Abstract: A condenser module of a heating, ventilation, and/or air conditioning (HVAC) system includes a first slab having a first plurality of tubes configured to receive a refrigerant from a compressor of the HVAC system. The first plurality of tubes is arrayed along a first dimension of the first slab. The condenser module also includes a second slab that has a second plurality of tubes configured to receive the refrigerant from the compressor. The second plurality of tubes is arrayed along a second dimension of the second slab, the second slab is oriented at an acute angle relative to the first slab, and the second dimension is greater than the first dimension.

Abstract: A conductive composition for a secondary battery, a slurry comprising the same, an electrode comprising the same and a method of preparing the conductive composition are provided. The conductive composition comprises a polymeric material, a carbon nanomaterial and an anionic stabilizing agent. The polymeric material comprises a copolymer comprising a structural unit derived from an acid group-containing monomer and a structural unit derived from a polar group-containing monomer. The conductive composition exhibits an improved stability and dispersibility in water. In addition, battery cells comprising a cathode prepared using the conductive composition disclosed herein exhibit impressive electrochemical performances.

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.
