the migration of aluminum (al) from aseptic laminated paperboard packages was studied by monitoring the al content of orange juice (plain juice, no additives) filled into such packages and stored at ambient temperature (23ºc) for up to 1 year. analytical procedure includes mw-assisted digestion of orange juice with concentrated nitric acid followed by determination of al concentration by double-...

In an earlier study, an electronic tongue system (e-tongue) has been used to differentiate between orange juice made from healthy fruit and from fruit affected by the citrus greening or Huanglongbing (HLB) disease. This study investigated the reaction of an e-tongue system to the main chemicals in orange juice that impact flavor and health benefits and are also impacted by HLB. Orange juice was...

This study was conducted to evaluate the effect of plant growth regulators on in vitro shoot multiplication, vitrification and rooting of two carnation cultivars (Eskimo Mogr and Innove Orange Bogr). Isolated axillary buds were cultured on MS medium supplemented with different levels of Benzyl amino purine (BAP) or kinetin (Kin) in combination with 0.2 mg/l NAA and shoot multiplication and vitr...

In this study, a new reaction system for quantitative determination of ascorbic acid was introduced. The developed method is based on inhibitory effect of ascorbic acid on the Orange G-bromate system. The change in absorbance was followed spectrophotometrically at 478 nm. The dependence of sensitivity on the reaction variables including reagents concentration, temperature and time was investiga...

A ternary adduct made up of trinitrobenzene, 2-amino-5-chloropyridine and 9-anthracenecarboxylic acid crystallizes out in two polymorphic forms. The adducts, orange red coloured, are a further example the salt/co-crystal continuum.

Beers, Roland F., Jr. (Johns Hopkins University, Baltimore, Md). Acridine orange binding by Micrococcus lysodeikticus. J. Bacteriol. 88:1249-1256. 1964.-Micrococcus lysodeikticus cells bind acridine orange (AO) reversibly. The adsorption isotherm is consistent with a highly cooperative-type binding similar to that observed with polyadenylic acid. The cells exhibit a strong buffering action on t...

A substrate-free, large-scale, free-standing and two-side oriented single crystal rutile TiO(2) nanorod array film with a thickness of over ten micrometers, self-assembled via a facile hydrothermal reaction of titanium powder in a mixture solution of H(2)O(2) and HCl, exhibits high activity for the photocatalytic degradation of methyl orange.

We develop a facile method to immobilize cucurbituril on silicon substrates through photochemical reaction with azido groups. Combining photolithography and the competitive molecular recognition between CB[7] and acridine orange base or 1-adamantanecarboxylic acid, a patterned surface with reversible fluorescence emission can be obtained.

Kinetics of anaerobic biodecolourisation (methanogenic environment) of four azo dyes (Acid Orange 6, Acid Orange 7, Methyl Orange and Methyl Red) was investigated with regard to their electrochemical properties as well as under variation of dye and sludge concentrations, pH and temperature. Cyclic voltammetry revealed a correlation between the potential of irreversible reduction peak of the dye...
