COBISS.SI-ID: 1632815The intercalated OMM/PAC nanocomposites were prepared by solvent pre-intercalation in MPA and confirmed by XRD and TEM measurements. XRD measurements show that the concentration of OMM between 1% (w/w) and 4% (w/w) in OMM/PAC/MPA dispersion has no influence on interlayer distance between the OMM platelets. On the other side rheological measurements display increase of the viscosity of OMM/PAC/MPA dispersion by increasing OMM concentration. At higher OMM concentrations non-Newtonian behavior became pronounced as a result of higher structure and lower free motion of the polymer chains. Similar behavior was observed for dried OMM/PAC composite films. Namely storage and loss modulus increase by OMM concentration in composite as a result of additional interactions between OMM nanoplatelets and polymer chains. Structure changes were also confirmed by measurements of hardness where higher OMM concentrations lead to increase in composite film hardness. Anticorrosion properties of OMM/PAC nanocomposite as a result of barrier properties ofOMMplatelets were evaluated by EIS. Results indicate that higher concentrations ofOMMlead to increase in the water absorption and consequently diminish improved barrier properties of nanocomposite. From the electrochemical impedance spectroscopy results we conclude that 1% (w/w) of OMM gives the largest improvement of anticorrosion properties in OMM/PAC nanocomposite.
F.04 Increase of the technological level
COBISS.SI-ID: 271394816The paper focuses on the integration of renewable energy sources (RES) within municipal energy systems. The concept of Locally-Integrated Energy Sectors (LIES) is one of available approaches and is known as an extension of the Total Site methodology to larger geographical areas and includes besides industrial energy users also other sectors, such as service, household, agriculture, transport and public sectors. The proposed LIES concept including RES is intended to encourage connections among end users from various sectors, and support integration of RES.
F.12 Improvements to an existing service
COBISS.SI-ID: 24277048The current contribution builds upon the locally-integrated energy sectors (LIES) concept. The LIES concept (Perry et al., 2008) extended the TS methodology (Dhole and Linnhoff, 1993) developed initially for industrial complexes mainly. LIES (Varbanov and Klemeš, 2011) offer a further extension of Total Site (TS) concept to accommodate collaboration between industry and local communities. This concept can be especially attractive for the municipalities abundant with natural resources. Recent research leads towards integration of energy users and energy producers over larger geographical areaup to regional scale. The design optimisation is investigated for local and regional energy supply at municipal and higher level to accelerate the useof renewable resources within rural municipalities. The demand levels and patterns of the involved energy user types are described, followed by the selection of promising renewable and fossil resources. The variability of renewables makes it necessary to accommodate varying availability by optimal demand side management, appropriate clustering of energy sources and sinks, aswell as using energy storage.
