Pathomorphological Changes in Poultry Pasteurellios, Pullorosis and Colibacteriosis Diseases

The organism of chicken infected with individual pathogens exhibits relatively simple patho-anatomical modifications in the presence of two or three separate bacterial pathogens. Because it is highly challenging to differentiate between mixed bacterial infections based just on clinical symptoms, pathologoanatomical examination and distinction are preferred. These disorders will be accurately diagnosed promptly and without delay if the pathologo-anatomical investigations are properly examined, and preventive measures will be consistently applied

Graphite-protected CsPbBr3 perovskite photoanodes functionalised with water oxidation catalyst for oxygen evolution in water

Metal-halide perovskites have been widely investigated in the photovoltaic sector due to their promising optoelectronic properties and inexpensive fabrication techniques based on solution processing. Here we report the development of inorganic CsPbBr3-based photoanodes for direct photoelectrochemical oxygen evolution from aqueous electrolytes. We use a commercial thermal graphite sheet and a mesoporous carbon scaffold to encapsulate CsPbBr3 as an inexpensive and efficient protection strategy. We achieve a record stability of 30 h in aqueous electrolyte under constant simulated solar illumination, with currents above 2 mA cm−2 at 1.23 VRHE. We further demonstrate the versatility of our approach by grafting a molecular Ir-based water oxidation catalyst on the electrolyte-facing surface of the sealing graphite sheet, which cathodically shifts the onset potential of the composite photoanode due to accelerated charge transfer. These results suggest an efficient route to develop stable halide perovskite based electrodes for photoelectrochemical solar fuel generation

Fabrication and characterization of c-Si/porous-Si/CdS/ZnxCd1-xo heterojunctions for applications in nanostructured solar cells

Abstract Solar cells based on c-Si/porous-Si/CdS/ZnₓCd₁₋ₓO heterojunctions were synthesized by depositing CdS films on c-Si/porous-Si (PS) substrates by electrochemical deposition (ED). PS layers with systematically varied pore diameter (8÷45 nm) and were fabricated on p-type c-Si wafers using electrochemical etching. The window layers of ZnₓCd₁₋ₓO with several Zn concentrations(x=0.2; 0.4; 0.5 and 0.6) were also deposited on the CdS buffer layers by ED. The photoelectrical properties of heterojunctions were studied as functions of PS pore size and Zn content in ZnₓCd₁₋ₓO. The optimal pore size and Zn contents were found to be 10 nm and x=0.6, respectively. These yielded a solar cell sample exhibiting an efficiency of 9.9%, the maximum observed in this study
