They twist on the time axis making this a relativistic effect at the opposite end of the spectrum from an event horizon. I humbly submit that the engine for catalytic action is a Casimir time detour where reactants "do their time" before returning from the cavity or outcropping of Casimir geometry to our plane.

No thermodynamic anomalies appear even when superconducting, e.g., MgB2). The layers don't form mirrored etalons. If you're feeling clean and wholesome, science has the cure - casimatter! A 70 nm aluminum layer, 2.7 g/cm^3, reflects 93% (99% of theoretical) between 100 and 120 nm. MgF2, 3.177 g/cm^3 and RI = 1.63 at 121 nm, has 80% transmittance at 115 nm. LiF, 2.639 g/cm^3 and RI = 1.777 goes to 110 nm. Aluminum's coefficient of thermal expansion, 23.1 ppm/K, is matched by 60:40 MgF2:LiF alloy, RI = 1.628 at 121 nm. Spin a flat wide deposition torus over alternating sectors of magnetron sputtered Al metal and 60:40 MgF2:LiF alloy to lay down an endless alternate bifilar spiral deposit of 70 nm Al and 37 nm fluoride alloy to half-wave cancel a 120 nm optical pathlength. Cool, cut out pieces of casimatter: average density 2.79 gm/cm^3 of which 37 wt-% is ZPF-depleted fluoride alloy. Examine casimatter cleverly.
