New light-activated electron pathway found in nanotubes
Jun 07, 2024 (Nanowerk News) Research groups led by the University of Tsukuba and the University of Rennes have unveiled a unique phenomenon where, upon exposure to light, a nested structure of carbon nanotubes enveloped in boron nitride nanotubes allows for a peculiar electron escape route. This discovery opens up...
With programmable pixels, novel sensor improves imaging of neural activity
Jun 07, 2024 (Nanowerk News) Neurons communicate electrically so to understand how they produce brain functions such as memory, neuroscientists must track how their voltage changes—sometimes subtly—on the timescale of milliseconds. In a new paper in Nature Communications ("Pixel-wise programmability enables dynamic high-SNR cameras for high-speed microscopy"), MIT researchers describe...
Machine learning revolutionizes simulation of metal-organic frameworks (MOFs)
Jun 06, 2024 (Nanowerk News) Hydrogen storage, heat conduction, gas storage, CO2 and water sequestration – metal-organic frameworks (MOFs) have extraordinary properties due to their unique structure in the form of microporous crystals, which have a very large surface area despite their small size. This makes them extremely interesting for...

Jun 06, 2024 (Nanowerk News) A research team led by the School of Engineering of the Hong Kong University of Science and Technology (HKUST) has developed a liquid metal-based electronic logic device that mimics the intelligent prey-capture mechanism of Venus flytraps. Exhibiting memory and counting properties, the device can intelligently...
New cathode structure boosts stability and performance of sodium-ion batteries
Jun 07, 2024 (Nanowerk Spotlight) Lithium-ion batteries, with their high energy density and long lifetimes, have dominated the rechargeable battery market for decades. However, lithium's scarcity and rising cost have spurred an intense search for alternative battery chemistries using more abundant materials. Sodium, right below lithium on the periodic table,...
Molecular templating converts 2D metal halide perovskites to 1D nanowires
Jun 06, 2024 (Nanowerk News) Purdue University engineers have developed a patent-pending method to synthesize high-quality, layered perovskite nanowires with large aspect ratios and tunable organic-inorganic chemical compositions. Letian Dou, the Charles Davidson Associate Professor of Chemical Engineering in the College of Engineering and associate professor of chemistry, by courtesy,...
‘Artificial lymph node’ used to treat cancer in mice
Jun 06, 2024 (Nanowerk News) Johns Hopkins Medicine scientists say they have developed an artificial lymph node with the potential to treat cancer, according to a new study in mice and human cells. The newly developed lymph node — a sac filled with immune system components — is implanted under...
