Mar 04, 2022 (Nanowerk News) A research team at the Leibniz Institute for Natural Product Research and Infection Biology - Hans Knöll Institute (Leibniz-HKI) in Jena, Germany has developed a new method to produce complex natural products in amoebae. These polyketides include various antibiotics but also olivetolic acid, a precursor...
building precise smaller nanoparticles with templates
Mar 04, 2022 (Nanowerk News) Nanoparticles (which have sizes ranging between 3–500 nm), and sub-nanoclusters (which are around 1 nm in diameter) are utilized in many fields, including medicine, robotics, materials science, and engineering. Their small size and large surface-area-to-volume ratios give them unique properties, rendering them valuable in a...
Artificial intelligence predicts algae potential as alternative energy source
Mar 04, 2022 (Nanowerk News) Texas A&M AgriLife Research scientists are using artificial intelligence to set a new world record for producing algae as a reliable, economic source for biofuel that can be used as an alternative fuel source for jet aircraft and other transportation needs. Joshua Yuan, Ph.D., AgriLife...
Robot ‘bugs’ that can go just about anywhere
Mar 04, 2022 (Nanowerk News) These ancient creatures can squeeze through the tiniest cracks, fit snugly into tight spaces and survive in harsh environments: There aren’t many spaces that are off-limits to an insect. That’s why researchers at the University of Pittsburgh have created tiny bug-inspired robots that can carry...
Producing ethylene from food waste without greenhouse gas emissions
Mar 04, 2022 (Nanowerk News) The Korea Institute of Science and Technology (KIST) announced that a research team led by Dr. Jeong-Myeong Ha of the Clean Energy Research Center developed a process technology and catalyst for removing hydrogen sulfide, a toxic substance, during the process of ethylene production from methane...
Form-free metasurfaces enable novel and intelligent optical illusion
Mar 04, 2022 (Nanowerk News) The scientific community has always been enthralled in the creation of an illusion – the optical transformation of an object into another object. So far, scientists experimenting with metamaterials in 'ghosting' have not had much success in changing the perception of the real object. Mainstream...
Researchers produce fully functional pancreatic beta cells from stem cells for the first time
Mar 04, 2022 (Nanowerk News) Insulin is a vital hormone produced by pancreatic beta cells. Type 1 diabetes is caused by the destruction of these cells, which results in patients having to replace the lost insulin with multiple daily injections. Insulin secretion can be restored in diabetic patients by transplanting...
Nanomodulators of light on optical micro-probes to study the brain
Mar 03, 2022 (Nanowerk News) When it comes to recording and stimulating brain activity, scientists can rely on a formidable tool: light. An international research team, coordinated by IIT- Istituto Italiano di Tecnologia (Italian Institute of Technology), has developed nanometric light modulators that, fabricated on a micrometric optical fiber, make...
Slightly twisted 2D semiconductors display room-temperature ferroelectricity
Mar 03, 2022 (Nanowerk News) A team of researchers at The University of Manchester’s National Graphene Institute (NGI) and the National Physical Laboratory (NPL) has demonstrated that slightly twisted 2D transition metal dichalcogenides (TMDs) display room-temperature ferroelectricity. This characteristic, combined with TMDs’ outstanding optical properties, can be used to build...
Could DNA nanodevices be used to treat cancer?
Mar 03, 2022 (Nanowerk News) One of the most promising avenues in treating cancer is to restore our immune system’s ability to recognize and attack cancerous cells. A team of University of Chicago chemists and biologists developed a tiny device that can locate tumor cells and force them to reveal...
