Pores never become clogged in this filter – because there are no pores at all. The filter is designed in a different way.

The device invented by V.B. Krapukhin, Ph. D. (Engineering) was shown for the first time at the recent “Chemistry-2005” exhibition in Moscow where constantly crowded near the exhibition booth. The most heard comment was “simple like everything ingenious”.

The water purification filter looks as follows:

There is a tank containing troubled, evi

A team of researchers at Yale University is the first to devise a way to predict the microstructure of crystals as they form in materials, according to a report in the September issue of Applied Physics Letters.

Although there are theoretical models that predict grain size and ways to monitor the growth of individual crystals, this new method makes it possible to estimate grain size and therefore the properties of materials that are dependant on microstructure.

Having vital location or map-based information at their fingertips could make the difference between life and death for rescue workers and emergency services working at the scene of a natural disaster or terrorist attack.

A research centre is being launched at The University of Nottingham to look at how the latest advances in computer software and mobile communications could help agencies to prepare for a major event, such as the 2012 Olympic Games, and plan their response should a

The Planetary Fourier Spectrometer (PFS) on board ESA’s Mars Express spacecraft is now back in operation after a malfunction, reported a few months ago.

The instrument had been successfully investigating the chemical composition of the Martian atmosphere since the beginning of 2004, when Mars Express began orbiting the Red Planet. PFS is a very sensitive instrument, capable of measuring the distribution of the major gaseous components of the atmosphere, the vertical distribution

Veteran CU-Boulder scientist on camera team

University of Colorado at Boulder planetary scientist Larry Esposito, a member of the European Space Agency’s Venus Express science team, believes the upcoming mission to Earth’s “evil twin” planet should be full of surprises.

While its 875-degree F. surface is hot enough to make rocks glow and its atmosphere is filled with noxious carbon dioxide gases and acid rain, Venus actually is more Earth-like than Mars, said Esposito,

Bringing the study of lightning research into the laboratory

Lightning, a high-voltage discharge that strikes quickly and sometimes fatally, is very difficult to study. A new and surprising finding by Florida Institute of Technology’s Dr. Joseph Dwyer and his team brings the study of lightning research into the laboratory.
Already noted for his discoveries related to x-ray emission from natural and triggered lightning, Dwyer, an associate professor of physics and space sciences

Laboratory experiments at UCR demonstrate interactions between two atoms containing antimatter

What happens when two atoms, each made up of an electron and its antimatter counterpart, called the positron, collide with each other? UC Riverside physicists are able to see for the first time in the laboratory that these atoms, which are called positronium atoms and are unstable by nature, become even more unstable after the collision. The positronium atoms are seen to destroy one a

John Federici, PhD, professor, department of physics, New Jersey Institute of Technology (NJIT) and other physicists at NJIT recently received a U.S. Patent for a Teraherz imaging system and method. Since 1995, Terahertz imaging has grown in importance as new and sophisticated devices and equipment have empowered scientists to understand its potential.

“I see the Terahertz spectrum as one of the critical technologies for defense against suicide bombers and other terrorist activit

A far reaching analysis of the potential futures faced by Europe’s information communication technologies (ICT) sector in a global context is laying detailed and incisive groundwork for policy makers to improve Europe’s situation by guiding ICT developments over the medium to long term.

“FISTERA aimed to investigate long-term trends in ICT to make a foresight analysis of changes in information communication technologies and uses by 2020,” says Ramón Compañó, of the Institute fo

Results from experiments conducted at the University of California, Santa Barbara may lead to profound changes in optical communications. The discovery is reported in the October 28th edition of the journal Science.

Physicist Mark Sherwin at UCSB explained that as information technology advances, scientists are intent on transmitting information much more quickly. “We are working toward sending information 100 times faster than it can be sent now,” he said. His research group h

Today, most computer and consumer electronic devices require wires to record, play or exchange data. UWB (Ultra Wide Band) eliminates the need for such wires freeing people to perform activities such as remotely connecting their mobile PC to a printer, streaming audio from an MP3 player to speakers, or wirelessly transferring digital pictures to a photo print kiosk.

A physicist and a medical researcher at the University of Leicester have received a grant of £100,000 from the Engineering and Physical Sciences Research Council to look at possible toxic damage from inhaled nanoparticles used for a range of everyday purposes.

The small size of nanoparticles in the size range 5-100 nm gives many novel and useful properties and they are used in applications as diverse as face creams, plastics, medical imaging, novel drug therapies and magnetic r

New findings from members of the Cassini imaging team show that certain prominent features in Saturn’s narrow and contorted F ring can be understood in terms of a simple gravitational interaction with the small moon Prometheus. The results are published in today’s issue of the journal “Nature.”

The F ring is notorious for exhibiting unusual structures, like “knots,” “kinks,” and “clumps” that continue to puzzle astronomers. Cassini images have shown that the gravitati
