Equivalent circuit for VO2 phase change material film in reconfigurable frequency selective surfaces

Varittha Sanphuang ; Nima Ghalichechian ; Niru K. Nahar ; John L. VolakisAbstractWe developed equivalent circuits of phase change materials based on vanadium dioxide (VO2) thin films. These circuits are used to model VO2 thin films for reconfigurable frequency...

Norfloxacin-loaded collagen/chitosan scaffold for skin reconstruction: Preparation, evaluation and in-vivo wound healing assessment

Azza A. Mahmoud ; Alaa H. SalamaAbstractBiomaterial scaffolds are versatile tools as drug carrier for treatment of wounds. A series of norfloxacin-loaded scaffolds were synthesized for treatment of wounds by combining collagen with two different types of chitosan...

High-Temperature H2O Vapor Measurement Using Terahertz Spectroscopy for Industrial Furnace Applications

Song, Y. ; Wang, Z. ; Loh, J. ; Thomson, M.J.AbstractWe verified that high-temperature (773 K) H2O vapor can be measured quantitatively with terahertz (THz) spectroscopy in the frequency range of 0.5-0.8 THz. The linear relationships between the absorbance peak area...

Terahertz filter integrated with a subwavelength structured antireflection coating

Jeong Min Woo ; Dae-Seon Kim ; Dong-Ju Kim ; Jae-Hyung JangAbstractMicro-pyramid shaped subwavelength structures (SWSs) were integrated on both sides of a terahertz (THz) filter by means of stamping methods. Two silicon-based stamping molds fabricated via...

Terahertz Time-Domain Spectroscopy for Studying Absorbable Hemostats

Nedvedova, Marie, Vojtech Kresalek, Zdenek Adamik, and Ivo Provazník.AbstractThis study deals with the kinetics of absorbable hemostats used for supporting the hemostasis and wound closure during surgical intervention. There are several types of hemostats of different...

A Review of Disintegration Mechanisms and Measurement Techniques

Markl, Daniel, and J. Axel Zeitler.AbstractPharmaceutical solid dosage forms (tablets or capsules) are the predominant form to administer active pharmaceutical ingredients (APIs) to the patient. Tablets are typically powder compacts consisting of several different...
