PM announces special economic package of Rs 20 trillion
Prime Minister Shri Narendra Modi addressing the nation on 12 May, said that the crisis that has emerged due to COVID-19 is unprecedented, but in this battle, we not only need to protect ourselves but also have to keep moving forward, through ensuring that the country becomes self-reliant. He clarified that self-reliance, is different from being self-centered. He said that a self-reliant India will stand on five pillars viz. Economy, which brings in quantum jump and not incremental change; Infrastructure, which should become the identity of India; System, based on 21st century technology driven arrangements; Vibrant Demography, which is our source of energy for a self-reliant India; and Demand, whereby the strength of our demand and supply chain should be utilized to full capacity. He underlined the importance of strengthening all stakeholders in the supply chain to increase, as well as fulfill, the demand. Prime Minister announced a special economic package of Rs 20 trillion which is equivalent to almost 10% of India’s GDP. He said that the package will provide a much needed boost towards achieving ‘Atmanirbhar Bharat’. 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. Prime Minister remarked that self-reliance will prepare the country for tough competition in the global supply chain, and it is important that the country wins this competition. The same has been kept in mind while preparing the package. It will not only increase efficiency in various sectors but also ensure quality. He observed that the crisis has taught us the importance of local manufacturing, local market and local supply chains. All our demands during the crisis were met ‘locally’. Now, it’s time to be vocal about the local products and help these local products become global.

SCTIMST develops 2 types of swabs for COVID-19 testing
Researchers at the Thiruvananthapuram based Sree Chitra Tirunal Institute for Medical Sciences and Technology (SCTIMST), have developed two types of nasal and oral swabs and viral transport medium for COVID-19 testing. Chitra EmBed flocked nylon swabs, and Chitra EnMesh, polymeric foam-tipped, lint-free swabs with flexible plastic handles developed have both proven efficiency in the adequacy of specimen collection and rapid elution (extracting one material from another by washing with a solvent) of specimen into the liquid viral medium. They also have good recovery of viral RNA collected using these swabs and medium. The swabs will be available as sterile, ready-to-use devices. The swabs are designed for efficiency and comfort in the working environment and help in improved specimen collection with minimum discomfort to patients. Their safe and convenient breakpoint ensures minimal contact of the health worker with the sample during packing. The second innovation, Chitra Viral Transport Medium, is specifically designed to retain the virus in its active form during its transportation from the collection point to the laboratory. Technologies for both swabs and viral transport medium have been transferred to two industries for immediate manufacture and sales - Mallelil Industries, Origin diagnostics, and Levram Life sciences.

Portable, reusable test-kits for Covid-19 developed
University of Utah has developed a reusable and portable coronavirus sensor, based on technology being developed to detect Zika virus, whihc will now be converted to work with COVID-19. With just a drop of saliva it can detect COVID-19 within 60 seconds. The sensor would use single-strand DNA called aptamers in the sensor that would attach to the proteins in the COVID-19 virus molecule and an electrical resistance is measured in the device, signaling a positive result, if it is present. A small sensor connects into the cellphone’s power jack and an app is launched. A drop of saliva is dropped on the sensor, and the results would appear on the phone. It is designed to also test for the virus on the surface, brushing a swab on the surface and then on the sensor. It might also be able to detect the presence of COVID-19 in floating microscopic particles in the air and in enclosed spaces such as an elevator. The sensor is designed to be reusable as it can destroy the previous sample by producing a small electrical current that could heat up and remove or disintegrate the virus. The NSF has granted USD 200000 to support development.

New vaccine platform applicable to various viruses
A Korean research team has developed a new vaccine platform which uses RNA as an immunostimulatory agent known as an adjuvant and consists of compounds that maintain the stability of the RNA and spike protein that the virus uses to invade the host cell. The team mixed the RNA of the cricket paralysis virus, and an RNA stabilizer containing zinc complex. A vaccine was created using the mixture, along with the spike protein of the MERS-CoV, and administered to a group of mice. After just one inoculation, the vaccine was shown to have adequate protective efficacy (100% protective efficacy against lethal doses of the virus). The MERS-CoV infection was also suppressed through the induction of high neutralizing antibodies (PRNT80 titer > 1:2,560) when the same vaccine was administered to macaque monkeys, which are nonhuman primates. RNA adjuvant and stabilizer mixed together can be applied to most vaccine types, including protein-based vaccines and inactivated vaccines, meaning that they have a wide range of potential uses. The team measured the amount of antibodies (neutralizing-antibody values) and conducted a virus challenge experiment. The research team has formed a consortium with SK Bioscience, to manage the development of a COVID-19 vaccine.

Gilead signs licensing agreement for remdesivir with Indian companies
US drug maker Gilead Sciences has signed non-exclusive voluntary licensing agreements with five generic drug makers based in India and Pakistan on anti-viral drug Remdesivir, seen as a potential therapy for COVID19. Indian companies Cipla Ltd, Hetero Labs Ltd, Jubilant Life Sciences and Mylan and Pakistani firm Ferozsons Laboratories has signed the commercial agreement that allows the companies to manufacture remdesivir for distribution in 127 countries, including India. A statement from the US drug maker says the 127 nations include nearly all low-income, lower middle-income & several upper-middle and high-income countries that face significant obstacles to healthcare access. The USFDA has granted Emergency Use Authorization (EUA) for remdesivir to treat Covid-19, despite limited trial data to prove safety and efficacy of Remdesivir. Japan has approved the drug for COVID-19 treatment in severely-ill coronavirus patients. In the current agreement the five generic drug companies will receive a technology transfer of Gilead's manufacturing process to scale up production and make the drugs available. Gilead says the licensees also set their own prices for the generic product they produce. The licenses are royalty-free until the World Health Organization declares the end of the Public Health Emergency of International Concern regarding COVID-19 or until a pharmaceutical product other than remdesivir or a vaccine is approved to treat or prevent COVID-19, whichever is earlier, according to the Gilead statement. The remdesivir licensing agreement is on lines of the voluntary licences Gilead had signed in 2014 with 9 Indian companies for its blockbuster Hepatitis drug Sofobuvir

Next-generation solar cells can withstand heat, maintain efficiency
Iowa State University researchers have found a way to exploit perovskite’s useful properties while stabilizing the cells at high temperatures. First, the team did away with organic components in the material, particularly cations, materials with a positive charge, and substituted inorganic materials such as cesium. That made the material stable at higher temperatures. And second, they developed a fabrication technique that builds the perovskite material one thin layer - just a few billionths of a meter - at a time. This vapor deposition technique is consistent, leaves no contaminants, and is already used in other industries so it can be scaled up for commercial production. The new perovskite solar cells show no thermal degradation even at 200 degrees Celsius for over three days, temperatures far more than what the solar cell would have to endure in real-world environments. The new inorganic perovskite solar cells have a photoconversion efficiency of 11.8 percent. Further developments include using new combinations of materials. The greater thermal stability of inorganic perovskite materials and solar cells at higher temperatures and over extended periods of time are promising for the commercialization of perovskite solar cell materials.
New technology revolutionizes 3D metal printing
A team at TU Graz has developed Selective LED-based melting (SLEDM) i.e. the targeted melting of metal powder using high-power LED light sources for 3D metal printing and has now applied for a patent. The technology is similar to selective laser melting (SLM) and electron beam melting (EBM), in which metal powder is melted by means of a laser or electron beam and built up into a component layer by layer. However the SLEDM process uses a high-power LED beam to melt the metal powder. The light-emitting diodes were specially adapted and equipped with a complex lens system by which the diameter of the LED focus can be easily changed between 0.05 and 20 millimetres during the melting process. This enables the melting of larger volumes per unit of time, reducing the production time of components for fuel cell or medical technology, for example, by a factor of 20 on average. This technology is combined with a newly designed production plant which adds the component from top to bottom. The process will be used to produce bioresorbable metal implants, i.e. preferably screws made of magnesium alloys that are used for bone fractures. SLEDM enables the production of such implants directly in the operating theatre. The second focus is on production of components such as bipolar plates for fuel cells or components for battery systems.

Supercapacitor promises storage, high power and fast charging
Researchers at Penn State and two universities in China have developed a new supercapacitor by combining Manganese oxide with cobalt manganese oxide, forming a hetero-structure which when coupled to a semiconductor, makes a conductive interface with a low resistance to electron and ion transport. They used an easy, low-cost, two-step method to controllably grow MnO2 nanorods directly on CoMn2O4 nanosheets (i.e., MnO2@CoMn2O4) with robust adhesion. The controllable heterostructures exhibit significantly improved electrochemical capacitive performance, including remarkable specific capacitance, excellent rate capability, and cycling stability. Furthermore, exploring MnO2@CoMn2O4 as positive electrode and N-doping 3D reduction of graphene oxide (N-3DrGO) as negative electrode yielded an asymmetric supercapacitor with high energy density (230.57 mWh cm-2), remarkable power density (3.91 mW cm-2 at 149.99 mWh cm-2), and excellent cycling stability (81.3% capacitance retention after 5000 cycles at 3 mA cm-2). This work offers new opportunities to explore high-performance electrode materials by providing methods to control the interface in nano-heterostructures.
Filtering out toxic chromium from water
Chemists at EPFL Switzerland are developing energy efficient processes for removing hexavalent chromium from water, using sponge-like materials called metal-organic frameworks (MOF) that can collect specific substances from solution. The materials are extremely porous and offer very great contact surface area. The target substance then enters these pores and sticks to the internal surface area in a process called adsorption. The scientists have previously shown that their materials can efficiently adsorb other substances dissolved in solution, like gold, mercury and lead. For instance, 1 gram of MOF yields almost 1 gram of gold. The team has now demonstrated the extraction of hexavalent chromium from water and the MOFs can extract approximately 208 milligrams per gram of MOF. Also, when light is shined on the MOF, it then transforms the highly toxic hexavalent chromium into relatively nontoxic trivalent chromium. Further developments are required in order to implement the technology for decontaminating water outside of the laboratory. The sponges are they are relatively easy and cheap to make. The cost of 1 kg of MOFs to cost roughly 15 CHF. This development could lead to better access to clean water and extraction of valuable metals from seawater.

Wuhan Lab develops Fossil-Fuel Jet Propulsion with Air Plasmas
A team of researchers at Wuhan University has demonstrated a prototype device that uses microwave air plasmas for jet propulsion. It could solve the problems of global warming caused by the use of fossil fuel combustion engines. The design requires no fossil fuel and causes no carbon emissions. The researchers created a plasma jet by compressing air into high pressures and using a microwave to ionise the pressurised air stream. The plasma jet thruster generates the high-temperature, high-pressure plasma in-situ using only injected air and electricity. The results demonstrated the jet engine based on microwave air plasma was a potentially viable alternative to the conventional fossil fuel jet engines. The prototype plasma jet device can lift a 1 kg steel ball over a 24mm diameter quartz tube, where the high-pressure air is converted into a plasma jet by passing through a microwave ionisation chamber. By building a large array of these thrusters with high-power microwave sources, the prototype design can be scaled upto a full-sized jet.
UOC research improves the quality of CT scan imagery
Computed tomography, or CT is among the most common imaging tools used to guide biopsy and radiation therapy as well as monitoring the effectiveness of treatments like cancer treatment, internal injuries, and bleeding detection. However, CT scan involves the risk due to the exposure of the body to high-dose X-rays. Scientists at the University of Catalonia (UOC) have developed a new post-processing algorithm which increases the quality of reconstructed CT images. The method increases the capacity to distinguish between tissues by 60% in simulations compared to conventional CT. The post-processing approach did not require substantial hardware reconfiguration and gave more freedom to imaging scientists for further exploration. The examination of the findings of the study in a clinical setting could reduce the radiation exposure to X-rays

NTU Singapore develops sustainable way to extract chitin
Scientists at the Nanyang Technological University, Singapore (NTU Singapore) have developed a cost effective, environment-friendly method to extract chitin from prawn shells and discarded fruit waste, through natural fermentation process. Chitin serves a wide variety of uses in the food industry, such as food thickeners and stabilisers, and as antimicrobial food packaging. NTU method of extracting chitin is more sustainable and creates high-quality chitin using accumulated crustacean waste, reducing overall waste. NTU research team also found they could ferment chitin further into chitosan, which can be used as a growth enhancer in plant fertilisers, or as a controlled drug delivery system in pharmaceutical treatments. They are also exploring ways to use chitosan which can potentially lead to the development of a more durable cellulose film with anti-microbial and anti-bacterial properties.

A blueprint for future weather system observation
A joint India-U.K. research project, has found that large-scale weather events such as monsoons and tropical cyclones can now be more accurately predicted. The findings show that oceanic processes play a crucial role in monsoon development through modulation of sea surface temperature (SST). The researchers created a blueprint for future weather system observational experiments, critical for forecasting aspects like rainfall amounts using a research vessel in the southern Bay of Bengal. They calculated time series of oceanographic properties, including temperature, salinity, velocity, underwater radiation and subsurface mixing, along with surface fluxes of heat, from shipboard measurements during the boreal summer monsoon of 2016. The study in the Bay of Bengal serves as a blueprint for future observational campaigns that aim to determine the processes that affect the variability of SST and its impact on weather systems.

JNCASR scientists fabricate energy-efficient photodetector for security application
Scientists from Jawaharlal Nehru Centre for Advanced Scientific Research (JNCASR) have fabricated an economical and energy-efficient wafer-scale photodetector (thin slice-based) using a gold (Au) – silicon (n-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. Being a solution-based technique, the method is highly economical and enables large-area fabrication without compromising the detector response. The process is quick, taking only minutes to fabricate a detector of any arbitrary area. With a commonly available protective coating, excellent environmental stability is shown for the device under the harsh conditions for several days.

Styrene gas leak: NGT slaps interim penalty of Rs 500 million on LG Polymers
Leakage of hazardous gas, Styrene, took place on May 7 at 0230 hrs from a chemical factory owned by the South Korean company LG Polymers India Pvt Ltd, at R.R. Venkatpuram village, near Vishakhapatnam, resulting in the death of 11 persons and over 1000 persons exposed. The major early morning chemical leak impacted villages in a five-km radius, leaving many people dead and scores of citizens suffering from breathlessness and other problems. The leak was noticed by company staff who were reportedly inspecting machines to restart the factory and raised an alarm. Following the incident the National Green Tribunal (NGT) took up the matter suo moto and nas set up a 5-member Committee to probe the incident, and submit a report before the next hearing on May 18 and directed LG Polymers India Pvt Ltd to deposit an initial amount of Rs 500 million with the District Magistrate, Vishakhapatnam. The committee has to submit its report on the sequence of events, causes of failure and persons and authorities responsible, extent of damage to life among others.

Water-splitting module captures solar energy
Rice University researchers have created an efficient, low-cost device that splits water to produce hydrogen fuel. It integrates catalytic electrodes and perovskite solar cells that, when triggered by sunlight, produce electricity. The current flows to the catalysts that turn water into hydrogen and oxygen, with a sunlight-to-hydrogen efficiency as high as 6.7%. The system encapsulates the perovskite layer with a Surlyn (polymer) film. The patterned film allows sunlight to reach the solar cell while protecting it and serves as an insulator between the cells and the electrodes. Even when there's no sunlight, stored energy in the form of hydrogen and oxygen products can be used like a fuel cell to turn those fuels back into electricity. The researchers will continue to improve the encapsulation technique as well as the solar cells themselves to raise the efficiency of the modules.
'Microscope on a chip' could bring medical expertise to distant patients
Researchers from the University of Barcelona, Spain are developing ChipScope, a device potentially compact enough to fit in a pocket. It may be possible for a modified mobile phone to have images of the nano-world. ChipScope which seeks to go beyond the optical diffraction limit and with no need of altering the sample. ChipScope's prototype illuminates a tissue sample using an array of minute (50 nanometres in size) light emitting diodes (LEDs)—to create shadow images of the specimen. These images are then captured using a detector sensitive enough to detect single photons and processed to produce a complete picture. Through very precise control of these tiny LEDs, the ChipScope imaging system has a spatial resolution of just below 200 nanometres—which is the usual limit with visible light. By triggering these tiny LEDs individually, and in sequence, the shadow images can be added to build up a picture of the sample. |

AOSIS Forum Calls for “Year of Ambition” on Climate Action
In an effort to ensure momentum on climate action despite the COVID-19 pandemic, the Alliance of Small Island States (AOSIS) convened the Placencia Ambition Forum virtually from 20-22 April 2020, hosted by the Government of Belize, currently serving as AOSIS Chair. The Forum resulted in a Declaration titled, ‘2020 – Our Year of Ambition,’ which calls for: (1) ambitious, detailed, new or updated nationally determined contributions (NDCs) that will close the gap between where we are now and where we need to be to limit global warming to 1.5°C; (2)new financial commitments that deliver on support and reflect ambition, including deeper discussions at COP 26 on the long-term finance goal to provide certainty for more ambitious mid- to long-term climate actions; and (3) enhanced near-term action to protect the vulnerable, including short-term action and domestic reform within the context of building long-term resilience. The Declaration also urges countries to follow through with COVID-19 recovery plans that incorporate policies and measures that help jump start NDC implementation and lead to enhanced ambition and action. It calls for a ‘Roadmap for Political Momentum’ towards COP 26, and welcomes the Group of 20 (G20) commitment to use the SDGs and other international commitments to guide recovery from COVID-19.The Declaration calls for 2020 to be “the year of ambition,” beginning with plans to change emission trajectories towards achieving 1.5°C.
