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.
Researchers used sub-10-nm silver nanoparticles to bridge copper microparticles and silver nanoflakes, creating a micro-nano hybrid thermal interface material with a thermal conductivity of 330.0 W/(m·K).
In a model LED package, the nano-enabled hybrid reduced effective die-attach thermal resistance by 44% compared with a commercial silver paste while using less silver.
Researchers found that deep-sea carbonate fluorapatite comprises apatite nanocrystals embedded within an amorphous matrix that primarily hosts samarium, used as a probe for rare earth elements. This disordered nanoarchitecture helps explain why rare earth elements can be readily extracted by acid leaching despite fluorapatite’s low solubility.
A systematic review of 212 studies linked experimental exposure to microplastics and nanoparticles to oxidative stress, impaired growth and reproduction, and increased mortality across biological models. Smaller particles, higher concentrations, and polystyrene were associated with stronger effects, although laboratory conditions and limited human evidence restrict conclusions about real-world health risks.
A review proposes an integrated framework linking feedstock engineering, scalable processing, structural control, quality assurance, sustainability, and regulation to improve industrial nanocomposite production. It finds that AI, digital twins, real-time monitoring, and closed-loop control could improve production consistency, although data, validation, infrastructure, and standardization barriers still limit adoption.
Researchers showed that size-controlled lignin nanoparticles made from alkali and kraft lignins can improve enhanced oil recovery by lowering interfacial tension and shifting sandstone and carbonate rocks toward more water-wet conditions. The intermediate-sized alkali lignin nanoparticles delivered the strongest sandstone performance, with recovery gains linked to a balance between wettability alteration, interfacial activity, and pore-network transport.
Nanostructured titanium composites may enhance dental implants by providing antibacterial activity, enhanced bioactivity, corrosion protection, and localized drug-delivery capabilities. However, the review found that most evidence remains laboratory or preclinical, and long-term clinical studies are needed before these materials can move beyond established titanium implants.
Tescan has introduced the new generation of Tescan CLARA™, an ultra-high-resolution scanning electron microscope for nanoscale materials characterization.
