      This paper provided insights into mechanisms of the elementary step of monomeric water motions, and enriched our knowledge of one-molecule science. The findings, of the orientational preferences and correlation for the atop-to-atop motions of an H2O on Al{100}, have widespread interests in research communities. The authors also provided theoretical evidence that the favored mechanisms can be classical hopping coupled with either the molecular flipping or in-plane reorientations, in contrast to the simple translational motions; while quantum tunneling assisted motion is not favored for an H2O via the nearest neighbor diffusion. The paper showed that the symmetry match between an H2O and the surface square lattice controlled molecular mechanisms of the surface motions.

      The binary-phase structure of the grating polarizers is easy to mass produce. The theoretical efficiency is high (>85%) and devices have high polarization isolation (>1000:1). The deep-etched fused silica grating should functions as a good device for polarization separation in a variety of practical application. The significant scientific meaning is that an isotropic material, such as fused silica, can be transformed into a polarization-separation device by introducing an artificial subwavelength structure.

      Nowadays to prepare pure metal nanoparticles and pure nanocrystalline metal bulk materials is still very hard. Especially, to prepare pure rare-earth nanoparticles and nanocrystalline bulks is a big challenge in the field of nanoscience and nanotechnology. This paper proposed a novel technique to prepare ultra-fine nanocrystalline RE bulks with advanced properties. The essential importance is that the proposed route and techniques can be extended to prepare any nano-metallic materials that are active in the open air, thus it makes possible to study structures and properties of many metallic nanomaterials that could be hardly prepared before.

  • A novel redox-potential-based screening strategy for rapid isolation of Klebsiella pneumoniae mutants with enhanced 1,3-propanediol producing capability

      In many years the Chinese Industrial Biotechnologists spent a lot of energy on increasing the production level of useful metabolites. However, they rarely develop new methodology which would result in a revolutionary development of a certain biotechnological process. Du et al. describes a novel redox-potential-based screening strategy for rapid isolation of Klebsiella pneumoniae mutants with enhanced 1,3-propanediol (a bulk chemical) production capability. The result provides a novel screening strategy which could be helpful to screen/develop strains involved in the oxidoreduction biosynthesis, which is of great potential for industrial biotechnology. The other significance of this study is that it is a typical hypothesis-driven research, which is rarely found in the industrial biotechnology research field in China. The acceptance of this nice article by Applied & Environmental Microbiology symbolizes that the industrial biotechnologists are more focusing on the fundamental research area, e. g. development of novel methodologies. This is important for achieving a bright future for China’s bioeconomy.

      In this study, a transgenic mouse model with 13bp deletion in Col10a1 (13del) was made and characterized. The same mutation has been found in human patients with Schmid metaphyseal chondrodysplasia (SMCD). This work has substantially advanced our understanding of 13del as well as its pathological roles in SMCD. It also creates a valuable mouse model for studying cartilage and bone development. The observations made on expansion of hypertrophic zone and its correlation with activation of ER stress significantly open up the field and provide new avenues for future studies.
