Talanta. 2015 Sep 01;142:221-7. doi: 10.1016/j.talanta.2015.04.052. Epub 2015 Apr 27.

A simple and sensitive electroanalytical method was developed for determination of nanomolar levels of Pb(II) based on the voltammetric stripping response at a carbon paste electrode modified with biochar (a special charcoal) and bismuth nanostructures (nBi-BchCPE). The proposed methodology...

Chemistry. 2014 Aug 18;20(34):10661-8. doi: 10.1002/chem.201402021. Epub 2014 May 02.

We have designed a new multichromophoric system based on a tetra(phenylthio)pyrene core appended with four terpyridine units. The system behaves as a molecular antenna that collects light with the peripheral units and funnels the energy to the very highly...

Dendrimers with a pentaphenylene core: a photophysical study.

Chemphyschem : a European journal of chemical physics and physical chemistry

PMID: 19035606
Chemphyschem. 2009 Jan 12;10(1):265-9. doi: 10.1002/cphc.200800597.

Novel dendrimers G2PC and G4PC consisting of a p-pentaphenylene core (PC) appended in the para position with two second-generation (G2) or two fourth-generation (G4) sulfonimide branches and two n-octyl chains, as well as a model compound of the pentaphenylene...

We have investigated the fluorescence properties of dendrimers (Gn is the dendrimer generation number) containing four different luminophores, namely terphenyl (T), dansyl (D), stilbenyl (S), and eosin (E). In the case of T, the dendrimers contain a single p-terphenyl...

Data on vulnerability to injury and on the larger age-related accumulation of lipofuscin in the subendocardial myocardium prompted us to investigate the changes in the levels and in the transmural distribution of catalase (C), glutathione peroxidase (GSH-Px) and superoxide...

Conditional deletion of TrkB alters adult hippocampal neurogenesis and anxiety-related behavior.

Brain-derived neurotrophic factor (BDNF) is a member of the neurotrophin family, which has been reported to regulate neurogenesis in the dentate gyrus, but the molecular control over this process remains unclear. We demonstrated that by activating TrkB receptor tyrosine...

Supported nanometric titanium oxide sols as a new efficient photocatalyst.

A new octacationic macrocycle, tetrakis-2,3-[5,6-di{2-(N-methyl)pyridiniumyl}pyrazino]porphyrazine, was obtained in its hydrated form as the water-soluble iodide salt. This compound, abbreviated as [(2-Mepy)(8)TPyzPzH(2)](I(8)).8H(2)O (2-Mepy = 2(N-methyl)pyridiniumyl moiety), was obtained by demetalation of the corresponding Mg(II) complex, [(2-Mepy)(8)TPyzPzMg(H(2)O)](I(8)).5H(2)O, which in turn was...
