Topic: Flexoelectricity

 Flexoelectricity: How Ice Can Generate Electricity Did you know that a simple block of ice can actually produce electricity? It may sound like science fiction, but scientists have recently discovered a fascinating property of ice: when it is bent, twisted, or stretched, it generates electric charges. This effect is known as flexoelectricity. What is Flexoelectricity? Flexoelectricity is a phenomenon where a material develops an electric polarization when it is mechanically deformed. Unlike piezoelectricity—which only occurs in certain crystals—flexoelectricity can occur in any solid material, including ice. This means that whenever ice is bent, compressed, or stretched, tiny electric charges are created inside it. Ice and Electricity Ice might seem like a simple frozen form of water, but it has a complex molecular structure. The water molecules in ice arrange themselves in a crystal-like pattern. When this structure is distorted—by bending, twisting, or stretching—the balance of e...

Lunar Eclipse

 Lunar Eclipse – 7 September 2025 By: Shahid Ullah Khan Physics Lecturer 📧 Email: shahidkhanphy85@gmail.com 📞 Contact: +92331-5107369 🌌 What is a Lunar Eclipse? A lunar eclipse occurs when the Earth comes between the Sun and the Moon, casting its shadow on the Moon. Unlike a solar eclipse, which can only be seen from limited regions, a lunar eclipse is visible from the entire night side of Earth. There are three main types of lunar eclipses: Penumbral Eclipse – when the Moon passes through Earth’s faint outer shadow. Partial Eclipse – when part of the Moon is covered by the Earth’s umbra. Total Eclipse – when the Moon is fully within Earth’s dark umbral shadow. 🌑 The Event of 7 September 2025 On 7 September 2025, a complete lunar eclipse will occur. During this celestial event, the Moon will enter Earth’s umbra completely, giving rise to a stunning “Blood Moon” effect. The Moon will appear reddish in color due to the scattering of sunlight through Earth’s atmosphere — the same ...
