Understanding the microscopic origin of physical properties is fundamental to the study of glasses. In the present study, unique trends were observed in structural and dynamical properties in lead-borate [xPbO:(1-x)B2O3] glasses upon increasing the modifier. Properties driven by short-range structural changes like, glass transition temperature (Tg) and elastic modulii exhibit a broad maxima around...
TiO2 nanofibers were synthesized by incorporating sol-gel and electrospinning techniques using polyvinyl pyrrolidone and titanium tetraisopropoxide sol-gel as precursor. The as prepared composite fibres were of ∼300 nm average diameter. Calcination of these composite fibres at 500° C in air resulted in pure anatase titania nanofibres, of 84 nm mean diameter with smooth surfaces, without contamination...
