About:
- They use a variation of absorption spectroscopy that surpasses the systemic limits imposed by conventional absorption spectroscopy.
- With this technique, they can, in principle, illuminate the insides of cells and detect minuscule quantities of substances present there. The work was published in Nanoscale.
- Absorption spectroscopy is a tool to detect the presence of elements in a medium. Light is shone on the sample, and after it passes through the sample is examined using a spectroscope.
- Usually in absorption spectroscopy, the principle used is that light because of its wavelike nature, shows diffraction patterns, that is, dark and light fringes, when it scatters off any object. A related concept called the Abbe criterion sets a natural limit on the size of the object being studied.
About:
- The project entails retrofitting Diesel Electric Multiple Unit (DEMU) in 89 km Sonipat-Jind section of Northern Railway.
- The retrofitting of diesel-powered DEMU and converting it into hydrogen fuel-powered train set will not only save the cost to the tune of ₹2.3 crore annually by converting from diesel to hydrogen, but also save the carbon footprint (NO2) of 11.12 kilo tons per annum and particulate matter of 0.72 kilo tonnes per annum.
- Presently, very few countries are using this method. The trial of one rake is being done in Germany and the trial of the other in Poland.

When can the passport authority deny an applicant a passport?
Under Section 6(2) of the Indian Passports Act, 1967, the passport authority can refuse to issue a passport for specific reasons such as
- the applicant being not a citizen of India;
- that the applicant may engage, outside India, in activities prejudicial to the country’s sovereignty and integrity, or
- that the applicant’s departure may be detrimental to the country’s security; or
- that the person’s presence abroad may prejudice India’s friendly relations with a foreign country.
- Refusal of passport may also be related to a person’s antecedents. Conviction for any offence that involves “moral turpitude” with a sentence of not less than two years in the five preceding years would mean denial of passport.
- In January 2016, the Delhi High Court upheld the validity of Section 6(2)(f) of the Act, which allows the Centre to refuse a passport to anyone against whom criminal proceedings are pending.
