Researchers developed a sacrificial-template porous silica thin film for electrochemically directed oligonucleotide synthesis that increased the available reaction area while preserving localized electrochemical control. The platform supported parallel synthesis of 121-nucleotide strands and recovery of an encoded 60-byte message, while highlighting remaining challenges in synthesis fidelity, parallelism, and cost.
Researchers used spatiotemporal terahertz emission nanoscopy to map the electromagnetic signatures of ultrafast spin-driven charge currents in a fiber-coupled spintronic terahertz emitter with femtosecond temporal resolution and nanoscale spatial sensitivity. The study shows how localized in-plane currents produce detectable out-of-plane electric fields, clarifying how near-field terahertz measurements can probe ultrafast spin-to-charge transport.
Most of today's computer chips — also sometimes known as conventional integrated circuits — use electrons to deliver their signals via semiconductor materials and metallic components. In contrast, photonic integrated circuits use faster signal carriers, such as photons or quantized "light particles."
Motion control specialist PI has released the new H-855 high-load hexapod robot family, a new modular 6-DOF positioning platform designed to precisely position and align payloads weighing up to 500 kg (1100 lbs).
Researchers engineered a stretchable pressure-sensitive composite that combines carbon nanofibers and carbon black nanoparticles in PDMS to tune sensitivity, sensing range, and resistance response. They integrated the material into flexible sensor arrays and paired it with circuit modeling and normalization to reduce crosstalk and track spatial pressure patterns and handwritten trajectories.
Anton Paar introduces the new UNHT Series, a new generation of nanoindentation systems designed to deliver reliable results, faster workflows, and greater versatility across a wide range of materials.
Researchers built an InSb-lithium niobate acoustoelectric current source that converts RF-driven surface acoustic waves directly into DC, with a wired output tunable from 1.22 nA to 25.46 µA and stable operation over 12 hours. The same platform also operated under wireless RF excitation and was tested for low-current stimulation in a rat wound model, although its RF-to-DC efficiency remains far below that of conventional rectifiers.
Researchers developed a thermal interface fluorofluidic gel whose hydrogen-bonding nanoclusters enable it to transition from a quasi-solid to a more fluidic state as temperature rises, helping the material conform to rough interfaces while retaining adhesion, mechanical resistance, and electrical insulation. The optimized TIF0.25 formulation reached a thermal conductivity of 5.89 W·m?¹·K?¹ at 60 wt% filler and a contact thermal resistance of 0.15 cm²·K·W?¹ at 50 psi, while maintaining performance through 1,000 thermal cycles.
After a decade of development support, PI's hexapods and PICMA piezo actuators are now flying on NASA's Roman Space Telescope, launched August 2026.
PI (Physik Instrumente) has extended its BIX bi-phase piezo drive beyond the original B-421 stage, adding high-force, rotary, screw-drive, tip/tilt, and cryogenic variants for nanopositioning OEMs.
