摘要： A method of fracturing a subterranean formation which surrounds a well bore comprises the steps of providing a fracturing fluid, and injecting the fracturing fluid into the well bore at a pressure sufficient to form fractures in the subterranean formation which surrounds the well bore. The pressure is then released from the fracturing fluid, after which the fluid may be removed from the well and the well placed into production. The fracturing fluid comprises an aqueous liquid, a polysaccharide soluble or dispersible in the aqueous liquid in an amount sufficient to increase the viscosity of the aqueous liquid, an enzyme breaker which degrades said polysaccharide at a temperature above 180.degree. F. Fracturing fluid compositions and enzyme breaker systems useful for carrying out the invention are also disclosed.

摘要： A carbon/nanoparticle nanofiber includes a carbon base structure and a plurality of nanoparticles that include a lithium alloy or a lithium alloy precursor. One or more nanofibers may be formed into a nonwoven fabric. The fabric may be utilized as an electrode, such as for example in a battery. The carbon/nanoparticle composite nanofiber may be fabricated by forming a polymer/nanoparticle nanofiber, such as for example by a spinning technique, and carbonizing the polymer/nanoparticle nanofiber.
