Abstract: A knowledge accelerator platform automatically builds and maintains a knowledge index of assets stored across a plurality of sources to allow consolidated searching of assets in the plurality of sources. The platform automatically processes the assets to extract metadata information and record labels for each asset in the index, without storing the content of an asset itself in the index, where a semantic dictionary maps labels to terminology in different domains. The knowledge accelerator platform further provides an internal user interface that allows internal users to evaluate the knowledge contained in the assets at a high level and thus identify knowledge gaps that can be mitigated, and promote quality assets within targeted user communities. The knowledge accelerator platform also provides an external user interface that recommends assets to users based on various factors such as their experience, status, and domain interests.

Abstract: A purification method for detection of a strontium isotope in a silk cultural relic. The method includes: (1) enrichment of the strontium isotope: after cleaning the silk cultural relic, adding the silk cultural relic to a digestion agent for microwave digestion, and conducting evaporation drying; and adding a dried product to a nitric acid solution for centrifugal separation, and extracting a supernatant; and (2) purification of the strontium isotope: first, mixing 4?,4?(5?)-di-tert-butyldicyclohexano-18-crown-6 and a defoamer and adsorbed to a purified resin separation column, and pre-cleaning the purified resin separation column with a nitric acid solution; next, injecting the supernatant in step (1) into the purified resin separation column with a nitric acid solution as a carrier solution; and then, injecting an 84Sr solution and an elution solution into the purified resin separation column in sequence to obtain a separated and purified strontium solution.
