White upconversion (UC) luminescent materials have shown incomparable advantages over other light sources in the fields of solid-state lighting, liquid crystal display, and bioimaging, received extensive attention from researchers. In this work, a series microcrystals doped with different ion concentrations is synthesized by hydrothermal method, such as NaYF<sub>4</sub>: Yb<sup&g...

This work reports how to tune the semi-crystallinity of a blended microcrystalline cellulose/silk-fibroin biocomposite using ionic liquids and various coagulation agents. The morphological thermal properties 1:1 polymeric system are studied as function polymer fabrication parameters. Ionic liquids, 1-ethyl-3-methylimidazolium acetate verses chloride, used competing solvent types six hydrogen pe...

Secondary oxalosis causing acute kidney injury (AKI) has been widely reported in native kidneys but its occurrence in allograft kidneys is relatively uncommon. We present three patients with acute kidney allograft dysfunction secondary to tubular oxalate microcrystal deposits confirmed on allograft biopsy in the setting of acute gastrointestinal dysfunction. These three patients presented with ...

In this article, we investigate how the photonic band gaps and the variety of band dispersions of photonic crystals can be utilized for various applications and how they further give rise to completely novel optical phenomena. The enhancement of spontaneous emission through coupled cavity waveguides in a one-dimensional silicon nitride photonic microcrystal is investigated. We then present the ...

Encapsulant is one determining factor underpinning the device lifetimes of organic optoelectronics. However, encapsulant seriously needs improvement in optical, thermal, and mechanical properties, especially to develop organic light emitting diodes. In this study, we prepared an in situ crosslinked organosilane composite containing benzyloxy and glycidyl-modified quartz microcrystal (mQMC) as h...

A method to grow high quality, single crystalline semiconductor material irrespective of the substrate would allow a cost-effective improvement to functionality and performance of optoelectronic devices. Recently, a novel type of substrate-insensitive growth process called Evolutionary Selection Selective Area Growth (ES-SAG) has been proposed. Here we report the use of X-ray microdiffraction t...

Time-resolved interferometry, surface light-scattering imaging, and optical microscopic imaging have been developed and applied to research on amorphous and multicrystalline films upon intense pulsed excitation. Nanosecond interferometry of neat polystyrene film gives interesting expansion dynamics followed by complete recovery. Femtosecond surface light-scattering imaging reveals the roughenin...

A number of workers have estimated surface tensions of solids from measurements of the differences in the lattice parameters of bulk crystals and microcrystals. The data are then analysed by an expression valid only for spherical. isotropic microcrystals. Real microcrystals are usually facetted, resulting in a number of possible problems which are discussed here. The main results given are : (i...

BL-17A is a new structural biology beamline at the Photon Factory, Japan. The high-brilliance beam, derived from the new short-gap undulator (SGU#17), allows for unique protein crystallographic experiments such as data collection from microcrystals and structural determination using softer X-rays. However, microcrystal experiments require robust beam stability during data collection and minor f...

Silicon (Si) films were obtained through aluminothermic reduction of the quartz (SiO 2 ) substrates, where surface in contact with deposited aluminum (Al) layer has been converted to film Si during high-temperature annealing following reaction. X-ray diffraction (XRD) patterns and Raman spectra show dominating peaks corresponding elemental films. Energy dispersive spectroscopy (EDS), as well XR...
