One-dimensional(1D) layered materials combine the advantages of layered materials and 1D nanomaterials,which has attracted intense interest not only in the academic research but also in the industrial *** sodium vanadate nanowires have received incremental attention due to the high capacity and enhanced electrical conductivity for promising advanced energy storage and conversion. however, the mass production of these 1D layered vanadium vanadates(1D NVO) are still of great challenge and the further scalable application in energy storage and conversion systems are hampered. herein, we developed a facile, non-hydrothermal, green synthesis strategy for scalable, mass production of layered vanadium vanadate nanowires and their assemblies such as membranes, blocks, grains, powders toward industrial scale. It will pave a way for the industrial production of 1D inorganic materials and give a new insight into the fabrication of nanostructured materials beyond commercialized 1D/2D nanomaterials including carbon nanotubes(CNT) and layered double hydroxides(LDh).

On September 23, the 2016 Lasker-DeBakey clinical medical research award ceremony was celebrated in New York City. This annual prize has been awarded by the Lasker Foundation for over 71 years, and it is the most prestigious biomedical award in the United States, popu- larly known as ＂America＇s Nobel Prize＂. Indeed, 87 Lasker laureates have received the Nobel Prize, including 41 within the last 30 years （one example is the Chinese pharmaceutical chemist Youyou Tu, who won the 2011 Lasker-DeBakey award and four years later received the Nobel Prize）. This year, the honor went to Ralf F. W. Bartenschlager （heidelberg University, Germany）, Charles M. Rice （Rockefeller University, NY, USA）, and Michael j. Sofia （Arbutus Biopharma, PA, USA） for the development of cell culture system to study the replication of hepatitis C virus （hCV） and for the use of this system to develop drugs capable of eliminating hepatitis C.

niTi particles reinforced aluminum （niTip/Al） composite was prepared via friction stir processing, elimi- nating interfacial reaction and/or elemental diffusion. The niTip in the composite maintained the intrinsic characteristic of a reversible thermoelastic phase transformation even after heat-treatment. The shape memory characteristic of the niTip decreased the coefficient of thermal expansion of the Al matrix, and an apparent two-way shape memory effect was observed in the composite. The composite owned a good combination of adjustable damping and thermal physical properties.
