Policy enforcement in a secure data file delivery system
A server interacts with a sender to form a package which can include one or more attached data files to be sent to one or more recipients, and the server applies a policy established by a policy authority of the sender to the package. Since the server both forms the package through interaction with the sender and applies the policy, violations of the policy by the package can be brought to the sender's attention during an interactive session with the sender and before encryption of all or part of the package. As a result, the sender is educated regarding the policy of the sender's policy authority, and the sender can modify the package immediately to comport with the policy. The server delivers the package to intended recipients by sending notification to each recipient and including package identification data, e.g., a URL by which the package can be retrieved. |

Electrode structure and method for making same
Electrode structures and methods for making the same are generally described. In certain embodiments, the electrode structures can include a plurality of particles, wherein the particles comprise indentations relative to their convex hulls.

Active electrode materials and methods for making the same
In an example of a method for making a silicon-based active electrode material, a silicon active material precursor is introduced into a carrier gas. Another active material precursor is introduced into the carrier gas prior to, simultaneously with or subsequent to the silicon active material precursor. The other active material precursor is selected from a tin active material precursor, an aluminum active material precursor, a graphene active material precursor, and combinations thereof. The carrier gas containing the precursors is exposed to plasma vaporization, and a material is formed. The material includes i) an alloy of phase separated silicon and tin and/or aluminum, or ii) a graphene layer having silicon nanoparticles and tin nanoparticles, aluminum nanoparticles, or combinations of tin and aluminum nanoparticles deposited on a surface thereof, or iii) a graphene layer having an alloy of phase separated silicon and tin, aluminum, or tin and aluminum deposited on a surface thereof. |
