The small device invented and developed by the St. Petersburg chemists can be easily hold in hand. It allows to perform real-time control of mercaptans content in petroleum derivatives – these sulfur compounds are extremely undesirable in gasoline.

In general, nobody likes these sulphur compounds. Besides, they reek – but fortunately, we rarely come across this property. More often they play mean tricks remaining unrecognized since even a small doze of these harmful substances

The first Norwegian-built satellite was launched yesterday from a Russian space base

The Norwegian satelite, called NCBUE-2 measures 10x10x10 centimeters and weighs one kilo.

A group of 80 students have built the satellite, which contains 1000 components, including a miniature computer, antennae, steering systems, solar panels and batteries.

The Agricultural University of Norway is primarily responsible for deciding which tasks the satellite is to carry out. The s

In her PhD thesis at the Public University of Navarre, Industrial Engineer Marta Barreras Carracedo put forward a new method of designing controllers based on QFT (Quantitative Feedback Theory) and which facilitates its real implantation in the government of real physical processes. The thesis itself validates the method putting into practice two concrete cases, an industrial electric furnace used for the drying of large pieces of composite and a heat exchanger in a solar water-heating plant.

Light can carry data at much higher rates than electricity, but it has always been too expensive and difficult to use light to transmit data among silicon chips in electronic devices. Now, electrical engineers at Stanford have solved a major part of the problem. They have invented a key component that can easily be built into chips to break up a laser beam into billions of bits of data (zeroes and ones) per second. This could help chips output data at a much higher rate than they can now.

You fill up your “empty” fuel tank at the gas station and the pump charges you for more gallons than the tank’s rated capacity. Are you being deliberately overcharged?

Unauthorized tampering with pumps does happen, even though state and local weights and measures officials regularly check gasoline pumps to ensure their accuracy. But there are also legitimate reasons for a discrepancy between the amount of fuel metered by a gas pump and an automobile’s rated fuel ta

Berkeley Scientists Synthesize Cheap, Easy-to-Make Ultra-thin Photovoltaic Films

Imagine a future in which the rooftops of residential homes and commercial buildings can be laminated with inexpensive, ultra-thin films of nano-sized semiconductors that will efficiently convert sunlight into electrical power and provide virtually all of our electricity needs. This future is a step closer to being realized, thanks to a scientific milestone achieved at the U.S. Department of Energy
