Complex functional perovskite oxides find use in a wide range of applications as dielectric, electronic, photocatalytic, optical, and ion-conducting materials. The ability to synthesize perovskites in hierarchical structures can allow for new properties or phenomena not observable in bulk morphologies. Herein we repor…
NASA Astronaut Dr. Pettit carried out a thermocapillary flow experiment onboard the International Space Station in 2003. In this experiment a thin water film containing milk powder was formed in a stainless-steel wire ring. Heating a section of the ring by a soldering iron induced in the water film a thermocapillary f…
Abstract The thermoreactive deposition and diffusion process is a heat-treatment-based method to form coatings with compacted layers of carbides, nitrides, or carbonitrides, onto some carbon/nitrogen-containing materials, including steels. The amount of active carbide forming elements/nitride forming elements, coating…

Protein kinase A (PKA) is the archetypical phosphokinase, sharing a catalytic core with the entire protein kinase superfamily. In eukaryotes, the ubiquitous location of PKA makes it one of the most important cellular signaling molecules, involved in a myriad of events. The catalytic subunit of PKA (PKA-C) is one of th…
Developed a new method of electrolytic-plasma nitriding, which enable to carry out surface modification of high-speed steels and provide the high kinetic energy efficiency of diffusion saturation process. . Implementation of electrolytic-plasma nitriding of high-speed steel R6M5 in the optimal mode was determined, whi…
The change in threshold voltage ( V th ) in AlGaN/GaN high-electron-mobility transistors (HEMTs) on Si occurs during off-state bias stress. Raman spectroscopy shows that the GaN strain/stress changes with the increase in buffer and i-GaN thicknesses. Our results revealed that there is a strong correlation between the…
The trend to increased energy efficiency and profitable capital expenditure leads to the operation of drive systems at or near their rated values and to increased running time. Thus, down time due to machine breakdown (e.g. in a traction drive) leads to high economic losses for the operator. Furthermore, the breakdown…
The actively water-cooled plasma facing components (PFCs) of the Wendelstein 7-X stellarator consisting of the first wall protection and the divertor systems have a total surface area of about 265m2. The complex 3D geometry of the plasma and plasma vessel with 244 vessel ports dedicated to diagnostics, heating systems…
We have investigated experimentally the process of a droplet impact on a regular micro-grooved surface. The target surfaces are patterned such that micro-scale spokes radiate from the center, concentric circles, and parallel lines on the polishing copper plate, using Quasi-LIGA molding technology. The dynamic behavior…
Abstract Saprolegnia is an important fish fungal pathogen that often results in significant economic losses to freshwater aquaculture. To find effective drugs to control saprolegniasis, 30 fungicidal chemicals used in agriculture were screened, in which kresoxim‐methyl and azoxystrobin, with minimum inhibitory concent…

Photodynamic therapy (PDT), utilizing photosensitizers and light, has received considerable interests for its potential to treat microbial infections. The advantages of antimicrobial PDT include a broad spectrum of action, efficient killing against wild-type as well as drug-resistant pathogens. Therefore, antimicrobia…
Atomic layer deposition(ALD) is a promising deposition method and has been studied and used in many different areas, such as displays, semiconductors, batteries, and solar cells. This method, which is based on a self-limiting growth mechanism, facilitates precise control of film thickness at an atomic level and enable…
A 20 barrel solid hydrogen pellet injector, which is able to inject 20 cylindrical pellets with a diameter and length of between 3.0 and 3.8 mm at the velocity of 1200 m/s, has been developed for the purpose of direct core fueling in LHD (Large Helical Device). The in situ pipe gun concept with the use of compact cryo…
The objective of this article is to systematically present the emerging understanding that 3D porous scaffolds serve not only as structural templates for tissue fabrication but also provide complex signaling cues to cells and facilitate oxygen and therapeutic agent delivery. Strategies in the field of tissue engineeri…
Although many proteins are recognized to undergo folding via an intermediate, the microscopic nature of folding intermediates is less understood. In this study, ¹⁹F NMR and near-UV circular dichroism (CD) are used to characterize a transition to a thermal folding intermediate of calmodulin, a water-soluble protein, wh…
We present the results of the pressure dependence of the superconductivity of the inorganic electride 12CaO·7Al2O3:e− (C12A7:e−) single crystal through the ac-susceptibility measurement under high pressure. C12A7:e− has the cage structure and the density of states derived from the cages may play an important role in t…
Switchable surfactants, particularly those triggered by CO2 used for switchable foam control, are relatively less documented. In this article, the foaming performance of 2-alkyl-1-hydroxyethylimidazolinium bicarbonate cationic surfactants (HEAIBs) was investigated for the first time. The foaming properties of these su…
BaCo 2 X 2 O 7 (X = P, As) compounds are formed of chains of Co 2+ O 8 dimers. In a first approximation, the structural chains appear strongly isolated, which gives a pronounced one-dimensiona (1D) magnetic character to the systems. GGA+U calculations show ferromagnetic (FM) exchanges inside the dimers and predominant…
