The aim of this work is to graft bio-groups on the silk fibroin(Bombys mori) by the atmospheric pressure glow discharge(APGD) plasmas for further immobilizing antimicrobial *** an exploration,the polymers of acrylic acid(PAA) were deposited on the silk fibroin film(SFF) by argon(Ar) and nitrogen(N) APGD *** polymers properties were characterized by the contact angle measurement(CA),FTIR,XPS and AFM,*** revealed that the CA of the silk fibroin film could be decreased from 70°to 34°,and the density of carboxyl group was improved greatly when the silk fibroin was modified by PAA. Therefore,antimicrobial peptides will be immobilized on the silk fibroin,and the bio-film with satisfactory antimicrobial activity can be achieved.

In the HT-7 tokamak,heat transport analysis is carried out for the lower hybrid current drive (LHCD) *** and ions are coupled and good confinement can be obtained by properly optimizating LHCD and plasma *** the conditions that the plasma current is about 220kA,the lower hybrid wave(LHW) power is about 300 kW and the central line-averaged density is about 1.5×10 cm,lower hybrid wave power deposition is off-axis. Local transport analysis illustrated that both electron and ion thermal diffusivities are decreased during the LHW phase,and the electron internal transport barriers(eITBs) are formed while been accompanied by the ion internal transport barriers(iITBs) during LHW *** are heated by electron-ion collision in the region of the barriers although the ohmic power and the LHW power were absorbed by the *** electron temperature and ion temperature are increased during the LHW phase,and in the confinement region,the electron-to-ion temperature ratio,T/T varies from 2.0~2.5 during OH phase to 1.3~1.6 during LHW injected into the plasma,which shows that electron confinement is not degraded by the electron-ion collisions meanwhile ions are also *** energy confinement is increased from 13ms to 25ms due to the formation of electron and ion internal transport barries after the LHW is injected into the *** driven current and bootstrap current contribute to 60%of the total current.

The removal of low concentration toluene from air stream by dielectric barrier discharge (DBD) serially combined with manganese oxide octahedral molecular sieve(OMS-2-type) catalytic post-treatment has been investigated in atmospheric pressure and room temperature Plasma catalysis is found to be more effective at destroying toluene than both conventional thermal-catalysis and plasma *** toluene conversion was greatly enhanced by combining DBD with the OMS-2 in a two-stage *** high concentrations of ozone produced in the discharge zone can be used to further oxidize toluene and residual pollutants on OMS-2 catalyst in the *** efficient decomposition of O on OMS-2 at ambient temperature leads to the formation of reactive oxygen species susceptible to react with toluene and residual pollutants in the *** results in a significant increase of toluene destruction and removal ***,the catalytic post-treatment greatly enhances the conversion of toluene into ***,the synthesized manganese oxide OMS-2 materials have been characterized by XRD,TGA,BET and SEM techniques All the materials showed the OMS-2 type(cryptomelane) X-ray diffraction patterns and good thermal stability and high BET surface *** ease of reversible evolution of lattice oxygen,together with the high porosity,and acidity,seems to lead to the excellent properties of OMS-2.
