    [pib] Iron-Manganese based Biodegradable Alloy

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Iron-Manganese based Biodegradable Alloy

    Mains level: Affordable medical devices and implants in India

    Indian scientists have jointly developed new generation Iron-Manganese based alloys for biodegradable metal implants for use in humans.

    Do you remember the Johnson and Johnson’s faulty hip implants case?? The alloy mentioned in the newscard can prove to be a gamechanger in the field of medical implants.

    Iron-Manganese based Biodegradable Alloy

    • Biodegradable materials (Fe, Mg, Zn, and polymer) can participate in the healing process and then degrade gradually by maintaining mechanical integrity without leaving any implant residues in the human body.
    • They are better alternatives to currently used metallic implants which remain permanently in the human body and can cause long-term side effects like systemic toxicity, chronic inflammation, and thrombosis.
    • The ARCI team employed both conventional melting and powder metallurgy techniques in the manufacturing of the new Fe-Mn based biodegradable alloys.
    • The alloy Fe-Mn (having Mn composition of more than 29% by weight) is a promising biodegradable metallic implant which exhibits a single austenitic phase (a non-magnetic form of iron) with MRI compatibility.

    Easy degradation

    • The alloy also showed a degradation rate in the range of 0.14-0.026 mm per year in the simulated body fluid.
    • It means that the Fe-Mn alloy exhibits mechanical integrity for 3-6 months and completely, disappears from the body in 12-24 months.
    • During the degradation process, calcium phosphate deposits on the implant due to local alkalization and saturation of calcium and phosphate, allow cells to adhere onto the surface to form tissues.

    Benefits

    • The Fe-Mn alloy produced at ARCI exhibited 99% density with impressive mechanical properties and behaved as a nonmagnetic material even under a strong magnetic field.
    • These properties are comparable to presently used permanent Titanium (Ti) and stainless-steel metallic implants (which is very costly).

    [pib] Atmanirbhar Bharat Abhiyan (Self-reliant India Mission)

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Atmanirbhar Bharat Abhiyan

    Mains level: Significance and need for such a mission

    The PM has announced the Atma-nirbhar Bharat Abhiyan (or Self-reliant India Mission) and said that in the days to come the government would unveil the details of an economic package — worth Rs 20 lakh crore or 10% of India’s GDP in 2019-20 — aimed towards achieving this mission.

    Try a question:

    ‘Doubling Farmer’s Income’ and ‘USD 5 trillion economy’  seems more like slogans today in wake of COVID pandemic. Comment on the statement with keeping in view the Atmanirbhar Bharat Abhiyan of the government.

    Atmanirbhar Bharat: With a special package

    • PM has announced a special economic package and gave a clarion call for Self-reliant India.
    • The package will provide a much-needed boost towards achieving self-reliance.
    • This package, taken together with earlier announcements by the government during COVID crisis and decisions taken by RBI, is to the tune of Rs 20 lakh crore, which is equivalent to almost 10% of India’s GDP.
    • The package will also focus on land, labour, liquidity and laws. It will cater to various sections including cottage industry, MSMEs, labourers, middle class, and industries, among others.

    Five pillars of a self-reliant India

    PM iterated that a self-reliant India will stand on five pillars viz.

    1) Economy, which brings in quantum jump and not incremental change

    2) Infrastructure, which should become the identity of India

    3) System, based on 21st-century technology-driven arrangements

    4) Vibrant Demography, which is our source of energy for a self-reliant India and

    5) Demand, whereby the strength of our demand and supply chain should be utilized to full capacity

    Is this a new package?

    • The PM did not give the details, but he specified that this calculation of Rs 20 lakh crore includes what the government has already announced and the steps taken by the RBI.
    • This means the total amount of additional money — that is over and above what the government would have spent even in the absence of a Covid crisis — will not be Rs 20 lakh crore.
    • It would be substantially less.

    Why?

    • That’s because the PM has included the actions of RBI, India’s central bank, as part of the government’s “fiscal” package, even though only the government controls the fiscal policy and not the RBI (which controls the ‘monetary’ policy).
    • Government expenditure and RBI’s actions are neither the same nor can they be added in this manner.

    What did the RBI provide earlier?

    • A rough estimate suggests that the RBI’s decisions have provided additional liquidity of Rs 5-6 lakh crore since the start of the Covid-19 crisis.
    • Add this to the Rs 1.7 lakh crore of the first fiscal relief package announced by the Centre on March 26. Together, the two already account for 40 per cent of the Rs 20-lakh crore package.
    • That leaves an effective amount of Rs 12 lakh crore.
    • However, if the government is including RBI’s liquidity decisions in the calculation, then the actual fresh spending by the government could be considerably lower than Rs 12 lakh crore.
    • That’s because RBI has been coming out with long term bond-buying operations (long term repo operation or LTRO, to infuse liquidity into the banking system) worth Rs 1 lakh crore at a time.
    • If for argument’s sake, RBI comes out with another LTRO of Rs 1 lakh crore, then the overall fiscal help falls by the same amount.

    Why shouldn’t RBI’s package be included in the overall package?

    • That is because direct expenditure by a government — either by way of wage subsidy or direct benefit transfer or any, immediately and necessarily stimulates the economy.
    • In other words, that money necessarily reaches the people — either as someone’s salary or someone’s purchase.
    • But credit easing by the RBI — that is, making more money available to the banks so that they can lend to the broader economy — is not like government expenditure.
    • That’s because, especially in times of crisis, banks may take that money from RBI and elsewhere and, instead of lending it, park it back with the RBI.

    Back2Basics: Long Term Repo Operations (LTRO)

    • The LTRO is a tool under which the RBI provides 1-3 year money to banks at the prevailing repo rate, accepting government securities with matching or higher tenure as the collateral.
    • Funds through LTRO are provided at the repo rate.
    • But usually, loans with higher maturity period (here like 1 year and 3 years) will have a higher interest rate compared to short term (repo) loans.
    • According to the RBI, the LTRO scheme will be in addition to the existing Liquidity Adjustment Facility (LAF) and the Marginal Standing Facility (MSF) operations.
    • The LAF and MSF are the two sets of liquidity operations by the RBI with the LAF having a number of tools like repo, reverse repo, term repo etc.

    What are Repo and Reverse Repo rates?

    • The repo rate is the rate at which the RBI lends money to the banking system (or banks) for short durations.
    • The reverse repo rate is the rate at which banks can park their money with the RBI.
    • With both kinds of the repo, which is short for repurchase agreement, transactions happen via bonds — one party sells bonds to the other with the promise to buy them back (or repurchase them) at a later specified date.
    • In a growing economy, commercial banks need funds to lend to businesses.
    • One source of funds for such lending is the money they receive from common people who maintain savings deposits with the banks. Repo is another option.
  • Industrial Sector Updates – Industrial Policy, Ease of Doing Business, etc.

    [pib] Seasonal rapid advancement of Surging Glaciers in Karakoram Range

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Glaciers mentioned in the newscard

    Mains level: Glacial surges and their impacts

    Indian researchers have found a seasonal advancement in 220 surge-type glaciers in the Karakoram Range of Ladakh.

    Points to note:

    1) Open you map and revise the glaciers of Himalayan region.

    2) Glacial landforms as Geographic phenomenon.

    What are Glacial Surges?

    Click here to see the animated view

    • Glacial surges are short-lived events where a glacier can advance substantially, moving at velocities up to 100 times faster than normal.
    • Until recently, most glaciologists believed that a glacier’s physical characteristics, such as its thickness and shape, and the properties of the terrain it sits on determining whether it can surge.
    • Now, it is proved to believe an external factor also plays a major role: water from precipitation and melting.
    • Pooling on the surface, it can infiltrate the glacier through crevasses and reach its base, warming, lubricating, and, ultimately, releasing the ice.

    Why surging in the Karakoram is a concern?

    • The behaviour of these glaciers, which represent 40% of the total glaciated area of the Karakoram, goes against the normal trend.
    • Surging of glaciers is potentially catastrophic as it can lead to the destruction of villages, roads and bridges.
    • It can also advance across a river valley and form the ice-dammed lake.
    • These lakes can form catastrophic outburst floods.
    • Therefore, monitoring of glacier surges, ice-dammed lake formation, and drainage is of paramount importance.

    Which are these glaciers?

    • The scientists focused on the Shispare and Muchuhar glaciers, former tributaries of the once larger Hasanabad Glacier situated in Hunza Valley, Gilgit-Baltistan.

    Significance of the study

    • The Surge-type glaciers oscillate between brief (months to years) rapid flow and lengthy (tens to hundreds of years) slow flow or stagnation, which are called the ‘active’ (or ‘surge’) and ‘quiescent’ phases, respectively.
    • This unsteady glacier flow makes it difficult to accurately assess individual glacier mass balances using in-situ observations.
    • The study will help to understand the diversity of glacial behaviour and help make accurate assessments of individual glacier mass balances for disaster planning and management.

    [pib] Energy-efficient Photodetector for Security Application

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Photodetectors and their applications

    Mains level: NA

    Indian scientists have fabricated an economical and energy-efficient wafer-scale photodetector using gold – silicon interface, for security applications.

    A basic question on the working principle of Photodetectors can be asked in the Prelims.

    What are Photodetectors?

    • Photodetectors, also called photosensors, are sensors of light or other electromagnetic radiation.
    • A photodetector has a p–n (positive-negative) junction that converts light photons into the current.
    • The absorbed photons make electron-hole pairs in the depletion region.
    • Photodiodes and phototransistors are a few examples of photodetectors. Solar cells convert some of the light energy absorbed into electrical energy.
    • The material cost and the intricate fabrication processes involved in realizing high-performance detectors make them unaffordable for day to day applications.

    Applications

    • Photodetectors are the heart of any optoelectronic circuit that can detect light.
    • They are employed for a wide variety of applications ranging from controlling automatic lighting in supermarkets to detecting radiation from the outer galaxy as well as security-related applications.
    • They range from simple devices that automatically open supermarket doors, to receivers on the TV remote controls.

    What did Indian researchers achieve?

    • The scientists have fabricated gold (Au) – silicon (Si) interface, which showed high sensitivity towards light demonstrating the photodetection action.
    • The Au–Si interface was brought about by galvanic deposition, a technique for electroplating of metals, wherein water-based solutions (electrolytes) are used, which contain the metals to be deposited as ions.
    • In addition, a nanostructured Au film also was deposited on top of p-type silicide (having an excess of positive charges), which acts as a charge collector.

    Benefits

    • Being a solution-based technique, the method is highly economical and enabled large-area fabrication without compromising the detector response.
    • The process is quick, taking only minutes to fabricate a detector of any arbitrary area and exhibited a rapid response of 40 microseconds.
    • This photodetector displayed long-term environmental stability.
    • The Indian invention provides a simple and cost-effective solution-based fabrication method for high-performance photodetector.
    • It could help detect weak scattered light as an indication of unwanted activity.
