For developing functional biomaterials, an understanding of the biological response at material surfaces is of key importance. In particular, surface chemistry, roughness and cell type influence this response. Many previous reports in the literature have involved the study of single cell types and their adhesion to su…
The non-classical KP(6)Mo(18)O(73) heteropolyanion has been studied by the density functional theory (DFT) method, and the calculated geometry compares well with the experimental one. In fully oxidized [KP(6)Mo(18)O(73)](7-) state, the d(xy)-orbitals centered at eight "belt" Mo sites in the lower part of the "basket"…
Gold nanorods (GNRs) are strongly absorbing at near-infrared (NIR) frequencies and can be employed as multifunctional agents for biological imaging and theragnostics. GNRs can support nonlinear optical microscopies based on two-photon-excited luminescence and can enhance the contrast of biomedical imaging modalities s…
Improved thermal cycling durability of a solid oxide fuel cell (SOFC) using a -based electrolyte was studied by inserting a thin (SSC55) cathode interlayer with a submicron-sized convex. The thin SSC55 interlayer was prepared on a SDC20-LSGM9182 bilayer film by pulsed layer deposition. The resulting maximum power dens…
Tablet manufacturing has been changed by the introduction of the direct‐compression process and high‐speed machines. These two developments have increased the demands on the functionality of excipients in terms of flow and compression properties. Direct compression is the preferred method for the preparation of tablet…
Two types of conjugated polymers were prepared with the goal to blend them with rod-like CdSe nanocrystals. The polymers of the first type were synthesized through copolymerization of 3-octylthiophene and 3-methylene-ethylcarboxylate-thiophene to give polythiophene with solubilizing alkyl groups and methylene ester fu…
Reliability in phase-change memory (PCM) devices is mainly related to the metastable nature of the amorphous phase, affected by crystallization and structural relaxation (SR) processes. More recently, low-frequency noise has attracted interest both as a valuable investigation tool of the microscopic properties of the…
Nematic liquid crystals often host topological defects in the form of disclination lines. Because of the elastic anisotropy intrinsic to nematics, the tight distortions of the molecular ordering around the defect lines couple to the mean nematic orientation inducing deformations on length scales easily observed in con…
The new erbium(III) and ytterbium(III) monoporphyrinate complexes were synthesized and hybridized into silica xerogel frameworks though the coordination of 5-(N,N-bis(3-propyl)ureyl-1,10-phenanthroline to the lanthanide ions. The complexes are eight-coordinate with strong emissions in solution in the near-infrared reg…
Photolysis of porphyrin-ruthenium(IV) dichlorate complexes with visible light results in homolytic cleavage of the O-Cl bond in the chlorates to form trans-dioxoruthenium(VI) species bearing either sterically encumbered or unencumbered porphyrin ligands.
An "artificial frustule" was prepared through a single-templating approach, where the self-assembled architecture undergoes a transition from cocoons with pore channels parallel to the surface, to hollow spheres with perpendicular pore channels.
The potential for expanding the variety of enzymic methods for siloxane bond formation is explored. Three enzymes, Rhizopus oryzae lipase (ROL), lysozyme and phytase are reported to catalyse the condensation of the model compound, trimethylsilanol, formed in situ from trimethylethoxysilane, to produce hexamethyldisilo…
First-principles calculations represent a potent tool for screening metal hydride mixtures that can reversibly store hydrogen. A number of promising new hydride systems with high hydrogen capacity and favorable thermodynamics have been predicted this way. An important limitation of these studies, however, is the assum…
A new family of hexametallic [Mn(III)₆] Single-Molecule Magnets with general formula [Mn₆O₂(R-sao)₆(X)₂(MeOH)₄₋₆] (R= H, Me, Et or Ph; X = O₂PHPh or O₂P(Ph)₂) have been synthesised and characterised. The molecules are new members of the [Mn₆] family of SMMs in which the carboxylate ligands have been replaced with phen…
During atmospheric pressure plasma treatment, reactive species generated in the plasma diffuse through a boundary gas layer which is adsorbed at the material surface. Many of the reactive species become inactivated before reaching the surface due to their short lifetime. The efficiency of plasma treatment can be highl…
Nanoporous gold was used as a high specific surface material to describe the water radiolysis in the vicinity of metal surfaces. Porous gold monoliths were prepared by electrolytic dissolution of silver in Au-Ag alloys and characterized by small angle neutron scattering. The hydroxyl radical production under gamma irr…
Different lanthanide chelates have been simultaneously embedded in a silica matrix yielding bright dual-mode lanthanide doped nanospheres which are uniform in size distribution, tunable, photostable, and leakage free. Depending on the chelate combination, two color emission with a single light source or tunable emissi…
Chalcogenides are compounds formed predominately from one or more of the chalcogen elements; sulphur, selenium and tellurium. Although first studied over fifty years ago, interest in chalcogenide glasses has, over the past few years, increased significantly as glasses, crystals and alloys find new life in a wide range…
We investigated transport properties of organic heterointerfaces formed by single-crystals of two organic donor-acceptor molecules, tetramethyltetraselenafulvalene and 7,7,8,8-tetracyanoquinodimethane (TCNQ). Whereas the individual crystals have unmeasurably high resistance, the interface exhibits a resistivity of few…
Nanotechnology is expected to open new avenues to fight and prevent disease using atomic scale tailoring of materials. Among the most promising nanomaterials with antibacterial properties are metallic nanoparticles, which exhibit increased chemical activity due to their large surface to volume ratios and crystallograp…
