Pioneering noninvasive technique for neurological conditions Date posted July 07, 2021 kroy Mon, 07/19/2021 - 10:34 Funding Agency (Funded by the National Science Foundation and the U.S. Department of Defense) Researchers at Indiana University School of Medicine are developing a new brain stimulation technique to treat neurological disorders, including pain, traumatic brain injury, epilepsy, Parkinson's disease, and Alzheimer's disease. The technique uses a new type of magnetoelectric nanoparticles that can be delivered to a specific part of the brain using a magnetic field. The method is noninvasive and is more efficient than traditional methods of brain stimulation.

New microfluidic device delivers mRNA nanoparticles a hundred times faster Date posted July 07, 2021 kroy Mon, 07/19/2021 - 10:34 Funding Agency (Funded by the National Institutes of Health, the U.S. Department of Defense, and the National Science Foundation) Bioengineers and medical researchers at the University of Pennsylvania have designed a proof-of-concept microfluidic device containing 128 mixing channels working in parallel. The channels mix a precise amount of lipid and mRNA, crafting individual lipid nanoparticles on a miniaturized assembly line. The researchers tested the lipid nanoparticles produced by their device in a mouse study, showing that they could deliver therapeutic mRNA sequences with four-to-five times greater activity than those made by conventional methods.

Plant patch enables continuous monitoring for crop diseases Date posted July 07, 2021 kroy Mon, 07/19/2021 - 10:34 Funding Agency (Funded by the U.S. Department of Agriculture and the National Science Foundation) Researchers from North Carolina State University have developed a patch that plants can "wear" to monitor continuously for plant diseases or other stresses, such as crop damage or extreme heat. Plants emit different combinations of volatile organic compounds under different circumstances. The rectangular patch is 30 millimeters long and consists of a flexible material containing graphene-based sensors and flexible silver nanowires. By targeting volatile organic compounds that are relevant to specific diseases or plant stress, the sensors can alert users to specific problems.  Link https://news.ncsu.edu/2021/07/patch-monitoring-crop-diseases/

Tiny but mighty precipitates toughen a structural alloy Date posted July 08, 2021 kroy Mon, 07/19/2021 - 10:34 Funding Agency (Funded by the U.S. Department of Energy) Scientists at the U.S. Department of Energy's Oak Ridge National Laboratory and the University of Tennessee, Knoxville, have found a way to simultaneously increase the strength and ductility of an alloy by introducing nanoprecipitates into its matrix and tuning their size and spacing. The nanoprecipitates are nanometer-sized solids that separate from the metal mixture as the alloy cools. The researchers carefully kept the composition of the matrix and the total amount of nanoprecipitates the same in different samples. However, they varied nanoprecipitate sizes and spacings by adjusting the processing temperature and time. As a result, the strength of the alloy increased by 20%–90% and its elongation increased by 300%. Link https://neutrons.ornl.gov/content/tiny-mighty-precipitates-toughen-a-structural-alloy

Infrared cameras and artificial intelligence provide insight into boiling Date posted July 08, 2021 kroy Mon, 07/19/2021 - 10:34 Funding Agency (Funded by the U.S. Department of Energy and the National Science Foundation) A “boiling crisis” is the rapid formation of a vapor film between the heating source and the liquid when the heat supply exceeds a critical value. New research by engineers at MIT offers insight into the phenomenon by using high-speed infrared cameras and machine learning. The goal was to estimate how close the water was to a boiling crisis. To collect data, the engineers boiled water on a surface of indium tin oxide, by itself or with one of three coatings: copper oxide nanoleaves, zinc oxide nanowires, or layers of silicon dioxide nanoparticles. The team found that 17 factors contributed significantly to prediction accuracy. Link https://news.mit.edu/2021/infrared-cameras-artificial-intelligence-provide-insight-into-boiling-0707

Solving the plastic shortage with a new chemical catalyst Date posted July 08, 2021 kroy Mon, 07/19/2021 - 10:34 Funding Agency (Funded by the U.S. Department of Energy and the National Science Foundation) Researchers at the University of Michigan have developed a new chemical catalyst that could enable the production of more propylene, the feedstock for polypropylene, the world's second most widely used plastic. The new catalyst, which can make propylene from natural gas, is at least 10 times more efficient than current commercial catalysts and lasts 10 times longer before needing regeneration. It is made of platinum and tin nanoparticles supported by a framework of silica. Link https://news.umich.edu/solving-the-plastic-shortage-with-a-new-chemical-catalyst/

Harnessing the dark side Date posted July 13, 2021 kroy Mon, 07/19/2021 - 10:34 Funding Agency (Funded in part by the National Science Foundation and the U.S. Department of Defense) Optical singularities typically occur when the phase of light with a specific wavelength is undefined. These regions appear completely dark. Today, some optical singularities, including optical vortices, are being explored for use in optical communications and particle manipulation, but scientists are just beginning to understand the potential of these systems. Now, researchers from Harvard University have developed a new technique to control and shape optical singularities. To demonstrate their technique, the researchers created a singularity sheet in the shape of a heart by using flat metasurfaces with precisely shaped nanopillars to shape the singularities.
