The present invention includes compositions, surface and bulk modifications, and methods of making of LiLi13Mn23O2. The tensioner assembly can have a riser conductor portion, a tension disk, a lower support structure, a plurality of ram tensioner piston rods, a cylinder deck, a plurality of hydraulic stroke cylinders, a plurality of first primary accumulators, a plurality of second primary accumulators, a plurality of first valves, a plurality of secondary accumulators, and a plurality of second valves. Furthermore, a plurality of polarization compensators and a coupler are connected directly or with a connector so as to prevent the polarization planes of the lightwaves whose wavelengths are adjoining from coinciding with each other, and preferably the polarization compensators and the coupler are connected directly or with connectors so that the polarization planes are orthogonal. The second green sheet includes a second glass including Si and B. , the plugging composition quickly thickens to form a sealing mass that is substantially impermeable to fluid in less than about 1 minute after contacting the water.
