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.

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.
