Phase formation and transformation of 3D inorganic halide perovskites CsPbI3 CsPbI2Br were investigated by in-situ X-ray diffraction (XRD) in nitrogen or air from 30 °C up to 320 °C. Thin films obtained spin-coating a liquid solution salt precursors dissolved DMSO under normal conditions. XRD data analysis, using the Le Bail method, evidenced for first time, our knowledge, spontaneous crystalli...

The reaction of CH₃NH₂ with O₂ on the singlet potential energy surfaces (PES) was carried out using the B3LYP, CCSD(T) and G3B3 theoretical approaches along with 6-311++G(3df,3pd) basis set. The suggested mechanism for the title reaction consists of one pre-reactive complex. From the pre-reactive complex, nine types of products, CH2NH+H2O2, CH3NH+OOH,...

Objective: To determine the sub-specialization preferences among masters of medicine in ophthalmology in selected universities in Eastern Africa and barriers to sub-specialization. Design: This was a cross-sectional study. Method: An analysis of data obtained from 35 masters of medicine students in ophthalmology from six universities/teaching hospitals in three countries within Eastern Africa w...

Fully solution-processed, large-area, electrical double-layer transistors (EDLTs) are presented by employing lead sulfide (PbS) colloidal quantum dots (CQDs) as active channels and Ti3C2Tx MXene contacts (including gate, source, drain). The successfully patterned standard photolithography plasma-etch techniques integrated with CQD films. large surface area of film is effectively gated ionic gel...
