Surface-enhanced Raman scattering (SERS) is a rapid and nondestructive spectroscopic method for trace detection. The enhancement based on both electromagnetic chemical mechanism requires the molecules to be in close contact with SERS-active material. Therefore, it difficult detect amounts of liquid directly. In this paper, graphene oxide (GO) Ag nanoparticles (AgNPs) are uniformly modified inner wall capillary. GO can provide by adsorbing analyte onto its flat surface producing efficient...
Microstructure fibers, integrating microfluidic channels and light guidance in one fiber, enable three-dimensional surface-enhanced Raman scattering (SERS) detection for large signal accumulation. However, the available fiber SERS probes are complicated to prepare they not reusable. In addition, interacts with analytes a form of an evanescent field, which is very weak. this paper, we developed platform based on suspended-core photonic crystal fibers decorated Ag/ZnO nanocomposites inner...
Abstract Nitrogen‐doped reduced graphene oxide (N‐rGO) was obtained via high temperature heat treatment using ammonia as a nitrogen source. EDS and XPS tests revealed that the atoms have been doped into skeleton of successfully. On this basis, hollow nanospherical cuprous supported by N‐rGO (HNS‐Cu 2 O/N‐rGO) synthesized chemical precipitation electrode materials for detection glucose. TEM test showed spherical has successfully on surface N‐rGO. In case electrochemical studies, HNS‐Cu...
Due to the refocusing optical feedback in silver-coated capillary, uniform SERS sensitivity across end face of large-size liquid channel is realized.
The development of Surface Enhanced Raman Scattering (SERS) promotes the wide application spectroscopy in chemical and biomolecular detection. SERS detection relies on analytes close contact with metallic surface, therefore direct molecular trace liquid phase is difficult. In this paper, static was performed simply using a capillary without pre-functionalization. Gold nanoparticles (AuNPs) an optimized size ensure localized surface plasmons resonance exciting laser light. Grazing incidence...
In this work, the surface of long-period fiber grating (LPFG) and polarization maintaining (PMF) is functionalized based on interaction between resonance wavelength external environment. LPFG coated with a 150 nm ZnSe/Co film fixed hollow bracket, prestressed, annealed many times. A highly sensitive liquid level sensor adjustable sensitivity, an measurement range, high early warning prepared. The waveguide layer controlled by humidity constructed filling...
<title>Abstract</title> The incorporation of MgO expansive agents and internal curing mechanisms has individually exhibited positive effects on mitigating shrinkage in Ultra-high performance concrete (UHPC), yet studies their synergistic remain scarce. This paper explores the utilization recycled sand as a substitute for quartz UHPC production, incorporating various reactive (Type R Type S) at concentrations 4%, 6%, 8% (by mass) into UHPC. primary objective is to investigate impacts these...
<title>Abstract</title> In order to analyze the effect of carbonated recycled coarse aggregate (RCA) on mechanical and chloride ion penetration resistance self-compacting concrete (SCC), (RCASCC) was prepared with RCA treated different admixtures (15%, 30%, 50%) carbonation pressures (0, 75 kPa, 150 kPa), tested for its compressive strength, flexural electric flux, pore structure micro-morphology were analyzed. The results show that substitution rate pressure have a significant strength...
