Biodiesel production: The problems in software design at supercritical and subcritical conditions
(Supercritical Fluids, 2011)
A large interest in research as well as dramatically increased number of scientific papers covering this topic evidently exists. This chapter covers the literature review of biodiesel production under specific conditions ...
Macroporous and non-porous amino-functionalized glycidyl methacrylate based copolymers for hexavalent chromium sorption
(Chromium: Environmental, Medical and Materials Studies, 2011)
Two porous samples and one non-porous sample of crosslinked poly(glycidyl methacrylate-co-ethylene glycol dimethacrylate) [abbreviated PGME] were synthesized by suspension copolymerization and functionalized by ring-opening ...
Thermoplastic Copolyester Elastomers
(Handbook of Engineering and Speciality Thermoplastics: Polyethers and Polyesters, 2011)
In this chapter the preparation, structure and properties of thermoplastic copolyester elastomers, TPEE, are presented. TPEEs are multiblock copolymers built up from so-called short crystallizable hard segments and long ...
Chitin and chitosan from microorganisms
(Chitin, Chitosan, Oligosaccharides and Their Derivatives: Biological Activities and Applications, 2010)
Today, a major concern about the use of crustacean chitin/chitosan in the pharmaceutical and biomedical field is still the molecular variability of a natural product, which results in a wide unpredictable range of ...
Solid acids as catalysts for biodiesel synthesis
(Heterogeneous Catalysts: Design, Applications and Research Insights, 2016)
Increased environmental concern and awareness of limited reserves of fossil fuels gave a great importance to alternative and renewable energy sources over the past couple decades. An excellent substitute for mineral diesel ...
Evaluation of Periodic Processes
(Elsevier, 2013)
Image analysis technique for evaluating damage evolution and predicting mechanical strength of concrete structures under corrosion conditions
(Advances in Image Analysis Research, 2014)
The degradation of concrete structures, which progresses as time passes, is caused by external factors such as chemical, physical and mechanical interferences. In the case of chemical deterioration, various ions penetrate ...
Supercritical extraction of phloroglucinols from St. John's wort (Hypericum Perforatum L.) - Process optimization, mathematical modeling and antimicrobial activity
(Phytochemicals: Occurrence in Nature, Health Effects and Antioxidant Properties, 2013)
St. John's Wort (Hypericum perforatum L.) has been widely used as an anti-inflammatory and healing agent in traditional medicine. Some para-pharmaceutical products, prepared from the extract of St. John's Wort, are frequently ...
Approaches to mathematical modeling of tissue engineering systems
(Cell and Tissue Engineering, 2012)
Tissue engineering (TE) is one of the new strategies aiming to address the problem of tissue failure by in vitro cultivation of functional tissue equivalents (please see the Chapter 1). Ideally, engineered tissues can serve ...
Influence of chemical stress on sulfur-polymer composite structure
(New Developments in Polymer Composites Research, 2013)
Sulfur- polymer composites are high performance thermoplastic materials made of mineral aggregate, filler, and modified sulfur binder, instead of cement and water as in ordinary Portland cement- based composites at ...
