Compositionally-graded ferroelectric thin films by solution epitaxy produce excellent dielectric stability.

The composition in ferroelectric oxide films is decisive for optimizing properties and device performances. Controlling a composition distribution in these films by a facile approach is thus highly desired. In this work, we report a solution epitaxy of PbZrTiO films with a continuous gradient of Zr concentration, realized by a competitive growth at ~220 °C.

The Complete Genome of Emcibacter congregatus ZYL, a Marine Bacterium Encoding a CRISPR-Cas 9 Immune System.

Emcibacter congregatus ZYL was isolated from a sediment sample cultured in situ in a coast located in the East China Sea. The genome of E. congregatus ZYL was sequenced and assembled into one single circular chromosome with the size of 4,189,011 bp and G+C content of 52.

Immune responses and protection induced by Brucella suis S2 bacterial ghosts in mice.

With the purpose of generating Brucella suis bacterial ghosts and investigating the immunogenicity of bacterial ghosts as a vaccine candidate, the lysis gene E and temperature-sensitive regulator cassette were cloned into a shuttle plasmid, pBBR1MCS-2, for construction of a recombinant temperature-sensitive shuttle lysis plasmid, pBBR1MCS-E. pBBR1MCS-E was then introduced into attenuated B. suis live vaccine S2 bacteria, and the resultant transformants were used for production of B.
