Creating a 3-D-printed bioresorbable airway stent

Narrowing of the trachea or the main bronchi due to injury or illness can end very badly. If patients get too little air,oxygen, they risk suffocating and often need medical help as quickly as possible.

Researchers advance new route to chemically recyclable plastics

As the planet's burden of rubber and plastic trash rises unabated, scientists increasingly look to the promise of closed-loop recycling to reduce waste. A team of researchers at Princeton's Department of Chemistry announces ...

Ultraheavy precision polymers

An environmentally friendly and sustainable synthesis of 'heavyweight' polymers with very narrow molecular weight distributions is an important concept in modern polymer chemistry. Thanks to a new photoenzymatic process, ...

Scientists working on next-gen nanocars

Nanomechanics at Rice University and the University of Houston are getting ready to rev their engines for the second international Nanocar Race.

It takes a neutron beam to find a proton

Understanding the behavior of proteins and enzymes is key to unlocking the secrets of biological processes. The atomic structures of proteins are generally investigated using X-ray crystallography; however, the precise information ...
