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.

Chemists develop new sustainable reaction for creating unique molecular building blocks      (via sciencedaily.com)     Original source 

Polymers can be thought of like trains: Just as a train is composed of multiple cars, polymers are made up of multiple monomers, and the couplings between the train cars are similar to the chemical bonds that link monomers together. While polymers have myriad applications -- from drug delivery to construction materials -- their structures and functions are restricted by the chemically similar monomer building blocks they're composed of. Now, chemists have developed a new reaction to create unique monomers in a controlled way. This reaction, which uses nickel as a catalyst, ultimately enables scientists to create polymers with unique and modifiable properties for drug delivery, energy storage, microelectronics and more.

Breakthrough in molecular control: New bioinspired double helix with switchable chirality      (via sciencedaily.com)     Original source 

The control of artificial double-helical structures, which are essential for the development of high-order molecular systems, remains difficult. In a new study, researchers have developed novel double-helical monometallofoldamers that exhibit controllable helicity inversion and chiral information transfer, in response to external stimuli. These monometallofoldamers can lead to novel artificial supramolecular systems for molecular information transmission, amplification, replication, and other exciting applications in various fields of technology.

Concept for efficiency-enhanced noble-metal catalysts      (via sciencedaily.com)     Original source 

The production of more than 90 percent of all chemical products we use in our everyday lives relies on catalysts. Catalysts speed up chemical reactions, can reduce the energy required for these processes, and in some cases, reactions would not be possible at all without catalysts. Researchers developed a concept that increases the stability of noble-metal catalysts and requires less noble metal for their production.

Marine biologists are providing a glimpse into coral 'bleaching' responses to stress, using imaging technology to pinpoint coral survival rates following multiple bleaching events off the island of Maui. Using a time series of coral reef 3D models from Maui, the researchers tracked the bleaching response of 1,832 coral colonies from 2014 to 2021. The seven-year data set provided detailed imagery of the reefs year-by-year, allowing the team to identify patterns of coral growth and survivorship through sequential bleaching events that occurred in 2015 and 2019.
