This work aims at the production of uniformly sized, equant shaped crystals using a direct nucleation control (DNC) strategy to help achieve enhanced manufacturability and bioavailability of the active pharmaceutical ingredients (API). A crystallizat...
CH3NH3PbI3 perovskite photovoltaic devices inserted with a polysilane layer were fabricated and characterized. A Decaphenylcyclopentasilane (DPPS) in chlorobenzene solution was spin-coated between the perovskite layer and the hole transport layer of...
High-resolution birefringence measurements and modulated differential scanning calorimetry have been carried out in order to investigate the critical behaviour near the isotropic to smectic-A, smectic-A to smectic-C* phase transitions associated with...
We report the fabrication and characterization of yttrium–aluminum–garnet (Er:YAG) and yttrium–scandium–aluminum–garnet (Er:YSAG) ceramics for the implementation of analysis as an active medium for 1500 nm lasing. High e...
In this work, we report the investigation of various experimental conditions and their influence on the polymorphism of 5-methyl-2-[(2-nitrophenyl)amino]-3-thiophen carbonitrile, commonly known as ROY. These conditions include an in-house-developed m...
Fabrication and characterization of CH3NH3PbI3 perovskite solar cell with the addition of copper (Cu2+), and potassium (K) or guanidinium (GA) was performed. The additive effects on the photovoltaic properties, morphologies, and crystalline structure...
Rapidly expanding and new applications of liquid crystal materials cover a wide range of technology products. A very incomplete list includes conventional and miniature high-resolution displays, AR/VR glasses, smart windows, dynamic lenses, tunable f...
Recently, a widely used method for recycling fly ash waste of coal collected from the electrostatic precipitators has been the synthesis of zeolites from this waste material [...]
Conversion efficiencies and stability of the perovskite solar cells were improved by adding a small amount of ethylammonium (EA) and rubidium (Rb) to the CH3NH3PbI3 compounds. Addition of ethylamine hydrobromide and rubidium iodide provided an increa...
Effects of addition of guanidinium [C(NH2)3; GA] on MAPbI3 perovskite solar cells fabricated at a high temperature of 190 °C in atmospheric air were investigated on the photovoltaic properties and first principles calculations. The addition of gu...
In this paper, the fabrication and characterization of CH3NH3PbI3 perovskite solar cells using decaphenylpentacyclosilane, copper phthalocyanine complex (CuPc) doped with tetracyanoquinodimethane (TCNQ), was performed. The effects of a carboxylic aci...
Heterocyclic ligands and their metallic complexes are biologically active materials [...]
The effects of maxed-valence states on electronic structures of europium (Eu)-incorporated CH(NH2)2PbI3 (FAPbI3) and CH3NH3PbI3 (MAPbI3) perovskite crystals were investigated by first-principles calculation. Partial replacements of europium ions into...
From the band calculation, the copper d-orbital band formed slightly above the valence band maximum would function as an acceptor level promoting the generation of carriers. In addition, the excitation processes from the p-orbital of iodine and the d...
Cyclometallated compounds, specifically cyclopalladates, have been synthesized for years. In this work, we describe a new family of compounds in which an iron core has been introduced in addition to Pd. This novel characteristic provides interesting...
Over the last decade, continuous manufacturing techniques have been increasingly used in the pharmaceutical manufacturing industry. However, despite the outstanding performance associated with the steady-state operation, continuous processes face com...
The quaternary compounds AI2BIICIVX4, where AI–Cu, Ag; BII–Zn, Cd, Hg; CIV–Si, Ge, Sn; and X–S, Se, Te, crystallize in non-centrosymmetric structures and may be of interest for nonlinear optics. Here, we present in detail isot...
In this work, an X-ray diffraction study of fluorine-functionalized thiosemicarbazone ligands and their corresponding cyclometallated compounds is discussed. The results are in agreement with previous characterization by IR spectroscopy, 1H and 19F N...
In this study, two novel spherical agglomeration processes based on membrane systems were successfully implemented to produce spherical agglomerates of benzoic acid crystals obtained via antisolvent crystallization. Two membrane configurations were c...
