Amorphous alumina is hard but brittle like all ceramic type materials which affects durability under impact or scratch. Here we show that layers below 100 nm thickness when stacked with aluminum interlayers exhibit exceptional performances including toughness equal to 300 J.m−2 determined by on chip nanomechanics. This almost two orders of magnitude higher than bulk and any other thin coatings. In addition, a hardness above 8 GPa combines fracture strain 5%. The origin this superior set...
Plasmon-driven surface catalytic (PDSC) reaction in Ag/Au nanoparticle monomer or dimer-film gaps are experimentally and theoretically investigated, using enhanced Raman scattering (SERS) finite element method. The variation of SERS spectra different nano nanoparticle-film systems indicated the PDSC was largely depended on number nanoparticles. higher intensity p,p′-dimercaptoazobenzene (DMAB) nanogap because effective coupling induced image charge metal film hybridized plasmonic gap mode,...
Abstract In order to meet the increasing engineering requirements, ultra-early strength of sulphoaluminate cement (SAC)-based materials need be improved achieve road repair, rescue and other objectives. Graphene oxide (GO) 0.04 wt% was incorporated into SAC mortar prepare GO enhanced (GO-SAC). It found that compressive GO-SAC increased by 46.9% at age 6 hours, flexural 121.4% 100 minutes, compared with control mortar. The mechanism analysis based on characterization results derived from XRD,...
Abstract This study investigates the defect evolution mechanisms in nickel-based GH4169 superalloy fabricated using selective laser melting (SLM) under high-temperature fatigue. X-ray computed tomography (CT) was employed for three-dimensional characterization, and in-situ fatigue tests were conducted at 400°C. Initial defects found to be randomly distributed, primarily consisting of pores lack-of-fusion (LOF) defects, with 80% having an equivalent diameter smaller than 20 μm. Pores...
Straw fibers are renowned for their cost-effectiveness, sustainability, and durability. They represent a promising natural reinforcement option reactive powder concrete (RPC). This paper investigated the impact of straw on RPC’s workability, mechanical performance (mechanical strength flexural toughness), electrical properties (electrical resistance AC impedance spectroscopy curves). The fiber volumes ranged from 1% to 4.0% total RPC volume. Specimens were cured under standard curing...
