  • Patent number: 10435639
    Abstract: A process for making cerium dioxide nanoparticles containing at least one transition metal (M) utilizes a suspension of cerium hydroxide nanoparticles prepared by mechanical shearing of an aqueous mixture containing an oxidant in an amount effective to enable oxidation of cerous ion to ceric ion, thereby forming a product stream that contains transition metal-containing cerium dioxide nanoparticles, Ce1-xMxO2, wherein “x” has a value from about 0.3 to about 0.8. The nanoparticles thus obtained have a cubic fluorite structure, a mean hydrodynamic diameter in the range of about 1 nm to about 10 nm, and a geometric diameter of less than about 4 nm. The transition metal-containing crystalline cerium dioxide nanoparticles can be used to prepare a dispersion of the particles in a nonpolar medium.

  • Publication number: 20190258490
    Abstract: A new layer for runtime detection of vendor hooks, with respect to a program module, includes mapping of branching instructions and their respective targets. When the program module is compiled, branch instructions are mapped and recorded to generate one or more branch maps. A branch map includes target program module addresses (or associated respective placeholders) and respective instruction offsets. At runtime, placeholders are replaced with respective target program module addresses. At runtime, actual branching information is compared to branching information included in the branch map. If a discrepancy is detected between runtime branching information and the corresponding branching information recorded in the branch map, a responsive action is triggered.

  • Patent number: 10382459
    Abstract: Threat detection instrumentation is simplified by providing and updating labels for computing objects in a context-sensitive manner. This may include simple labeling schemes to distinguish between objects, e.g., trusted/untrusted processes or corporate/private data. This may also include more granular labeling schemes such as a three-tiered scheme that identifies a category (e.g., financial, e-mail, game), static threat detection attributes (e.g., signatures, hashes, API calls), and explicit identification (e.g., what a file or process calls itself). By tracking such data for various computing objects and correlating these labels to malware occurrences, rules can be written for distribution to endpoints to facilitate threat detection based on, e.g., interactions of labeled objects, changes to object labels, and so forth.

  • Patent number: 10279393
    Abstract: The present process provides a method for synthesizing oxide-free copper nanometal dispersion in a free and reduced state using a solution phase synthesis process. A solution of an organic reducing agent containing at least two proximal nitrogen atoms is reacted with a separate solution containing a copper salt reformulated into a charge transfer complex. The reaction products are stabilized with Lewis bases and Lewis acids and optionally can be concentrated by removing a portion of the volatile low molecular weight solvent by either the use of a partial vacuum or by chemical extraction into another phase.

  • Patent number: 10279331
    Abstract: The present process provides a method for synthesizing difficult to make oxide-free nanometals and such as Zn, Sn and Ti and alloys of the period 4 and 5 transition metal elements in a free and reduced state using a solution phase synthesis process. Also provided is a method for stabilizing their associated colloidal metal and alloy dispersions under kinetic control at modest temperatures (<90 degrees Celsius). A solution of an organic reducing agent containing at least two proximal nitrogen atoms is reacted with a separate solution containing one or more metal-organic salts dissolved in the same or different low molecular weight solvent as the reducing agent. The reaction products are stabilized with Lewis bases and Lewis acids and optionally can be concentrated by removing a portion of the volatile low molecular weight solvent by either the use of a partial vacuum or by chemical extraction into another phase.
