Light soaking and hysteresis phenomena can reveal the bulk and interfacial polarization effects on photovoltaic processes in perovskite solar cells. The frequency-dependent impedance and time-dependent photoluminescence measurements indicate that bulk and interfacial polarizations are internally coupled in developing…
Since the report of the first diketopyrrolopyrrole (DPP)-based polymer semiconductor, such polymers have received considerable attention as a promising candidate for high-performance polymer semiconductors in organic thin-film transistors (OTFTs). This Progress Report summarizes the advances in the molecular design of…
Current hyaluronic acid (HA) hydrogel systems often cause cytotoxicity to encapsulated cells and lack the adhesive property required for effective localization of transplanted cells in vivo. In addition, the injection of hydrogel into certain organs (e.g., liver, heart) induces tissue damage and hemorrhage. In this st…
The success of perovskite solar cells has sparked enormous excitement in the photovoltaic community not only because of unexpectedly high efficiencies but also because of the future potential ascribed to such crystalline absorber materials. Far from being exhaustively studied in terms of solid-state properties, these…
A novel homologous series of liquid crystalline (LC) behaviors of Schieff’s bases: RO-C 6 H 4 -CH=CH-COO-C 6 H 4 -N=CH-C 6 H 4 -OC 2 H 5 have been synthesized and studied with a view to understand and establish the effect of molecular structure on LC properties of a novel substances. The members of a novel series are…
An oral press-coated tablet was prepared by using direct compression method to achieve the predetermined lag time. This press-coated tablet containing montelukast sodium in the inner core was formulated with an outer barrier layer by different compositions of hydrophobic polymer ethylcellulose and hydrophilic polymer…
Snails are a kind of important aquatic products and dehydration is the main technique in production of snail meal. Apple snail (<em>Pomacea canaliculata</em>) dehydration meets both the demand for a fishmeal substitute in aquaculture and invasive species control in agriculture. In this study, we investigated the perce…
The accuracy of the special quasirandom structure (SQS) approach for modeling the structure and energetics of fluorite-structured oxide solid solutions with aliovalent cation substitutions is assessed in an ionic-pair potential study of urania and ceria based systems mixed with trivalent rare-earth ions. Mixing enthal…
Pelletized samples of polycrystalline zinc oxide ceramics doped with 2mol% MnO2 and 3mol% PbO were prepared by the conventional method of ceramic processing. The requisite composition was obtained by the direct mixing of constituent phases (DMCP) technique. Sintering was carried out at various temperatures ranging fro…
A series of linear covalent assemblies of dendrimers with conjugated backbones were synthesized by means of an iterative divergent and convergent method in which copper-catalyzed acetylene-azide cycloaddition reactions were used to form flexible linkages. UV-vis and fluorescence spectra indicate that dendrimeric assem…
30 vol.-% Ti3AlC2 particle reinforced Zn based (Zn–27 wt-% Al, denoted as ZA27) composites have been prepared via three different mechanically activated sintering technologies: pressureless sintering, hot pressing and combination of pressureless sintering and hot pressing (two-step sintering) technology. The relations…
Costs related to the decommissioning of nuclear power plants create a significant financial burden for nuclear power plant operators. This article discusses the various methodologies employed by selected European countries for financing of the liabilities related to the nuclear power plant decommissioning. The article…
Malva fiber was submitted to alkali treatments with NaOH aqueous solutions at different concentrations, times and temperatures. Fiber samples were analyzed before and after treatments to study their effects on crystallinity, thermal stability and morphology. The results showed that the crystallinity index and thermal…
UNLABELLED: Nanocomposite carboxymethyl cellulose films containing sinigrin (SNG) were prepared by stirring 2% (w/v) carboxymethyl cellulose (CMC) and 2% (w/v) glycerol (as a plasticizer) in distilled water with or without SNG (an antimicrobial precursor) as a 99% pure reagent (pSNG) or as a crude extract (cSNG). Thes…
The reliability of the circuits in the modern microelectronic devices remains, during last decades, one of the key topics in research and gains an attention for improving the promising candidates for conductors. Improvement of materials for such applications can be obtained by both electronic and compositional optimiz…
Supercritical fluid extraction and drying methods are well established in numerous applications for the synthesis and processing of porous materials.
