Abstract: The present disclosure provides a method for synthesizing spherical copper powder and the copper powder obtained therefrom. The method includes mixing a copper oxide powder with a carbon source to obtain a mixture; heating the mixture at a temperature of 600-1070° C. for a period of more than 20 minutes in an inert atmosphere to obtain spherical copper powder; and separating the spherical copper powder from carbon to obtain pure spherical copper powder. The present method is a single step process where a precursor copper oxide powder is reduced and spherodized simultaneously to provide spherical copper powder. Spherical copper powders provided by the present methods are dense and spherical and have a mean particle size of less than 250 microns, purity of at least 98.5% by weight of copper, and an oxygen content of less than 0.25% by weight.

Abstract: Generally discussed herein are devices, systems, and methods for adaptive authorization using a local route as a named location. A method can include defining a local route and a corresponding local route endpoint, associating a compute resource as a destination of the local route endpoint, defining an adaptive authorization policy that limits access to the compute resource to be through the local route endpoint, and enforcing access to the compute resource based on the defined adaptive authorization policy.
