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.

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.
In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...

For photographers and scientists, lenses are lifesavers. They reflect and refract light, making possible the imaging systems that drive discovery through the microscope and preserve history through cameras.
But today's glass-based lenses are bulky and resist miniaturization. Next-generation technologies, such as ultrathin cameras or tiny microscopes, require...
Scientists from the University of Zurich have succeeded for the first time in tracking individual stem cells and their neuronal progeny over months within the intact adult brain. This study sheds light on how new neurons are produced throughout life.
The generation of new nerve cells was once thought to taper off at the end of embryonic development. However, recent research has shown that the adult brain...
