Short-lived radioactive isotopes, or radioisotopes, can image tumors or inflict high levels of cellular damage to them. As a result, these radioisotopes can be effectively used in cancer treatments.
From smartphones to data centers, modern electronics rely on billions of tiny switches that consume electricity every time they turn on or off.
Nanoglasses use nanoscale glass grains and distinct glass-glass interfaces to introduce controllable structural, chemical, and thermodynamic heterogeneity into amorphous materials. The perspective highlights columnar thin-film nanoglasses as a promising platform for tuning mechanical properties, atomic transport, magnetism, optics, and catalysis through interface engineering.
Researchers developed room-temperature polysaccharide coatings for titanium dioxide that suppress photocatalytic ROS generation while improving UV protection and the stability of sunscreen emulsions. Glucan-coated particles delivered approximately twice the in vitro SPF and UVAPF of commercial silica-coated TiO2, while coating thickness helped tune the balance between UVA and UVB protection.
Researchers compared TiO2, pomegranate peel-derived carbon dots, TiO2/CDs, and Cu-CDs/TiO2 for UV-driven CO2 reduction, finding that catalyst composition strongly shaped product selectivity. Carbon dots favored oxygenated products, TiO2/CDs strongly favored CO formation, and copper modification promoted hydrogenation pathways toward more reduced products such as alkanes.
Modern drilling fluids combine nanoparticles, responsive polymers, and digital monitoring to improve wellbore stability, limit formation damage, and preserve reservoir permeability. These systems may also strengthen subsequent enhanced oil recovery by supporting wettability alteration, mobility control, and more effective fluid displacement.
Researchers showed that surface chemistry directs two types of diblock copolymer nanoparticles into separate core and near-surface regions of growing calcite crystals. Calcium-dependent colloidal stability and polymer–mineral interactions also enabled sequential nanoparticle release during acid-triggered crystal dissolution.
Researchers developed an organelle-mimetic ZIF-67/CoS/CdS nanoreactor that directs photogenerated charges to co-produce hydrogen and selectively convert lactic acid into pyruvic acid. The catalyst maintained strong performance under natural sunlight and at a 1000 cm² reaction area, supporting further development of scalable solar-driven chemical production.
PI (Physik Instrumente), a leading manufacturer of high precision air bearings, motion control and nanopositioning systems, offers a new overload protection for its compact H-811 hexapod.
Researchers developed magnetically driven 2D MXene microrobots that capture and retrieve PS and PET microplastics from laboratory water and soil samples. In 60-minute tests, the microrobots removed up to 94.0% of microplastics from water and 80.6% from soil, but nickel leakage and incomplete recovery require further study.
