Crystallisation of a tris-p-carboxylatocalix[4]arene from various pyridine derivatives leads, in some cases, to further self-assembly into triply helical nanotubes, demonstrating the degree of tolerance of the structure motif towards the introduction of alkyl groups around the aromatic ring of the guest template.
New yellow-green emitting materials using bis(dipyrrinato)zinc complex moiety were synthesized by substituting phenyl group and 1- or 2-positioned naphthalene group. Bis[5-(1-naphthalenyl)-dipyrrinato]zinc complex (Zn(1-NaPN)2) substituted at position 1 of naphthalene group showed about 10 times stronger photoluminesc…
We report on the improvement of electrical quality of (100)-Ge/high-k-dielectric interfaces by introducing thin Pt top layers on the dielectric and subsequent oxidative treatments or using a Pt-deposition process with inherent oxidative components. Here, deposition of thin physical vapor deposition-Pt layers, combined…
Continuous advance in the potential of fabrication and utilization of nanostructures for different applications requires an adequate tool for such structures’ analysis and characterization. Investigation of light scattered by nanostructures by means of computer simulation seems to be a reliable tool for investigation…
Synthetic elastin hydrogels are useful tissue engineering scaffolds because they present cell binding sequences and display physical performance similar to that of human elastic tissue. Small pores and a low porosity can limit cellular penetration into elastin scaffolds. To overcome this problem, glycosaminoglycans we…
Virial coefficients up to B 8 are calculated for the soft-sphere model, with exponents n = 12, 9 and 6. It is demonstrated that for n = 12, the virial series truncated at B 8 describes well the equation of state (EOS) of the fluid phase up to the freezing density, while for n = 9 and 6 the series departs from the corr…
We report soft x-ray reflectivity measurements near the Si L2,3 absorption edge for Si-rich silicon nitride thin film obtained by Hg-sensitized photochemical vapor deposition. We demonstrate that the precise analysis of optical index profile derived over extended energy region gives compositional details of the film.…
The structural and magnetic properties of 1.8 nm Co particles dispersed in a Mn matrix by co-depositing pre-formed mass-selected Co clusters with an atomic vapour of Mn onto a common substrate have been studied by using EXAFS (extended x-ray absorption fine structure), XMCD (x-ray magnetic circular dichroism), magneto…
The excitation functions for $^{7}\mathrm{Li}+^{28}\mathrm{Si}$ quasielastic scattering at ${150}^{\ifmmode^\circ\else\textdegree\fi{}}$ and ${170}^{\ifmmode^\circ\else\textdegree\fi{}}$ have been measured at sub- and near-barrier energies (0.6 to 1.3 ${\mathrm{V}}_{\mathrm{B}}$) and the corresponding barrier distribu…

Before the active form of a Pt drug reaches its major pharmacological target in the cell nucleus, the Pt complex has to accumulate in cells, and during its transportation into cells and inside cells, it reacts with various biomolecules. Satraplatin is the first orally administered Pt drug under active clinical investi…
A quantitative structure-fluorescence property relationship (QSPR) analysis of a large 288-membered library based on a single fluorescent BODIPY scaffold is presented for the first time. BODIPY is a versatile fluorescent scaffold with outstanding photophysical properties. Absorption (λabs ) and fluorescence emission (…
A simple and engineering friendly one-step process has been used to prepare zirconium titanium mixed oxide beads with porosity on multiple length scales. In this facile synthesis, the bead diameter and the macroporosity can be conveniently controlled through minor alterations in the synthesis conditions. The precursor…
Targeted delivery of proteins into the hippocampus has not yet been achieved. Here, we show that systemic administration of the β-galactosidase, fused to a 43-amino-acid peptide derived from rabies virus glycoprotein (RVG), results in targeted delivery of the fusion protein into the hippocampal neurons. This approach…
The biopharmaceutical profile of a compound depends directly on the dissociation constants of its acidic and basic groups. We estimate these constants using kernel ridge regression and graph kernels. The performance of our approach is similar to that of a semi-empirical model (Tehan et al, QSAR & Comb. Sci. 21(5): 457…
The boronic acid group is an important recognition moiety for sensor design. Herein, we report a series of isoquinolinylboronic acids that have extraordinarily high affinities for diol-containing compounds at physiological pH. In addition, 5- and 8-isoquinolinylboronic acids also showed fairly high binding affinities…
The determination of viscosity from the attenuation of capillary waves was first suggested by Stokes more than a century ago. At the time, it was not practical to measure the attenuation of surface waves with the requisite precision to render the method useful. We describe a noncontact method for measuring the wavelen…
Bis(1,2-4 triazin-3-yl)pyridines “BTPs” represent a new class of N-donor extracting agents that separate trivalent actinides and lanthanides from nuclear waste solutions with high An/Ln separation factors. We report here QM calculations on the effect of Rpara–BTP substituents on the protonation and complexation energi…
We present a simple setup that combines immersion lithography with a Lloyd's mirror interferometer. Aiming for smaller structure sizes, we have replaced the usual Lloyd's interferometer by a triangular Littrow prism with one metal-coated side, which acts as a mirror. Because of the higher refractive index of the prism…
This Brief Report introduces a short-range order parameter, called the generalized multicomponent short-range order (GM-SRO) parameter. The application to Monte Carlo simulations is described for higher order solid solutions. The results show the ability to create atomic-scale systems with a particular subset of the G…
