    Abstract: A hierarchical heat exchanger manifold includes: first and second fluid passages respectively open to an inlet and an outlet in a first level of the heat exchanger manifold; a plurality of first and second fluid passages in a second level of the heat exchanger manifold; and a plurality of first and second fluid passages in a third level of the heat exchanger manifold. A number of the first fluid passages in the third level is greater than a number of the first fluid passages in the second level. Each of the first fluid passages in the second level is in fluid communication with the inlet and at least one of the first fluid passages in the third level, and each of the second fluid passages in the second level is in fluid communication with the outlet and at least one of the second fluid passages in the third level.

    Abstract: Some variations provide an aluminum (Al) alloy containing at least 0.1 at % zirconium (Zr) and/or at least 0.1 at % chromium (Cr), wherein the aluminum alloy is in the form of an additively manufactured object. Other variations provide an aluminum-containing powder comprising Al particles, Cr particles, and Zr particles, wherein at least some of the Cr particles as well as at least some of the Zr particles are physically and/or chemically assembled on surfaces of the Al particles, and wherein the aluminum-containing powder contains at least 0.1 at % Zr and at least 0.1 at % Cr. In this invention, the combination of surface functionalization and additive manufacturing has fundamentally created a new composition space of valuable aluminum alloys. The disclosed Al alloys are strong, thermally stable, and corrosion-resistant.

    Abstract: Some variations provide a preceramic resin precursor formulation comprising: first molecules comprising at least one Si—C bond and/or at least one Si—N bond, wherein the first molecules include at least one silyl hydride group (Si—H) available for hydrosilylation; and second molecules with at least one unsaturated carbon-carbon bond attached to a UV-active functional group. The first molecules and second molecules may be reacted, via hydrosilylation with a homogeneous or heterogeneous metal-containing catalyst, to produce third molecules comprising a hydrosilylation-modified polysilazane that contains the UV-active functional group. Many possible starting formulations are described, and methods are disclosed for carrying out the chemical reactions to generate the hydrosilylation-modified polysilazanes. The hydrosilylation-modified polysilazanes may then be 3D-printed and thermally treating to fabricate a ceramic material.

    Abstract: A method and apparatus for enhancing the stability of an oscillator circuit by generating a comb of frequencies in a non-linear resonator member in response to a drive frequency, the oscillator circuit including a voltage controlled oscillator which is locked to a particular tooth of the comb of frequencies produced by the non-linear resonator member at a drive frequency for which the absolute value of the first derivative of the drive frequency versus said comb frequency is greater than 1, and wherein the second voltage controlled oscillator is coupled with a phase locked loop circuit which controls the locking of the second voltage controlled oscillator to said particular tooth of the comb of frequencies.

    Abstract: A method of forming concurrently openings in a substrate or wafer or a portion of substrate or wafer openings therein at least one of the openings has a relatively high aspect ratio and another one of the openings has a relatively low aspect ratio, the method comprising: bonding the substrate or wafer or a portion of substrate or wafer to a carrier substrate; forming a ring trench in the substrate or wafer or in a portion of the substrate or wafer, the ring trench having an outer perimeter that corresponds an outer perimeter of the another one of the openings having said relatively low aspect ratio and having an inner perimeter spaced from the outer perimeter by a predetermined distance; forming an opening in said substrate or wafer or in a portion of substrate or wafer having said high aspect ratio concurrently with the forming of the ring trench; and separating the substrate or wafer or in a portion of the substrate or wafer from the carrier substrate.

    Abstract: Some variations provide a metal matrix nanocomposite composition comprising metal-containing microparticles and nanoparticles, wherein the nanoparticles are chemically and/or physically disposed on surfaces of the microparticles, and wherein the nanoparticles are consolidated in a three-dimensional architecture throughout the composition. The composition may serve as an ingot for producing a metal matrix nanocomposite. Other variations provide a functionally graded metal matrix nanocomposite comprising a metal-matrix phase and a reinforcement phase containing nanoparticles, wherein the nanocomposite contains a gradient in concentration of the nanoparticles. This nanocomposite may be or be converted into a master alloy. Other variations provide methods of making a metal matrix nanocomposite, methods of making a functionally graded metal matrix nanocomposite, and methods of making a master alloy metal matrix nanocomposite. The metal matrix nanocomposite may have a cast microstructure. The methods disclosed enable various loadings of nanoparticles in metal matrix nanocomposites with a wide variety of compositions.
