Abstract Different 2D and quasi-2D perovskite materials have demonstrated significant improvements in the device stability compared to 3D perovskites due their increased hydrophobicity suppressed ion migration. However, fundamental investigations of these been scarce consequently detailed understanding processes responsible for experimental phenomena are often lacking despite huge interest mate...

‎‎‎In this paper‎, ‎we develop multi-step methods to solve a class of two-dimensional nonlinear Volterra integral equations (2D-NVIEs) of the first kind‎. ‎Here‎, ‎we convert a 2D-NVIE of the first kind to a one-dimensional linear VIE of the first kind and then we solve the resulted equation numerically by multi-step methods‎. ‎We also verify convergence and error analysis of the method‎. ‎At t...

In this work, we introduce a novel method for solving two-dimensional fuzzy Fredholm integral equations of the second kind (2D-FFIE-2). We use new representation of parametric form of fuzzy numbers and convert a two-dimensional fuzzy Fredholm integral equation to system of two-dimensional Fredholm integral equations of the second kind in crisp case. We can use Adomian decomposition method for n...

The paper is related to an interesting case of revision X-ray crystal structure with a lack experimental data. Complexes V4OSe8I6·X (X = I2 or 3,5-dimethylpyrazole) O-centered complex molecules [V4O(μ-Se2)4I4(μ-I)2] were synthesized in our group. In the further search for new relative compounds V-Se-I-O system, we obtained several crystals different structures, including “V4OSe6I3”, incredibly ...

Jazz is a new general-purpose toolkit that supports applications using zooming object-oriented 2D graphics. It is built entirely in Java using Java2D, and thus runs on all platforms that support Java 2. It supports zooming, internal cameras, and lenses in a similar style to Pad++, but does so in a general purpose manner without a specific focus on zooming. Jazz is primarily a "scenegraph" for 2...
