The influence of fluorine doping on the structural and electrical properties of the LiFePO4 powder
(Elsevier, 2017)
Low intrinsic electronic conductivity is the main disadvantage of LiFePO4 when used as a cathode material in lithium ion batteries. The paper offers experimental proofs of the theoretical prediction that fluorine doping ...
Fluorescence, thermal and mechanical properties of PMMA-CdSe QD film
(Natl Inst Optoelectronics, Bucharest-Magurele, 2017)
In the present paper an effort has been made to investigate processing and characterization of composite poly (methyl methacrylate)-cadmium selenide (PMMA-CdSe). Thin films of pure PMMA and composites with 0.06 % wt. CdSe ...
Separation of phytochemicals from Helichrysum italicum: An analysis of different isolation techniques and biological activity of prepared extracts
(Pergamon-Elsevier Science Ltd, Oxford, 2017)
Helichrysum italicum presents a valuable source of natural bioactive compounds. In this work, a literature review of terpenes, phenolic compounds, and other less common phytochemicals from H. italicum with regard to ...
The photocatalytic degradation of carbofuran and Furadan 35-ST: the influence of inert ingredients
(Springer Heidelberg, Heidelberg, 2017)
A comparative study on photocatalytic degradation of the pesticide carbofuran and its commercial product Furadan 35-ST in an aqueous suspension of ZnO, irradiated by long-wave light (315-400 nm), is presented in this study. ...
Matrix resistance stress: A key parameter for immobilized cell growth regulation
(Elsevier Sci Ltd, Oxford, 2017)
Microenvironmentally restricted yeast cell growth within Ca-alginate beads with and without entrapped gas bubbles was considered based on experimental data. Cell growth dynamics was described by (1) the dimensionless cell ...
Nanomechanical and anti-stabbing properties of Kolon fabric composites reinforced with hybrid nanoparticles
(Elsevier Sci Ltd, Oxford, 2017)
In this study carbon nanotubes (CNT) and silica nanoparticles (SiO2) were added to enhance the dynamic mechanical and anti-stabbing properties of the polyurethaneip-aramid multiaxial fabric (Kolon fabric) composites for ...
Targeting and Design of Organic Rankine Cycle Systems for Multiple Heat Sources with Simultaneous Working Fluid Selection
(Elsevier Science Bv, Amsterdam, 2017)
We propose a systematic model for the optimum design of Organic Rankine Cycles (ORC) used for power generation from multiple heat sources available at different temperatures. The model enables the automated generation of ...
Heat-Affected Zone as Critical Location in Pressure Equipment
(Springer-Verlag Berlin, Berlin, 2017)
The majority of pressure equipment is made from joining by welding parts or sub-assemblies. Welded structure should be produced by spending minimum of cost, assuring in the same time required function and safety. By proper ...
Nanoscale zerovalent iron (nZVI) supported by natural and acid-activated sepiolites: the effect of the nZVI/support ratio on the composite properties and Cd2+ adsorption
(Springer Heidelberg, Heidelberg, 2017)
Natural (SEP) and partially acid-activated (AAS) sepiolites were used to prepare composites with nanoscale zerovalent iron (nZVI) at different (SEP or AAS)/nZVI ratios in order to achieve the best nZVI dispersibility and ...
Experimental Investigation and Modeling of Thermophysical Properties of Pure Methyl and Ethyl Esters at High Pressures
(Amer Chemical Soc, Washington, 2017)
Densities, speeds of sound, and refractive indices of methyl laurate, ethyl laurate, ethyl myristate, and ethyl oleate in the temperature range 288.15-343.15 K and viscosities from 288.15 to 373.15 K were measured at ...
