“…A transmission electron microscopy (TEM) and UV-vis spectrophotometer was used to measure the solution's absorption spectrum at 420 nm, which resulted in the confirmation of the nanoparticles production. The particle size was determined using a Hitachi H7100 transmission electron microscopy (TEM) [40][41][42][43] and (UTHSCSghA Image Tool) version 3.00 application to calculate the distributions [44][45][46].…”

The present study demonstrates a green process for the synthesis of spherical-shaped and stabilized silver nanoparticles Ag NPs using gamma irradiated conditions. This method has certain advantages over conventional methods since it can manage the particle size and structure and generates totally reduced and extremely pure nanoparticles free from by-products or chemical reducing agents. Silver nanoparticles composite (Ag NPs / CM) is prepared from an aqueous solution of silver nitrate, chitosan and isopropanol, at room temperature using gamma irradiation doses to induce reduction and cross-linking to formation in situ Ag NPs/ CM-chitosan-isopropanol solutions. The production and homogenous distribution of silver nanoparticles in the hydrogel matrix were characterized using transmission electron microscopy, XRD, Zeta potential and UV-Vis spectrophotometer analysis. The silver/ CM-chitosan-isopropanol matrixes possessed different gamma doses using a Co- 60 gamma source. Through the comprehensive results of IR- Ag NPs /(CM- chitosan isopropanol solutions due to antibacterial activity test, the results show the prepared Ag NPs /CM-chitosan-isopropanol could be used as an antibacterial agent. The obtained Ag nanoparticles were stable for over 3 months at room temperature. the analysis outcomes indicate that the colloidal Solution (silver nanoparticles / (CM chitosan - isopropanol)) has a promising ability to be used in antibacterial applications in the future.

High-efficiency radar wave absorbing material was prepared utilizing nanoparticles poly (glycerol /phthalic anhydride), and the effect of using these nanocomposites with thermal paint on the properties of electromagnetic absorbing was analyzed and investigated. Results show that when the percentage of nano polymers is increased from 1% to 3%, with the presence of 2.5% of iron oxide, the reflectivity loss value rises dramatically. For the reflectivity up to 27.2dB at a frequency of 8.3 GH and a bandwidth of (8.1-8.2GH), there is a clear attenuation of the radar waves, which is confined within a bandwidth of GH (9-9.3GH). This material can be utilized as a high- efficiency radar wave absorbing applications.

The designer does an important role in using and developing these aspects because of their role in consumer decision to buy or not [14]- [16]. Woods have been used for many decades in furniture manufacturing [17]- [19].…”

Particleboard is a good substitute for costly wood/plywood boards. Particleboard can be developed from Date-Palm Leaves (DPL) as an annually renewable agro waste. DPL has a higher ultimate fiber length (1.25-2.50 mm) and higher α-cellulose content (about 60%) than hardwood/plywood and jute stick. In this present research, a numerical analysis focused on predicting the optimum strength for a selected chair style based on the mechanical strength behavior of the date palm leaves particleboard. This analysis is based on employing a chair model generated by Solidworks software and simulated by ANSYS software using the experimental mechanical properties of the selected material. Results show that the numerical analysis can predict a precise strength and safe behaviour for the selected chair shape and size according to the material properties without the manufacturing process taking part.
