Resource recovery of animal bones: Study on sorptive properties and mechanism for Sr2+ ions
(Elsevier, 2010)
The interaction between Sr2+ ions and variously treated animal bones was studied from the aspect of Sr-90 isotope immobilization from the contaminated effluents. As a source of biogenic, poorly-crystalline apatite, bone ...
Kinetics of Internal Oxidation in Ag-6Sn-2In-1Te-0.2Ni and Ag-6Sn-0.6Cu-1Bi-0.2Ni Type Alloys
(Korean Inst Metals Materials, Seoul, 2012)
Internal oxidation process was followed in Ag-6Sn-2In-1Te-0.2Ni and Ag-6Sn-0.6Cu-1Bi-0.2Ni alloy types in free air and oxygen at 650 degrees C and 680 degrees C. It was found that the Cu and Bi bearing alloy had a higher ...
Kinetic model of lipase-catalyzed conversion of ascorbic acid and oleic acid to liposoluble vitamin C ester
(Elsevier Science Sa, Lausanne, 2013)
The kinetics of L-ascorbyl oleate synthesis catalyzed by immobilized lipase from Candida antarctica in acetone was investigated. Significant inhibition of synthesis with an excess of ascorbic acid was observed. Experimental ...
Core-shell structured tungsten-tungsten carbide as a Pt catalyst support and its activity for methanol electrooxidation
(Pergamon-Elsevier Science Ltd, Oxford, 2012)
Tungsten carbide was synthesized by calcination of carbon cryogel containing tungsten in a form of metatungstate. Characterization by X-ray diffraction and transmission electron microscopy indicated core-shell structure ...
Bucket wheel excavator Integrity assessment of the bucket wheel boom tie-rod welded joint
(Pergamon-Elsevier Science Ltd, Oxford, 2011)
The bucket wheel boom tie-rods are vital structural parts of the bucket wheel excavators (BWE) Their failures inevitably cause BWE collapse and are followed among other things by a substantial financial loss (millions of ...
Optimization of the production process through response surface method: Bricks made of loess
(Elsevier, 2013)
Loess clays are commonly used to produce bricks. Heavy clays, taken at location near Zrenjanin, Serbia, are used as a representative raw material in this study. The sample, containing about 28% of clay sized particles, is ...
Heteroatom-doped mesoporous carbons as efficient adsorbents for removal of dimethoate and omethoate from water
(Royal Society of Chemistry, 2016)
Extensive use of organophosphate pesticides (OPs) invokes development of efficient procedures for their removal from the environment. By introducing low levels ( LT 1 at%) of B, N or P into the structure of mesoporous ...
Transparent PMMA/silica nanocomposites containing silica nanoparticles coating under supercritical conditions
(Elsevier Science Sa, Lausanne, 2013)
This work reports the preparation of PMMA/silica nanocomposites with high optical transparency and enhanced mechanical properties using a melt compounding method. The surface of SiO2 particles was modified with a ...
Ductile fracture of pipe-ring notched bend specimens - Micromechanical analysis
(Pergamon-Elsevier Science Ltd, Oxford, 2017)
Integrity of pipes is typically assessed by testing fracture mechanics specimens, such as compact tensile (CT) or single-edge notched bending (SENB). However, for some pipe dimensions it is not easy or possible to fabricate ...
New Approach: Waste Materials as Sorbents for Arsenic Removal from Water
(Journal of Environmental Engineering, 2010)
The sorption of inorganic arsenic species (arsenite and arsenate) from aqueous solutions onto steel-mill waste and waste filter sand, under neutral conditions, was investigated in this study. Additionally, the steel-mill ...
