Formulation Development, Characterization and in-vitro Evaluation of Nano-Lipid Carriers of Ropinirole HCl for Persistent Parkinsonian Management
Abstract: According to a report of World Health Organization (WHO) 2014, Parkinson's Disease (PD) is the second-most neurodegenerative dysfunction of the central nervous system (CNS) of human being effecting 7–10 million people worldwide. It is primarily due to the death of dopamine-generating cells in the substantia-nigra of midbrain. It is symptomatized by tremor, rigidity, bradykinesia, dementia, depression and falls or emerges with the progression of the disease. Ropinirole HCl is a …

A Review on Novel Emulsification Technique: A Nanoemulsion
Abstract: Kinetically stable and isotropic system of submicron size range is the nanoemulsion. In this system two immiscible liquids are mixed together to form a single-phase system with the identical concentration and ratio of surfactant and cosurfactant. Nanoemulsion droplet sizes fall typically in the range of 20- 200 nm. Some literature suggest this range below 100 nm with shows narrow size distribution. In this review, major focus is given on the …

Effect of Hafnium on Nickel-Titanium based Thin Film Coating by DC/RF Magnetron Sputtering Technique
Abstract: Ni-Ti-Hf films as shape memory alloys were successfully prepared by magnetron sputtering technique using individual Ti, Ni and Hf targets. The hafnium content was varied from 6% to 30% and the required film composition was achieved by adjusting the power ratio to the targets. The as-deposited films were amorphous; a post deposition annealing was performed at 700 °C to crystallize the Ni-Ti-Hf films. Structural, compositional and phase-transformation studies were carried …

Isolation, Identification and Characterization of Bdellovibrio sp. from Soil and its Antibiotic Potential against Selected Bacterial Pathogens
Abstract: Bdellovibrio and Like Organisms (BALOs) are the world's smallest Gram-negative, highly motile delta-proteobacterial predators generally found in diverse environmental niches such as soil, seawater, sewage, bio films, freshwater, gastro intestinal tract of animals and in association with plant roots. These small bacteria attack gram negative bacterial strains attaching to the outer membrane and consuming the prey extracellularly (epibiotic predation) or penetrating their periplasm (periplasmic predation). Bdellovibrio exovorus MPR11 (Accession No. …

Dye Sensitized Solar Cells Based on Extracted Natural Dyes and Synthetic Dyes with Nanocomposite Material
Abstract: Producing dye sensitised solar cells in their original colours required a number of different techniques. Plants and berries were used to extract these dyes. The DSSCs were manufactured by recycling the old dyes. It was clear that the efficiency of the power conversion was deteriorating. TiO2 mesoporous films' potential applications were also studied. This study employed electrochemical impedance spectroscopy to examine the interactions of natural dyes with TiO2. Bi2O3 nanoparticles …

Dynamic deformation and microstructural characteristics of AA5083 under the influence of electrochemical behaviour using equal channel angular pressing
Abstract: Large-scale Equal channel angular pressing is a great engineering material that has more potential for AA5083 industrial applications. Uniaxial dynamic compressive tests across a temperature of 448 K were conducted for the ECAP technique AA5083 in order to create such a design framework. The microstructure was described using transmission electron microscopy and scanning electron microscope both before and after dynamic loading. The plastic flow behaviour of the AA5083 was described …
