In this work, a YAG laser was used to clad TiC-reinforced metal matrix composite layers on the surface of different types of metals; low carbon steel, high C–Cr bearing tool steel, spheroidal graphite cast iron and commercially pure titanium. The cladding processes were carried out at heat inputs ranging from 175 J mm…
The in situ preparation of particle reinforced metal matrix composites (PRMMCs) can prevent the particle surface from pollution, improve the wettability of particles and matrix metals, and reduce the production cost of composites. In this paper, in situ Mg _2 Si reinforced hypereutectic Al-18%Si matrix composites were…
The corundum-structured seeds have been introduced into alumina films using Al + α -Al _2 O _3 composite and Al _100−x Cr _x (x = 10, 20, 30) alloy as targets by reactive magnetron sputtering. The effects of the seeds on the elemental composition, phase composition, structure characteristic, surface morphology and nan…
In this article, a 6 mm thick high-strength steel (HSS) was butt laser-MAG welded using nickel alloy wires as the cladding layer. By preparing the cladding layer on the groove, the microstructure and properties of the weld were adjusted. OM, XRD, SEM, and tensile and impact experiments were used to study the structure…
Dental whitening techniques and materials have become one of the most important non-surgical methods used to improve the appearance of teeth and to make them whiter and brighter, as well as to hide blemishes of the teeth. Since the veneer do not last forever and may fail due to fracture or adhesion failure or wrong se…
A ropelike LiNi _0.8 Co _0.15 Al _0.05 O _2 (NCA) fiber with superior rate capability and cycling stability was successfully synthesized via electrospinning and sintering as a cathode material for Li-ion batteries. The NCA fiber that exhibited excellent electrochemical performance as a cathode for Li-ion batteries was…
Recent advancement in antenna technology is directed to achieve reconfiguration of radiating structure parameters. In this paper, we propose graphene-based reconfigurable and high gain microstrip radiating structure for multiband wireless communication applications. The circular copper patch is used as a radiating ele…
Abstract The development of molecular/nanoscale level assemblies allows the foundation of many potential novel applications. Chemical approach is one of the most favoured techniques to manipulate the nano-materials in a controllable manner. Herein, we report a simple and reliable one pot technique for preparing graphe…
The Metal Matrix Composites (MMCs) are increasingly replacing the commercial alloys in engineering components and undergoing intense analysis in the development of advanced composite structures. The metal matrix composites exhibit superior mechanical and tribological behavior than alloys in wear critical applications.…
The performance of surface plasmon resonance (SPR) sensors can be different depending on which characteristic of the SPR sensor the amplitude or the phase is monitored. The phase sensitivity strongly depends on the geometry and the optical properties of the system. The existence of sharp changes in the phase spectrum…
Abstract Mesoporous tungsten oxide nanobricks (WO 3 NBs) are successfully prepared via a simple and cost-effective hydrothermal synthesis method. The as-synthesized WO 3 NBs demonstrate a high sensitivity and selectivity when used for liquid ammonia and humidity sensor activities at room temperature (27 °C). The monoc…
It is well-known that issues always occur for local non-hardenability of 1.5 GPa ultra-high strength steel plates during conventional hot forming processes, once the thickness of the plates is more than 2.5 mm. To resolve the issues, our recent research suggests that adding cerium during metallurgical processes is a p…
Two-dimensional (2D) materials have attracted extensive attention in various fields due to their good flexibility, high specific surface area and fast ion transfer rate. Herein, the α -Fe _2 O _3 nanoparticles/graphene composites have been prepared through a hydrothermal method, which is followed by hydrogen annealing…
In this work we studied the grain growth and orientation change of CdTe multi-crystallize thin films during chlorine activation. A thermodynamic energy criterion is proposed for finding non-toxic substitutes of cadmium chloride and tested by Monte-Carlo simulation method combined with CASTEP calculation and annealing…
The pressure or normal stress effect on the plastic yielding of metallic glasses (MGs) is still poorly understood due to their complex nature of deformation process. A knowledge on the internal stress distribution and evolution around the plastic shearing plane holds the key for understanding the above issue. In this…
Abstract Polycrystalline sodium lithium-cobalt-aluminum arsenate, Na 4 Li 0.62 Co 5.67 Al 0.71 (AsO 4 ) 6 , was synthesized by solid state reaction route and characterized by infrared spectroscopy (FT-IR), X-ray diffraction (XRD) and Inductively Coupled Plasma Mass Spectrometry (ICP-MS).

Besides that, the investigation into the effects of the Cr content on their corrosion behav…
The UV-aging tests were carried out on synthetic fluorinated polymer coating (poly (methyl methacrylate)-poly (dodecafluoroheptyl methacrylate), FP) to study its UV-aging mechanism, UV-aging resistance and application on painted muds with calcium carbonate, azurite, haematitum, mineral green and cinnabar pigments.

Cu _x S thin films were grown onto soda-lime glass substrates by pulsed laser deposition at two different wavelengths: 1064 and 532 nm. X-ray diffraction, Raman and UV–vis spectroscopies were used to characterize the Cu _x S films. Results are presented as a function of laser fluence. XRD patterns indicate that covell…
A laser cladding and friction stir processing hybrid method was employed to produce an Al matrix composite layer.
