Laser Method Creates Strong Materials for Flexible Electronics
TOMSK, Russia, March 8, 2021 — A method that integrates metals into polymers for the formation of electrically conductive composites uses laser pulses to irradiate aluminum nanoparticles onto polyethylene terephthalate (PET) substrates. Researchers from Tomsk Polytechnic University (TPU), with international collaborators, formulated the laser-driven integration method, which has implications for flexible electronics. The process locally formed a conductive composite in irradiated areas. TPU
Shaping Light-Activated Nanocatalysts
HOUSTON, Sept. 25, 2020 — A comparative study from Rice University researchers in the college’s Laboratory for Nanophotonics (LANP) demonstrated how the shape of nanoparticles affects their ability to drive light-activated reactions. The work is part of LANP’s...
Femtosecond Lasers Etch Superwicking Metal Surface for Water Purification System
ROCHESTER, N.Y., Aug. 3, 2020 — Led by Chunlei Guo, a professor in the University of Rochester’s Institute of Optics, a team of scientists has demonstrated how ultrashort femtosecond laser pulses etch the surface of a sheet of metal (in this research, aluminum) into a super...
Fiber Laser Welding Cuts Costs and Improves Results
Apr 12, 2017 — Most traditional — i.e., nonlaser — welding techniques currently in use are variations of arc welding. In these methods, two pieces of metal are first brought into contact or close physical proximity. The edges of the pieces may have...
Laser Welding Joins the Lightweighting Trend
Sep 20, 2016 — To return the Cadillac brand to the global prestige luxury stage, General Motors threw as much as it could — 13 materials in all — into the sedan’s body to make it the lightest vehicle in its class. And then to join this...
Biomimetic Photodetector Distinguishes Color
HOUSTON, Aug. 26, 2014 — A new photodetector mimics living organisms’ ability to sense colors, enhancing color filtering and selectivity. The biomimetic color photodetector, developed at Rice University’s Laboratory for Nanophotonics (LANP), uses an aluminum...
NASA Engineer to Complete First
3-D-Printed Space Camera
GREENBELT, Md., Aug. 7, 2014 — New imaging instruments made using 3-D printing could bring the benefits of such technology to the forefront. NASA aerospace engineer Jason Budinoff is developing a 350-mm dual-channel imaging telescope and a 50-mm camera whose outer tube, baffles...
Nanoscale Features Used to Color Plastics
KONGENS LYNGBY, Denmark, July 31, 2014 — Nanoscale structures could one day take the place of dyes in the production of colored plastics. A team from the Technical University of Denmark has found a more environmentally friendly way to produce such plastics, using the shapes of materials...
‘Metamirror’ Doubles Incident Light Frequency
AUSTIN, Texas, July 8, 2014 — A nanostructure produces nonlinear effects a million times greater than traditional, macro-scale nonlinear crystals, according to a team of researchers from Texas and Germany. This “metamirror” could enable miniaturized laser systems and...
Process Combines Arc, Laser Welding
HANNOVER, Germany, July 8, 2014 — A new hybrid laser welding technique could reduce processing time and costs associated with manufacturing tanks and pipelines for liquid gas. Developed at Laser Zentrum Hannover eV (LZH), the approach teams a 16 kW solid-state disk laser with two...
Nanosensors on CDs Simplify Bio Sample Study
MADRID, March 17, 2014 — CD players have been overshadowed by mp3 files in the entertainment world, but in the biology lab, they could be the wave of the future.
Optical Nanocavity Boosts Light Absorption
BUFFALO, N.Y., SHANGHAI and SHENYANG, China, Feb. 27, 2014 — An optical nanocavity that boosts light absorption in ultrathin semiconductors could potentially improve solar cells and cameras, and maybe even harvest energy more efficiently. Currently in development by an international team from the University...
Inrad Optics, IBC Advanced Alloys to Collaborate
VANCOUVER, British Columbia, Canada, and NORTHVALE, N.J., Oct. 19, 2012 — IBC Advanced Alloys Corp. and Inrad Optics Inc. have signed an agreement to identify alternative uses for IBC’s proprietary alloys.
Plasmonics Creates Invisible Photodetector
STANFORD, Calif., May 23, 2012 — An invisible light-detecting device that can see without being seen was created using plasmonic cloaking and could lead to a new class of devices that controls the flow of light at the nanoscale to produce both optical and electronic functions.
Alternatives Sought for Rare-Earth Materials
Dec 1, 2011 — In response to the shortage of rare-earth metals used for polishing in the optics industry, high-tech industry association Spectaris has developed a “Rare Earth” industrial consortium project to seek out possible alternatives. Export...
Metamaterials Pave Way for Superlens
ITHACA, N.Y., Nov. 11, 2011 — Casting tiny, oddly shaped metal structures inside plastic molds could give a boost to creating metamaterials for making “superlenses” that can image proteins, viruses and DNA. Metamaterials, which offer new ways to manipulate...
Alternatives Sought for Rare-Earth Materials
BERLIN, Oct. 14, 2011 — In response to the shortage of rare-earth metals used for polishing in the optics industry, high-tech industry association Spectaris has developed a “Rare Earth” industrial consortium project to seek out possible alternatives. ...
Historic Lasers Find New Life in Niche Applications
Sep 1, 2011 — With all the hoopla surrounding new high-brightness lasers such as disk and fiber, some think the death knell is sounding for CO2, lamp-pumped and other older, well-established types. However, the lack of a one-size-fits-all laser means these...
Laser analysis used for mining
AACHEN, Germany – As demand for minerals and other natural resources increases, so does the need for optimizing mining techniques. Fraunhofer Institute for Laser Technology has developed a laser analysis system that can identify potential mineral reserves. As...
