Screening of commercial sorbents for the removal of phosphates from water and modeling by molecular simulation
(Elsevier, 2018)"Eight commercial sorbents of different origin and nature were studied in the present work for the removal of phosphate from water using synthetic solutions and a wastewater from an anodizing company. The materials included ... -
Enhancement of perchlorate removal from groundwater by cationic granular activated carbon: Effect of preparation protocol and surface properties
(Elsevier, 2018)"In order to obtain a high adsorption capacity for perchlorate, the epoxide-forming quaternary ammonium (EQA) compounds were chemically bonded onto granular activated carbon (GAC) surface by cationic reaction. The optimum ... -
Climate change in forest ecosystems: A field experiment addressing the effects of raising temperature and reduced rainfall on early life cycle stages of oaks
(Elsevier, 2018)"Higher temperatures and reduced rainfalls that are expected with the advance of climate change can impair the emergence and establishment of tree seedlings in forest ecosystems. These climatic changes can also decrease ... -
Chemical stability of superhard rhenium diboride at oxygen and moisture ambient environmental conditions prepared by mechanical milling
(The American Ceramic Society, 2018)"In this study, rhenium diboride (ReB2) was obtained by mechanosynthesis at 640 minutes of milling. The obtained ReB2 was stored at oxygen and moisture ambient environmental conditions to know the chemical stability. The ... -
Transformation process dependent magnetocaloric properties of annealed Ni50Mn18Cu7Ga25 ribbons
(Elsevier, 2017)"The properties related to magnetocaloric effect (MCE) of annealed Ni50Mn18Cu7Ga25 ribbons were studied in connection with their microstructural features and magnetostructural transformations. The differences in magnetic ... -
Large reversible magnetic entropy change in rapidly solidified Ni0.895Cr0.105MnGe1.05 melt-spun ribbons
(Elsevier, 2018)"The crystal structure, and magnetic and magnetocaloric properties of rapidly solidified Ni0.895Cr0.105MnGe1.05 melt-spun ribbons is reported. The ribbon samples crystallize into a single-phase hexagonal Ni2In-type structure ... -
Production of biodiesel from roasted chicken fat and methanol: free catalyst
(2014)"Transesterification reactions free of catalyst between roasted chicken fat with methanol were carried out in a batch reactor in order to produce biodiesel to temperatures from 120°C to 140°C. Parameters related to the ... -
