Supercomputer simulation reveals 2-D glass can go infinitely soft

16-Dec-2016

Scientists in Japan have revealed that if a glassy solid possesses a planar (sheet-like) structure, it can exhibit enhanced thermal vibration motion due to the same mechanism known for the planar crystals (two-dimensional crystals), by using large-scale simulations on supercomputers. "Imagine if ...

A new form of light

Scientists have discovered a method to create fluorescent light that may have promising applications

06-Oct-2016

Glow-in-the-dark stickers, weird deep-sea fish, LED lightbulbs -- all have forms of luminescence. In other words, instead of just reflecting light, they make their own. Now a team of scientists from the University of Vermont and Dartmouth College have discovered a new way that some molecules can ...

Closing in on the elusive rotational-vibrational CH5+ spectra

25-May-2016

Protonated methane, a.k.a. CH5+, is a highly unusual molecule that scientists and astronomers suspect may be found within the interstellar medium where stars and planets are formed. To identify molecules on Earth or in outer space, scientists typically record the spectrum of light absorbed -- ...

Stochastic resonance, chaos transfer shown in an optomechanical microresonator

11-May-2016

Researchers in the School of Engineering & Applied Science at Washington University in St. Louis have discovered a novel route to encode chaos on light in an optomechanical microresonator system. An optomechanical microresonator system combines optics and mechanics in a very small area to study ...

New ways to construct contactless magnetic gears

18-Feb-2016

The new milk frother you are using to prepare your cappuccino is likely using magnetic gears. Magnetic gears transmit rotary motion like mechanical gears but instead of teeth they use magnetic attraction and repulsion between rotating magnets. Dr Johannes Schoenke, a postdoctoral scholar at the ...

Ringing in a new way to measure and modulate trapped light

24-Dec-2015

Researchers working at the National Institute of Standards and Technology (NIST) have developed a novel way to noninvasively measure and map how and where trapped light vibrates within microscale optical resonators. The new technique not only makes for more accurate measurements but also allows ...

Researcher uses vibrations to identify materials' composition

Hybrid photonic-nanomechanical force microscopy (HPFM) brings greater spatial resolution

12-Aug-2015

A researcher at the University of Central Florida has developed a new method for identifying materials' unique chemical "fingerprints" and mapping their chemical properties at a much higher spatial resolution than ever before. It's a discovery that could have promising implications for fields as ...

Industrial pump inspired by flapping bird wings

New ratcheting pump uses vibrations instead of traditional rotor to transport fluids

05-Feb-2015

Birds are unwitting masters of fluid dynamics - they manipulate airflow each time they flap their wings, pushing air in one direction and moving themselves in another. Two New York University researchers have taken inspiration from avian locomotion strategies and created a pump that moves fluid ...

Vibration energy the secret to self-powered electronics

24-Feb-2014

A multi-university team of engineers has developed what could be a promising solution for charging smartphone batteries on the go — without the need for an electrical cord. Incorporated directly into a cell phone housing, the team's nanogenerator could harvest and convert vibration energy from a ...

Musical molecules

Nanofibers align to the sound of Beethoven and Mozart

13-Jan-2014

Humans create and perform music for a variety of purposes such as aesthetic pleasure, healing, religion, and ceremony. Accordingly, a scientific question arises: Can molecules or molecular assemblies interact physically with the sound vibrations of music? In the journal ChemPlusChem, Japanese ...
