In situ Al-27 NMR kinetic investigation of zeolite A crystallization
(Elsevier Science Bv, Amsterdam, 2014)
In this study, in situ Al-27 NMR spectroscopy was used to gain detailed information concerning kinetics of zeolite A crystallization. Changes of relative intensity and width at half-height of NMR lines at 59 ppm ascribed ...
An exergy composite curves approach for the design of optimum multi-pressure organic Rankine cycle processes
(Pergamon-Elsevier Science Ltd, Oxford, 2014)
This work adopts the (ECCs) under bar (exergy composite curves) approach to explore the potential for ORC (organic Rankine cycle) process improvements. The method is used to explore different ORC configurations supported ...
Review of biodiesel synthesis from waste oil under elevated pressure and temperature: Phase equilibrium, reaction kinetics, process design and techno-economic study
(Pergamon-Elsevier Science Ltd, Oxford, 2014)
The synthesis of biodiesel under elevated pressure and temperature could be promising technology which could result in sustainable biodiesel production, from renewable and waste streams like waste oil or used frying oil, ...
Metal | polypyrrole battery with the air regenerated positive electrode
(Elsevier Science Bv, Amsterdam, 2014)
Recharge characteristics of the battery based on the electrochemically synthesized polypyrrole cathode and aluminum, zinc, or magnesium anode in 2 M NH4Cl are investigated. It is shown that polypyrrole electrode can be ...
Trace analysis of selected hormones and sterols in river sediments by liquid chromatography-atmospheric pressure chemical ionization-tandem mass spectrometry
(Elsevier, Amsterdam, 2014)
In this paper, development and optimization of new LC-MS method for determination of twenty selected hormones, human/animal and plant sterols in river sediments were described. Sediment samples were prepared using ultrasonic ...
Heat transfer between a packed bed and a larger immersed spherical particle
(Pergamon-Elsevier Science Ltd, Oxford, 2014)
In this paper, heat transfer coefficients between the hot packed beds of particles and the larger cold immersed sphere were experimentally determined. The packed beds consisted of mono-sized spherical glass particles of ...
The first 1000 cultured species of the human gastrointestinal microbiota
(Oxford Univ Press, Oxford, 2014)
The microorganisms that inhabit the human gastrointestinal tract comprise a complex ecosystem with functions that significantly contribute to our systemic metabolism and have an impact on health and disease. In line with ...
Synergistic anti-biofouling effect of Ag-exchanged zeolite and D-Tyrosine on PVC composite against the clinical isolate of Acinetobacter baumannii
(Taylor & Francis Ltd, Abingdon, 2014)
Due to their susceptibility to bacterial biofilm formation, commercial tubes for medical use are one of the main sources of hospital infections with Acinetobacter baumannii. The anti-biofouling activity of novel composites ...
Potentials and status of biogas as energy source in the Republic of Serbia
(Pergamon-Elsevier Science Ltd, Oxford, 2014)
Biogas is a sustainable and renewable energy source that can provide green energy, a better environment and new jobs. The aim of this paper is to present potentials for biogas production in the Republic of Serbia from ...
Transient thermal response of textile fabrics made of natural and regenerated cellulose fibers
(Elsevier Sci Ltd, Oxford, 2014)
The thermal parameters that describe the transient response of cellulose textile fabrics due to the changes in physiological and environmental conditions were analyzed. Starting from the specific heat of the knitted fabrics ...
