Ultra-high voltage electron microscopy is useful for research utilizing high-penetration thickness of electron beam, in situ observation, or irradiation effects by the particle characteristics of electrons. In this review, the importance of non-equilibrium materials science research by a combination with irradiation e…
Reaction of the tungsto‐antimonate [Sb8W36O132]24– polyoxometalate with late trivalent lanthanide cations (from Gd to Lu) gives rise to the formation of eight isostructural molecular compounds [{Sb3(µ3‐O)2Ln(H2O)Ln(H2O)2(SbW10O37)(SbW8O31)}2]22– (Ln = GdIII (1), TbIII (2), DyIII (3), HoIII (4), ErIII (5), TmIII (6), Y…
Abstract. Solid oxide fuel cell (SOFC) is an electrochemical conversion device that undergoes a thermal cycling at various operating temperature where lead to the degradation of its mechanical properties. Electrolyte among the main component in SOFC plays a crucial part in defined the overall performance which facing…
Objective: Indonesian metal casting industry is a labor-oriented industry which involves thermal application in the workplace. Thus, it is essential to protect the workers for any risks during their activity. Leather gloves, as personal protective equipment, need to be manufactured that can prevent the workers from bu…
The molecular recognition capability of naturally occurring biomolecules is generally expressed against biomolecules in the biological milieu. Recently, it was demonstrated that the specific interactions of biomolecules such as short peptides were applicable to artificial materials. We have developed peptides with spe…
Abstract We investigate the applicability of the Gibbs free energy landscape to the definition and understanding of transient negative capacitance in a ferroelectric capacitor. We find that the Gibbs free energy cannot define the transient negative capacitance. In order to define the negative capacitance, we suggest r…
Abstract In this letter, we propose, fabricate, and characterize both an enhancement mode (E-mode) and a depletion mode (D-mode) MOSFET on a standard LED epitaxial wafer based on silicon substrate for the first time. The devices are fabricated on the n-GaN layer or undoped-GaN layer of the LED epitaxial wafer by semic…
The purpose of this research was synthesis and electron beam modification of novel ester elastomers consisting of sugar alcohol–succinic acid block and butylene glycol–succinic acid block. Four different alditols were used in the synthesis—sorbitol, erythritol, xylitol, and glycerol. The materials were irradiated with…
This chapter discusses the molecular origins of toughness in polymeric systems. The mechanical properties of materials are of great importance in engineering applications. When a mechanical force is applied to a specimen, the deformation of the specimen is described in terms of its stress—strain behavior. The descript…
Crystallographic structural analysis is an essential method for the determination of protein structure. However, crystallization of a protein of interest is the most difficult process in the analysis. The process is often hampered during the sample preparation, including expression and purification. Even after a sampl…
The major part of solid-state transformations modeling has concentrated on transformations taking place from a homogeneous matrix. Nonetheless, there are situations in which one finds an inhomogeneous matrix. An example is the recrystallization of metals subjected to an inhomogeneous deformation. If the recrystallizat…
A Cu(I) coordination polymer, {[Cu4Br(ttpe)3]Br2·(OH)}n (1), was prepared and characterized by single crystal X-ray diffraction analysis, EA, IR, PXRD, luminescence, optical band gaps and VB XPS spectra (ttpe = 1,1,2,2-tetrakis[4-(1H-1,2,4-triazol-1-yl)phenyl]ethylene). 1 presents a two-fold interpenetrating (4,12)-co…
Two new homo-dinuclear zinc(II) complexes, bis(µ-pyrazolato-) bis[(formato)(pyrazole)zinc(II)], [{Zn(OCHO)(pzH)}2(µ-N2H3C3)2] (1) and bis(µ-3,5-dimethylpyrazolato)bis[(formato)(-3,5-dimethylpyrazole) zinc(II)], [{Zn(dmpzH)(OCHO)}2(µ-N2H7C5)2] (2), were synthesized through the reactions of zinc(II) formate dihydrate, Z…
In Taipei, over 45% of the energy used in buildings is for air-conditioning systems. In particular, multiple chiller systems consume about 70% of the energy in an air-conditioning system. Consequently, optimal chiller loading (OCL) or energy saving of a building is a vital issue. In this paper, we report a newly devel…
Abstract Due to its huge surface-to-volume ratio, graphene has become one of the most popular materials for sensors. However, H 2 O molecules in atmospheric environments can cause the instability of graphene devices, which greatly limits the practical applications of graphene devices. The charge transfer between graph…
Polarized neutron diffraction is used to study in depth the magnetic properties of the heterometallic compound [NH2(CH3)2][FeIIIFeII(HCOO)6] and give insight into its magnetic behaviour, addressing open questions that will contribute to a better understanding of this attention-grabbing material and other related ones.…
Abstract This study focuses on the evolution of a new biodegradable material sourced from agro-waste, and how it plays a vital role in replacing nonbiodegradable material. In the present work, new fibers were extracted from the pseudo stem of the Nendran variety of the banana plant. Initially, anatomical studies were…
Metastable α"-Fe16N2is considered to be a good candidate as a semi-hard magnetic material with high saturation magnetization. To obtain a higher coercivity Hc, it is necessary to improve the magnetocrystalline anisotropy of α"-Fe16N2. For this purpose, many theoretical calculations based on substitution of Fe with oth…
We reanalyze the results from a set of terminal ballistics tests in which large limestone targets were impacted by similarly shaped rigid projectiles having different sizes. Our first goal is to show that the data in terms of penetration depths as a function of impact velocity can be accounted for by a model in which…
An instrumented 1:70 scale model underground tunnel, located below a free water body, was subjected to explosions in centrifuge model tests. Utilising centrifuge scaling relations, each test at 70g modelled the effects of an explosion due to approximately 0.9 t of trinitrotoluene equivalent. The explosives were locate…
