Passivation Layer in Lithium-Ion Batteries Explained

KIT researchers characterized chemical processes at the electrodes of lithium-ion batteries. In our daily lives, lithium-ion batteries have become indispensable. They function only because of a passivation layer that forms during their initial cycle. As researchers at Karlsruhe Institute of Technology (KIT) found out via simulations, this solid electrolyte interphase develops not directly at the electrode but aggregates in the solution. The scientists report on their study in the Advanced Energy Materials journal (DOI: 10.1002/aenm.202203966). Their findings allow the optimization of the performance…

X-Rays Uncover New Insights Into Nickel-Based Superconductors

Findings show similarities to and differences from cuprate superconductors, including more complex electronic structure. Scientists at the U.S. Department of Energy’s (DOE) Brookhaven National Laboratory have discovered new details about the electrons in a nickel-based family of superconducting materials. The research, described in two papers published in Physical Review X, reveals that these nickel-based materials have certain similarities with—and key differences from—copper-based superconductors. Comparing the two kinds of “high-temperature” superconductors may help scientists zero in on key features essential for these…

New driver for shapes of small quark-gluon plasma drops?

Results point to importance of internal structure of nucleons—and need for new measurements to disentangle other contributions. New measurements of how particles flow from collisions of different types of particles at the Relativistic Heavy Ion Collider (RHIC) have provided new insights into the origin of the shape of hot specks of matter generated in these collisions. The results may lead to a deeper understanding of the properties and dynamics of this form of matter, known as a quark-gluon plasma (QGP). QGP is…

Global Warming Drives Longer, Deadlier Wildfire Seasons

Increasing overlap of fire weather between Australia and North America complicates international firefighting efforts Climate change is increasing the risk of wildfires in many regions of the world. This is due partly to specific weather conditions – known as fire weather – that facilitate the spread of wildfires. Researchers from the Helmholtz Centre for Environmental Research (UFZ) and Australian colleagues have found that fire weather seasons are increasingly overlapping between eastern Australia and western North America. The research team examined…

Gold Ion Collisions Reveal Insights Into Critical Point Fluctuations

Analysis of lightweight nuclei emerging from gold ion collisions offers insight into primordial matter phase changes. Physicists analyzing data from gold ion smashups at the Relativistic Heavy Ion Collider (RHIC), a U.S. Department of Energy (DOE) Office of Science user facility for nuclear physics research at DOE’s Brookhaven National Laboratory, are searching for evidence that nails down a so-called critical point in the way nuclear matter changes from one phase to another. New findings from members of RHIC’s STAR Collaboration published in Physical…

New Seafloor Data Collector Installed at Boknis Eck Station

New measuring node was placed off Boknis Eck today. One of the oldest marine time series stations in the world is located in Eckernförde Bay, just under two kilometres off the coast: Boknis Eck. Since 1957, data on the state of the Baltic Sea have been collected regularly from a ship and, since 2016, also from an underwater observatory on the seafloor. After the device disappeared in 2019, the GEOMAR Helmholtz Centre for Ocean Research Kiel today launched a new,…

SPECULOOS Finds Potentially Habitable Super-Earths in Space

An international team of scientists, led by Laetitia Delrez, astrophysicist at the University of Liège (Belgium), has just announced the discovery of two ‘super-Earth’ type planets orbiting LP 890-9.  Also known as TOI-4306 or SPECULOOS-2, this small, cool star located about 100 light-years from our Earth is the second coolest star around which planets have been detected, after the famous TRAPPIST-1. This important discovery is published in the journal Astronomy & Astrophysics. A first planet, LP 890-9b (or TOI-4306b), the…

"Anti" sites most likely to come up first during Internet searches on vaccination

Almost half of the first top 10 websites displayed by leading search engines on vaccination are emotive “anti” sites, finds a study in the Archives of Disease in Childhood. Many masquerade as official scientific sites, making it easier for users to be misinformed, say the authors.

The researchers keyed in the terms “vaccination” and “immunis(z)ation” into seven leading search engines: Google; Netscape; Altavista; GoTo; HotBot; Lycos; and Yahoo. They then used just the term “vaccination,” for

Frozen ’lake’ beneath Antarctica ideal to test sterile drilling techniques

UC Berkeley scientist urges drilling into frozen lake under ice near South Pole as prelude to drilling into subglacial lakes in Antarctica and into Mars polar caps

Measurements of the ice temperature far below the South Pole suggest that a so-called “lake” discovered at the base of the ice is most likely permafrost – a frozen mixture of dirt and ice – because the temperature is too low for liquid water.
Far from being a disappointment, says a University of California, Berkeley p
