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...
Researchers design highly sensitive, mass producible organic photodetectors
Aug 25, 2022 (Nanowerk News) Researchers have developed and demonstrated new green-light absorbing transparent organic photodetectors that are highly sensitive and compatible with CMOS fabrication methods. Incorporating these new photodetectors into organic-silicon hybrid image sensors could be useful for applications such as light-based heart-rate monitoring, fingerprint recognition and devices that...
Nontoxic nanocrystal material found to be ultra-strong solar energy harvester
Aug 25, 2022 (Nanowerk News) Solar cells are vital for the green energy transition. They can be used not only on rooftops and solar farms but also for powering autonomous vehicles, such as planes and satellites. However, photovoltaic solar cells are currently heavy and bulky, making them difficult to transport...
A faster way to study 2D materials for next-generation quantum and electronic devices
Aug 25, 2022 (Nanowerk News) Two-dimensional materials, which consist of a single layer of atoms, exhibit unusual properties that could be harnessed for a wide range of quantum and microelectronics systems. But what makes them truly special are their flaws. “That’s where their true magic lies,” said Alexander Weber-Bargioni at...
Understanding outsize role of nanopores
Aug 25, 2022 (Nanowerk News) There is an entire aqueous universe hidden within the tiny pores of many natural and engineered materials. Research from the McKelvey School of Engineering at Washington University in St. Louis has shown that when such materials are submerged in liquid, the chemistry inside the tiny...
