The effect of different light spectra on beta-carotene production by Dunaliella salina

Iranian Journal of Chemistry & Chemical Engineering-international English Edition (2020)

Monnire Moslemipetroudi Farshid Pajoum Shariati Hossein Delavari Amrei Amir Heydari Nasab

This study focused on the effect of different light intensities and spectra on the beta-carotene production within Dunaliella salina cells (green eukaryote microalgae) which are purified from Urmia Lake in the northwest of Iran. For this purpose, four LED light spectra (white light: 360–760 nm, red light: 620–645 nm, yellow light: 587–595 nm, blue light: 460–475 nm) were used in this experimental research. The light intensity of 200 µmol/(m2 s) was considered for each the LED light spectra. The highest beta-carotene content extracted under a sequential combination of colored light (white, blue, red and yellow respectively) was 16.93 µg of beta-carotene per mg of cell dry weight and the highest accumulated beta-carotene within the cells among single-colored light was 15.16 µg /mg when the cells were cultivated under yellow light.

The Effect of Instantaneous and Slow Release Salt Stress Methods on Beta-carotene Production within Dunaliella Salina Cells

Iranian Journal of Chemistry & Chemical Engineering-international English Edition (2020)

Farshid Pajoum Shariati Hossein Delavari Amrei Amir Heydari Nasab Ali Hashemi

The main concept of the present study is taken from the growth pattern of Dunaliella salina (green unicellular eukaryote microalgae) in Urmia Lake which is the second biggest saline lake in the world. In this study, different models of salt stress, including instantaneous (1 and 2 M) and consecutive slow-release salt stresses (0.5 M) were tested, and the amount of beta-carotene for each test was evaluated. According to the results, the highest amount of beta-carotene was obtained by the slow release method of salt injection with the amount of 9.01 µg of beta-carotene per mg of the dry weight of microalgae. The largest amount of beta-carotene production in 1 and 2 M instantaneous salt stresses method were recorded as 4.35 and 0.65 µg mg-1 respectively which were up to 2 and 14 times lower than the highest beta-carotene production under slow-release salt stress method.

Doxorubicin Loaded Liposomal Nanoparticles Containing Quantum Dot for Treatment of Breast Cancer

Iranian Journal of Chemistry & Chemical Engineering-international English Edition (2019)

Javad Shahabi Azim Akbarzadeh Amir Heydari Nasab Mehdi Ardjmand

In addition to increasing the efficacy of various drugs, Nanoparticles reduce their side effects. In this study, different nanoparticle formulations of Doxorubicin anticancer drugs were prepared. The efficacy of the formulations produced in the cell culture medium was studied compared with the free drug. Reverse phase evaporation was used to form the liposome containing doxorubicin. The graphite nanoparticles were prepared. These nanoparticles were mixed with the liposome containing doxorubicin, and the related Nano-complex was conjugated. Spectroscopy methods for visible light-ultraviolet, light and light dynamics differentiation were used to describe nanoparticles. For the toxicity of different formulation, MTT and MCF-7 cells were used. The amount of drug loading in the liposomes was 72%. The largest amount was related to the Nano-conjugated complex and the smallest size was related to the graphene-oxide nanoparticle with a nanometer size. The controlled release in 96 hours and the amount of drug release was 95.43%. Doxorubicin-containing liposome toxicity was 75% and Nano- conjugated complex was 85%, at the lowest drug concentration (10µM). The free drug created 35% cell toxicity in 10µM and 89% in 2500µM. The results of the study showed Liposomes act as a suitable nanoparticle for doxorubicin. It was found that the effect of nanoparticles of graphene oxide is very important. In the presence of this nanoparticle in the complex, toxicity increased significantly.

The Effect of Nanoparticles on the Mass Transfer in Liquid–Liquid Extraction

Chemical Engineering Communications (2014)

Asghar Mirzazadeh Ghanadi Amir Heydari Nasab Dariush Bastani Ali Akbar Seife Kordi

This article investigates the effect of nanoparticles on mass transfer in the liquid–liquid extraction for the chemical system of n-butanol–succinic acid–water. For this purpose, nanofluids containing various concentrations of ZnO, carbon nanotubes (CNT), and TiO2 nanoparticles in water, as base fluid, were prepared. To examine the flow mode effect on mass transfer rate, different fluid modes including dropping and jetting were employed in the process. Results show that mass transfer rate enhancement depends on the kinds and the concentration of nanoparticles and the modes of flow. It was observed that after adding nanoparticles, the mass transfer rate significantly increases up to two-fold for ZnO nanoparticles. Furthermore, the results indicate that under the circumstances in which the mass flow rate is high enough, the effect of nanoparticles on the mass transfer phenomenon is too slight.

EFFECT OF TEMPERATURE, TIME AND VOLUME OF SOLVENT USED IN EXTRACTION SALMON LIVER OIL

Fatemeh Zare Kazem Abadi Aboalhasan Alavi Amir Heydari Nasab

Salomon liver oil is an accessible and easy source of long-chain polyunsaturated fatty acids (PUFAs). These fatty acids play critical role in human health and have significant impacts on prevention from cardiovascular diseases, hypertension, etc. salmon liver oil, as one of the valuable fish residuals, is used in this work for extraction of oil. Current study firstly was done using Soxhlet system due to solvent method, and normal hexane solution was utilized for oil extraction, and the effect of temperature, time and volume of solvent used parameters to extract the amount of oil extracted from salmon liver was examined. Oil extraction process was conducted in temperatures 50, 60, and 68 °C in times 1, 2, 3, and 4 hours. Changes in volume of solvent (150, 200, and 250 ml) were investigated in optimal time and temperature conditions. Finally, direct impact of time and temperature increase, and in a lower degree, direct impact of solvent volume increase on increased amount of oil extracted from salmon liver was specified. Optimal parameters for achieving highest amount of salmon liver oil extraction were temperature 68 °C and 4 hours with solvent volume of 150 ml. Maximum oil extracted under this condition was 2.9711 g from 5 g of original sample (powder of salmon liver).

Synthesis and optimization of Cu_xNi_0.6-xMn_0.4Fe₂O₄ oxygen carrier for chemical looping steam methane reforming

Energy Sources Part A Recovery Utilization and Environmental Effects (2021)

Mousa Nazari Amir Heydari Nasab Mohammad Soltanieh Bozorgmehr Maddah

The self-supported CuxNi0.6-xMn0.4Fe2O4 oxygen carrier (x = 0.1–0.5) is synthesized to be applied in the chemical looping steam methane reforming (CL-SMR) process through the synthesized co-precipitation method. The response surface methodology (RSM) based on the Box–Behnken model is adopted to evaluate the effects of independent variables on the functionality of responses as well as predicting the best response volume. In this method, the variables consisting of reaction temperature (550–700°C), oxygen carrier (OC) loading percentage (0.1–0.5), steam-to-CH4 ratio (S/C), (1.5–3.5), and redox cycles’ count (10–24) and the responses consisting of hydrogen (H2) production yield, CH4 conversion percentage, and CO/CO2 molar ratio are assessed. The analysis of variance (ANOVA) results indicate that the temperature reaction and the OC type are the most effective parameter, while the redox cycles’ count has the least effect on CH4 conversion percentage and produced H2 yield. The obtained optimization results in the laboratory conditions indicate that the self-supported Cu0.3Ni0.3Mn0.4Fe2O4 OC in the operational conditions of 650°C, S/C = 2.5, and redox cycle = 24 are the best responses for H2 production yield, CH4 conversion percentage, and CO/CO2 molar ratio with 80.9, 99.6, and 9.7, respectively. The material structure and the functional groups are assessed through X-ray diffraction pattern (XRD) and Fourier transform infrared spectroscopy (FT-IR) respectively. The morphology and particles’ size are analyzed through FESEM through EDX whereas the OC-specific surface area analyses are carried out by BET.
