Main scientific results by INP BSU staff in 2012 in the area of fundametnal scientific research
- It was shown that during decelerating of antiprotons in matter the effect of nuclear precession helps obtain the data on real part of scattering amplitude of antiproton on proton (nucleus) at zero energies, i.e. in the range which is not accessible for direct measurement in standard experiments on scattering.
- An experimental mock-up of generator of electromagnetic radiation was manufactured and tested. The generator consists of a virtual cathode, a power supply, which uses direct conversion of chemical energy of explosion into electric. Maximum power of microwave radiation, observed in experiments, reached the level of 200 MW.
- Results pointing at existence of Higgs boson during the process of 2-gamma decay with high mass resolution were obtained on the electromagnetic calorimeter CMS in CERN, which was developed and manufactured with participation of INP BSU.
- Experiments were carried out with sample nanotubes, which are calibrated by length. These experiments point out the unambiguous dependence of spectral position of terahertz absorption peak of thin films made of single-walled carbon nanotubes with their length. It was shown that terahertz peak is formed mainly from a localized plasma (antenna) resonance in single-walled carbon nanotubes. Experimental evidence of antenna properties of nanotubes was found. An effect of deceleration of surface plasmon in nanotubes, which was theoretically predicted previously, was confirmed.
- A method of synthesis of nanotubes, which are calibrated by length with the length of 50-250 nm was developed. The method is an optimized technology of «breaking» of carbon nanotubes during ultrasound processing of their suspension mixed with nitric and sulfuric acids. The method is cheap, simple and highly effective (with yield up to 100%) and is aimed primarily for biophysical and medical applications of carbon nanotubes.
