A molecular dynamics (MD) based computational intelligence (CI) approach is proposed to investigate the Young modulus of two graphene sheets: Armchair and Zigzag. In this approach, the effect of aspect ratio, the temperature, the number of atomic planes and the vacancy defects on the Young modulus of two graphene shee…
The adsorption and tribological properties of graphene have received increasing attention for the further development of graphene-based coatings in applications. In this work, we performed first principles calculations with the inclusion of the nonlocal van der Waals correction to study the effect of graphene coating…
Four rare-earth metal complexes, [Ln(Ccbp)3(H2O)3]n (Ln = La (1), Ce (2), Pr (3) and Nd (4)) are synthesised from the ligand H2CcbpBr (H2CcbpBr = 4-carboxy-1-(4-carboxybenzyl)pyridinium bromide) and the respective lanthanide metal ions. Complexes 1–4 are isostructural in that every three Ccbp– ligands juxtapose two Ln…
In the present work we report low-threshold distributed feedback (DFB) lasing from electrically tunable holographic polymer–liquid crystal transmission gratings of POLIPHEM type doped with pyrromethene 567. Due to their uniform droplet-free micro-morphology, the POLIPHEM gratings possess high diffraction efficiency an…
A novel, highly active three-way catalyst, rhodium supported on Y- and La-added zirconia (Rh/Zr–Y–La–O), was found in this study.
The crystal structures and magnetic and electronic properties of three new hetero-bimetallic coordination frameworks, [Ru2(O2CR)4][Au(CN)2] (R = phenyl (1(Ph)), 2-furan (1(Furan)), and 2-thiophene (1(Thio)), have been characterised. Through variation of the functionalised carboxylate group, both the one-dimensional ch…
Encapsulation of guest molecules within the interior cavities of dendrimers is promising, but high generation dendrimers show limited encapsulation capacity due to their dense surface shell. Here, for the first time, we prove that high generation polyamidoamine dendrimers, such as generation 8 and generation 10, are a…
The major driving force for organogelation is known to be hydrogen bonding for gelators containing functional groups capable of forming hydrogen bond(s). In order to examine this, we have investigated the gelation behavior of two 4-(N-tetradecanoyl)aminohydroxybutanoic acid amphiphiles in a series of organic solvents…
An energy transfer cassette was reported with energy donor (pyrene) and energy acceptor (bisindolylmaleimide) incorporated together. The pyrene and bisindolylmaleimide units are connected through carbon-nitrogen single covalent bond. The intramolecular repulsion prevents the coplanarization of pyrene and bisindolylmal…
Abstract Porphyrins and metalloporphyrins are investigated extensively as potential anticancer drugs. They work as DNA binding agents as well as photosensitizers in photodynamic therapy. Conjugation of the macrocycle with organometallic complexes is a powerful tool to implement the water solubility of the adducts and…
Ferroelectric domain switching within individual nanoscale grains of a 100 nm thick polycrystalline PbZr0.2Ti0.8O3 thin film has been shown to depend on the relative crystallographic orientation of the adjacent grains. Using Piezoresponse Force Microscopy, the significance of local microstructure on the domain switchi…
Natural fibers have received considerable attention as a substitute for synthetic fiber reinforcements in thermoplastics. As replacements for conventional synthetic fibers like aramid and glass fibers, natural fibers are increasingly used for reinforcement in thermoplastics due to their low density, good thermal insul…
Industrial poly(vinyl chloride) (PVC) plastisols are often formulated using phthalate plasticizers due to their cost-effectiveness and high compatibility with PVC. However, there is a current need to replace these additives by plasticizers that (i) present reduced migration/leaching and volatilization profiles, (ii) c…
Localized self-assembly of conjugated polyelectrolytes (CPEs) in a film is realized by simply contacting the film to appropriate surfactant solutions. This in situ self-assembly allows simultaneous optical and structural reforming on the selected areas and highly resolved patterning of the CPE film.
In this work, dodecylamine-modified graphene nanosheets (DA-GNSs) and γ-aminopropyl-triethoxysilane-treated multiwalled carbon nanotubes (f-MWCNTs) are employed to prepare cyanate ester (CE) thermally conductive composites. By adding 5 wt% DA-GNSs or f-MWCNTs to the CE resin, the thermal conductivities of the composit…
This paper reports the effect of combined solution with different antibacterial substance on the total volatile basic nitrogen (TVB-N), total bacterial count (TBC), the sensory properties, pH, the weight loss rate of beef fillets stored at 4±1C. Main components of the solutions were as follows: (A1) Aseptic water, (A…
We present a study of the magnetic field tuned superconductor-to-insulator transition (SIT) in the electron gas that forms at the ${\mathrm{LaAlO}}_{3}$/${\mathrm{SrTiO}}_{3}$ interface. We find that the magnetic field induces a transition into a weakly insulating state, as is observed for the electrostatically tuned…
We show how the Butler-Volmer and Nernst equations, as well as Peltier effects, are contained in the general equation for nonequilibrium reversible and irreversible coupling, GENERIC, with a unique definition of the overpotential. Linear flux-force relations are used to describe the transport in the homogeneous parts…
Abstract In this study, plasma modification was carried out in barrier discharge under atmospheric pressure. Sulfur dioxide and/or sodium oxide was used as the coating precursor. The results show that the films treated with a mixture of argon and sulfur dioxide inhibited microbial growth considerably better than those…
In this study, the preparation of nylon 6/talc nanocomposites was studied by melt blending in a co-rotating twin-screw extruder having length/diameter ratio of 32:1 at a screw rotation speed of 100 r min −1 . Concentration of nanotalc was varied from 1 phr to 5 phr in nylon 6. The composite samples were subjected to a…
