Abstract: The present disclosure provides methods of activating an enzyme, such as error prone or template independent polymerase, using electricity to alter pH of a reaction zone and reaction site from an inactivating pH at which the enzyme is inactive to an activating pH at which the enzyme is active to add a nucleotide to an initiator or growing polymer chain. The activating pH can then be changed back to an inactivating pH and the process repeated as many times as desired to produce a target nucleic acid sequence.

Abstract: The disclosure provides methods for making a polynucleotide wherein the addition of nucleotides can be physically, chemically and/or enzymatically controlled. The methods include combining a selected nucleotide, cations, an error prone or template independent DNA polymerase at a reaction site including an initiator sequence attached thereto and having a 3? terminal nucleotide, wherein the reaction reagents can be modulated and under conditions that allow covalent addition of one or more of a selected nucleotide to the 3? terminal nucleotide such that the selected nucleotide becomes a 3? terminal nucleotide, and repeating the addition step until the polynucleotide is formed.

Abstract: A disaster-proof data safe with multiple, insulated, surrounding solid structural metal walls for housing functioning digital electronic computing, data processing, data storage, communications and high power density blade server systems has one or more coaxial helical coil coolant tubes circulating a coolant liquid encircled around an interior hexahedral, housing space for removing heat generated in the housing space and insulating the housing space from sources of heat external to the safe. Features of the safe include a plurality of longitudinal heat sink bars thermally coupled to the encircling helical coil coolant tubes supported either by the helical coil coolant tubes or the interior structural metal sidewalls of the housing space. The helical coil coolant tubes and the heat sink bars are preferably composed from metals such as copper, aluminum and their alloys that have a high thermal conductivity and that retain structural integrity at temperature ranging up to 500° C.

Abstract: A method is provided for forming a plurality of regions of magnetic material in a substrate having a first approximately planar surface. The method comprises the steps of fabricating projections in the first surface of the substrate, depositing onto the first surface a magnetic material in such a way that the tops of the projections are covered with magnetic material, and depositing filler material atop the substrate so produced. The filler material may then be planarized, for example by chemical-mechanical polishing. In an alternative embodiment magnetic material is deposited on a substrate and portions of it are removed, leaving islands of material. Filler material is then deposited, which may be planarized.

Abstract: Methods of defining servo patterns and data patterns for forming patterned magnetic media are described. For one method, a lithographic process is performed to define a servo pattern in servo regions on a substrate. The lithographic process also defines a first data pattern in data regions of the substrate. The first data pattern is then transferred to (i.e., etched into) the data regions. Self-assembly structures are then formed on the data pattern in the data regions to define a second data pattern. The servo pattern is then transferred to the servo regions and the second data pattern is transferred to the data regions. Thus, the servo pattern is defined through lithographic processes while the data pattern is defined by a combination of lithographic processes and self-assembly.

Abstract: A method for making a master mold to be used for nanoimprinting patterned-media magnetic recording disks results in a master mold having topographic pillars arranged in a pattern of annular bands of concentric rings. The ratio of circumferential density of the pillars to the radial density of the concentric rings in a band is greater than 1. The method uses sidewall lithography to first form a pattern of generally radially-directed pairs of parallel lines on the master mold substrate, with the lines being grouped into annular zones or bands. The sidewall lithography process can be repeated, resulting in a doubling of the number of lines each time the process is repeated. Conventional lithography is used to form concentric rings over the radially-directed pairs of parallel lines. After etching and resist removal, the master mold has pillars arranged in circular rings, with the rings grouped into annular bands.
