   A fully transparent solar cell can be made - a new study led by scientists from Incheon National University in Korea. The first transparent solar cell is demonstrated by an international team of researchers, led by Prof. Joondong Kim from Korea,. in Journal of Power Sources.  Their pioneering technique breaks on a specific part of the solar cell: the heterojunction, made up of thin films of materials accountable for absorbing light. The researchers were able to generate an efficient, transparent solar cell by combining the exclusive properties of titanium dioxide and nickel oxide semiconductors. After the Paris climate agreement, everyone is looking for carbon-free future. A vital part of this goal includes the energy conversion from fossil fuels to renewable sources such as solar, hydro, wind and wave energy. Among those, solar energy has been the foremost expectation in the professional community, as the utmost dependable and plentiful energy source on our planet. No...

                                       Bernoulli’s Principle                                           -   Dr. C. Dhayananth Jegan, M.E., Ph.D,      Bernoulli’s principle formulated by Daniel Bernoulli states that as the speed of a moving fluid increases (liquid or gas), the pressure within the fluid decreases. Although Bernoulli deduced the law, it was Leonhard Euler who derived Bernoulli’s equation in its usual form in the year 1752. Bernoulli’s principle states that - The total mechanical energy of the moving fluid comprising the gravitational potential energy of elevation, the energy associated with the fluid pressure and the kinetic energy of the fluid motion, remains constant.  Bernoulli’s principle can be derived f...
