摘要： An ultra-high strength steel (UHSS) includes a composition designed and processed such that the UHSS has properties comprising a tensile strength of about 2020 MPa, a yield strength of about 1781 MPa and a fracture toughness of about 105 MPa·m1/2. The composition incudes Co no more than 8 wt % of the UHSS. The excellent mechanical performance of the UHSS is achieved by nanoscale β-NiAl and M2C precipitates. The strength and toughness of the UHSS are comparable to those of the commercially used Aermet100 and M54 steels, while the cost of the UHSS is extremely low because of low Ni—Co concentration. This notable cost advantage makes the novel UHSS very competitive for potentially broad applications as structural components in the field of aerospace.

摘要： Provided is a Li+ battery comprising an anode comprising an anode active material comprising a plurality of transition metal (TM1)-substituted binary transition metal (TM2) oxide nanocrystals, a cathode in electrical communication with the anode, a separator between the anode and the cathode, and an electrolyte in contact with the anode and the cathode. The anode active material, in a lithiated state, is characterized by a three-dimensional network of the TM1 and nanoparticles of Li2O nanoparticles of the TM2, both types of nanoparticles distributed throughout the network. In a delithiated state, the anode active material is characterized by the network of the TM1 and nanoparticles of an oxide of the TM1 and nanoparticles of an oxide of the TM2, both types of nanoparticles distributed throughout the network. The TM1-substituted binary TM2 oxide may be characterized by a ratio of TM2/TM1 of at least about 5.

摘要： Methods for making nanocomposites are provided. In an embodiment, such a method comprises combining a first type of nanostructure with a bulk material in water or an aqueous solution, the first type of nanostructure functionalized with a functional group capable of undergoing van der Waals interactions with the bulk material, whereby the first type of nanostructure induces exfoliation of the bulk material to provide a second, different type of nanostructure while inducing association between the first and second types of nanostructures to form the nanocomposite.

摘要： A system to generate orientation maps includes a measurement system configured to capture a plurality images of a sample and a computing device in operable communication with the measurement system. The computing device is configured to align the plurality of images of the sample and process the aligned plurality of images to detect one or more regions of interest. The computing device is also configured to generate one or more electron channeling patterns (ECPs) corresponding to the sample based on the one or more regions of interest. The computing device is further configured to generate an orientation map of the sample based on the one or more ECPs.
