In past decades, polymeric micropillar devices have gained a great deal of attention in micro and nano technology research as the result of their potential and practical usage in many applications. This project is going to deal with the process of how to fabricate the magnetic micropillars, from the beginning – the planning and design, improving the existing process, lithography to create the base silicon mold and then creating the PDMS pillars that contains nano magnetic particles of Fe_3 O_4, the process today is not efficient enough in terms of cost and time and we are wishing to improve it, in the end we will have a device with micro-pillars that can move correspondingly to external magnetic field which will help us to do many advanced experiments in the biology field like using the device for cell stimulation.

In our company, the CI/CD processes are very long (over 2 hours). Since this is a blocking step in the release flow it causes holdups of our fast-paced releases. Eventually, we are getting a backlog of unreleased features, which could be mitigated by releasing many things at once, but that comes with additional risks.

Aluminum is common material used in the welding industry due to its suitable properties, Although aluminum welding generally has disadvantages. One of these weaknesses is the formation of porosity, which will affect the welded joint's mechanical properties. porosity is formed due to two mechanisms, shrinkage porosity caused by shrinkage during the metal solidification process and gas porosity caused by air trapping and undissolved hydrogen. The welding process often produces gases such as hydrogen, carbon dioxide and steam. During welding, the metal goes into a liquid state and then cools at a rapid rate. because In a liquid there is a higher solubility of a gas than in a solid, This may trap gases inside the material and create bubbles when the welding takes place. n order to minimize the problems with the porosity of the material due to welding, it is necessary to control the speed of the process, thermal gradient, dynamics of melt pool flow and solidification. Therefore, in order to solve this problem, we use laser beam welding.

This project aims to find better ways for solar energy harvesting, storage and usage - in a non electric ways, which will offer more versatile usable energy.

Solar power plants based on concentrated solar power technology use heat energy to heat water into steam and drive turbines. One of the challenges facing the engineers of those stations is that usually the hours of high electricity consumption are at night after the workers return to their homes and at that time there is no sun and no electricity is generated. In order to utilize solar energy during the day even during the night, the energy needs to be stored, for the purpose of storing energy excess energy is used during the day for the purpose of melting salts with a high heat capacity and thus storing the heat energy in them. The salt tanks and the pipes through which they Tow are made of L316 Stainless steel and are exposed to corrosion due to the exposure to the salts and this causes irreversible failures in the line.
