AB  - The consequence of drastic reduction in fossil fuel reserves has forced the
scientific community to find and develop new ways to exploit renewable resources and
optimize the process of polymer materials production. The aim is to obtain applicable
polymer whose complete life cycle is set in ecological framework. Poly(lactide) (PLA)
meets these requirements as biodegradable polyester whose monomer is derived from the
plant feedstock containing carbohydrates. PLA could be prepared using the different
synthesis routes, but from the point of energy saving, as well as environmental protection,
the microwave synthesis of PLA is the best solution. In this work, poly(L-lactide) were
synthesized in microwave reactor. Reaction time was varied, while the other parameters of
the synthesis were constant. The structures of obtained polymers were confirmed by Fourier
– transform infrared spectroscopy (FT-IR). For determination of molar masses of poly(Llactide) samples, the gel permeation chromatography (GPC) was applied. Thermal
properties were investigated by differential scanning calorimetry (DSC).

AB  - Phenol is a major pollutant in the wastewater because of its presence in the effluent of major processing and refining plants. It has severe effect on human being, both short term and long term. Various methods are used for removal of the phenol from wastewater such as adsorption, photodecomposition, volatilization and other various biological and non-biological methods. In the present study attempt is done to present the survey of the research on the phenol removal by various methods. The methods such as polymerization, electrocoagulation, extraction, photodecomposition, advanced oxidation and ion exchange were used effectively by various investigators. These methods are reported to be efficient for the phenol removal. Suitable method for phenol removal can be selected based on availability of the material, extent of separation required and properties of phenolic effluent.
AB  - Fenol je jedan od glavnih polutanata u otpadnoj industrijskoj vodi. Utiče na zdravlje ljidi i taj uticaj se ispoljava kako posle kraćeg tako i posle dužeg prisustva. Za uklanjanje fenola iz otpadne vode koriste se metode kao što su adsorpcija, fotorazgradnja, isparavanje (volatilizacija) kao i biološke i nebiološke metode. U ovom radu daje se prikaz istraživanja o uklanjanju fenola različitim metodama kao što su polimerizacija, elektrokoagulacija, fotorazgradnja, unapređena oksidacija i jonska izmena. Izbor metode za uklanjanje fenola može biti učinjen na osnovu raspoloživog
materijala, zahtevanog intenziteta prečišćavanja i osobina fenolnog efluenta.

AB  - The parameters of foam preparation, such as addition of fillers, have a significant effect on the properties of polyurethane foams. The goal of this work was to study the effect of the cement addition on the thermo-mechanical properties of rigid polyurethane foams. Isocyanate component was based on polymeric diphenylmethane diisocyanate, and polyol component was polyether type, with addition of castor oil as polyol. It was estimated that the addition of cement increased the values of foam compressive strength and permanent deformation. Compressive strength increased even more than 90% with 20 wt% of cement. Further increase of the cement loading deteriorates the mechanical properties of foamed material because it distorts cellular structures of obtained materials. Addition of cement increased the value of the glass transition temperature of polyurethane foam. The highest increase in the value of glass transition temperature, for 7.5ºC, was achieved by the addition of 20 wt% of cement.

AB  - Using cheap renewable raw materials such as lignocellulosic feedstock for hydrogen production by fermentation has great significance and potential to give a major contribution to future clean energy. Using hydrogen as a promising alternative energy source for fossil fuels is increasing. Hydrogen is clean, renewable high energy fuel that does not contribute the greenhouse gas effect. The main challenges in developing hydrogen production are the low hydrogen yields due to poor efficiency on a direct microbial assimilation of cellulosic materials. From this reason, in the world today occurs considerable research efforts to improve the pretreatment and hydrolysis of lignocellulosic materials. The development of effective cellulase enzymes, optimization and improvement of the fermentation process as well as engineering approaches to application processes are the basis of the increased popularity of the lignocellulosic feedstock. Research on the genomic combined with genetic engineering offers a wide range of opportunities to improve the performance of using cellulosic raw materials in the production of hydrogen. This paper provides an overview of key technologies in the world today that research and development biohydrogen from lignocellulosic feedstocks.
