Fatigue life, morphological studies, and thermal aging properties of rattan powder-filled natural rubber (NR) composites were investigated as a function of filler loading and a silane coupling agent. NR composites were prepared by the incorporation of rattan powder in the range of 0 to 30 phr into a NR matrix with a laboratory size two roll mill. Thermal aging was carried out for 7 and 14 days ...

Calcium silicate-based materials (also called MTA) are increasingly being used in endodontic applications. However, the handling properties of MTA are not optimal when it comes to injectability and cohesion. Premixing the cements using glycerol avoids these issues. However, there is a lack of data on the effect of common cement variables on important properties of premixed cements for endodonti...

The effects of magnesium stearate, sodium lauryl sulphate (SLS) and talc as lubricants on some powder and tablet properties of silicified microcrystalline cellulose (SMCC) were studied. Single and binary blends of talc, magnesium stearate and SLS at 1% concentration were evaluated as flow modulators on SMCC. Influence of the lubricants on the powder and tablet properties of metronidazole was al...

The use of solid dispersion techniques to modify physicochemical properties and improve solubility and dissolution rate may result in alteration to electrostatic properties of particles. Particle triboelectrification plays an important part in powder processing, affecting end product quality due to particle deposition and powder loss. This study investigates the use of glucosamine hydrochloride...

In this study, mechanically alloyed Al 2024 powder is densified by conventional sintering and by equal channel angular pressing (ECAP) with and without back pressure. The powder was encapsulated in an aluminium can for consolidation through ECAP. The properties obtained in the compacts by conventional sintering route and by ECAP are compared. The effect of conventional sintering and ECAP on con...

Mustard seeds and powder are commonly used inhomeopathic and traditional medicines, in whichthey are believed to have both anti-microbial andanti-inflammatory properties. They are thereforeutilized in the treatment of conditions ranging fromarthritis to respiratory congestion. Herein, we presenta patient with a second degree burn who usedmustard powder in the form of a mustard plasterto treat c...

Powder flow is influenced by environmental factors, such as moisture and static electricity, as well as powder related factors, such as morphology, size, size distribution, density, and surface area. Pharmaceutical solids may be exposed to water during storage in an atmosphere containing water vapor, or in a dosage form consisting of materials (e.g., excipients) that contain water and are capab...

The magnetic properties of an anisotropic Sm2Fe17N3 magnet powder were improved by enhancement of nitrogenation homogeneity. We made the Sm2Fe17 parent material powder by a reduction-diffusion method which contains a reduction-diffusion heat treatment and a subsequent wet process for removal of a CaO by-product. In the present study, as the modified process for the magnet powder, the nitrogenat...

The gamma irradiation has been used for end sterilization of allograft bones and its effects with a 25 kGy dosage on the osteoinductive properties of demineralized bone allograft powder was studied. This work carried out using an experimental method in an animal model. In this study the demineralized bone allograft powder which had been sterilized and prepared with gamma irradiation in a 25 kGy...

The effectiveness of acidity and supplementation with different concentration of sodium chloride salt on function properties for whey protein powder prepared from salted and unsalted whey were investigated. The resultant whey protein powder was in a denatured form and contained about 50% protein. Whey protein powder from salted whey was generally more water soluble at any particular pH values (...
