Using angle-resolved photoemission spectroscopy, we present the electronic structure of the metallic ground state of ${\text{La}}_{2\ensuremath{-}2x}{\text{Sr}}_{1+2x}{\text{Mn}}_{2}{\text{O}}_{7}$ $(x\ensuremath{\approx}0.59)$ and interpret the results in terms of first-principles band-structure computations, of whic…
Dunalia spinosa, a plant used in folk medicine for toothaches, breathing problems and cleansing wounds, was found active as antimicrobial and antioxidant. A new (E)-aurone rutinoside (dunaurone) has been isolated from the aerial parts of the plant, and its structure was determined by spectroscopic means. Lupeol, beta-…
The interlaminar shear property of composites remains a serious concern in application. In this article, five different multiwalled carbon nanotubes (MWCNTs) are tried to improve the interlaminar shear property of composites, including two MWCNTs (MWCNTs-A and MWCNTs-B) different with diameters and lengths, an orienta…
The effect of the grain size and transverse film size in nano-and micrometer ranges on the parameters of martensitic transitions in shape memory alloys is theoretically considered in the framework of the theory of diffuse martensitic transitions. A quantitative analysis of the size effects is performed including not o…
Twins in the B19 (2H) martensite in Ti–Pt shape memory alloy have been investigated by transmission electron microscopy. There are three twinning modes evident, i.e. {111} 2H Type I, <121> 2H Type II and {101} 2H compound twins. In addition to the 2H martensite, various long period stacking structures are observ…
Abstract In this work, the main attention was focused on the synthesis of stimuli-responsive magnetic nanoparticles (SR-MNPs) and the influence of glutathione concentration on its cleavage efficiency. Magnetic nanoparticles (MNPs) were first modified with activated pyridyldithio. Then, MNPs modified with activated pyr…
Silk has been used commercially as biomedical sutures for decades. Recently silk fibroin, especially from Bombyx mori silkworm, has been explored for many tissue engineering applications such as bone and cartilage due to its impressive biological compatibility and mechanical properties. In Thailand, Thai native silkwo…
In this paper, we demonstrate the effect of electrodynamic focusing through a gold-coated PDMS shadow mask on the selective deposition of electrospun nanofibers. Under a suitable applied voltage, the PDMS mask repels the fibers from its surface while simultaneously forcing them into micron-sized holes and onto a colle…
Abstract A novel pyroelectric ferrimagnet, [{MnII(pyrazine)(H2O)2}{MnII(H2O)2}{NbIV(CN)8}]·4H2O, is synthesized. The crystal consists of an NbIV–CN–MnII linked three-dimensional network, which has an electric polarization along the b axis. This compound exhibits ferrimagnetism with a Curie temperature of 48 K due to t…
With boron substituting for carbon in cast iron composition and eutectic borides substituting for eutectic carbides in microstructure as the hard wear resistant phase, a new kind of wear resistant white cast iron has been developed. The microstructure and mechanical properties of this new white cast iron both in the a…
Dielectric response measurements, in both time and frequency domains, can generate valuable information about the condition of cables affected by water tree degradation. However, the interpretation of how these dielectric response measurements relate to water tree density and length is a difficult task. This difficult…
Due to the widespread use of polymeric insulating materials in radiation environments, there is an increasing demand to evaluate the radiation effects on the surface dielectric characteristics of polymeric insulating materials. This paper presents a recurrence plot approach to analyze the surface discharge of gamma-ra…
The crystallization mechanism of anhydrate/hydrate has to be understood in order to control the hydration state of an active pharmaceutical ingredient. In the present work, the formation of the anhydrous (CBZA) and dihydrate (CBZH) form of carbamazepine (CBZ) in ethanol−water solutions was studied by simultaneous moni…
Experimental data are presented for an evaluation of the solubility of tantalum in the ternary system CaCO 3 – Ca(OH) 2 – NaTaO 3 (or calcite – portlandite – sodium tantalate) over the temperature range 550 to 900°C at 0.1 GPa pressure. Near-liquidus phase relationships are given for the pseudobinary join ([CaCO 3 ] 4…
Several lumped element-based epsilon-negative (ENG), mu-negative (MNG), and double-negative (DNG) metamaterial designs have been developed for operation at 400 MHz in the UHF frequency band. The use of lumped elements enabled the creation of highly sub-wavelength unit cells whose overall size was λ0/d∼75 at 400 MHz. T…
Molecular dynamics simulations and selected experiments have been carried out to study the growth of Cu films on (010) bcc Ta and the deposition of CuxTa1−x alloy films on (111) fcc Cu. They indicate that fcc Cu films with a (111) texture are always formed when Cu is deposited on Ta surfaces. These films are polycryst…
Abstract The uniform and intergranular corrosion behavior of two kinds of nickel‐free and manganese alloyed high nitrogen stainless steels (HNSSs) were investigated. A type of 316L stainless steel (316L SS) was also included for comparison purpose. Both solution annealed (SA) and sensitization treated (ST) steels were…
Ternary Zn1−xCoxO crystalline films with different compositions were grown by electrodeposition. The Co content in the final compound is linked to the initial Co/Zn ratio in the starting solution. X-ray diffraction reveals a wurtzite structure for the Zn1−xCoxO films. Transmittance spectra show two effects proportiona…
Currently, environmental problems such as global warming are important issues, and SF6has been identified as a greenhouse gas with a long atmospheric lifetime. Therefore, in the long term, it is preferable to reduce the amount of SF6used as an insulating gas. It is thus important to discuss the possibility of using mo…
Abstract Cd(OH) 2 nanobelts have been synthesized in high yield by a convenient polyol method for the first time. XRD, XPS, FESEM, and TEM were used to characterize the product, which revealed that the product consisted of belt-like crystals about 40 nm in thickness and length up to several hundreds of micrometers. St…
