Abstract
Chicory or the so-called in Egypt Al-serees is found in a large quantities of agricultural clover and vegetables. The present study investigates the methanolic extract 70% of Cichorium intybus L belonging to family Asteraceae. Data obtained from the elemental analysis revealed the presence of 23 elements. The major detected elements are Sodium) Na( 159.59 ppm, potassium )K( 19.29 ppm, Calcium )Ca( 8.68 ppm, Magnesium) Mg( 6.88 ppm and Aluminium )Al( 3.11ppm respectively. The metallic nanoparticles are traditionally synthesized by wet chemical techniques with potassium chloride. The formation of potassium chloride nanoparticles was confirmed by X-Ray Diffraction, (XRD). The XRD pattern indicates that the nanoparticles had cubic structure. The XRD analysis of potassium chloride (KCl) nanoparticles have five peaks at 28.39, 40.58, 50.25, 58.75 and 66.47 angles. At 28.39 = 2θ, the curve has the extra highest peak. The average crystallite size for KCl as observed from XRD spectral analysis was found to be 20 nm, which is in agreement with the Transmission Electron Microscpe (TEM) analysis. The Scanning Electron Microscope (SEM) analysis shows the spheric potassium chloride and other minerals nanoparticles.The potassium chloride and other elements nanoparticles may be used to improve the performance of photovoltaic solar cell. The selection of chicory (Al-serees ) is due to a cost effective and environmental friendly technique
Chicory or so-called in our country Egypt Al-serees, is found in a large number of agricultural clover and vegetable as shown in Fig.1. Although the plant is not in the cultivation of Alfalfa because it takes place from Alfalfa, and the farmer wants Alfalfa widely to fatten the cattle. The Chicory has medical benefits[1]. Large Serees is useful for patients with liver disease, diabetes mellitus and diarhea. Also, Al-seris is useful for kidneys as it burns fat and is used for slimming and its fiber is beneficial for the colon [2]. It is most likely known by the Egyptians as a medicinal plant [3] and used as a vegetable crop by ancient Greeks and the Romans [4]. Chicory (C. intybus L.) belongs to the family Asteraceae, a very large family with approximately 23,000 species subdivided into 1,535 genera grouped into three subfamilies: Barnadesioideae, Cichorioideae, and Asteroideae [5]. Chicory root has a .levels. This activity is attributed to high amounts of the inulin-type fructans that slow down carbohydrate digestion and glucose absorption in the gastrointestinal tract [6]. Chicory plants also produce a variety of other bioactive secondary metabolites, including caffeoylquinic acids and caffeic acid derivatives as major phenolic constituents [7]. Chicory is a perennial herb in the Asteraceae (Compositae) family edible as a vegetable crop and animal forage [8,9]. Contemporary applications for chicory leaves include salad, whereas root grounds are added to flavor coffee [8,10]. Inulin content has also made chicory root a common soluble fiber additive in the food industry [11,12]. The aim of the present study is to prepare a nanofluid using in Photovoltic solar cell cooling.
2. MATERIALS AND METHODS
This study was conducted at Environmental Studies and Research Institute –University of Sadat City - Sadat City - Menoufia-Egypt
2.1 Nanofluid Extraction from Chicory
This part includes chicory preparation to be used as diluted Nanofluid solution in the PV cooling system. Four methods were chosen for testing extracted ash properties. These four methods are chemical analyses carried out by Inductive Coupled Plasma-Mass Spectra (ICP-MS), That is a powerful tool for analyzing trace metals in environmental samples. A large range of elements can be detected using an ICP-MS. The benefits of using plasma compared to other ionization methods, such as flame ionization, are that ionization occurs in a chemically inert environment, preventing oxide formation, and ionization is more complete. Also, the temperature profile of the torch is relatively uniform, reducing self absorption effects. The process can be broken down to four stages; sample introduction, ICP-MS [13], the samples described below were tested in environmental and food biotechnology laboratory by using NIST traceable reference equipment and materials (Merck KgaA, ICP Multi-Elements Standard Solution IV, LOT # HC379062) in accordance with ISO/IEC 17025:2005 requirements and the methods referenced below meet ISO/IEC 17025:2005 and accreditation requirements, Sadat University, Egypt.
The mineralogical composition investigated by using X-Ray Difractometer (XRD) Bruker D2 Phaser 2nd Gen, Generator Current (mA) 10 m, Wavelength Alpha 1.54060 A°, start angle 10 andend angle 70, crystal size is calculated by scherrer equation [14,15]. The samples described below were tested in environmental geology testing laboratory by using NIST traceable reference equipment and materials in accordance with ISO/IEC 17025:2017 requirements and the methods referenced below meet ISO/IEC 17025:2017 and accreditation requirements, Sadat University, Egypt Scanning Electron Microscope (SEM) analysis. The specimens were examined with a JEOL/EO-JSM-6510 LV scanning electron microscope (Jeol JEM-2100 Scanning Electron Microscope) at Electron Microscpe,Mansoura University, Egypt and Transmission Electron Microscpe (TEM) analysis, Perfusion or immersion fixation of the tissue using a modified solution [16]: 2.5 % buffered glutaraldehyde + 2 % paraformaldehyde in 0.1 M sodium phosphate buffer pH 7.4, leave tissue overnight at 4°C , wash 3 x 15 minutes (min.) in 0.1 M sodium phosphate buffer + 0.1 M Sucrose , postfix 90 min. in 2 % sodium phosphate buffered osmium tetroxide pH 7.4 , wash 3 x 15 min in 0.1 M sodium p, after drying for ~15 min sections may be investigated using a transmission electron microscope . Ultrathin sections were observed at 160 kV using a JEOL JEM -2100 at Electron Microscpe Unit, Mansoura University, Egypt.
2.1.1 Collection of fresh chicory
Fresh chicory plant used in the study was collected from Nile Delta Clay soil in Menouf, Menoufia, Egypt. Then dried according to the standard condition (under shade at low humidity at room temperature). Fresh chicory were identified and authenticated by Dr. Mohamed Azzazy, Environmental Studies and Researches Institute, University of Sadat City, Egypt.
2.1.2 Preparation of chicory extract
To prepare the chicory extract, the plant was shade-dried completely, ground to powder
The Chicory powder was drenched in ethanol with concentration of 70% [17]. The Chicory alcohol mixture was left for 7 days in a glass jar before its filtration using. Figure 3 shows the soaked chicory. Then the solvent was passed through a Whatman paper filter to a flask. After that the solvent was vaporized slowly, and the high-density liquid extract was put in the Petri dish and dried at room temperature. Figure 4 shows the chicory extract in Petri dish. We put high-density chicory extract liquid in a muffle furnace at 450o C to convert it to ash. Figure 5 shows the chicory extract ash.
The used nanofluid also was made with the desired specs. To prepare the Nanofluid, water was mixed with the required mass grinded solid material, i.e. nanoparticles, to attain the required concentration (i.e. 0.01% or above by weight). The main advantages of Nanofluids are greater thermal conductivity and somewhat greater heat capacity [18]. Nanofluids have intensified thermophysical properties, such as thermal conductivity, viscosity and convective heat transfer coefficients, compared with conventional fluids [19].
Elemental composition analysis revealed presence of 23 elements, the major elements are Na 159.59 ppm, K 19.29 ppm, Ca 8.68 ppm, Mg 6.88 ppm and Al 3.11ppm. Table.1 shows the result obtained from the elements’ analysis that was carried out on the chicory extract.
