Abstract The uniaxial tensile tests were carried out at temperature ranging from room temperature (RT) to 523 K under strain rates of 0.001, 0.010 and 0.100 s −1 to obtain the flow stress of AZ31B magnesium alloy. The tensile tests were simulated by the finite element method (FEM) to calculate the critical damage valu…
In recent years, chemotherapy with caffeine has manifested potently high efficacy against osteosarcoma, although adverse effects have been observed. Recently, we developed a novel drug delivery system (DDS) with nonionic vesicles prepared from Span 80 which have promising physicochemical properties as an attractive po…
Passive cavitation detectors are widely used for measuring acoustic emissions from cavitating bubbles. Acoustic emissions related to the dynamics of oscillating bubbles contain complex time and frequency domain information. Signal processing techniques traditionally used to analyse transient and stationary signals may…
We address the origin of beadlike edge states observed by scanning tunneling microscopy (STM) in moiré patterns of graphite. Low-bias STM measurements indicate these edge states are centered around AB stacking sites, contrary to the common assumption of them being at AA sites. This shift in the beads intensity with re…
Gold nanoparticles (AuNPs) have been used extensively as surface-enhanced Raman spectroscopic (SERS) substrates for their large SERS enhancements and widely believed chemical stability. Presented is the finding that iodide can rapidly reduce the SERS intensity of the ligands, including organothiols adsorbed on plasmon…
This study investigates the control of Ga doping in ZnO nanorods (NRs) grown on an amorphous ZnO-seeded glass substrate through hydrothermal method. ZnO was doped with various Ga concentrations (0.25, 0.5, and 1 mM). The average lengths of the resulting NRs were approximately 2.36, 1, and 1.5 μm, respectively, and the…
Nonlocal elasticity theory is presented for the free vibration and bending analysis of nano-scaled graphene sheets having a sector shape. An eight-node curvilinear domain is used for transformation of the governing equation of motion of sector graphene from physical region to computational region in conjunction with t…
All solid electrochromic devices (ECDs) were prepared using Prussian blue (PB) as electrochromic layer, CeO2-TiO2 as counter electrode and poly(vinylidene difluoride) (PVDF) as ionic conductive membrane. The electrodeposited PB films were characterized by ellipsometry and the thickness, roughness and refractive index…
In this work, the mechanical properties and microstructural features of an AISI 304L stainless steel in two presentations, bulk and fibers, were systematically studied in order to establish the relationship among microstructure, mechanical properties, manufacturing process and effect on sample size. The microstructure…
The electromagnetic shielding effectiveness (EMSE) of herringbone, whipcord, barathea, and crêpe woven fabrics, which are twill and sateen derivatives, woven with textured steel yarns has not been investigated so far. Therefore, in this research, textured stainless steel yarn, which has soft feeling and flexibility, r…
Intra- and intermolecular interactions of star polymers in dilute solutions are of fundamental importance for both theoretical interest and hierarchical self-assembly into functional nanostructures. Here, star micelles with a polystyrene corona and a small ionic core bearing platinum(II) complexes have been regarded a…
The corrosion behaviour of AE42 magnesium alloy and its composites reinforced with Saffil short fibres and SiC particles in various combinations was investigated. The corrosion rate of the unreinforced alloy was the lowest. The composite reinforced with Saffil short fibre alone exhibited slightly lower corrosion rate…
The urchin-like NiCo2O4 nanostructures were synthesized by a mild hydrothermal method. A possible growth mechanism is proposed based on the morphology evolution process upon reaction time. The effect of the concentration of metal salt on the electrochemical performance was investigated. The high electrochemical perfor…
Spatial control of the conductivity of poly(3,4-ethylenedioxythiophene)-poly(styrenesulfonate) (PEDOT:PSS) is demonstrated through the use of ultraviolet (UV) exposure. With appropriate UV exposure, electrical characterization shows that the in-plane sheet resistance of PEDOT:PSS films is increased by 4 orders of magn…
Zinc oxide nanostructures are interesting nanomaterials with a wide range of applications. Since the physical and<br /> chemical properties of ZnO nanoparticles are influenced both by their shape and size, a control of morphology<br /> of ZnO structures is needed for their commercial usage. Different chemi…
Abstract A hierarchically porous Sr 2 Fe 1.5 Mo 0.5 O 6− δ –Gd 0.1 Ce 0.9 O 1.95 (SFM–GDC) ceramic anode‐supported solid‐oxide fuel cell with a GDC electrolyte film was fabricated by freeze‐drying tape‐casting and drop coating. 3D X‐ray computed tomography analysis indicated that the SFM–GDC anode has a high porosity…
A simple method to prepare multifunctional liquid marbles and dry water with magnetic, color, and fluorescent properties is presented. Multifunctional liquid marbles were prepared by encapsulation of water droplets using flocculated polymer latexes. First, the emulsion polymerization reaction of polystyrene and poly(b…
The use of personal protective gear made from omniphobic materials that easily shed drops of all sizes could provide enhanced protection from direct exposure to most liquid-phase biological and chemical hazards and facilitate the postexposure decontamination of the gear. In recent literature, lubricated nanostructured…
This work aims to reduce the prices of a wide range of nanomaterials which are unreachable in the industry by using natural sources as silicon and aluminum precursors. In a previous work, silicon and aluminum have been extracted from Volclay after applying the alkaline fusion process at 550 °C, and a water treatment o…
Metastable Ge 4 Bi 2 Te 7 is highly disordered; the average structure corresponds to the rocksalt type. The diffraction pattern shows diffuse streaks interconnecting Bragg reflections along all cubic 〈111〉 directions. These streaks exhibit satellite-like maxima and arise from vacancy ordering in non-periodically space…
