Abstract: Compositions and methods are provided for the enhanced in vitro synthesis of polypeptides. In order to improve the performance of in vitro protein synthesis reactions, metabolic inhibitors, or manipulation of a source organism, is used to diminish or avoid the action of enzymes responsible for undesirable amino acids production or depletion. A homeostatic system may be used for production of ATP, where the required high energy phosphate bonds are generated in situ, e.g. through coupling with an oxidation reaction. The homeostatic energy source will typically lack high energy phosphate bonds itself, and will therefore utilize free phosphate in the reaction mix during generation of ATP. The homeostatic energy source is provided in combination with an enzyme that catalyzes the creation of high energy phosphate bonds and with an enzyme that can use that high energy phosphate bond to regenerate ATP.

Abstract: Disclosed is a method for preparing a high performance, negative electrode for Ni/metal hydride cells. A Zr-based hydrogen storage alloy, a binder comprising a mixture of polytetrafluoroethylene and 50th and a thickening agent (hydroxypropylmethyl cellulose), and a current collector comprising carbon black and copper are slurried and molded into a paste-type electrode. In a closed type cell, the copper repetitively undergoes melting and deposition on the electrode during charging and discharging cycles, allowing the electrode to show a similar change in surface morphology and electrochemical properties to that of a conventionally electroless plated electrode.

Of particular interest is the synthesis of polymers, e.g. nucleic acids, polypeptides, and complex carbohydrates. A homeostatic system is used for production of ATP, where the required high energy phosphate bonds are generated in situ, e.g. through coupling with an oxidation reaction. The homeostatic energy source will typically lack high energy phosphate bonds itself, and will therefore utilize free phosphate in the reaction mix during generation of ATP. Since inorganic phosphate can be an inhibitory by-product of synthesis, the period of time when synthesis is maintained in vitro can be extended. The homeostatic energy source is provided in combination with an enzyme that catalyzes the creation of high energy phosphate bonds and with an enzyme that can use that high energy phosphate bond to regenerate ATP.

Abstract: There are disclosed Mm/Ni type hydrogen storage alloys for Ni/MH secondary cells. The alloys which allow the cells to be of high performance and high capacity can be prepared at lower costs than the production costs of conventional Co-rich hydrogen storage alloys, by reducing the amount of the Co element. The Co element is partially or wholly replaced by by Cr, Cu, Fe, Zn and/or Zi, which are each known to be of stronger affinity for hydrogen than is Co and to have such a strong oxidation tendency in electrolytes as to form a highly dense oxide. The novel alloys have discharge capacities and electrode life span as good as those of the conventional Co-rich hydrogen storage alloys but have advantages over the Co-rich alloys, including performance-to-cost.

Abstract: A method for producing an electrode of Ni/metal hydride alloy secondary cells. The electrode may be produced by mixing an active material with approximately 10-50 wt % of Cu powders, which can serve as a binder as well as a current collector, and cold-pressing the mixture at a pressure of 10 ton/cm. As the Cu-compacted electrode continues to experience the cycle of charge and discharge, the desolution-deposition of Cu is gradually produced. This desolution-deposition of Cu allows Cu to be deposited on the surface of the electrode comprising the hydrogen storage alloy, so that the electrode can be similar to a conventional Cu-electroless plated electrode in surface morphology. Consequently, the method of the invention can be an alternative for conventional electroless plating, which significantly improves the general functions of hydrogen storage alloy electrode, including low temperature dischargeability and high rate capability, without producing pollution of the environment.
