In the present study an attempt was made to formulate and evaluate Calcium and Vitamin K3 tablet using wet granulation technique incorporating various Excipients like Starch Powder, Starch Paste, Magnesium Sterate, Aerosil, Talc, Lactose, Vitamin K Liquid form and Water. The Formulated tablets were evaluated for different physicochemical properties like rheological properties, weight variation,...

The main components for tablet formulations are the fillers, binders, crushers, thinners and lubricants. Among these components, binders play a key role on powder cohesion properties during formation of granules. In this study, turmeric extract tablets were formulated using 15 g extract, 35 aerosil, 12.8 lactose, 1% magnesium stearate, 200 ml aquadest gelatin as binder. To evaluate effect formu...

The dynamics of a thixotropic silica aerosil gel dispersed in an octylcyanobiphenyl liquid crystal were directly probed by x-ray intensity fluctuation spectroscopy. For all samples, the time-autocorrelation function of the gel was well described by a modified-exponential function over the q range studied. Compared to a pure gel sample, a dilute (0.06 g cm(-3)) gel embedded within the liquid cry...

The molecular dynamics of [-SiDMe(2)] grafted on two amorphous silica materials, mesoporous SBA and non-porous Aerosil, was investigated by deuteron ((2)H) solid-state NMR spectroscopy. Quadrupole echo (QE), quadrupole Carr-Purcell-Meiboom-Gill (QCPMG) and magic angle spinning (MAS) spectra were recorded as a function of temperature. These were analyzed to determine the rates and trajectories o...

We present a high-resolution study of the isotropic to nematic phase transition of a low birefringence liquid-crystal compound incorporating an aerosil gel. Calorimetry, light scattering, and microscopy data coherently combine to allow for an accurate determination of the temperature dependence of the onset of the nematic state. The nematic order develops on cooling through two distinct process...
