Siberian researchers have developed a biologically active sorbent of a new generation. The sorbent provides for the 100-percent efficient water purification from microorganisms and bacteriophages. Microbiological researches were performed with partial support of the U.S. Civilian Research and Development Foundation (CRDF) grant.
Specialists of the Tomsk Polytechnical University and Scientific Research Institute “Microorganism Culture Collection” (VECTOR State Research Center for Virology and Biotechnology) have developed a biologically active sorbent of a new generation based on cotton pulp, modified 1-percent silica slip containing activated alumina. The sorbent provides for the 100-percent efficient water purification from microorganisms and bacteriophages, it can be applied in a wide range of conditions and possesses sufficient durability and longevity.
Water and aqueous solutions are overfilled with pathogens, viruses and toxins, which so far threaten life and health of people, regardless of undertaken actions. Water purification via filtering is ineffective and underproductive, as fine filters with low throughput capacity have to be utilized. Contemporary purification methods are based on the fact that the majority of bacteria and viruses are negatively charged, therefore they can be captured by a macroporous material possessing positive electrokinetic potential. As a result of the process called electrokinetic capturing, small particles would simply stick to filter material.

At the LASYS 2018, from June 5th to 7th, the Laser Zentrum Hannover e.V. (LZH) will be showcasing processes for the laser material processing of tomorrow in hall 4 at stand 4E75. With blown bomb shells the LZH will present first results of a research project on civil security.
At this year's LASYS, the LZH will exhibit light-based processes such as cutting, welding, ablation and structuring as well as additive manufacturing for...
There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?
At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...

A team led by Austrian experimental physicist Rainer Blatt has succeeded in characterizing the quantum entanglement of two spatially separated atoms by observing their light emission. This fundamental demonstration could lead to the development of highly sensitive optical gradiometers for the precise measurement of the gravitational field or the earth's magnetic field.
The age of quantum technology has long been heralded. Decades of research into the quantum world have led to the development of methods that make it possible...
