We study the dynamics of individual polystyrene ellipsoids of different aspect ratios trapped at the air-water interface. Using particle tracking and in situ vertical scanning interferometry techniques we are able to measure translational drags and the protrusion in air of the ellipsoids. We report that translational…
The ability to control propagation of electromagnetic guided modes lies at the heart of integrated nanophotonics. Surface plasmon‐polaritons are a class of guided modes which can be employed in integrated optical systems. Here, we present a theoretical design of a coherent surface plasmon absorber which can perfectly…
Composition spread alloy films (CSAFs) are commonly used as libraries for high-throughput screening of composition-property relationships in multicomponent materials science. Because lateral gradients afford two degrees of freedom, an n-component CSAF can, in principle, contain any composition range falling on a conti…
Kidneys are involved in essential complex procedures that maintain the body in equilibrium and preservetheinterior environment necessary for life Nephritis and nephrosis were ranked among the leading causes of death in all ages in the last global burden of disease assessment of the World Health Organization WHO Regard…
A jacketed stirred-cell reactor, operated semicontinuously, was used to assess the kinetics of fast ozonation reactions by reactive absorption. The method was applied to the direct ozone reaction with resorcinol. A high resorcinol concentration was used to reach a steady state and to neglect byproduct accumulation. Th…
In this letter we report the synthesis and characterization of two new heptagon-embedded nonplanar π-conjugated molecules, which can be regarded as synthetic precursors of hepta- peri -heptabenzo-[7]circulene, an interesting but unknown polycyclic arene with negative curvature.
In this paper, we investigate the counterintuitive dispersion effect associated with the poles and zeros of reflection and transmission functions in an Otto configuration when a surface plasmon resonance is excited. We show that the zeros and/or poles in the reflection and transmission functions may move into the uppe…
The equilibrium phase diagrams of NaCl–ZnCl 2 –H 2 O system at 260.35 and 250.15 K were studied by method of isothermal solution saturation, wet residues, and thermogravimetric analysis. Water content in precipitate at these temperatures for hydrate 2NaCl·ZnCl 2 · n H 2 O was determined, n = 3. Densities of ternary Na…
Micro arc oxidation (MAO) coatings doped with graphene oxide (GO) were prepared on the 6061 Al alloy substrates in the electrolyte composed of an aqueous solution of sodium silicate (Na 2 SiO 3 ·9H 2 O, 20 g L −1 ) and 100 mg L −1 GO. The microstructure, mechanical property and tribological behaviour of the MAO + GO c…
In this paper, we describe the reasoning that leads us to focus on the so-called curing process where a solid poly(ɑ-methylstyrene) (PAMS) shell is formed from the initial solution phase. We demonstrate the existence of a percolation zone at about 55 wt% PAMS, beyond which the roundness of the shell can be expected to…
To identify the optimal deformation parameters for 316LN austenitic stainless steel, it is necessary to study the macroscopic deformation and the microstructural evolution behavior simultaneously in order to ascertain the relationship between the two. Isothermal uniaxial compression tests of 316LN were conducted over…
The rational design and controlled synthesis of a smart device with flexibly tailored response ability is all along desirable for bioapplication but long remains a considerable challenge. Here, a pH-stimulated valve system with a visualized "on-off" mode is constructed through a dual-shell fluorescence resonance energ…

The crystallization properties of polymers strongly influence their mechanical and chemical performance. In this paper, the influence of silicon carbide (SiC) and vapour growth carbon fiber (VGCF) particles on polyphenylene sulphide (PPS) crystallization and composite properties was studied using differential scanning…
The roles of electrostatic interactions in protein folding stability have been a matter of debate, largely due to the complexity in the theoretical treatment of these interactions. We have developed computational methods for calculating electrostatic effects on protein folding stability. To rigorously test and further…
Sensitive detection of a specific deoxyribo nucleic acid (DNA) sequence is important for biomedical applications. In this report, a two-step amplification strategy is developed based on magnetic nanoparticles (MNPs) to achieve ultrasensitive DNA fluorescence detection. The first level amplification is obtained from mu…
Energy dispersive X-ray spectroscopy within the scanning transmission electron microscope (STEM) provides accurate elemental analysis with high spatial resolution, and is even capable of providing atomically resolved elemental maps. In this technique, a highly focused electron beam is incident upon a thin sample and t…
This work is focused on montmorillonite (MMT)-based “support-activators” (S-As) for the metallocene-catalyzed propylene polymerization. This catalyst was previously industrialized; however, for further technological advances, the activation mechanism is investigated. The chemical and morphological requirements of the…
The solid state and solution properties of tris(2-thienyl)methylsilane, I, tetrakis(2-thienyl)silane, III, and their positional isomers bearing 3-thienyl groups ( II and IV ) were investigated and compared. The tris(thienyl)silanes ( I, II ) crystallize in different space groups, but their respective structural motifs…
The ultimate or end point of functional materials development is the realization of strong coupling between all energy regimes (optical, electronic, magnetic, and elastic), enabling the same material to be utilized for multifunctionalities. However, the integration of multifunctionalities in soft materials with the ex…
