Enhanced Photocatalysis from Truncated Octahedral Bipyramids of Anatase TiO with Exposed {001}/{101} Facets.

In this study, we develop a new synthetic method to grow anatase TiO crystals composed of truncated octahedral bipyramids (TOBs) with exposed {001} and {101} facets by a vapor-solid reaction growth (VSRG) method. The VSRG method employs TiCl to react with CaO/Ca(OH) at 823-1043 K under atmospheric pressure. The O-deficient pale-blue TOB TiO crystals display high amount of both {001} and {101} facets.

Towards High Performance Data Analytic on Heterogeneous Many-core Systems: A Study on Bayesian Sequential Partitioning.

Bayesian Sequential Partitioning (BSP) is a statistically effective density estimation method to comprehend the characteristics of a high dimensional data space. The intensive computation of the statistical model and the counting of enormous data have caused serious design challenges for BSP to handle the growing volume of the data. This paper proposes a high performance design of BSP by leveraging a heterogeneous CPU/GPGPU system that consists of a host CPU and a K80 GPGPU.
