2010/9/4When it comes to high R walls, the most cost effective option in most areas is a double 2x4 wall with a total thickness of about 12 inches, insulated with dense packed cellulose. In areas with very high labor costs, some builders claim that it is less expensive to build a 2x6 wall covered on the exterior with 2 or 3 inches of polyisocyanurate foam.

First principle calculations were carried out to simulate the three decomposition gases (SO2, SOF2, and SO2F2) of sulfur hexafluoride (SF6) on Ga doped MoS2 (Ga MoS2) monolayer. Based on density functional theory (DFT), pure MoS2 and multiple gas molecules (SF6, SO2, SOF2, and SO2F2) were built and optimized to the most stable structure. Four types of Ga doped positions were considered and it
