Electrodeposition of polypyrrole on carbon nanotube-coated cotton fabrics for all-solid flexible supercapacitor electrodes
Polypyrrole and carbon nanotube were attached on cotton fabrics as electrodes to prepare all-solid, flexible supercapacitors.
Shedding light on an ultra-bright photoluminescent lamellar gold thiolate coordination polymer [Au(p-SPhCO 2 Me)] n
The first structure elucidation of a lamellar gold thiolate coordination polymer is described. [Au(p-SPhCO2Me)]n is obtained from the simultaneous esterification of mercaptobenzoic acid and reduction of the Au(iii) precursor. Despite the presence of aurophilic interactions, the intense phosphorescence (QY ∼ 70%) origi…
Electric, magnetic, piezoelectric and magnetoelectric studies of phase pure (BiFeO 3 –NaNbO 3 )–(P(VDF-TrFE)) nanocomposite films prepared by spin coating
(BiFeO <sub>3</sub> –NaNbO <sub>3</sub> )–(P(VDF-TrFE)) co-polymer thin films were fabricated by spin coating technique and their electric, magnetic, electromechanical and magnetoelectric properties were investigated.
Hard sphere packings within cylinders
Arrangements of identical hard spheres confined to a cylinder with hard walls have been used to model experimental systems, such as fullerenes in nanotubes and colloidal wire assembly. Finding the densest configurations, called close packings, of hard spheres of diameter σ in a cylinder of diameter D is a purely geome…
Strategy to improve phase compatibility between proton conductive BaZr 0.8 Y 0.2 O 3−δ and nickel oxide
Precisely controlling BaO activity and improving the compositional homogeneity of BZY20 suppress effectively formation of second phases of BaY <sub>2</sub> NiO <sub>5</sub> and Y <sub>2</sub> O <sub>3</sub> .
Dual emission in asymmetric “giant” PbS/CdS/CdS core/shell/shell quantum dots
Semiconducting nanocrystals optically active in the infrared region of the electromagnetic spectrum enable exciting avenues in fundamental research and novel applications compatible with the infrared transparency windows of biosystems such as chemical and biological optical sensing, including nanoscale thermometry. In…
Assessment of polydopamine coated magnetic nanoparticles in doxorubicin delivery
Magnetic nanoparticles coated with bioinspired polydopamine were obtained <italic>via</italic> a co-precipitation method and oxidative polymerization of dopamine. Obtained particle were used for carrying doxorubicin to HeLa cells.
Tuning the electronic and optical properties of phosphorene by transition-metal and nonmetallic atom co-doping
The electronic and optical properties of phosphorene co-doped with vanadium and non-metallic atoms (B, C, N and O) are investigated by employing first-principles calculations based on density functional theory.
Defect chemistry and relaxation processes: effect of an amphoteric substituent in lead-free BCZT ceramics
(BCZT) ceramics synthesized by a solid state reaction method. Structural investigations showed co-existence of two phases - tetragonal (P4mm) and rhombohedral (R3m) - for compositions with x ≤ 0.05 wt% Pr. Temperature dependent dielectric studies revealed two phase transitions - rhombohedral (R) → tetragonal (T) and T…
Synthesis of polydopamine-coated halloysite nanotube-based hydrogel for controlled release of a calcium channel blocker
A stimuli-triggered drug delivery vehicle has been synthesized by self-polymerization of dopamine (DA) on the outer surface of halloysite nanotubes (HNT) followed by gelation <italic>via</italic> alginate.
A series of organic–inorganic hybrid materials consisting of flexible organic amine modified polyoxomolybdates: synthesis, structures and properties
A series of hybrid materials consisting of Tris[(2-pyridyl)methyl]amine modified polyoxomolybdates were obtained and some complexes have efficient photocatalytic activities to degrade pararosaniline hydrochloride dye molecules.
Dynamic fluid-film interferometry as a predictor of bulk foam properties
Understanding and enabling the control of the properties of foams is important for a variety of commercial processes and consumer products. In these systems, the role of surface active compounds has been the subject of many investigations using a wide range of techniques. The study of their influence on simplified geo…
Modelling of Supercapacitors: Factors Influencing Performance
The utilizable capacitance of Electrochemical Double Layer Capacitors (EDLCs) is a function of the frequency at which they are operated and this is strongly dependent on the construction and physical parameters of the device. We simulate the dynamic behavior of an EDLC using a spatially resolved model based on the por…
Inhibition of Corrosion of Carbon Steel in 3.5% NaCl Solution byMyrmecodia PendansExtract
Inhibitor is a substance that is added to the corrosive media to inhibit corrosion rate. Organic inhibitors are preferred to inorganic ones since they are environmentally friendly. One of the organic compounds which is rarely reported as a corrosion inhibitor is Myrmecodia Pendans . The organic compounds can be adsorb…
Charge compensation assisted enhancement of photoluminescence in combustion derived Li + co-doped cubic ZrO 2 :Eu 3+ nanophosphors
Doping of a Eu <sup>3+</sup> for a tetravalent ion (Zr <sup>4+</sup> here) creates charge imbalance in the system that results in vacancies in the ZrO <sub>2</sub> lattice. Here, charge compensation is achieved by replacement of one Zr <sup>4+</sup> ion by a Eu <sup>3+</sup> and a Li <sup>+</sup> .
