A simpler way to inorganic perovskite solar cells
Apr 17, 2024 (Nanowerk News) Inorganic perovskite solar cells made of CsPbI3 are stable over the long term and achieve good efficiencies. A team led by Prof. Antonio Abate has now analysed surfaces and interfaces of CsPbI3 films, produced under different conditions, at BESSY II. The research has been published...
A new spin on materials analysis
Apr 17, 2024 (Nanowerk News) Researchers Koichiro Yaji and Shunsuke Tsuda at the National Institute for Materials Science in Japan have developed an improved type of microscope that can visualize key aspects of electron spin states in materials. The research has been published in Science and Technology of Advanced Materials:...
Paintable ‘second skin’ gel for wearable bioelectronic sensors
Apr 17, 2024 (Nanowerk Spotlight) Accurately monitoring the body's bioelectrical signals is crucial for cardiology research and clinical diagnosis of heart diseases. However, this requires customizable bioelectrodes that can adapt to the complex topography and movements of the skin. While electronic tattoos made of conductive materials like metals have been...
Unlocking multi-color ultra-long phosphorescence with carbonized polymer nanodots
Apr 17, 2024 (Nanowerk News) A research team led by JIANG Changlong from Hefei Institutes of Physical Science devised a novel method to prepare carbonized polymer nanodots capable of emitting multi-color ultra-long room-temperature phosphorescent (RTP) from blue to green. "These materials exhibit potential applications in anti-counterfeiting and information encryption," said...
Silver-based micromotors eliminate bacteria moving freely in aqueous media
Apr 17, 2024 (Nanowerk News) In ancient Greece, over 3000 years ago, wise men used silver salts to prevent wounds from becoming infected. These salts continued to be used until Alexander Fleming discovered the first antibiotic "just" 100 years ago. The use of antibiotics represented a major breakthrough in the...
Attosecond imaging made possible by short and powerful laser pulses
Apr 16, 2024 (Nanowerk News) Extremely short pulses of laser light with a peak power of 6 terawatts (6 trillion watts)—roughly equivalent to the power produced by 6,000 nuclear power plants—have been realized by two RIKEN physicists (Nature Photonics, "Dual-chirped optical parametric amplification of high-energy single-cycle laser pulses"). This achievement...
Most massive stellar black hole in our galaxy found
Apr 16, 2024 (Nanowerk News) Astronomers have identified the most massive stellar black hole yet discovered in the Milky Way galaxy. This black hole was spotted in data from the European Space Agency’s Gaia mission because it imposes an odd ‘wobbling’ motion on the companion star orbiting it. Data from...
Charge travels like light in bilayer graphene
Apr 16, 2024 (Nanowerk News) An international research team led by the University of Göttingen has demonstrated experimentally that electrons in naturally occurring double-layer graphene move like particles without any mass, in the same way that light travels. Furthermore, they have shown that the current can be “switched” on and...
