The corridor will serve 12 stations and includes India’s first undersea rail tunnel, which runs about 7 km beneath Thane Creek, and the first service on it is targeted for August 2027.

The backgrounder states that the 2026 railway timetable speeded up 549 trains across the network, and it breaks that total into four bands.

India noted that it had hosted the world’s largest artificial intelligence summit in February this year, and said Switzerland would carry that journey forward through the Geneva AI Summit next year, with both countries committed to making artificial intelligence responsible, inclusive and human-centric.

The summit produced an agreement on transport, mobility and infrastructure, which builds on Swiss involvement in the Varanasi ropeway, the Jewar airport at Noida and railway and tunnelling work in hill areas, so option C was indeed signed.

The agreement is described as an ambitious blueprint for investment, innovation, jobs and shared prosperity, and the two sides expect it to deliver investment of 100 billion dollars in India together with 10 lakh direct jobs across a span of 15 years.

The Trade and Economic Partnership Agreement that took effect in October of the previous year was concluded between India and the EFTA countries, and it is the first free trade agreement India has with any economic bloc in Europe.

The Technology Development Board, the body that signed the agreement with BigEndian Semiconductors and that administers the Research Development and Innovation Fund, works under the Department of Science and Technology, Government of India.

The agreement states that the project must lift the technology from Technology Readiness Level 5, where it stands now, to Technology Readiness Level 9, the stage at which a product has proved itself in actual use rather than in a laboratory.

Project VeerAI is building a single piece of silicon that lets a camera do its own thinking, combining artificial intelligence processing with security, privacy and connectivity features on a sovereign technology platform.

The Technology Development Board, which works under the Department of Science and Technology, agreed to give BigEndian Semiconductors of Bengaluru exactly this amount out of the Research Development and Innovation Fund, and the money is being routed through Optional Convertible Debt rather than as an outright grant.

The new site proposed for its Dark Matter Laboratory lies at the 815-metre level of the Jaduguda underground mine, and the Chief Guest at UCIL's Diamond Jubilee Year celebrations was taken to see it along with the Technology Demonstration Pilot Plant.

Ms. Seema Jain attended the jubilee at Jaduguda in that capacity as Chief Guest, toured the Technology Demonstration Pilot Plant and the proposed site of the Dark Matter Laboratory, and described the year as a celebration of six decades of scientific capability, institutional experience and service to the nation, paying…

UCIL is described as a public sector enterprise working under the Department of Atomic Energy, and it supplies the uranium that feeds the country's nuclear power programme.

When a solid is divided into nanoparticles its total surface area grows enormously while the mass stays the same, so a very large fraction of the atoms lies exposed on the surface with unsatisfied bonds; chemical reactions happen at surfaces, so reactivity and catalytic activity rise sharply, which is why…

Gerd Binnig and Heinrich Rohrer built it at the IBM laboratory in Zurich in 1981; a sharp metal tip is moved a fraction of a nanometre above a conducting surface and the quantum tunnelling current between tip and sample maps the atoms one by one, work that brought them the…

The Nobel Prize in Chemistry of 2023 went to Moungi Bawendi, Louis Brus and Alexei Ekimov for the discovery and synthesis of quantum dots, semiconductor nanocrystals whose emitted colour depends on their size because of quantum confinement, and which are used in television displays, in light emitting diodes and as…

In 1911 the Dutch physicist Heike Kamerlingh Onnes, who had already liquefied helium, cooled mercury to about four kelvin and found that its electrical resistance vanished completely, which is the discovery of superconductivity and won him the Nobel Prize in Physics in 1913.

Nitinol is an alloy of roughly equal parts nickel and titanium, and even its name records this, being formed from nickel, titanium and the Naval Ordnance Laboratory where it was developed.

The Nano Mission, formally the Nano Science and Technology Mission, was launched in 2007 under the Department of Science and Technology, which had already been running the Nano Science and Technology Initiative since 2001, and the mission works on basic research, human resources, infrastructure and the transfer of results to…
