Pollution characteristics and potential ecological risk assessment of heavy metals in river sediments based on calculation of pollution indices
(Nova Science Publishers, Inc., 2015)
The presented study was carried out in order to evaluate risk assessment of selected heavy metals (Cd, Cu, Mn, Cr, Ni, Pb, Zn, Co and V) in river sediments in Serbia. The purpose of this chapter is to describe a new approach ...
The molecular properties of some diesel fuel components and their biodegradation
(Nova Science Publishers, Inc., 2013)
Alkylated polycyclic aromatic hydrocarbons (PAHs) are especially important whenuncombusted fuels are of concern. Bioremediation has become one of the most rapidlydeveloping techniques for cleaning up contaminated soil and ...
Synthesis and characterization of polystyrene based nanocomposites
(Nova Science Publishers, Inc., 2014)
Polystyrene, one of the most important material in the modern plastic industry and one of the major synthetic polymer in use today, offers an extremely broad range of applications, due to its good physical properties and ...
Evaluation of the possibility of using normalization with cobalt in detection of anthropogenic heavy metals in sediments
(Nova Science Publishers, Inc., 2015)
Geochemical normalization with conservative elements has been effectively used for assessing the enrichment of metal pollutants and distinguishing their natural and anthropogenic sources. Without correcting for textural ...
The application of density functional theory to calculation of properties of environmentally important species di- and trimethylnaphthalenes
(Nova Science Publishers, Inc., 2013)
Alkylated naphthalenes are persistent environmental pollutants but there is still littleinformation on their characteristics. In this chapter we present the application of DensityFunctional Theory (DFT) methods for obtaining ...
Poly(Ethylene Terephthalate): Synthesis and physicochemical properties
(Nova Science Publishers, Inc., 2017)
This chapter summarizes the synthesis and physicochemical properties of thermoplastic polyester, poly(ethylene terephthalate) (PET). PET, along with poly(butylene terephthalate) (PBT) is an aliphaticaromatic and semicrystalline ...
The synthesis of a sulfur-polymer matrix composite and morphological analysis of the samples in extreme conditions
(Nova Science Publishers, Inc., 2018)
Polymers had a great influence in the development of practical applications of materials and among the extensive variety of these compounds, organic polymers had a crucial role. Having in mind their wide practical application ...
Charophytes (Charales) of lake Skadar/Shkodra: Ecology and distribution
(Springer Verlag, 2018)
Charophytes or stoneworts (Charales, Characeae) are submerged green macroscopic algae of great importance for the environmental and economic sustainability of the aquatic ecosystem of Lake Skadar/Shkodra. In the course of ...
Poly(dimethylsiloxane) modified polymers: Synthesis, structure and physical properties
(Nova Science, 2018)
Poly(dimethylsiloxane)s (PDMS) have one of the lowest values of glass transition temperature among synthetic polymers, and indicate lowtemperature flexibility, excellent thermal, thermo-oxidative and ultraviolet stability, ...
Design of multi-pressure organic rankine cycles for waste heat recovery in site utility systems
(Elsevier, 2014)
This work addresses the design of Organic Rankine Cycle (ORC) processes used for power generation from low-grade heat available in site utility systems. The Exergy Composite Curves approach is used within a systemic ...
