Abstract: The present disclosure provides a thermoelectric generator and methods for fabricating the same. The semiconductor legs and electrodes of the thermoelectric generator are embedded in one or more flexible polymer matrices providing protection to the semiconductor legs and electrodes to maintain good electric contacts among them during bending. Thus, the output power of the thermoelectric generator can be substantially retained even after a large number of bending cycles.

Abstract: Disclosed is an environmentally friendly recycling process for expanded polystyrene (EPS) wastes using dissolution process and supercritical CO2 extraction process. The recycling process may enable condensing an expanded polystyrene (EPS) by dissolving the EPS into a solvent and one or more additives thereby obtaining an expanded polystyrene (EPS) solution. The recycling process may further enable purifying the EPS solution using at least one of a filtration process and a separation process in order to obtain a purified expanded polystyrene (EPS) solution. Further, the recycling process may further enable extracting the polystyrene from the solvent in the purified expanded polystyrene (EPS) solution using a supercritical CO2 extraction method in order to obtain a recycled polystyrene. The recycling process enables in significant reduction of the volume of EPS thereby saving the logistical cost as well as facilitating increase in quantity, quality and purity of the recycled polystyrene.
