Abstract: A group of tertiary amine azides are useful as hypergolic fuels for hypergolic bipropellant mixtures. The fuels provide higher density impulses than monomethyl hydrazine (MMH) but are less toxic and have lower vapor pressures that MMH. In addition, the fuels have shorter ignition delay times than dimethylaminoethylazide (DMAZ) and other potential reduced toxicity replacements for MMH.
Abstract: An apparatus for assaying a tumor drug delivery vehicle and or drug can include an idealized microvascular network (IMN) of one or more interconnected idealized flow channels in fluid communication through a porous wall with a tissue space (e.g., idealized tissue space) containing animal cells and means for quantifying drug delivery through the IMN to the animal cells.
Abstract: Methods of assaying the leukocyte adhesion cascade (LAC) and monitoring leukocyte rolling, adhesion, and/or migration can be implemented with an apparatus that includes an idealized microvascular network (IMN) of one or more interconnected idealized flow channels in fluid communication through a porous wall with a tissue space (e.g., idealized tissue space). The methods of assaying the LAC can be implemented with means for quantifying modulation of the leukocyte adhesion cascade. Methods of assaying the LAC can be implemented with the device and one or more active agents to monitor leukocyte rolling, adhesion, and/or migration in the presence of absence of the active agent. Migration can be through the idealized flow channels, through the porous wall, and/or into the tissue space.

Abstract: The present invention is a method comprising a direct chirality-selective nucleation and synthesis of single-walled carbon nanotubes from carbon-containing gases using catalytic nanoparticles of uniform size heated by ultra-short laser pulses of selected frequency to temperatures sufficient for carbon nanotube nucleation and synthesis.
Abstract: A catalytic chemical vapor deposition method and apparatus for synthesizing carbon nanotubes and/or carbon nanofibers (CNTs) on a substrate involves selectively heating a catalyst for CNT synthesis on or near the surface of the substrate. Selective heating of the catalyst is achieved using inductive heating from a radio frequency source. Selective heating of the catalyst prevents heating of the substrate and enables the synthesis of CNTs on temperature sensitive substrates.

Abstract: A method for characterizing particle adhesion in microfluidic bifurcations and junctions comprises at least one idealized bifurcation or junction. Multiple bifurcations and/or junctions can be combined on a single microfluidic chip to create microfluidic networks configured for assays specifically to characterize particle interactions at junctions or to screen particles for desired interactions with microfluidic bifurcations and/or junctions.
Abstract: A synthetic microfluidic microvasculature network and associated methods mimic the structure, fluid flow characteristics, and physiological behavior of physiological microvasculature networks. Computational methods for simulating flow and particle adherence in synthetic and physiological microvascular systems and methods for determining parameters influencing particle adhesion and drug delivery are described with applications in the optimization of drug delivery and microvascular treatments and in describing disease mechanisms that affect the microvasculature.

Abstract: The present invention is a catalytic chemical vapor deposition method and apparatus for synthesizing carbon nanotubes and/or carbon nanofibers (CNTs) on a substrate by selectively heating a catalyst for CNT synthesis on or near the surface of the substrate. Selective heating of the catalyst is achieved using an exothermic oxidation reaction on the surface of the catalyst, inductive heating from a radio frequency source, or both. Selective heating of the catalyst prevents heating of the substrate and enables the synthesis of CNTs on temperature sensitive substrates.
