Current Affairs Question - 23 April 2022

Consider the following statements:

1. Recently, Indian scientists from the Centre for Nano and Soft Matter Sciences (CeNS) designed an electrocatalyst system for energy-efficient hydrogen production with the help of electrolysis of urea.
2. The low-cost, earth-abundant Platinum-based catalysts are widely applied for this process.
3. The energy requirement for production of hydrogen through water electrolysis can be reduced by 70% through urea electrolysis.

Which of the above statement(s) is/are true?

Consider the following statements:

1. Recently, Indian Army’s Military Engineering Services (MES) constructed two houses using 3D Rapid Construction Technology.
2. 3D printing or additive manufacturing is a process of making three dimensional solid objects from a digital file. The creation of a 3D printed object is achieved using additive processes.
3. In an additive process an object is created by laying down successive layers of material until the object is created. Each of these layers can be seen as a thinly sliced cross-section of the object.

Which of the above statement(s) is/are true?

Consider the following statements:

1. Commissioned in May 2020, National Supercomputing Mission (NSM) is jointly led by Department of Science and Technology (DST) and Ministry of Electronics and Information Technology (MeitY).
2. Recently, the NSM deployed “PARAM Ganga”, a supercomputer at IIT Roorkee, with a supercomputing capacity of 1.66 Petaflops.
3. The system is designed and commissioned by Centre for Development of Advanced Computing (C-DAC).

Which of the above statement(s) is/are true?
