Abstract: Disclosed is a method for forming a catalyst bed for catalytic decomposition of hydrogen peroxide, which uses 3-D printing techniques to form a porous metal backbone and treating the surface of the metal backbone to activate the surface, wherein the metal backbone is formed of a noble metal or a manganese complex. Also disclosed is a rocket engine having a 3D printed catalyst for catalytic decomposition of hydrogen peroxide, a fuel store, an oxidizer store, and a rocket engine, wherein the oxidizer is a stabilized solution of hydrogen peroxide, and a 3D printed catalyst bed.

Abstract: A hemp biodegradable absorbent according to various aspects of the present technology comprises receiving hemp biomass and processing the biomass into a desired particle range through a separation process. The separation process may comprise an initial filtration to separate out particles having a size of greater than 500 ?m, pulverizing or sifting the remaining particles into a plurality of grades in a range of 0.5 ?m to 50 ?m, and selecting at least one grade of particles to form the absorbent. The selected particles are dried to a moisture content of less than about 10% to create a hemp biodegradable absorbent base that can be used to form various types of absorbent products that may provide an absorbent capacity of between about at least about 300% and up to about 600% by weight. The hemp biodegradable absorbent may also be effective at absorbing both oil-based and water-based liquids.

Abstract: A method for determining an optimum spacing of seismic energy sources based on mutual admittance includes deploying a plurality of seismic energy sources along a source line, separated by a selected spacing. Seismic receivers are deployed along a receiver line orthogonal to the source line. Seismic energy is simultaneously transmitted from each of the plurality of seismic energy sources while recording signals from the seismic receivers. The transmitting and recording of signals is repeated for a plurality of different spacings between the energy sources. Seismic energy in the recorded signals is determined in separate time windows selected to represent reflected body wave signal, and source generated ground roll noise, respectively. A signal-to-noise ratio with respect to the spacing of the seismic energy sources is calculated and the optimum spacing between energy sources is selected based on the signal-to-noise ratio.

Abstract: Provided here is a copy protection method and apparatus to confuse currently available personal computer software (and other content) copying packages by use of unexpected (“illegal”) special characters in the volume (or directory) name for the software or other content or data subject to being copied. This method can be used alone or with a broad range of other known copy protection technologies such as RipGuard (available from Macrovision Corp.). Also provided here is a method and apparatus to defeat the confusion method, thereby allowing copying of such copy protected software.

Abstract: A heat-sensitive composition, for example a coating on a lithographic printing plate, comprises a carboxylic acid derivative of a cellulosic polymer. The composition may contain a radiation absorbing compound and suitable electromagnetic radiation, preferably infra-red radiation, may be used to heat the composition imagewise. The presence of the cellulosic polymer enhances resistance to certain organic liquids.
