A high-yielding 4-step process for converting a naturally occurring terpene, β-pinene, into a substituted ε-caprolactone, and ring-opening polymerisation and copolymerisation of this monomer.

Most current plastics are made from oil, which is unsustainable. However, scientists from the Centre for Sustainable Chemical Technologies (CSCT) at the University of Bath have developed a renewable plastic from a chemical called pinene found in pine needles. Pinene is the fragrant chemical from the terpene family that gives pine trees their distinctive “Christmas smell” and is a waste product from the paper industry.

The researchers hope the plastic could be used in a range of applications, including food packaging, plastic bags and even medical implants...

An international team with UNIST has engineered a new artificial leaf that can convert sunlight into fuel with groundbreaking efficiency. In the study, the research presented a hetero-type dual photoelectrodes, in which 2 photoanodes of different bandgaps are connected in parallel for extended light harvesting. Their new artificial leaf mimics the natural process of underwater photosynthesis of aquatic plants to split water into hydrogen and oxygen, which can be harvested for fuel.

This study is expected to contribute greatly to the reduction and treatment of carbon dioxide emissions in accordance with the recent Paris Agreement on climate c...

MIT scientists have found that extreme precipitation events in California should become more frequent as the Earth’s climate warms over this century. Credit: Massachusetts Institute of Technology

On Dec. 11, 2014, a freight train of a storm steamed through much of California, deluging the SF Area with 3 inches of rain in just 1 hour. The storm was fueled by what meteorologists refer to as the “Pineapple Express”—an atmospheric river of moisture that is whipped up over the Pacific’s tropical waters and swept north with the jet stream. By evening, record rainfall had set off mudslides, floods, and power outages across the state. The storm, which has been called California’s “storm of the decade,” is among the state’s most extreme precipitation events in recent history.

Now MIT scientists...

Crash Test Cameras

2017 edition of NASA Spinoffs. NASA innovations we use in our daily lives. Here are some of our favorite things we bet you didn’t know use space technology.
1.Crash Test Cameras: Parachutes are a key part of the landing system for many of our spacecraft, but before we send them into orbit — or beyond — we have to make sure that they’re going to work as designed. One important component of testing is a video that captures every millisecond as the chute opens, to see if it’s working and if not, what went wrong. Integrated Design Tools built a camera for us that could do just that: rugged and compact, it can film up to 1,000 frames/s and back up all that data almost as fast...
