Thermoluminescence from the UV-Irradiated Solution of Triphenylmethane at Low Temperature

Structural and UV-irradiated thermoluminescence studies of ZnS: Cu nanoparticles synthesized by wet chemical route method

Pure and copper doped ZnS nanoparticles in powder form were prepared by wet chemical route method by using thioglycerol as a capping agent. The XRD studies indicate that the samples are cubic in nature. The thermoluminescence (TL) behavior of pure and copper doped ZnS has been studied for fixed 10 min UV exposure time; TL glow curve shows a single peak at 165.1°C and 184.3°C temperature respect...

Low-temperature dephasing in irradiated metallic wires

Solution-based synthesis of GeTe octahedra at low temperature.

GeTe octahedra were prepared by reaction of equimolar amounts of GeCl2·dioxane and Te(SiEt3)2 in oleylamine, whereas a slight excess of the Te precursor yielded GeTe octahedra decorated with elemental Te nanowires, which can be removed by washing with TOP. The mechanism of the GeTe formation is strongly influenced by the solvent. The expected elimination of Et3SiCl (dehalosilylation) only occur...

the effect of traffic density on the accident externality from driving the case study of tehran

در این پژوهش به بررسی اثر افزایش ترافیک بر روی تعداد تصادفات پرداخته شده است. به این منظور 30 تقاطع در شهر تهران بطور تصادفی انتخاب گردید و تعداد تصادفات ماهیانه در این تقاطعات در طول سالهای 89-90 از سازمان کنترل ترافیک شهر تهران استخراج گردید و با استفاده از مدل داده های تابلویی و نرم افزار eviews مدل خطی و درجه دوم تخمین زده شد و در نهایت این نتیجه حاصل شد که تقاطعات پر ترافیک تر تعداد تصادفا...

Liquid-like behavior of UV-irradiated interstellar ice analog at low temperatures

Interstellar ice is believed to be a cradle of complex organic compounds, commonly found within icy comets and interstellar clouds, in association with ultraviolet (UV) irradiation and subsequent warming. We found that UV-irradiated amorphous ices composed of H2O, CH3OH, and NH3 and of pure H2O behave like liquids over the temperature ranges of 65 to 150 kelvin and 50 to 140 kelvin, respectivel...
