In this paper, we report the synthesis, structure, and electrical conductivity of a novel series of Mo and rare earth (RE = Y, Sm, Gd)-doped compounds of the nominal chemical formula of Ce0.9−x RExMo0.1O2.1–0.5x (x = 0.2, 0.3) (CRMO). The formation of cubic fluorite-like structure was confirmed by powder X-ray diffrac…

The structure and luminescence properties of a well-known trinuclear Au(i) imidazolate complex are determined for the first time along with its interaction with the organic π acid perfluoronaphthalene in the solid state and solution.
Surface-Initiated Atom Transfer Radical Polymerization (SI-ATRP) has been exploited to hydrophilize PEEK. The ketone groups on the PEEK surface were reduced to hydroxyl groups which were converted to bromoisobutyrate initiating sites for SI-ATRP. The modification steps were followed by contact angle measurements and X…
Crystal engineering of pharmaceuticals through co-crystallization provides a new strategy for altering the physical and chemical properties of solid forms of active pharmaceutical ingredients (APIs). The understanding of structure–property relationship of co-crystals containing chiral pharmaceutical agent (PA) and co-…
We use the hyper-netted chain approximation of liquid state theory to analyze the evolution with density of the pair correlation function in a model of soft spheres with harmonic repulsion. As observed in recent experiments on jammed soft particles, theory predicts an ‘anomalous’ (nonmonotonic) evolution of the intens…
We have investigated emulsions stabilised solely by partially-hydrophobised fumed silica particles which consist of a mixture of primary particles and irregularly-shaped fused aggregates and larger agglomerates. The particle wettability is controlled by varying the extent of hydrophobisation of their surfaces. This, i…
The process of hydrogen desorption from graphane (graphene sheet saturated by hydrogen adsorbed from both sides) has been studied using the method of molecular dynamics. The temperature dependences of the time of desorption onset for various hydrogen coverages on graphene are calculated and the corresponding activatio…
A phase field model based on the time-dependent Ginburg–Landau equation (TDGL) is developed to investigate the electrocaloric effect (ECE) of PbZr0.8Ti0.2O3 (PZT) thin film with a multidomain structure. The rhombohedral domain morphology is obtained through numerically solving the TDGL equation with periodic boundary…
Nanoliposome can be designed as a drug delivery carrier to improve the pharmacological and therapeutic properties of drug administration. (188)Re-labeled nanoliposomes are useful for diagnostic imaging as well as for targeted radionuclide therapy. In this study, the in vivo nuclear imaging, pharmacokinetics and biodis…
We present the one-dimensional polymeric structures of [Cu(SePh)]∞1 and [Cu(SeMe)]∞2 that were solved by using powder X-ray diffraction data. Using a field-effect transistor (FET) set-up, the hole mobility of complex 1 was found to be 4 × 10−2 cm2 V−1 s−1, comparable to that of regioregular poly(3-hexylthiophene) (P3H…
By means of molecular dynamics simulations, we study the structure and the dynamics of a microscopic model for colloidal gels at low volume fractions. The presence of directional interactions leads to the formation of a persistent interconnected network at temperatures where phase separation does not occur. We find th…
Full control in size distribution and surface chemistry of Si nanocrystals (NCs) allows the high efficiency of visible light emission. The NC synthesis and subsequent surface modification with organic monolayers are performed in a single step by laser chemical method. Interestingly, it is found that the distinct emiss…
Two linear cobalt chloride ferromagnetic chains, trans-[CoCl2(3,5-X2py)2] [X = Cl (1), Br (2)], have been prepared and the influence of the halogen bonding on the interchain magnetic interactions has been investigated.
White-light long-lasting phosphor Sr 2 Al 2 SiO 7 : Ce 3 + , Dy 3 + was prepared by a high temperature solid-state reaction. The energy transfer between Ce 3 + and Dy 3 + was systematically investigated. Through co-doped Ce 3 + and Dy 3 + , the duration of the persistent luminescence of Sr 1.975 Al 2 SiO 7 : Ce 0.005…
Thermoresponsive shape memory polymers are stimuli-responsive materials whose shape is modulated by heat. They have been investigated as smart materials in a variety of biomedical, industrial and aerospace applications. The vast majority of shape memory polymers have been limited to those prepared from organic polymer…
Anode-supported solid oxide fuel cells ͑SOFCs͒ based on Ni-yttria-stabilized zirconia ͑YSZ͒ anodes, YSZ electrolytes, and lanthanum strontium manganite ͑LSM͒-YSZ cathodes were studied with respect to durability in humid air ͑ϳ4%͒ typically over 1500 h.Operating temperature and current density were varied between 750 a…
PURPOSE: Two points are particularly relevant for the clinical use of magnetic nanoparticle hyperthermia: the optimisation of both the exposure conditions and the magnetic nanoparticle characteristics, and the assessment of the limits of scalability of the treatment. To answer these two points a criterion for the indi…
Historically the extraction of high-quality crystallographic information from inorganic samples having high hydrogen contents, such as metal hydrides, has involved preparing deuterated samples prior to study using neutron powder diffraction. We demonstrate, through direct comparison of the crystal structure refinement…
The normal and anion structures of salicylaldehyde azine (SAA) in solvents of different viscosities and polarities have been studied by means of femto- to nanosecond time-resolved emission techniques. In the normal form, an excited-state intramolecular proton-transfer (ESIPT) reaction takes place with a time constant…
