BACKGROUND Polygonum hydropiper L decoctions are traditionally used in the treatment of various ailments including inflammation, dyspepsia, diarrhea, menorrhagia, hemorrhoids, helminthiasis and CNS disorders. Present study was undertaken to investigate P. hydropiper L. for heavy metals content, phytoconstituents, Phytotoxic and anthelmintic activities to explore its toxicological and pharmacolo...

Powder Metallurgy (PM) is a forming technology that uses metallic (sometimes also in conjunction with ceramic) powders to develop parts, most of the time through thermal process called sintering, which never reaches melting point principal component alloy [...]

Orthopedic components, such as the acetabular cup in total hip joint replacement, can be fabricated using porous metals, such as titanium, and a number of processes, such as selective laser melting. The issue of how to effectively remove loose powder from the pores (residual powder) of such components has not been addressed in the literature. In this work, we investigated the feasibility of two...

The fixation of heavy metals (Ba, Cu, Pb) in an alkali-activated matrix was investigated. The matrix consisted of fly ash and blast furnace slag (BFS). The mixture of NaOH and Na-silicate was used as alkaline activator. Three analytical techniques were used to describe the fixation of heavy metals-X-ray photoelectron spectroscopy (XPS), scanning electron microscopy (SEM) equipped with energy di...

abstract aims: spices are sources of many bioactive compounds that can improve the taste of food as well as affecting the digestion and metabolism. along with that, they may also contain some substances as heavy metals, which have harmful effects on the body. the aim of present study was to assess the potential health risk of cr, cu, fe and zn contents of cardamom, curry powder and turmeric in ...

magnesium is potentially useful for orthopedic and cardiovascular applications. magnesium and its alloys are light, biodegradable, biocompatible metals that have promising applications as biomaterials. however, the corrosion rate of this metal is so high that its degradation occurs before the end of the healing process. one of the ways to improve the corrosion rate is to compose it with ceramic...

The exponential increase of industrial demand in the past two decades has led scientists to the development of alternative technologies for the fast manufacturing of engineering components, aside from standard and time consuming techniques such as casting or forging. Cold Spray (CS) is a newly developed manufacturing technique, based upon the deposition of metal powder on a substrate due to hig...

While GDMS is the technique of choice for high sensitivity metals and semiconductor analyses, there are no commercially available radio frequency-GDMS sources. Thus, bulk non-conductive materials must be ground to a powder, mixed with metal, and pressed to form a conductive disk. The analysis of thick oxide or polymer layers is not available directly. In some cases, a conductive metal mask (cal...
