On 8/1/2018, a group of teachers of the Materials Engineering Department / University of Technology has been working on scientific research to participate in the Tmress Confrence Series, to be held in early February in Beirut, Lebanon. The title of the first research presented by Asst.Prof.Dr. Ala’a Alla al-Din (Characteristics of Thin Films of SnO2 Deposited by Thermal Chemical Spraying Using Different Salt Solutions). In this Paper, the thermal chemical spraying method was used with one atomizer and two nozzle (SN, DN). The thin tin oxide membranes were formed in different structures. The tin oxide membranes were prepared at a concentration of 0.005M and their thickness was about 0.2 - 0.002 μm. Microscopic examination of the membranes, in addition to optical transparency and to the contact angle. The results showed that the membranes were crystallized with a four-angular structure with tiny micro-structures from plates to columns and clusters resembling cast.
The second research presented by Asst.Prof.Assel Basem (Natural fiber recycling and use in green cement mortar) to the process of manufacturing environmentally friendly cement mortar consisting of natural waste (coconut fiber, banana fiber, papyrus fiber, and palm fiber). Various additives (0 - 0.25 - 0.50-0.75-1 g) Natural waste (plant fiber) was the partial replacement of cement, mechanical properties and thermal conductivity. It was found that the increase of additives from natural waste increases the strength of the pressure and the hardness of cement mortar and the lack of thermal conductivity properties and water absorption. a To take advantage of these wastes and recycling instead of burning them.
