Technology News ,China :- In a groundbreaking development, China has initiated trial runs for the world largest coal-based ethanol production plant in southeastern China, according to state media. This innovative facility, situated in Huaibei, Anhui province, boasts an impressive annual capacity of 600,000 tonnes and utilizes coal, rather than traditional crops, as the primary raw material for ethanol production.The shift to coal-based ethanol production is poised to alleviate the strain on China food resources while simultaneously reducing its reliance on imported fuel ethanol. Ethanol, a clean and renewable energy source with a density similar to petrol, serves as a valuable petrol additive and basic chemical.The Chinese Academy of Sciences Dalian Institute of Chemical Physics (DICP) emphasizes the significance of this new production route for China food security, energy security, and the chemical industry supply chain. Traditional ethanol production methods often compete with food supplies, making the utilization of low-grade coal—a resource abundantly available in China—an environmentally friendly alternative that could save millions of tonnes of grain annually.The coal-based plant in Huaibei relies on advanced technology jointly developed by DICP and the state-owned Shaanxi Yanchang Petroleum Group. Referred to as DMTE, the innovative technology produces methanol from coke oven gas, a by-product of coke production. This methanol then reacts with other materials to generate ethanol. Remarkably, DMTE technology is versatile enough to enable large-scale ethanol production not only from coal but also from natural gas or gas derived from steel plants.China stands alone as the only country to have deployed this technology on an industrial scale, marking a significant milestone in its commitment to sustainable energy practices.Ethanol, with its clean energy attributes, can be transformed into ethylene or replace ethylene in certain reactions as a chemical feedstock. This dual functionality positions ethanol as both an excellent energy product and a bulk chemical raw material, capable of producing a myriad of related products.Despite a significant demand for fuel ethanol in China, the country faces a considerable shortfall. Last year, it produced around 2.7 million tonnes of fuel ethanol through the fermentation of aged grain. However, a substantial market gap of 10 million tonnes necessitated heavy reliance on imports.The coal-to-ethanol team, led by DICP director Liu Zhongmin, has been at the forefront of environmentally friendly DMTE pathway research since 2010. The team previously designed the world first 100,000-tonne coal-to-ethanol production line in 2017, located in northwestern Shaanxi province. Over the years, they have optimized the reaction process and reduced production costs, achieving international standards in coal-to-ethanol production.With 13 industrial facilities, including two overseas ones, planning to adopt DMTE technology, the total ethanol production capacity is set to reach an impressive 3.95 million tonnes per year, marking a significant leap toward sustainable and domestically sourced fuel production.

Space News ,India :- ISRO has recently concluded another phase of testing for its Scramjet engine, marking a significant milestone in the development of air-breathing propulsion technology. In an earlier phase, the engine was tested with Hydrogen as fuel, and the recent tests involved the use of Kerosene (Isroscene) as fuel. This shift to Kerosene is notable for its ability to reduce overall volume, making it more suitable for extended-duration flights.Presently, satellite launch vehicles are typically expendable, designed for one-time use. These vehicles carry both fuel and oxidizer for combustion, resulting in high costs and low efficiency, as they can only transport a small percentage of their lift-off mass to orbit. To address this, there is a global effort to reduce launch costs, and one key focus is on developing next-generation launch vehicles with air-breathing propulsion systems.Approximately 70% of the propellant carried by current launch vehicles consists of oxidizer. Future launch vehicles need a propulsion system that can utilize atmospheric oxygen during flight, significantly reducing the total propellant required to place satellites in orbit. Additionally, making these vehicles reusable could further slash the cost of satellite launches.The concept of a reusable launch vehicle combined with air-breathing propulsion is gaining traction as a promising approach to achieving routine and cost-effective access to space. The development of air-breathing engines, including Ramjet, Scramjet, and Dual Mode Ramjet (DMRJ), is a strategic focus for space agencies worldwide.Ramjets utilize the vehicle forward motion to compress incoming air for combustion without a rotating compressor. They are most efficient at supersonic speeds but start to lose efficiency at hypersonic speeds. Scramjet engines, on the other hand, operate efficiently at hypersonic speeds, allowing supersonic combustion. The Dual Mode Ramjet (DMRJ) is a hybrid engine that transforms from a ramjet to a scramjet over a specific speed range, making it versatile for subsonic and supersonic combustor modes.In a significant achievement for ISRO, the successful flight testing of its Scramjet Engine Technology Demonstrator took place on August 28, 2016. This marked a crucial step towards realizing an Air Breathing Propulsion System. The test involved the use of the Scramjet engine at hypersonic speeds, reaching Mach 6, with the engine designed to use Hydrogen as fuel and atmospheric oxygen as the oxidizer. The testing utilized ISRO Advanced Technology Vehicle (ATV), a two-stage spin-stabilized launcher with identical solid motors. The Scramjet engines were mounted on the second stage, and after reaching the desired conditions for engine start-up, they functioned for about 5 seconds.ISRO successfully tackled various technological challenges during the development of the Scramjet engine, including designing a hypersonic engine air intake, developing a supersonic combustor, creating materials capable of withstanding high temperatures, simulating hypersonic flow with computational tools, ensuring engine performance across a wide range of flight speeds, managing thermal issues, and conducting extensive ground testing.India achievement in demonstrating the flight testing of a Scramjet Engine positions it as the fourth country globally to accomplish this significant milestone.

Technology News ,World :- Scientists have unveiled a groundbreaking method to combat cancer by harnessing the power of molecular jackhammers. Researchers from Rice University, Texas A&M University, and the University of Texas discovered that stimulating aminocyanine molecules with near-infrared light causes them to vibrate in unison, effectively rupturing the membranes of cancer cells.Aminocyanine molecules, commonly employed in bioimaging as synthetic dyes, have proven stability in water and are adept at binding to the exteriors of cells. In a significant advancement over previous cancer-killing molecular machines, such as Feringa-type motors, these molecular jackhammers exhibit mechanical motion over one million times faster and can be activated with near-infrared light instead of visible light, according to chemist James Tour from Rice University.The utilization of near-infrared light is pivotal as it facilitates deeper penetration into the body, potentially allowing the treatment of cancer in bones and organs without resorting to surgery. In experiments on cultured cancer cells, the molecular jackhammer approach achieved an impressive 99 percent success rate in destroying the cells. Furthermore, tests on mice with melanoma tumors resulted in half of the animals becoming cancer-free.The unique structure and chemical properties of aminocyanine molecules enable them to synchronize with the right stimulus, such as near-infrared light. When set in motion, the electrons within these molecules generate plasmons—collectively vibrating entities driving movement across the entire molecule.Chemist Ciceron Ayala-Orozco from Rice University emphasizes the significance of this discovery, highlighting that its the first instance of a molecular plasmon being utilized to excite the entire molecule and produce mechanical action to dismantle cancer cell membranes.The plasmons, equipped with an arm on one side, establish connections between the molecules and cancer cell membranes. The ensuing vibrations then contribute to breaking apart the membranes. While the research is still in its early stages, these initial findings hold great promise.The simplicity of this biomechanical technique also makes it challenging for cancer cells to develop effective defenses. Moving forward, researchers are exploring other types of molecules that can be employed in a similar fashion. In essence, this study represents a groundbreaking approach to cancer treatment, employing mechanical forces at the molecular scale to combat the disease.

Space News ,U.S :- In a significant achievement for the SARah reconnaissance system, two reflector satellites were effectively launched on December 24 from the Vandenberg Space Force Base in California, USA. The SpaceX Falcon 9 rocket, taking off from Launchpad SLC-4E at 14:11 CET, seamlessly deployed the two satellites into space within the scheduled 25-minute flight time. The initial signals from both satellites were promptly received, marking the commencement of the Launch and Early Orbit Phase (LEOP).During the LEOP, the SARah satellites undergo a meticulous system-by-system boot-up and functionality check, alongside precise maneuvers to position them in their designated orbits. The successful execution of this phase ensures the operational readiness of the reconnaissance system.Expressing relief and joy, the OHB project manager responsible for SARah conveyed, "It is a wonderful and relieving feeling to know that the two satellites are safely in orbit after all the hard work. The fact that we were able to experience this special moment today is a team effort and became possible thanks to the entire SARah team and the supporting colleagues from OHB."SARah stands as the successor to the SAR-Lupe system, which has served since 2007. OHB System AG, appointed as the prime contractor for SARah, collaborated with Airbus Defence and Space as a subcontractor to develop and construct three radar satellites for the mission. This includes a phased array satellite contributed by Airbus Defence and Space, and two identical reflector satellites, built on the proven technology of SAR-Lupe. This strategic combination harnesses the unique advantages of each satellite type, offering the German Armed Forces an enhanced global reconnaissance capability, irrespective of time of day or weather conditions.The Federal Ministry of Defence (Bundesministerium der Verteidigung, BMVg), represented by the Federal Office of Bundeswehr Equipment, Information Technology, and In-Service Support (Bundesamt für Ausrüstung, Informationstechnik und Nutzung der Bundeswehr, BAAINBw), is the esteemed customer for SARah.OHB System AG, in collaboration with OHB Digital Connect GmbH and Airbus Defence and Space, will be responsible for the ongoing operation of the SARah satellites, marking a pivotal moment in advancing Germany independent and sophisticated reconnaissance capabilities.

Technology News , World :- In a groundbreaking leap towards automated aviation, a routine cargo plane recently achieved a significant milestone by completing a 50-mile route sans human presence. The triumph, celebrated by Reliable Robotics, a California-based automation systems company, unfolded as a Cessna 208B Caravan seamlessly took off, navigated its course, and landed – all without a pilot on board.This remarkable 12-minute flight, originating from Hollister Airport in Northern California, saw a human pilot remotely steering the aircraft from a control center located 50 miles away, as per a press release from Reliable Robotics. The innovative flight system empowers the Cessna plane to be remotely operated by a ground-based pilot, offering a safeguard against in-flight control loss while enhancing safety during take-off and landing procedures.As reported by CNN, the pilot communicates with the aircraft through encrypted satellite signals, utilizing an interface akin to those used by air traffic controllers. Contrary to misconceptions, Robert Rose, CEO of Reliable Robotics, emphasized that the process is not akin to a video game, lacking a joystick or real-time video feedback. Instead, the pilot navigates the aircraft through a menu of options, resembling a "choose your own adventure" scenario with buttons facilitating redirection.Crucially, each communication sent during the flight incorporates landing instructions in the event of a communication failure in the future, ensuring an added layer of safety, according to CNN. Rose clarified that while the aircraft exhibits autonomous behavior, it merely follows the last directive given by humans in the absence of ongoing communication.Despite concerns among skeptics about the prospect of automated air control, aviation expert David Soucie reassured that the Reliable Robotics model does not intend to replace human pilots. Developed since 2019, the system may, however, play a pivotal role in addressing the ongoing shortage of pilots faced by airlines. Soucie explained to CNN that the automated flight model still necessitates a certified pilot to operate the plane from the cockpit, highlighting that it is not a standalone solution.In the face of a pilot shortage exacerbated by increased travel demand post-pandemic, the system could potentially alleviate the strain on airlines. While real-life pilots are still indispensable, the automated system enables them to work from a centralized location, reducing layovers and waiting times, as per Rose comments to CNN.Looking ahead, Reliable Robotics is collaborating with the US military to expand the application of this technology to larger aircraft, offering a glimpse into the future possibilities of automated aviation.
