Copper is probably one of the most important metal used in the broad range of electronic applications. It has been developed for many decades, and so it is very hard to make any further advances in its electrical and thermal performance by simply changing the manufacture to even more oxygen-free conditions. Carbon nanotubes (CNTs) due to their excellent electrical, thermal and mechanical properties seem like an ideal component to produce Cu-CNT composites of superior electrochemical performance. In this report we present whether Cu-CNT contact has a beneficial influence for manufacturing of a new type of carbon-based supercapacitor with embedded copper particles. The prepared electrode material was examined in symmetric cell configuration. The specific capacity and cyclability of composite were compared to parent CNT and oxidized CNT.

New type of commercial plaster which is not well known in the market is investigated in this paper. It is a new product delivered from Turkey, contains 80% of perlit, the binder is unknown and according to the producer it is some type of polymer. According to the producer’s data, the open porosity is 80% and the main advantages are good thermal and mechanical properties. The data in the technical data sheet are not complete, some important information is missing, therefore the basic physical, mechanical, thermal and hygric properties were studied in this paper. Moisture diffusivity, thermal conductivity and specific heat capacity are determined as a function of moisture content. Obtained data were compared with ordinary lime-cement plaster. The results can be further utilized in the computer simulation for service life assessment studies.

A new type of porous brick is proposed. Sawdust is initially well mixed with wet clay in order to create voids inside the brick during the firing process. The voids will enhance the total performance of the brick due to the reduction of its density and thermal conductivity and a minor reduction of its compressive stress. All these properties have been measured experimentally and good performance has been obtained. Although a minor reduction in compressive stress has been observed with increased porosity, this property has still been larger than that of the common used hollow brick. Data obtained by this work lead to a new type of effective brick having a good performance with no possibility that mortar enters inside the holes which is the case with the common used hollow bricks. The mortar has a determent effect on thermal properties of the wall since it has some higher thermal conductivity and density than that of brick which increases the wall overall density and thermal conductivity of the wall.

ABSTRACT The rubber industry is facing strong challenges in recent times because of imposed stringent standards on the performance of a product under adverse thermal and chemical applications. The choice of proper elastomer plays a significant role in imparting useful product performance. A new type of acrylic rubber with a fluoroacrylate cure site monomer was developed. Structural characterization, such as Fourier-transform infrared spectroscopy and nuclear magnetic resonance (NMR), suggested the presence of four different monomer units. Two-dimensional NMR spectroscopy analysis was also performed to support the assessment of the resonance peaks of coupled nuclei spins in the terpolymer. The newly developed acrylic rubber exhibited superior thermal and mechanical properties. Hexamethylenediamine carbamate in combination with zinc oxide (ZnO) was used as the curing package for the new elastomer. ZnO acts as an acid scavenger to avoid the micro-void formation. The new elastomer with a higher number of cross-link junctions resulted in superior mechanical and thermal properties as well as swelling resistance of the vulcanizate both with and without carbon black.
