A research team has developed an optimal artificial intelligence model to predict the yield strength of various metals, effectively addressing traditional cost and time limitations.
Published Materials research revolutionized by a small change (via sciencedaily.com) Original source
Scientists develop the next generation of highly efficient memory materials with atom-level control.
Published Microrobot-packed pill shows promise for treating inflammatory bowel disease in mice (via sciencedaily.com) Original source
Engineers have developed a pill that releases microscopic robots, or microrobots, into the colon to treat inflammatory bowel disease (IBD). The experimental treatment, given orally, has shown success in mice. It significantly reduced IBD symptoms and promoted the healing of damaged colon tissue without causing toxic side effects.
Published A new study highlights potential of ultrafast laser processing for next-gen devices (via sciencedaily.com) Original source
A new study uncovers the remarkable potential of ultrafast lasers that could provide innovative solutions in 2D materials processing for many technology developers such as high-speed photodetectors, flexible electronics, biohybrids, and next-generation solar cells.
Published Revealing the dynamic choreography inside multilayer vesicles (via sciencedaily.com) Original source
Our cells and the machinery inside them are engaged in a constant dance. This dance involves some surprisingly complicated choreography within the lipid bilayers that comprise cell membranes and vesicles -- structures that transport waste or food within cells. In a recent paper, researchers shed some light on how these vesicles self-assemble, knowledge that could help scientists design bio-inspired vesicles for drug-delivery or inspire them to create life-like synthetic materials.
Published Researchers film energy materials as they form (via sciencedaily.com) Original source
Shooting a movie in the lab requires special equipment. Especially when the actors are molecules -- invisible to the naked eye -- reacting with each other. 'Imagine trying to film tiny lava flows during a volcanic eruption. Your smartphone camera wouldn't be up to the job.
Published Novel method for measuring nano/microplastic concentrations in soil using spectroscopy (via sciencedaily.com) Original source
Current techniques for measuring nano/microplastic (N/MP) concentrations in soil require the soil organic matter content to be separated and have limited resolution for analyzing N/MPs sized <1 m. Therefore, researchers have developed a novel yet simple method to measure N/MP concentration in different soil types using spectroscopy at two wavelengths. This method does not require the soil to be separated in order to detect the N/MPs and can accurately quantify N/MPs regardless of their size.
Published Golden ball mills as green catalysts (via sciencedaily.com) Original source
A gold-coated milling vessel for ball mills proved to be a real marvel: without any solvents or environmentally harmful chemicals, the team was able to use it to convert alcohols into aldehydes. The catalytic reaction takes place at the gold surface and is mechanically driven. The vessel can be reused multiple times. 'This opens up new prospects for the use of gold in catalysis and shows how traditional materials can contribute to solving modern environmental problems in an innovative way,' says Borchardt.
Published Nano-immunotherapy developed to improve lung cancer treatment (via sciencedaily.com) Original source
Researchers have developed a new nanomedicine therapy that delivers anticancer drugs to lung cancer cells and enhances the immune system's ability to fight cancer. The team showed promising results for the new therapy in cancer cells in the lab and in mouse lung tumor models, with potential applications for improving care and outcomes for patients with tumors that have failed to respond to traditional immunotherapy.
Published Self-assembling and disassembling swarm molecular robots via DNA molecular controller (via sciencedaily.com) Original source
Researchers have succeeded in developing a DNA-based molecular controller. Crucially, this controller enables the autonomous assembly and disassembly of molecular robots, as opposed to manually directing it.
Published Nanosized blocks spontaneously assemble in water to create tiny floating checkerboards (via sciencedaily.com) Original source
Researchers have engineered nanosized cubes that spontaneously form a two-dimensional checkerboard pattern when dropped on the surface of water. The work presents a simple approach to create complex nanostructures through a technique called self-assembly.
