Free online Python course Hex N Bit has recently launched a free entrey-level online course on Python. The duration is 150 minutes and includes self-paced e-learning videos, codes, projects and quizzes. Upon completion, the company will provide a recognised certificate. Through this initiative, the company’s aims to provide exposure to candidates for in-demand technologies and hopes to build confidence in students and make coding truly fun and easy to practice. Apart from this, Hex N Bit plans to launch more such free resources with projects in the fields of Artificial Intelligence, Intern...

Date Time New tech builds ultralow-loss integrated photonic circuits Integrated silicon nitride photonic chips with meter-long spiral waveguides. Credit: Jijun He and Junqiu Liu (EPFL). EPFL scientists have developed ultralow-loss silicon nitride integrated circuits that are central for many photonic devices, such as chip-scale frequency combs, narrow-linewidth lasers, coherent LiDAR, and neuromorphic computing. Encoding information into light, and transmitting it through optical fibers lies at the core of optical communications. With an incredibly low loss of 0.2 dB/km, optical fibers made f...

22 Apr 2021 Silicon nitride-based PICs offer “record low optical losses” as well as smaller footprints. Integrated silicon nitride photonic chips with meter-long spiral waveguides. Integrated photonic chips are usually made from silicon that is abundant and has good optical properties. But silicon cannot perform every required function in integrated photonics, so new material platforms have emerged. One of these is silicon nitride (Si 3N 4), whose exceptionally low optical loss – orders of magnitude lower than that of silicon – has made it the material of choice for appl...

The developed nanomaterial can clean the mask by simply keeping it in bright sunlight and make it ready to wear again

Share Mandi: Indian Institute of Technology Mandi researchers have developed a virus-filtering, self-cleaning and antibacterial material that can be used to make face masks and other PPE equipment. This path breaking development of Dr. Amit Jaiswal, Assistant Professor, School of Basic Sciences, IIT Mandi, along with his research scholars, Mr. Praveen Kumar, Mr. Shounak Roy, and Ms. Ankita Sarkar comes at a time in which it has become imperative to develop techniques to stop the second wave of the COVID-19 pandemic in the country. Results of this work have recently been published in the prest...
