Polyscias fruticosa (L.) Harms as a Functional Botanical Resource: A Quality-Gated Framework Linking Phytochemistry, Extraction Engineering, Bioactivity, and Application-Specific Development
23+ hour, 24+ min ago (424+ words) Polyscias fruticosa (L.) Harms is consumed as food and used traditionally in Southeast Asia, but reproducible ingredient development requires the alignment of raw material identity, chemical specification, processing, exposure, safety, and claims. This critical narrative review integrates species-specific studies with analytical,…...
Light-Responsive CNPPV-Conjugated Polymer Nanoherbicide for Controlled Release of Usnic Acid
23+ hour, 24+ min ago (242+ words) We report a visible-light-activated nanobioherbicide based on the conjugated polymer poly(2,5-di(hexyloxy)cyanoterephthalylidene) (CNPPV) for the controlled delivery of the natural bioherbicide usnic acid (UA). The nanostructures were fabricated by an adapted nanoprecipitation method, yielding spherical nanoparticles with a…...
From Laser Process to Function: Laser Texturing, Modification and Cleaning of Orthodontic Metallic Biomaterials—A Critical Appraisal of the Corrosion, Metal-Ion Release, Bacterial Adhesion and Friction Evidence for Stainless Steel, NiTi and β-Ti
23+ hour, 24+ min ago (438+ words) Laser surface engineering is increasingly proposed for orthodontic alloys, yet “laser texturing”, “laser modification” and “laser cleaning” denote physically distinct processes that act on the surface in opposite directions. This critical review asks whether reported laboratory benefits for corrosion, metal-ion…...
Physics-Guided Residual Learning for Full-Angular-Domain Scattering Prediction of Coding Metasurfaces
23+ hour, 24+ min ago (441+ words) Coding metasurfaces provide an effective approach for manipulating electromagnetic scattering through discrete coding states. However, obtaining angular-domain scattering responses for a large number of coding configurations remains computationally expensive with full-wave electromagnetic simulations. To address this issue, this work proposes…...
Nobel Prize for “Asymmetric Synthesis”
7+ hour, 42+ min ago (1686+ words) Every year, the first week in October, I eagerly await the announcement of the Nobel Prize in Chemistry. If Louis Pasteur were alive today, he would be thrilled with the 2026 honour being bestowed on French chemist Henri Kagan and Japanese…...
Potato peel extract as an ecologically conscious inhibitor for corrosion of A283 carbon steel in hydrochloric acid: experimental and theoretical perspectives
23+ hour, 24+ min ago (1383+ words) 1H NMR and 13C NMR both are acquired by Mercury, temperature of 30 °C, 300 MHz for 1H NMR and 75.46 MHz for 13C NMR, CD3OD as a solvent. Approximately 5–10 mg of the extract was dissolved in 0.6 mL of deuterated methanol (CD₃OD). The mixture was completely dissolved and then…...
Sewage ash heated with chlorine gas and carbon near 1,830 degrees Fahrenheit released 75 percent of its phosphorus as a gas, the nutrient that incineration normally locks into a form plain heat cannot release
1+ hour, 36+ min ago (620+ words) Inside a Japanese treatment plant, truckloads of sludge get burned down to ash. The leftover powder looks like cold gray dust. For decades, much of it went straight to a landfill. Locked inside is a nutrient every farm on Earth…...
Left-handed or right-handed? For molecules, it matters
3+ hour, 37+ min ago (489+ words) An illustration of the two mirror-image forms of alanine, an amino acid used to build proteins. Nobel-winning research on chiral molecules could improve medicines and help explain why life favors certain molecular forms. Graphic courtesy ASU School of Molecular Sciences…...
Testing eases Rotorua lake and forest ‘forever chemical’ fears
1+ hour, 52+ min ago (616+ words) The Rotorua Lakes Council is celebrating two environmental wins. It says testing has found no evidence of “forever chemicals” contaminating aquatic life in Lake Rotorua, nor significant ecological damage linked to more than three decades of treated wastewater irrigation in…...
Int'l journal lauds 1993 paper by researchers at Japan's Ehime Univ. as 'milestone'
3+ hour, 24+ min ago (487+ words) October 10, 2026 (Mainichi Japan) MATSUYAMA -- A 1993 scientific paper by researchers at Ehime University in western Japan on the global spread of persistent organic pollutants (POPs) has been selected by an international journal as one of 32 "milestone articles" that have contributed to…...
