    Full text link
    The status of the experiment on the precise Ο„\tau lepton mass measurement running at the VEPP-4M collider with the KEDR detector is reported. The mass value is evaluated from the Ο„+Ο„βˆ’\tau^+\tau^- cross section behaviour around the production threshold. The preliminary result based on 6.7 pbβˆ’1^{-1} of data is mΟ„=1776.80βˆ’0.23+0.25Β±0.15m_{\tau}=1776.80^{+0.25}_{-0.23} \pm 0.15 MeV. Using 0.8 pbβˆ’1^{-1} of data collected at the Οˆβ€²\psi' peak the preliminary result is also obtained: Ξ“eeBττ(Οˆβ€²)=7.2Β±2.1\Gamma_{ee}B_{\tau\tau}(\psi') = 7.2 \pm 2.1 eV.Comment: 6 pages, 8 figures; The 9th International Workshop on Tau-Lepton Physics, Tau0

    The first lasing near the wavelength of 140 Β΅m was achieved in April 2003 using a high-power free electron laser (FEL) constructed at the Siberian Center for Photochemical Research. In this paper we briefly describe the design of the FEL driven by an accelerator–recuperator. Characteristics of the electron beam and terahertz laser radiation, obtained in the first experiments, are also presented in the paper.Π£ Π‘ΠΈΠ±Ρ–Ρ€ΡΡŒΠΊΠΎΠΌΡƒ Ρ†Π΅Π½Ρ‚Ρ€Ρ– Ρ„ΠΎΡ‚ΠΎΡ…Ρ–ΠΌΡ–Ρ‡Π½ΠΈΡ… Π΄ΠΎΡΠ»Ρ–Π΄ΠΆΠ΅Π½ΡŒ навСсні 2003 Ρ€ΠΎΠΊΡƒ ΠΎΡ‚Ρ€ΠΈΠΌΠ°Π½Π° гСнСрація Π²ΠΈΠΏΡ€ΠΎΠΌΡ–Π½ΡŽΠ²Π°Π½Π½Ρ Π· довТиною Ρ…Π²ΠΈΠ»Ρ– 140 ΠΌΠΊΠΌ Π½Π° ΠΏΠΎΡ‚ΡƒΠΆΠ½ΠΎΠΌΡƒ Π»Π°Π·Π΅Ρ€Ρ– Π½Π° Π²Ρ–Π»ΡŒΠ½ΠΈΡ… Π΅Π»Π΅ΠΊΡ‚Ρ€ΠΎΠ½Π°Ρ… (Π›Π’Π•).

    Water purification from chlorobenzenes using heteroatom functionalized carbon nanofibers produced on self organizing Ni Pd catalyst

    The development of effective methods for the processing of hazardous wastes containing chlorinated hydrocarbons still remains a big challenge. Herein, the approach allowing the transformation of chlorohydrocarbons into functionalized carbon nanomaterials was demonstrated for 1,2 dichloroethane DCE used as a model compound. Carbon nanofibers CNF doped with nitrogen and oxygen heteroatoms were fabricated by a joint decomposition of DCE and co reagent CH3CN, NH4OH, C2H5OH, and H2O . The Ni Pd 5 alloy was used as a catalyst precursor for the CNF synthesis. Pristine Ni Pd alloy was found to undergo disintegration under the reaction conditions and to induce an active growth of the functionalized carbon nanofibers. The obtained CNF were shown to have a similar segmental structure of carbon filaments and to possess high specific surface area up to 470 m2 g and porosity up to 0.9 cm3 g . According to X ray photoelectron spectroscopy data, the nitrogen content within CNF samples prepared using N comprising precursors was about 1.0 1.7 at . The total oxygen content reaches 3.6 at . The obtained materials were demonstrated to be attractive for the dichlorobenzene adsorption from its aqueous solution
