In non-contact displacement measurement applications, engineers often overlook the effects of temperature variations on the measurement accuracy of the sensor. It is therefore critical to check supplier datasheets, says Chris Jones
Whether we are talking about intermediate or final cleaning, the purpose of industrial parts cleaning is to ensure the necessary degree of cleanliness for subsequent processing, or for the long-term, trouble-free functioning of the relevant part or component. Although the required standard of cleanliness (meaning the absence of particulate residues and/or surface films) can vary greatly depending on the particular operation and sector involved, the ultimate aim is to achieve – and in many cases also to document – the desired outcome consistently, quickly, and at the lowest possible cost. Another challenge often faced is to maintain the condition of a work-piece’s surface until it undergoes further processing.
Two or four single lead-salt detector elements are assembled within a single TO-39 or TO-8 housing each with its own IR optical filter, supplied from either one of many LASER COMPONENTS’ standard optical filters or a custom designed optical filter. Free issue filters or windows can also be used. The popular detector element of choice measures 1mm x 1mm square. Single channel detectors usually employ 2mm x 2mm square elements.
They say diamonds are forever, but in fact they are a metastable form of carbon that will slowly and ultimately transform into another form of carbon, graphite. It would be of great potential if materials designers could design and synthesize other long-lasting, thermodynamically metastable materials. However, this has yet to become a reality due to the lack of rational understanding of them.
Scientists have developed a new dry adhesive that bonds in extreme temperatures, a quality that could make this product suitable for space exploration and beyond. The adhesive was developed by researchers from Case Western Reserve University, Dayton Air Force Research Laboratory, and China.
As part of the Electronics Assembly with Phil Zarrow video series, Indium Corporation's Bill Jackson, Director and General Manager of Compounds, and SMT expert Phil Zarrow, President and Principal Consultant for ITM Consulting, discuss the applications of indium.
Magritek, a leading provider of compact NMR and MRI instruments, reports on how the Centre of Expertise on Sustainable Chemistry at Karel de Grote University College in Antwerp is using a Spinsolve benchtop NMR spectrometer in both teaching and research.
The Molecular Microscopy and Spectroscopy group togheter with the Nanoscopy group at the Istituto Italiano di Tecnologia (IIT, Genova, Italy) have significantly reduced the photobleaching effect in STED (STimulated Emission Depletion) microscopy without the reduction of the spatial resolution by combining the time-gated detection technique with the use of the subnanosecond fiber laser Katana HP as STED laser beam [1]. This result brings one step further the development of commercially available super-resolution microscopes.
In the world of big data, there are limitations on storing large volumes of information. Typical home-computer hard disk drives use up a lot of power and are limited to a few terabytes per drive. Optical storage media such as Blu-ray and DVD, are energy efficient and inexpensive, however storage densities are very low because of the optical diffraction limit and planar nature of the discs. However, scientists have made progress on creating a 3D diamond chip capable of storing vastly more data compared to existing technologies.
The magnetic properties of materials have inspired technologies from traditional recording tape to advanced hard drives over the years. Scientists are continually pushing to develop new applications from magnetic behavior.
