Ba(0.5)Sr(0.5)Co(0.8)Fe(0.2)O(3-δ) (BSCF) with the cubic perovskite structure is known to be metastable at low temperature under an oxidizing atmosphere. Here, the thermal and chemical expansion of BSCF were studied by in situ high temperature powder X-ray diffraction and thermo-gravimetrical analysis (TGA) in partial…
We present a method for the polymerization of low molecular weight hydrogelators to form polymers with unique structures. Carbazole-protected amino acids are shown to form hydrogels by self-assembly into fibrous structures. We show that is possible to directly electropolymerize the hydrogels. This results in the forma…
Lanthanide( iii )-based multi-colored hybrid materials showing potential in WLEDs and self-referencing luminescent thermometers.
The SO 2 -induced atmospheric corrosion of some magnesium-aluminum (Mg-Al) alloys, including Mg alloy AZ91D, and commercially pure Mg (CP Mg) was investigated using well-controlled laboratory exposures and included real-time measurements of SO 2 deposition. The influence of SO 2 concentration, alloy composition, humid…
Doxorubicin-loaded nanogels with multiresponsive properties are prepared using hyperbranched polyglycerol as a biocompatible scaffold. The nanogels are synthesized in a single step combining free-radical polymerization and a mild nanoprecipitation technique. The nanogels respond to different biological stimuli such as…
In this paper we study a two-dimensional system of charged colloidal particles using Brownian dynamics simulations. We determine the phase diagram and investigate the dynamics of this system in the density regime where hexatic and solid phases are stable. We find that the dynamics in these phases is heterogeneous by m…
β-Phenylethynyl (PE) porphyrins exhibited unique photophysical properties and solvatochromic behavior due to ICT from the porphyrin core to PE moieties. Further, Zn( ii ) porphyrins were utilized for anion sensing.
We have demonstrated Cu 2−x Ag x CdSnSe 4 nanocrystals can result in decreases in the lattice thermal conductivity while increasing the Seebeck coefficient. A ZT up to 0.8 was obtained when x is 0.3.
Much attention has been paid to utilizing polydopamine (PDA) as the stationary phase in open-tubular capillary electrochromatography (OT-CEC) owing to its diverse properties, such as strong adhesion to various surfaces, latent reactivity toward amine and thiol groups and metal ion chelating/redox activities. In this s…
The influences of experimental parameters in the process of CdSe QD deposition via a capping ligand-induced self-assembly method on the QD loading and the performance of the resultant cell devices have been systematically investigated and optimized.
This work presents the synthesis and characterization of soluble and conducting polyaniline PANI-PIA according to chemical polymerization route. This polymerization pathway leads to the formation of poly(itaconic acid) doped polyaniline salts, which are highly soluble in a number of mixtures between organic common pol…
A protective-group-free synthetic route to multiply functionalized dendrimers is presented.
A novel biosensor for silver( i ) ion detection based on nanoporous gold and duplex-like DNA scaffolds with anionic intercalator.
The thermodynamic stability of lanthanide cobaltites is also a function of their existing oxygen non-stoichiometry.
Codelivery of nitric oxide (NO) and drugs based on a single nanocarrier is a promising therapeutic strategy. Here, we report a one-step nanoprecipitation method to generate nanoparticles that possess simultaneous NO-donating and doxorubicin releasing properties. S-Nitroso polysilsesquioxane acts like an avid "drug spo…
The light-driven reversible dimerization of a coumarin-functionalized organic–inorganic hybrid polyoxometalate anion and the resulting changes in their aggregation and redox-behaviour are reported.
Multiferroic oxides have been received much attention due to that these materials exhibit multiple ferroic order parameters (e.g., electric polarization in ferroelectrics, magnetization in ferromagnetics, or spontaneous strain in ferroelastics) simultaneously in the same phase in a certain temperature range, which off…
In this work, we propose a method for constructing silver nanoparticles (AgNPs) on mesoporous silica nanospheres (MSNs) by a DNA-templated process. By in situ formation, the gatekeeper can be easily modulated to meet different degrees of glutathione (GSH) stimuli for location-specific drug release.
Vinyl-terminated hyperbranched poly(amido amine)s is obtained by Michael addition polymerization of 4-(aminomethyl)piperidine (AMPD) with a double molar N,N-cystaminebis(acrylamide) (BAC). Then an amphiphilic hyperbranched poly(BAC2-AMPD1)-PEG is produced via converting the vinyl groups to amines followed by PEGylatio…
We explored the effects of changing the separation distance on the charge transfer interactions between luminescent QD and proximal dopamine (in QD-dopamine assemblies), and the ensuing photoluminescence (PL) quenching. The separation distance was controlled using a tunable size bridge between the QD and dopamine via…
