The natural bentonite and bentonite/iron oxide composite were used as sorbents of Cu(II). Their sorption properties were examined under the different conditions such as pH of the solution, initial metal ion concentration. The bentonite removed 71 % Cu(II) while composite 90 %. Their maximum adsorption capacities were 34.1 and 44.4 mg Cu(II) g -1, r...

Base isolation systems are among the most successful and widely applied methods of mitigating structural vibration and damage during seismic events. These systems have been installed in numerous full-scale structures all around. There are three principal types of base isolators: Lead Rubber Bearing (LRB), High Damping Rubber Bearing (HDRB), and Fri...
