The invention provides an organic-inorganic porous membrane which includes metal organic silica nano-particles impregnated in a polymer. The systems and methods utilize a coupling prism having a coupling angle \u03b1 having a maximum coupling angle \u03b1max at which total internal reflection occurs. The continuous blade includes a first portion positioned in the cut zone for performing a cutting operation and a second portion positioned outside of the cut zone. The bus control module monitors and controls power distribution within the system.
