The redox mediator used in dye-sensitized solar cells present several disadvantages; several research groups have theorized the possible use of blue copper proteins as electron mediators, despite their high costs. Copper complexes that mimic blue copper proteins could represent an alternative as...

Water photolysis to molecular hydrogen and oxygen is one of the most promising chemical reactions for a sustainable hydrogen generation. The search for catalysts for this process is an important research area; some of the most suggested catalysts are manganese complexes. However, several studies...

Diallyl phthalate (DAP) and allyl diglycol carbonate (CR-39), and mixtures of DAP and CR-39 were cast into plates under the same polymerizing conditions. The plates were irradiated with alpha-particles, fission fragments or fast neutrons. After etching, enlarged tracks on the plates were observe...

The isothiourea-catalysed chemo- and enantioselective [2,3]-sigmatropic rearrangement of N,N-diallyl allylic ammonium ylides is explored as a key part of a route to free functionalised α-amino esters and piperidines. The [2,3]-sigmatropic rearrangement proceeds with excellent diastereo- and ena...

Problems associated with water eutrophication due to high phosphorus concentrations and related environmentally safe solutions have attracted wide attention. A novel bis(diallyl alkyl tertiary ammonium salt) polymer, particularly poly(N1,N1,N6,N6-tetraallylhexane-1,6-diammonium dichloride) (PTAH...

A steam distillation process at pH 9 was conducted to prepare garlic oil for food supplement. A garlic oil predominant in bioactive diallyl monosulphide (8.9%), diallyl disulphide (56.9%) diallyl trisulphide (7.6%) and diallyl tetrasulphide (2.6%) was obtained from peeled garlic cloves. The adhe...

A new bead type and diallyl-POSS based polyfluorene (P2) with high symmetrical structure was synthesized via Heck coupling reaction between oligomeric alkynyl fluorene (P1) and diallyl polyhedral oligomeric silsesquioxanes (diallyl-POSS). The molecular weight and the conjugated length of P1 and ...

Diallyl, dibenzyl, and diethyl carbonate are shown to be non-toxic, sustainable and efficient reagents for the alkylation of phenols as well as for an esterification of carboxylic acids under microwave irradiation in the presence of sub-stoichiometric quantities of 1,8-diazabicyclo[5.4.0]undec-7...

In a study aimed at the development of new nuclear track detector, diallyl maleate (DAM) and allyl diglycol carbonate (ADC), and mixtures of DAM and ADC were cast into polymer plates under three kinds of polymerizing conditions. Pure ADC plate was sensitive to both of fission fragments and alpha...

Infrared and Raman spectra of oriented single crystals of dichloro(ethylenediamine)palladium (II), [Pd(en)Cl2], have been investigated. The application of polarized light allowed a determination of the symmetry species of almost all i.r. active bands. Cooling the samples to liquid nitrogen tempe...

Thermodynamic data for equilibria involved int he overall hydrolytic process of the cis-[Pd(en)(H2O)2]2+ complex in the presence or absence of chloride ion are reported. All expected hydrolytic species are taken into account to calculate their formation constants and to fit the equilibrium model...

The substitution reactions of the 2,2′-biquinoline (biq) complex cis-[Pd(biq)Cl2] with different amino acids, namely, glycine (glyH), l-serine (serH), l-tyrosine (tyrH), l-phenylalanine (pheH) and l-alanine (alaH) have been investigated. The new complexes [Pd(biq)(gly)]Cl, [Pd(biq)(ser)]PF6·0....

Aqueous solutions of dichloro(ethylenediamine)palladium(II) were investigated using electrospray mass spectrometry (ESMS). The most abundant peak (m/z 436.8) was attributed to the dimeric Pd(en)Cl2·Pd(en)Cl+ ion. We conjecture that the structures of the observed ions arise from the clustering o...

Formation of the complex between [Pd(en)Cl2] (en = ethylenediamine) and 1-hydroxyethylidene-1,1-diphosphonic acid (HEDP, H4L) was studied by pH-potentiometry, UV–Vis spectrophotometry and 31P NMR spectroscopy in aqueous solutions containing CKCl = 0.15 mol L−1 and 0.004 mol L−1, which correspon...

The quenching of the triplet state of three n-alkyl 3-nitrophenyl ethers: 3-nitroanisol (3-NA), n-butyl 3-nitrophenyl ether (3-NB) and n-decyl 3-nitrophenyl ether (3-ND) by four aniline derivatives: aniline (AN), N,N-dimethylaniline (DMA), 2,4,6-trimethylaniline (TMA), and 4-tetradecylaniline (T...

The synthesis of four new di-n-butyl[bis{dimethyl-2-(3-oxo-5-phenyl(4-subtituted)penten-5-ato)malonates}]tin(IV) 2a–2d is reported. These complexes have been characterized by 1H, 13C, 119Sn NMR, HMQC, HMBC, infrared spectroscopy and mass spectrometry (FAB). Their structures in CDCl3 solution sh...

The molecular and supramolecular structure of the title compound, 3-(tertbutyl)-1-(2-nitrophenyl)-1H-pyrazol-5-amine (2NPz) from the single crystal X-ray diffraction (SC-XRD) and spectroscopic data analysis is reported.

Vf-safe delta-matroids have the desirable property of behaving well under certain duality operations. Several important classes of delta-matroids are known to be vf-safe, including the class of ribbon-graphic delta-matroids, which is related to the class of ribbon graphs or embedded graphs in th...
