Publication number: 20210253440Abstract: A method of preparing a lithium-ion conducting garnet via low-temperature solid-state synthesis is disclosed. The lithium-ion conducting garnet comprises a substantially phase pure aluminum-doped cubic lithium lanthanum zirconate (Li7La3Zr2O14). The method includes preparing nanoparticles comprising lanthanum zirconate (La2Zr2O7-np) via pyrolysis-mediated reaction of lanthanum nitrate (La(NO3)3) and zirconium nitrate (Zr(NO3)4). The method also includes pyrolyzing a solid-state mixture comprising the La2Zr2O7-np, lithium nitrate (LiNO3), and aluminum nitrate (Al(NO3)3) to give the Li7La3Zr2O14 and thereby prepare the lithium-ion conducting garnet.

Patent number: 10794251Abstract: An engine has an injector communicating with a combustion chamber to introduce a plurality of dosing shots to mix with exhaust gases and regenerate an aftertreatment device downstream of the combustion chamber. An apportionment strategy can apportion a per cylinder quantity, representing the quantity of dosing fuel to introduce per cylinder per combustion cycle, among a predefined number of dosing shots each having a first per shot quantity. The strategy compares the predefined number of dosing shots with a temporal dosing window to determine if predefined number of dosing shots can be conducted within the temporal dosing window. If so, the strategy proceeds to introduce the predefined number of dosing shots and if not, the strategy may recalculate a reduced number of dosing shots and reapportions a second per shot quantity.Type: GrantFiled: September 22, 2016Date of Patent: October 6, 2020Assignee: Caterpillar Inc.Inventors: James S.
