After preliminary investigations o f the B a -N a N system, resulting in the discovery of the first sub-nitride NaBa3N [1], we decided to examine more closely the intermetallic phases formed by the two metals, leading to the discovery of the new Laves phase N a2Ba. The literature contains a variety o f conflicting reports concerning N a -B a intermetallic phases. The standard references for bin...

Consuming small-sized fish species whole, and bones of large fish could contribute significantly to reducing the level of micronutrient and protein malnutrition. These fish products are more affordable and could therefore meet the needs of poor, vulnerable groups, particularly in rural and urban areas where limited economic resources prevent dietary diversity. The objectives of the study were t...

Abstract The limited access to materials for the Powder Bed Fusion of Metals using a Laser Beam (PBF-LB/M) is compensated by in situ alloying. Individual melt pool characteristics can be specifically influenced improve mechanical properties final part. However, conventional PBF-LB/M machines allow only detailed observation process zone and, particular, pool. This paper presents methodology syst...

The pharmaceutical industry liquid waste is one of the wastes that have potential to produce containing heavy metals. One highest metal contaminants originating from lead (Pb). Pb can cause health problems and pollute environment. way treat by adsorption process using bioadsorbent. eggshell be used as an adsorbent absorb contains calcium carbonate, therefore it adsorbent. This study aims determ...

Abstract The immobilization effect of soil amendments on leaching and bioavailability Pb, Zn Cd in highly contaminated soils under industrial impact was studied by collecting the surroundings Zn-Pb Smelter “Miasteczko Śląskie” southern Poland as an example. Various amounts four additives (phosphate fertilizer, limestone powder, bentonite rock bog iron ore) were tested laboratory experiments to ...

Gold is used in various fields and a rare resource nature. Recovery of gold from domestic wastes desired Japan. Bamboo an abundant biomass Japan, the promotion its utilization desired. In our previous studies, sulfur-impregnated carbonaceous adsorbent with high heavy metal removal has been prepared resources using sulfur affinity for metals. this study, bamboo was powder by pyrolyzing at 800°C ...

Sediment sampled from Taichung Harbor was mixed with local reservoir sediment at different weight ratios to prepare lightweight aggregate at 1050, 1100, and 1150 degrees C. A pressure of 3000 or 5000 psi was used to shape the powder mixtures into pellets before the heating processes. The results indicate that the leaching levels of trace metals from the lightweight aggregate samples are conside...

Cyanocobalamin occurs as dark red crystals or orthorhombic needles or crystalline red powder. It is very hygroscopic in the anhydrous form, and sparingly to moderately soluble in water (1:80). Its pharmacologic activity is destroyed by heavy metals (iron) and strong oxidizing or reducing agents (vitamin C), but not by autoclaving for short periods of time (15-20 minutes) at 121°C. The vitamin B...

A number of new solvates and adducts containing bisphenyldimethylaminophosphine oxide is reported. The solvates have the general formula M [ (C6H5) 2P (O) N (CH3) 2 ] 4 2 + (anion") 2 , in which M = Mg, Ca, Mn, Fe, Co, Ni, Cu, Zn and Cd, and the anions are C104~ and BF4". The adducts have the general formula M [ (C8H5) 2P (O) N (CHS) 2 ] 2C12 , where M stands for the same series of metals. The ...

To utilize a typical squid processing by-product, hepatopancreas was enzymatically hydrolyzed, then subjected to a plastein reaction. The substrate concentration that gave the highest plastein yield was 30% by using Alkalase. The optimum pH for the plastein synthesis with Alkalase ranged from 6 to 9. The dominant molecular size of the formed plastein was about 2000. Alkalase mediated plastein r...
