Researchers measure the breakup of a single chemical bond

“It's an incredible image - being able to actually see a single small molecule on a surface with another one bonded to it is amazing”

06-Oct-2021

The team used a high-resolution atomic force microscope (AFM) operating in a controlled environment at Princeton’s Imaging and Analysis Center. The AFM probe, whose tip ends in a single copper atom, was moved gradually closer to the iron-carbon bond until it was ruptured. The researchers measured ...

New route to chemically recyclable plastics

"This is about understanding really cool chemistry and trying to do something good with it"

27-Jan-2021

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 the discovery of a new polybutadiene molecule - from a material known for ...

Modern alchemists are making chemistry greener

18-Jun-2018

Ancient alchemists tried to turn lead and other common metals into gold and platinum. Modern chemists in Paul Chirik's lab at Princeton are transforming reactions that have depended on environmentally unfriendly precious metals, finding cheaper and greener alternatives to replace platinum, ...

Coffee physics

15-Dec-2017

For anyone who has marveled at the richly colored layers in a cafe latte, you're not alone. Princeton researchers, likewise intrigued, have now revealed how this tiered structure develops when espresso is poured into hot milk. "The structure formation in a latte is surprising because it evolves ...

Breakthrough could launch organic electronics beyond cell phone screens

21-Nov-2017

A discovery by an international team of researchers from Princeton University, the Georgia Institute of Technology and Humboldt University in Berlin points the way to more widespread use of an advanced technology generally known as organic electronics. The research focuses on organic ...

Studies of 'amorphous ice' reveal hidden order in glass

05-Oct-2017

The waves at the bottom of old window panes are a reminder that solid glass behaves like a very slow-moving liquid. Now a new study challenges the notion that the atomic structure of glass is indistinguishable from that of a liquid ­- at least for a certain kind of glass called "amorphous ice" ...

US nuclear regulators greatly underestimate potential for nuclear disaster

29-May-2017

The U.S. Nuclear Regulatory Commission (NRC) relied on faulty analysis to justify its refusal to adopt a critical measure for protecting Americans from the occurrence of a catastrophic nuclear-waste fire at any one of dozens of reactor sites around the country, according to an article in the May ...

Artificial topological matter opens new research directions

06-Apr-2017

An international team of researchers have created a new structure that allows the tuning of topological properties in such a way as to turn on or off these unique behaviors. The structure could open up possibilities for new explorations into the properties of topological states of matter. "This ...

Researchers create 'time crystals' envisioned by Princeton scientists

10-Mar-2017

Time crystals may sound like something from science fiction, having more to do with time travel or Dr. Who. These strange materials — in which atoms and molecules are arranged across space and time — are in fact quite real, and are opening up entirely new ways to think about the nature of matter. ...

Lead dressed like gold

02-Mar-2017

Since the Middle Ages, alchemists have sought to transmute elements, the most famous example being the long quest to turn lead into gold. Transmutation has been realized in modern times, but on a minute scale using a massive particle accelerator. Now, theorists at Princeton University have ...
