A major challenge for outdoor uses of methylammonium lead halide (MAPbX3) solar cells is the poor durability of the perovskite film under humidity. This instability is due to limitations of the dipping or spin coating process in producing MAPbX3 films through a direct reaction between PbI2 and methylammonium iodide (MAI) in an organic solvent. In this study, we devised an eco-friendly and cost-effective method to fabricate MAPbX3 films using an aqueous solution of Pb(NO3)2 and MAI vapour. I

This study aims to investigate how nematodes’ communities variables such as diversity, sex and feeding structure alter in different 5 layers of sediment deep profile of the river bed. Our studies found for the first time that nematodes’ communities not only stay on 10 cm first layers but they can contribute until 50 cm deep in the sediment profile of the river bed.

The aim of this study was to obtain and characterise thin metal organic frameworks layers supported on various metallic structured carriers such as FeCrAl plates and woven gauzes and NiCr foams. The thin layers of the metal organic frameworks were fabricated by in situ solvothermal deposition, optimised by the selection of metal precursor and the layering/washing order.

Financial disclosure plays a very important role for organizations and individuals when participating in the stock market. For commercial banks, adequate and timely disclosure of financial information will increase transparency and affect not only the behaviour of investors in the market but also the customer’s decision to deposit and using bank’s services.

Despite the increasing importance of species richness of blowfly fauna and their environmental, medical, and agricultural importance in the world they are poorly studied in Turkey. This study was carried out in 2014 and 2015 to determine the distribution, abundance, and species richness of blowfly species in Isparta Province of Turkey. A total of 15 species (10 from Calliphoridae, 4 from Polleniidae, and 1 from Rhiniidae) were identified from 13 different localities.

The optimum growth time was acquired to be 11 hours. Thereby such obtained electrode exhibited the maximum HER activity with onset over the potential of 220 mV versus reversible hydrogen electrode (RHE), and the Tafel slope of 66 mV per decade (mV/dec). Conclusion: Our results suggest a good technique for the research of high-efficient HER electrocatalyst based on atomicthickness layered materials.

A set of catalysts having gold nanoparticles deposited on γ-Al2O3 (Au/γ-Al2O3) with lowest effective amount of gold content were prepared by successive impregnation and hydrogen reduction method. The structural features of prepared catalysts were analysed by X-ray diffraction (XRD), N2 physisorption, scanning electron microscopy (SEM), and Fourier transform infrared (FTIR). The catalytic activity was evaluated for the reduction of an organic pollutant 4-nitrophenol (4NP) to 4-aminophenol (4AP) by spectrophotometric analysis.
