Jul 17, 2023 (Nanowerk News) Chronic inflammatory bowel disease (IBD), such as Crohn’s disease and ulcerative colitis, is on the rise worldwide. The benefits of current medications are limited by problematic side effects. In the journal Angewandte Chemie ("Anti-inflammatory Glycocalyx-Mimicking Nanoparticles for Colitis Treatment: Construction and In Vivo Evaluation"), a...

Jul 17, 2023 (Nanowerk News) Rice University engineers have created containers that can keep volatile organic compounds (VOCs) from accumulating on the surfaces of stored nanomaterials. The portable and inexpensive storage technology addresses a ubiquitous problem in nanomanufacturing and materials science laboratories and is described in a paper published in...

Jul 17, 2023 (Nanowerk News) Small-angle scattering of x-rays and neutrons is a useful tool for studying molecular and nanoparticle structures. So far, however, experiments have revealed a surprising lack of nanoparticle structure in certain nanocomposite materials – whose molecular skeletons are reinforced with nanoparticles previously treated with polymer adsorption....

Jul 17, 2023 (Nanowerk Spotlight) The field of flexible electronics has witnessed a significant surge in recent years, driven by the increasing demand for portable and wearable devices, soft robotics, biomedical equipment, and human-machine interfaces. However, the conventional plastic-based electronics that have dominated the market are raising serious ecological concerns....

Jul 13, 2023 (Nanowerk News) New research sheds light on the mechanism behind how a special material changes from an electrically conducting metal to an electric insulator. The researchers studied lanthanum strontium nickel oxide (La1.67Sr0.33NiO4) derived from a quantum material La2NiO4. Quantum materials have unusual properties that result from how...

Jul 13, 2023 (Nanowerk News) The π-π interaction is a type of noncovalent interaction that occurs when the electron clouds in the π orbitals of aromatic rings or π-conjugated molecular systems overlap. This interaction enables an efficient movement of electrons between the molecules, offering the potential to design materials with...

Jul 14, 2023 (Nanowerk News) Several studies have predicted that the water splitting reaction could be catalysed by certain groups of 2D materials – each measuring just a few atoms thick. One particularly promising group are named 2D Janus materials, whose two sides each feature a different molecular composition. Through...

Jul 14, 2023 (Nanowerk News) Although grasping objects is a relatively straightforward task for us humans, there is a lot of mechanics involved in this simple task. Picking up an object requires fine control of the fingers, of their positioning, and of the pressure each finger applies, which in turn...

Jul 13, 2023 (Nanowerk News) Defying conventional wisdom, researchers have uncovered a novel coupling mechanism involving leaky mode, previously has been considered unsuitable for high-density integration in photonic circuits. This unexpected finding opens new possibilities for dense photonic integration, revolutionizing the scalability and application of photonic chips in optical computing,...

Jul 14, 2023 (Nanowerk News) Liquid metal, planet-like nanodroplets are successfully formed with a new technique developed at RMIT University, Australia. Like our own Planet Earth, the nanodroplets feature an outer ‘crust’, a liquid metal ‘mantle’, and a solid ‘core’. The solid intermetallic core is the key to achieving a...
