Halogen bonding for selective electrochemical separation, path to sustainable chemical processing demonstrated      (via sciencedaily.com)     Original source 

A team has reported the first demonstration of selective electrochemical separation driven by halogen bonding. This was achieved by engineering a polymer that modulates the charge density on a halogen atom when electricity is applied. The polymer then attracts only certain targets -- such as halides, oxyanions, and even organic molecules -- from organic solutions, a feature that has important implications for pharmaceuticals and chemical synthesis processes.

How mortal filaments' self-assemble and maintain order: Align or die      (via sciencedaily.com)     Original source 

A previously unknown mechanism of active matter self-organization essential for bacterial cell division follows the motto 'dying to align': Misaligned filaments 'die' spontaneously to form a ring structure at the center of the dividing cell. The work could find applications in developing synthetic self-healing materials.

Treating radiation wounds with aspirin hydrogels      (via sciencedaily.com)     Original source 

Radiation is a powerful tool for treating cancer, but prolonged exposure can damage the skin. Radiation-induced skin injuries are painful and increase a person's chances of infection and long-term inflammation. Now, researchers report an aspirin-containing hydrogel that mimics the nutrient-rich fluid between cells and accelerates healing of skin damaged by radiation in animals. With further development, the new salve could provide effective and rapid wound healing for humans.

Increasing solid-state electrolyte conductivity and stability using helical structure      (via sciencedaily.com)     Original source 

Solid-state electrolytes have been explored for decades for use in energy storage systems and in the pursuit of solid-state batteries. These materials are safer alternatives to the traditional liquid electrolyte -- a solution that allows ions to move within the cell -- used in batteries today. However, new concepts are needed to push the performance of current solid polymer electrolytes to be viable for next generation materials.

How do butterflies stick to branches during metamorphosis?      (via sciencedaily.com)     Original source 

Most of us learned about butterfly metamorphosis as a kid -- a wriggly caterpillar molts its skin to form a tough chrysalis and emerges as a beautiful butterfly. But how exactly do chrysalises stay anchored as the butterfly brews within? Research shows that, despite their silks being weak and thin on their own, caterpillars can expertly spin them into chrysalis support structures resembling hook-and-loop fasteners and multi-strand safety tethers.

3D laser printing with bioinks from microalgae      (via sciencedaily.com)     Original source 

Microalgae such as the diatom Odontella aurita and the green alga Tetraselmis striata are especially suitable as 'biofactories' for the production of sustainable materials for 3D laser printing due to their high content in lipids and photoactive pigments. An international research team has succeeded for the first time in manufacturing inks for printing complex biocompatible 3D microstructures from the raw materials extracted from the microalgae.

New technology uses light to engrave erasable 3D images      (via sciencedaily.com)     Original source 

Researchers invented a technique that uses a specialized light projector and a photosensitive chemical additive to imprint two- and three-dimensional images inside any polymer. The light-based engraving remains in the polymer until heat or light are applied, which erases the image and makes it ready to use again. The technology is intended for any situation where having detailed, precise visual data in a compact and easily customizable format could be critical, such as planning surgeries and developing architectural designs.

Glimpse into the nanoworld: Microscope reveals tiniest cell processes      (via sciencedaily.com)     Original source 

What does the inside of a cell really look like? In the past, standard microscopes were limited in how well they could answer this question. Now, researchers have succeeded in developing a microscope with resolutions better than five nanometers (five billionths of a meter). This is roughly equivalent to the width of a hair split into 10,000 strands.
