A fast, linker free, one step strategy for in situ preparation of graphene oxide/Ag nanoparticle (GO-AgNP) nano-composites was proposed by reducing AgNO3 with chemiluminescent reagent luminol in the presence of GO. The nano-composites were characterized by transmission electron microscopy, energy-dispersive spectrosco…
Two linear tetranuclear lanthanide complexes of general formula [Ln(4)(L)(2)(C(6)H(5)COO)(12)(MeOH)(4)], where HL = 2,6-bis((furan-2-ylmethylimino)methyl)-4-methylphenol, () and Ln(III) = Dy(III) (1) and Gd(III) (2), have been synthesized and characterized. The crystal structural analysis demonstrates that two Schiff-…
Triple-shape memory polymers are developed by blending and crosslinking two semicrystalline polymers (poly(cyclooctene), PCO, and polyethylene, PE) towards creating two pronounced segregated crystalline domains within a covalently crosslinked network. The key thermo-mechanical properties of a series of a polyalkenamer…
The present study demonstrates a novel approach by which titanium foils coated with MnO2 nanowires can be processed into a high surface area electrode for rechargeable energy storage applications. A detailed study has been performed to elucidate how surface morphology and redox reaction behaviors underlying these elec…

CoFe(2)O(4) nanotubes have been directly fabricated by single-capillary spinneret electrospinning. The external diameter of the CoFe(2)O(4) nanotubes ranges from 60 nm to 160 nm. The morphology and structure characterizations show that individual CoFe(2)O(4) nanotubes are made of CoFe(2)O(4) nanocrystals stacking alon…
Here we report the synthesis, electrochemical properties, and optical properties of five novel π-conjugated alternating copolymers based on the BODIPY core. These polymers were synthesized via the Sonogashira polymerization reaction and contain BODIPY units alternating with comonomers such as 9,9-bis(2-ethylhexyl)-9H-…
The well-defined metal NPs@POM–GNS tri-component nanohybrids were synthesized by a green, facile, one-pot method. The obtained nanohybrids exhibited exciting electrocatalytic activity for methanol and formic acid oxidation.
For the very first time, highly efficient synthesis of DNA-peptide hybrids to scaffold self-assembled nanostructures is described. Oligonucleotide conjugation to the diphenylalanine dipeptide triggers a morphological transition from fibrillar to vesicular structures which may potentially be used as delivery vehicles,…
The programs hosted in the Bilbao Crystallographic Server (http://www.cryst.ehu.es) are briefly explained along with worked examples on various cases related to different fields of applications. It is our aim to have this text acting as a primer on the various usage of the crystallographic tools in conjunction with ea…
Ammonia borane (NH(3)BH(3), AB) is a unique molecular crystal containing an intriguingly high density of hydrogen. In the past several years, AB has received extensive attention as a promising hydrogen storage medium. Several strategies have been successfully developed for promoting H(2) release and for suppressing th…
The ability to control the morphologies and spectral properties of organic low-dimensional nanomaterials is of paramount importance. The research reported herein demonstrates a template-free approach to tailored morphological and optical properties for a novel class of pseudoisocyanine (PIC)-based fluorescent organic…
This review summarizes the recent developments in fluorescent conjugated polyelectrolytes (CPEs) in bioimaging. The CPEs discussed include linear-, hyperbranched-, and polyhedral oligomeric silsesquioxanes (POSS)-based derivatives. Originating from their special optical properties, good photostability, low cytotoxicit…
A functionalized six-membered cyclic carbonate monomer containing a protected thiol group, 2-(2,4-dinitrophenylthio)ethyl-5-methyl-2-oxo-1,3-dioxane-5-carboxylate (MTC), was prepared. Ring-opening polymerization (ROP) of MTC and L-lactide (LA) initiated by monohydroxyl poly(ethylene glycol) (mPEG) was successfully per…
Carbonaceous nanospheres with silver nanoparticles (CNs-Ag) composites were prepared by a facile and low cost method. Silver nanoparticles were successfully loaded onto the surface of carbonaceous nanospheres, which were examined by X-ray diffraction, UV-vis spectra, transmission electron microscopy, energy dispersive…
Three novel ring-like compounds formulated as [Ln(Phtfac)(3)(NITpPy)](2) (Ln(III) = Gd 1, Tb 2, Dy 3; HPhtfac = 4,4,4-trifluoro-1-phenylbutane-1,3-dione; NITpPy = 2-(4-pyridyl)-4,4,5,5-tetramethyl-4,5-dihydro-1H-imidazolyl-1-oxyl-3-oxide) were synthesized and structurally and magnetically characterized. Three compound…
Poly(vinyl alcohol) cast gels (PVA cast gels) were prepared at different gelation temperatures, Tgel, and the swelling ratio and mechanical properties were characterized by the equilibrium weight measurement, a uniaxial loading test, a tearing force measurement, and a cyclic compression test at room temperature. The r…
The use of Room Temperature Ionic Liquid (RTIL) electrolytes promises to improve the energy density of Electrochemical Capacitors (ECs) by allowing for operation at higher voltages.

Enantioselective recognition of amino acids was achieved by using a highly ordered chiral assembly of achiral porphyrin on a chiral molecular gel. Exceptionally high enantioselectivity was observed for histidine derivatives by monitoring the CD patterns and fluorescence quenching, K(SV) (l): 26.3 × 10(3) M(-1); K(SV)(…
Commercially available hydroxyapatite (HAp) nanoparticles were used as sole emulsifiers to produce stable methyl myristate-in-water and soybean oil-in-water high internal phase emulsions (HIPEs).
