The use of fermenters at large scale is usually hampered by sub-optimal conditions in terms of yield and productivity, along with the low tolerance of strains to process stresses, such as substrate and product toxicity, and other fermentation inhibitors. Attempts to improve the industrial efficacy of fermenters have been in the areas of genetic engineering […]
ETI Aluminyum A.Ş., the primary aluminium manufacturer of Turkey, is also one of the major integrated plants of the world capable of performing production from mining until end product. The alumina refinery was designed on a certain boehmitic bauxite quality basis. However, bauxite properties have changed over the years, resulting in the urgent need for […]
One of the serious problems in polybutadiene rubber (PBR) production units is the color change in products, which is due to aging and the inability of antioxidants to protect the product, especially at high temperatures. In this study, the effects of amine-type antioxidant [octylated diphenylamine (OD)] and non-amine-type antioxidant (Irganox 1520) on the color yellowness, […]
The corrosion and corrosion inhibition of Pb and Pb–In alloys in HCl solution, were investigated. The study was performed in the absence and presence of the phytic acid (PA) inhibitor using potentiodynamic polarization and electrochemical impedance spectroscopy measurements, and complementary by scanning electron microscope (SEM) and X-ray spectroscopy analysis (EDX) investigations. The obtained outcomes showed […]
Inhibition action of seroquel on corrosion of zinc in 0.1 M HCl solution was investigated using weight loss, electrochemical potentiodynamic polarization and impedance spectroscopic techniques. Corrosion inhibition efficiency showed the positive effect with increase in concentration of inhibitor and with the increase in temperature. Results obtained from all the methods are in good agreement with […]
High-end applications require a very tall vertical extraction column in some cases which deteriorates protection against radiation and cannot be employed for indoor applications. On the other hand, horizontal extraction columns offer higher efficiency and pretension, but lower maximum throughput. In order to address this issue, the L-shaped pulsed extraction column is a new type […]
Bamboo-based multilayer composite materials are a new type of bio-composite material with high strength, wide applicability, and low cost. Based on the life cycle assessment (LCA) method, this paper analyzes the energy consumption and harmful substance emissions of producing 1m3 of this product using the basic data inventory provided by the material processing enterprises, GaBi […]
By nthesizing nano zinc oxide with different morphologies, such as spherical, snowflake like, and starfish like, and utilizing its unique physical and chemical properties, combined with the cavitation effect of ultrasound, it is expected to achieve effective degradation of dye wastewater. In the comparative experiment of using nano zinc oxide, ultrasound, ultrasound+nano zinc oxide to […]
Removal of metals from wastewaters causes a big concern from the environmental point of view due to their extreme toxicity towards aquatic life and humans. Application of As(III) from aqueous solution by ZnO nanorods as adsorbent has been investigated in the present study. The synthesized nanorods were characterized by XRD, FT-IR spectroscopy, SEM, and thermogravimetric […]
Objective: To investigate the effect of sevoflurane postconditioning on the levels of Nrf2 expressed in the early stage of hepatic ischemia-reperfusion injury (HIRI) in rats and to explore the possible Mechanism of sevoflurane postconditioning in attenuating HIRI. Methods: 24 S.D. rats were randomly divided into Sham group, Sevoflurane group, HIRI group, and HIRI+Sevoflurane group. The […]
