Dissolving microneedles (DMs) were applied to glucose monitoring in the dermal interstitial fluid (ISF) of rats and their potential as an alternative blood glucose monitoring device was evaluated. Sodium chondroitin sulfate was used to prepare DM array chips, which consisted of 300 DMs/cm(2). The mean length of the DMs was 475±18 µm and the mean diameter of(More)
In this paper, we present experimental results of frequency scaling and transducer optimization in internal dielectrically transduced silicon bar resonators. We show that selective positioning of the dielectric transducers inside the resonator can preferentially excite targeted harmonics while suppressing undesired modes. Furthermore, measurements across(More)
This paper presents a study of mechanical coupling in 2D resonator arrays for filter applications. A robust coupling design for 2D array filters, comprised of weak coupling in one dimension and strong coupling in the second, is demonstrated experimentally and compared with weakly coupled and electrically summed 2D resonator array filters. Effects of(More)
We present the design, fabrication, and evaluation of a large total-reflection mirror for focusing x-ray free-electron laser beams to nanometer dimensions. We used an elliptical focusing mirror made of silicon that was 400 mm long and had a focal length of 550 mm. Electrolytic in-process dressing grinding was used for initial-step figuring and elastic(More)
The Cerium-doped Gd2SiO5 single crystal (GSO) is a material which is increasingly being employed for the scintillators used in nuclear medical diagnose such as positron emission tomography (PET). However, such characteristics as poor machinability and difficulty in achieving efficient quality machining have impeded the rapid increase in the use of GSO. In(More)
Reflective optics is one of the most useful techniques for focusing a neutron beam with a wide wavelength range since there is no chromatic aberration. Neutrons can be focused within a small area of less than 1 mm 2 by high-performance aspherical supermirrors with high figure accuracy and a low smooth substrate surface and a multilayer interface. Increasing(More)
We have investigated the microwave-detected photoconductivity responses from the amorphous In–Ga–Zn–O (a-IGZO) thin films. The time constant extracted by the slope of the slow part of the reflectivity signals are correlated with TFT performances. We have evaluated the influences of the sputtering conditions on the quality of a-IGZO thin film, as well as the(More)
An aspherical supermirror is one of the most useful neutron-focusing optics. We aim to develop multiple aspherical supermirror devices using high-precision figured aspherical focusing supermirrors to focus neutron beams with high intensities, because multiple mirrors collect a very large beam divergence. Thin mirrors with a millimeter thickness are required(More)
Microwave photoconductivity decay (μ-PCD) method was applied to evaluate the effects of chemical composition and Ar plasma induced damage on the bulk and the surface states in amorphous In-Ga-ZnO (a-IGZO) films. It was found that the peak reflectivity signal in the photoconductivity response increased with decreasing the Ga content, and had a strong(More)
