Using scanning electron microscopy, X-ray diffraction, photoelectron spectroscopy CFT-I surface synthesizer, phase composition, element distribution friction properties coating analyzed to obtain best c...

This study has investigated the solubility of inhibiting pigments and also the leaching behaviour of corrosion inhibitors from a polyester binder in an acid rain solution. This study has relevance to the control of cut-edge corrosion by inhibitor pigments, which are incorporated into the primer coatings of coil-coated architectural cladding. The concentrations of leachate solutions in tubes glu...

We present a full-polymer respiratory monitoring device suited for application in environments with strong magnetic fields (e.g., during an MRI measurement). The sensor is based on the well-known evanescent field method and consists of a 1 mm plastic optical fiber with a bent region where the cladding is removed and the fiber is coated with poly-dimethylacrylamide (PDMAA). The combination of ma...

Laser cladding technology is used to clad the surface layer of H13 mold steel with Ni60A metal powder coating solve failure problem. The study JMatPro software extract and fit thermophysical property parameters substrate material, then ANSYS APDL qualitatively analyze distribution melt pool morphology, nodal temperature versus time course curve residual stress magnitude during laser process.

A large-mode-area polymer photonic crystal fiber made of polymethyl methacrylate with the cladding having only one layer of air holes near the edge of the fiber is designed and proposed to be used in surface plasmon resonance sensors. In such sensor, a nanoscale metal film and analyte can be deposited on the outer side of the fiber instead of coating or filling in the holes of the conventional ...

As-produced Cr-coated Optimized ZIRLO™ cladding material fabricated with the cold-spray (CS) deposition process is studied. Cross-sectional electron microscopy, nano-hardness profiling, transmission Kikuchi diffraction, and atom probe tomography (APT) were performed to investigate nature of CS Cr-coating/Optimized interface, microstructure coating, effects on Zr-substrate microstructure. The fo...

Ti5Si3 is an attractive light weight reinforcement phase in hypereutectic Ti–Si-based alloys, however, the proeutectic Ti5Si3 phase is brittle and is easily coarsened when the alloy is prepared under normal solidification conditions, thereby limiting its engineering applications in the aviation and biological industries. In this study, a hypereutectic Ti–20%Si coating with a pseudo-eutectic α-T...

We explore the possibility of coating semiconductor nanowires with metal (Ag) to reduce the size of nanowire lasers operating at photon energies around 0.8–2 eV. Our results show that the material gain of a typical III-V semiconductor in nanowire may be sufficient to compensate Joule losses of such metal as Ag. The most promising mode to achieve lasing seem to be TM01 near its cutoff. To calcul...

In this paper, we propose a small-diameter polarization-maintaining solid-core photonic crystal fiber. The coating diameter, cladding diameter and other key parameters relating to the thermal properties were studied. Based on the optimized parameters, a fiber with a Shupe constant 15% lower than commercial photonic crystal fibers (PCFs) was fabricated, and the transmission loss was lower than 2...

A relative humidity (RH) sensor based on single-mode-no-core-single-mode fiber (SNCS) structure is proposed and experimentally demonstrated. The agarose gel is coated on the no-core fiber (NCF) as the cladding, and multimode interference (MMI) occurs in the SNCS structure. The transmission spectrum of the sensor is modulated at different ambient relative humidities due to the tunable refractive...
