Phys.org / Mechanical recycling contamination risks the circular plastics economy, but quality control analytics can help
A study from the University of Manchester into the effects of polymer cross-contamination on the outcome of mechanically recycling plastics has found that the presence of contaminants radically alters degradation mechanisms.
Tech Xplore / New strategy for designing ultra-fast charging batteries could prevent hazardous lithium plating
The rapid progress in electric vehicles and high-power electronics has increased the demand for ultra-fast-charging lithium-ion (Li-ion) batteries. However, during fast charging, current Li-ion rechargeable batteries suffer ...
Phys.org / Indigenous territory maintains ecological stability amid agricultural expansion in the Brazilian savanna
"An island of biodiversity in a sea of monoculture": This is how a recent study characterized the Pimentel Barbosa Indigenous Territory (TIPB), located in the northeastern part of Mato Grosso state in Brazil's Central-West ...
Medical Xpress / Rat study finds early secondhand smoke exposure can alter tooth enamel mineralization
Exposure to secondhand cigarette smoke during the first days of life can cause changes in tooth enamel mineralization without causing visible changes to the teeth. This was demonstrated in an animal model study conducted ...
Phys.org / Photonic time crystals unlock ultrafast control of light in the terahertz range
An international team of researchers from École Polytechnique, Collège de France and Helmholtz-Zentrum Dresden-Rossendorf (HZDR) has achieved a world first: the experimental realization of an all-optical photonic time crystal ...
Phys.org / Scientists have found a new way molecules can cooperate at room temperature
What if glowing molecules could synchronize, much like fireflies flashing in unison? Researchers have discovered that molecules confined within tiny gold nanostructures can behave collectively, coordinating their interactions ...
Phys.org / Electrically controlled magnetic switching shows promise for next-gen cryogenic devices
Researchers at the Indian Institute of Science (IISc) have demonstrated a new way of switching a material between two fundamentally different magnetic states using an electric current. The discovery could pave the way for ...
Phys.org / Volcanic eruptions in Pacific Ring of Fire may have cooled Earth for centuries
For around 12,000 years, the Earth has been in the Holocene epoch, a warmer period following a glacial period. During this epoch, however, there have been around 22 abrupt cold phases, each lasting up to several centuries ...
Tech Xplore / Hidden battery flaw may shorten EV lifespans
As the need for sustainable electric vehicles grows, cobalt-free, high-nickel cathode batteries (such as manganese-coated nickel-core batteries) have emerged as one of the most promising technologies. These batteries increase ...
Phys.org / New research shows how 'hot electrons' can reshape metals in billionths of a second
Researchers at The University of Manchester have revealed how intense electronic excitation can trigger rapid structural changes in metals—without heating the atomic lattice—offering new insight into ultrafast materials behavior.
Tech Xplore / Can AI's power problem become a clean-energy opportunity?
Artificial intelligence has triggered a new gold rush. This time, companies are competing not for land or minerals, but for access to electricity.
Phys.org / Christmas in July: Engineers capture gigapixel 3D video of snowflakes
For the first time, researchers can witness nanometer-scale thickness changes across a melting snowflake with a compact, lensless chip that captures gigapixel video at 30 frames per second across centimeter-scale fields.
