Polystyrene/Sr2Ce2Ti5O15 composites with low dielectric loss for microwave substrate applications

Abstract: Sr2Ce2Ti5O15 (Strontium Cerium Titanate or SCT) ceramic was prepared by solid-state route. A composite of polystyrene/Sr2Ce2Ti5O15 was made using melt mixing technique in a Kneading machine. The microstructure of the composite was investigated using a Scanning Electron Microscope. The dielectric properties of the composites were studied at radio frequency and microwave frequencies. It is observed that relative permittivity and loss tangent increase with volume fraction of the ceramics. The mechanical properties of the composites were investigated using microhardness tester. For 50 volume percentage loading of the ceramic, the composite has relative permittivity of 13.6 and dielectric loss of 4.28 3 10 24 . The experimentally observed permittivity was compared with the theoretical models. POLYM. ENG. SCI., 49:1218–1224, 2009. a 2009 Society of Plastics Engineers

Vibrios associated with Macrobrachium rosenbergii (De Man, 1879) larvae from three hatcheries on the Indian southwest coast

Abstract: Surveys for bacteriological analysis of larval samples to isolate the associated vibrios were carried out during 1985^1992, 2001 and 2002 in three diierent hatcheries located on the southwest coast of India. Vibrio isolates were examined for their species diversity, virulence based on haemolysis in prawn blood agar, lipolysis, proteolysis and chitinolysis and antibiotic sensitivity.Vibrio cholerae was the predominant species in the apparently healthy larval samples, whereas V. alginolyticus and V. vulni¢cus dominated during disease and morbidity. No correlation was found between the hydrolytic properties and haemolytic activity of the vibrios associated with the larvae. All isolates were resistant to erythromycin and resistance to oxytetracycline, ampicillin and streptomycin sulphate was prevalent among the larger section of the Vibrio population. This suggested that antibiotic application may not be of much use to protect the larvae from vibriosis. This is the ¢rst report on the diversity of Vibrio species associated with Macrobrachium rosenbergii larvae and their virulence characteristics based on haemolysis in prawn blood agar.

Synthesis of chemically pure, luminescent Eu3+ doped HAp nanoparticles: a promising fluorescent probe for in vivo imaging applications

Abstract: The poor solubility, poor biocompatibility and disposal issues make fluorescent quantum dots such as CdSe, CdS, ZnS, InP, InAs, etc. impractical for imaging tissues or intercellular structures. As calcium phosphate is the main inorganic component of human bone and teeth, hydroxyapatite (Ca10(PO4)6(OH)2, HAp) is highly biocompatible and bioactive. Since HAp nanoparticles are not luminescent, a novel inorganic biocompatible fluorescent probe was suggested by doping HAp with lanthanides. Here we report the growth of chemically pure fluorescent HAp nanoparticles synthesized by a new methodology, liquid phase pulsed laser ablation using third harmonics (355 nm) of Nd-YAG laser. Europium doped HAp nanoparticles show emission with prominent peaks at 531 nm, 572 nm, 601 nm and 627 nm upon excitation at a wavelength of 325 nm. The red luminescence could also be observed under visible excitation at 459 nm and is suitable for living cell applications.
