By using a hydrostatic pressure, we have successfully tuned the normal state property and superconductivity in ${\mathrm{LaO}}_{0.5}{\mathrm{F}}_{0.5}{\mathrm{BiSe}}_{2}$ single crystals. It is found that, with the increase of pressure, the original superconducting phase with ${T}_{c}\ensuremath{\sim}3.5$ K can be tun…
To monitor water quality and investigate relationships between downstream nutrient increases and diatom communities in the Pardo River Basin, Brazil, water and diatom samples were collected between 2005 and 2009. There were significant differences in diatom community composition among all river zones, with the greates…
Cellulose woven (CW) was surface treated by means of hexadecyltrimethylammonium bromide surfactant (HTAB) in aqueous solution medium at elevated temperature. The parameters of the surface treatment that have been studied are HTAB concentration (0.2, 0.4, 0.6, 0.8 and 1.0 wt%) and treatment time (1, 2, 3, 4 and 5 h). T…
We investigated the room temperature oxidation of ultra-thin Ni and Cr films grown on Fe(0 0 1). In particular, we characterized the degree of crystallinity and the stoichiometry of the oxide layers and addressed the chemical stability of the interface with the highly reactive Fe substrate by means of low-energy elect…
This review covers methods and recent developments of the theoretical study of domain structures in ultrathin ferroelectric films. The review begins with an introduction to some basic concepts and theories (e.g., polarization and its modern theory, ferroelectric phase transition, domain formation, and finite size effe…
The lateral variation of the tunnel magnetoresistance (TMR) of a graphene-based vertical heterostructure is studied by spin-polarized scanning tunneling microscopy (SP-STM) using an Fe-coated probe tip. The well-defined heterostructure is obtained by the intercalation of a magnetic Fe monolayer at the graphene/Ir(1 1…
Abstract Bioactive edible coatings based on chitosan ( C h) were developed by incorporating clove oil ( CO ) and/or ethylenediaminetetraacetate ( E ), with the aim of promoting the microbial quality of meat. The antimicrobial mode of C h‐based coatings was also explored in terms of membrane permeability. Results showe…
ABSTRACT Ionic liquids have attracted a considerable attention as the next generation electrolytes for energy devices. We have developed new free‐standing and nanostructured polymer films in which ionic liquids are confined into one‐dimensionally ordered nanochannels. These polymer films have been obtained by photopol…
We propose an analytical description of the role of local depolarization fields in the terahertz conductivity of nanostructured samples and demonstrate this approach in a sample composed of silicon nanocrystals. This helps to uncover the nature of charge carrier transport at nanoscale. Time-resolved terahertz conducti…
A major issue in chemotherapy is the lack of specificity of many antitumor drugs, which cause severe side effects and an impaired therapeutic response. Here we report on the design and characterization of model tumor activated prodrug-conjugated polystyrene (PS) nanoparticles (TAP-NPs) for the release of doxorubicin (…
We present results from ab-initio, self-consistent density functional theory calculations of electronic and related properties of zinc blende boron phosphide (zb-BP). We employed a local density approximation potential and implemented the linear combination of atomic orbitals formalism. This technique follows the Baga…
Chicken eggshell (ES) is an aviculture byproduct that has been listed worldwide as one of the worst environmental problems. It constituted by a three-layered structure, namely the cuticle on the outer surface, a spongy (calcareous) layer and an inner lamellar (or mammillary) layer. The chemical composition (by weight)…
Improved performance by texturing has become attractive in the field of lead‐free ferroelectrics, but the effect depends heavily on the degree of texture, type of preferred orientation, and whether the material is a rotator or extender ferroelectric. Here, we report on successful texturing of K 0.5 Na 0.5 NbO 3 ( KNN…
Hyperglycemia, hyperlipidemia and inflammation are key risk factors for atherosclerosis and can lead to overproduction of reactive oxygen species (ROS), which plays a critical role in vascular endothelial dysfunction and subsequent progress of atherosclerosis. However, there is currently a lack of effective drugs that…
The aim of this research paper is to study the effect of particle size of recycled polymeric material to mechanical tensile properties. During grinding particles are formed which have a different size, shape and surface, from larger pieces to dust particles. During processing these particles melt at different rates de…
Abstract Die drei neuartigen, diskreten Palladium(II)‐Oxocluster [CaPd 12 O 8 (PhAsO 3 ) 8 ] 6− ( CaPd 12 ), [SrPd 12 O 6 (OH) 3 (PhAsO 3 ) 6 (OAc) 3 ] 4− ( SrPd 12 ) und [BaPd 15 O 10 (PhAsO 3 ) 10 ] 8− ( BaPd 15 ), bei denen die Erdalkalimetallionen im Innern einer kapselförmigen Struktur vorliegen, wurden hergestel…
Identity certification in the cyberworld has always been troublesome if critical information and financial transaction must be processed. Biometric identification is the most effective measure to circumvent the identity issues in mobile devices. Due to bulky and pricy optical design, conventional optical fingerprint r…
How the long-range ordering and local defect configurations modify the electronic structure of graphene remains an outstanding problem in nanoscience, which precludes the practical method of patterning graphene from being widely adopted for making graphene-based electronic and optoelectronic devices, because a small v…
The synthesis and photochemical study of novel nonsymmetrical 1,2-dithienylethenes (DTEs) with a maleimide bridge have been carried out. The synthetic approach to the DTEs was based on successive selective palladium-catalyzed cross-coupling reactions of 5-susbtituted-2-methyl-3-thiophenyl indium reagents with 3,4-dich…
Abstract Sugar moieties were incorporated into cross‐linked polyurethane (PUR) networks in an effort to achieve self‐repairing in the presence of atmospheric carbon dioxide (CO 2 ) and water (H 2 O). When methyl‐α‐ D ‐glucopyranoside (MGP) molecules are reacted with hexamethylene diisocyanate trimer (HDI) and polyethy…
