Smart hydrogels for pharmaceutical applications
(Novel Approaches for Drug Delivery, 2016)
The latest development in the field of smart hydrogels application as drugs carriers is shown in this chapter. Hydrogels are three-dimensional polymer network consisting of at least one hydrophilic monomer. They are insoluble ...
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 ...
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 ...
Possibilities of improving the bioethanol production from cornmeal by yeast saccharomyces cerevisiae var. ellipsoideus
(Causes, Impacts and Solutions to Global Warming, 2013)
Bioethanol has become one of the most promising biofuels today. In Serbia, the most suitable and available raw materials are conventional starch-based energy crops such as corn and triticale. Bioethanol production by ...
Erythrocyte membranes: Unique constituent of biological/hybri drug delivery systems
(Erythrocytes: Structure, Functions and Clinical Aspects, 2019)
For many decades, the red blood cell membranes were in focus of research interest solely as a model system for investigation into the various membrane-related phenomena, composition/organization or membrane transport ...
Biodiesel Fuel Production by Enzymatic Transesterification of Oils: Recent Trends, Challenges and Future Perspectives
(IntechOpen, 2011)
Liquid fuels have been used for many years as the most dominant and basic fuel for motor
engines. However, declining fossil fuel resources as well as the tendency for developing
new renewable biofuels have shifted the ...
Micro and nanoscale morphology characterization of compatibilized polymer blends by microscopy
(Compatibilization of Polymer Blends: Micro and Nano Scale Phase Morphologies, Interphase Characteriz, 2019)
Polymer blends are mostly immiscible at a molecular level due to their large molecular mass. Therefore, the study of the way how two polymers are mixed together is of great interest. The properties of the polymer blend are ...
Vegetable oil as a feedstock for biodiesel synthesis
(Vegetable Oil: Properties, Uses and Benefits, 2016)
Limited reserves of fossil fuels as well as the growing concern for the environment, has led to a worldwide search for renewable energy sources, among which biodiesel, a mixture of fatty acid methyl esters (FAME), is one ...
Effect of the Thermo-Mechanical Treatment on IGC Susceptibility of AA 5083 Alloy
(Light Metals 2014, 2014)
This work reports on the effect of thermo-mechanical treatment on IGC susceptibility of the AA 5083 alloy. Specimens underwent varied amount of cold work and final annealing was conducted at 240°C. Extent of the cold work ...
Health hazards of heavy metal pollution
(Nova Science Publishers, Inc., 2016)
The global population growth, urbanization and the increased energy demand led to serious changes in the environment. Numerous anthropogenic activities release a variety of toxic and potentially toxic pollutants into the ...
