Mixed Polyanion Glass Cathodes: Glass-State Conversion Reactions

Silicate glass coated microchannels through a phase conversion process for glass-like electrokinetic performance.

The surface modified polydimethylsiloxane (PDMS) microchannels show a much more inferior performance to the durable and reproducible glass chip. In this paper, a facile approach to preparing a silicate glass modified PDMS microchannel for glass-like performance is presented. This glass-like performance is made possible by a phase conversion of a preceramic polymer--allylhydridopolycarbosilane (...

Spin glass state in doped La2CuO4

The lightly doped La2CuO4 of the high temperature superconducting Cu oxides shows spin glass behavior at very low temperatures, which reflects the effects of quantum fluctuations and frustration upon doping. Recent neutron scattering experiments revealed a formation of spin stripes at the same low concentration of doping. A specific relation between the two important properties of spin glass be...

بررسی فرمولاسیون الیاف e-glass و ecr-glass جهت استفاده در لوله های فاضلاب

الیاف شیشه، الیاف ظریف خمش پذیری از خانواده شیشه با اجزاء اصلی sio2-al2o3-cao-mgo و ناخالصی های قلیایی، اکسید های معدنی tio2,fe2o3 و افزودنی b2o3 و فلئور می باشد و در حالت مذاب بصورت رشته های نخی شکل، رشته رشته می شود.الیاف شیشه به دو گروه اصلی پشم شیشه و الیاف پیوسته تقسیم بندی می شود و الیاف شیشه نیز بر حسب شرایط مصرف به چندین نوع e-glass , a-glass, c-glass , r-glass , s-glass , ecr-glas...

Through the Looking Glass: Faraday Conversion in Turbulent Blazar Jets

Faint levels of circular polarization (Stokes V) have been detected in several relativistic jets. While typically less than a few percent, circular polarization can give us critical insight into the underlying nature of the jet plasma. Circular polarization can be produced through a process known as linear birefringence, in which initially linearly polarized emission produced in one region of t...
