This paper demonstrates a dental pulp cell therapy method by using a mixture of a bioceramic materials, simvastatin and collagenase as a drug delivery bioceramic diluent. The drug releasing mechanism and speed are based on a natural diffusion of concentration differences and micro-pinhole sizes on the bioceramic cement, which is composed of the calcium phosphate cement (CPC) and calcium sulfate dihydrate (CSD) powders, respectively. The collagenase and simvastatin can release via the micro-pinhole channels from the cement to not only regenerate dental pulp stem cells but also stimulate the differentiation of pulp cells locally. Three different mixture ratios of CPC and CSD powders were characterized to study the relationship between pinhole sizes and releasing times and speeds. The mixture CPC/CSD ratio of 3:7, named CPC3CSD7, performs well release profile of the collagenase and simvastatin. The released simvastatin and collagenase are over 80 and 50 percentages, respectively. Furthermore, an in-vitro cell culture experiment was applied to identify the biocompatibility and cultured odontoblasts grown differentiated well on the cement surface.

In this article, we report a Field Effect Transistor (FET) with Aluminum doped graphene channel. The graphene is doped by spin coating a chemical dopant solution which tailored the electrical properties of graphene, such as transfer characteristics and output characteristics. The Doping of graphene was successfully verified by X-Ray photoelectron spectra (XPS) measurements. The testing results showed that the Dirac point (the value of gate to source voltage at which minimum value of drain to source current is attained) in transfer characteristics of Graphene Field Effect Transistor (GFET) shifted from VGS = 6.42 V to VGS = 40 V after doping. The slope of the output characteristics of GFET for VGS = 0 V increased from 3.56 to 5.44.

We have fabricated titanium nitride (TiN) thin films on sapphire substrates by pulsed laser deposition (PLD) technique, and excited surface plasmon polaritons (SPPs) on TiN thin films by energy transfer from dye molecules. The system was fabricated by depositing a thin polymer layer containing rhodamine 6G (R6G) on a TiN thin film, separated by a thin spacer made of silica. The SPPs were excited by irradiating the dye layer with a blue laser. We successfully collected radiation from SPPs by converting them into far-field radiation using a prism coupling technique.

Single-Walled Carbon Nanotubes (SWCNTs) have been shown to be a promising candidate for flexible electronics, especially logic circuits. However, very little study on SWCNT based analog circuit elements, such as amplifiers and comparators, on flexible substrates has been reported. For practical applications, fully functional flexible electronic devices must have an analog input circuitry to achieve appropriate functionalities. In this work, we demonstrate a resistive SWCNT gas sensor integrated with an amplifier circuit on flexible substrate to detect and amplify the sensing signals.

Quantum dot laser diodes are expected to replace conventional semiconductor laser diodes in new high-speed information and communication devices. We successfully fabricated disk-shaped quantum dots using a bio-template and neutral beam etching. Our original top-down process achieved defect-less and a high density of dots from etching process compared with conventional plasma processes. Therefore, we attempted to detect emission from the quantum energy levels in the quantum nanodisks (QNDs) for as-etched sample without post-fabrication process. We prepared 4-stacked GaAs/AlGaAs layer QNDs samples after etching (as-etched) and after regrowth. QNDs samples were investigated by photoluminescence (PL) measurements. Results showed some broad peaks appearing between the bandgaps of GaAs and AlGaAs. We compared our experimental results with energies theoretically estimated energies using a nextnano 3D simulator with QND different diameters. For both type of samples, we found that QND diameters increased from top to bottom. From PL measurement, we observed emission from QNDs for as-etched samples fabricated using our own original top-down process.

Molecular dynamics simulations have been performed to clarify the scattering phenomena of oxygen molecules on ionomer thin films, which affect the transport resistance of oxygen in catalyst layers in polymer electrolyte fuel cells. We have evaluated the probability density functions of the translational energy and scattering angle of scattered molecules, and the residence time of oxygen molecules on the ionomer surface. It was found that the energy distributions of scattered oxygen molecules depend on the incident energy and differ from that of thermally equilibrated molecules. On the other hand, the angular distributions are independent of the incident energy, and well reproduced by the diffusive scattering model. These results indicate that oxygen molecules do not accommodate completely with ionomer surface during the collision. We also evaluated the trapping dynamics of oxygen molecules on the ionomer surface in the trajectory calculations. Increasing the normal component of the incident energy results in the longer residence time on the ionomer surface.

Silicon is a promising anode material for lithium-ion battery application due to its high specific capacity. Unfortunately, silicon undergoes a volume expansion of 300~400% full lithiation and suffers from severe capacity fade, which limit its successful application in commercial cells. In this study, we used in situ acoustic emission and laser microscope observation method for detecting the volume change in silicon negative electrodes. It was shown that the long-term performance of the silicon negative electrode was dictated by its spallation during the discharge steps, while only the first lithiation caused its delamination and spoliation in the charge step. This strongly indicates that the energy of emission, and hence the amount of damage, is related to capacity loss. This study demonstrate that AE is a powerful tool to survey the real-time mechanical damage and electrochemical degradation in the electrode.

In this paper, thin film diamond resonators on Si wafer for high sensitivity force sensing have been developed. Patterned diamond structures have been formed on Ir/YSZ/Si substrate. The completed diamond resonator of cantilever shows a resonance frequency of 51.0 kHz with a quality factor of 14911. The both clamped resonator shows the force sensitivity of 3.36×10-13 N/Hz0.5 at 229.3 kHz with 23500 of Q factor. While the crystallites and surface roughness are required to be improved, the patterned diamond resonator can be used as a high sensitive physicochemical sensing tool.
