PI (Physik Instrumente), a global leader in precision motion control and nanopositioning technology, offers the P-733 XYZ piezo nanopositioning stage, delivering 0.1 nm (1 Å) positioning resolution for demanding applications in super-resolution microscopy, atomic force microscopy (AFM), surface nanometrology, and advanced imaging.
Researchers developed a potentially scalable metallurgical route that converts crystalline boron into dispersible, amorphous B/O-rich two-dimensional nanosheets through lithium alloying, chemical delithiation, and exfoliation. The nanosheets were incorporated into solution-processed SiC composite coatings with high solar absorptance, highlighting their potential for energy and photonic applications.
Biomass-derived green nanomaterials offer a renewable approach to removing persistent pollutants through adsorption, catalytic degradation, and redox reactions while reducing reliance on hazardous synthesis chemicals. The review reports promising removal efficiencies for heavy metals, dyes, and pesticides but highlights unresolved challenges involving scalability, real-world performance, reusability, environmental fate, and nanotoxicity.
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.
