Laser-fabricated crystals in glass are ferroelectric
Laser-generated crystals confined in glass retain controllable ferroelectric properties
30-Jan-2019
A team of researchers from Lehigh University, Oak Ridge National Laboratory, Lebanon Valley College and Corning Inc. has demonstrated, for the first time, that crystals manufactured by lasers within a glass matrix maintain full ferroelectric functionality. "This includes the ability to uniformly ...
Nuclear fusion:burning questions on the control of 'burning plasmas'
26-Oct-2018
What would it take to meet the world's energy needs, sustainably, far into the foreseeable future? Perhaps creating energy the way the sun does, through nuclear fusion. Fission and fusion are very different nuclear reactions, according to Eugenio Schuster, Professor in the Department of ...
Electrochemically-produced ammonia could revolutionize food production
11-Jul-2018
Steven McIntosh wants to transform the way ammonia is produced. He hopes to create a viable alternative to the conventional method, which uses massive amounts of energy and emits harmful carbon dioxide. He's exploring a sustainable electrochemical method to efficiently drive the chemical reaction ...
Unexpected degree of order found in interior grain boundaries of polycrystalline materials
11-Oct-2017
Scientists in the United States and China have announced a discovery that they believe could enable the engineering of alloyed materials that are stronger and more ductile and possess superior electrical, magnetic and physical properties. The researchers said they had found a surprising degree of ...
Direct conversion of methane to methanol
Catalyzed by gold-palladium nanoparticles
11-Sep-2017
Liquid methanol is widely used as a feedstock for other chemicals and also has considerable potential as an alternative fuel source. However, converting methane--the primary component of abundant natural gas--into methanol is currently achieved by an indirect process which requires high heat and ...
Tunneling a path to low cost, high efficiency solar cells
08-Sep-2017
Lowering the cost of solar cell production and making it more affordable to individuals and businesses could be a game-changer for the energy sector. That is one of the reasons behind the U.S. Department of Energy's 2011 launch of the SunShot Initiative, a national effort to drive down the cost ...
A more complete picture of the nano world
28-Aug-2017
They may be tiny and invisible, says Xiaoji Xu , but the aerosol particles suspended in gases play a role in cloud formation and environmental pollution and can be detrimental to human health. Aerosol particles, which are found in haze, dust and vehicle exhaust, measure in the microns. One micron ...
Atomic-level activity of green catalyst used in PVC production revealed
03-Apr-2017
An international group of scientists has unlocked the secret of a gold-based catalyst that is responsible for a new, environmentally friendly method of producing the vinyl chloride monomer (VCM) that is used to manufacture polyvinyl chloride (PVC), the world's third-most widely used ...
Scientists fabricate a new class of crystalline solid
A 'subtle' laser heating technique causes atoms to assemble into a rotating lattice
04-Nov-2016
Scientists at Lehigh University, in collaboration with Lawrence Berkeley National Laboratory, have demonstrated the fabrication of what they call a new class of crystalline solid by using a laser heating technique that induces atoms to organize into a rotating lattice without affecting the ...
Making lasers cool again
02-Nov-2016
Once the preferred weapon of B-movie madmen and space-fiction heroes alike, the laser -- a device that generates an intense beam of coherent electromagnetic radiation by stimulating the emission of photons from excited atoms or molecules -- has grown a bit domesticated of late. These days, it has ...
