Developing methods that evaluate the cellular uptake of magnetic nanoparticles (MNPs) and nanotoxicity effects at single-cellular level are needed. In this study, magnetophoresis combining fluorescence based cytotoxicity assay was proposed to assess the viability and the single-cellular MNPs uptake simultaneously. Mal…
Sub-micrometre high-performance Sr-ferrite powder was prepared by a molten-salt method using Na2SO4 as the fluxing agent. In the reaction process, a mixture of superfine powder was pre-sintered at 1150 °C for 3 h and then annealed at 850 °C for 2 h. The as-obtained Sr-ferrite powder is SrFe12O19 with a hexagonal magne…
In the present communication, the effect of water absorptions on mechanical properties of roselle fiber reinforced vinyl ester composites prepared by wet hand lay‐up method was studied. Water absorption tests were conducted by immersing composite specimens into three different water environments, namely distilled wate…
We present the design and fabrication of guided-mode resonant broadband reflectors operating in transverse electric (TE) polarization. The structure consists of a subwavelength one-dimensional grating with a two-part period and a nanometric homogeneous layer of amorphous silicon on a quartz substrate. A representative…
Abstract In this study, the effects of different oxygen‐containing group contents in thermally reduced graphene oxides ( TRGs ) for enhancing the physical properties of epoxy nancomposites was examined. The epoxy/ TRG nanocomposites ( ETNs ) were prepared by a room temperature curing method in the presence of TRGs con…
Ordered metal nanopatterns are crucial requirements for electronics, magnetics, catalysts, photonics, and so on. Despite considerable progress in the synthetic route to metal nanostructures, highly ordered metal nanopatterning over a large-area is still challenging. Nanodomain swelling block copolymer lithography is p…
We report the effect of isochoric confinement on the characteristic length of the glass transition (ξ α ) for polystyrene (PS) and poly(4-methylstyrene) (P4MS). Utilizing silica-capped PS and P4MS nanoparticles as model systems, ξ α values are determined from the thermal fluctuation model and calorimetric data. With d…
Advancing the understanding of microstructural effects and deformation on the degradability of Fe-Mn bioresorbable alloys (specifically, Fe-33%Mn) will help address the current problems associated with designing degradable fracture fixation implants for hard tissues. Potentiostatic polarization tests were conducted on…
Experimental evidences from transport, magnetic, and magneto-optical (MO) image measurements confirmed that arsenic (As) vapor annealing was another effective way to induce bulk superconductivity with isotropic, large, and homogenous superconducting critical current density (Jc) in Fe1+yTe0.6Se0.4 single crystal. Sinc…
The oxo-bridged heterobinuclear chromophore TiOMn 2+ has been covalently anchored onto a silica nanoparticle surface, allowing for the preparation of optically transparent solid state samples. Optical spectra of the material yield a broad metal-to-metal charge-transfer (MMCT) transition in the UV with a tail extending…
Sensitive and selective assay of collagen is of substantial importance to the diagnostic study of health- and aging-related failures. In this paper, we describe a highly specific and sensitive method for the assay of whole collagens in biological samples using a novel fluorogenic reagent, 3,4-dihydroxyphenylacetic aci…
Perlucin is one of the proteins of the organic matrix of nacre (mother of pearl) playing an important role in biomineralisation. This nacreous layer can be predominately found in the mollusc lineages and is most intensively studied as a compound of the shell of the marine Australian abalone Haliotis laevigata. A more…
ABSTRACT This article reports a new needleless emulsion electrospinning method for scale‐up fabrication of ultrathin core–shell polyacrylonitrile (PAN)/isophorone diisocyanate (IPDI) fibers. These core–shell fibers can be incorporated at the interfaces of polymer composites for interfacial toughening and self‐repairin…
Drug delivery systems based on nanofibrous mats appear to be a promising healing practice for preventing brain neurodegeneration after surgery. One of the problems encountered during planning and constructing optimal delivery system based on nanofibrous mats is the estimation of parameters crucial for predicting drug…
Effects of heat treatment on structure and physicochemical properties of zein (Ze) and gallic acid loaded zein (Ze-GA) electrospun fiber mats were investigated. The electrospun fiber mats displayed different surface and physicochemical properties after being heat-cured at 150 °C for 24 h, which were closely related to…
A comparative study of the wear behaviors of a selected titanium alloy and AISI H13 steel as a function of temperature and load was performed on a high-temperature wear tester. The titanium alloy and H13 steel presented totally different wear behaviors with the variation in temperature and load. Their behaviors are su…
This paper is concerned with the simulation of drying behavior of wool yarn bobbins and also determination of the optimum operating conditions by using thermodynamic analysis. Firstly, experimental drying behavior of wool yarn bobbins was determined on a hot-air bobbin dryer. Empirical and semi-empirical mathematical…
Single-lap polymeric joints can be obtained using laser welding overlapping two polymeric sheets, with one laser transparent and the other laser adsorbent. In this study we employed crystalline carbon nanomaterials (in amounts of 0.2, 0.5, and 1.0 wt.%) as filler to enhance the absorption of polyethylene (UHMWPE type)…
Biodegradable polymeric nanoparticles have attracted attention as potential drug delivery devices due to its bioavailability, biocompatibility, encapsulation, controlled drug release and in drug targeting to organs/tissues, as carriers of DNA in gene therapy, deliver proteins, peptides and genes. Controlled release sy…
Silk proteins represent a unique choice in the selection of biomaterials that can be used for corneal tissue engineering and regenerative medical applications. We implanted helicoidal multilamellar arginine-glycine-aspartic acid-functionalized silk biomaterials into the corneal stroma of rabbits, and evaluated its bio…
