“…The large and large peak around 1030 cm -1 belongs to M-O-M structures in inorganic structure and is a very characteristic peak. The small sharp peak around 3284 cm -1 belongs to the -OH stretch in the inorganic structure (Chen et al, 2010;Sim et al, 2012;Jayarambabu et al, 2014;Gawbah et al, 2017).…”

In this study, the oil of linden seeds collected from Malatya region was taken by solvent extraction method and their characterization was made. Seeds for experiments at the end of August 2018, linden seeds in Malatya region were collected and their outer shells were separated from the seeds and oil was obtained with a Soxhlet device. Acetone, hexane and ethyl alcohol were used as solvents in the Soxhlet device. In order to determine the oil quality of the obtained oils, XRD, SEM, elemental analysis, ash determination, saponification number were subjected to a number of analyzes. As a result of the analyzes made, the oil yield with acetone was 28% by weight, with hexane 28.65% and 33% ethyl alcohol values were determined. In the fatty acid composition of linden tree seeds, the values by weight were found to be oleic acid: 27,442 for acetone, 30,852 for hexane, 10,9545 for palmitic acid: acetone, 11,929 for hexane, 51,188 for linoleic acid: acetone, 44,145 for hexane. The soap number values are 176.72 for hexane in mg KOH/g oil; 246.94 for acetone; It was found as 232.48 for ethyl alcohol. Ash determination values average 5,575%; bark ash was found to be 2.1% differently.

“…There are challenges of using conventional heating vis-a-vis the laser-based combustion. Recently, reported the preparation of silica and silicon carbide from wheat roughage and sesame seed cake by Nd: YAG laser as the combustion source [3,4]. In addition, rice husk ash, which is rich in silica (92-97%), can be an economically feasible raw material to produce silica gel and powders [5].…”

The focus of this study was to develop a method to demonstrate the feasibility of obtaining useful and high-value resources from Phoenix dactylifera residues and, to determine the physical and chemical properties of the ash of dates-palm-tree remains. Date-palm leaves and fiber samples were combusted for 50 s, using an Nd: YAG laser with 40 W output power. It was found, that combustion of agricultural waste could be completed in 30 seconds by laser while it required 1-2 minutes by microwave and at least 2 hours for conventional heating. The subjects of this treatment, the leaves and fiber samples, before and after combustion were investigated by X-ray diffraction (XRD) and Fourier transform infrared (FTIR). The XRD results of the palm-fiber after combustion reveal that the samples were crystallized with a rhombohedral phase of acetamide and hatrurite, orthorhombic finite, and Ca4Si2O6 (CO3)(OH)2, and a monoclinic phase of ikaite properties. The XRD patterns of palm-leaf after combustion reveal that the samples were crystallized with orthorhombic hillebrandite, rhombohedral acetamide, and the monoclinic phase of each karpatite, morganite, and howlite. Finally, the FTIR exhibited several absorbance peaks, assigned to silica.

“…Its special properties, such as high mechanical strength, flexural resistance, make this ceramic material ideal for esthetic crowns, bridges, and frameworks in the anterior and posterior region (El-Ghany and Sherief, 2016). There have been numerous research studies the effect of laser matter irradiation; for example, laser milk pasteurization (Marouf and Sara, 2018;Amna and Marouf, 2018), solar cell surface modification (Marouf et al, 2014, Islam et al, 2020, bee honey irradiation (Al Humira and Marouf, 2017) and production of highly value materials from agricultural waste (Gawbah et al, 2017;Gawbah et al, 2018). There have been numerous research studies the interaction of lowlevel lasers with biological materials such as blood; for examples; studding of He-Ne laser effect on human whole blood (Haimid et al, 2019a), investigating the effect of He-Ne laser on human whole blood (Haimid et al, 2019b), and it also used to induce emission in human teeth to distinguish www.universepg.com l UniversePG between dental caries and sound teeth (Marouf and Khairallah, 2019).…”

Different parameters like irradiated area, irradiation time, laser wavelength, pulse energy, and the nature of the irradiated material determine largely the effect of the laser-matter interaction. In this, study the influence of high power Nd: YAG laser irradiation on the hardness and surface properties of zirconium silicate (ZrSiO4) ceramics was investigated. Specimens of zirconium ceramic pieces were divided into four samples depend on irradiation duration as follows: one reference sample and three samples treated with Nd: YAG laser at irradiation times vary from 3 to 5 minutes. The irradiation was done with 60 W output power. The hardness and tensile strength were determined and the optical properties were characterized by UV-vis spectroscopy, also EDX spectra were carried out. The obtained results revealed that high power (60 W) Nd: YAG laser provides higher hardness compared to the reference sample surface. Increasing irradiation time resulted in the higher hardness of the ceramic surfaces. EDX results showed that laser irradiation does not change the chemical surface composition of ceramics. Moreover, an increase in transmittance of the irradiated zirconium silicate in the visible and near-infrared range was also found using UV-vis spectroscopy.
