    摘要： The membrane bioreactor for simultaneous enzymatic cellulose hydrolysis and product separation is a vessel having a lower hydrolysis reaction chamber and an upper distilled water chamber separated by a semipermeable membrane attached to the top of the lower reaction chamber. The membrane is supported on a stainless steel mesh and sealed to the mesh by epoxy glue to prevent leakage. A peristaltic pump is connected to the reaction chamber and maintains a flow of distilled water through the membrane and the upper chamber, the effluent being collected in a beaker or other product collection vessel. The reaction chamber is agitated at a moderate rate by a magnetic stirrer, and the upper chamber is agitated more rigorously by a mechanical stirrer. A thermocouple and temperature controller and a buffer solution, respectively, maintain temperature and pH in the reaction chamber optimal for enzymatic hydrolysis of cellulose.

    摘要： The heat sinks with vibration enhanced heat transfer are heat sinks formed from a first body of high thermal conductivity material. The first body of high thermal conductivity material is received within a thermally conductive housing such that at least one contact face of the first body of high thermal conductivity material is exposed, forming a direct contact interface with a heat source requiring cooling. The heat source requiring cooling may be a liquid heat source, including but not limited to water. The thermally conductive housing is disposed such that at least one contact face of the thermally conductive housing is in direct contact with the vibrating base. The vibrating base applies oscillating waves to the heat sink, thereby increasing heat transfer between the heat source and the heat sink.
