Abstract A bis(β‐diketone), 1,3‐bis(4,4,4‐trifluoro‐1,3‐dioxobutyl)phenyl (BTP), which contains a trifluorinated alkyl group, has been exploited to obtain three series of visible‐light sensitive dinuclear rare‐earth complexes with the general formula [Ln 2 (BTP) 3 L 2 ] [Ln = Nd, L = DME ( 1 ), bpy ( 2 ), and phen ( 3…
The non-linear magnetoelectric (ME) effect of Metglas/Pb(Mg1/3Nb2/3)O-3-PbTiO3 heterostructures has been studied. Such effect holds promise for modulation mode ME sensor applications that require no dc bias. The non-linear ME coefficient was found to be highly dependent on the derivative of the piezomagnetic strain co…
Currently available investigations of the isotope effect in Fe-based superconductors are all based on macroscopic resistivity and susceptibility measurements and results are highly controversial. Here we present an investigation of the Fe isotope effect in the (Ba, K)Fe 2 As 2 superconductor by temperature-dependent E…
The room temperature deposited ZnO:H thin films having high conductivity of 500 Ω−1 cm−1 and carrier concentration reaching 1.23 × 1020 cm−3 were reactively sputter deposited on glass substrates in the presence of O2 and 5% H2 in Ar. A metal-semiconductor transition at 165 K is induced by the increasing hydrogen incor…
Engineering interfaces in perovskite/spinel heterostructures is challenged by structural differences. We have used kinetic growth limitations to fabricate flat BaTiO3/CoFe2O4 (BTO/CFO) epitaxial bilayers on La2/3Sr1/3MnO3/SrTiO3(001). In situ analysis of lattice strain during growth has revealed that BTO grows relaxed…
We present a method for efficiently recomputing rates in a kinetic Monte Carlo simulation when the existing rate catalog is modified by the presence of a strain field. We use the concept of the dipole tensor to estimate the changes in the kinetic barriers that comprise the catalog, thereby obviating the need for recom…
Lewis acidic organic ionic liquids provide a novel synthetic medium to prepare new semiconducting chalcogenides, [(Bi4Te4Br2)(Al2Cl5.46Br0.54)]Cl2 (1) and [Bi2Se2Br](AlCl4) (2). Compound 1 features a cationic [(Bi4Te4Br2)(Al2Cl5.46Br0.54)](2+) three-dimensional framework, while compound 2 consists of cationic layers o…
Despite the rapid developments in recent nanocrystal research and their expanding applications, the evolution mechanism of nanocrystals remains veiled for the most part due to the lack of appropriate analytical techniques. Here we demonstrate one promising multi-spectroscopic approach for the in situ investigation of…
It takes two different functional additives to produce the title structures. The proposed mechanism based on the nonclassical particle-mediated crystallization of calcium carbonate demonstrates the individual and cooperative effects of the polymer poly(sodium 4-styrenesulfonate) and small folic acid molecules on the f…
It was previously reported that the synthesis of silver based delafossites as pure phases is challenging and requires more often delicate preparations as ion-exchange rather than simple solid state reaction or hydrothermal synthesis. For the first time, polycrystalline AgCrO 2 samples are synthesized by a one-step rea…
We present CCSD(T) interaction energies and the bonding analysis for complexes of Cu, Ag, and Au with the lone-pair ligands H2O, OF2, OMe2, NH3, NF3, NMe3, H2S, SF2, SMe2, PH3, PF3, PCl3, and PMe3 (ML complexes). Both electron correlation and relativistic effects are crucial in the bonding of all complexes. AuPH3, AuP…
Abstract Computational data mining is of interest in the pharmaceutical arena for the analysis of massive amounts of data and to assist in the management and utilization of the data. In this study, a data mining approach was used to predict the miscibility of a drug and several excipients, using Hansen solubility para…
Recently, increasing number of studies are performed on protective fabrics containing metal wires for electromagnetic shielding purposes. In the present paper, the hybrid fabrics in plain and rib structures were knitted by using single and double ply hybrid yarns obtained by acrylic (PAC) yarns plied with stainless st…
A Wittig reaction was employed to synthesize conjugated BODIPYs in high yields by treating formylated BODIPYs with alkyl/aryl ylides under simple room temperature conditions. Treatment of 3,5-diformyl BODIPYs or α-formyl 3-pyrrolyl BODIPY with different alkyl/aryl ylides in CH2Cl2 at room temperature for 2 h followed…
Atomic-scale quantification of chemical composition across oxide interfaces is important for understanding physical properties of epitaxial oxide nanostructures. Energy-dispersive X-ray spectroscopy (EDS) in an aberration-corrected scanning transmission electron microscope was used to quantify chemical composition acr…
Fabrication, via electrospinning, and characterization of an ultrafine structure architected from a blend of hydrophobic zein and hydrophilic chitosan (CS) were conducted. Poly(ethylene oxide) (PEO) and nonionic surfactant, namely, Tween 40, were employed to improve the electrospinnability of the blend, while ethanol…
Self-assembled vertical epitaxial nanostructures form a new class of heterostructured materials that has emerged in recent years. Interestingly, such kind of architectures can be grown using combinatorial processes, implying sequential deposition of distinct materials. Although opening many perspectives, this combinat…
In this study, we report a facile synthesis of silver nanoparticle having SERS and antimicrobial activity using bacterial exopolysaccharide (EPS). Bacillus subtilis (MTCC 2422) was grown in nutrient broth and the extracellular EPS secreted by the organism was extracted and purified. The purified EPS was used for the s…
The control of crystal size of any crystallization process is especially important in the pharmaceutical industry where small sizes are often desired. Seeding is often used as a method of controlling crystal size and suppressing primary nucleation in batch processes. The continuous mixed suspension mixed product remov…
The photoluminescence (PL) of size-purified silicon nanocrystals is measured as a function of temperature and nanoparticle size for pure nanocrystal films and polydimethylsiloxane (PDMS) nanocomposites. The temperature dependence of the bandgap is the same for both sample types, being measurably different from that of…
