Based on direct sucrose conversion, the bacterium Burkholderia sacchari is an excellent producer of the microbial homopolyester poly(3-hydroxybutyrate) (PHB). Restrictions of the strain's wild type in metabolizing structurally related 3-hydroxyvalerate (3HV) precursors towards 3HV-containing polyhydroxyalkanoate (PHA) copolyester calls for alternatives. We demonstrate the highly productive bios...

Abstract Increasingly evidence seems that from the biological samples—mainly summation of DSC scans human blood plasma—can be separated into main and well-known components by deconvolution method. This fact alone could an important advance in thermoanalytical research, but mostly, it has not been detected soft tissues yet. The other reason was our previous studies, histological examinations did...

New nanocomposites composed of cellulose nanofibers or "whiskers" and an epoxy resin were prepared. Cellulose whiskers with aspect ratios of approximately 10 and approximately 84 were isolated from cotton and sea animals called tunicates, respectively. Suspensions of these whiskers in dimethylformamide were combined with an oligomeric difunctional diglycidyl ether of bisphenol A with an epoxide...

Two new complexes, [Cu(dimpyr)2(H2O)2](NO3)2.2H2O (1) and (Hamdimpy)2[CoCl4].H2O (2), with the monodentate ligand 2-amino-6-methylpyrimidin-4-(1H)-one (dimpyr) countercation 4-amino-2,6-dimetylpyrimidium (Hamdimpy), respectively, were prepared characterized by single crystal X-ray diffraction, elemental analysis IR spectroscopy. In (1), Cu(II) cation is tetracoordinated, in a square plan fashio...

The hydrothermal reaction of M(NO3)2.6H2O (M = Ni and Zn) with benzene-1,3,5-tricarboxylic acid (H3btc) and 1,2-bis(1,2,4-triazol-4-yl)ethane (btre) produced the mixed-ligand coordination polymers (MOFs) 3 infinity{[Ni3(mu3-btc)2(mu(4)-btre)2(mu-H2O)2]. approximately 22H2O} (1) and 3 infinity{[Zn3(mu4-btc)2(mu4-btre)(H2O)2].2H2O} (3). The compounds, characterized by single-crystal X-ray diffrac...

The VO(IV) complexes of tridentate ONO Schiff base ligands derived from 2- aminobenzoicacid and salicylaldehyde derivatives were synthesized and characterized by IR, UV–Vis and elemental analysis. Electrochemical properties of the vanadyl complexes were investigated by cyclic voltammetry. A good linear correlation was observed between the oxidation potentials and the electron-withdrawing charac...

Self-assembly of molecules on surfaces directed by different supramolecular interactions has been widely explored. There are striking examples of molecular surface structures, whose formation is driven by metal co-ordination[1], dipolar coupling[2] or hydrogen bonding[3] interactions. In contrast to these examples, our aim is the formation of covalently linked planar structures by means of poly...
