- Item3D printing with special materials(2025-07-07) Saleh Amer; Mohammad Odeh; Mohammad Sabra Abstract This This project explores the use of 3D printing with special materials, focusing on thermoplastic polyurethane (TPU) mixed with a foaming agent. These materials are known for being flexible and lightweight, and their properties can be adjusted by changing the printing temperature, flow, and speed. Our goal was to understand how to get the best possible print quality and mechanical performance from them. To improve the printing process, we added a closed chamber around the 3D printer to control the surrounding temperature. We built a heating system using a heater, fan, thermistor, and Arduino-controlled PID system, which helped keep the temperature stable during printing. We also experimented with different settings — like nozzle temperature, flow, speed and layer height, to see how they affect the final part’s quality. A series of test samples were printed using design of experiment method, and we evaluated how the internal structure and porosity were affected. To measure the strength of the printed parts, we assembled a universal testing machine to perform compression tests and better understand how the materials respond under pressure. We also partnered with SESAME (a scientific research center in Jordan) to scan samples using micro-CT imaging, giving us a clear picture of the internal foam structure. Overall, this project shows how environmental control, parameter tuning, and custom testing can lead to better, lighter, and more reliable 3D printed parts — especially for industries that need flexible or energy-absorbing components like automotive, medical, or wearable devices.
- ItemTablet disintegration device r(2025-07-07) Yazan Altawil; Anas Shaar; AbdalQader SharifProject’s Abstract: Tablet Disintegration Device is ensuring the effectiveness of tablets by measuring their disintegration behavior and time. The disintegration time of a tablet is a key indicator of its ability to deliver the active pharmaceutical ingredient to the body effectively. If tablets disintegrate too slowly, A significant amount of the drug may be excreted in the feces without being absorbed; if too quickly, the blood level may become too high, causing an overactive response. The project will include the mechanical design of the device as well as accurately simulating the human digestive system, Integration of sensors and control systems to monitor and measure the disintegration process in real-time, Finally Ensure that the device meets industry standards and is calibrated to perform tests accurately and consistently. The project aims to design and develop a mechanical device that simulates the human environment (stomach) in which tablets are disintegrated and is easy to use for medical laboratory technicians. The device consists of: a Media Reserviors, a pump that pushes the liquid into the flow cell and a flow cell where the tablets are placed. The cell contains a Heat Exchanger Coil. The tablet is placed inside the flow cell and once the liquid is pumped from the reservoir through this cell it comes in contact with the tablet and the tablet starts to disintegrate. The flow cell contains a heat exchanger coil which helps in maintaining the temperature of the liquid equal body temperature, Samples of the liquid in the tank can be collected manually (Manual Sampling)or automatically using an another pump (Automated Sampling) Similar devices and applications have been developed for this device such as: ZT 720 Series. However, this project aims to create a more effective solution in terms of accuracy and ease of use.

The spread of which is rapidly increasing, making the search for new treatment strategies extremely important. The project aims to establish a center for behavioral and automated in vivo testing using specialized equipment at a lower cost, which will contribute to accelerating the development of new and effective treatments for these complex diseases. There are several important aspects to cover in the project including: Proper mechanical design for reliable behavioral tests, integration of high-precision sensors to collect data accurately, automation to reduce human error, and cost-effective development are essential to make the devices widely available, and collaboration between pharmacy and mechatronics will ensure that the devices meet the requirements of clinical research. The main goal of the collaboration is to develop low-cost robotic devices for behavioral models of central nervous system diseases such as Alzheimer’s and Parkinson’s. The devices improve data performance through compact and compact sensors via graphics.

Several companies are offering preclinical testing applications, including Harvard Apparatus, Pan lab, and Med Associates, which provide automated and specialized equipment for testing animal behavior, memory, anxiety, and motor activity.
- ItemDesign and Optimization of a Hybrid Solar Photovoltaic/Diesel Energy System Using HOMER Software(2025-06-23) Abdullah Ammar; Hamza Aker; Hussam EzzatProject’s Abstract: Energy access in Palestine faces serious challenges due to political instability, high dependency on imported electricity, and limited local energy resources. The West Bank has an abundance of solar potential, but it is not yet entirely utilized. In order to provide a dependable, economical, and sustainable energy solution, this study explores the design and optimization of a hybrid solar photovoltaic (SPV) and diesel generator (DG) system for the Palestinian Museum in Ramallah. The objective is to use HOMER and PVsyst software to assess the hybrid system's technical, financial, and environmental feasibility. Based on real energy consumption data, sun irradiance, and system component specifications, these tools made simulation and performance analysis possible. In order to model a 230 kWp grid-connected PV system, 576 modules and inverters with a combined output of 220 kWac were used. The diesel generator was used in times of solar shortages because the PV system was not built with battery storage. It was also utilized when the grid was unavailable. The system can generate 364,653 kWh yearly, according to PVsyst results, with a performance ratio of 80.84%. Strong economic viability is demonstrated by the system's low levelized cost of energy (LCOE) of 0.0307 USD/kWh, 3.2-year payback period, and internal rate of return of 31.33%. In terms of the environment, the system lowers CO₂ emissions by about 394.7 tons per year. These results were confirmed by HOMER simulations, which found that the PV/Grid system had the lowest COE at 0.0835 USD/kWh, while the PV/40 kW DG hybrid system provided reduced emissions and increased reliability with an 83% solar energy ratio compared to diesel-only options. A renewable energy fraction of 84.8% was achieved by the hybrid arrangement, highlighting the financial and environmental benefits of greater solar integration. By offering an affordable and appropriate hybrid renewable system model, this study helps close the energy gaps in Palestine and promotes resilience, energy independence, and long-term sustainability in areas challenged by conflict and a lack of energy. Keywords: Solar photovoltaic, Hybrid system, HOMER, Solar Photo-Voltaic, Diesel Generator, Solar/Diesel hybrid energy, Palestine.
