To make fluid flow in one direction down a pipe, it helps to be a shark

Researchers have discovered a new way to help liquid flow in only one direction, but without using the flaps that engines and our circulatory system rely upon to prevent fluid backup.

Drug delivery via textile fibers

Medical products such as ointments or syringes reach their limits when it comes to delivering medication locally – and above all in a controlled manner over a longer period of time. Empa researchers are therefore developing polymer fibers that can deliver active ingredients precisely over the long term. These “liquid core fibers” contain drugs inside and can be processed into medical textiles.

Modeling Polymers for Next-Generation Manufacturing and Sustainability

Polymers experience changing conditions during manufacturing, which can affect their final properties and performance. The way they react to manufacturing forces can be extremely complex and hard to measure. Researchers combined theory and modeling to characterize melted polymers under steady flow and revealed universal features that can inform the design of advanced materials for manufacturing.

How Scientists Are Accelerating Next-Gen Microelectronics

In a new Q&A, microelectronics expert and CHiPPS Director Ricardo Ruiz shares his perspective on keeping pace with Moore’s Law in the decades to come through a revolutionary technique called extreme ultraviolet lithography.

What can we do about all the plastic waste?

The Institute for the Cooperative Upcycling of Plastics (iCOUP) is helping to address the plastic waste accumulation problem by developing the science needed to turn used plastic into valuable materials.

New machine-learning simulations reduce energy need for mask fabrics, other materials

A new computational effort between Argonne and 3M promises to reduce energy consumption without sacrificing material quality in the production of nonwoven plastics, commonly used in surgical masks.

Print, Recycle, Repeat: Scientists Demonstrate a Biodegradable Printed Circuit

Scientists have developed a fully recyclable and biodegradable printed circuit. The advance could divert wearable devices and other flexible electronics from landfill, and mitigate the health and environmental hazards posed by heavy metal waste.

Closed-loop additive manufacturing fueled by upcycled plastic

Researchers at the Department of Energy’s Oak Ridge National Laboratory have developed an upcycling approach that adds value to discarded plastics for reuse in additive manufacturing, or 3D printing. The readily adoptable, scalable method introduces a closed-loop strategy that could globally reduce plastic waste and cut carbon emissions tied to plastic production.

Editors of MIT Technology Review name Argonne’s Jie Xu as a 2021 Innovator Under 35

The editors of MIT Technology Review have chosen Argonne’s Jie Xu as an Innovator Under 35 for 2021. She is one of only 35 innovators under the age of 35 named to this list. She is being recognized for her research on printable skin-like electronics.

Polymers in Meteorites Provide Clues to Early Solar System

Meteorites that do not experience high temperatures at any point in their existence provide a good record of complex chemistry present when or before our solar system was formed. So researchers have examined individual amino acids in these meteorites, many of which are not in present-day organisms. In Physics of Fluids, researchers show the existence of a systematic group of amino acid polymers across several members of the oldest meteorite class, the CV3 type.

8 Things Argonne is Doing to Save the Earth

Stepping into their superhero gear, Argonne scientists are using science and the world’s best technology to combat some of Earth’s toughest foes, from pollution to climate change.

Paper or Plastic? OU Chemical Engineers Work to Make Plastic Bags Recyclable and Compostable

Single-use plastic bags continue to pose a global environmental challenge, as their composition and form makes them difficult to recycle, and hundreds of years are required for them to degrade fully in the environment. While reusabable shopping bags offer an earth-friendly option, what if plastic bags could be recycled or placed in our composts?

Exploring Blended Materials Along Compositional Gradients

A new platform could accelerate the development of blended materials with desired properties.

New Science Behind Algae-based Flip-flops

UC San Diego researchers formulated polyurethane foams, made from algae oil, to meet commercial specifications for midsole shoes and the foot-bed of flip-flops. Their latest result, in a series of recent research publications, offers a complete solution to the plastics problem—at least for polyurethanes.

Battery Breakthrough Gives Boost to Electric Flight and Long-Range Electric Cars

Researchers at Berkeley Lab, in collaboration with Carnegie Mellon University, have developed a new battery material that could enable long-range electric vehicles that can drive for hundreds of miles on a single charge, and electric planes called eVTOLs for fast, environmentally friendly commutes.
