The substitution of petrochemical materials with those obtained from renewable raw materials is an important step towards increasing sustainability. In just two years of intensive and open collaboration between Empa and the Datwyler Schweiz AG as part of an Innosuisse project, a process was successfully developed that brought together the worlds of cellulose and rubbers.
Electrochemical reduction can convert carbon dioxide into multicarbon products for use as a raw material in chemicals and fuels. In this research, scientists improved this conversion process by using a tandem catalyst electrode. The electrode includes a silver or iron-nitrogen-carbon-based catalyst to convert carbon dioxide into carbon monoxide and incorporates a second segment that contains a copper catalyst to convert carbon monoxide into multicarbon products. Relative to prior methods, the developed approach more selectively converts carbon dioxide into desired compounds.
Scientists have long been fascinated with the origin of life on Earth, namely the transition from simple pre-biotic organic molecules to living cell systems.
Researchers have discovered that an 80 year old historic World War II shipwreck is still influencing the microbiology and geochemistry of the ocean floor where it rests.
KIMM announced that it has developed a hydrogen co-firing combustor for gas turbines used in power generation.
Researchers at Binghamton University, State University of New York are working to understand the molecular composition of tattoo inks to provide knowledge to artists and consumers.
Often referred to as smart materials, temperature-responsive or thermoresponsive polymers are gaining attention for their ability to respond to external temperature changes, allowing for an extensive range of applications.
Scientists use high-energy protons to create isotopes for cancer treatment. In space, such protons pose a risk to astronauts and spacecraft. To learn more about both the risks from these protons and about methods of using these protons to produce medical isotopes, scientists measured the cross sections (probabilities) for high-energy proton reactions used to produce radiopharmaceuticals. The research helps to optimize the quantity and purity of medical isotopes and improve the design of spacecraft shielding.
Scientists working on a solution for plastic waste have developed a two-step chemical and biological process to break down and upcycle mixed plastics into valuable bioproducts.
Adaptable and versatile, molecular qubits hold promise for numerous quantum applications. By altering the qubit's host environment, a team supported by the Q-NEXT quantum center has extended the length of time these qubits can maintain information.
The plastic, made from a chemical found in the extract of a vanilla bean, degrades when exposed to a specific wavelength of light
John C. Gordon has been named Chemistry Division Chair at the U.S. Department of Energy’s (DOE) Brookhaven National Laboratory, effective Sept. 12, 2022.
Researchers reporting in ACS Sensors have designed a food-grade device from edible materials that lets you know if food has been thawed and refrozen . The proof-of-concept sensor provides a color readout when it’s warmed above a specific temperature, which is tunable from -58 F to 32 F.
Ramping up renewable energy products will require a range of critical metals. One of these elements, tellurium, is gaining in popularity for use in photovoltaics, or solar panels. As global demand for solar panels continues to increase, so is the need for critical metals like tellurium.
Scientists at Brookhaven National Laboratory and collaborators at Cold Spring Harbor Laboratory have engineered duckweed to produce high yields of oil. The team added genes to one of nature's fastest growing aquatic plants to "push" the synthesis of fatty acids, "pull" those fatty acids into oils, and "protect" the oil from degradation.
Textile engineers have developed a fabric woven out of ultra-fine nano-threads made in part of phase-change materials and other advanced substances that combine to produce a fabric that can respond to changing temperatures to heat up and cool down its wearer depending on need.
Understanding the fundamentals of these emerging technologies will help design improved systems for chemical recycling and upcycling of waste plastics.
The scientific expedition to the Nord Stream leak from the University of Gothenburg has arrived back home.
Story tips from Oak Ridge National Laboratory including reducing molten salt’s corrosive effect, VERIFI-ing and tracking carbon’s big footprint, moss genome study identifies two new species and ultrasound for battery health.
