Growing extremely tiny, uniformly sized diamonds — without explosives

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, ...

Camels’ noses inspire a new humidity sensor

Device could reliably detect variations in humidity in settings that included industrial exhaust and the air surrounding human skin

21-Jan-2022

Camels have a renowned ability to survive on little water. They are also adept at finding something to drink in the vast desert, using noses that are exquisite moisture detectors. In a new study in ACS Nano, researchers describe a humidity sensor inspired by the structure and properties of ...

Biofuels from the brewery?

Separating beer waste into proteins for foods, and fiber for biofuels

07-Apr-2021

Home brewing enthusiasts and major manufacturers alike experience the same result of the beer-making process: mounds of leftover grain. Once all the flavor has been extracted from barley and other grains, what's left is a protein- and fiber-rich powder that is typically used in cattle feed or put ...

Double-duty catalyst generates hydrogen fuel while cleaning up wastewater

19-Mar-2021

Hydrogen is a pollution-free energy source when it's extracted from water using sunlight instead of fossil fuels. But current strategies for "splitting" or breaking apart water molecules with catalysts and light require the introduction of chemical additives to expedite the process. Now, ...

Termite gut microbes could aid biofuel production

Microbes can help break down lignin

22-Feb-2021

Wheat straw, the dried stalks left over from grain production, is a potential source of biofuels and commodity chemicals. But before straw can be converted to useful products by biorefineries, the polymers that make it up must be broken down into their building blocks. Now, researchers reporting ...

Luminescent wood could light up homes of the future

Luminescent and hydrophobic wood films as optical lighting materials

06-Nov-2020

The right indoor lighting can help set the mood, from a soft romantic glow to bright, stimulating colors. But some materials used for lighting, such as plastics, are not eco-friendly. Now, researchers reporting in ACS Nano have developed a bio-based, luminescent, water-resistant wood film that ...
