We report on a continuous method for controlled electrospinning of polymeric nanofibers two-dimensional (2D) and three dimensional (3D) substrates using low voltage near-field (LV NFES). The overcomes some the drawbacks in more conventional by superelastic polymer ink formulation. viscoelastic nature our enables at very 200 V, almost an order magnitude lower than NFES, thereby reducing bending instabilities increasing control resulting jet. In one application, are freely suspended between...
This article describes the combustion behavior of combustible gases as they are released from clathrate cages a hydrate. Gas hydrates (clathrates) ice-like crystalline solids that encapsulate guest gas molecules. It has become known significant methane storehouse is in form on sea floor and arctic permafrost. There great interest this large fuel storehouse, particularly how to extract clathrates. One unique features it flammable, despite being 85% water – fiery ice. While clathrates most...
This research studies the structure of flames that use laboratory-produced methane hydrates as fuel, specifically for purpose identifying their key combustion characteristics. Combustion a hydrate involves multiple phase changes, large quantities solid clathrate transform into fuel gas, water vapor, and liquid during burning. With its unique stable energy storage capability, in are focused on potential usage an alternative source or fire safety. Considering conventional resource studying...
Natural gas hydrates in sediments can never reach thermodynamic equilibrium. Every section of any hydrate-filled reservoir is unique and resides a stationary balance that depends on many factors. Fluxes hydrocarbons from below support formation new hydrate, inflow water through fracture systems leads to hydrate dissociation. Mineral/fluid/hydrate interaction geochemistry are some the other factors determine local saturation pores. Even when using real coring it impossible reproduce...
Abstract Combustion‐driven thermophotovoltaic (TPV) systems have obtained increasing attention in recent decades, but most studies focused on developing narrowband photovoltaic cells and selective emitters. In terms of the heat source, conventional combustion configurations light gaseous fuels are extensively utilized macro‐ or meso‐scale TPV power to simplify thermal management mechanical fabrication. As far as miniaturization is concerned, however, fuelling these with liquid hydrocarbons...
