Abstract:Polyaniline carbon paste electrode prepared by mixing polyaniline, parrafin, graphite powder and potassium ferrocyanide a known probe in electroanalysis was analysised. The ratio of polyaniline, parrafin and graphite for the construction of the electrodes and the effect of the concentration of this conducting polymer provides enormous opportunities for electrodes modification, rapid electron transfer and direct communication to produce a range of analytical signals and new analytical applications were studied. These modified electrodes exhibited an increase in surface area and speed up of redox reaction (Bare- 0.014 cm2, Polyaniline- 0.028 cm2). Efforts have been made to discuss and explore various characteristics of PANI responsible for direct electron transfer leading towards fabrication of mediator-less sensors and electrodes reproducibility.

The crystal structure was solved by direct methods and refined by full matrix least-squares procedure to a final R value of 0.054 for 1651 observed reflections. Furan ring adopts envelope conformation. Two phenyl rings are almost perpendicular to each other [dihedral angle = 85.66(7)°]. Crystal packing is stabilized by C-H…O intra molecular and weak C-H…π interactions.

Abstract: The following study was aimed to investigate the potential of Neems tree leaves (Azadirachtaindica) in bioethanol production using Baker's yeast (Saccharomyces cerevisiae) as fermenting agent. Dried powdered leaves of neem tree (Azadirachtaindica) were hydrolyzed using Conc. 2% 5%, and 10% H2S04. And the hydrolyzed samples were it was fermented using Baker's yeast (Saccharomyces cerevisiae). After fermentation the broths formed were distillated to obtained ethanol........

Abstract: Heterocycle synthesis using the transition metal based catalysts has several advantages. In recent years, iron catalysts have been used extensively in the development of synthetic methodologies for this purpose. Different salts of iron can assist bond formations due to their potential as Lewis acids, as oxidizing agents and as convenient catalysts. Fabrications of heterocycles proceed either via C-C bond or C-hetero bond formation from the corresponding acyclic compounds. This review summarises recent contributions from various authors working in this field.

Abstract: Micellar behavior of amitriptyline hydrochloride in aqueous media and presence of NaCl, glucose and urea has been investigated by conductivity measurement over the temperature range 298.15–313.15 K. The conductivity data were used to calculate critical micelle concentration (CMC), degree of counter ion association to the micelle () and degree of dissociation (β) of the micelle of AMT. Thermodynamic parameters viz., standard Gibbs free energy, ΔGm0, enthalpy, ΔHm0, entropy, ΔSm0 of micellization of AMT were estimated by applying the mass–action model.

Abstract: Indigenous vegetables in Akwa Ibom State, Nigeria have been consumed by the people of the region for desire for aroma and taste without finding out their nutritional values. Although researchers have established the fact that vegetables play a vital role in the contribution of essential nutrients to the body which help to maintain a healthy life style and the prevention of diseases. On that note, the proximate compositions: moisture content, total ash, crude fat.............
