Compared to iron and steel, aluminum alloys have the advantages of lower density, higher specific strength and superior corrosion resistance. Therefore, lightweight aluminum alloys are being considered for use in aircraft, automobiles, railroad cars, and ships. In this study we are going to protect a specific Aluminum alloy which is used in marine industries such as submarines against corrosion. Thus, early studies on the corrosion behaviour of this alloy in two different seawater solutions (x, y) was carried out to find how to protect it according to the results of previous
studies conducted by researchers. Pitting is the main part of the corrosion of this alloy in marine environments and we are going to minimize this type of corrosion.

Magnetic train as one of the IYPT 2016 problems contains a battery with two attached permanent magnets in both ends of it; when put in solenoid it moves. Why this train moves and relevant parameters have been studied to find its best efficiency and the effect of some relevant parameters on speed and power with considering electromagnetic laws. Using simulation and formulas help to study more on magnetic fields in the whole train.

The current craze of water bottle flipping involves launching a partially filled plastic bottle into the air so that it performs a somersault before landing on a horizontal surface in a stable, upright position. Investigate the phenomenon and determine the parameters that will result in a successful flip. The secret behind a success flip of a water bottle into the air, is the distribution of mass, decreasing the angular velocity and finally landing like a shuttle cock, in this way for solving the problem easier we
divided the hole system to 3 phases: Damping, Landing and Impact.

When a ring is put on a horizontal cylindrical shaft, it start to rotate around its axis at constant speed. It can travel along the shaft in either direction depending on the tilt of the ring. In this article we are going to investigate this phenomenon which was presented in IYPT 2018. We are going to investigate the phenomenon in a case were the ring is made of cardboard and the shaft is oiled. The reason behind the motion at the first place regarding to the microscopic point of view is explained that the motion of the shaft is intrinsic of the shaft and the rings circular shape. A
mathematical model is used to clarify this phenomenon accurately.

Quark cottage cheese and similar varieties of white acid-set cheese can be produced from milk. In this research as one of the International Young
Naturalists’ Tournament, IYNT 2018 problems, this process has been
investigated experimentally and the properties of the resulting product were studied too.

Open a random Wikipedia article and click on the first link in the article. Keep clicking on the first link of each following article. It is argued that you will quickly end up on the page Philosophy. This is one of the IYNT 2018 problems which is investigated whether this is true and how we can describe such an observation.

A simple air horn can be constructed by stretching a balloon over the opening of a small container or cup with a tube through the other end. Blowing through a small hole in the side of the container can produce a sound. The relevant parameters which affect the sound have been investigated in this research as one of the problems in IYPT 2017.
