Waste polyamide-derived CQDs show continuous photoluminescence tuning from 308 to 552 nm through sequential defect-state engineering, with optical transition energies decreasing from 4.32 to 2.50 eV. @Christian Ebere Enyoh from Saitama University Carbon quantum dots (CQDs) are fluorescent carbon nanomaterials with potential applications in sensing, optoelectronics, displays, anti-counterfeiting, and environmental technologies. Their optical properties can be adjusted by modif

The researchers used circularly polarized light at normal incidence and found that helicity-dependent photocurrents appeared perpendicular to the crystal’s polarization but vanished when measured parallel to it, supporting a bulk origin of CPGE. @Institute of Science Tokyo The circular photogalvanic effect (CPGE), a phenomenon that generates helicity-dependent photocurrents in noncentrosymmetric materials, can originate purely from a crystal's internal structure without contr

Summary of gold nanoparticle growth programming in liposome based on localization of biomineralization peptide The position of biomineralization peptides within liposomes can influence how gold nanoparticles grow, reports a research team from Institute of Science Tokyo. Peptides localized at the membrane interface promote branched structures, while those confined to the liposome interior favor spherical nanoparticles. The findings offer a new strategy for controlling nanoscal

The hierarchically structured membrane consists of three layers that enable the selective separation of ions using light and an electric field. A newly developed membrane makes it possible to selectively influence the permeability of ions using light and an electrical voltage. Lithium, magnesium, potassium and many other ions usually occur together in natural and technical solutions. Separating them from one another in a targeted manner is a challenge, for example, in the ext

This is the first time that three properties, being piezoelectric, photothermal and antioxidant, have been combined in a single organic structure measuring 500 nanometres.

These are the new nanoparticles designed and produced by a research group at the Italian Institute of Technology (IIT-Istituto I

The AtomDiT framework turns an atomic-resolution electron micrograph into an atomic-scale digital twin. It identifies dislocation types and positions, and simultaneously reconstructs stress and chemical fields, all from the same local atomic environment descriptors. Credit: ©Science China Press Dislocations are the primary carriers of plastic deformation in metallic materials. They directly determine how metals respond to mechanical loading, giving them the ability to deform,
