This study is focused on 3D printing of polyamide 6 (PA6), PA6/graphene oxide (PA6/GO) and PA6/glass-fibre-reinforced (PA6/GF) composites. The effect graphene glass-fibre reinforcement 3D-printed PA6 explored for improvement the interfacial bond interlaminar strength in ambient, wet high temperature conditions relating to electric car battery box requirements. influence environmental process pa...

Derivative structural polytypes coexisting with the rhombohedral A7 structure of elemental bismuth (Bi) have been discovered at ambient condition, based on microstructure analyses of pure Bi samples treated under high pressure and high temperature conditions. Three structures with atomic positions close to those of the A7 structure have been identified through first-principles calculations, sho...

Random Decrement Technique (RDT) based decentralized computing approaches implemented in wireless sensor networks (WSNs) have shown advantages for modal parameters and data aggregation identification. However, previous studies of RDT-based approaches from ambient vibration data have usually assumed that the input excitation is a broad-band stochastic process modeled by stationary white or filte...

The oriented attachment of calcite, which is a main component of biominerals, was experimentally demonstrated in an aqueous system at ambient temperatures. Calcite nanoblocks 50 nm in size were prepared by carbonation of Ca(OH)2. One-dimensional (1D) alignment of the calcite nanoblocks was induced at ambient temperatures under a basic condition (pH 12), and single-crystalline rods over 1 mmwere...

Ammonia production via the electrochemical N2 reduction reaction (NRR) at ambient conditions is highly desired as an alternative to Haber-Bosch process, but remains a great challenge due low efficiency and selectivity caused by competing hydrogen evolution (HER). Herein we investigate effect of availabilities reactants (protons, electrons N2) on NRR using FeOx-coated carbon fiber paper cathode ...
