Published 2023 Rolling Hills Estates landslide likely began the winter before
(via sciencedaily.com) Original source Landslides triggered by intense rainfall can sometimes be predicted along with incoming storms, but dry-season landslides often take people by surprise. The July 2023 Rolling Hills Estates landslide that destroyed 12 homes seemed to come out of nowhere, but new research shows it began as early as December 2022. Researchers are developing a database that will enable scientists to plug in new data to monitor potential landslides in real time and possibly predict them.
Published A new material derived from graphene improves the performance of neuroprostheses
(via sciencedaily.com) Original source Neuroprostheses allow the nervous system of a patient who has suffered an injury to connect with mechanical devices that replace paralyzed or amputated limbs. A study demonstrates in animal models how EGNITE, a derivative of graphene, allows the creation of smaller electrodes, which can interact more selectively with the nerves they stimulate, thus improving the efficacy of the prostheses.

(via sciencedaily.com) Original source Layers of carbon atoms in a honeycomb array are a true supermaterial: their unusually high conductivity and favorable mechanical properties could further the development of bendable electronics, new batteries, and innovative composite materials for aeronautics and space flight. However, the development of elastic and tough films remains a challenge. A research team has now introduced a method to overcome this hurdle: they linked graphene nanolayers via 'extendable' bridging structures.
Published Towards next-gen functional materials: direct observation of electron transfer in solids
(via sciencedaily.com) Original source Nanoscale electron transfer (ET) in solids is fundamental to the development of multifunctional materials. However, ET in solids is not yet clearly understood. Now, researchers achieved a direct observation of solid-state ET through X-ray crystal analysis by fabricating a novel double-walled non-covalent crystalline nanotube, which can absorb electron donor molecules and maintain its crystalline structure during ET. This innovative approach can lead to the design of novel functional materials soon.
