New mechanism to cool buildings while saving energy      (via sciencedaily.com)     Original source 

The movement of radiant heat -- felt when a hot surface warms our bodies and homes -- between buildings and their surroundings at ground level makes buildings with less skyward-facing surfaces harder to cool. A research team has demonstrated a new passive cooling technology that coats walls and windows with materials that can better manage heat movement between buildings and their surroundings at ground level. Findings could reduce the reliance on air conditioning and provide a more environmentally friendly, low-cost and scalable option for low-income communities with limited or no access to cooling and heating systems.

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.

Detecting climate change using aerosols      (via sciencedaily.com)     Original source 

Researchers analyzed long-term aerosol satellite observation big data focusing on the Pacific Ocean downwind of China. Using a newly developed metric that considered aerosols as tracers, they detected altered atmospheric transport patterns associated with climate change. They observed that the distance of transboundary air pollution moving east from China had shortened. Thus, long-term satellite-based Earth observations are crucial for early climate change detection and accurate evaluation of this trend.
