This review finds that copper nanoparticles can enhance the performance of vegetable oils as bio-lubricants by reducing friction and wear through rolling, surface repair, and protective tribofilm formation. The authors caution that real-world adoption will depend on improved dispersion stability, optimized nanoparticle design, standardized testing, life-cycle assessment, and durability studies.
Polymer nanoparticles formed by polymerization-induced self-assembly inhibited ice recrystallization primarily through their internal hydrophobic cores rather than their outer hydrophilic coronas. Soft, mobile cores suppressed ice growth more effectively than rigid cores, while core crosslinking reduced activity, suggesting core dynamics as a design lever for synthetic cryoprotectants.
Researchers developed a voltage-directed one-pore synthesis method to form ultrathin alginate ionic nanogels inside solid-state silicon nitride nanopores. By tuning phosphate additives, metal-ion crosslinkers, and gate voltages, the nanogels combined strong ion selectivity with high pore-area-normalized osmotic power density.
Whether inspecting semiconductor wafers, measuring optical components, or imaging biological samples, the quality of the data depends on maintaining perfect focus.
Researchers introduced TFM-IR, an ambient-condition infrared microscopy method that uses torsional cantilever dynamics and nonlinear frequency mixing to map in-plane and out-of-plane photothermal responses at the nanoscale. The technique resolved anisotropic strain in mica nanobubbles and achieved near-nanometer optical imaging in twisted bilayer graphene, enabling site-resolved spectroscopy within individual moiré cells.
A new study finds that nanomaterial-based batteries could help Italy store more renewable energy by improving energy density, charging speed, cycle life, and safety. However, high costs, weak coordination, regulatory delays, and low stakeholder awareness are slowing the shift from laboratory research to market deployment.
PI (Physik Instrumente), a global leader in precision motion control and nanopositioning technologies, announces the H-850.
A review in Advanced Sustainable Systems examines how metalloproteins, ferritins, virus-like particles, and de novo designed protein cages could help trap, transform, and immobilize toxic metals and metalloids. The paper highlights protein engineering, synthetic biology, and AI-guided design as promising routes toward more selective, reusable, and sustainable bioremediation systems.
PEI-functionalized magnetic carbon nanoparticles achieved 98.33% water removal from water-in-heavy oil emulsions within 60 minutes under optimized laboratory conditions. The material combined magnetic recoverability, carbon-based stability, and amine-rich surface chemistry to disrupt bitumen-stabilized interfacial films and promote droplet coalescence.
This JACS Au Perspective traces how DNA origami has advanced from programmable nanoscale shapes into dynamic, hybrid platforms for biosensing, drug delivery, optoelectronics, nanofabrication, and synthetic biology. The authors highlight major advances in design, computation, and biomedical research while emphasizing that stability, scalability, biosafety, immunogenicity, and manufacturing barriers continue to limit broader translation.
