For the preparation of the coating the CNTs were dispersed in a 30 wt% solution of 3MBP-dca in deionised water by sonication. The resulting black slurry was filtered by vacuum filtration and the black residue in the filter was washed with 50 mL of ethanol to remove excess IL. The residue was subsequently placed in ceramic crucible and thermally treated in a furnace under constant argon flow to ...

(28 mg, 24 µmol) was dissolved in a mixture of ethanol (2 mL) and water (1 mL). Pd/C 10% (12 mg) was added and the solution was stirred. Vacuum and H 2 were alternated and the mixture was allowed to stir under H 2 overnight. The mixture was filtered off through Celite and concentrated. The residue was dissolved in water and filtered through a 0.45 µm syringe filter and concentrated. The residue...

Vacuum distillation may be used to enhance the separation of hydrocarbons because of the improvement in relative volatility at the lower pressure. Vacuum may also be employed to break azeotropes by using two columns in series that operate at different pressures. And, it may be required to reduce the boiling point of the bottom composition so conventional heat-transfer fluids can be used for hea...

Masses and decay constants of the scalar quarkonia, Q0ðQ 1⁄4 b; cÞ with quantum numbers IGðJPCÞ 1⁄4 0þð0þþÞ, are calculated in the framework of the QCD sum rules approach both in vacuum and finite temperature. The masses and decay constants remain unchanged up to T ’ 100 MeV but they start to diminish with increasing the temperature after this point. Near the critical or deconfinement temperatu...

MSWI fly ash is susceptible to contain high amount of polychlorinated dibenzo-dioxins and polychlorinated dibenzo-furans. However, the use of MSWI residue for road construction started in France at a period when MSWI Bottom Ash and MSWI fly ash were not separated. From four old road sites, MSWI residue, road soils, reference soils and geo-textiles were sampled and their PCDD/F contents were ana...

Using radio frequency sputtering, CaTiO3 layers with varying thicknesses and deposition temperatures are deposited on different bottom electrodes. On elevated temperatures, the CaTiO3 layer growth and therefore the properties like crystallinity and leakage current depend strongly on the morphology and lattice constant of the bottom layer. With the use of temperature stable bottom electrodes, wh...

We discuss a mechanism to generate hierarchy between masses of the top and bottom quarks without fine-tuning of the Yukawa coupling constants. In the framework of the two-Higgs-doublet model (THDM) with a discrete Z2 symmetry, there exists the vacuum where only the top quark receives the mass of the order of the electroweak symmetry breaking scale v(≃ 246GeV), while the bottom quark remains mas...

An ultrasonic treatment was applied to the vacuum gas oil at intervals of 5 30 minutes, 70°C. In this work, improvement important properties Iraqi oil, such as carbon residue, studied with several parameter conditions that affect efficiency, sonication time (5, 10, 15, 20, 25, and 30) min, power amplitude (10–50%). After treatment, residue evaluated using a Conradson meter (ASTM D189). The expe...
