Patent number: 10766832Abstract: The present invention generally concerns a nano-enhanced explosive that is integrated at many points across an explosive train. More specifically, a nano-enhanced explosive is formed when a nanocomposite we call nMx is combined with a secondary high explosive. nMx is made of Li3AlH6 nanoparticles, elemental Al nanoparticles, an amount of Ti metal, and a nanoscale organic layer having unique burning profiles that lend energy to the explosive process including increased shockwave propagation through a chemical explosive and increased temperatures and gaseous pressure build up and release in and about the same. Our nano-enhanced explosive can be integrated at various points across an explosive train, e.g. use within a detonation cord (fuse), or as a detonation charge (initiator), or as the main charge, where the use of the nano-enhanced explosive can be characterized by the energy lent to projectiles from munitions, bubbles formed by underwater explosive trains, or blast profiles.Type: GrantFiled: June 8, 2018Date of Patent: September 8, 2020Assignee: Saint Louis UniversityInventors: Jacob M Laktas, Ian D Stochl, Gregory J Place, Paul Jelliss, Stephen Chung, Steven W Buckner

Patent number: 10519076Abstract: The present invention generally concerns isolated nanoparticles via the decomposition of a ternary metal hydride. More specifically, the present invention harnesses increased energy densities from two distinct nanoparticles isolated by a precise decomposition of LiAlH4. The singular material is air stable and is a nanocomposite of Li3AlH6 nanoparticles, elemental Al nanoparticles, an amount of Ti metal, and a nanoscale organic layer, which we call nMx. The nanocomposite protects and preserves the high energy densities of the core metals isolated from the controlled reaction and makes the nanoparticles safe to handle in air. The final composite is devoid of byproducts or phase transitions that will decrease the energy output of the nanocomposite. The method of the present invention creates a narrow distribution of nanoparticles that have unique burning characteristics useful for many applications.Type: GrantFiled: December 27, 2017Date of Patent: December 31, 2019Assignee: Saint Louis UniversityInventors: Steven Wayne Buckner, Paul Jelliss, Stephen Chung, Jacob M.

Patent number: 10501385Abstract: The present invention generally concerns decomposing a ternary metal hydride to isolate nanoparticles to use in a fuel grain. More specifically, the present invention harnesses increased energy densities from two distinct nanoparticles isolated by a precise decomposition of LiAlH4. The singular material is air stable and is a nanocomposite of Li3AlH6 nanoparticles, elemental Al nanoparticles, an amount of Ti metal, and a nanoscale organic layer. We call this nanocomposite nMx, which protects and preserves the high energy densities of the core metals isolated from the controlled reaction, making the nanoparticles safe to handle in air. The narrow distribution of nanoparticles has no byproducts or phase transitions that decrease energy output. The unique burning characteristics of nMx enhance the combustion of solid propellant formulations compatible with solid or hybrid rocket motors, where fuel grains are cast, pressed, or 3D printed with nMx powder, a polymeric binder, or optional additives.Type: GrantFiled: August 19, 2017Date of Patent: December 10, 2019Assignee: Saint Louis UniversityInventors: Steven Wayne Buckner, Paul Jelliss, Stephen Chung, Jacob M Laktas, Gregory J Place, Albert Michael Becksted, Jr.

Publication number: 20140122036Abstract: Methods and systems for analyzing the effects of Fluid Solid Interactions (FSI) and pulsation on the transport of Low-Density Lipoprotein (LDL) through an elastic wall (e.g., an arterial wall). A comprehensive multi-layer model for both LDL transport as well as FSI can be analyzed and compared with existing results in limiting cases. The model takes into account the complete multi-layered LDL transport while incorporating FSI aspects to enable a comprehensive study of the deformation effect on the pertinent parameters of the transport processes within an artery. Since the flow inside an artery is time-dependent, the impact of pulsatile flow is also analyzed with and without FSI. The consequence of different factors on LDL transport in an artery is also analyzed.Type: ApplicationFiled: October 8, 2013Publication date: May 1, 2014Applicant: Kambix Innovations, LLCInventors: Kambiz Vafai, Stephen Chung

Publication number: 20140120568Abstract: Low-density lipoprotein (LDL) transport while incorporating the thickening of the arterial wall and cholesterol lipid accumulation can be analyzed. A multi-layered model can be adopted to represent the heterogeneity using the Darcy-Brinkman and Staverman filtration equations to describe transport within the porous layers of the wall. The fiber matrix model can be utilized to represent the cholesterol lipid accumulation and the resulting variable properties. The impact of atherosclerotic wall thickening is shown to be negligible in the axial direction, but is found to be considerable in the radial direction within intima. The reference values of intima's porosity and effective fiber radius are obtained through the fiber matrix model, which characterizes the micro-structure within the intima.Type: ApplicationFiled: October 22, 2013Publication date: May 1, 2014Applicant: Kambix Innovations, LLCInventors: Kambiz Vafai, Stephen Chung
