Calcium carbonate aragonite polymorph nanoparticles derived from cockle shells were prepared using surface functionalization method followed by purification steps. Size, morphology, and surface properties of the nanoparticles were characterized using transmission electron microscopy, field emission scanning electron microscopy, dynamic light scattering, zetasizer, X-ray powder diffraction, and ...

Abstract. The effect of building orientations, sample conditions, and loading ratio (R-value) are important factors in terms fatigue behavior. aim this paper is to investigate the that affect behavior additively manufactured laser powder-bed fusion (LPBF) 316L stainless steel. A statistical analysis was performed point significant insignificant with different samples R-value. This provides most...

Mucoadhesive polymeric (carbopol 934) suspension of ciprofloxacin was prepared by ultrasonication and optimized with the aim of developing an oral controlled release gastro-retentive dosage form. The qualitative analysis of the formulation was performed by fourier transform infrared spectroscopy (FTIR), Raman spectroscopy, X-ray powder diffraction (XRD), and scanning electron microscopy (SEM) a...

Mucoadhesive polymeric (HPMC) suspension of Ciprofloxacin was prepared by ultrasonication and optimised with the aim to develop an oral controlled release gastroretentive dosage form. The qualitative analysis of the formulation was performed by Fourier Transform Infrared Spectroscopy (FTIR), Raman Spectroscopy, X-ray powder diffraction (XRD) and Scanning electron microscopy (SEM). FTIR (400 cm ...

In this study, the removal of Pb(II) from aqueous solutions by tassel powder was studied and optimised. Batch experiments were conducted on simulated solutions using tassel powder adsorbent and the effects of contact time, pH and concentration on the extent of Pb (II) removal was studied. Equilibrium and kinetic models for Pb(II) sorption were developed by considering the effect of contact time...

Dichloromethane (DCM) and acetonitrile (ACN) are the most commonly used solvents for polylactic acid (PLA) or poly(lactic-co-glycolic acid) (PLGA). In order to select a suitable solvent system for the preparation of PLGA microspheres containing tumor necrosis factor-alpha (TNF-a), the stability of TNF-a when mixed with DCM and ACN under various phase conditions was investigated. When the TNF-a ...

Objectives: The aim of the present study was to evaluate effects of various polymers on the release of a water soluble drug by using spray drying technique of microencapsulation. Methods: Spray drying is a single step technique, less time is required and loading efficiency is not affected by the nature of the drug whether hydrophilic or hydrophobic. Eudragit RS 30D, RL 30D and Ethylcellulose (S...
