Determination of GIC in Angle Ply Composites Using a Cantilever Beam Test Method

Abstract: A double cantilever beam test is used to measure GIC values in angle ply composites. It is demonstrated that the GIC values determined with this method are independent of the compliance of the spec...

Enhancing Heat Capacity of Colloidal Suspension Using Nanoscale Encapsulated Phase-Change Materials for Heat Transfer

Abstract: This paper describes a new method to enhance the heat-transfer property of a single-phase liquid by adding encapsulated phase-change nanoparticles (nano-PCMs), which absorb thermal energy during solid−liquid phase changes. Silica-encapsulated indium nanoparticles and polymer-encapsulated paraffin (wax) nanoparticles have been made using colloid method, and suspended into poly-α-olefin (PAO) and water for potential high- and low-temperature applications, respectively. The shells prevent leakage and agglomeration of molten phase-change materials, and enhance the dielectric properties of indium nanoparticles. The heat-transfer coefficients of PAO containing indium nanoparticles (30% by mass) and water containing paraffin nanoparticles (10% by mass) are 1.6 and 1.75 times higher than those of corresponding single-phase fluids. The structural integrity of encapsulation allows repeated use of such nanoparticles for many cycles in high heat generating devices.

Efficient grating-tuned mid-infrared Cr2+:CdSe laser.

Abstract: Room-temperature, all-solid-state, broadly tunable laser operation of Cr2+-doped CdSe has been demonstrated. Pumping with a Q-switched Tm, Ho:YLF laser running at a 1-kHz repetition rate achieved broadband output of 500 mW at 2.6 µm with 48% absorbed power slope efficiency. With reduced efficiency, as much as 815 mW of power was obtained. With a diffraction grating, the Cr2+:CdSe laser was tuned from 2.3 to 2.9 µm with 10-nm bandwidth (FWHM) and output power up to 350 mW.

Aminopropyltriethoxysilane (APTES)-functionalized nanoporous polymeric gratings: fabrication and application in biosensing

Abstract: We have fabricated aminopropyltriethoxysilane (APTES)-functionalized nanoporous polymeric gratings by combining holographic interference patterning and APTES-functionalization of the pre-polymer syrup. The APTES facilitates the immobilization of biomolecules onto the polymeric grating surfaces. The successful detection of multiple biomolecules (biotin, steptavidin, biotinylated anti-rabbit IgG, and rabbit-IgG) indicates that the functionalized nanoporous polymeric gratings can act as biosensing platforms which are label-free, inexpensive, and applicable as high-throughput assays.
