The Development Of A Diffraction Grating For An Element Of Directional Output Of Radiation From Microlasers, Evgenii Levdik
The Development Of A Diffraction Grating For An Element Of Directional Output Of Radiation From Microlasers, Evgenii Levdik
The International Student Science Fair 2018
In nanophotonics, axisymmetric microlasers became widespread. As they have lots of advantages, they can be used in many scientific and industrial areas, such as microchips for data transfer in order to make electrical circuits smaller. But there is a drawback: they radiate in all directions in the plane of the substrate. This is why elements of directional output of radiation are being developed. A necessary part of such element is the diffraction grating applied to the surface of the waveguide. Such gratings are already being created, but with very expensive methods, for example, electronic lithography. We present a technique for …

Determining The Activation Energy Of Glucose Syrup Using The Arrhenius Equation, Utkarsh Sharma
The International Student Science Fair 2018
This experiment finds the activation energy of corn syrup using the Arrhenius equation. This was done through a simple experiment of dropping a ball into corn syrup and measuring its terminal velocity. From this, the viscosity could be derived, through the use of rearrangement of Newton’s First Law. The temperature of the corn syrup was also varied through the use of a microwave by raising it to 50 degrees Celsius. It is known that the more viscous a liquid is, the greater the activation energy for the liquid, which is essentially the energy barrier that a molecule has to overcome …

Energy Conversion System For Travelers (Ecost), Thipok Bovornratanaraks
The International Student Science Fair 2018
We have innovated “The Energy Conversion System for Travelers” or the ECoST. With the fact that most travelers have wheeled cabin-bags, whilst walking, the wheels will rotate so why don’t we harvest electricity from this kinetic energy? We thus install our innovation, the ECoST, to the bag to generate electricity from the spinning wheels. The electricity is then kept in the storage unit and ready to charge your empty battery devices in an emergency case via a USB port. To make life easy, our ECoST was designed to replicate the power bank charging method; therefore, we can charge …
