Silicon direct bonding offers flexibility in the design and development of Si optics by allowing manufacturers to combine subcomponents with a potentially lossless and mechanically stable interface. The bonding process presents challenges in meeting the requirements for optical performance because air gaps at the Si i…
The key material of high-speed train gearbox shells is high-strength aluminum alloy. Material damage is inevitable in the process of servicing. It is of great importance to study material damage for in-service gearboxes of high-speed train. Structural health monitoring methods have been widely used to study material d…
More than 30% enhancement in photocurrent is achieved by separating light confinement and absorption sites within the solar cell.
This chapter covers first the precipitation and coarsening processes in Fe-Ni-Al alloys aged artificially at high temperatures, as well as their effect on the mechanical properties. These results show the precipitation evolution, morphology of precipitates, coarsening kinetics and mechanical properties such as hardnes…
The storage of hydrogen is considered as the bottleneck in the implementation of portable fuel cell power generating systems. The necessary experimental studies to discover and develop appropriate storage materials are always time-limited. We discuss herein the approach of an uncomplicated and accessible computational…
The electronic absorption and reflectance spectra of Pr(III) ions in molten alkali metal fluorides have been studied. For electronic transitions in the series LiF → NaF → KF → CsF, a long-wavelength shift is observed (nephelauxetic effect). The intensity of the hypersensitive transition 3 H 4 → 3 P 2 (ΔJ = 2) depends…
Utilization of (2)H, (13)C, and (15)N isotopically labeled proteins and peptides is now routine in biomolecular NMR investigations. The widespread availability of inexpensive, uniformly (13) C enriched glucose now makes it possible to isolate uniformly (13)C labeled natural products from microbial fermentation. We now…
Oksida grafit (GO) telah berhasil disintesis menggunakan metode Hummers dari serbuk grafit dengan pelarut asam sulfat (H2SO4), natrium nitrat (NaNO3), kalium permanganat (KMnO4), dan hidrogen peroksida (H2O2). Hasil sintesis berupa pasta dicuci dengan asam klorida (HCl) dan akuades berulang-ulang untuk mendapatkan GO…
The special structure of deformed TiO2aggregate composed of connected nanoparticles was synthesized by the sol-gel method and hydrothermal processes with triblock copolymer as a template. The preliminary experiment of dye-sensitized solar cells (DSSCs) with deformed TiO2aggregate as a photoanode was investigated. Fiel…
Adverse natural conditions will, generally, induce gemmulation in freshwater sponges. Because of this environmental dependence, gemmoscleres are given exceptional value in taxonomic, ecological and paleoenvironmental studies. Other spicules categories such as microscleres and beta megascleres have received little atte…
2-Acylated 2,3,1-benzodiazaborines can display unusual structures and reactivities. The crystal structure analysis of the boron heterocycle obtained by condensing 2-formylphenylboronic acid and picolinohydrazide reveals it to be an N→B-chelated zwitterionic tetracycle (systematic name: 1-hydroxy-11-oxo-9,10,17λ(5)-tri…
A new cobalt(II)-based metal-containing ionic liquid (MCIL), 1, has been prepared that reversibly and selectively absorbs O 2 with an associated colorimetric change. This MCIL was impregnated into a porous PTFE polymer support, and the resulting supported membranes show higher O 2 sorption over N 2 with increasing loa…
Complex light trapping structures make it challenging to simulate the optical properties of solar cells accurately. In this paper, a framework is proposed where matrices are used to describe the transition of the angular distribution of the light when it is reflected, transmitted or absorbed. The matrices can be compu…
Metamaterials researchers seek to build on past successes, such as cloaking, by adding control features to artificial electromagnetic media. This study presents a scheme whereby an active metamaterial featuring conventional structures plus a magnetically hard alloy can be ``written'' (much like the memory elements of…

Abstract The dependence of pedestal structure on collisionality at fixed beta has been investigated in JT-60U. In the ITER-relevant low collisionality regime, the pedestal width does not change with edge collisionality. In the high collisionality regime, the pedestal width broadens with increased edge collisionality.…
Blue poly(styrene‐co‐methacrylic acid) nanospheres were prepared by dyeing polymer dispersions with CI Disperse Blue 56. The coloured nanospheres had a clear shell with a thickness of 32.5 nm. The average diameter of the nanospheres increased from 288 to 353 nm, and the glass transition temperature was raised from 109…
To obtain insight into pH change-driven molecular dynamics, we studied the higher order structure changes of protein G'e at the molecular and amino acid residue levels in solution by using nanoESI- and IM-mass spectrometry, CD spectroscopy, and protein chemical modification reactions (protein footprinting). We found a…
Benzobis(thiadiazole) derivatives showed a large diffusion coefficient between the molecules located in the co-planar and the standard π–π stacking directions.
New C -functionalized dioxocyclam and cyclam derivatives with 1,2,3-triazoles attached to carbon atoms within the skeleton were designed as valuable bifunctional chelators for molecular imaging.
