In plasmonics, 'optical losses' could bring practical gain

28-Jan-2016

What researchers had thought of as a barrier to developing advanced technologies based on the emerging field of plasmonics is now seen as a potential pathway to practical applications in areas from cancer therapy to nanomanufacturing. Plasmonic materials contain features, patterns or elements ...

'Hydricity' concept uses solar energy to produce power round-the-clock

17-Dec-2015

Researchers are proposing a new "hydricity" concept aimed at creating a sustainable economy by not only generating electricity with solar energy but also producing and storing hydrogen from superheated water for round-the-clock power production. "The proposed hydricity concept represents a ...

Advance could bring commercial applications for silver nanowires

11-Nov-2015

Silver nanowires hold promise for applications such as flexible displays and solar cells, but their susceptibility to damage from highly energetic UV radiation and harsh environmental conditions has limited their commercialization. New research suggests wrapping the nanowires with an ultrathin ...

Purdue researchers observe phase transition thought impossible

28-Oct-2015

In 1937 physicist Lev Landau established a theoretical framework that explained and classified all of the known phases, but in the late 1980s it was realized that there existed a second group of phases that occur at very low temperatures that do not fit in Landau's theory. The new phases were ...

'Topological insulators' promising for spintronics, quantum computers

18-Nov-2014

Researches have uncovered "smoking-gun" evidence to confirm the workings of an emerging class of materials that could make possible "spintronic" devices and practical quantum computers far more powerful than today's technologies. The materials are called "topological insulators." Unlike ordinary ...

New analytical technology reveals 'nanomechanical' surface traits

01-Sep-2014

A new research platform uses a laser to measure the "nanomechanical" properties of tiny structures undergoing stress and heating, an approach likely to yield insights to improve designs for microelectronics and batteries. This new technique, called nanomechanical Raman spectroscopy, reveals ...

Spinach could lead to alternative energy more powerful than Popeye

01-Aug-2014

Spinach gave Popeye super strength, but it also holds the promise of a different power for a group of scientists: the ability to convert sunlight into a clean, efficient alternative fuel. Purdue University physicists are part of an international group using spinach to study the proteins involved ...

Advance brings 'hyperbolic metamaterials' closer to reality

22-May-2014

Researchers have taken a step toward practical applications for "hyperbolic metamaterials," ultra-thin crystalline films that could bring optical advances including powerful microscopes, quantum computers and high-performance solar cells. New developments are reminiscent of advances that ushered ...

'Problem wells' source of greenhouse gas

16-Apr-2014

High levels of the greenhouse gas methane were found above shale gas wells at a production point not thought to be an important emissions source, according to a study jointly led by Purdue and Cornell universities. The findings could have implications for the evaluation of the environmental ...

Nanotube coating helps shrink mass spectrometers

27-Mar-2014

Nanotechnology is advancing tools likened to Star Trek's "tricorder" that perform on-the-spot chemical analysis for a range of applications including medical testing, explosives detection and food safety. Researchers found that when paper used to collect a sample was coated with carbon nanotubes, ...
