The work presented in this paper was undertaken as part of BIOCOMP (2005-2008), a European collaborative project, which developed new classes of engineering composite materials from renewable resources. Comprising twenty five European SMEs and research organisations, this three and a half year project generated a wide range of new biocomposite materials, knowledge-based processes and demonstrat...

Photocatalytic H2O2 production by conversion of O2 in aqueous solution is often challenged the use sacrificial agents, separation powdery photocatalysts, solution, and contaminants, low activity photocatalyst. Herein, a membrane covalent furan-benzimidazole-linked polymer (Furan-BILP) with both O- N-containing heterocycles bonded via OCCN reported for first time as photocatalyst to harvest c...

The title compound, C(17)H(18)N(2)O(4), is the methyl ester of the adduct of intra-molecular Diels-Alder reaction between maleic anhydride and 1-(2-fur-yl)-2,3,4,5-tetra-hydro-1H-pyrrolo-[1,2-a][1,4]diazepine. The mol-ecule comprises a fused penta-cyclic system containing four five-membered rings (viz. pyrrole, 2-pyrrolidinone, tetra-hydro-furan and dihydro-furan) and one seven-membered ring (1...

3-Benzyl-furan-2(5H)-one (2a) and 3-(4-bromobenzyl)-furan-2(5H)-one (2b) were treated with TBDMSOTf and converted into the corresponding tert-butyldimethyl-silylfuran ethers. These furans were further condensed with several aromatic aldehydes affording compounds 5-14 with general 3-benzyl-5-arylidene-furan-2(5H)-one structures in 31% to 98% yields. Such compounds are analogues of the naturally ...

2-Nitroaryldifurylmethanes 1a and 1b, readily available by condensation of 2-nitrobenzaldehyde and 6-nitroveratraldehyde with 2-methylfuran, were transformed into indole, cinnoline and benzothiazine-3,1 derivatives. The reduction of 2-nitroaryldifurylmethanes gave the corresponding anilines 2a,b or indole 3 depending on the reaction conditions. A plausible mechanism for the last reaction involv...

In the mol-ecule of the title compound, C(15)H(13)Cl(2)N(3)O(2), the triazole ring is oriented at dihedral angles of 2.54 (13) and 44.43 (12)°, respectively with respect to the furan and dichloro-benzene rings. The dihedral angle between the dichloro-benzene and furan rings is 46.75 (12)°. In the crystal structure, inter-molecular C-H⋯O hydrogen bonds link the mol-ecules into centrosymmetric di...

The anti-biotic nitro-furan-toin {systematic name: (E)-1-[(5-nitro-2-fur-yl)methyl-idene-amino]-imidazolidine-2,4-dione} crys-tallizes as a methanol monosolvate, C(8)H(6)N(4)O(5)·CH(4)O. The nitro-furan-toin mol-ecule adopts a nearly planar conformation (r.m.s. deviation = 0.0344 Å). Hydrogen bonds involve the co-operative N-H⋯O-H⋯O heterosynthons between the cyclic imide of nitro-furan-toin an...

Electronic excitation spectra of furan and pyrrole are reinvestigated by the symmetry-adapted cluster configuration-interaction method. The 47 and 46 lowest singlet and triplet electronic states are computed for furan and pyrrole, respectively. Two series ~1a2 and 2b1! of low-lying Rydberg states and the valence p–p* excited states strongly influence each other in both furan and pyrrole. The pr...

This paper deals with three types of power transformer failure analysis tests which can help in monitoring the transformer condition. The three methods are Conventional oil test, Furan derivatives test and Markov models criteria. Conventional oil testing procedure includes determination of gas concentrations in the transformer oil sample and analyzing the fault by considering ratio of two suita...
