RuO2 nanorods on electrospun carbon nanofibers were simply grown by precipitation and recrystallization methods for studying their capacitive behaviors for supercapacitor applications. Recrystalliz...

A simple but controllable way of altering the surface nature of carbon fibers, without sacrificing their intrinsic mechanical properties, is demonstrated using electron beam irradiation. Such treatment leads to physically improved roughness as well as chemically introduced hydrophilic oxygen-containing functional groups on the surface of carbon fibers that are essential for assuring an efficient stress transfer from carbon fibers to a polymer matrix.

Catalytic dehydrocoupling of 1,1-dihydrotetraphenylsilole (1) with various inorganic hydrides produces electroluminescent polysiloles (2) in high yield. The polymerization yield and molecular weight increase in the order LiB[CH(CH3)C2H5]3H < NaB[CH(CH3)C2H5]3H < KB[CH(CH3)C2H5]3H. The polymerization yields are almost equal for Na[H2Al(OCH2CH2OCH3)2], KB[CH(CH3)C2H5]3H, and LiB(C2H5)3H, but the molecular weights increase in the order Na[H2Al(OCH2CH2OCH3)2] < KB[CH(CH3)C2H5]3H < LiB(C2H5)3H. The polysiloles emit green light at 520 nm and are electroluminescent at 520 nm.
