Calotropis procera (family: Asclepiadaceae) contains cardiac glycosides which are cytotoxic to cancer cells. The extracts of C. procera have been reported to be cytotoxic to many cancer cell lines and this is the first report against the human skin melanoma cells (SK-MEL-2). The SK-MEL-2 cells treated with C. procera…
Newly developed methods for time-resolved studies using the polychromatic and in particular the pink-Laue technique, suitable for medium and small-size unit cells typical in chemical crystallography, are reviewed. The order of the sections follows that of a typical study, starting with a description of the pink-Laue t…
Abstract A mixed lanthanide complex was synthesized hydrothermally with two kinds of organic ligands, adenine and biphenyl‐4,4′‐dicarboxylic acid, and is formulated as Ad/Tb0.999Eu0.001/BPDC (Ad = adeninate, BPDC = biphenyl‐4,4′‐dicarboxylate). The photophysical properties, especially the fluorescent sensing propertie…
Two-internal variable thermodynamics model is presented to investigate the evolution of microstructure and flow stress during severe plastic deformation. Previous studies have shown that due to heterogeneous distribution of dislocations during severe plastic deformation, the use of multivariable models is needed. In t…
Single crystals of ScUS3 were synthesized in high yield in a single step at 1173 K. ScUS3 crystallizes in the FeUS3 structure type in the space group D2h(17)–Cmcm of the orthorhombic system with four formula units in a cell of dimensions a = 3.7500(8) Å, b = 12.110(2) Å, and c = 9.180(2) Å. Its structure consists of e…
The mechanical properties and hydrogen embrittlement susceptibility of 7075 aluminium alloy were studied by means of cathodic H permeation, hydrogen determinator, slow strain rate test (SSRT), energy dispersive X-ray spectroscopy (EDS) and scanning electron microscope (SEM). The results showed that both before and aft…
Surface enhanced Raman scattering (SERS) on eight-fold quasicrystal arrays with precisely controlled size and spacing fabricated via electron beam lithography was investigated. This SERS substrate shows high efficiency at 785 nm excitation in the detection of p-mercaptoaniline (pMA), and a SERS enhancement factor (EF…
Recent angle-resolved photoemission reveals that the doping level in some ${\mathrm{BiS}}_{2}$-based superconductors is much lower than the nominal one. Here we determine the pairing function at such a realistic low doping level by a functional renormalization group (FRG) and study the resulting physical properties by…
Abstract BACKGROUND Phosphorylated proteins have attracted widespread attention due to their crucial roles in regulating biological processes. Therefore, development of effective methods for identification and detection of phosphorylated proteins is an indispensable step to understand the roles of protein phosphorylat…
Abstract We consider a non-local isoperimetric problem arising as the sharp interface limit of the Ohta–Kawasaki free energy introduced to model microphase separation of diblock copolymers. We perform a second order variational analysis that allows us to provide a quantitative second order minimality condition. We sho…
A novel inorganic nanocomposite material, called BOA, which has the form of small building blocks composed of gold nanoparticles embedded in a polyoxoborate matrix, is presented. It is demonstrated that cotton wool decorated with the BOA nanocomposite displays strong antibacterial activity toward both Gram-positive an…
The conduction through unintentionally doped ZnO nanowires grown by metalorganic chemical vapor deposition versus temperature (4 to 300 K) and nanowire radius (50 to 175 nm) was investigated. To obtain a reliable picture of the electrical conduction, controlled experimental conditions were used to master the influence…
Room-temperature fabricated ZnO/ST-cut quartz is adopted for SAW ultraviolet (UV) photodetector. The ST-cut quartz substrate and ZnO layer are used for SAW excitation and photodetection, respectively. High resolution x-ray diffraction (XRD) and photoluminescence (PL) measurement indicate that high quality ZnO films ca…
As excellent nonlinear optical (NLO) crystals, YCa(4)O(BO(3))(3) (YCOB) and GdCa(4)O(BO(3))(3) (GdCOB) have been paid much attention since their first appearance in 1990's. From that time to now, almost all of related researches and applications have focused on their type-I phase-matching (PM) configurations which pos…
Successful protein crystallization screening experiments are dependent upon the experimenter being able to identify positive outcomes. The introduction of fluorescence techniques has brought a powerful and versatile tool to the aid of the crystal grower. Trace fluorescent labeling, in which a fluorescent probe is cova…
In a previous publication ( Macromolecules 2012, 45, 7237), a stochastic model of the glassy state that acknowledges dynamic heterogeneity was shown to describe the classic Kovacs poly(vinyl acetate) volume relaxation data set with the exception of the expansion gap and the pressure dependence of the glass transition…
A clean and sustainable deicing additive was prepared via the adsorption of acetate anions (Ac-) by magnesium (Mg) and aluminum (Al) calcined layered double hydroxide (Mg/Al-CLDH). Fourier transform infrared spectroscopy spectrums proved that Ac- had intercalated into LDH structure. X-ray diffraction patterns, scannin…
In this study, we present a nanoengineered therapeutic-releasing system based on aluminum wires featuring nanoporous anodic alumina layers and chitosan coatings. Nanoporous anodic alumina layers are produced on the surface of aluminum wires by electrochemical anodization. These nanoporous layers with precisely enginee…
Precise control over the geometry and chemistry of multiphasic particles is of significant importance for a wide range of applications. In this work, we have developed one of the simplest methodologies for fabricating monodisperse, multiphasic micro- and nanoparticles possessing almost any composition, projected shape…
Hybridization of carbon nanotubes (CNT) with graphene provides a promising means of integrating the attributes of both materials, thereby enabling widespread application. Here, we present a method to directly assemble hybrid CNT-graphene films by a blown bubble method combined with selective substrate annealing. We us…
