BACKGROUND: Safety is a primary concern with contrast agents used for MRI. If precautions could be taken before the repeated administration of gadolinium-based contrast media, then the awareness and management of adverse reactions would be more efficient. OBJECTIVES: To assess the safety and efficacy of gadoterate meg…
In this contribution, we report on experiments performed in MAST to investigate dust creation, transport and influence on plasma performance. The exceptional diagnostic access of MAST allows stereoscopic imaging of dust particles' motion in both the divertor and the main chamber, utilizing fast infrared cameras. This…
A sterically stabilized, mitoxantrone-loaded liposome, tailored to target luteinizing hormone-releasing hormone (LHRH) receptor overexpressing cells, was developed to promote the efficiency of intracellular delivery of mitoxantrone through receptor-mediated endocytosis. Liposomes were prepared by lipid film hydration…
A new method for synthesizing alumina (Al 2 O 3 ) nanofibers through the electrospinning method was reported. The spinning solutions of anhydrous aluminium chloride/polyvinylpyrrolidone (AlCl 3 /PVP), which were prepared by the sol-gel process of the mixture of AlCl 3, PVP, ethanol and redistilled water, were electros…
We study the steady flow properties of different three-dimensional aqueous foams in a wide-gap Couette geometry. From local velocity measurements through Magnetic Resonance Imaging (MRI) techniques and from viscosity bifurcation experiments, we find that these foams do not exhibit any observable signature of shear ban…
Date Palm Fiber (DPF) is one of the most available natural fibers in the Middle East, especially in Iran and the Persian Gulf region. This research provides a new insight into DPF, with consideration of morphological, chemical characteristics, and bulk density, as well as morphological and mechanical properties of DPF…
A nonlinear thermodynamic model is used to investigate the influence of thermal stresses on the room temperature (RT) pyroelectric properties of (001)-textured polycrystalline barium strontium titanate (BaxSr1−xTiO3, BST) films with four different compositions on three integrated circuit-friendly substrates: Si, (0001…
In the past two decades, nanotechnology has made great progress in generating novel materials with superior properties. Quantum dots (QDs) are an example of such materials. With unique optical properties, they have proven to be useful in a wide range of applications in life sciences, especially as a better alternative…
This article highlights the scientific evidence to date on a variety of nanotechnology issues important to consumers with a focus on food applications. Nanotechnology is technology at the atomic or macromolecular levels on the scale of approximately 1–100 nm. There are unlimited potential applications of nanotechnolog…

Naphthobipyrrole is a potentially useful building block for porphyrin and porphyrin analogue synthesis. Reported here is a simple, generalizable synthetic route to α-formylated, β-substituted naphthobipyrroles and their use in the preparation of binaphthoporphycenes. The resulting binaphthoporphycenes possess a planar…
Magnetic core loss is an emerging concern for integrated POL converters. As switching frequency increases, core loss is comparable to or even higher than winding loss. Accurate measurement of core loss is important for magnetic design and converter loss estimation. And exploring new high frequency magnetic materials n…
BiFeO 3 (BFO) films were formed on (001), (110), and (111) La-doped SrTiO 3 single-crystal substrates. All the films were epitaxially grown and had mainly rhombohedral structure. The BFO film formed on the (001) substrate had only a (001) component whereas the BFO films on (110) and (111) substrates had (110) and (111…
In this paper we present a direct measurement of stretched chain conformation in polymer nanocomposites in a large range of deformation using a specific contrast-matched small angle neutron scatttering (SANS) method. Whatever are the filler structure and the chain length the results show a clear identity of chain defo…
The existence of bound states in the continuum was predicted at the dawn of quantum mechanics by von Neumann and Wigner. In this work we discuss the mechanism of formation of these exotic states and the feasibility to observe them experimentally in symmetrical heterostructures composed by segments of graphene ribbons…
Thermoplastic polyurethane (TPU)/functionalised graphene sheet (FGS) nanocomposites were prepared by an in situ polymerisation method. The synthesised TPU/FGS nanocomposites were fully characterised by FT-IR, TEM, TGA, DSC, DMA, and by measurements of electrical conductivity and mechanical properties. The results indi…
A simple, cost-effective yet rapid and sensitive sensor for on-site and real-time Hg(2+) detection based on bovine serum albumin functionalized fluorescent gold nanoparticles as novel and environmentally friendly fluorescent probes was developed. Using this probe, aqueous Hg(2+) can be detected at 0.1 nM in a facile w…
Nanosized particles (NPs) have recently been proposed for extensive use, including into the biomedical field. As a result, research on toxicity and oxidative stress concerning the interaction of nanoparticle and the living organism has attracted increasing interest among specialists. Two different targets have been th…
Glasses are commonly synthesized by cooling melts at a rate sufficient to prevent the nucleation of substantial amounts of crystalline phases. In the limit, high cooling rates no longer prevent crystallization. In some of these cases, elimination of container‐melt‐induced nucleation by using containerless processing (…
Combined small and wide angle synchrotron x-ray scattering (SAXS and WAXS) techniques have been developed for in situ high pressure samples, enabling exploration of the atomic structure and nanoscale superstructure phase relations. These studies can then be used to find connections between nanoparticle surfaces and in…
