Oh, Snap: Stressed Sensor Self-Heals
RALEIGH, N.C., June 16, 2011 — One flaw of strain sensors in that they can break under stress. But a new fiber optic strain sensor can heal itself — so in the wake of earthquakes, explosions or other catastrophic events it continues collecting data, helping engineers make informed decisions about structural safety. One flaw of strain sensors in that they can break under stress. But a new fiber optic strain sensor can heal itself — so in the wake of earthquakes, explosions or other catastrophic events it continues collecting...
Unprecedented Spatially Resolved Chemical Analysis Via Nanoscale Spectroscopy
Dec 1, 2010 — The phrase “lab on a tip,” referring to nanoscale property measurements made by the probe of an atomic force microscope (AFM), has been a dream for the developers of analytical instrumentation. There also has been a drive for...
Transparent Material Harvests Light
UPTON, N.Y., Nov. 5, 2010 — Scientists at Brookhaven and Los Alamos national laboratories have fabricated transparent thin films capable of absorbing light and generating electric charge over a relatively large area. Described in the journal Chemistry of Materials, the...
Cut, Mark, Drill, Repeat
Aug 1, 2010 — Increasingly, the medical devices used to support good health and provide emergency and long-term care are not being designed to sit on a rack or table next to a patient’s hospital bed. Instead, they are being made small and light enough to be...
Lasers reinforce lightweight structures
PARIS and AACHEN, Germany – At the JEC Composites Show in Paris, researchers from Germany’s Fraunhofer institutes showed how lasers can make the manufacturing of fiber-reinforced thermoplastic structures more efficient, reliable and automated. Fiber-reinforced plastics...
The Laser’s European Family Tree
Apr 12, 2010 — As we celebrate the 50th anniversary of the date when the first man-made laser saw the light of day, it is important to look back at its birth. And although that beginning took place in the hills of sunny Malibu, Calif., on May 16, 1960, this...
Asylum Orders Surge 60% in Q3
SANTA BARBARA, Calif., Oct. 2, 2009 -- Atomic force and scanning probe microscope maker Asylum Research said its orders for the third quarter are up more than 60 percent, driven largely by the introduction of a new high-resolution AFM, the popularity of two MFP-3D™ AFMs and the...
A closer look at plastic solar cells
Oct 1, 2009 — Plastic solar cells are lightweight, flexible and, most importantly, cheap to make. But so far, these devices lack one thing: efficiency. Now researchers at the University of Washington in Seattle believe that they may have the key to unlocking...
Taking Semiconductor Manufacturing to the Extreme
Oct 1, 2009 — As consumer and enterprise demand for faster computers increases, so will the demand for faster computer chips. The speed of computer chips is directly related to the number of transistors that can fit on a chip. Transistors work like switches...
Ultrafast Laser
Aug 1, 2009 — Fianium has introduced its FP1060-HE high-energy ultrafast fibre laser. Based on a mode-locked model, it can deliver pulse energies >10 μJ with pulse durations to below 20 ps in challenging environments. The platform is based on a modular...
Konarka Hires Former GE Exec
Mar 19, 2009 — Konarka Technologies of Lowell, Mass., has appointed Therese “Terri” Jordan as vice president of business development. A leader in developing markets for new materials and technologies in the field of polymers, she will lead the company’s efforts...
Bruker AXS Buying AFM Maker
KARLSRUHE, Germany, Aug. 18, 2008 -- Analytical x-ray systems manufacturer Bruker AXS GmbH of Karlsruhe, Germany, announced it will acquire the German company SIS (Surface Imaging Systems) GmbH, a maker of advanced atomic force/scanning probe microscopy (AFM/SPM) systems, for an...
High-Throughput Optical Coating
Aug 1, 2008 — Sputtering processes for thin-film deposition are naturally energetic and generally do not require additional heat input to generate good morphology. As a result, sputtering is a suitable deposition technique for heat-sensitive substrates such as...
Nanowires Used to Push Solar Efficiency
Jun 1, 2008 — Solar cell design is critical to how efficiently incoming sunlight is transformed into usable electrical energy. Even slight modifications in architecture or material can have meaningful effects. Numerous polymers have been examined for use in...
Ultrathin Films Resist Bacteria
CAMBRIDGE, Mass., May 16, 2008 -- Inexpensive, easy-to-produce, ultrathin films made of polymers could be applied to medical devices and other surfaces to control microbe accumulation. They could also help reduce the spread of hospital-acquired infections, which take the lives of...
FCS Helps to Track Individual Molecules
During Polystyrene Formation
Feb 1, 2008 — Polymers are very important, whether they are artificial (plastics) or natural (proteins). Various techniques have been used to explore the processes involved in the formation of polymers from simpler molecules. Nuclear magnetic resonance, electron...
Biomedical Polymers Created
ATLANTA, Jan. 8, 2008 -- Unique polymers that change shape upon heating are being developed for biomedical applications such as opening blocked arteries, probing neurons in the brain and engineering a tougher spine. These so-called shape-memory polymers can be...
Looking at Polymers in Three Different Lights
Oct 1, 2007 — The industrial use of polymers is growing, but still required are models that account for physical phenomena such as temperature dependence, thermomechanical coupling and aging. Such models ideally would allow for the reliable predictions of the...
PerkinElmer Acquires Thermal Analysis Line
BOSTON, Jan. 2, 2007 -- PerkinElmer Inc. announced today it has acquired a line of dynamic mechanical analysis (DMA) products from UK-based Triton Technology Ltd. The DMA instrument is used by scientists in the polymers, pharmaceuticals and food industries for applications...
NSF Awards $76M for 4 Sci-Tech Centers
ARLINGTON, Va., Oct. 12, 2006 -- The National Science Foundation (NSF) has awarded a total of $76 million, to be distributed over five years, for four science-technology centers that will address fundamental questions in next-generation polymers, climate modeling, microbial...
Formulating Lenses that Focus on Their Own
Sep 1, 2006 — Researchers at the University of Wisconsin-Madison have devised some smart microlenses that change optical properties, such as focal length, on their own in response to varying environmental conditions. The devices, either singly or in arrays,...
MALDI RECIPES
Sep 1, 2006 — Researchers at the National Institute of Standards and Technology (NIST) have added 150 methods to a database of 255 procedures for analyzing specific synthetic polymers using matrix-assisted laser desorption/ionization (MALDI) mass spectrometry....
Scientists Turn Graphite into Graphene
EVANSTON, Ill., July 24, 2006 -- Researchers have developed a way to turn graphite into graphene, one-atom-thick sheets of carbon that can be mixed into other materials such as glass and ceramics to manipulate properties such as strength and thermal conductivity. The method,...
Confocal Raman Microscope Exposes Diffusion Kinetics
May 1, 2006 — Using confocal Raman microscopy, researchers at the University of Utah in Salt Lake City are measuring the diffusion of molecules into polymer particles. The work could help people get their medicine continuously and could help clean up the...
