Dynamic load on composite laminates in the presence of water

23.03.2017 | V. Lopresto, A. Langella, I. Papa, Polymer Engineering and Science, 2017

An experimental activity, in order to assess the impact behavior at room and low temperature, of carbon fiber in vinylester resin laminates used in the shipbuilding industry, was conducted. The conditions, which simulate the impact of a tool that drop on the panel mounted on a boat hull in ...

Electric Field Induced Assembly of Ag Nanoparticle on CuO Nanowire by Ambient Electrospray Ionization

23.03.2017 | Hairui Fang; Dong Wang; Long Yuan; Xiaofeng Wu; Hongping Guo; Huanwen Chen; Keke Huang; Shouhua Feng, New Journal of Chemistry, 2017

We report a room temperature synthetic route of a dandelion-like CuO-Ag hybrid hierarchical nanostructure through electric field induction of electrosprayed Ag ions or clusters. The basic preparation process covers producing charged Ag clusters by atmospheric pressure ionization, soft-landing and ...
