Aceclofenac, a non-steroidal antiinflammatory drug, is used for posttraumatic pain and rheumatoid arthritis. Aceclofenac fast-dispersible tablets have been prepared by direct compression method. Effect of superdisintegrants (such as, croscarmellose sodium, sodium starch glycolate and crospovidone) on wetting time, disintegration time, drug content, in vitro release and stability parameters has ...

The physicochemical and microbial properties of soil under long-term monoculture winter wheat were studied to assess the effects two tillage systems different intensities: reduced (RT) conventional (CT). research was carried out on an 18-year-old experimental field at Grabów (eastern Poland) between 2018 2020. RT (ploughless) CT (mouldboard ploughing) with machine operating depths up 10 25 cm, ...

Milling is a critical step to prepare plant-based food ingredients by dry fractionation. It should provide dispersible flour of finely milled particles composed different cellular substructures. Especially, for raw materials with higher oil content such as soybean, this challenging. We present an investigation on the effect milling yield, particle size, energy use and dispersibility upon pin-mi...

The mechanical properties of non-vulcanized natural rubber and dialyzed natural rubber-clay nanocomposites have been studied by uniaxial deformations to evaluate the reinforcement efficiency of the clay. We show that while non-rubber molecules contribute to auto-reinforcement, removal of these molecules improves significantly the performance of clay as reinforcement agent. These mechanical prop...

[1] To understand the aqueous history of Mars, it is critical to constrain the alteration mineralogy of the Martian surface. Previously published analyses of thermal infrared (l = 6–25 mm) remote sensing data of Mars suggest that dark regions have 15–20% clay minerals. However, near-infrared (l = 1–3 mm) spectral results generally do not identify widespread clay minerals. Thermal infrared detec...

This study investigates the removal of tungsten from simulated water using biopolymer coated particles (i.e. chitosan coated clay) and natural clay. The effects of initial tungsten concentration (from 20 to 500 ppm) and water pH (4, 5.5 and 6.4) on zeta potential and tungsten removal were studied for both chitosan coated clay and natural clay. It was found that the net surface charge of natural...
