Aug 26, 2022 (Nanowerk News) When you think of proteins – the enzymes, signaling molecules, and structural components in every living thing – you might think of single strands of amino acids, organized like beads on a string. But nearly all proteins consist of multiple strands folded up and bound...
Mimicking termites to generate new materials
Aug 26, 2022 (Nanowerk News) Inspired by the way termites build their nests, researchers at Caltech have developed a framework to design new materials that mimic the fundamental rules hidden in nature's growth patterns. The researchers showed that, using these rules, it is possible to create materials designed with specific...
Small molecules, giant (surface) potential
Aug 26, 2022 (Nanowerk News) In a molecular feat akin to getting pedestrians in a scramble crosswalk to spontaneously start walking in step, researchers at Kyushu University have created a series of molecules that tend to face the same direction to form a ‘giant surface potential’ when evaporated onto a...
Full experimental determination of tunneling time with attosecond-scale streaking method
Aug 26, 2022 (Nanowerk News) Timing photoionization is essential for our understanding of how light and matter interact on the most fundamental level. The advent of attosecond metrologies allows us to access the timing information on the natural scale of electrons in atoms and molecules. The attoclock is a powerful...
Glass nanoparticles show unexpected coupling when levitated with laser light
Aug 26, 2022 (Nanowerk News) A team of researchers at the University of Vienna, the Austrian Academy of Sciences and the University of Duisburg-Essen have found a new mechanism that fundamentally alters the interaction between optically levitated nanoparticles. Their experiment demonstrates previously unattainable levels of control over the coupling in...
Scientists develop new technique to reveal the hidden genome
Aug 25, 2022 (Nanowerk News) Using an innovative new technique, scientists at Duke-NUS Medical School and their collaborators have identified thousands of previously unknown DNA sequences in the human genome that code for microproteins and peptides potentially critical to human health and disease. “Much of what we understand about the...
Researchers develop new slippery surfaces for photocontrol of droplets
Aug 26, 2022 (Nanowerk News) A research team led by Dr. DU Xuemin from the Shenzhen Institute of Advanced Technology (SIAT), Chinese Academy of Sciences, has reported a new slippery material with superior light-induced charge regeneration capability, enabling photocontrol of droplets in various working scenarios. This work was published in...
The sands of Mars are green as well as red, rover Perseverance discovers
Aug 26, 2022 (Nanowerk News) The accepted view of Mars is red rocks and craters as far as the eye can see. That’s much what scientists expected when they landed the rover Perseverance in the Jezero Crater, a spot chosen partly for the crater’s history as a lake and as...
Scientists take control of magnetism at the microscopic level
Aug 26, 2022 (Nanowerk News) Atoms in magnetic materials are organized into regions called magnetic domains. Within each domain, the electrons have the same magnetic orientation. This means their spins point in the same direction. “Walls” separate the magnetic domains. One type of wall has spin rotations that are left-...
New granular hydrogel bioink could expand possibilities for tissue bioprinting
Aug 25, 2022 (Nanowerk News) Every day in the United States, 17 people die waiting for an organ transplant, and every nine minutes, another person is added to the transplant waiting list, according to the Health Resources and Services Administration. One potential solution to alleviate the shortage is to develop...
