Conducting mesoporous TiO2 is rapidly gaining importance for green energy applications. To optimise performance, its porosity and crystallinity must be carefully fine-tuned. To this end, we have performed a detailed study on the temperature dependence of TiO2 crystallisation in mesoporous films. Crystal nucleation and growth of initially amorphous TiO2 derived by hydrolytic sol-gel chemistry is...

dentin hypersensitivity (dh) is a relatively common painful condition among dental problems. although many studies have been performed regarding the diagnosis and treatment of dh, dental practitioners are still confused about the definite diagnosis and treatment.the use of lasers as a treatment for dentin hypersensitivity was first introduced in 1985. laser treatment in dentin hypersensitivity ...

A 40-year old woman was visited at our clinic with a history of palpable purpura appearing after alexandrite laser (Apogee 5500 Alex, 15mm spot shot, 755 nm wave length, 18 j/cm2 fluence) hair removal. The skin lesions were located bilaterally on the lower extremity (Figure1). Other physical examinations were unremarkable. The patient had no history of taking medications, underlying systemic di...
