For folate-receptor-targeted anticancer therapy, docetaxel (DTX) nanoparticles (NPs) were produced employing polylactide-co-glycolide-polyethylene glycol-folate (PLGA-PEG-FOL) conjugate. The FOL-conjugated di-block copolymer was synthesized by coupling the PLGA-PEG-NH(2) di-block copolymer with an activated folic acid…
Cotton is one of the most important raw materials for textile and clothing production. Compared with some synthetic polymer fibers, the main drawback of cotton fibers is its poor mechanical properties and its high flammability, and therefore it can not be used for special textiles. Cotton fabrics treated with modern f…
Aurivillius oxides family has attracted great interest in the last years due to their promising electrical properties as high temperature piezoelectric materials. Piezoelectric materials that could operate in extreme conditions of use (elevated temperatures and hostile environments) could be of particular interest for…
The effect of particle size on the electrochemical performance of electrical double-layer capacitors (EDLCs) has been studied using carbon derived from silicon carbide powders with to grains at temperatures from 800 to . For the same synthesis temperature, similar pore texture and microstructure of carbide-derived car…
Voltammetric dealloying of bimetallic platinum-copper (Pt-Cu) alloys has been shown to be an effective strategy to modify the surface electrocatalytic reactivity of Pt bimetallic nanoparticles (S. Koh and P. Strasser, J. Am. Chem. Soc., 2007, 129, 12624). Using cyclic voltammetry and structural XRD studies, we systema…
Abstract Detonation nanodiamond (DN) was discovered in 1963, but for several reasons was known only among a small number of scientists until the turn of the century. The most serious cause was the fact that primary nanocarbon particles formed by the "bottom-up method" are in general covalently bound together under hig…
Nb, Ta, and Zr are the favorable nontoxic and allergy-free alloying elements suitable for use in titanium alloys for biomedical applications. Low-rigidity titanium alloys composed of nontoxic and allergy-free elements are receiving considerable attention. The advantage of low-rigidity titanium alloys in the healing of…
In this study, electrical, thermal and mechanical properties of multi-walled carbon nanotubes (CNTs) reinforced Epon 862 epoxy have been evaluated. Firstly, 0.1, 0.2, 0.3, and 0.4 wt% CNT were infused into epoxy through a high intensity ultrasonic liquid processor and then mixed with EpiCure curing agent W using a hig…
We describe the design of new ligands made by coupling commercially available poly(ethylene glycol) methyl ether (mPEG, HO-PEG-OCH3) and thioctic acid (TA) via a stable amide bond to form TA-PEG-OCH3 molecules. The ligands were obtained by a simple transformation of the hydroxyl group on the mPEG into an amine group,…
The synthesis and spectroscopic characterization of a series of new blue-emitting silafluorene–fluorene copolymers is described. The polymers are synthesized using kinetically controlled hydrosilylation copolymerization of 1,1-dihydridosilafluorene with a series of 9-substituted 2,7-diethynylfluorenes. The polymers co…
It is commonly observed that the “traditional” aqueous solution route to prepare CdTe nanocrystals (NCs) using thiol ligands as capping reagents is usually very time-consuming and the luminescent properties are poor in the deep red to near infrared (NIR) emission window. Herein, we present an ultrafast and facile aque…
The simultaneous sputter deposition of gold and silver onto ionic liquids formed bimetallic alloy nanoparticles, which exhibited composition-sensitive surface plasmon resonance, the peak wavelength being red-shifted with an increase in the surface area of the gold foil targets sputtered.
In this work, we report the first application of water-soluble fluorescent Ag nanoclusters in fluorescent sensors. The fluorescence of poly(methacrylic acid) (PMAA)-templated Ag nanoclusters was found to be quenched effectively by Cu2+, but not when other common metal ions were present. By virtue of the specific respo…
A highly hydrothermally stable microporous network material has been developed that can be applied in energy-efficient molecular sieving. The material was synthesized by employing organically bridged monomers in acid-catalysed sol–gel hydrolysis and condensation, and is composed of covalently bonded organic and inorga…
ZnO nanocrystals are presented as an electron injection layer for red, green, and blue light-emitting diodes (LEDs) based on core–shell CdSe/ZnS quantum dots (QDs). The deposition of ZnO nanocrystals from isopropanol permits fabricating multilayer QD-LEDs that include both hole and electron transport layers by simple…
In this Highlight article we will describe the current impact of nanoscale materials (nanoparticles and carbon nanotubes) in liquid crystal nanocomposites on the improvement of LC display (LCD) applications, an industry currently worth more than $60 billion per year. First tendencies clearly demonstrate the potential…
Time-dependent Hartree-Fock and Møller-Plesset second-order calculations have been used to unravel the relationships between structure and first hyperpolarizability in spiropyran/merocyanine couples and therefore to design efficient second-order nonlinear optical switching compounds. Large first hyperpolarizabilities…
Natural fiber reinforced renewable resource based laminated composites were prepared from biodegradable poly(lactic acid) (PLA) and untreated or surface-treated pineapple leaf fibers (PALF) by compression molding using the film stacking method. The objective of this study was to determine the effects of surface treatm…
Phase-field modelling is still a young discipline in condensed-matter physics, which established itself for the class of systems that can be characterised by domains of different phases separated by a distinct interface. Driven out of equilibrium, their dynamics result in the evolution of those interfaces which might…
The precepts of green chemistry have been spreading since the mid-1990s, concomitant with advances in nanomaterial synthesis. Recently these two communities have begun to significantly converge. Nanomaterial synthesis groups are developing greener, more sustainable production methods, while nanoparticle application gr…
