Molecular simulations, supercomputing lead to energy-saving biomaterials breakthrough
Posted by Shubham Ghosh Roy in categories: 3D printing, economics, energy, supercomputing, sustainability, transportation
A team led by scientists at the Department of Energy’s Oak Ridge National Laboratory identified and successfully demonstrated a new method to process a plant-based material called nanocellulose that reduced energy needs by a whopping 21%. The approach was discovered using molecular simulations run on the lab’s supercomputers, followed by pilot testing and analysis.
The method, leveraging a solvent of sodium hydroxide and urea in water, can significantly lower the production cost of nanocellulosic fiber — a strong, lightweight biomaterial ideal as a composite for 3D-printing structures such as sustainable housing and vehicle assemblies. The findings support the development of a circular bioeconomy in which renewable, biodegradable materials replace petroleum-based resources, decarbonizing the economy and reducing waste.
Colleagues at ORNL, the University of Tennessee, Knoxville, and the University of Maine’s Process Development Center collaborated on the project that targets a more efficient method of producing a highly desirable material. Nanocellulose is a form of the natural polymer cellulose found in plant cell walls that is up to eight times stronger than steel.

Senegal among new members of China’s ILRS moon base project
Posted by Saúl Morales Rodriguéz in category: space
HELSINKI — Senegal’s space agency signed an agreement on cooperation on the International Lunar Research Station Thursday, swelling the ranks of the China-led project.
Maram Kaire, head of the Senegalese Space Study Agency (ASES) and Li Guoping, chief engineer of the China National Space Administration (CNSA) signed the agreement on cooperation in the International Lunar Research Station (ILRS) at the second international conference on deep space exploration (Tiandu) in Tunxi, Anhui province, Sept. 5.
The agreement came as Chinese President Xi Jinping held talks with Senegalese President Bassirou Diomaye Faye. The latter is visiting for the Beijing Summit of the Forum on China-Africa Cooperation (FOCAC) and a state visit.

Finger wrap uses sweat to provide health monitoring at your fingertips
Posted by Saúl Morales Rodriguéz in categories: biotech/medical, chemistry, engineering, health, wearables
A sweat-powered wearable has the potential to make continuous, personalized health monitoring as effortless as wearing a Band-Aid. Engineers at the University of California San Diego have developed an electronic finger wrap that monitors vital chemical levels—such as glucose, vitamins, and even drugs—present in the same fingertip sweat from which it derives its energy.
The advance was published Sept. 3 in Nature Electronics by the research group of Joseph Wang, a professor in the Aiiso Yufeng Li Family Department of Chemical and Nano Engineering at UC San Diego.
The device, which wraps snugly around the finger, draws power from an unlikely source—the fingertip’s sweat. Fingertips, despite their small size, are among the body’s most prolific sweat producers, each packed with over a thousand sweat glands. These glands can produce 100 to 1,000 times more sweat than most other areas of the body, even during rest.
