Most farming regions that experience severe droughts have abundant brackish water aquifers that are too expensive to access. Membrion’s Ceramic Ion Exchange Membranes, made from silica gel, the desiccant in the bottom of a beef jerky package, provide a 30% reduction to the levelized cost of brackish water purification compared to the gold standard currently…

By Chris Adam, [email protected] Purdue University innovators are taking cues from nature to develop 3D photodetectors for biomedical imaging. The Purdue researchers used some architectural features from spider webs to develop the technology. Spider webs typically provide excellent mechanical adaptability and damage-tolerance against various mechanical loads such as storms. “We employed the unique fractal design…

Pacific Northwest National Laboratory’s transformative Self-Healing Cement fills cracks and restores cement to its original mechanical integrity in intense, high-temperature environments. The combination of synthetic polymer and cement outperforms conventional concrete. The pollution-preventing technology extends the life of cement by at least 30 years. The cement also reduces drilling interruptions and costly repairs. Self-healing cement…

By Karen K Dunlap Scientists at Oak Ridge National Laboratory and the University of Tennessee designed and demonstrated a method to make carbon-based materials that can be used as electrodes compatible with a specific semiconductor circuitry. The work bridges nanoscale 3D printing and widely available processes for complementary metal-oxide-semiconductor, or CMOS, technologies to enable biosensors…

By varying the energy and dose of tightly focused electron beams, researchers have demonstrated the ability to both etch away and deposit high-resolution nanoscale patterns on two-dimensional layers of graphene oxide. The 3D additive/subtractive “sculpting” can be done without changing the chemistry of the electron beam deposition chamber, providing the foundation for building a new…

By Diana Anderson Vehicles powered by polymer electrolyte membrane fuel cells (PEMFCs) are energy-efficient and eco-friendly, but despite increasing public interest in PEMFC-powered transportation, current performance of materials that are used in fuel cells limits their widespread commercialization. Scientists at the U.S. Department of Energy’s (DOE) Argonne National Laboratory led a team to investigate reactions…

By Jennifer Chu | MIT News Office MIT engineers have designed a Velcro-like food sensor, made from an array of silk microneedles, that pierces through plastic packaging to sample food for signs of spoilage and bacterial contamination. The sensor’s microneedles are molded from a solution of edible proteins found in silk cocoons and are designed…

Researchers at the Department of Energy’s Oak Ridge National Laboratory used quantum optics to advance state-of-the-art microscopy and illuminate a path to detecting material properties with greater sensitivity than is possible with traditional tools. “We showed how to use squeezed light – a workhorse of quantum information science – as a practical resource for microscopy,”…

by University of California San Diego Scientists at UC San Diego have discovered a new anode material that enables lithium-ion batteries to be safely recharged within minutes for thousands of cycles. Known as a disordered rocksalt, the new anode is made up of earth-abundant lithium, vanadium and oxygen atoms arranged in a similar way as…

By Chris Adam Purdue University researchers have passed another significant milestone as they work to take a new two-dimensional nanomaterial to market for use in nanoelectronics, quantum devices and infrared technology used in national defense tools and biochemical sensors. The Purdue team received a U.S. patent for the nanomaterial, derived from the rare element tellurium,…

by Cornell University A Cornell University-led collaboration has created the first microscopic robots that incorporate semiconductor components, allowing them to be controlled – and made to walk – with standard electronic signals. These robots, roughly the size of paramecium, provide a template for building even more complex versions that utilize silicon-based intelligence, can be mass…

by Theresa Duque (Adapted from news release by Robert Perkins, Caltech) The quest for renewable fuels harvested from the sun continues, as the U.S. Department of Energy (DOE) has announced two new major awards focused on advancing artificial photosynthesis technologies for the production of fuels from sunlight. As part of this effort, DOE has awarded…

A team of scientists at the University of Southampton have established significant results in the elimination of Covid-19 within minutes, on a copper-based alloy, demonstrating its ability to reduce coronavirus transmission rates, via commonly touched surfaces, manufactured with this metal. Working with Sylatech, an engineering business in North Yorkshire, U.K., Professor Bill Keevil, Dr. SandraWilks…

By Lee Teschler Engineers trying to shield RF-sensitive circuitry a few years from now may have the option of using material that absorbs RF energy rather than just reflecting it. So say researchers at Drexel University and the Korea Institute of Science and Technology. They are researching a class of material called MXenes, and more…

By Lee Teschler If you’ve used an ink-jet printer or a tiny hearing aid, chances are those devices have employed lead-zirconium-titanium oxide (PZT, Pb(Zr,Ti)O3) piezoelectric ceramics as a means of generating ink droplets and amplified audio. These and numerous other applications have long used actuators and sensors employing piezoelectric materials which deform in response to…

Researchers at the U.S. Department of Energy’s (DOE) Argonne National Laboratory, in conjunction with industry partner Sentient Science, are making the discovery and design of new materials — a notoriously time-consuming and costly process — significantly easier through the development of an artificial intelligence-based computer modeling framework. The research was awarded $150,000 through the DOE’s…

The discovery of green fluorescent protein (GFP), which is made by a jellyfish, transformed cell biology.
