Volumetric properties of the binary methanol plus chloroform and ternary methanol plus chloroform plus benzene mixtures at (288.15, 293.15, 298.15, 303.15, 308.15, and 313.15) K
(Amer Chemical Soc, Washington, 2007)
Densities rho of the ternary system of methanol + chloroform + benzene and binary mixture of methanol + chloroform have been measured at six temperatures (288.15, 293.15, 298.15, 303.15, 308.15, and 313.15) K and atmospheric ...
Phase-transformation kinetics in triphasic cordierite gel
(Cambridge Univ Press, New York, 2001)
A triphasic cordierite-type gel was prepared from silica sol, boehmite sol, and an aqueous solution of Mg(NO3)(2). 6H(2)O. The silica sol was obtained from water glass by the ion exchange method, while boehmite sol was ...
Life Cycle Energy Assessment of biohydrogen production via biogas steam reforming: Case study of biogas plant on a farm in Serbia
(International Journal of Hydrogen Energy, 2021)
The aim of this paper is to demonstrate and to quantify energy flows in a life cycle of biogas to biohydrogen production, starting from feedstock materials via anaerobic digestion, biogas upgrading, biohydrogen production, ...
Direct hemp cellulose dissolution in N-Methylmorpoline-N-Oxide
(Taylor & Francis Inc, Philadelphia, 2007)
The increased production of bast fibres (especially hemp fibres) brought about an increase in the amount of waste, namely shive (hemp stalks) and short fibres. This waste presents a potential significant source of high ...
A fracture mechanics approach to thermal shock investigation in alumina-based refractory
(9th International Conference on Multiscale and Functionally Graded Materials, FGM IX, 2008)
The thermal shock behavior of large grain size, alumina-based refractories was investigated experimentally using a standard water quench test. A mathematical model was employed to simulate the thermal stability behavior. ...
Microwave-assisted immobilization of lipase from Candida rugosa on Eupergit (R) supports
(Wiley, Hoboken, 2009)
BACKGROUND: Immobilization of lipase (triacylglycerol acylhydrolase EC 3.1.1.3) from Candida rugosa on Eupergite (R) C and Eupergit (R) C 250L was performed under microwave irradiation in order to reduce immobilization ...
Nonisothermal melt-crystallization kinetics of hydroxyapatite-filled poly(3-hydroxybutyrate) composites
(Wiley, Hoboken, 2006)
The knowledge of biomedical implants ranging from drug delivery devices to tissue engineering and based on bioresorbable polymer composites is increasing, but the study of the crystallization kinetics of these kinds of ...
The particle distribution functions and applications
(Natl Inst Optoelectronics, Bucharest-Magurele, 2006)
The new generalized logarithmic equation defined by four parameters, called LG4, was formulated and proposed for describing particle size and shape distributions. For special choice of the parameters the LG4 was reduced ...
Carbon-13 substituent chemical shifts in N-1-p-substituted phenyl-5-methyl-4-carboxy uracils
(Elsevier Science Bv, Amsterdam, 2007)
The C-13 NMR chemical shifts of seven N-1-p-substituted phenyl-5-methyl-4-carboxy uracils have been measured in deuterated dimethyl sulfoxide (DMSO-d sigma). The correlation analysis for the substituent-induced chemical ...
Influence of composition of the magnetic composite coating on the performance of the optical fiber magnetic field sensing element
(Natl Inst Optoelectronics, Bucharest-Magurele, 2007)
The optical fiber magnetic sensing element (OFMSE) based on the optical fiber coated with composite coating polymer-magnetic powder has been already introduced in magnetic field sensing. In this research, the rapid quenched ...
