Patent number: 11806444Abstract: Disclosed is a new 3D bioprinting method of soft polymeric material such as a hydrogel or elastomer and/or cells for scaffolds or devices with structures. The method utilizes in one aspect extrusion based printing of polymer solutions, hydrogels and cells referred as direct ink writing (DIW) or BioPlotting that is modified to offer break-through advantages. The method may utilize sequential printing of a photocurable polymer solution or matrix material, and a functional hydrogel and/or cells. Printing within or inside of a viscous non-cured layer is accomplished by printing cells directly into the functional hydrogel. The viscous layer does not need to be shear thinning and thus allows use of a wide variety of bioinks never before allowed because of shear thinning and recovery requirement of commonly utilized extrusion based embedded bioprinting approach. Complex printing patterns never before allowed for bioinks are now possible utilizing this new printing method.Type: GrantFiled: January 31, 2022Date of Patent: November 7, 2023Assignee: New Jersey Institute of TechnologyInventors: Murat Guvendiren, Shen Ji, Alperen Abaci

Patent number: 11773026Abstract: A DC conductive, low RF/microwave loss titanium oxide ceramic provides, at room temperature, a bulk DC resistivity of less than 1×1011 ohm-meters and an RF loss tangent of less than 2×10?4 at 7.5 GHz and less than 2×10?5 at 650 MHz. The resistivity is reduced by oxygen vacancies and associated Ti3+ and/or Ti4+ centers created by sintering in an atmosphere containing only between 0.01% and 0.1% oxygen. The reduced resistivity prevents DC charge buildup, while the low loss tangent provides good RF/microwave transparency and low losses. The ceramic is suitable for forming RF windows, electron gun cathode insulators, dielectrics, and other components. An exemplary Mg2TiO4—MgTiO3 embodiment includes mixing, grinding, pre-sintering in air, and pressing 99.95% pure MgO and TiO2 powders, re-sintering in air at 1400° C.-1500° C. to reduce porosity, and sintering at 1350° C.-1450° C. for 4 hours in an 0.05% oxygen and 99.05% nitrogen atmosphere.Type: GrantFiled: September 14, 2020Date of Patent: October 3, 2023Assignee: Euclid Techlabs, LLCInventors: Alexei Kanareykin, Elizaveta Arkadievna Nenasheva
