A new method to detect nucleation

27-Jul-2018

As a solution evaporates, the dissolved chemicals concentrate until they begin forming a crystal through a process called nucleation. Industries that use small crystals in pharmaceuticals, food and microelectronics are seeking to understanding this nucleation event. Scientists studying nucleation ...

Modelling how fracturing metallic glass releases energy at the atomic level

20-Jul-2018

Metallic glasses -- alloys lacking the crystalline structure normally found in metals -- are an exciting research target for tantalizing applications, including artificial joints and other medical implant devices. However, the difficulties associated with predicting how much energy these ...

New cost-effective instrument measures molecular dynamics on a picosecond timescale

19-Jul-2018

Studying the photochemistry, or chemical results of light, has shown that ultraviolet radiation can set off harmful chemical reactions in the human body and, alternatively, can provide "photo-protection" by dispersing extra energy. To better understand the dynamics of these photochemical ...

The culprit of some GaN defects could be nitrogen

04-Jul-2018

As silicon-based semiconductors reach their performance limits, gallium nitride (GaN) is becoming the next go-to material to advance light-emitting diode (LED) technologies, high-frequency transistors and photovoltaic devices. Holding GaN back, however, is its high numbers of defects. This ...

THz spectroscopy could help Explain water's anomalies

29-Jun-2018

Liquid water sustains life on earth, but its physical properties remain mysterious among scientific researchers. Recently, a team of Swiss researchers used existing THz spectroscopy techniques to measure liquid water's hydrogen bonding. Future efforts with this technique could one day help ...

New material for splitting water

20-Jun-2018

Solar energy is clean and abundant. But when the sun isn't shining, you must store the energy in batteries or through a process called photocatalysis -- in which solar energy is used to make fuels. In photocatalytic water splitting, sunlight separates water into hydrogen and oxygen. The hydrogen ...

A better way to control crystal vibrations

23-May-2018

The vibrational motion of an atom in a crystal propagates to neighboring atoms, which leads to wavelike propagation of the vibrations throughout the crystal. The way in which these natural vibrations travel through the crystalline structure determine fundamental properties of the material. For ...

A potentially cheap, efficient and eco-friendly system for purifying natural gas

08-May-2018

Fundamental researchers at the Colorado School of Mines have proposed a novel two-part system for separating impurities from natural gas. Natural gas primarily contains methane, but impurities in the gaseous mixture need to be removed before the methane can be put into the pipeline. The newly ...

Course set to overcome mismatch between lab-designed nanomaterials and nature's complexity

18-Apr-2018

Cells and the machinery they encase are soft matter -- shape-shifting multicomponent systems with an overwhelming richness of forms. But, these squishy packages are hard targets for potential therapeutic and diagnostic applications that exploit nanomaterials, from quantum dots that light up ...

Diamond-based circuits can take the heat for advanced applications

13-Apr-2018

When power generators like windmills and solar panels transfer electricity to homes, businesses and the power grid, they lose almost 10 percent of the generated power. To address this problem, scientists are researching new diamond semiconductor circuits to make power conversion systems more ...
