Copper(I) Thiocyanate (CuSCN) Hole-Transport Layers Processed from Aqueous Precursor Solutions and Their Application in Thin-Film Transistors and Highly Efficient Organic and Organometal Halide Perovskite Solar Cells

This study reports the development of copper(I) thiocyanate (CuSCN) hole-transport layers (HTLs) processed from aqueous ammonia as a novel alternative to conventional n-alkyl sulfide solvents. Wide bandgap (3.4–3.9 eV) and ultrathin (3–5 nm) layers of CuSCN are formed when the aqueous CuSCN–ammine complex solution is spin-cast in air and annealed at 100 °C. X-ray photoelectron spectroscopy confirms the high compositional purity of the formed CuSCN layers, while the high-resolution valence band spectra agree with first-principles calculations. Study of the hole-transport properties using field-effect transistor measurements reveals that the aqueous-processed CuSCN layers exhibit a fivefold higher hole mobility than films processed from diethyl sulfide solutions with the maximum values approaching 0.1 cm2 V−1 s−1. A further interesting characteristic is the low surface roughness of the resulting CuSCN layers, which in the case of solar cells helps to planarize the indium tin oxide anode. Organic bulk heterojunction and planar organometal halide perovskite solar cells based on aqueous-processed CuSCN HTLs yield power conversion efficiency of 10.7% and 17.5%, respectively. Importantly, aqueous-processed CuSCN-based cells consistently outperform devices based on poly(3,4-ethylenedioxythiophene) polystyrene sulfonate HTLs. This is the first report on CuSCN films and devices processed via an aqueous-based synthetic route that is compatible with high-throughput manufacturing and paves the way for further developments

Immunoprotectivity of attenuated turkey poxvirus in turkey poults and broiler chicks

In Nigeria, fowl pox vaccine is used in all categories of poultry. However there has been reports of outbreak of turkey pox virus in poults previously vaccinated with fowl pox vaccine. Pox Lesion from poults was excised for isolation of virus and viral propagation in chorioallantoid membrane. Turkey pox virus were isolated from the infected turkeys and confirmed by infecting susceptible turkeys with the isolate to reproduce the disease. Persistence of both turkey poults and broiler chickens to challenge after vaccination with attenuated turkey poxvirus was confirmed.

Prevalence of Bovine Fasciolosis in Bauchi State, Nigeria

A total of 1600 faecal samples were collected from live cattle in five local government areas (LGAs) of Bauchi state, Nigeria, for a period of 12 months and analyzed using formol-ether sedimentation technique for the presence of Fasciola eggs. The study revealed an overall prevalence of 76.9 % in the state. Dass local government area (LGA) had the highest prevalence (83.6 %), while Ningi LGA had the least (74.2 %). Adult cattle had higher prevalence (64.1 %) than the young ones (35.9 %). This was statistically significant (
