The study is an example of serendipity in research

27-Jun-2022

The migration of carbon atoms on the surface of the nanomaterial graphene was recently measured for the first time. Although the atoms move too swiftly to be directly observed with an electron microscope, their effect on the stability of the material can now be determined indirectly while the ...

International team shows that the first biologically relevant compounds could have originated on Earth's surface

14-Jun-2022

The chemical precursors of present-day biomolecules could have formed not only in the deep sea at hydrothermal vents, but also in warm ponds on the Earth's surface. The chemical reactions that may have occurred in this “primordial soup” have now been reproduced in experiments by an international ...

A lithium-ion battery made with a bumpy carbon-based anode material maintained its rechargeable storage capacity in extreme cold

13-Jun-2022

When temperatures fall below freezing, cellphones need to be recharged frequently, and electric cars have shorter driving ranges. This is because their lithium-ion batteries’ anodes get sluggish, holding less charge and draining energy quickly. To improve electrical performance in the extreme ...

Scientists have successfully synthesized graphyne, which has been theorized for decades but never successfully produced

25-May-2022

For over a decade, scientists have attempted to synthesize a new form of carbon called graphyne with limited success. That endeavor is now at an end, though, thanks to new research from the University of Colorado Boulder. Graphyne has long been of interest to scientists because of its ...

Precise way to make nanodiamonds

25-Mar-2022

Diamonds aren’t just glittery, sparkly gems for jewelry. The smallest ones, only a few nanometers wide, are also crucial for drug delivery, sensors and quantum computer processors. Producing diamond nanoparticles that are consistently sized is important to the success of these technologies. Now, ...

“We could utilize two industrial waste products - ones that have historically been difficult to dispose of - and applied them to produce green hydrogen”

11-Feb-2022

Sea pineapples, an edible ascidian, are a delicacy in Japan. The Tohoku region is famed for its sea pineapple production - known as hoya in Japanese. Now, a research group has established a new use for the scores of sea pineapple shells that get discarded every year. Led by professor Hiroshi ...
