Separation of enantiomers of a chiral compound is one of the most interesting and challenging tasks because of their identical physical and chemical properties. Magnetic materials possessing chiral functionality on their surface can not only exhibit magnetic properties but also recognize chirality. Fe3O4@ZrO2 core–she…
Imbedment of cobalt particles into a zeolite crystal was developed using conventional Co/SiO2 as the precursor of the zeolite via simple hydrothermal method. The obtained cobalt-imbedded zeolite catalyst with imbedded structure and confined reaction environment showed a remarkable catalytic performance for the direct…
Pt@NH2-MIL-125(Ti), containing ultrafine Pt nanoparticles in its cages, was successfully synthesized by a double solvent method followed by photoreduction, and their use as a photocathode material for photoelectrochemical hydrogen production was explored.
Increasing the penetration of drugs within solid tumors can be accomplished through multiple ultrasound-mediated mechanisms. The application of ultrasound can directly change the structure or physiology of tissues or can induce changes in a drug or vehicle in order to enhance delivery and efficacy. With each ultrasoni…
Ir(III) metal complexes with general formula [(C^N)2Ir(P^SiO)], where (C^N)H is 2-phenylisoquinoline (1), 2-phenylpyridine (2) or 2-(2,4-difluorophenyl)pyridine (3), and (P^SiO)H is an organosilanolate ancillary chelate with either diphenylsilyl (a) or dimethylsilyl (b) substituent, were synthesized, among which the s…
We studied the competitive chloride/MPS adsorption on Cu(100) by means of in situ STM. MPS (mercaptopropane sulfonic acid) spontaneously forms on the bare metallic copper surface by dissociative adsorption of SPS (bis-(3-sulfopropyl)disulfide). MPS self-assembles on Cu(100) giving rise to the formation of a c(2 × 6)-M…
Cardiac tissue regeneration is guided by stem cells and their microenvironment. It has been recently described that both cardiac stem/primitive cells and extracellular matrix (ECM) change in pathological conditions. This study describes the method for the production of ECM typical of adult human heart in the normal an…
Two new cadmium(II) coordination polymers (CPs), {[Cd(BTG)(bpy)(H2O)]·0.5glycol·H2O}n (1) and {[Cd6(BTB)4(bpy)4.5(glycol)]·9H2O}n (2) (H2BTG = 1,2,3-benzene tricarboxylic acid 2-(2-hydroxy-ethyl) ester, an ester of 1,2,3-benzenetricarboxylic acid and glycol; H3BTB = 1,2,3-benzenetricarboxylic acid), have been synthesi…
Heteroleptic tris-cyclometalated Ir(III) complexes supported by the o-carboranyl-pyridine (CBpy) as a novel C^N chelating ligand were synthesized and characterized. While the CBpy ligand contributes to the electronic stabilization of complexes, their photophysical properties are dominated by 2-arylpyridine ligands.
The reaction of imidazole with hydroiodic acid leads to three products crystallizing as ionic salts; [C3N2H5+][I−], [C3N2H5+]2[I42−] and [C3N2H3I2+][I−]. All the analogs were characterized by single-crystal X-ray diffraction, while the first two were additionally studied by calorimetric, dilatometric, dielectric and p…
Hierarchical porous carbon spheres are prepared by the carbonization of a D201 anion-exchange resin. These carbon spheres are characterized by X-ray diffraction, Raman spectroscopy, nitrogen adsorption–desorption and electron microscopy. The lithium ion storage capacity of these carbon spheres is evaluated by galvanos…
The efficient host materials containing carbazole moieties linked to the backbone of polysiloxane through a phenyl bridge have been synthesized and characterized. They exhibit good film forming ability, high thermal decomposition temperatures and suitable glass transition temperatures, so as to form stable amorphous s…
Viscosity changes during the crystallization of a shoshonitic lava from the Vulcanello peninsula (Aeolian Islands, southern Tyrrhenian Sea, Italy) were measured by use of a electromagnetic rotational viscometer under Ni-NiO buffered conditions at temperatures ranging from 1539 K to 1381 K. Results showed an increase i…
Heteropolyacids (HPAs) supported on magnetic nanoparticles (MNPs) have been prepared by a simple acid–base interaction between functionalized magnetic nanoparticles and HPAs. The surface of the catalyst had been modified by organic groups to protect the catalytic sites from destruction by water. The hybrid SiO2-MNP-HP…
The specific π-π interactions between curved and planar structures, which are different from the general π-π interactions between planar arenes, have generated great attention due to their brand-new, unique, and fascinating photoelectric properties. Herein, the curved-planar (C-P) π-π interactions between corannulene,…
A series of glutarimide derivatives which has two carbonyl coordination sites for intramolecular pentacoordination at silicon with a X(1+n)SiC(3-n)O moiety have been synthesised and characterized. The substituent (leaving group) effects on the Si-O bond exchange between the two coordination sites (resembling a pendulu…
Three new cadmium coordination polymers with formula {[Cd(tdc)(bpe)(H2O)]·2H2O}n (1), [Cd(tdc)(bpp)]n (2), and [Cd(Htdc)2(bipy)]n (3) have been synthesized by hydrothermal reactions of cadmium acetate dihydrate and 3,4-thiophenedicarboxylic acid (H2tdc) in the presence of the corresponding bis(pyridyl) ancillary ligan…
We demonstrate application of a commercial nanoporous polyvinyl chloride (PVC)/silica separator in an all-vanadium redox flow battery (VRB) as a low-cost alternative to expensive Nafion membranes. This hydrophilic separator is composed of silica particles enmeshed in a PVC matrix that creates unique porous structures.…
We report a facile and template-free soft chemical approach that employs a low-temperature calcination treatment to synthesize a new class of materials comprising self-arranged hollow mesoporous Co3O4 and Co3O4–carbon nanotube composites. Each hollow particle is formed by a double-layered nanowall with a thickness of…
Various carriers are being advanced for anti-cancer therapy, which can protect drugs and ferry them to the target site. However, little understanding exists regarding the effect of molecular structure on anti-cancer drug delivery efficiency. To fill this knowledge gap, we take poly(lactic acid) (PLA), poly(lactide-co-…
