Laser radiation is widely used for eye surgery, with laser wavelength and operation mode depending on the ophthalmic procedure. Diabetic patients often suffer from proliferative diabetic retinopathy (PDR), a severe condition characterized by the formation of fragile new blood vessels on the retina's surface. These vessels are prone to leakage, potentially leading to retinal detachment and vision loss. Laser treatment is a widely adopted method to mitigate this issue, using light to seal blood vessels and coagulate adjacent retinal tissues. Compared to green laser, yellow laser has higher hemoglobin absorption and lower scattering within the eye, enabling lower power usage and enhanced precision. This research aimed to experimentally evaluate findings from earlier theoretical research highlighting the advantages of using yellow laser to treat PDR.

The project designed and developed a hydrogen-based hybrid energy storage system that ensures reliable electricity supply in remote areas disconnected from the grid. When renewable sources are insufficient, the stored hydrogen is converted into electricity through fuel cells, minimizing emissions. This integrated solution offers stable, clean energy and promotes sustainability by replacing fossil fuels. The project used excess solar and wind energy to produce hydrogen via electrolysis, which was then stored in high-pressure tanks. To handle short-term demand spikes, lithium-ion batteries provided instant backup. The project addressed the need for energy autonomy while mitigating environmental impact, showcasing a feasible approach for off-grid applications.
