Natural dyes obtained from plants, vegetables and fruits are widely studied and tested as low cost sensitizer for dye sensitized solar cell ( DSSC) in order to replace the rare and expensive inorganic and organic sensitizers. Although, many works have been done using TiO2, ZrO2, ZnO etc. as the nanoporous semiconductor, little importance was given to the use of CdS thin film as a cost effective...

In Indonesia, Caesalpinia pulcherrima (L) Swartz is widely grown as an ornamental, whereas it is used as a medicinal herb in Mexico as an alternative treatment for dental and oral infections. At present, only fruit and root parts of the plant are used. The aim of this study was is evaluate the anti-microbial activity of ethanol extract of fruit, leaves, flowers and stems against microbes that c...

The isolation of lectins by affinity chromatography with crosslinked hemicelluloses has been a common practice because the variety glycosides that they present, improving different kinds lectins, such as galactose ligands.Lectins for carbohydrates is so specific simple configuration chiral carbon can affect affinity, and there are more related to alfa-galactosidic than beta-galactosidic residue...

Phytoplasma infection causes a desirable branching phenotype in the ornamental plant Euphorbia pulcherrima by releasing apical dominance. Four E. pulcherrima genes specifically regulated during phytoplasma infection were identified using differential display of cDNA-PCR products. According to BLAST searches the possible functions of the identified genes included a histidinecontaining phosphotra...
