Scientists of the research group of Prof. Dr. Alfred Meixner and Dr. Dai Zhang from the Institute of Physical and Theoretical Chemistry at the University of Tübingen have developed a near-field microscope that can measure the optical properties of e. g. semiconductor thin films with a spatial resolution and sensitivity long thought unachievable due to fundamental physical laws (diffraction limit). Both the optical spectrum and the topography of a surface can be mapped simultaneously with nanometre precision – a nanometre corresponding to one millionth of a millimetre.
The Optical Society (OSA) is pleased to announce that Optics InfoBase, its online library of journals, co-published journals and conference proceedings, has added the Journal of the Optical Society of Korea (JOSK) to its content offerings. JOSK is the leading English-language optics journal in Korea, and publishes peer-reviewed, open-access content in all areas of optical science and technology.
MWH Laboratories, a division of MWH, the global wet infrastructure sector leader and provider of environmental engineering, construction and strategic consulting services, has introduced a new method to identify the presence of wastewater in ground and surface waters.
Clock keeps time to 1 second in 3.7 billion years
3SAE Technologies, Inc. today announced it has signed a consulting and distribution agreement with DPM Photonics to make 3SAE Technologies’ new large diameter fiber fusion splicing and preparation technologies available to high power fiber laser manufacturers and to military, aerospace, and industrial medical markets throughout the United States.
“Optical methods for particle size and zeta potential determinations with an overview of acoustical techniques” will be the subject of a presentation in March 2010 by Fraser McNeil-Watson, manager of the Novel Measurement Group at Malvern Instruments at a meeting on the ‘Characterisation of sub-micron and nano-sized particles’. The one-day technical meeting, organised by the Particle Characterisation Interest Group of the Royal Society of Chemistry and The Joint Pharmaceutical Analysis Group, takes place on 17 March 2010 at the Royal Pharmaceutical Society in London (UK). The programme includes presentations on different methods available for submicron and nano-sized particle characterisation and will discuss method validation and checking, as well as exploring important aspects of sample preparation and dispersion.
SPIE eBooks have moved out of beta development into full launch on the SPIE Digital Library. The launch includes 120 SPIE Press titles from the Field Guides, Monographs, and Tutorial Texts series. Over the course of 2010 at least 15 new titles and editions will be added to the SPIE eBooks collection, followed by print publication.
Northrop Grumman Corporation (NYSE:NOC) has been selected by ITT Corporation (NYSE:ITT) to provide flight cryocoolers for the sensor payloads for two international weather satellites. The geostationary satellites will provide round-the-clock weather forecasts and severe weather alerts. Cryocoolers are used to reduce thermal noise in space-based sensors.
Nanotools enable imaging, quantification, fabrication, and modeling of a substance/material at the nano level. Several institutions and enterprises including government, private investors, corporate, and academic organizations are funding research-based operations, to develop applications incorporating nano-scale technologies. Nanotools market in the United States is witnessing growth in intellectual property litigations owing to patent infringements. Advances in instrumentation technologies are increasingly impacting the future of nanotechnology. Instruments encompass "nanotools" that aid in observing, measuring, and engineering nanostructures.
To commemorate Low Vision Awareness Month this February, Dr. Sheldon Smith, optometrist at Low Vision of Michigan, P.C., is offering free evaluations to patients diagnosed with retinitis pigmentosa (RP), a leading cause of low vision, in hopes that they might be candidates for a brand-new device designed to enhance or restore sight.
