Owing to its well-known chemical stability, thermal and complementary metal-oxide-semiconductor process compatibility, titanium nitride (TiN) has recently been demonstrated as an excellent alternative plasmonic material for noble metals. However, the lack of systematic studies on electromagnetic enhancement mechanism placed obstacle realization localized surface plasmon resonance (LSPR) using this unique TiN substrate surface-enhanced Raman scattering (SERS) applications. In study, we...
The dynamic recrystallization (DRX) and phase transformation (PT) behavior of a wrought β-γ TiAl alloy during hot compression under various deformation temperatures were investigated. typical work hardening flow softening features indicated that DRX was the dominating mechanism. Both γ-DRX β-DRX took place compression. triggered at all temperatures, while induced when temperature above 1000 °C. kinetics calculated, which showed existed in whole process, volume fraction increased with...
To enlarge the surface-enhanced Raman scattering (SERS) enhancement of Ag nanopillar arrays, a well-controlled armrest NRs@Al2O3 structure was designed, aiming at triggering efficient resonance between and NRs. A series with well-designed morphology as well enhanced "hot spots" quantity by taking advantage AAO template oblique angle deposition were successfully fabricated. Both experimental results numerical simulations revealed localized surface plasmon (LSPR) tunability simply optimizing...
Surface-enhanced Raman spectroscopy (SERS) has been utilized for rapid analysis of uranyl ions (UO22+) on account its fast response and high sensitivity. However, the difficulty fabricating a suitable SERS substrate in situ severely restricts practical application. Hence, we proposed flexible adhesive tape decorated with silver nanorod (AgNR) arrays detection UO22+. The was fabricated through simple "paste & peel off" procedure by transferring slanted AgNR from silicon to transparent...
Rapid alternating stress is formed in structure subjected to harsh thermal-acoustic loads, which will affect fatigue performance and reduce life seriously. First, experiment of superalloy thin-walled was carried out obtain damage location failure time the specimen, S-N curves at 723 K were fitted. Then, dynamic response simulation under same load as implemented, estimated based on prediction model mainly included: improved rain-flow counting method, Morrow average Miner linear cumulative...

We proposed two physical concepts, i.e., an intramolecular relative cross section (RCS) and intermolecular scattering ability (RSA), to re-understand re-describe surface-enhanced Raman (SERS) established a general SERS quantification theory. Interestingly, RCS RSA are intrinsic factors experimentally measurable form datasheets of molecules, namely, cards, with which standard procedure was established. The validity the theory confirmed by experiments. Surprisingly, also valid for complex...
Aluminum has been established as an earth-abundant and low-cost alternative to gold silver for plasmonic applications. Particularly, aluminum largely tends combines with oxygen compared silver. Here, a simple glancing angle deposition technique is presented prepare Ag-Al alloy nanorods (NRs) small amount of aluminum. The effect combine or corroded substances under certain conditions, such in the air etchants. Beside this, owing large diffusion coefficient Si wafer, diffuses easily into so...
Shadow sphere lithography (SSL) is a powerful and large-scale fabrication method to produce two-dimensional (2D) plasmonic photonic crystals three-dimensional metamaterials. Practically, one of the biggest challenges for SSL-based fabrications that it hard accurately predict physical properties fabricated nanostructures if structures were only modeled by geometric shadowing effect. A Monte Carlo (MC) simulation developed show dynamic effect due accumulation materials on template as well...
Silver (Ag) nanostructures are active functional platforms for catalysts, optical sensors, and transparent conductive networks with outstanding performance but present poor stability depending on their chemical, mechanical, or thermal surroundings. Doping other elements passivation a chemically inert coating of Ag nanostructure proven to be efficient in enhancing the stability, while both methods have drawbacks such as cost sacrifice on-demand properties. Here, we self-passivated Ag–Al...
