In a two-step process, polyelectrolytes are added to existing layer-by-layer (LbL)-constructed polyelectrolyte multilayer films (PEMs), generating versatile new films as well as fundamental insights into LbL assembly mechanisms. First, PEM swelling is affected by exposure to aqueous salt solutions of high concentratio…
The molecular turnstile 1 composed of a stator based on an Sn(IV)-porphyrin bearing two sets of monodentate coordinating sites (pyridyl and benzonitrile) and a handle bearing a 2,6-pyridinediamide moiety as a tridentate unit was synthesised. In the absence of metal behaving as a blocking agent, the handle freely rotat…
Our work reports a facile route to colloidal Te nanocrystals with binary uniform size distributions at room temperature. The binary-sized Te nanocrystals were well separated into two size regimes and assembled into films by electrophoretic deposition. The research provides a new platform for nanomaterials to be effici…
The objective of this study was to investigate an inorganic nanoparticle impregnation (INI) technique to improve the compatibility between kenaf bast fibers and polyolefin matrices. The Scanning Electron Microscopy (SEM) was used to examine the surface morphology of the INI-treated fibers showing that the CaCO 3 nanop…
Three sets of a new class of low surface tension block copolymers were synthesized consisting of a poly(dimethylsiloxane) (PDMS) block and a poly(perfluorooctylethyl acrylate) (AF8) block. The polymers were prepared using a bromo-terminated PDMS macroinitiator, to which was attached an AF8 block grown using atom trans…
The reactions of manganese(II) acetate or perchlorate, sodium azide or sodium cyanate, and the zwitterionic dicarboxylate ligand 1,4-bis(4-carboxylatopyridinium-1-methylene)benzene (L) under different conditions yielded three different Mn(II) coordination polymers with mixed carboxylate and azide (or cyanate) bridges:…
We fabricated dextran-coated magnetic nanoclusters (Dex-MNCs) for targeted magnetic resonance (MR) imaging of inflammatory macrophages. Dex-MNCs were prepared through encapsulation of hydrophobic magnetic nanocrystals (MNCs) by pyrenyl dextran in order that MNCs could achieve increased colloidal stability in aqueous p…
The effects of Nb addition on phase, microstructure and electrical properties of barium titanate ceramics were investigated. Nb-doped barium titanate ceramics (BaTi1-xNbx)O3, x = 0 to 0.02) were prepared by conventional mixed-oxide method. All barium titanate compositions show tetragonal perovskite structure. Low Nb c…
An emitting nanoassembly composed of a novel amphiphilic cyclodextrin functionalised with a covalently appended fluorophore and an anionic porphyrin internalizes effectively in tumor cells, allowing simultaneously the detection of carrier and photosensitiser.
The magnetization of FeSe1−xTex (x∼0, 0.5, and 1.0) compounds has been studied in magnetic fields up to 50kOe and at temperatures of 2–300K. The superconducting transition was observed at Tc∼8K and 13.6–14.2K in FeSe0.963 and FeSe0.5Te0.5, respectively. For most of the samples, nonlinearity of the magnetization curves…
Classical core loss models such as two components model or modified Steinmetz model are still popular and used by engineers to loss prediction in electrical machines. They may carry to increase discrepancy between calculated and measured values. This discrepancy increases with grain-orientation and with increasing dis…
The study was carried out to assess the nutritional value and mineral contents of four medicinal plants viz., Aerva javanica Burm.f, Calotropis procera Ait. f, Datura alba Nees, and Nepeta suavis Stapf., which are traditionally used as medicine in the Northwest Pakistan. Proximate analysis of plant sample determines t…
The discovery that the conductivity of conjugated organic polymers can be controlled through oxidation or reduction led to materials combining the electronic properties of metals with the weight and density of plastics. For this reason, such materials have been studied extensively and their importance recognized with…
Plastic pollution is creating the significant environmental and economic burdens since they consume the natural fuels (energy) and other natural resources. Beside this, they have long shelf time, debasing the environment in the numerous ways. The only way to trim down the hazards of plastic pollution is to decrease th…
The paper presents a detailed analysis of the physico-chemical effects of acoustic cavitation used in food processing. The mechanism of interaction between acoustic cavitation and food media is discussed. An overview of recent studies carried out on dairy processing using acoustic cavitation is provided. The acoustic…
Here we report the in vitrobiomineralization of SrCO3 complex nanostructures obtained using glucosan as the modifier in dimethyl formamide (DMF)–deionized water (DIW) mixed solvents. Rod-, dendrite-, dumbbell-, and sphere-like SrCO3 nanostructures were achieved by tuning the volume ratios of DMF/DIW, reaction time, an…
Solid oxide cells (SOCs) are potentially useful for versatile energy conversion and storage applications. This work demonstrates the feasibility of SOCs that are operated in alternate power generation and carbon conversion modes. SOCs with lanthanum strontium vanadate (LSV) hydrogen electrodes have been proved to be c…
{Mo(132)} Keplerate anion reacts with tellurites to give a soluble precursor to produce in hydrothermal conditions single-phase M1 MoVTeO light-alkanes oxidation catalyst. Characterization of this Te-containing intermediate by single-crystal X-ray diffraction, (125)Te NMR, UV-visible and redox titration reveals a moly…
Silver nanoparticles with a tuneable λ max were produced as colloids by heterogeneous nucleation. The synthesis process is both fast and repeatable, producing stable PVA capped nanoparticles. The colloid's effectiveness in the SERRS system was investigated using Rhodamine 6G, R6G, Crystal Violet, CV, and Malachite Gre…
A solid oxide fuel cell was developed with BaZr0.7Pr0.1Y0.2O3-δ, a proton-conducting electrolyte showing high conductivity, and good sinterability and chemical stability. A maximum power density of 163 mW cm−1 at 600 °C was achieved combining BZPY10 with tailored electrodes; a composite anode promoting the electrolyte…
