Researchers develop high-quality nanomechanical resonators with built-in piezoelectricity

Researchers at Chalmers University of Technology in Sweden and at the University of Magdeburg in Germany have developed a novel type of nanomechanical resonator that combines two important features: high mechanical quality and piezoelectricity. This development could open doors to new possibilities in quantum sensing technologies. Mechanical resonators have been used for centuries for a multitude of applications. A key aspect of these devices is their ability to vibrate at specific frequencies. A well-known example is the tuning fork. When struck, the tuning fork oscillates at its resonance frequency, producing a sound wave within our hearing range. With advancements in microfabrication techniques, researchers have been able to shrink mechanical resonators down to the micro- and nanometer scale. At these tiny sizes, resonators oscillate at much higher frequencies and exhibit a greater sensitivity compared to their macroscopic counterparts. "These properties make them useful in pre

Back to the history :- Mangalyaan took India to Mars on a budget smaller than a Bond film.....

The day was November 5, 2013, India embarked on a remarkable journey to Mars with the launch of Mangalyaan, the Mars Orbiter Mission (MOM), cementing its place in the global space community. Mission was accomplished from start to end by our jewel of nation i.e. the Indian Space Research Organisation (ISRO), this mission was no small feat; it was designed not only to explore Mars but to push the boundaries of India’s space capabilities. Within a year of it's launch, on September 24, 2014, Mangalyaan achieved what many considered impossible, becoming the first Asian spacecraft to reach Mars and the first in the world to do so on its maiden attempt. India’s leap into interplanetary space came at an astonishingly low cost. With a budget of approximately $72 million, Mangalyaan remains the most affordable Mars mission ever, showcasing ISRO’s ability to innovate under constraints. The mission aimed to study the Martian atmosphere, surface, and mineral composition, utilising five scientif

Bhagwat Geeta renowned for its wit and erudition

เคธเคฐ्เคตं เคช्เคฐเคฏोเคœเคจเคฎ् เค‰เคฆ्เคฆिเคถ्เคฏ เคเคต เคช्เคฐเคตเคฐ्เคคเคคे ।I One very good day, me along with my friends were discussing that if in reality karma fal exists. Digging deeper into the facts, and elaborating several stories, our faith on karmas strengthened. Out of curiosity, one pal highlighted that if Karma fal sustains then why do we believe in God, because if destiny is pre decided as per the deeds of our previous birth. And if, in current life, we are so loyal and honest towards our job and responsibilities then why do we need to be spiritually active. Discussion had turned out to be very serious and extreme awakening. Deep silence and much of bewilderness stretched. This discussion bullet points continued to inspire me to find out the essence of all suspicions and confusions. The Bhagwat Geeta ji, that is enough capable of justifying the extreme situations and all queries to much greater extent. Bhagwat Geeta ji states that always believe in god's plan and grace, absolutely it's the people'

Nanofibrils study successfully measures strength of spider web 'super fibers'

How small is "small?" Spider silk nanofibrils are just a few molecular layers thick, equivalent to approximately one ten-thousandth the diameter of a human hair. They're invisible to the naked eye and cannot be seen under an ordinary microscope. The findings are published in the journal Advanced Functional Materials. "We humans think we're so great and we can invent things, but if you just take a step outside, you find so many things that are more exciting." By weight, spider silk is approximately five times stronger than steel, but what makes the material even more impressive is its extensibility. The combination of strength and stretchiness allows it to absorb large amounts of energy. If humans find a way to replicate the structure of spider silk, it could be manufactured for use in practical applications. We could make a super bungee cord from it "Or a shield around a structure where we have something incoming at high velocity and we need to absorb a

Importance Of Financial Literacy Among Children - WORLD THRIFT DAY

World Thrift Day is celebrated annually on  31st October  worldwide. In  India, the day is celebrated on 30th October.  The day that stresses the significance with the intent of  raising awareness among people all around the world about the idea of saving their money in a bank  instead of keeping it under the mattress or at home. This promotes savings and financial security for not only the individuals but for the nation as a whole. Savings means ‘economising’ or ‘reserving’ a part of our regular income to be able to use it to make a bright future. Saving secure ones’ future and also preserves resources by avoiding wastage.  The day dedicated to highlighting the value of saving money and financial security. The term ‘thrift’ refers to use resources carefully and wisely so that they are not exhausted all at once. People should be educated on the need and the various ways of saving. The public especially younger ones should be taught the importance of depositing their money in banks so t

Journey of transforming dusky Sky to Blue Sky : IIT Grad’s Biodegradable Thermocol Prevents Stubble Burning

 When Delhi is struggling with it's worsening air quality index. There are population who are genuinely working for improving the air and diminishing the pollution in the city.  Young brilliant minds such as Delhi engineer Arpit Dhupar has built a biodegradable alternative to thermocol using stubble waste generated in the farms of Haryana and Punjab. This innovation is killing two birds with one stone.  Birthday party decor, school projects, scaffolding around the home, and, most often, packaging material —Thermocol is prime requirement and is inevitable  part of our lives, but comes with a heavy price of degrading the environment.  Its shock absorbance properties, lightweight texture, and versatility have rendered it a popular item for many needs and uses. Whereas such big advantages can't be compromised for the devastating impact that thermocol has on the planet.  The expanded form of polystyrene has been a popular choice for decades now, and falls under the category of polym
