A method of repairing a defect in an annulus fibrosus of an intervertebral disc, without excising the entire nucleus pulposus of the disc. The method includes inserting an introducer needle through the annulus fibrosus by puncturing the annulus fibrosus with the introducer needle, injecting an in situ curable, bio-compatible polymerizable or polymeric material composition into the disc through the introducer needle directly or indirectly so that the in situ curable composition contacts a defect in the annulus fibrosus; and curing said material in situ.

An electrochemical device comprising alternating layers of positive and negative electrodes separated from each other by separator layers. The electrode layers extend beyond the periphery of the separator layers providing superior contact between the electrodes and battery terminals, eliminating the need for welding the electrode to the terminal. Electrical resistance within the battery is decreased and thermal conductivity of the cell is increased allowing for superior heat removal from the battery and increased efficiency. Increased internal pressure within the battery can be alleviated without damaging or removing the battery from service while keeping the contents of the battery sealed off from the atmosphere by a pressure release system. Nonoperative cells within a battery assembly can also be removed from service by shorting the nonoperative cell thus decreasing battery life.

The invention relates to a temperature-sensitive-type intelligent nano particles used in a drilling fluid and a preparation method thereof. In the invention, a silane coupling agent is used for performing ultrasound surface modification to nano SiO2 and a vinyl functional group is introduced. With the surface-modified nano SiO2, a temperature-sensitive-type monomer and a hydrophilic monomer are subjected to a polymerization reaction in a water medium with a co-solvent with addition of an initiator, wherein granularity distribution of the temperature-sensitive-type intelligent nano particles is D10 <= 100 nm, D 50 <= 165 nm and D90 <= 260 nm. When the temperature is higher than a sensitive value, the nano particles achieve double functions of both physical blocking and chemical inhibition, so that a continuous compact hydrophobic blocking layer is formed inside shale, thereby achieving effects of preventing and delaying pressure transmission and filtration invasion, and further enhancing stability of a shale well wall.
