    Abstract: A method and system for controlled rate freezing and nucleation of materials is provided. The presently disclosed system and method provides the ability to rapidly cool the materials contained in vials or other containers within a cooling unit via forced convective cooling using a laminar and uniform flow of cryogen in proximity to the plurality of vials disposed within the cooling unit. The rapid cooling of the biological materials is achieved by precisely controlling and adjusting the temperature of the cryogen being introduced to the system as a function of time. The presently disclosed methods to systems also provide nucleation control via temperature quench and depressurized nucleation control.

    Abstract: A method and electrode assembly for treating a substrate with a non-equilibrium plasma in which the electrode assembly has two or more spaced barrier electrodes and a ground electrode spaced apart from the two spaced barrier electrodes for passage of a substrate to be treated. Plasma fluid medium is introduced between the barrier electrodes and is biased to provide a greater flow to an inlet region of the electrode assembly to help inhibit the ingress of air. Each of the barrier electrodes can be provided with central and leg sections having passages for introducing a cooling fluid into one of the leg sections and discharging said cooling fluid from the other of the leg sections. The central section can be provided with a transverse cross-sectional area less than that of the leg sections to increase velocity in the central section.

    Abstract: A method of oxygen-free heat treatment of a steel part in an atmospheric pressure furnace is disclosed. The present method employs an oxygen-free controlled gas atmosphere including hydrogen gas in concentrations between about 1.0 percent to 10.0 percent, a hydrocarbon gas, such as propylene, in concentrations of between about 0.1 percent and 10.0 percent that varies as a function of time, with the balance of the gas atmosphere being nitrogen. The presently disclosed oxygen-free heat treatment process, preferably a carburization process, uses a precisely controlled atmosphere to minimize inter-granular oxidation, eliminate the formation of soot and cementite or other metallic carbides, and avoid hydrogen embrittlement.

    Abstract: A method of oxygen-free heat treatment of a steel part in an atmospheric pressure furnace is disclosed. The present batch treatment process employs an oxygen-free controlled gas atmosphere including hydrogen gas in concentrations between about 1.0 percent to 10.0 percent, a hydrocarbon gas, such as propylene, in concentrations of between about 0.1 percent and 10.0 percent that varies as a function of time, with the balance of the gas atmosphere being nitrogen. The present continuous furnace treatment process employs a plurality of zones with each zone including an oxygen-free controlled gas atmosphere including hydrogen gas in concentrations between about 1.0 percent to 10.0 percent that varies across the different zones, a hydrocarbon gas, such as propylene, in concentrations of between about 0.1 percent and 10.0 percent that varies across the different zones, with the balance of the gas atmosphere within each zone being nitrogen. The presently disclosed oxygen-free heat treatment processes, preferably carburization processes, use a precisely controlled atmosphere to minimize inter-granular oxidation, eliminate the formation of soot and cementite or other metallic carbides, and avoid hydrogen embrittlement.
