Laser Melts Chip Defects
PRINCETON, NJ, May 15, 2008 -- As microchips shrink, even tiny defects in the lines, dots and other shapes etched on them become major barriers to performance. Princeton engineers have now found a way to literally melt away such defects, using a process that could dramatically improve chip quality without increasing fabrication cost. The method enables more precise shaping of microchip components than what is possible with current technology. More precise component shapes could help manufacturers build smaller and better...
Complicated Pulses Measured
ATLANTA, May 12, 2008 -- A device that reveals spherical aberrations in optical components could help biologists, chemists, and other nonlaser scientists easily measure complicated ultrashort laser pulses. Lasers that emit ultrashort pulses of light are used for...
Light Mapped Through Holes
DELFT, Netherlands, May 9, 2008 -- The question of how light squeezes through small holes has been answered by a research team successful in accurately mapping the process for the first time. The researchers -- Aurele Adam, PhD, and professor Paul Planken of Delft University of...
Solder Bumping Improves Lens
JENA, Germany, May 7, 2008 -- A solder technique used in electronics manufacturing is proving useful in keeping optical device lenses clear and in place when they are used inside a vacuum. When cameras and microscopes are placed in a vacuum, their lenses and prisms, usually...
‘Giant’ Nanoparticles May Offer Improved Performance
May 1, 2008 — Although nanocrystal quantum dots offer a host of advantages and continue to be explored for a range of imaging applications, these tiny optical probes do come with some baggage. They are, for instance, prone to changes in their quantum yield,...
A Simpler Way to Build an Optical Acidity Detector
May 1, 2008 — A team of researchers in Spain has devised a fluorescent surface molecular sensor for the detection of acidity. The sensor could find application in industry, clinical analysis and environmental sampling. The team consisted of researchers from...
Capturing the Colors of a Plastic Bubble
May 1, 2008 — Everyone loves the bright rainbow colors of a soap bubble, and young children often cry when these delicate objects burst. However, Fumiyoshi Ikkai of Nihon L’Oreal KK in Kawasaki, Kanagawa, Japan, now has found a way to capture and preserve this...
Gas-Assisted Embossing and UV Curing Combine to Make Microlens Arrays
May 1, 2008 — Individual microlenses may be small, but a large array of them can have a big impact — and present some big challenges. Because microlens arrays are a key optical component in large-format LCD TVs and elsewhere, there is a need for low-cost and...
High-Quality NSOM Aperture Probes Made More Cheaply
May 1, 2008 — Near-field scanning optical microscopes (NSOM) have not been used widely or routinely because of difficulties producing high-quality probes at a reasonable cost. The technique uses probes with holes so tiny that they produce evanescent waves to...
Ivy’s Secret Is in Its Secretions
May 1, 2008 — As anyone knows who has ever been to Wrigley Field in Chicago, ivy climbs, it covers and it spreads over almost anything in its path. The plant’s famed surface-climbing ability has made it a fixture in country gardens, on urban buildings and in...
Practical Nanotomography
May 1, 2008 — The applications of focused ion beam-based nanotomography already are quite diverse and are expanding quickly. Materials science applications range from analysis of volumetric fractions of composition and porosity to crystallographic texture....
Scanning Impedance Probe Microscopy
May 1, 2008 — Mapping physical properties of various materials at high resolution has been pursued for decades in the microscopy world, and new challenges are added by the semiconductor and materials industries, which have an increasing need to map physical...
Visible and Nonvisible Imaging Techniques
May 1, 2008 — The field of industrial microscopy has evolved from simple bright-field on-axis imaging to that of nonvisible and confocal-based technologies. Bright-field is a resolution-limited technique that uses on-axis illumination and imaging to form the...
Cu Nanowires Create Displays
CHAMPAIGN, Ill., April 30, 2008 -- Copper (Cu) nanowires grown at low temperatures and catalyst-free could serve as interconnects in electronic device fabrication and as electron emitters in a very thin flat panel display known as a field emission display. “We can grow forests of...
Paul Newbatt to Lead Business Development at CEMMNT
Apr 30, 2008 — The Centre of Excellence in Metrology for Micro and Nano Technologies (CEMMNT) in Loughborough, England, has named Paul Newbatt as its business development director. Paul has more than 20 years technical sales management experience, having worked...
Neurons Imaged Fast in 3-D
HOUSTON, April 28, 2008 -- A technique that combines a laser beam with a multiphoton microscope allows scientists to quickly observe the function of neurons, or nerve cells, in three dimensions, providing a much better view of their fast activity. Scientists at Baylor...
Straight CNTs Made in Volume
DURHAM, N.C., April 25, 2008 -- Chemists have found a way to grow long, straight carbon nanotubes (CNTs) only a few atoms thick in very large numbers, removing a major roadblock in the pursuit of nanoscale electronics. These single-walled CNTs also follow parallel paths as...
WITec Breaks Ground for New HQ
Apr 25, 2008 — Microscope manufacturer WITec GmbH broke ground earlier this month for new headquarters in Ulm, Germany, to include research, production and office facilities. WITec said the new building, located in a science park next to the University of Ulm, ...
2-D Colloidal Crystal Created
WEST LAFAYETTE, Ind., April 23, 3008 -- A "self-assembling" method could reportedly lead to an inexpensive way to make diamond-like crystals to improve optical communications and other technologies. The method, developed at Purdue University, works by positioning tiny particles onto a...
Laser Study Shines at CLEO
SAN JOSE, Calif., April 23, 2008 -- Detecting dangerous chemicals with lasers, exploring the brain’s circuitry with light, and photoluminescence with nanoneedles will be among the latest breakthroughs in electro-optics, lasers and the application of light waves presented at the...

Apr 22, 2008 — Carl Zeiss SMT AG, a maker of scanning and transmission electron beam systems for nanotechnology, life sciences, material analysis and semiconductor applications, said it will mark the official opening of its new North American headquarters tomorrow...
Fast Probes Outmeasure AFM
ATLANTA, April 18, 2008 -- A new method for material characterization at the nanoscale integrates probe technology based on flexible membranes with a traditional atomic force microscopy (AFM) system to measure multiple properties of biomaterials and other materials...
'FlowCytobot' Detects Blooms
FALMOUTH, Mass., April 15, 2008 -- The Imaging FlowCytobot, an underwater microscope developed as a research tool, recently proved its worth as an early warning device by detecting blooms of harmful marine algae in the Gulf of Mexico and giving authorities time to close areas before...
