May 31, 2023 (Nanowerk News) Scientists have developed an advanced technique for 3D printing that is set to revolutionise the manufacturing industry. The group, led by Dr Jose Marques-Hueso from the Institute of Sensors, Signals & Systems at Heriot-Watt University in Edinburgh, has created a new method of 3D printing...
Flexible electronic nanomembranes can advance organ-on-chip technology
May 31, 2023 (Nanowerk News) Engineers from UNSW Sydney have discovered a way to create flexible electronic systems on ultra-thin skin-like materials. The development allows entire stretchable 3D structures to operate like a semiconductor and could help significantly reduce the need for animal testing by making so-called organ-on-chip technology more...
You can make carbon dioxide filters with a 3D printer
May 31, 2023 (Nanowerk News) In a new study, North Carolina State University researchers demonstrated that it’s possible to make carbon dioxide capture filters using 3D printing. Specifically, they printed a hydrogel material that can hold carbonic anhydrase, an enzyme that speeds a reaction that turns carbon dioxide and water...
The world’s fastest electron microscope
May 31, 2023 (Nanowerk News) Electron microscopes give us insight into the tiniest details of materials and can visualize, for example, the structure of solids, molecules or nanoparticles with atomic resolution. However, most materials in nature are not static. They constantly interact, move and reshape between initial and final configurations....
Nanoparticles deliver brain cancer treatment
May 31, 2023 (Nanowerk News) University of Queensland researchers have developed a nanoparticle to take a chemotherapy drug into fast growing, aggressive brain tumours. The study is published in the Journal of Controlled Release ("Efficient delivery of Temozolomide using ultrasmall large-pore silica nanoparticles for glioblastoma"). Research team lead Dr Taskeen...
Metal shortage could put the brakes on electrification
May 31, 2023 (Nanowerk News) Electrification and digitalisation are leading to a steady increase in the need for critical metals* in the EU’s vehicle fleet. Moreover, only a small proportion of the metals are currently recycled from end-of-life vehicles. The metals that are highly sought after, such as dysprosium, neodymium,...
A telescope’s last view
May 30, 2023 (Nanowerk News) More than 5,000 planets are confirmed to exist beyond our solar system. Over half were discovered by NASA’s Kepler Space Telescope, a resilient observatory that far outlasted its original planned mission. Over nine and a half years, the spacecraft trailed the Earth, scanning the skies...
Webb maps surprisingly large plume jetting from Saturn’s moon Enceladus
May 30, 2023 (Nanowerk News) A water vapor plume from Saturn’s moon Enceladus spanning more than 6,000 miles – nearly the distance from Los Angeles, California to Buenos Aires, Argentina – has been detected by researchers using NASA’s James Webb Space Telescope. Not only is this the first time such...
Artificial virus-like particle could be harnessed to improve human health
May 30, 2023 (Nanowerk News) International researchers have built artificial virus-like particles capable of entering human cells to perform tasks such as gene editing. In a proof of concept study, the team used a type of virus that infects bacteria to design a method of building artificial viral vectors, or...
Flexible nanoelectrodes can provide fine-grained brain stimulation
May 30, 2023 (Nanowerk News) Conventional implantable medical devices designed for brain stimulation are often too rigid and bulky for what is one of the body’s softest and most delicate tissues. To address the problem, Rice University engineers have developed minimally invasive, ultraflexible nanoelectrodes that could serve as an implanted...
