Poly(3-hydroxybutyrate) (P3HB), its co-polymers with 3-hydroxyvalerate (HV) (PHBV8 and PHBV22), and their hydroxyapatite (HAp) containing composites (5 and 15%, w/w) were prepared by injection molding. PHBV bone plates with low valerate contents and 15% (w/w) HAp appear to have better mechanical properties than the ot…
The effect of PAMAM G3.5, PAMAM G4 and PAMAM-OH G4 dendrimers on human and bovine serum albumins has been studied by fluorescence spectroscopy at different pH and ionic strength. It has been shown that the interactions between dendrimers and proteins depend on pH and the efficiency of interactions can be regulated by…
Oblique orientated alpha-helices are highly specialised protein structural elements that penetrate membranes at a shallow angle and are used to promote membrane destabilisation by a number of protein classes. Here, the use of extended hydrophobic moment methodology shows that the amphibian extrudates, aurein 1.2 and c…
In this work, the dielectric constant of rubidium manganese hexacyanoferrate was observed in the ultraviolet, visible, and near-infrared regions using spectroscopic ellipsometry (SE). The SE data for ε drastically varied with the phase transition between the high-temperature and low-temperature phases, e.g., the gain…
Solid Oxide Fuel Cell (SOFC) developers are presently considering both internal and external reforming fuel cell designs. Generally, the endothermic reforming reaction and excess air through the cathode provide the cooling needed to remove waste heat from the fuel cell. Current information suggests that external refor…
Yttria-stabilized zirconia ͑YSZ͒ electrolyte disks with patterned platinum ͑Pt͒ electrodes having different three phase boundary ͑TPB͒ lengths ͑l TPB ͒, but the same electrode-electrolyte interface area, were deposited on one of the two faces using photomicrolithography.Platinum counter electrode was applied on the ot…
Novel micro-capsules (carbon nanotubosomes) have been fabricated by cross-linking shells of amine-functionalized multi-walled carbon nanotubes (MWNTs) produced by their adsorption on water-in-oil emulsion drops followed by an emulsion-inversion.
The step-wise assembly of the high nuclearity cluster, {[Ni(II)(H2O)5]6[Co(III)(tmphen)2]3[Fe(II)(CN)6]2}13+, is achieved by treating {[Co(tmphen)2]3[Fe(CN)6]2} with six equivalents of Ni(ClO4)2 in aqueous MeOH.
The majority of drug products are solid dosage forms, most of which contain the drug substance in the crystalline state. This review considers the forces responsible for crystal packing, the various types of pharmaceutical crystals, and the methods used to determine the structure of pharmaceutical crystals. These topi…
Epiclon [3a,4,5,7a-tetrahydro-7-methyl-5-(tetrahydro-2,5-dioxo-3-furanyl)-1,3-isobenzofurandione] (1) was reacted with L-methionine (2) in acetic acid and the resulting imide-acid 3 was obtained in high yield. The diacid chloride 4 was prepared from diacid derivative 3 by reaction with thionyl chloride. Thermostable p…
Although dioxazolylethene 1a did not show any photocoloration in the single crystalline phase, 1a displayed photochromism in the mixed crystal containing both 1a and dithiazolylethene 2a ; the mixed crystal changed color from colorless to red, orange, and yellow upon irradiation with light of appropriate wavelengths.
A technique using conductivity relaxation on porous bodies was used to determine the oxygen surface exchange coefficient, k chem , of mixed conducting La 0.6 Sr 0.4 Co O 3 − δ (LSC40). The results from the porous bodies were compared with values of k chem obtained on dense samples of LSC40 using the same technique. Co…
Large increases in the efficiency of the Sr 2 Si O 4 : Eu yellow phosphor under the 450 ‐ 470 nm excitation range have been achieved by adding the co-doping element ( Ba 2 + and Mg 2 + ) in the host. In order to apply to white light-emitting diodes (LEDs), we have synthesized a Ba 2 + ∙ Mg 2 + co-doped Sr 2 Si O 4 : E…
The graphite grade ATR-2E was developed as a reference material for future High-Temperature Reactors (HTR) in the framework of Germany‘s former R&D; Programme „HTR with Spherical Fuel Elements“ by the former company Sigri Elektrographit GmbH. From 1975 to about 1990, the former Kernforschungsanlage Jülich GmbH inv…
The biomineralization capacity of the photosynthetic marine diatom Nitzschia frustulum was harnessed to fabricate Si-Ge oxide nanocomposite materials. Germanium was incorporated into the diatom cell by a two-stage cultivation process. In stage 1, the N. frustulum cell suspension was grown up to cell density of 3 x 10(…

Liposomes have been widely used delivery systems, particularly relevant to the development of cancer therapeutics. Numerous liposome-based drugs are in the clinic or in clinical trials today against multiple tumor types; however, systematic studies of liposome interactions with solid or metastatic tumor nodules are sc…
Two new dithiazolylethenes, 1a {1,2-bis[5′-methyl-2′-(2′′-pyridyl)thiazolyl]perfluorocyclopentene} and 2a {1,2-bis[4′-methyl-2′-(2′′-pyridyl)thiazolyl]perfluorocyclopentene}, have been synthesized. Their photochromic behavior has been fully investigated in solution as well as in the crystalline phase. They display bot…
The modelling of dry knitted reinforcements for structural composite parts at the mesoscopic scale is essential to establish simulation tools related to shaping processes. Deformation modes of such structures are linked to the textile's manufacturing process, resulting in an anisotropic heterogeneous structure. This o…
1,10-Phenanthroline-appended cholesterol-based gelators (1 and 2) and their non-gelling reference compounds (1′ and 2′) were synthesized. It was shown that the gelation abilities of 1 and 2 are quite different, in spite of their structural similarity. Compound 1 can form gels with various kinds of organic solvents, wh…
