3D-printed material to replace ivory for restoration of artifacts
For centuries, ivory was often used to make art objects. But to protect elephant populations, the ivory trade was banned internationally in 1989. To restore ivory parts of old art objects, one must therefore resort to substitute materials—such as b.....»»
Researchers develop high-performance blue organic LEDs based on thermally activated delayed fluorescence material
Organic light-emitting diodes (OLEDs) have become a leading display technology. The luminescent material is a core component of OLEDs. Thermally activated delayed fluorescence (TADF) materials have emerged as promising emitters for achieving high-eff.....»»
Setting minimum targets for wildlife conservation excludes restoration and ecosystem management, researcher argues
Although the grizzly is featured prominently on the California state flag, the golden bear has been extinct in the wild since the 1920s......»»

Chemists Chase ‘Clean’ Ammonia to Replace Shipping Fuel
President Biden’s climate law is funding “green ammonia” projects in hopes of using the chemical to more cleanly power the grid, fuel cargo ships and make fertilizer.....»»
Researchers reveal a new mechanism of hyaluronic acid with a specific molecular weight to improve host inflammation
Previous studies on the function of glycosaminoglycans have primarily focused on improving host physiological indices. However, little attention has been paid to the material basis and mechanism of their mediated improvement of host health by gut mic.....»»
3D-MAT, a thermal protection material for the Artemis Generation
The 3-Dimensional Multifunctional Ablative Thermal Protection System (3D-MAT) is a thermal protection material developed as a critical component of Orion, NASA's newest spacecraft built for human deep space missions. It is able to maintain a high lev.....»»
Researchers create new type of composite material for shielding against neutron and gamma radiation
Recently, Dr. Huo Zhipeng and his student Lu Yidong from Hefei Institutes of Physical Science of Chinese Academy of Sciences have created a new type of composite material for shielding against neutron and gamma radiation. They used micron plate Sm2O3.....»»
Researchers develop framework for databasing properties of crystal defects
Point defects (e.g. missing, extra or swapped atoms) in crystalline materials often determine the actual electronic and optical response of a given material. For example, controlled substitutions in semiconductors like silicon are the backbone of mod.....»»
Sustainable, high-performance paper coating material could reduce microplastic pollution
Plastic pollution presents a global challenge that must be solved. In particular, packaging accounts for 30–50% of the total plastic consumption. While paper packaging is eco-friendly, it lacks crucial functionalities like moisture resistance and s.....»»
Packaged-meat labels that show freshness could replace use-by dates, reducing food waste
Patches that change color as raw meat freshness deteriorates in sealed refrigerated products could soon become a reality on supermarket shelves, making it easier for shoppers to know if it's still good to eat and reducing food waste......»»
Study indicates interstitial Cu reduces the defect density in matrix and suppresses the donor-like effect
Due to the capacity to directly and reversibly convert heat into electricity, thermoelectric (TE) material has potential applications in solid-state heat pumping and exhaust heat recuperation, thus attracting worldwide attention. Bi2Te3 stands out fo.....»»
New polystyrene recycling process could be world"s first to be both economical and energy-efficient
Engineers have modeled a new way to recycle polystyrene that could become the first viable way of making the material reusable. The chemical method identified to tackle hard-to-recycle packaging material, cutting landfill waste.....»»
New insights into the degradation dynamics of organic material in the seafloor
The long-term deposition of organic material in sediments on the ocean floor is a key process in the global carbon cycle. The question of whether, from a chemical perspective, the deposited material is more similar to marine algae or the microorganis.....»»
A metal-free organic framework for electrocatalytic production of ethylene from carbon dioxide
Use of the greenhouse gas CO2 as a chemical raw material would not only reduce emissions, but also the consumption of fossil feedstocks. A novel metal-free organic framework could make it possible to electrocatalytically produce ethylene, a primary c.....»»
Using wobbling stellar material, astronomers measure the spin of a supermassive black hole for the first time
Astronomers at MIT, NASA, and elsewhere have a new way to measure how fast a black hole spins, by using the wobbly aftermath from its stellar feasting......»»
Excavation reveals "major" ancient migration to Timor Island
The discovery of thousands of stone artifacts and animal bones in a deep cave in Timor Island has led archaeologists to reassess the route that early humans took to reach Australia......»»
How three tenacious reefs can help restore global oyster populations
Researchers at the University of Sydney have revealed how our oyster reefs can provide lessons on reef restoration projects. More than 85% of naturally occurring oyster reefs have been lost in recent decades due to disease, overharvesting, global war.....»»
Researchers test ways to remove "forever chemicals" from the environment and replace them in commercial goods
