New York, Researchers, including an Indian-origin, have identified an advanced nanomaterial-based biosensing platform that detects, within seconds, <keyword id="102007" type="TECHNOLOGY" weightage="20" keywordseo="Antibodies">antibodies</keyword> specific to SARS-CoV-2, the <keyword id="9552202" type="UNKNOWN" weightage="20" keywordseo="virus-responsible">virus responsible</keyword> for the Covid-19 pandemic. In addition to testing, the platform will help to quantify patient <keyword id="1441458" type="DOMAIN" weightage="20" keywordseo="immunological">immunological</keyword> response to the new vaccines with precision, according to a paper published in the journal <keyword id="712433" type="ORGANIZATION" weightage="20" keywordseo="Advanced-Materials">Advanced Materials</keyword>. "We utilized the latest advances in materials and manufacturing such as nanoparticle 3D printing to create a device that rapidly detects Covid-19 antibodies," said researcher Rahul Panat, Associate Professor at Carnegie Mellon University in the US. The testing platform identifies the presence of two of the virus' antibodies, spike S1 protein and receptor-binding domain (RBD), in a very small drop of blood (about 5 microliters). Antibody concentrations can be extremely low and still detected below one picomolar (0.15 nanograms per millilitre). This detection happens through an <keyword id="10568667" type="UNKNOWN" weightage="20" keywordseo="electrochemical-reaction">electrochemical reaction</keyword> within a handheld microfluidic device which sends <keyword id="6402403" type="UNKNOWN" weightage="20" keywordseo="results">results</keyword> almost immediately to a simple interface on a smartphone. According to the researchers, an additive manufacturing technology called aerosol jet 3D printing is responsible for the efficiency and accuracy of the testing platform. Tiny, inexpensive gold micropillar electrodes are printed at the nanoscale using aerosol droplets that are thermally sintered together. This causes a rough, irregular surface that provides an increased surface area of the micropillars and an enhanced electrochemical reaction, where antibodies can latch on to antigens coated on the electrode. The specific geometry allows the micropillars to load more proteins for detection, resulting in very accurate, quick results. The test has a very low error rate because the binding reaction between the antibody and antigen used in the device is highly selective. The researchers were able to exploit this natural design to their advantage. The results come at an urgent time during the Covid-19 pandemic. "Because our technique can quantify the immune response to vaccination, it is very relevant in the current environment," Panat said.

For over a decade, researchers led by Andrew Sweetman of the Scottish Association for Marine Science (SAMS) encountered perplexing data indicating the presence of oxygen in this lightless environment. Initially dismissing these findings as sensor errors, the team eventually confirmed that the oxygen was indeed real and originating from the nodules themselves. <div type="Article" hostid="261" msid="112655642" title="&amp;#39;Alien: Romulus&amp;#39; director Fede Álvarez said he had to fight Disney to keep its extreme ending" mstype="2" mssubtype="0"></div>The key to this process lies in the electrochemical properties of the polymetallic nodules. These nodules, composed of metals like cobalt, nickel, and manganese, act like "geobatteries" capable of generating small electrical currents through a process called seawater electrolysis. This reaction splits water molecules, producing both hydrogen and oxygen. The voltage required is minimal — comparable to that of a standard AA battery — but when nodules are clustered together, their collective energy is sufficient to produce significant amounts of oxygen. <h3 style="line-height:1.2;margin-top:14pt;margin-bottom:4pt;">Implications for <keyword id="20144488" type="General" weightage="100" keywordseo="alien-life" source="keywords">alien life</keyword></h3>This discovery has profound implications for the search for extraterrestrial life. Previously, the existence of oxygen was considered a strong indicator of photosynthetic life forms. However, if oxygen can be produced in such an unconventional and lightless environment on Earth, it opens the door to the possibility that similar processes might occur on other celestial bodies with comparable conditions. This raises the tantalising prospect that life — or at least oxygen production — could exist on planets or moons without the need for sunlight. <div type="Article" hostid="261" msid="112860594" title="Space startup Reflect Orbital plans to sell &amp;quot;sunlight on demand&amp;quot; — how will it work?" mstype="2" mssubtype="0"></div>While the discovery is thrilling, it also presents challenges, particularly in the context of deep-sea mining. As industries look to exploit the mineral wealth of the ocean floor, there's now a pressing need to consider the environmental impact of such activities. The destruction of these oxygen-producing nodules could have severe consequences for <keyword id="22965693" type="General" weightage="20" keywordseo="deep-sea-ecosystems" source="keywords">deep-sea ecosystems</keyword>, potentially creating more "dead zones" where life struggles to recover.

The 36-year-old company — that has a market cap of over ₹12,000 crore — would infuse $5 million in the Bengaluru-based startup as a part of this deal. The deal is a part of the battery giant’s 'Energy and Mobility' strategy to enter new green technologies and solutions. “This will mark the first in a series of interesting developments that we plan to execute in the future. In this fast-changing technology landscape, we do not believe in a ‘one-size-fits-all’ approach and we are convinced that there will be the scope for interplay of multiple technology solutions for various applications,” Vikramadithya Gourineni, executive director at ARBL, said. The rest $3.5 million in <keyword id="11821909" type="UNKNOWN" weightage="20" keywordseo="log-9-material">Log 9 Material</keyword>’s Series A round was infused by both new and old investors, including AC Ventures, Exfinity Ventures and Sequoia Capital India’s accelerator programme Surge. Blackbuck’s cofounders Rajesh Yabaji and Chanakya Hridaya, Premji Invest’s partner Rajesh Ramaiah, Equinor’s Desikan Sundarajan and Emirates Investment Authority’s Faiz Mayalakkara also participated in the round. Founded by Akshay Singhal in 2015 at Indian Institute of Technology (IIT) Roorkee’s incubation centre TIDES, Log 9 Materials is a deeptech startup that focuses on battery technology for electric vehicles as well as other appliances. The company plans to use this latest funding to expand its production capacity and business development efforts for the latest innovation, <keyword id="11821911" type="UNKNOWN" weightage="20" keywordseo="rapid-charging-battery">Rapid Charging Battery</keyword> technology. The latest technology has completed its pilots successfully and will be rolled out for commercial use in October 2021. A part of the capital would also be used to advance other innovations like supercapacitor and aluminum fuel cell-based innovations. Supercapacitors are electrochemical energy storage devices that use power from the product/vehicle itself to power it. For instance, a supercapacitor would capture energy generated when a bus brakes and use it to start the bus again. Aluminium fuel cells are aluminium-air batteries (AI-air batteries) that produce electricity from oxygen and aluminium reactions.

<div class="image-container float_right" style="width:400px"><div class="image"></div><keyword id="6355174" type="CITY" weightage="60" keywordseo="Ford">Ford</keyword> Motor CompanyFord's Raj Nair, <keyword id="128620" type="CITY" weightage="60" keywordseo="Daimler-AG">Daimler AG</keyword>'s Thomas Weber, and <keyword id="46283" type="CITY" weightage="60" keywordseo="Nissan">Nissan</keyword>'s Mitsuhiko Yamashita.</div>Ford, Daimler AG (which owns Mercedes-Benz and Smart), and Renault-Nissan announced a partnership yesterday to speed up the development of zero-emission fuel cell electric vehicles by sharing the costs of investment.
Fuel cell electric vehicles (FCEVs) use electro-chemical reactions between hydrogen and oxygen to generate electricity, producing only water vapor and heat as by-products.
BMW and Toyota are <a href="http://www.businessinsider.com/bmw-hydrogen-fuel-cell-car-toyota-tech-2013-1">on the verge of finalizing their own deal</a> to work together on FCEVs.
Technology-sharing deals like these are common in an industry where the costs of developing new technology are very high. While each automaker will face more competition in selling its own FCEV, each will benefit from a more developed market and infrastructure.
Genevieve Cullen, vice-president of the <a href="http://www.electricdrive.org/">Electric Drive Transportation Association</a>, called the deal a "good and important step," and a sign that the automakers are committed to commercialization of FCEVs. The move into the field by Ford, Daimler AG, and Nissan will "create a big wake," she said.
The technology behind fuel cell <keyword id="20632" type="ORGANIZATION" weightage="60" keywordseo="Cars">cars</keyword> is undeveloped compared to that of hybrid and electric vehicles, but cars pumping out only water could be on the road by 2017, Cullen said. This new deal should make that target more attainable.
In a joint press release, the automakers said their collaboration "sends a clear signal to suppliers, policymakers and the industry to encourage further development of hydrogen refuel stations and other infrastructure necessary to allow the vehicles to be mass-marketed."
The biggest benefit may be standardization: Because all the FCEVs from the three automakers will use the same fuel cell system, the production of that system will be more cost-effective than if it worked for fewer cars.
The deal should also encourage more, necessary research. The <a href="http://www.ucsusa.org/clean_vehicles/smart-transportation-solutions/advanced-vehicle-technologies/fuel-cell-cars/fuel-cell-vehicles.html">Union of Concerned Scientists notes</a> that pure hydrogen gas does not occur in nature in concentrated amounts. Methods for producing hydrogen (extracting it from sources like natural gas and coal) exist, but more work is needed to find way to produce it from renewable resources.
Such research is more likely to move forward if three large companies will benefit from it, and the automakers know it.
And that's the point of the collaboration: The promise of three big companies to produce fuel cell electric vehicles could be enough to bring to life the infrastructure and market for those vehicles.
