Continuously Variable Attenuator with Brewster type polarizers.This variable attenuator/beamsplitter consists of 2 high-performance polarizing optics components placed in precision opto-mechanical Holder 5APH79T-1. The variable attenuator/beamsplitter incorporates 2 high-performance Brewster type polarizers, which reflect s-polarized light while transmitting p-polarized light. These two Brewster type polarizers are housed in special design opto-mechanical Adapter. This adapter allows to use either round shape either rectangular shape Brewster type polarizers as well. A rotating quartz Phase λ/2 Waveplate is placed in the incident polarized laser beam. The intensity ratio of those two beams may be continuously varied without alteration of other beam parameters by rotating ...

An Electric double-layer capacitor, also known as supercapacitor, supercondenser, pseudocapacitor, electrochemical double layer capacitor (EDLC), or ultracapacitor, is an electrochemical capacitor that has an unusually high energy density when compared to common capacitors, typically on the order of thousands of times greater than a high capacity electrolytic capacitor. For instance, a typical D-cell sized electrolytic capacitor will have a capacitance in the range of tens of millifarads. The same size electric double-layer capacitor would have a capacitance of several farads, an improvement of about two or three orders of magnitude in capacitance, but usually at a lower working voltage. Larger double-layer capacitors have capacities up to 5,000 farads as of 2010. The highest energy densit...

The new N-Series poppet valves are an innovative, compact design with an MTBF of 3 million cycles. A bellows-sealed stem and electropolished stainless steel body provides long life even in the most demanding applications. Standard pnuematic actuation is normally closed (Air-to-Open / Spring-to-Close). N-series valves are available in right angle or angle-in-line body styles with tube ends, NW flanges and CF rotatable flanges. Optional air solenoids are available in multiple voltages and can be ordered factory installed or as separate kits for easy field installation.Mounting slots for optional position indicators are incorporated into the actuator body resulting in a reduction in overall size and elimination of the risk of physical damage to the sensors. Sensors are easily installed withou...
When a team of German physicists discovered a new way of using a scanning tunnelling microscope (STM) to take images of molecules at the atomic scale for the first time, everybody was happy and started find ways to improve the technique in order to obtain better images.The main task was to discover WHY it was providing such good images.Now, after two years of research the physicists may have solved the mystery. It seemsthat the improvement is caused by Pauli repulsion. This is a short-range force that arises from the fact that two or more electrons cannot occupy the same quantum mechanical sta...
A new watter purifying method has been developed by dipping plain cotton cloth in a high-tech broth full of silver nanowires and carbon nanotubes. Instead of trapping bacteria,like the classical filters do, the new device lets them flow through with the water, killing all the pathogens with an electrical field that runs through the highly conductive "nano-coated" cotton.The lab test have proved a 98% efficiency in killing Escherichia coli bacteria. Add to this the fact that the new filter is energetically efficient and it can be produced at low costs and we have an extremely su...
Ultrafast time-resolved laser spectroscopy is a technique that uses very short laser pulses to study the properties of physical systems.Generating isolated laser pulses, that last a few auttoseconds - quintillionths of seconds- is not an easy task. A team of researchers from the RIKEN Advanced Science Institute in Wako, Japan, in collaboration with scientists at the Vienna University of Technology, Austria, have now created a new method of producing isolated auttosencod pulses. Takahashi says that this method could produce isolated, extreme-ultraviolet x-ray pulses ...
The classical theory of ferromagnetism states that in magnetic materials, the individual magnetic moments of the atoms that toghether comprise the magnetism of the material ale all aligned parallel, and identically orientated. A team of researchers from the RIKEN Advanced Science Institute, Wako, Japan have discovered a rare arrangemt of magnetic moments, called skyrmions. To observe the new arrangement, the researchers have used a Lorentz transmission electron microscope, suitable for imaging magnetic structures at very high resolution. Read the entire article...
Multiview video coding (MVC), the new standard for 3-D movie compression promises to allow watching 3D movies on the Internet since it's providing great high-resolution quality while reducing the data significantly.3D movies require higher data rates than 2D movies since at least two images are needed for the spatial representation. That's why, finding an efficient way of transmitting 3D movies is crucial.On the Internet movies have to load quickly so the user can watch movies without interruptions.The new standard, MVC, packs two images needed to create the 3D effect so that the bit rat...
In the future, our clothes could be our batteries as well. The scientists have developed new materials for the battery's cathode, or positive electrode that could be woven into fabrics such as uniforms or ballistic vests, and poured or sprayed into containers of any size and shape.Once woven into clothing, the new batteries could provide power for various electronic devices. The new technology helps creating flexible batteries that will have minimal loss of power and will have better performances that the batteries built using present technologies.

Keeping the dust away from surfaces about the size of 25 or 50 football fields is one of the major concerns of the companies deploying large-scale solar power installations. The solution seems to come from the space mission on Mars: self-dusting solar panels.The new panels would have a self cleaning coating that will keep them clean, especially in areas of high dust and particulate pollutant concentrations. Since most of the large-scale solar installations are usually located in sun-drenced desert areas, using water to keep them clean can be extremely expensive. This is where a sel...
