The 1.5°C target is dead, but climate action needn't be

New Scientist Feed - Wed, 08/21/2024 - 11:00am
For the first time, climate scientists have explicitly said it will be impossible to limit peak warming to 1.5°C. Now our focus should be on taking action, not meaningless platitudes and slogans

Chalk-based coating creates a cooling fabric

Matter and energy from Science Daily Feed - Wed, 08/21/2024 - 9:44am
In the scorching heat of summer, anyone who spends time outside could benefit from a cooling fabric. While there are some textiles that reflect the sun's rays or wick heat away, current options require boutique fibers or complex manufacturing processes. But now, demonstrations of a durable chalk-based coating show it can cool the air underneath treated fabric by up to 8 degrees Fahrenheit.

First visualization of valence electrons reveals fundamental nature of chemical bonding

Matter and energy from Science Daily Feed - Wed, 08/21/2024 - 9:44am
The distribution of outermost shell electrons, known as valence electrons, of organic molecules was observed for the first time. As the interactions between atoms are governed by the valence electrons, the findings shine light on the fundamental nature of chemical bonds, with implications for pharmacy and chemical engineering.

Quality control: Neatly arranging crystal growth to make fine thin films

Matter and energy from Science Daily Feed - Wed, 08/21/2024 - 9:44am
Researchers have succeeded in forming metal-organic framework thin films on a substrate while controlling the growth direction of crystals so that they are arranged neatly without gaps. The resulting thin films of unprecedented high quality can be expected for use as optical sensors, optical elements, and transparent gas adsorption sheets.

More academic freedom leads to more innovation

Matter and energy from Science Daily Feed - Wed, 08/21/2024 - 9:43am
The innovative strength of a society depends on the level of academic freedom. An international team has now demonstrated this relationship. The researchers analyzed patent applications and patent citations in a sample from around 160 countries over the 1900--2015 period in relation to indicators used in the Academic Freedom Index. In view of the global decline in academic freedom over the past 10 years, the researchers predict a loss in innovative output.

Dormant capacity reserve in lithium-ion batteries detected

Matter and energy from Science Daily Feed - Wed, 08/21/2024 - 9:43am
Lithium iron phosphate is one of the most important materials for batteries in electric cars, stationary energy storage systems and tools. It has a long service life, is comparatively inexpensive and does not tend to spontaneously combust. Energy density is also making progress. However, experts are still puzzled as to why lithium iron phosphate batteries undercut their theoretical electricity storage capacity by up to 25 per cent in practice.

Engineered Bacteria make thermally stable plastics similar to polystyrene and PET

Matter and energy from Science Daily Feed - Wed, 08/21/2024 - 9:42am
Bioengineers around the world have been working to create plastic-producing microbes that could replace the petroleum-based plastics industry. Now, researchers have overcome a major hurdle: getting bacteria to produce polymers that contain ring-like structures, which make the plastics more rigid and thermally stable. Because these molecules are usually toxic to microorganisms, the researchers had to construct a novel metabolic pathway that would enable the E. coli bacteria to both produce and tolerate the accumulation of the polymer and the building blocks it is composed of. The resulting polymer is biodegradable and has physical properties that could lend it to biomedical applications such as drug delivery, though more research is needed.

New heaviest exotic antimatter nucleus

Matter and energy from Science Daily Feed - Wed, 08/21/2024 - 9:42am
Scientists studying the tracks of particles streaming from six billion collisions of atomic nuclei at the Relativistic Heavy Ion Collider (RHIC) -- an 'atom smasher' that recreates the conditions of the early universe -- have discovered a new kind of antimatter nucleus, the heaviest ever detected. Composed of four antimatter particles -- an antiproton, two antineutrons, and one antihyperon -- these exotic antinuclei are known as antihyperhydrogen-4.
