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.

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.

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.

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.
