    superconductivity

    Central Idea

    • Recently, two South Korean researchers sparked excitement in the physics community by claiming to have achieved Superconductivity at room temperature.
    • They claim to have developed a lead-based compound exhibiting superconducting properties at normal room temperature and pressure (NTP) conditions.

    NTP (Normal Temperature and Pressure):

    Normal Temperature: Defined as 20 degrees Celsius (20°C) or 293.15 Kelvin (K).

    Normal Pressure: Defined as 1 atmosphere (atm) or 101.325 kilopascals (kPa), which is the same pressure as STP.

    NTP is another standard set of conditions used for specific applications, but it is less commonly used than STP.

    STP (Standard Temperature and Pressure):

    Standard Temperature: Defined as 0 degrees Celsius (0°C) or 273.15 Kelvin (K). At this temperature, the average kinetic energy of gas molecules is minimal.

    Standard Pressure: Defined as 1 atmosphere (atm) or 101.325 kilopascals (kPa). This is the average atmospheric pressure at sea level.

    STP is often used to express gas properties and perform calculations under uniform conditions to allow for meaningful comparisons between different gases or processes.

    What is Superconductivity?

    • Zero Resistance: Superconductivity occurs when a material offers almost zero resistance to the flow of electric current, enabling energy-efficient electrical appliances and lossless power transmission.
    • Magnetic Behavior: Superconductors also display fascinating behavior under magnetic fields, enabling technologies like MRI machines and superfast Maglev trains.

    Exploring the Material LK-99

    • Apatite Structure: The Korean group utilized copper-substituted lead apatite, a phosphate mineral with unique tetrahedral motifs, to create LK-99.
    • Superconducting Behavior: LK-99 displayed essential superconducting properties, with almost zero resistance to current flow and sudden emergence of resistance above a critical current threshold.
    • Magnetic Resilience: LK-99 retained superconductivity even under the presence of a magnetic field until reaching a critical threshold.

    Current Superconductors and Their Limitations

    • Earlier Discoveries: In the 1980s, scientists found copper oxide materials exhibiting superconductivity above -240°C. Subsequent research yielded limited success in achieving higher temperatures.
    • Extreme Conditions: Existing superconductors operate at extremely low temperatures, often below -250°C, close to absolute zero (-273°C).
    • Critical Temperatures: Materials like Mercury, Lead, and Aluminum, Tin, and Niobium exhibit superconductivity at critical temperatures just above absolute zero.
    • High-Temperature Superconductors: Some materials, labelled ‘high-temperature’ superconductors, display superconducting properties below -150°C.

    Scientific Community’s Response

    • Cautious Optimism: The scientific community responded cautiously to the claims of LK-99’s room-temperature superconductivity, given previous controversies and unverified claims.
    • Technical Errors: Some data in the research papers raised questions and were deemed “sloppy” or “fishy” by independent scientists.
    • Replication Efforts: Numerous research groups worldwide are attempting to reproduce the results to validate the claim.
    • Mixed Perspectives: The authors’ unwavering confidence in their work contrasts with certain aspects of the research that appear hurried or contentious.

    Conclusion

    • The search for room-temperature superconductors represents a holy grail in science, promising immense rewards and recognition.
    • Although the recent claim by South Korean researchers has captured attention, it awaits rigorous validation.

    What is Zero FIR?

    Prelims Only | Governance | Mains Paper 2: Laws, Institutions & Bodies Constituted For The Vulnerable Sections

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Zero FIR

    Mains level: Not Much

    zero FIR

    Central Idea

    • Recent incidents of violence and crime in Manipur have brought the concept of the ‘Zero First Information Report (FIR)’ into the spotlight.
    • The Supreme Court has sought for all data regarding such FIRs in Manipur Gangrape Incidence.

    What is Zero FIR?

    • Provision and Purpose: Zero FIR allows any police station to register an FIR for a cognisable offence without assigning a regular FIR number initially.
    • No diary: Whereas FIRs have serial numbers assigned to them, zero FIRs are assigned the number ‘0’. Hence the name.
    • Swift Action: The relevant police station subsequently registers a fresh FIR and commences the investigation.
    • Focus on Victims: It is designed to expedite complaint lodging, particularly for serious crimes involving women and children, without the need to approach multiple police stations.
    • Preserving Evidence: Early registration helps prevent the loss or tampering of crucial evidence and witnesses.
    • Transferred Jurisdiction: The Zero FIR is later transferred to the relevant police station where the offence occurred or where the investigation should be conducted.

    How does it work?

    • After a police station registers a zero FIR, it has to transfer the complaint to a police station that has the jurisdiction to investigate the alleged offence.
    • Once a zero FIR is transferred, the police station with the appropriate jurisdiction assigns it a serial number, thereby converting it into a regular FIR.

    Legal Provisions for Zero FIR

    The provision of Zero FIR finds support in various judgments and recommendations.

    • Satvinder Kaur vs. State (1999): The Delhi High Court held that a woman has the right to lodge her complaint from any place other than where the incident occurred.
    • Justice Verma Committee (2012): The introduction of Zero FIR was based on the recommendation of the Justice Verma Committee, which was formed in response to the 2012 Nirbhaya gangrape case.
    • Lalita Kumari vs. Govt. of UP (2014): The Supreme Court ruled that registration of an FIR is mandatory when information discloses the commission of a cognizable offence.

    Back2Basics: First Information Report (FIR)

    • Essential Document: An FIR is a written document prepared by the police upon receiving information about a cognisable offence.
    • What is a cognisable offences? It is when an officer can arrest a suspect without a court’s warrant if/she has “reason to believe” that the person committed the offence and arrest is necessary based on certain factors.
    • Triggering Investigation: It serves as the first step towards initiating the investigation process and subsequent police actions.
    • Registration for Cognizable Offences: Section 154(1) of the Criminal Procedure Code (CrPC) empowers the police to register an FIR for cognizable offences.
    • Punishment for Non-Registration: Section 166A of the Indian Penal Code (IPC) provides punishment for public servants failing to record information related to a cognizable offence, with imprisonment of up to two years and a fine.

  • Foreign Policy Watch: India-China

    China’s Use of Stapled Visas and its Implications for India

    Prelims Only | International Relations | Mains Paper 2: Bilateral, Regional and Global Groupings and agreements involving India

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Stapled Visa

    Mains level: Not Much

    stapled visa

    Central Idea

    • The issuance of stapled visas by China to Indian nationals from Arunachal Pradesh and Jammu and Kashmir has been a contentious issue between the two countries.

    What is Stapled Visa?

    • A Stapled Visa is an unstamped piece of paper attached to the passport, different from a regular visa that is affixed and stamped.
    • China has been issuing stapled visas to Indian nationals from certain regions, notably Arunachal Pradesh and Jammu and Kashmir, which are territories that China disputes with India.
    • By using stapled visas for residents of these regions, China is making a unilateral claim over the disputed territories, suggesting that it considers them as part of its own territory.

    China’s Dispute over Indian Territory:

    • Sovereignty Dispute: China disputes India’s sovereignty over Arunachal Pradesh and questions the legal status of the McMahon Line, the boundary agreed upon between Tibet and British India in 1914. This dispute underlies Chinese claims over the Line of Actual Control (LAC) and its repeated border transgressions into Indian Territory.
    • Unilateral Claim: China claims approximately 90,000 sq km of Arunachal Pradesh as its territory, referring to it as “Zangnan” or “South Tibet.” Chinese maps often depict Arunachal Pradesh as part of China.

    Use of Stapled Visas:

    • Signaling Intentions: Chinese state media began referring to Arunachal Pradesh as “South Tibet” in 2005. In 2006, China refused to grant a visa to an Indian government official serving in Arunachal Pradesh. Subsequently, China started issuing stapled visas to all Indian citizens from Arunachal Pradesh and Jammu and Kashmir.
    • Timeline of Events: Stapled visas for Jammu and Kashmir residents appeared around 2008-09. Over the years, China repeatedly issued stapled visas to Indian nationals, including sports athletes, weightlifters, and archers, leading to tensions between the two countries.

    India’s Response and Stance

    • Protest and Diplomatic Efforts: The Indian government has consistently protested against the issuance of stapled visas and conveyed its stance to China, asserting that there should be no discrimination based on domicile or ethnicity in the visa regime for Indian citizens.
    • Refusal to Accept Stapled Visas: India has refused to accept stapled visas as valid travel documents and cautioned Indian citizens that such visas are not considered valid for travel out of the country.
    • Sovereignty Assertion: India firmly asserts its sovereignty over Arunachal Pradesh and maintains that stapled visas undermine its territorial integrity.
