Today, neurodegenerative diseases are very common among people. As a result, researchers are investigating methods for treatment of these diseases. One therapeutic approach is differentiating stem cells into neural cells to replace damaged areas of the brain. Cell attachment is the first, necessary step for the proces…
On-line monitoring of crystal size in the crystallization process is crucial to many pharmaceutical and fine-chemical industrial applications. In this paper, a novel method is proposed for the on-line monitoring of the cooling crystallization process of L-glutamic acid (LGA) using electrical impedance spectroscopy (EI…
Abstract Carbon thin films, having a combination of unique physical and chemical properties, exhibit an interesting biocompatibility and biological response to living entities. Here, the carbon films are developed in the morphology form of nano-domains with nanoscale inter-domain separations, tuned by plasma condition…
Atomic adsorptions of N, C and O on silicene and molecular adsorptions of N2 and CO on silicene have been investigated using the density functional theory (DFT) calculations. For the atomic adsorptions, we find that the N atom has the most stable adsorption with a higher adsorption energy of 8.207 eV. For the molecula…
Abstract Magnetic conducting nanoparticles with reactive functional groups are attractive materials for applications in electromagnetic interference shielding, magneto‐optical storage, biomedical sensing, gas and humidity sensors, flexible electronics etc. The objective of this work was to prepare carboxyl functionali…
ABSTRACT Poly(methyl methacrylate‐co‐butyl methacrylate) [P(MMA‐co‐BMA)] nanoparticles were synthesized via emulsion polymerization, and incorporated into natural rubber (NR) by latex compounding. Monodispersed, core‐shell P(MMA‐co‐BMA)/casein nanoparticles (abbreviated as PMBMA‐CA) were produced with casein (CA) as s…
Switching luminescence of lanthanide-based molecules through an external electric field is considered as a promising approach toward novel functional molecule-based devices. Classic routes use casted films and liquid electrolyte as media for redox reactions. Such protocol, even if efficient, is relatively hard to turn…
The conformation of homodendrimers and amphiphilic dendrimers in various solvents is studied using classical density functional theory (DFT), in which the excluded-volume effects are treated explicitly. For homodendrimers in an athermal solvent, DFT results predict a remarkable fold-back behavior for the outer generat…
This work demonstrates dual emission "OFF-ON-OFF" switching at visible and UV wavelengths of a carbazole functionalized β-diketone (LH) by a simple change of a europium(III) ion (Eu(3+)) concentration in the submicromolar concentration range. In the presence of 0.25 equiv of Eu(3+) (5 μM), LH forms a luminescent 4:1 c…
Abstract In this work, BaTi 1− x − y O 3 : x Er/ y Yb (BTO: x Er/ y Yb, x = 0, y = 0; x = 0.005, y = 0.005; x = 0.01, y = 0.005; x = 0.01, y = 0.01; x = 0.015, y = 0.01) ceramics were prepared using a conventional solid-reaction method to investigate the relation between the Curie transition and up-conversion photolum…
The objective of this study was to determine properties of pulp and paper produced from Citrus aurantium widely available in The Mediterranean region by applying Soda- Anthraquinon (AQ) method. Chemical compositions of C. aurantium in addition to basic properties of papers were evaluated. The results showed that C. au…
We investigate the modulation of optical phonons in semiconductor crystals by a surface acoustic wave (SAW) propagating on the crystal surface. The SAW fields induce changes on the order of ${10}^{\ensuremath{-}3}$ in the time-averaged Raman peak intensity by optical phonons in Si and GaN crystals. The SAW-induced mod…
We demonstrate continuous-wave four-wave mixing to probe the acoustic vibrations of gold nanorods in aqueous solution. The nonlinear optical response of gold nanorods, resonantly enhanced by electrostriction coupling to the acoustic vibration modes, shows an extensional vibration which combines an expansion along the…
Films based on thermoplastic corn starch (TPS) and talc nanoparticles were developed by melt mixing and thermo‐compression. Films structure, optical and barrier properties, as well as thermal stability and water sorption behavior were studied. TPS structure resulted homogeneous and smooth. Talc laminar morphology and…
The application of dendrimers for biological and medical purposes is highly dependent on the type of surface group in relation to cytotoxicity. Since amine terminated PAMAM dendrimers have been shown to have toxic properties and thereby limited applications in the medical field, the discovery of a new nontoxic surface…
The charge transfer dynamics at interfaces are fundamental to know the mechanism of photovoltaic processes. The internal potential in solar cell devices depends on the basic processes of photovoltaic effect such as charge carrier generation, separation, transport, recombination, etc. Here we report the direct observat…
With remarkably interesting surface activities, two-dimensional Janus materials arouse intensive interests recently in many fields. We demonstrate by molecular dynamic simulations that hydrofluorinated Janus graphene (J-GN) can self-assemble into Janus nanoscroll (J-NS) at room temperature. The van der Waals (vdW) int…
BACKGROUND: Lymphatic filariasis caused by Wuchereria bancrofti, Brugia malayi and B. timori, is a debilitating disease with an adverse social and economic impact. The infection remains unabated in spite of treatment with existing antifilarial drugs diethylcarbamazine (DEC) and ivermectin which are chiefly microfilari…
Two hybrid materials based on decavanadates (DMAPH)6[V10O28]·H2O, (1) and (DMAPH)6[V10O28]·16H2O, (2) (where DMAPH = 4-dimethylaminopyridinium) were obtained by reactions under mild conditions at T = 294 and 283 K, respectively. These compounds are pseudopolymorphs, which crystallize in monoclinic P 2 1 / n and tricli…
To enhance the electrochemical energy storage performance of supercapacitors (SCs), the current researches are general directed towards the cathode materials. However, the anode materials are relatively less studied. In the present work, Fe 3 O 4 -MoO 2 (FO-MO) hybrid nano thin film directly grown on Ti substrate is i…
