Gold nanoparticles coated with the lectin Concanavalin A generated dose-dependent SERS signals from a model sugar and differential spectral profiles for three bacterial species, according to a new open-access study in Gold Bulletin.
A new mobile biochar production unit capable of turning forestry residues and invasive weeds into a useful soil product is being trialled in by the NSW Department of Primary Industries and Regional Development (DPIRD) in northern NSW, with researchers investigating…
Zinc oxide nanoparticles biosynthesized by a Penicillium citrinum endophyte from hibiscus leaves inhibited S. aureus lipase and hyaluronidase, reduced biofilm biomass by up to 68.7 percent and killed the bacterium in laboratory assays.
Strontium hexaferrite nanoparticles processed by annealing, milling and PEGylation killed a substantial fraction of murine cancer cells in vitro under a low-frequency alternating magnetic field. Strontium hexaferrite (SrFe12O19) nanoparticles, a chemically robust hard-magnetic material with high magnetic anisotropy, have been engineered…
Flexible and wearable electronics generate localized heat that must be spread quickly without compromising mechanical stability or electromagnetic performance. A new study reports a flexible multifunctional heat spreader built from a reduced graphene oxide aerogel-based composite structure that addresses all…
A new review in Discover Chemical Engineering examines how band-engineered heterostructure photocatalytic micromotors could improve autonomous water remediation while questioning whether lab performance gains hold up under realistic conditions. The review identifies several persistent obstacles that limit practical performance: rapid…
We've all heard the story: biochar cleans water by adsorbing pollutants -- trapping them like a sponge. Or, in fancier setups, it acts as a catalyst to help oxidants like hydrogen peroxide break down toxins. But Dr. Gao's team asked a…
Adjusting the nitrogen-to-boron ratio in sawdust-derived biochar boosted sulfamethoxazole degradation rates 2.35-fold by shifting the material from adsorption-driven to catalysis-driven pollutant removal. Subject of Research: Nitrogen and boron co-doped biochar catalysts for peroxymonosulfate activation and antibiotic degradation in water
SeNPs were synthesized via chemical reduction and physical pulsed laser ablation techniques. Stable, spherical nanoparticles with TEM diameters ranging from 20 to 150 nm (meanâ±âSD: 28.5â±â7.2 nm and 33.8â±â6.4 nm for the chemical and physical... Uncover the…
Macromolecular crowding can serve as a design tool for controlling the formation and organization of synthetic DNA droplets, a study from Science Tokyo reveals. Macromolecular crowding helps control synthetic DNA droplet formation Macromolecular crowding can serve as a design tool…
Materials built at the nanoscale: graphene and atom-thin sheets, nanoparticles and quantum dots, carbon nanotubes and nanotechnology research.
