Interpenetrated and Polythreaded Co-Organic Frameworks as a Supercapacitor Electrode Material with Ultrahigh Capacity and Excellent Energy Delivery Efficiency.

Synthesizing kinetically stable coordination polymers (CPs) through ligand functionalization can effectively improve their supercapacitive performances. Herein, we have successfully synthesized three novel and topological Co-CPs by varying the flexible N-donor ligand and inorganic anions, namely, interpenetrated [Co(HTATB)( o-bib)]·HO, extended two-dimensional (2D) layered Co(HTATB)( m-bib)·2HO, and three-dimensional (3D) Co(HTATB)( m-bib), where bib is the flexible N-donor bis((1 H-imidazol-1-yl)methyl)benzene linker (where o- and m- refer to ortho and meta positions, respectively) ligand and HTATB is the partial deprotonation mode from 4,4',4″- s-triazine-2,4,6-triyl-tribenzoic acid. Various Co-CPs have been directly applied in the field of supercapacitors.

Short distance intra coding scheme for high efficiency video coding.

This paper proposes a new intra coding scheme, known as short distance intra prediction (SDIP), for high efficiency video coding (HEVC) standardization work. The proposed method is based on the quadtree unit structure of HEVC. By splitting a coding unit into nonsquare units for coding and reconstruction, and therefore shortening the distances between the predicted and the reference samples, the accuracy of intra prediction can be improved when applying the directional prediction method.
