Controlling and unraveling structural polymorphism has received special attention in 2D self-assembled monolayers. In this work, we investigated the steric matching and solution concentration controlled structural variety in the self-assembly of 2,7-bis(n-alkoxy)-9-fluorenone (F-OCn) at the n-tetradecane and n-tridecane/graphite interface under different concentrations, respectively. Scanning t...

Article history: Received on: 16/01/2013 Revised on: 06/03/2013 Accepted on: 04/04/2013 Available online: 27/04/2013 Bambusa arundinacea locally known as Bans or bamboo, a perennial fastest growing plant. This plant is medicinally much famous. The biological activities of this plant were carried out by using standard procedures. The aim of this work was to investigate the in vitro antimicrobial...

The morphology and ultrastructure of the metathoracic scent glands (MTG) of Eurygaster maura were studied by scanning electron microscopy (SEM) and transmission electron microscopy (TEM). Also, extracts of the volatile fraction of the MTG secretion from males and females were analyzed by capillary gas chromatography-mass spectrometry (GC-MS). In SEM investigations, MTG are composed of a reservo...

Utilization of various hydrocarbons by microbes is well known (Beerstecher, 1954), but little has been reported on the cellular composition of hydrocarbongrown cells. No doubt it has been assumed that these cells differ little from those cultivated on nonhydrocarbon substrates and, in general, this assumption is probably true. But it is recognized that substrates and cultural conditions can inf...

The chemotaxis behavior of the plasmodial stage of the true slime mold Physarum Polycephalum was assessed when given a binary choice between two volatile organic chemicals (VOCs) placed in its environment. All possible binary combinations were tested between 19 separate VOCs selected due to their prevalence and biological activity in common plant and insect species. The slime mold exhibited pos...

The Conventional Laser Absorption Scattering (C-LAS) technique is used to measure the mixture concentration and visualize vapor phase. former determined by attenuation of visible ultraviolet light whereas latter achieved via absorption scattering theory. C-LAS uses Nd: YAG pulsed laser CCD cameras provide one spray shot at a particular instance which requires time effort. However, temporal meas...

BACKGROUND Some strains of plant growth-promoting rhizobacteria (PGPR) elicit induced systemic resistance (ISR) by emission of volatile organic compounds (VOCs) including short chain alcohols, acetoin, and 2,3-butanediol. The objective of this study was to evaluate whether species-specific VOCs from PGPR strain Paenibacillus polymyxa E681 can promote growth and induce resistance in Arabidopsis....

An obligately thermophilic strain ZY-10 was isolated from the crude oil in a high-temperature oilfield, which was capable of degrading heavy crude oil. Phenotypic and phylogenetic analysis demonstrated that the isolate should be grouped in the genus Geobacillus, which shared thd highest similarity (99%) of the 16S rDNA sequence to Geobacillus stearothermophilus. However, the major cellular fatt...
