Modern technology has advanced swiftly, and thus, people have higher and higher demands for functional textiles. In order to have textiles with electromagnetic shielding effectiveness (EMSE) and far infrared emissivity, in this research, we fabricated three types of bamboo charcoal/metal (BC/M) complex yarns with meta…
A ray transfer matrix is used to calculate the propagation of aberrated wavefronts across a homogeneous refractive index. The wavefront is represented by local surface normals, i.e., by a ray bundle, and the propagation is accomplished by transferring those rays across the space. Wavefront shape is generated from the…
Mesoporous fibers have attracted great interest because of their potential applications in various fields such as catalysts, sensors and electrodes. Various mesoporous fibers with different compositions such as metals, alloys, metal oxides, and carbons have been prepared by the use of both hard-templates and soft-temp…
A novel approach, which can delicately form a desirable film profile for deposited gate oxide, channel, and source/drain contacts of oxide-based thin-film transistors (TFTs) is proposed. To demonstrate the film-profile engineering concept used in this approach, a simple one-mask process was developed for fabricating Z…
Porous tantalum has been used as an orthopedic implant for bone defects as it has a good corrosion resistance and fatigue behaviour properties. However, there are some reports on the rejection of porous Ta after the implantation. Those clinical cases refer to the less bioactivity of metallic-based materials. This stud…
Abstract In our work, large diameter ZnTe single crystals were grown by various melt growth methods. By a liquid encapsulated vertical gradient freezing method, crystals with large grains and low dislocation density were obtained. By a liquid encapsulated Kyropoulos method, 80 mm diameter crystals were successfully gr…
The three-dimensional (3D) spatial structure of an iron oxide containing alkyd paint specimen has been investigated by serial block-face scanning electron microscopy (SBFSEM). The resultant images of the 3D structure clearly present the spatial distribution of the iron oxide pigment particles in the coating film and r…
Nonthermal atmospheric pressure plasma (NTP) has been extensively studied for biological and medical applications in recent years. Chemically active species are generated and injected into aqueous media subjected to plasma exposure. They play an important role in the activation and/or inactivation of biomolecules, suc…
Abstract Nanocast ordered mesoporous carbons are attractive as sorbents because of their extremely high surface areas and large pore volumes. This paper compares Pu uptake, added as Pu(VI), to both untreated and chemically oxidized CMK-(carbon molecular sieves from KAIST) type mesoporous carbon with that to a commerci…
Microdome structures are analyzed as surface topology to reduce surface reflection over a broad spectral range and wide light incidence angle for concentrator photovoltaics application. Three dimensional finite difference time domain method was used to accurately calculate the surface reflection and transmission for s…
Dielectric properties of heat treated in air and in vacuum Na0.5Bi0.5TiO3 single crystals are studied. It is shown, that above 350°C ɛ and tanδ exhibit sufficient temperature hysteresis and strongly depend on AC field frequency and heat treatment conditions. Low frequency dielectric dispersion around 400°C and tempera…
In this study, bending fatigue behavior of Japanese cedar and Selangan batu was examined.A nonreversible triangular waveform with loading frequencies of 0.5 and 5 Hz was used as load.Applied loads were about 110-70% of the static strength.The fatigue life of Japanese cedar was found to be longer at 5 Hz, especially at…

We have measured physicochemical properties of five alkyltrimethylammonium cation-based room-temperature ionic liquids and compared them with those obtained from computational methods. We have found that static properties (density and refractive index) and transport properties (ionic conductivity, self-diffusion coeff…
This work aims to synthesize room-temperature ionic liquids (RTILs) by combining cations (ie olefins and alkyl-based imidozalium) and anions (phosphate and chloride). The synthesized RTILs exhibited considerable solubility for pulp at temperatures ranging from 35 to 100°C compared with the typical ILs of 1-butyl-3-met…
A simple yet robust approach was exploited to fabricate large-scaled patterned polymer brushes by combining controlled evaporative self-assembly (CESA) in a confined geometry and self-initiated photografting and photopolymerization (SIPGP). Our method was carried out without any sophisticated instruments, free of lith…
AIMS AND BACKGROUND: Aberrant expression of the trefoil factor family (TFF) has been recognized to be involved in the development and/or progression of various solid tumors. Increased trefoil factor 1 (TFF1) expression is found associated with tumor progression in some tumors, and TFF1 missense mutations have been det…
In this paper, we discuss a range-separation density-fitting method for obtaining the electronic band structure. The formalism is based on Gaussian orbital basis functions. The Hartree term and the nuclear attractive term are divided into long- and short-range contributions by using the error and complementary error f…
Abstract Reactions of silver(I) nitrate with 1,3‐imidazolidine‐2‐thiones (LI‐NH, LI‐NMe), 1,3‐imidazoline‐2‐thiones (LII‐NH, LII‐NMe), and that of silver(I) acetate with thiazolidine‐2‐thione (LIII‐NH), or benz‐imidazoline‐2‐thione (LIV‐NH) and triphenylphosphine (PPh3) as co‐ligand (1:2:2 molar ratios) in acetonitril…
We investigate whether a novel and inexpensive etching method, H3PO4 + NaF, on titanium could obtain both a lower hydrogen content and superior calcium phosphate deposition performance, while achieving similar surface roughness in comparison with the traditional etching method. Pure titanium samples were treated with…
