Researchers uncover new water monitoring technique
New method simultaneously monitors clumps and the mixing intensity in a single step
03-Mar-2023
Water is a vital resource, and clean water is a necessity. Texas A&M University researchers have developed a new technique to monitor one of the key processes of purifying water in real time. Raw water contains microscopic pathogens that are too small to remove during water and wastewater ...
Machine learning model speeds up assessing catalysts for decarbonization technology from months to milliseconds
Scientists create computational model for identifying low-cost catalysts that convert biomass into fuels and useful chemicals with low carbon footprint
02-Mar-2023
Next time you drive past farms or prairies and ponds on a rural road, look around. They are a rich source of biomass. That includes corn, soybeans, sugar cane, switchgrass, algae and other plant matter. These carbon-rich materials can be converted to liquid fuels and chemicals with many possible ...
Are your strawberries bland? Pesticides could be to blame
How fungicides can ruin the sweetness and nutritional value of strawberries
01-Mar-2023
Have you ever bitten into a plump, red strawberry, only to find it bland and watery? Certain pesticides might be responsible. A team reporting in ACS’ Journal of Agricultural and Food Chemistry has found that two common strawberry fungicides can impact cellular mechanisms, creating berries with ...
A newly developed catalyst makes single-use plastics easier to upcycle, recycle, and biodegrade
Revolutionary breakthrough: The catalyst transforms motor oil, plastic and natural gas into sustainable materials
28-Feb-2023
Researchers created a new catalyst that transforms hydrocarbons into chemicals and materials that are higher value, easier to recycle, and biodegrade in the environment. This catalyst transforms materials such as motor oil, plastics in single-use grocery bags, water or milk bottles, and their ...
On the road to better solid-state batteries
A Berkeley Lab-led team designs next-gen batteries at the atomic level
28-Feb-2023
A team from Lawrence Berkeley National Laboratory (Berkeley Lab) and Florida State University has designed a new blueprint for solid-state batteries that are less dependent on specific chemical elements, particularly critical metals that are challenging to source due to supply chain issues. Their ...
Researchers use light to convert abundant lignin into plastic that can be continually recycled
New process could advance a waste-free system of polymer manufacture and re-use
24-Feb-2023
Lignin is arguably the most abundant component of biomass that most people have never heard of. That may be about to change. Many people are familiar with its biochemical cousin cellulose, a byproduct of paper and wood milling. But the same processes produce 50 million tons of lignin annually, ...
Carrots: Good for your eyes … and for degradable polymers
Researchers have incorporated a compound derived from β-carotene into a polymer that’s fully degradable
23-Feb-2023
Carrots come in a rainbow of bright colors — red, orange, yellow and purplish black — because of compounds called carotenoids. They help support eye health by reacting with potentially harmful UV light. Interestingly, the molecular structures of carotenoids, such as β-carotene, are similar to the ...
Perovskites, a ‘dirt cheap’ alternative to silicon, just got a lot more efficient
Researchers use substrates of metal and dielectrics to boost the light conversion efficiency of perovskites by 250 percent
22-Feb-2023
Silicon, the standard semiconducting material used in a host of applications—computer central processing units (CPUs), semiconductor chips, detectors, and solar cells—is an abundant, naturally occurring material. However, it is expensive to mine and to purify. Perovskites—a family of materials ...
Next generation solar fuels: How a record-breaking copper catalyst converts CO₂ into liquid fuels
Researchers have made real-time movies of copper nanoparticles as they evolve to convert carbon dioxide and water into renewable fuels and chemicals
21-Feb-2023
Since the 1970s, scientists have known that copper has a special ability to transform carbon dioxide into valuable chemicals and fuels. But for many years, scientists have struggled to understand how this common metal works as an electrocatalyst, a mechanism that uses energy from electrons to ...
Waters acquires Wyatt Technology for $1.36 billion
Accelerates next phase of Waters' growth and value creation strategy
17-Feb-2023
Waters Corporation announced it has entered into an agreement to acquire Wyatt Technology, a pioneer in innovative light scattering and field-flow fractionation instruments, software, accessories, and services, for $1.36 billion in cash, subject to certain adjustments. The transaction is expected ...
