Next generation graphene-based electronics essentially need a dielectric layer with several requirements such as high flexibility, high transparency, and low process temperature. Here, we propose and investigate a flexible and transparent poly-4-vinylphenol and poly(melamine-co-formaldehyde) (PVP/PMF) insulating layer…

Spray drying was explored as a new CsH <sub>2</sub> PO <sub>4</sub> nanoparticle synthesis method and a systematic parameter study was conducted to discover the set for high deposition rate and small particle sizes for solid acid fuel cell electrodes.
Three novel tin(iv)corrole complexes have been prepared and characterized by various spectroscopic techniques including single crystal X-ray structural analysis. Packing diagrams of the tin(iv)corroles revealed that corrolato-tin(iv)-chloride molecules are interconnected by intermolecular C-HCl hydrogen bonding intera…
Structural, thermodynamic and mechanical properties of monolayer hexagonal graphene sheet are studied using Classical Molecular Dynamics (MD) simulation under pressure and varying temperature. We used a tersoff interatomic potential, tuned mainly for layered structures. The potential gives structurally and mechanicall…
Simultaneously oxidizing and ultrasonicating graphite for 60 min can create high-structural integrity yet solution-processable graphene for a great many applications.
A mixture of NaOH and Na2SO3 was used in modification of banana stem fibers (BSF). Unidirectional BSF reinforced natural rubber (NR) lamina composites were made using compression moulding method. The results of the tensile loading in 0°, 45° and 90° to the fiber directions of the composite with fiber mass fraction of…
Si-Mo ductile cast irons are used to fabricate the exhaust manifolds of the internal combustion engines of large series cars. The maximum pointwise temperature at full engine load may be higher than 750 °C, and the main damage mechanisms in service are high-temperature oxidation and thermo-mechanical fatigue. The mech…
Water-soluble, highly emissive, color-tunable, and stable Cu:ZnSeS/ZnS core/shell doped nanocrystals (d-dots) with pure dopant emission have been synthesized through a simple aqueous synthetic route. The influence of various experimental variables, including introduction of chloride ions, amount of mercaptopropanoic a…
In this work,we report a method to improve the efficiency of the micromechanical cleavage technique to obtain few-layers graphene samples, from natural graphite flakes, which were previously submitted to two chemical treatment times with H2SO4(17 and 25 hours). After the chemical treatment times, Raman spectroscopy re…
Methods to control the dispersion of gold in supported heterogeneous catalysts are very valuable due to the strong nanoparticle size dependence on their activity and selectivity towards many reactions. Additionally, the ability to disperse large, inactive gold nanoparticles to smaller nanoparticles provides an opportu…
Aligned CoF2 nanochannel layers have been formed by self-ordering electrochemical anodization. In voltammograms these layers provide multiple oxidation states, an almost ideal rectangular pseudocapacitive behavior, a high specific capacitance and good capacitance retention. These layers may thus be promising for super…
The tuning of epoxide opening in GPTMS films allows for smart tailoring of the surface chemistry.
A novel solvent-free route is developed to synthesize a series of highly ordered mesoporous carbons (OMCs) and functionalized OMCs from solid raw materials.
A new phase of CsHgBr <sub>3</sub> with a noncentrosymmetric crystalline structure is synthesised and shows high laser damage threshold and nonlinear optical properties.
The recent contributions on changes induced by high magnetic fields in transport phenomena, such as convection, solute diffusion, solute or phase migration in the liquid, are reviewed and analyzed. Selectivity provided by the Lorentz, thermoelectromagnetic (a special kind of Lorentz force), and magnetic forces or comb…
The expansion of modern engines would have been unfeasible without advanced lubricant chemistry and proper lubricant formulation. Introduction of diamond like carbon (DLC) coatings opens further possibilities in improving performance of engine and transmission components, which cannot longer be achieved only by lubric…
1D–2D SiC <sub>NWs</sub> –GNPs hybrid nanofillers could make epoxy composites not only excellent thermal conductors but also aid them in retaining high electrical insulation.
A simple, fast, and cost‐effective method was developed in this paper for the high‐throughput fabrication of nanohole arrays on silicon (Si), which is utilized for antireflection. Wafer‐scale polystyrene (PS) monolayer colloidal crystal was developed as templates by spin‐coating method. Metallic shadow mask was prepar…
