Ministry of Coal has planted more than 217 lakh saplings during the last 5 years

Vijay Raman

Towards the commitment of environmental sustainability, Coal/Lignite PSUs under the Ministry of Coal have embarked on a concerted mission to achieve extensive afforestation goals. Coal/Lignite PSUs are making persistent efforts to minimise the footprints of coal mining through sustained reclamation and afforestation of areas in and around its operating mines. The reclamation activities are being carried out as per well-designed and approved mine closure plans, which carry detailed provisions regarding progressive as well as final mine closure activities.   The ongoing efforts of Coal/Lignite PSUs have resulted in the plantation…

New technology developed to transport of radio frequency (RF) through optical methods could improve digital & satellite communication

Vijay Raman

A newly designed prototypes in the Next-Generation Photonic Analog-to-Digital Converters (NG-PADC) project which can carry out instantaneous frequency measurement, generation and transport of Radio Frequency (RF) through optical methods could revolutionize various sectors, enabling faster digital communication, improved satellite communication, better medical imaging, and Photonic radars.   Analog-to-digital converters (ADCs) are critical components for developing the next generation of advanced digital receivers. The limitation of electronic ADCs (EADCs) is that their vertical resolution is compromised at high bandwidths. There are two possible approaches to solve this problem through Photonics.  …
