WebThe p660 form absorbs red light and is converted to the p73o form believed to induce a biological response. The P 7 3 0 form absorbs far-red and is converted to the inactive P 6 6 0 form. The P 7 3 0 form kept in the dark reverts to the P 6 6 0 form (Hendricks 1959). The action spectrum for photolability is seen in the lower part of Figure 9.
WebOct 27, 2024 · Double diaphragm forming (DDF), a specific type of DF, employs a secondary flexible membrane between which the laminate is encapsulated. The chamber below the diaphragm is then evacuated and atmospheric pressure pushes the diaphragm downwards, forming the laminate onto the mould surface.
