tied to higher mineral markers in rats
A rat study found higher serum calcium, phosphate and alkaline phosphatase in fracture groups receiving free zingiberene or a zingiberene-selenium formulation than in fracture controls. The formulation's alkaline phosphatase reading was higher than free zingiberene's, but magnesium did not differ significantly between treatments.

Hydrogel carrying glycopeptide linked to faster wound healing in mice
A hydrogel carrying Lycium barbarum glycopeptide released more cargo under acidic lab conditions and was associated with faster wound closure in mice, but the study did not establish long-term safety or performance in other wound models.

X-ray scans show stronger iron oxide nanoparticle alignment in fields
Ferucarbotran samples produced increasingly anisotropic SAXS patterns as the static magnetic field rose, giving researchers a way to compare three measures of orientational order.

Review maps how hybrid light-matter systems move energy and charge
A literature-based Feature Article traces how polaritonic systems exchange energy, carry excitations and show reported changes in charge mobility, while highlighting gaps in the models used to describe them.

Cyanobacteria-made catalyst breaks down more crystal violet
A catalyst made with cyanobacterial extract achieved higher reported crystal violet degradation and total organic carbon removal than chemically synthesized NiO/CoO, though the tests used prepared dye solutions rather than real wastewater.

Study reports fast reactions with walnut-shell biochar in water
Amine-functionalized biochar made from walnut shells produced high reported yields for two reaction types in water at room temperature, but the study was small and descriptive.

Leaf-made zinc oxide nanoparticles show strong corrosion inhibition
The study compared Bauhinia purpurea leaf-extract-mediated zinc oxide nanoparticles made by co-precipitation and sol-gel synthesis in carbon-steel corrosion tests, with lower dissolved iron reported at 100 ppm than in the blank.

Alkali-intercalated WTe2 shows a new structure and narrow gaps
Intercalated WTe2 compounds containing potassium, rubidium or cesium showed a lower-symmetry crystal arrangement and progressively wider spacing between layers. Optical analysis and DFT calculations indicated narrow gaps, while temperature-dependent electrical measurements reported semiconducting behavior for Rb0.5WTe2 crystals.

Preprint links native defects to α-MnO₂’s electronic and optical behavior
A computational preprint models native interstitial, vacancy and antisite defects in ground-state C2-type antiferromagnetic α-MnO₂. It reports the oxygen vacancy as the most stable neutral defect, strong donor–acceptor compensation and defect-related sub-gap optical features, while stressing that equilibrium carrier type and real-world defect populations remain unestablished.
