One-Step Fabrication of Superomniphobic Pvdf-HFPSiO2Membrane for Long-Term CO2 Absorption inMembrane Gas Absorption System
Abstract: Membrane pore wetting is one of the major challenges for membrane gas absorption, especially when low surface tension liquid absorbents such as amine absorbents are utilized. To minimize diffusion resistance across the membrane, maintaining a non-wetted operating mode in membrane gas absorption is crucial. In this study, a superomniphobic polyvinylidene fluoride-cohexafluoropropylene membrane was fabricated by adding silica nanoparticles (SiO2) in an ethanol coagulation bath through non-solvent-induced phase separation. The surface …

Laws of Thermodynamics Challenge Greenhouse-Gas and CLIMATE- change Hypotheses
Abstract: The greenhouse-gas hypothesis (GGH), i.e., CO2 is the cause of global warming by ~1K from ~1950-2023, is popularly believed to be established scientific truth. It is generally assumed that heat emissions from global fuel combustion are, by comparison, negligible. An application of the Hess-Gibbs 1st law of thermodynamics, however, shows that the enthalpy (H) output from yearly fossil fuel consumption is seven times greater than the H- increase of hypothetical …
