May 19, 2022 (Nanowerk News) Glioblastomas (GBMs) are highly aggressive cancerous tumors of the brain and spinal cord. Brain cancers like GBM are challenging to treat because many cancer therapeutics cannot pass through the blood-brain barrier, and more than 90 percent of GBM tumors return after being surgically removed, despite...
a bond between David and Goliath
May 19, 2022 (Nanowerk News) When single particles like atoms and ions bond, molecules emerge. Such bonds between to particles can arise if they have for example opposite electrical charges and hence attract each other. The molecule observed at the University of Stuttgart exhibits a special feature: It consists of...
Accelerating the pace of machine learning
May 19, 2022 (Nanowerk News) Machine learning happens a lot like erosion. Data is hurled at a mathematical model like grains of sand skittering across a rocky landscape. Some of those grains simply sail along with little or no impact. But some of them make their mark: testing, hardening, and...
Ultrahigh piezoelectric performance demonstrated in ceramic materials
May 18, 2022 (Nanowerk News) The ability of piezoelectric materials to convert mechanical energy into electrical energy and vice versa makes them useful for various applications from robotics to communication to sensors. A new design strategy for creating ultrahigh-performing piezoelectric ceramics opens the door to even more beneficial uses for...
Synthesis of two-dimensional holey graphyne
May 18, 2022 (Nanowerk News) Diamond and graphite are two naturally occurring carbon allotropes that we have known for thousands of years. They are elemental carbons that are arranged in a manner so that they consist of sp3 and sp2 hybridized carbon atoms, respectively. More recently, the discovery of various...
Researchers create photonic materials for powerful, efficient light-based computing
May 18, 2022 (Nanowerk News) University of Central Florida researchers are developing new photonic materials that could one day help enable low power, ultra-fast, light-based computing. The unique materials, known as topological insulators, are like wires that have been turned inside out, where the current runs along the outside and...
Hyperfast white dwarfs moving like billiard balls may change understanding of supernovae
May 18, 2022 (Nanowerk News) “Understanding the origin of type Ia supernovae has been one of the highly debated questions in astrophysics,” explains Dr. Samar Safi-Harb, the Natural Sciences and Engineering Research Council (NSERC) Tier 1 Canada Research Chair in Extreme Astrophysics at the University of Manitoba. Safi-Harb is working...
Study shows ultrafast dynamics of electron orbitals in molecules
May 18, 2022 (Nanowerk News) Researchers from Universität Hamburg, European XFEL and DESY have succeeded in looking at details of molecular orbitals at DESY's free-electron laser FLASH. The team reports in the journal Nature Communications ("Ultrafast orbital tomography of a pentacene film using time-resolved momentum microscopy at a FEL") on...
The colors of hydrogen explained
May 18, 2022 (Nanowerk News) Hydrogen has emerged as the energy technology that could help nations like Australia to decarbonise their economies. But did you know that, beyond green and blue hydrogen, there’s a whole rainbow of hydrogen types? Swinburne University of Technology’s Victorian Hydrogen Hub (VH2) is delving deeper...
Remarkable ‘cosmic telescope’ reveals inner workings of two proto-galaxies
May 18, 2022 (Nanowerk News) Using a unique new instrument and a little help from nature, Swinburne University of Technology researchers have gotten the first in-depth view of the enormous gas clouds that serve as galactic nurseries. Working internationally with researchers from North Carolina State University and the W.M. Keck...
