In the present work, chemical/photochemical processes, specifically, Fenton and Fenton-like reactions were employed to treat a leachate from the municipal solid waste landfill of Astana (Kazakhstan). Each experiment lasted ...

Carbon nanowalls (CNWs) are few-layer graphene nanosheets standing vertically on a substrate. CNWs can be synthesized on various metallic, semiconductor and insulator substrates using various techniques. CNWs demostrate ...

A series of molecules capable of releasing of the strong organometallic Lewis acid B(C6F5)3 upon exposure to 254 nm light have been developed. These photo Lewis acid generators (PhLAGs) can now serve as photoinitiators ...

Imaging surveys will find many tens to hundreds of thousands of Type Ia supernovae in the next decade, and measure their light curves. In addition to a need for characterizing their types and subtypes, a redshift is required ...

A new waveguiding effect in photonic crystals has been discovered. It will be useful for harvesting light for solar energy photovoltaic. We have found that incident light can be efficiently concentrated and redirected along ...

Photonic memory devices are capable of giving different outputs for the same present input, judging from the input’s past values and, in this way, “remembering” what happened the previous times. Nonlinear cylindrical ...

The CAST experiment is designed to search for solar axions which are produced in the dense plasma the interior of the sun via the Primakoff effect. Detection of axions and their energy spectrum will immediately reveal ...

We present results on the photothermal (PT) and heat conductive properties of nanogranular silicon (Si) films synthesized by evaporation of colloidal droplets (drop-casting) of 100 ± 50 nm-sized crystalline Si nanoparticles ...

HTA was introduced in Kazakhstan in 2009 as a result of an agreement of Kazakhstani Government with World Bank. As a consequence of this project, an HTA unit was created as part of Republican Centre of Healthcare ...
