The immobilization of α-chymotrypsin on the surface of boron silicate glass microspheres is conducted via the technique of multilayer adsorption of polyelectrolytes. It is shown that the enzyme is adsorbed on both positively and negatively charged surfaces and its activity is partially preserved relative to that in so…
Non-ordered organic-inorganic mesoporous hybrid materials with basic sites have been synthesized following a fluoride-catalysed sol-gel process at neutral pH and low temperatures that avoids the use of structural directing agents (SDAs). Proton sponges have been used as the organic builder of the hybrids, while the in…
In this paper we present an adaptive algorithm for calculating the isotropic Compton profile (ICP) for any type of Gaussian basis set. The ICP is a measure of the momentum density of electrons and it can be obtained from inelastic X-ray scattering experiments employing synchrotron radiation. We have performed calculat…
We have investigated the photophysical properties of two types of triphyrins with focus on the fused-moiety effects by performing various spectroscopic measurements and theoretical calculations.
Dense thin-film La 0.6 Sr 0.4 Co 0.2 Fe 0.8 O 3-δ (LSCF6428) electrodes of thickness 450 nm were symmetrically deposited onto either side of gadolinium doped ceria (CGO) electrolyte pellets by spray pyrolysis. Three film electrodes were fabricated with three different average grain sizes; 285, 370 and 535 nm. The grai…
We studied the adsorption and reactivity of SO(2) on clean and oxygen precovered Pd(100) with high resolution X-ray photoelectron spectroscopy and density functional calculations. Upon adsorption at 120 K two different SO(2) species were detected, which were identified as upright-standing and flat-lying molecules by c…
Experiments described in this work employ Raman spectroscopy and electrochemical impedance spectroscopy (EIS) to characterize the properties of a YSZ electrolyte in situ at 715 °C and under electrochemical potential control. The YSZ itself is the electrolyte in a functioning, electrolyte supported SOFC membrane electr…
In this work, a cinnamate derivative has been synthesized and infiltrated into a silica colloidal crystal template together with methyl methacrylate and ethylene glycol dimethylacrylate to construct cinnamate-based inverse-opal films. The resulting cinnamate-based photonic films can undergo reversible [2 + 2] photo-cy…
In this study, the effect of two important parameters have been evaluated for pressure driven liquid flows in microchannel in laminar regime by analytical modeling, followed by experimental measurement. These parameters are wettability conditions of microchannel surfaces and aspect ratio of rectangular microchannels.…
Spherical cap gold nanocavity arrays with internal diameters of 240, 430, 600 and 820 nm were fabricated on smooth gold films using nanosphere lithography with electrochemical metal deposition. Each array was prepared to the same normalized film thickness to diameter ratios, t(N), of 0.8 ± 0.04. Selective modification…
Amphiphilic anthracene derivatives showed solvent-polarity-dependent fluorescence. Monomer emission and aggregation-induced emission (AIE) were observed in polar and non-polar organic solvents, respectively. AIE became predominant in aqueous solution in the case of hexafluorophosphate as a counter anion.
A-site substituted cerium metavanadates, Ce1−xCaxVO3,were synthesised by solid-state reactions from single-phase powders of the corresponding orthovanadates. All metavanadate samples were found to exhibit either an orthorhombic and/or monoclinic phase of space groupPnma (62) with a = 5.5067 (4), b = 7.7904 (5) and c =…
In light of tissue engineering, development of a functional and controllable scaffold which can promote cell proliferation and differentiation is crucial. In this study, we introduce a controllable collection method of the electrospinning process for regularly-distributed and uniaxially oriented nanofiber scaffold and…
Photochemical generation of a reactive carbene-modified gold nanoparticle (AuNP) in the presence of micro-diamond monocrystalline powder leads to a robust covalent diamond-AuNP hybrid material.
Employing density functional theory (DFT) based calculations, we perform a computational investigation to unravel the intricate spin-crossover transitions that have been observed (Niel et al., Angew. Chem., Int. Ed., 2003, 42, 3760) in cyanide-based bimetallic coordination polymers, [Fe(pmd)-(H2O){M(CN)2}2]·H2O (M = A…
Poly(styrene-co-divinylbenzene) microspheres of narrow size distribution were prepared by (2-hydroxypropyl)cellulose-stabilized dispersion copolymerization of styrene and divinylbenzene in a 2-methoxyethanol/ethanol mixture under continuous addition of divinylbenzene. The copolymerization was initiated with dibenzoyl…
A W-band single-crystal EPR study has been performed on a molecular cluster comprising 19 iron(III) ions bridged by oxo- hydroxide ions, Fe(19), in order to investigate magnetic nanosystems with a behavior in between the one of Magnetic NanoParticles (MNP) and that of Single Molecule Magnets (SMM). The Fe(19) has a di…
Dynamic impact response of Inconel 718 alloy is studied at temperatures ranging from −150 to 550°C and strain rates in the range of 1000 to 5000 s−1 using a compressive split Hopkinson pressure bar. It is found that the flow stress increases with increasing strain rate, but decreases with increasing temperature. The h…
The current study aimed at designing cationic and biodegradable biomaterials with improved biological functionality. We report the enzymatic synthesis, characterization and preliminary biological assessment of a series of novel functionalized poly(ester-co-carbonate)s, namely [poly(ADMC-co-CL)]s containing tertiary am…
