Accelerated pharmacokinetic map determination for dynamic contrast enhanced MRI using frequency-domain based Tofts model
Dynamic Contrast Enhanced Magnetic Resonance Imaging (DCE-MRI) is widely used in the diagnosis of cancer and is also a promising tool for monitoring tumor response to treatment. The Tofts model has become a standard for the analysis of DCE-MRI. The process of curve fitting employed in the Tofts equation to obtain the…
Similarities of arterial collagen pressure-diameter relationship in ovine femoral arteries and PLLA vascular grafts
INTRODUCTION: In-vivo implanted vascular grafts fail due to the mechanical mismatch between the native vessel and the implant. The biomechanical characterization of native vessels provides valuable information towards the development of synthetic grafts. MATERIALS AND METHODS: Five samples of electrospun nanofibrous p…

Formaldehyde-Free Wood Composites from Soybean Protein Adhesive
Commercial particleboards are currently synthesized by blending wood furnish with formaldehyde-based resins and curing them under a combination of heat and pressure. Particleboards manufactured with urea-formaldehyde resin are known to liberate formaldehyde during their service lives. Formaldehyde’s carcinogenicity ha…

Cicada wing with adhesive superhydrophobicity and their biomimetic fabrication
Cicada is hymenoptera insect. It is found that cicada wing exhibit super-hydrophobicity and a high adhesive force with water, which is different from lotus leaf. The water contact angle (WCA) on cicada wing is 145.81±4.83°. The water droplet does not slide on the cicada wing surface when the surface is tilted at 90°.…
Performance optimization of a solid oxide fuel cell-stirling heat engine hybrid power system
Based on the theory of the electrochemistry, non-equilibrium thermodynamics and finite-time thermodynamics, a new theoretical model of the hybrid power system consisting of an existing solid oxide fuel cell and a Stirling heat engine is established, in which some main irreversible losses existing real hybrid systems a…
Finite element method and experimental modal analysis of PMLSM for ropeless elevator
Modal analysis is a technology for vibration characteristic research. It is the foundation for structural dynamics analysis. Natural frequency is a very important performance in dynamics analysis. Modal characteristics of the Permanent Magnet Linear Synchronous Motor (PMLSM) for ropeless elevator were investigated by…

Preparation and Visible-Light Photocatalytic Activity of Cu2O/PVA/Chitosan Composite Films
Cu2O/PVA/chitosan composite films were prepared successfully by reduction-precipitation method and tape casting process. The composite films were characterized by TEM, SEM, XRD and FT-IR. The characterization results showed that Cu2O particles were 200-300 nm in diameter and in situ formed on PVA-chitosan blend films.…
Formation of Tsai-type 1/1 approximants in In-Pd-RE (RE: rare earth metal) alloys
The formation of the 1/1 crystal approximant phase (1/1 phase) to the icosahedral phase (i phase) in In-Pd-RE (RE: rare earth metal) systems has been investigated. A new series of 1/1 phases were found in In53Pd33RE14 (RE; Y, Ce, Pr, Nd, Sm, Gd, Tb, Dy, Ho, Er, and Tm) alloys. For Y, Sm, Gd, Tb, Dy, and Ho, the 1/1 ph…

Green colouring electrochromic devices of water-soluble polythiophene
The authors report on the electrochromic (EC) behaviour of the environmentally friendly water-soluble polythiophene sodium poly (2-(3-thienyl) ethoxy-4-butylsulfonate) (PTEBS) solid-state devices. Films are fabricated on indium tin oxide substrates and are composed of bilayers of PTEBS and poly (allylamine hydrochlori…

Anodic Porous Alumina Array for Cyanine Fluorophore Cy3 Confinement
Self-organized anodic porous alumina films with hexagonal pore lattice have attracted a considerable attention for biological arrays and confinement of various organic probes dyes in solutions. A molecular structure with axialsymmetry in bis-heterocyclic indole chains and conjugate system, such as cyanine fluorophore…
Modeling Methodology for Stress Determination by XRD in Polycrystalline Materials
To get a quantitative estimate of residual stresses in polycrystals from XRD measurements, a micromechanical modeling is required, except in particular cases. The most widely used method is only valid for homogeneous and isotropic samples. We present here the possibility to determine residual stresses by coupling meas…
