Activated ester polymers, pioneered by Ferruti and Ringsdorf in the 1970s, are attractive polymeric materials because they can easily be converted into functional polymers by reacting with amine nucleophiles. In the present study, methyl salicylate acrylate, salicyl acrylate, and tert-butyl salicylate acrylate monomer…
The purpose of this study is to investigate the chemical interaction between carboxyl-functionalized single-walled carbon nanotubes (SWNTs) and multi-walled carbon nanotubes (MWNTs) with in situ chemically polymerized polypyrrole (PPy) films (approximately 8 nm) by resonance Raman spectroscopy. The composites (SWNT/PP…
The role of charge transfer (CT) contribution to the surface-enhanced Raman scattering (SERS) effect from the view of Albrecht's “A” and Herzberg-Teller (HT) contributions is presented. The basic understanding of Albrecht's “A,” “B,” and “C” terms and the HT selection rule are explained to understand the SERS-CT mecha…
First-principles calculations were performed to study structural, electronic and hydride diffusion properties of BaTiO 3 oxyhydride. In agreement with experiment ( Nat. Mater. 2012, 11, 507 and J. Am. Chem. Soc. 2012, 134, 8782), we find that the incoming H species occupy the anion vacancy sites left by oxygen, formin…
Polyamide 6/SiO2 (PA6/SiO2) nanocomposites with varying amounts of SiO2 were prepared by using a novel sol-gel technique. These nanocomposites were formed in situ by hydrolysis and through the condensation of tetraethoxysilane (TEOS) using formic acid with a small amount of water as the solvent for PA6. Observations o…
Abstract Die Proteinadsorption gilt als der wichtigste Faktor der Wechselwirkung zwischen polymeren Biomaterialien und Körperflüssigkeiten oder ‐gewebe. Die Haupteinflussfaktoren auf die Proteinadsorption sind wasservermittelte hydrophobe und Hydratationskräfte sowie elektrostatische Wechselwirkungen. Eine systematisc…
In recent trend, the most used fiber reinforced composite is the glass fiber composite. The glass-fiber composites have high strength and mechanical properties but it is costlier than sisal and jute fiber. Though the availability of the sisal and jute fiber is more, it cannot be used for high strength applications. A…
Digestive ripening, a postsynthetic treatment of colloidal nanoparticles, is a versatile method to produce monodisperse nanoparticles and to prepare various bimetallic nanostructures. The mechanism of this process is largely unknown. Herein, we present a systematic study conducted using Au nanoparticles prepared by a…
Multiferroic materials, which synchronously exhibit magnetism and ferroelectricity, are promising multifunctional materials, especially for spin electronic applications. The magnetoelectric effect has been observed in many multiferroic materials and couples magnetism and ferroelectricity. However, until now, the coupl…
A novel class of alkynylgold(III) complexes of the dianionic ligands derived from 2,6-bis(benzimidazol-2'-yl)pyridine (H2bzimpy) derivatives has been synthesized and characterized. The structure of one of the complexes has also been determined by X-ray crystallography. Electronic absorption studies showed low-energy a…
Inhibition of mGAT1, the most abundant GABA transporter in the brain, enhances GABA signaling and alleviates symptoms of CNS disorders such as epilepsy assumed to be associated with low GABA levels. We have now developed a potent and subtype selective photoswitchable inhibitor of this transporter, which for the first…
Herein, we report the synthesis of guanidinium bis-porphyrin tweezers 1 and fullerene carboxylate 3, their assembly into a novel supramolecular 1@3 electron donor-acceptor hybrid, and its characterization. In solution, the binding constant affording 1@3 is exceptionally high. 1@3, which features a highly confined topo…
Abstract Silver nanoparticles (AgNPs)‐loaded calcium alginate beads embedded in gelatin scaffolds were developed to sustain and maintain the release of silver (Ag + ) ions over an extended time period. The UV irradiation technique was used to reduce Ag + ions in alginate solution to AgNPs. The average sizes of AgNPs r…
In order to investigate whether the incorporation of multi-walled carbon nanotubes (MWCNTs) and rectorite (REC) could improve and extend the properties of nanofibrous mats, poly(lactic acid)/MWCNTs/REC ternary composite nanofibrous mats were fabricated via an electrospinning technique. The composite mats still kept a…
Objectives: Cost effective and eco-friendly technique for green synthesis of silver nanoparticles from the methanolic extract of Costus pictus leaf and characterization of synthesized silver nanoparticles was carried out in this study. Methods: Synthesis of silver nanoparticles of Insulin plant (Costus pictus) leaves…
Hydrophobicity of PLA nanoparticles makes them a good substrate for macrophageal and reticulo-endothelial system uptake. Long-circulating properties can be imparted to these particles by coating them with hydrophilic stabilizers. Surface-modified PLA nanoparticles loaded with anti-cancer agent temozolomide were fabric…
Research is currently being carried out to develop high-performance solid-state supercapacitors (SCs) with high energy density. One effective method to improve the energy density of the solid-state SC devices is enlarging their operating voltage. Organic electrolytes and asymmetric structure have been employed in supe…
To develop edible films having controlled release properties for multiple bioactive compounds, hydrophobicity and morphology of zein films were modified by blending zein with oleic (C18:1)Δ⁹, linoleic (C18:2)Δ(9,12), or lauric (C₁₂) acids in the presence of lecithin. The blend zein films showed 2-8.5- and 1.6-2.9-fold…
In the fields of nanoparticle synthesis and application, the control of the particle size, shape and composition is crucial. The tuning of these different parameters can be performed during the synthesis, but often, additional selection steps to improve the purity of a given nanoparticles’ population are necessary. Th…
Abstract A new heterometallo‐supramolecular polymer with alternating Cu I and Fe II ions (polyCuFe) was synthesized by simple 0.5:0.5:1 complexation of Cu I and Fe II salts with an unsymmetrical ditopic ligand ( L1 ) bearing phenanthroline and terpyridine moieties as the metal coordination sites. Selective complexatio…
