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.

Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.
Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...

In the race to produce a quantum computer, a number of projects are seeking a way to create quantum bits -- or qubits -- that are stable, meaning they are not much affected by changes in their environment. This normally needs highly nonlinear non-dissipative elements capable of functioning at very low temperatures.
In pursuit of this goal, researchers at EPFL's Laboratory of Photonics and Quantum Measurements LPQM (STI/SB), have investigated a nonlinear graphene-based...

For the first time, scientists have succeeded in studying the strength of hydrogen bonds in a single molecule using an atomic force microscope. Researchers from the University of Basel’s Swiss Nanoscience Institute network have reported the results in the journal Science Advances.
Hydrogen is the most common element in the universe and is an integral part of almost all organic compounds. Molecules and sections of macromolecules are...
