The effect of self-assembled barium titanate (BT) aggregates in polyvinylidene fluoride (PVDF) matrix on the α‐β phase transition was investigated. BT/PVDF composites were prepared with and without dispersant process. addition dispersants increased average secondary particle area (S) BT particles promoted BT/PVDF/BT hetero-interface. FT-IR showed that enhanced increasing S. Cole-Cole plot estim...

Inorganic-salt-induced morphological evolution of GdF3 crystals was demonstrated for the first time in a mild hydrothermal process. By varying the amount of inorganic salt, the GdF3 crystals could transform from uniform elliptic nanostructures to submicroplates. The increase of ionic strength, hindered diffusion of reactant ions, and selectively adsorption of barium cations were responsible for...

This paper presents an enhanced piezoelectricity based sensor for touch and temperature sensing. The sensor is realized over flexible polyimide film, making it suitable for application like e-skin. The sensing material is composed of Polyvinylidene Fluoride-Trifluoroethylene (PVDF-TrFE) and Barium Titanate (BaTiO3) nanoparticles. While, the piezoelectric polymer PVDF-TrFE ensures the flexibilit...

BACKGROUND The purpose of this study was to assess the feasibility of infrared (IR) spectroscopy for the simultaneous quantification of serum LDL-cholesterol (LDL-C) and HDL-cholesterol (HDL-C) concentrations. METHODS Serum samples (n = 90) were obtained. Duplicate aliquots (5 microL) of the serum specimens were dried onto IR-transparent barium fluoride substrates, and transmission IR spectra...

A/J mice, as compared to C57BL/6J (B6) mice, have a significantly greater total femoral mineral (ash) content which correlates with an increased femoral stiffness (resistance to deformation), but also with an increased brittleness (catastrophic failure). To determine if this whole bone variation in mineral content is indicative of significant mineral and/or matrix variation at the tissue level,...

Bismuth germanate (BGO) and barium fluoride (BaF2) scintillators are presently used in positron emission tomegraphy (PET) cameras. This study evaluates the important PET performance parameters of image resolution, true sensitivity, scatter background, accidental background, and realistic maximum radioactivity in the field of view for both BGO and BaF2 in an identical non-time-of-flight, whole-b...
