Nanoclay sorbent methods for use with dialysis
Dialysis is enhanced by using nanoclay sorbents to better absorb body wastes in a flow-through system. The nanoclay sorbents, using montmorillonite, bentonite, and other clays, absorb significantly more ammonium, phosphate, and creatinine, and the like, than conventional sorbents. The montmorillonite, the bentonite, and the other clays may be used in wearable systems, in which a dialysis fluid is circulated through a filter with the nanoclay sorbents. Waste products are absorbed by the montmorillonite, the bentonite, and the other clays and the dialysis fluid is recycled to a patient's peritoneum. Using an ion-exchange capability of the montmorillonite, the bentonite, and the other clays, waste ions in the dialysis fluid are replaced with desirable ions, such as calcium, magnesium, and bicarbonate. The nanoclay sorbents are also useful for refreshing a dialysis fluid used in hemodialysis and thus reducing a quantity of the dialysis fluid needed for the hemodialysis.

MULTILAYER STRUCTURE FOR TRANSPORTING OR STORING GAS OR FOR EXPLOITING OFFSHORE OIL DEPOSITS UNDER THE SEA
A multilayer structure for transporting or storing gas including, from the inside to the outside, at least one sealing layer and at least one composite reinforcing layer, the innermost composite reinforcing layer being welded to the outermost adjacent sealing layer, the sealing layers being a composition predominantly including at least one semi-crystalline thermoplastic polymer P1i (i=1 to n, n being the number of sealing layers), the Tm of which is less than 280 C., and at least one of said composite reinforcing layers being a fibrous material in the form of continuous fibers impregnated with a composition predominantly including at least one thermoplastic polymer P2j, (j=1 to m, m being the number of reinforcing layers), the thermoplastic polymer P2j having a Tg greater than the maximum temperature of use of the structure (Tu), with TgTu +20 C., Tu being greater than 50 C.
