Novel star-shaped hole transporting materials with a triazine unit have been synthesized. When the new Triazine-Th-OMeTPA was used as a hole transporting material in perovskite solar cells, the power conversion efficiency reached 12.51% under AM 1.5 G (100 mW cm(-2)) illumination, showing competitive photovoltaic performance with the widely used spiro-OMeTAD based solar cell (13.45%).

Abstract Scatter-hoarding animals decide their food hoarding location by assessing quality and pilfering risk. Previous studies have proposed two non-mutually exclusive hypotheses; the optimal density model (ODM) habitat structure hypothesis (HSH). The ODM proposes that utilize low cache to protect valuable caches transporting far from sources. HSH predation risk in open areas. Here, we investi...

The fact that embryos can be obtained in vitro undermines the role of the oviduct. However, it has been demonstrated that when in vitro produced bovine zygotes are cultured in the oviduct of sheep, cattle or mice the embryo quality is improved compared to the embryos produced in vitro. Thus the oviduct is not simply a passive organ required only for transporting the embryo to the uterus but als...

Abstract—Woolcool is an eco–friendly type of packaging, made of 100% pure sheep’s wool, hygienically sealed in recyclable food– grade wrap. Due to its complex physical and chemical composition, wool can also help control humidity and reduce condensation. Given these properties, the potential of wool to be used as packaging liners for the transport of meat is of interest. The present study asses...

rotary atomizers are commonly used in spray dryers to atomize feed. one destructive effect of wheel rotation is the creation of a vacuum inside the wheel that conducts hot air from the chamber into the wheel and can lead to atomizer blockage and an explosion. the present work determined the air-pumping characteristics of a rotary atomizer with a 50 mm wheel diameter. the vacuum pressure and pow...

as the multi-service network of choice, it is plausible consider its use for transporting demanding multimedia traffic with high bandwidth and low delay and packet loss requirements. Emerging technologies for quality of service such as Differentiated Services and MPLS can be used for premium quality traffic. In this paper we present a Traffic Engineering and Control System that starts from agre...

This paper evaluates the performance of the federal standard 2.4 kbps MELP vocoder when used over ATM networks that are subject to cell loss. It begins by addressing the sensitivity of MELP to random deletion of frames; it quantifies the extent to which the quality of the reconstructed speech is affected by two factors – the rate at which frames are lost and the burstiness of that loss process....

In recent years, technologies like Ultra Wideband (UWB) were developed that can be used to boost the data rate of wireless nodes to a new level. The higher data rate makes wireless networks capable of transporting multimedia content for real time applications like In Flight Entertainment (IFE), surveillance applications, or structural health monitoring. In this paper we measure and simulate the...
