Isosorbide-derived epoxies and methods of making same are disclosed. The projection system includes, a docking device integrated with a surface of the vehicle, wherein the docking device is in electrical communication with at least one secondary device. The method also includes receiving source text content to display in the user interface. 18 and satisfies dielectric constant anisotropy \u0394\u03b5 of 0<\u0394\u03b5<13 and twist elasticity modulus K22 of K22>3. The flow path of the working fluid is not interrupted or influenced, so the heat transfer efficiency can be maintained, which overcomes the decrement of the heat transfer efficiency of a bent heat pipe in the prior art.
