In recent years, activatable Quantum Dots (AQdots) are gaining popularity in a number of chemical and biological sensing applications. A basic design of AQdot probes involves a suitable quencher which is capable of altering optical properties of the Qdots. In our previous studies we have shown that CdS:Mn/ZnS fluoresc…
We demonstrate a nanostructured broadband absorber in visible range. Two kinds of structures with different absorption ranges are designed and fabricated using nanoimprint lithography. Experiments show a flat absorption spectra with an average absorption of 85% from 400 nm to 700 nm. The proposed structures could be u…
Abstract A novel X‐type polyester (5) containing 4‐(2′,2′‐dicyanovinyl)‐6‐nitroresorcinoxy groups as nonlinear optical (NLO) chromophores, which constitute parts of the polymer backbone, was prepared and characterized. Polyester 5 is soluble in common organic solvents such as N,N‐dimethylformamide and acetone. Polyest…
In the present paper, ultra fast cooling (UFC) technology was applied in the cooling process to treat medium carbon steels after hot strip rolling, and the finish rolling temperature and UFC stop temperature are controlled as the important parameters. The effects of cooling path on the microstructure and hole-expansio…

Grain refinement in metallic materials down to submicro and nano scale results in improvement of mechanical properties. However, increase in strength under static load is not always accompanied by improved fatigue behaviour. In the current studies microstructure and mechanical properties of the submicrocrystalline RS4…
Surface enhanced Raman scattering (SERS) has been used to detect biological molecules at a low concentration. We developed a rapid Raman imaging system, which can image dynamic activity of SERS agents, such as gold nanoparticles, in a living cell and the temporal behaviors of SERS spectra. Combination of slit scanning…
Ein supramolekularer Klettverschluss mit starker und reversibler Adhäsion unter Wasser wurde mit einem synthetischen, extrem hochaffinen Wirt-Gast-Paar aus Cucurbit[7]uril (CB[7]) und Aminomethylferrocen (Fc) erhalten. In der Zuschrift auf S. 3222 ff. zeigen K. Kim et al., dass sich die CB[7]-Schlaufen und die Fc-Hake…
Different types of carbon nanotube + graphene quantum dot composites were investigated. Stable configuration of carbon nanotube + graphene quantum dot composites with the van der Waals and the chemical interactions were established. It was shown that a peapod + graphene quantum dot (GQD) composite is a stable configur…
The elimination of severe power excursion during core disruptive accidents is a key issue for the enhanced safety of sodium-cooled fast reactors. In order to prevent the formation of a large-scale molten fuel pool within a reactor core, which is one of the factors leading to the severe power excursion, the Japan Atomi…
Introduction: Recent research has focused on developing new biomaterials for delivery of imaging agents and drugs. In our study, we report a new biocompatible and biodegradable polymer, termed poly(glycerol-co-malic-dodecanoate) (PGMD), which was then used for synthesis of nanoparticles (NPs) and loading of NIR dyes.…
A series of rubidium aryloxides, [Rb(OAr)(solv) n ] x , was synthesized from the reaction of Rbo with a select set of 2-alkyl phenols [alkyl = methyl (H-oMP), iso-propyl (H-oPP), and tert-butyl (H-oBP)] and 2,6-di-alkyl phenols [alkyl = methyl (H-DMP), iso-propyl (H-DIP), and tert-butyl (H-DBP)]. The products were ide…
We report a novel plasmonic tuning technique which allows colorimetric, naked-eye detection of protein-protein binding at extreme sensitivities. Utilizing an engineered approach to molecularly-driven plasmonic-coupling, we construct three-part plasmonic “bowtie” structures within protein nanoarrays using single biomol…
In this work, we demonstrate a monolithic approach to fabricate free-standing LiNbO3 photonic crystal (PhC) slabs. Ion implantation is first applied to form a buried lattice-damage layer at a specified depth in bulk LiNbO3. Photonic crystal slabs are then made with FIB milling followed by wet etching. A high etching r…

Rb 1.75 [Pt(CN) 4 ] · 1.25H 2 O crystallizes monoclinic in the space group P 2 1 / c [ a = 1171.4(2) pm, b = 3315.3(6) pm, c = 1054.4(2) pm, β = 114.253(2)°, V = 3733.2(11) · 10 6 pm 3 , Z = 16, N total = 3156…
Abstract Based on compressive tests, static on 810 material test system (MTS) and dynamic on the first compressive loading in split Hopkinson pressure bar (SHPB) tests at different strain rates and temperatures for Lanthanum (La) cylinder specimens, this study determined Johnson-Cook (J-C) type compressive constitutiv…
Interleaflet cavitation in lipid bilayer membranes, or, shortly, intramembrane cavitation (IMC), is the formation of gas bubbles between the two leaflets of the membrane. The present paper focuses on the thermodynamics of IMC, namely, on the minimum work required to form an intramembrane cavity. The minimum work can b…
An artificial nacre based on graphene oxide sheets is presented by Q. F. Cheng, M. Z. Li, Z. Y. Tang et al. in their Communication on page 3750 ff. This ultratough material shows excellent mechanical properties and a hierarchical microstructure. The bioinspired strategy involves a new concept for fabricating artificia…
Ultrasonic time‐of‐flight ( TOF ) is investigated as a predictor of density variation across reaction‐sintered silicon carbide ( S i C ) ceramics. The importance of this research is heightened by the fact that the reaction‐sintered S i C ceramic tiles being investigated are manufactured using the reaction sintering pr…
Currently, the focused ion beam milling (FIB) technique is a commonly used approach to fabricate nanostructures because of its unique advantages of one-step fabrication, nanoscale resolution, and no material selectivity, etc. However, the FIB technique also has its own disadvantages. Regarding the process of fabricati…
