Refractive index and density matching are essential for optical measurements of neutrally buoyant liquid–liquid flows. In this study, we proposed a design experiments (DoE) to develop refractive systems, including objective setting, candidates screening, sampling fitting, detailed process. Candidates screening criteria based on the ranges aqueous organic phases were used. Using DoE, system with...

The unusual mixed valence CuII/CuI coordination polymer based on 2,5-bis(pyridine-2-yl)-1,3,4-thiadiazole [CuI3CuIIL2(SCN)5]n has been prepared by reaction between the thiadiazole ligand (L), CuCl2·2H2O and KSCN in H2O/CH3CN solution. title complex characterized using single-crystal X-ray diffraction, spectroscopic measurements, as well Hirshfeld surface analysis. TGA analysis magnetic measurem...

Slot-die coating is highly promising for scaled deposition of metal halide perovskite thin films. However, the power conversion efficiencies (PCEs) slot-die-prepared solar cells (PSCs) still lag behind their spin-casted counterparts. To resolve this issue, crystal size and quality slot-die-coated methylammonium lead triiodide (MAPbI3) films are dramatically improved via additive engineering usi...

Despite the great advancement of experimental tools and theoretical models, a quantitative characterization of the microscopic structures of ion aggregates and its associated water hydrogen-bonding networks still remains a challenging problem. In this paper, a newly-invented mathematical method called persistent homology is introduced, for the first time, to quantitatively analyze the intrinsic...

The potentiometric titration (PT) method has been applied for the first time to investigate stability of l-ascorbic acid (H2Asc) and determine its degradation products in aqueous solutions. presented electrochemical procedures can be considered a fast, simple inexpensive way control H2Asc regular analytical practice as well chemical pharmaceutical industries. Experimental data modeling suggest ...
