Jan 16, 2024 (Nanowerk News) The scientific community has long been enamored of the potential for soft bioelectronic devices, but has faced hurdles in identifying materials that are biocompatible and have all of the necessary characteristics to operate effectively. Researchers have now taken a step in the right direction, modifying...

Jan 16, 2024 (Nanowerk News) “Soft robots,” medical devices and implants, and next-generation drug delivery methods could soon be guided with magnetism—thanks to a metal-free magnetic gel developed by researchers at the University of Michigan and the Max Planck Institute for Intelligent Systems in Stuttgart, Germany. The material is the...

Jan 16, 2024 (Nanowerk News) Very strong, light materials that can withstand extremely high temperatures could usher in next-generation spacecraft, enhance current devices or enable the development of new biomedical imaging or hydrogen storage applications, among others. To this end, Rice University scientists in the lab of Angel Martí have...

Jan 16, 2024 (Nanowerk News) A key chemical reaction — in which the movement of protons between the surface of an electrode and an electrolyte drives an electric current — is a critical step in many energy technologies, including fuel cells and the electrolyzers used to produce hydrogen gas. For...

Jan 16, 2024 (Nanowerk Spotlight) Scientists have long explored using light to precisely control molecular-scale machines inside living cells for applications like targeted drug delivery. However, progress in this promising field has been incremental. Early light-sensitive molecular actuators were structurally too simple to produce meaningful mechanical motions in complex intracellular...

Jan 16, 2024 (Nanowerk News) Researchers from Osaka University and collaborating partners have improved the efficiency of heat-to-electricity conversion in gallium arsenide semiconductor microstructures. By judicious spatial alignment of electrons within a two-dimensional electron gas system with multiple subbands, one can substantially enhance the power factor compared with previous iterations...

Jan 16, 2024 (Nanowerk News) Not every wound can be closed with needle and thread. Empa researchers have now developed a soldering process with nanoparticles that gently fuses tissue. The soldering technique is expected to prevent wound healing disorders and life-threatening complications from leaking sutures. The team recently published the...

Jan 16, 2024 (Nanowerk News) A KAIST research team has developed an anti-icing and de-icing film coating technology that can apply the photothermal effect of gold nanoparticles to industrial sites without the need for heating wires, periodic spray or oil coating of anti-freeze substances, and substrate design alterations. The group...

Jan 15, 2024 (Nanowerk Spotlight) Ammonia is indispensable for producing the fertilizers and chemicals that sustain food and material production for billions globally. However, conventional industrial scale ammonia synthesis comes at great environmental costs. The predominant century-old Haber-Bosch method accounts for over 2% of energy use worldwide, while generating substantial...

Jan 15, 2024 (Nanowerk News) Memristive devices constitute a category of devices capable of retaining their internal resistance, thus offering superior performance compared to conventional devices that use integrated circuits. Several materials have been explored to manufacture these devices. In recent years, transition metal oxides have gradually become widely popular...
