A greenhouse experiment was conducted to compare the subcellular distribution and chemical forms of cadmium (Cd) in roots, stems, leaves, and fruits between a low-Cd cultivar (Yeshengchaotianjiao, YCT) and a high-Cd cultivar (Jinfuzaohuangjiao, JFZ) of hot pepper (Capsicum annuum L.). The Cd concentrations in the root's subcellular fractions, and in all chemical forms in roots, were 1.85-4.88- ...

Catalytic intramolecular hydrofunctionalization of allylphenols to heterocyclic compounds mediated by rhodium(iii) porphyrin complexes was described. The Wacker-type intermediate β-heterocyclic alkyl rhodium complex was independently synthesized and crystallized.

Photolysis of porphyrin-ruthenium(IV) dichlorate complexes with visible light results in homolytic cleavage of the O-Cl bond in the chlorates to form trans-dioxoruthenium(VI) species bearing either sterically encumbered or unencumbered porphyrin ligands.

During the last years, we have performed systematic calculations on the vibrational properties of simple molecules and ions containing interhalogen bonds. Surprisingly, during our literature searches we found that detailed information on the mean amplitudes of vibration of the halogen molecules themselves ar not available. In the classic work of Cyvin [1] only a brief mention of these values fo...

the antioxidant potential of crude methanol extract (ce) as well as chloroform (cf), ethyl acetate (ef) and n-butanol (nf) soluble fractions of enhydra fluctuans lour, which is widely used in indigenous system of medicine for different purposes, were studied. the antioxidant potential of extract/different fractions were evaluated using different in vitro antioxidant models. in addition, total a...

we investigate the long-term behavior of solutions of the difference equation[ x_{n+1}=x_{n}x_{n-3}-1 ,, n=0 ,, 1 ,, ldots ,, ]noindent where the initial conditions $x_{-3} ,, x_{-2} ,, x_{-1} ,, x_{0}$ are real numbers.  in particular, we look at the periodicity and asymptotic periodicity of solutions, as well as the existence of unbounded solutions.
