We present a theory of open- and closed-aperture Gaussian beam Z-scan for nonlinear optical materials with saturable absorption and high-order nonlinear refraction. We show that an approximate expression for a transmitted intensity through the nonlinear optical material is possible by means of the Adomian’s decomposit…
Novel star-shaped poly(ϵ-caprolactone)-b-poly(2-hydroxyethyl methacrylate) (sPCL-b-PHEMA) with 3 arm and 6 arm was synthesized by a combination of ring-opening polymerization and atom transfer radical polymerization. The structure of copolymers was confirmed by nuclear magnetic resonance ((1)H and (13)C NMR) and Fouri…
First results obtained with IMS Nanofabrication's 50-keV proof-of-concept electron multibeam mask exposure tool (eMET POC) are presented. The eMET POC was designed from scratch to meet the requirements of the 11-nm half-pitch node and already features the same column as future high volume manufacturing (HVM) tools. Al…
Abstract The aim of this work was to evaluate the influence of the operating conditions on the coating efficiency for urea coated in a spouted bed and to analyse the decrease of nitrogen volatilisation for the coated urea. Coating efficiencies in the range (from 44.24% to 73.7%) were obtained for the different process…
The synthesis, comprehensive linear photophysical characterization, two-photon absorption (2PA), steady-state and time-resolved stimulated emission depletion properties of a new fluorene derivative, (E)-1-(2-(di-p-tolylamino)-9,9-diethyl-9H-fluoren-7-yl)-3-(thiophen-2-yl)prop-2-en-1-one (1), are reported. The primary…
Metal oxide based minerals naturally contain transition metal impurities isomorphically substituted into the structure that can alter the structural and electronic properties as well as the reactivity of these metal oxides. Natural α-Al(2)O(3) (corundum) can contain up to 9.17% (w/w) Fe(2)O(3) and 1.81% (w/w) of Cr(2)…
Most helix-coil transition theories can be characterized by three parameters: energetic, describing the (free) energy cost of forming a helical state in one repeating unit; entropic, accounting for the decrease of entropy due to formation of the helical state; and geometric, indicating how many repeating units are aff…
A simple biomechanical test with real-time displacement and strain mapping is reported, which provides displacement vectors and principal strain directions during the mechanical characterization of heart valve tissues. The maps reported in the current study allow us to quickly identify the approximate strain imposed o…
Atomic force microscopy (AFM) combined with unroofing techniques enabled clear imaging of the intracellular cytoskeleton and the cytoplasmic surface of the cell membrane under aqueous condition. Many actin filaments were found to form a complex meshwork on the cytoplasmic surface of the membrane, as observed in freeze…
An extremely acidophilic sulfur-oxidizing bacterium was isolated from an industrial-scale bioheap of the Zijinshan copper mine and was named ZJJN. A tuft of flagella and a layer of thick capsule outside the cell envelope were clearly observed under transmission electron microscopy (TEM), which might be closely related…
We investigated a hematite $\ensuremath{\alpha}$-Fe${}_{2}$O${}_{3}$/permalloy Ni${}_{80}$Fe${}_{20}$ bilayer film where the antiferromagnetic layer consisted of small hematite grains in the 2 to 16 nm range. A pronounced exchange bias effect occurred below the blocking temperature of 40 K. The magnitude of exchange b…
In this study, we reported the fabrication of a transparent resistive random access memory device based on the Ag/HfO 2 /indium tin oxide (ITO) capacitor structure and its resistive switching characteristics. The X-ray diffraction and Fourier transform infrared spectra demonstrated that the as grown HfO 2 thin films w…
The insertion of transgenes into the plastid genome (plastome) has proved to be an effective alternative to nuclear transformation for producing stable transformants expressing heterologous proteins. Recently, methodology, characteristics, and possible fields of application of plastome transformation have been extensi…
In order to truly unlock advanced applications of single-walled carbon nanotubes (SWNTs), one needs to separate them according to both chirality and handedness. Here we show that the chiral D-ribityl phosphate chain of flavin mononucleotide (FMN) induces a right-handed helix that enriches the left-handed SWNTs for all…
RATIONALE: Despite advances in mass spectrometry (MS)-based identification, effective phosphopeptide enrichment is a prerequisite towards comprehensive phosphoproteomic analysis. Based on the different binding affinities and coordination geometries of the Ti(4+) and Fe(3+) ions with the phosphate group, we report a co…
Polycrystalline mullite-type PbMBO 4 (M = Al, Ga, Fe and Mn) samples were produced using the glycerin method [1]. The lattice thermal expansion of the materials was studied by temperature-dependent X-ray powder diffraction data Rietveld refinements. The crystal structure was refined in the space group Pnam following m…
Abstract Reported are the synthesis and structural characterization of Ce5Mg8Ge8 (its own structure type), CeMg2–xGe2+x (BaAl4‐type structure), RE4Mg7Ge6 (RE = Ce–Nd, Sm; La4Mg7Ge6‐type structure), and RE4Mg5Ge6 (RE = Ce, Pr; Tm4Zn5Ge6‐type structure). The structures of these compounds have been established by single‐…
The present study describes the development and evaluation of a novel biocompatible dendrimer-based nano drug delivery system which is readily soluble in water prepared by condensing Phloroglucinol and Succinic Acid (PGSA) and could efficiently encapsulate a well known hydrophobic photodynamic therapy (PDT) agent, pro…
Oxazolination of C(70) has been achieved via the aerobic oxidation of C(70)(2-) in the presence of PhCN. Only one C(70) oxazoline regioisomer (1) is obtained, indicating that the oxazolination of C(70)(2-) occurs with an unusual regioselectivity. Further benzylation of 1(2-) with benzyl bromide leads to the formation…
We present a density functional investigation of the surface effects on the catechol sensitization of selected hexagonal semiconductors (SiC, GaN, InN, CdS, CdSe). The atomic relaxation, the ionicity, and the reactivity, which characterize the selected substrates, are found to crucially influence both the bonding geom…
