In spite of the impressive efficiencies reported for perovskite solar cells (PSCs), key aspects of their working principles, such as electron injection at the contacts or the suitability of the utilization of a specific scaffold layer, are not yet fully understood. Increasingly complex scaffolds attained by the sequential deposition of TiO2 and SiO2 mesoporous layers onto transparent conducting...

Dye-sensitized photosynthesis: Eosin Y (EY), a dye photosensitizer, works efficiently as a molecular photoelectrode by catalyzing the visible-light-driven electron-transfer reaction for efficient regeneration of NADH through a photosensitizer-electron relay dyad. Injection of the photosensitized electron resulted in highly accelerated regeneration of NADH, which can be used by glutamate dehydro...

Engineering aspects of electron and positron injection, storage and extraction in a damping ring of an injection complex are described. Symmetrical strip-line type kickers are used in quasi-traveling wave mode. A generator of a pair of negative and positive polarity pulses bases on two double pulse forming network (DPFN). Both DPFN are charged up to 50 kV using a common pulse transformer. Every...

The synchrotron radio maps of supernova remnants (SNRs) in uniform interstellar medium and interstellar magnetic field (ISMF) are analysed, allowing different ‘sensitivity’ of injection efficiency to the shock obliquity. The very-high energy γ-ray maps due to inverse Compton process are also synthesized. The properties of images in these different wavelength bands are compared, with particulr e...

A photocathode-based low-emittance femtosecondbunch electron source is developed in Osaka University to reveal the hidden dynamics of intricate molecular and atomic processes in materials through experimentation such as time-resolved pulse radiolysis or time-resolved electron diffraction. The transverse and longitudinal dynamics of femtosecond electron beam in the photocathode rf gun were studi...

In this research, the effects of oxygen injection during the induration process were studied in order to improve the quality specifications and increase the rate of production of the iron oxide pellets. Several experiments were carried out in palletizing pilot plant in different conditions of oxygen injection. The results suggested that if only the extra oxygen was injected into the furnace in ...

Laser wakefield acceleration of electrons holds great promise for producing ultracompact stages of GeV scale, high-quality electron beams for applications such as x-ray free electron lasers and high-energy colliders. Ultrahigh intensity laser pulses can be self-guided by relativistic plasma waves (the wake) over tens of vacuum diffraction lengths, to give >1  GeV energy in centimeter-scale low ...
