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. RTIL electrolytes 1-ethyl-3-methylimidazolium tetrafluoroborate (EMImBF(4)), 1-ethyl-3-methylimidazolium dicyanamide (EMImN(CN)(2)), 1,2-…
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). The droplet size in the Pickering inverse HIPEs (i-HIPEs) could be adjusted within a certain range by tailoring the energy…
We demonstrate the synthesis of two triptycene-based microporous poly(benzimidazole) networks through condensation of triptycene-hexone with dialdehyde in refluxing glacial acetic acid containing ammonium acetate. The benzimidazole-linkage in the resulting polymers is confirmed by Fourier transform infrared and solid-…
In this study, we develop an efficient method for multiple DNA detection by exploring silver nanoclusters (AgNCs)-graphene oxide (GO) nanohybrid materials. Because of the extraordinarily high quenching efficiency of GO, the ssDNA-AgNCs probe exhibits minimal background fluorescence, while strong emission is observed w…
Superhydrophobic surface with high solid/liquid adhesion is of great fundamental and technological importance. However, the fabrication of adhesive superhydrophobic polymer surfaces with high stability is rare, which limits the utilization of such surfaces in harsh environments. This paper illustrates a simple electro…
Both structure-directing effect and synergistic-directing effect of PW(9)O(34) fragments result in two poly(polyoxotungstate)s (poly(POT)s) of the Ni(24)-based tetramer with largest transition metal atoms among ring-shaped poly(POT) tetramers and the Ni(40)-based poly(POT) octamer with the highest number of Ni ions am…
The Cr(II) binding sites of an experimentally realised hydrazine linked hydrogen storage material have been studied computationally using density functional theory. Both the experimentally determined rise in H(2) binding enthalpy upon alteration of the ancillary ligand from bis[(trimethylsilyl)methyl] to hydride, and…
A rare μ(4)-OH centred square Dy(4) aggregate displays a field enhanced thermally activated mechanism with 3-fold increase in the single-molecule magnetic relaxation barrier upon application of an optimal field.
An ethoxy-bridged dinuclear indium catalyst was used for the ring opening polymerization of the cyclic ester β-butyrolactone to form the biodegradable polyester poly(hydroxybutyrate) (PHB). The catalyst shows remarkable activity and control during polymerization, allowing for formation of diblock polymers. Addition of…
