In this paper we focus upon the electron injection dynamics in complete nanocrystalline titanium dioxide dye-sensitized solar cells (DSSCs) employing the ruthenium bipyridyl sensitizer dye N719. Electron injection dynamics and quantum yields are studied by time-resolved single photon counting, and the results are correlated with device performance. In typical DSSC devices, electron injection ki...
objective(s) sildenafil citrate is a new drug and has special properties that bring about nitric oxide effects on vascular smooth muscle. the aim of this study was to assess the effects of ovarian stimulation and sildenafil citrate injection on pinopode expression in mice. materials and methods thirty adult female mice were randomly divided into three groups: control, hyperstimulated and hypers...
In this paper, we introduce RF electron gun of Iranian Light Source Facility (ILSF) pre-injection system. Design, fabrication and low-power microwave tests results of the prototype RF electron gun have been described in detail. This paper also explains the tuning procedure of the prototype RF electron gun to the desired resonant frequency. The outcomes of this project brighten the path to the f...
Irradiation of biological matter triggers a cascade of secondary particles that interact with their surroundings, resulting in damage. Low-energy electrons are one of the main secondary species and electron-phonon interaction plays a fundamental role in their dynamics. We have developed a method to capture the electron-phonon inelastic energy exchange in real time and have used it to inject ele...
The generation of high quality electron beams in a laser wakefield accelerator (LWFA) is generally thought to require phased injection of an ultrashort electron bunch. However, simulations have shown that longer bunch, unphased injection may also produce high quality, short electron bunches if the injection energy is properly chosen. The process involves pruning of electrons that move into defo...
