Abstract: A showerhead includes a plurality of plenums and a plurality of through holes positioned in the plurality of plenums. The plenums are stacked in a sequential order in an axial direction perpendicular to a semiconductor substrate. The plenums extend radially fully across the semiconductor substrate. The plenums are disjoint from each other and are configured to respectively supply a first metal precursor, a second metal precursor, and a reactant via the respective plenums without intermixing the first metal precursor, the second metal precursor, and the reactant in the plenums. The through holes of the respective plenums are arranged in a radial direction, which is perpendicular to the axial direction, in the same sequential order as the sequential order of the plenums. The through holes of the plenums open along a flat surface at a bottom of the showerhead. The flat surface extends radially fully across the bottom of the showerhead.

Abstract: A system and method for tissue fabrication involves the use of charge manipulation between two biomaterials to generate a shrinking response, which effectively enhances the resolution of bioprinted hydrogels. The charge manipulation can be utilized to generate tissue engineered thin, membranous tissues, such as the periosteum, which is approximately one hundred microns in thickness. Thin membranous tissues in the body also have relatively complex anatomies containing multiple cell populations, and no prior strategies allow for the effective and biomimetic generation of these tissues, which can have significant impact on tissue regeneration.

Abstract: Current approaches in small diameter vascular grafts for coronary artery bypass surgeries fail to address physiological variations along the graft that contribute to thrombus formation and ultimately graft failure. An interlayer drug delivery system can sustain delivery of heparin through the graft with a high degree of temporal and spatial control. A heparin-loaded gelatin methacrylate interlayer sits between a biohybrid composed of decellularized bovine pericardium and poly(propylene fumarate) and UV crosslinking is controlled via 3D printed shadow masks. The masks enable control of the resultant gelMA crosslinking and properties by modulating the incident light intensity on the graft. High doses of heparin have detrimental effects on endothelial cell function. When exposed to heparin in a slower, more sustained manner consistent with the masks, endothelial cells behave similarly to untreated cells.

Abstract: A solid fuel burning device has at least one burn chamber wall, a burn chamber base, and an interior burn chamber. The burn chamber base is capable of supporting a combustible solid fuel thereon. At least one of the burn chamber walls is radially offset with respect to another of the burn chamber walls. At least two longitudinally extending air inlets are formed in the space between a first longitudinal edge of at least one of the burn chamber walls and a second longitudinal edge of another burn chamber wall. Each of the longitudinally extending air inlets tangentially directs an entry of air into the interior burn chamber to induce an interior swirl of air in the interior burn chamber. The interior swirl of air in the interior burn chamber causes a flame of a combusting solid fuel to swirl in the interior burn chamber.
