A near infrared (NIR) method able to directly quantify the active content in pharmaceutical powder blends used for manufacturing meloxicam tablets, without any sample preparation, was developed and fully validated. To develop calibration models for the assay of meloxicam in powder blends for tableting, the NIR reflectance spectra of different meloxicam powder blends prepared according to a cali...

Wet granulation using foaming binder solution is a new approach of liquid delivery to create granules. This study compares wet granulation via foamed binder addition method and sprayed binder addition method by studying the kinetics of foam and drop penetrations into loosely packed powder beds. Foam and drop nucleation kinetics were compared by examining specific penetration time (penetration t...

− In this paper a cost-effective method for measuring transportation velocity and the velocity profile of a material flow of powdery solids inside a pipe is presented. For the measurement, artificial perturbations are brought into the mass flow and the effects of these perturbations are acquired and correlated at measurement sections. The velocity profile is calculated with the knowledge of the...

date syrup powder is a new product which can be used as sugar substitute. first, the date syrupwas spread out on a foil and placed in the oven at 60°c for 24 hours. date syrup was separated from the foil andgrinded. 2% agar and 2% starch were added and syrup with agar and starch that was in a lumpy shape werecrushed and spread on the foil and placed at 60°c for 24 hours. powdered granules, agar...

During the recent years powder processing technologies have gained much attention due to the less energy consumption and recyclable powders. Manufacturing of complicated parts by the conventional powder metallurgy (PM) method is hard due to the uniaxial pressure, which leads to the low design flexibility. In order to prevail these constraints, powder injection molding (PIM) process, which inclu...

A novel extension to a previous method has been proposed to evaluate the nature of dry powder mixing processes using a mixing sensitive colouring agent. The method proposed measures the change in the colour (hue) and colour intensity of the powder blends over mixing time. To evaluate the extent of fine particle dispersion and de-agglomeration, cohesive and free flowing lactose (white) and cohes...

storage of hydrogen is one of the key challenges in developing hydrogen economy. magnesium hydride (mgh2) is an attractive candidate for solid-state hydrogen storage for on-board applications. in this study, 10 wt.% zrb2 was co-milled with magnesium hydride at different milling times to produce nanocrystalline composite powder. the effect of milling time and additive on the hydrogen desorption ...

The Rietveld method of structure refinement with powder diffraction patterns was originally devised for the analysis of fixed-wavelength (angle-dispersive) neuron data [1] [2] but now constitutes a major breakthrough for the usefulness of X-ray powder data [3]. This powerful method has greatly extended the amount of structural detail which can be obtained routinely from powder diffraction patte...
