Prescient Medical, Inc., a privately held medical device company dedicated to reducing deaths from heart attacks, has unveiled a unique, new catheter-based diagnostic tool, the vPredict(TM) Optical Catheter System, and a new treatment, the vProtect(TM) Luminal Shield, for use in the cardiac catheterization lab.
The plastic laser has come one step closer, with researchers in the US and Japan developing a new way to make luminescent semiconducting polymers emit and confine polarized light. The results could lead to brighter polarized sources for products with LED-type displays, such as portable computers and mobile phones.
NIST researchers have designed and demonstrated a transistor containing quantum dots that can count individual photons. The semiconductor device could be integrated easily into electronics for applications such as quantum key distribution (QKD) for 'unbreakable' encryption using single photons
At the Institut Curie, Simon Scheuring, beneficiary of the Inserm Avenir program and coordinator of the CNRS/Inserm "Atomic force microscopy (AFM) of proteins in native membranes" team, has for the first time observed a diseased tissue at very high resolution using atomic force microscopy (AFM).
DuPont today introduced DuPont(TM) Light Stabilizer 210, a product designed as sun protection for plastics. The product uses extremely small particles of titanium dioxide to efficiently absorb ultraviolet light, protecting plastic and anything it covers from the sun's damaging rays. Because a sizeable percentage of titanium dioxide particles in the product are nanoscale, it was selected as a demonstration case for application of the Nano Risk Framework that DuPont and Environmental Defense introduced in June. The Framework is a systematic and disciplined process to evaluate and address the potential risks of nanoscale materials.
New sol-gel inks developed by researchers at the University of Illinois can be printed into patterns to produce three-dimensional structures of metal oxides with nanoscale features.
After a successful upgrade, the FLASH facility achieved a world premiere by generating flashes of laser light at the minuscule wavelength of 6.5 nanometres (nm), thereby breaking the world record of 13.5 nm it established one year ago. The facility now provides even better research opportunities for the second measuring period, which will begin on November 19, 2007.
Lasers have been used in medicine for many years, mostly as minimally invasive surgical cutting tools. However, in recent years there have been many advances in the market, and the range of applications for lasers and light-based systems continues to expand across several specialities, especially in ophthalmology and cosmetic treatments. This has created a demand for increased efficiency of lasers and high intensity pulsed lamps, while creating new systems that are more compact, gentler, quicker and more cost-effective.
Scientists at the U.S. Department of Energy's Brookhaven National Laboratory have developed a method for correlating the results of microscopic imaging techniques in a way that could lead to improved understanding, diagnosis, and possibly treatment of a variety of disease conditions, including Alzheimer's disease. The Laboratory has filed a U.S. provisional patent application for the invention.
Scientists in India are reporting an advance toward discovering a Holy Grail of the illumination industry ¡X a white LED, a light-emitting diode that produces pure white light suitable for interior lighting of homes, offices and other buildings. Their study is in the Sept. 9 issue of ACS' The Journal of Physical Chemistry C, a weekly publication.
