Investigations were carried out to compare the effectiveness of compounds such as sodium nitrite, trisodium citrate (TSC) and TSC–zinc acetate to inhibit the corrosion of steel rebar in simulated concrete interstitial solution contaminated with chloride and to explain the mechanism of corrosion inhibition on reinforcing steel by these systems. Inhibition efficiency of these systems was […]
The current study was designed to give more knowledge and helping to exploit the leaves of the plants L. stoechas collected in Tlemcen region in the west of Algeria by determining the anti-corrosive activity of its essential oil. The inhibitory efficiency of the essential oil of the plant obtained by hydrodistillation and characterized by GC […]
Simple methods for immobilizing titania into pumice were applied, where the products had been used for the application of photodegrading phenol waste. There were two simple methods, which were used separately: solvent evaporation and dip coating. Based on titania sol stability test, it was observed that acid condition would be favourable for immobilizing titania unto […]
This work reports the synthesis of nanocomposites of Fe3O4–TiO2–Ag with different weight concentrations of iron (Fe) and silver (Ag) doped on TiO2. The nanocomposites were prepared by a novel and facile ultrasonic-assisted hydrothermal method, and their effectiveness was evaluated for photocatalytic degradation. X-ray diffraction, scanning electron microscopy, Fourier transform infrared spectroscopy, and N2 adsorption–desorption methods […]
Homo- and copolymers of 2-(N-phthalimido)ethyl methacrylate (NPEMA) and p-chlorophenyl methacrylate (PCPMA) were prepared in N,N-dimethyl formamide (DMF) solution at 70 °C using 2,2-azo-bisisobutyronitrile (AIBN) as initiator. The nano-CdS-doped polymer composite of NPEMA and PCPMA was prepared via in situ technique. The homo- and copolymers of NPEMA and PCPMA were characterized using FT-IR spectroscopy and gel permeation […]
Thermal and catalytic pyrolysis of individual plastics such as polypropylene (PP), low-density polyethylene (LDPE), high-density polyethylene (HDPE), and mixture of all three plastics (PP + LDPE + HDPE) were carried out in the presence of calcium bentonite as catalyst in a batch reactor to obtain suitable liquid fuel. The dependencies of process temperature, effect of catalyst, feed composition on […]
Four types of the multi composite membranes were fabricated to decrease the sulfur content in diesel fuel, which the investigated polymers are polydimethylsiloxane (PDMS), polyethyleneglycol (PEG), polyethersulfonic (PES) and cross-linked polyacrylonitrile (PAN) with tetra-ethyl-ortho-silicate (TEOS). The effects of the operating parameters such as the cross-linking temperature (65–85 °C) and cross-linking time (0.5–2.5 h) were studied on the […]
The corrosion inhibition property of electrochemically synthesized 2,2′-disulfanediyldianiline compound was investigated for mild steel in 1 M HCl using electrochemical and weight loss techniques. The morphology of steel surface was examined using SEM and optical microscopy. Thermodynamic parameters were determined and discussed. To study the effect of the molecular structure of inhibitor on its inhibitive […]
