Highly emissive Sb3+-doped 0D cesium indium chloride nanocrystals with switchable photoluminescence
All-inorganic lead-free luminescent metal halide nanocrystals (NCs) are very important in optoelectronics, but their applications are limited by the low photoluminescence (PL) efficiency. It is an effective approach via ns2-metal ions doping for tailoring the optical properties of metal halide NCs and expanding their applications.
Quasi-symmetry in CoSi reveals new type of topological material
Ever since the discovery of the quantum Hall effect (Nobel Prize 1985), symmetry has been the guiding principle in the search for topological materials. Now an international team of researchers from Germany, Switzerland, and the U.S. has introduced an alternative guiding principle, "quasi-symmetry," which leads to the discovery of a new type of topological material with great potential for...
Discovery of high-speed moving plasma turbulence that outpaces the movement of heat
In order to achieve a fusion power plant, it is necessary to stably confine a plasma of more than 100 million degrees Celsius in a magnetic field and maintain it for a long time. A research group led by Assistant Professor Naoki Kenmochi, Professor Katsumi Ida, and Associate Professor Tokihiko Tokuzawa of the National Institute for Fusion Science (NIFS), National Institutes of Natural Sciences...
COVID has killed 5,600 Australians this year and the pandemic isn't over. Ethics can shape our response
It's difficult to ask, but how many fatalities should Australia accept from COVID in 2022?
Thermalization and information scrambling in a superconducting quantum processor
In recent years, physicists have carried out extensive studies focusing on quantum technology and quantum many-body systems. Two out-of-equilibrium dynamical processes that have attracted particular attention in this field are quantum thermalization and information scrambling.
Uncovering hidden cultures in workplaces can help make businesses more inclusive
Companies should introduce ways of uncovering informal hidden cultures to create more inclusive workplaces, a social mobility expert has told parliamentarians.
Blurring the boundary between Floquet matter and metamaterials
Metamaterials—artificial media with tailored subwavelength structures—have now encompassed a broad range of novel properties that are unavailable in nature. This field of research has stretched across different wave platforms, leading to the discovery and demonstration of a wealth of exotic wave phenomena. Most recently, metamaterial concepts have been extended to the temporal domain, paving...
How fast-growing algae could enhance growth of food crops
A new study provides a framework to boost crop growth by incorporating a strategy adopted from a fast-growing species of green algae. The algae, known as Chlamydomonas reinhardtii, contain an organelle called the pyrenoid that speeds up the conversion of carbon, which the algae absorb from the air, into a form that the organisms can use for growth. In a study published May 19, 2022 in the journal...
What’s sending kids to hospitals with hepatitis—coronavirus, adenovirus, or both?
To guide treatment, researchers scramble for data on the cause of mystery liver disease
How Stockholm applied greening concepts and what we can learn from it
Based on an evaluation of over 500 academic articles, an international research team has traced the application of greening concepts in the context of Swedish planning and particularly in the Stockholm metropolitan region. The researchers, who include Professor Christian Albert's research lab Planning Metropolitan Landscapes at Ruhr-Universität Bochum (RUB), have drawn up recommendations for...
New study offers hope that conservation can help nature adapt to climate change
A new study published in Biological Conservation reviews a suite of published scientific research, providing evidence that conservation action can help species adapt to a changing climate.
Ghostly 'mirror world' might be cause of cosmic controversy
New research suggests an unseen "mirror world" of particles that interacts with our world only via gravity that might be the key to solving a major puzzle in cosmology today—the Hubble constant problem.
Boeing aims for new test launch of Starliner astronaut capsule
The aerospace company hopes its Starliner vehicle can finally prove its capabilities in orbit.
Extinction: Why scientists are freezing threatened species in 'biobanks'
Conservation scientists hope that preserving genetic material offers future insurance against extinction
Pharmacy in the sea: Dolphins ‘use coral as medicine for skin ailments’
New research suggests the cetaceans may be self-medicating for their skin ailments, adding to evidence of the medicinal properties of some corals and spongesWho doesn’t like a bath scrub? Dolphins definitely do: they are known for being clever, playful, tactile animals, and they like to rub against rough surfaces, nap in coral beds and soak on sponges like guests at an underwater spa.However,...
These dolphins might be self-medicating
Animals rub against antibacterial corals and sponges, possibly to ward off skin infections
Broadening the scope of epoxide ring opening reactions with zirconocene
- ScienceDaily
- 22/5/19 16:38
Epoxide, a cyclic ether, can be used to obtain important alcohols, pharmaceuticals, agrochemicals, and functional polymers. This transformation is facilitated by the reductive ring opening of epoxide. Traditionally, the reaction has been catalyzed using titanocene. However, in this case, the products are predominantly obtained via more stable radicals. Now, chemists turn the tables and broaden the...

Atmospheric researchers have discovered a mechanism that allows nuclei for ice clouds to form and rapidly grow in the upper troposphere. Although the conditions for nucleus formation are only fulfilled in the Asian monsoon region, the mechanism is expected to have an impact on ice cloud formation across large parts of the Northern Hemisphere.
