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 ...

A mild way to upcycle plastics used in bottles into fuel and other high-value products

29-Jan-2021

Plastic is ubiquitous in people's lives. Yet, when plastic-containing items have fulfilled their missions, only a small amount is recycled into new products, which are often of lower quality compared to the original material. And, transforming this waste into high-value chemicals requires ...

Superheroes, foods and apps bring a modern twist to the periodic table

Introducing Students to the Periodic Table Using a Descriptive Approach of Superheroes, Meats, and Fruits and Nuts

19-Jan-2021

Many students, especially non-science majors, dread chemistry. The first lesson in an introductory chemistry course typically deals with how to interpret the periodic table of elements, but its complexity can be overwhelming to students with little or no previous exposure. Now, researchers ...

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 ...

Gold- and bronze-like paints that don't contain metal

Researchers have developed organic-only dyes that can form films resembling gold or bronze, without the need for metals

19-Oct-2020

Lustrous metallic paints are used to enhance the beauty of many products, such as home decorations, cars and artwork. But most of these pigments owe their sheen to flakes of aluminum, copper, zinc or other metals, which have drawbacks. Now, researchers reporting in ACS Omega have developed ...

Levitating droplets allows to perform 'touchless' chemical reactions

Contact-free experiments without containers or handling that might affect the outcome

26-Jun-2020

Levitation has long been a staple of magic tricks and movies. But in the lab, it's no trick. Scientists can levitate droplets of liquid, though mixing them and observing the reactions has been challenging. The pay-off, however, could be big as it would allow researchers to conduct contact-free ...
