Two MIT teams selected for NSF sustainable materials grants

New Post has been published on https://thedigitalinsider.com/two-mit-teams-selected-for-nsf-sustainable-materials-grants/

Two MIT teams selected for NSF sustainable materials grants

Two teams led by MIT researchers were selected in December 2023 by the U.S. National Science Foundation (NSF) Convergence Accelerator, a part of the TIP Directorate, to receive awards of $5 million each over three years, to pursue research aimed at helping to bring cutting-edge new sustainable materials and processes from the lab into practical, full-scale industrial production. The selection was made after 16 teams from around the country were chosen last year for one-year grants to develop detailed plans for further research aimed at solving problems of sustainability and scalability for advanced electronic products.

Of the two MIT-led teams chosen for this current round of funding, one team, Topological Electric, is led by Mingda Li, an associate professor in the Department of Nuclear Science and Engineering. This team will be finding pathways to scale up sustainable topological materials, which have the potential to revolutionize next-generation microelectronics by showing superior electronic performance, such as dissipationless states or high-frequency response. The other team, led by Anuradha Agarwal, a principal research scientist at MIT’s Materials Research Laboratory, will be focusing on developing new materials, devices, and manufacturing processes for microchips that minimize energy consumption using electronic-photonic integration, and that detect and avoid the toxic or scarce materials used in today’s production methods.

Scaling the use of topological materials

Li explains that some materials based on quantum effects have achieved successful transitions from lab curiosities to successful mass production, such as blue-light LEDs, and giant magnetorestance (GMR) devices used for magnetic data storage. But he says there are a variety of equally promising materials that have shown promise but have yet to make it into real-world applications.

“What we really wanted to achieve is to bring newer-generation quantum materials into technology and mass production, for the benefit of broader society,” he says. In particular, he says, “topological materials are really promising to do many different things.”

Topological materials are ones whose electronic properties are fundamentally protected against disturbance. For example, Li points to the fact that just in the last two years, it has been shown that some topological materials are even better electrical conductors than copper, which are typically used for the wires interconnecting electronic components. But unlike the blue-light LEDs or the GMR devices, which have been widely produced and deployed, when it comes to topological materials, “there’s no company, no startup, there’s really no business out there,” adds Tomas Palacios, the Clarence J. Lebel Professor in Electrical Engineering at MIT and co-principal investigator on Li’s team. Part of the reason is that many versions of such materials are studied “with a focus on fundamental exotic physical properties with little or no consideration on the sustainability aspects,” says Liang Fu, an MIT professor of physics and also a co-PI. Their team will be looking for alternative formulations that are more amenable to mass production.

One possible application of these topological materials is for detecting terahertz radiation, explains Keith Nelson, an MIT professor of chemistry and co-PI. This extremely high-frequency electronics can carry far more information than conventional radio or microwaves, but at present there are no mature electronic devices available that are scalable at this frequency range. “There’s a whole range of possibilities for topological materials” that could work at these frequencies, he says. In addition, he says, “we hope to demonstrate an entire prototype system like this in a single, very compact solid-state platform.”

Li says that among the many possible applications of topological devices for microelectronics devices of various kinds, “we don’t know which, exactly, will end up as a product, or will reach real industrial scaleup. That’s why this opportunity from NSF is like a bridge, which is precious, to allow us to dig deeper to unleash the true potential.”

In addition to Li, Palacios, Fu, and Nelson, the Topological Electric team includes Qiong Ma, assistant professor of physics in Boston College; Farnaz Niroui, assistant professor of electrical engineering and computer science at MIT; Susanne Stemmer, professor of materials at the University of California at Santa Barbara; Judy Cha, professor of materials science and engineering at Cornell University; industrial partners including IBM, Analog Devices, and Raytheon; and professional consultants. “We are taking this opportunity seriously,” Li says. “We really want to see if the topological materials are as good as we show in the lab when being scaled up, and how far we can push to broadly industrialize them.”

Toward sustainable microchip production and use

The microchips behind everything from smartphones to medical imaging are associated with a significant percentage of greenhouse gas emissions today, and every year the world produces more than 50 million metric tons of electronic waste, the equivalent of about 5,000 Eiffel Towers. Further, the data centers necessary for complex computations and huge amount of data transfer — think AI and on-demand video — are growing and will require 10 percent of the world’s electricity by 2030.

“The current microchip manufacturing supply chain, which includes production, distribution, and use, is neither scalable nor sustainable, and cannot continue. We must innovate our way out of this crisis,” says Agarwal.

The name of Agarwal’s team, FUTUR-IC, is a reference to the future of the integrated circuits, or chips, through a global alliance for sustainable microchip manufacturing. Says Agarwal, “We bring together stakeholders from industry, academia, and government to co-optimize across three dimensions: technology, ecology, and workforce. These were identified as key interrelated areas by some 140 stakeholders. With FUTUR-IC we aim to cut waste and CO2-equivalent emissions associated with electronics by 50 percent every 10 years.”

The market for microelectronics in the next decade is predicted to be on the order of a trillion dollars, but most of the manufacturing for the industry occurs only in limited geographical pockets around the world. FUTUR-IC aims to diversify and strengthen the supply chain for manufacturing and packaging of electronics. The alliance has 26 collaborators and is growing. Current external collaborators include the International Electronics Manufacturing Initiative (iNEMI), Tyndall National Institute, SEMI, Hewlett Packard Enterprise, Intel, and the Rochester Institute of Technology.

Agarwal leads FUTUR-IC in close collaboration with others, including, from MIT, Lionel Kimerling, the Thomas Lord Professor of Materials Science and Engineering; Elsa Olivetti, the Jerry McAfee Professor in Engineering; Randolph Kirchain, principal research scientist in the Materials Research Laboratory; and Greg Norris, director of MIT’s Sustainability and Health Initiative for NetPositive Enterprise (SHINE). All are affiliated with the Materials Research Laboratory. They are joined by Samuel Serna, an MIT visiting professor and assistant professor of physics at Bridgewater State University. Other key personnel include Sajan Saini, education director for the Initiative for Knowledge and Innovation in Manufacturing in MIT’s Department of Materials Science and Engineering; Peter O’Brien, a professor from Tyndall National Institute; and Shekhar Chandrashekhar, CEO of iNEMI.

“We expect the integration of electronics and photonics to revolutionize microchip manufacturing, enhancing efficiency, reducing energy consumption, and paving the way for unprecedented advancements in computing speed and data-processing capabilities,” says Serna, who is the co-lead on the project’s technology “vector.”

Common metrics for these efforts are needed, says Norris, co-lead for the ecology vector, adding, “The microchip industry must have transparent and open Life Cycle Assessment (LCA) models and data, which are being developed by FUTUR-IC.” This is especially important given that microelectronics production transcends industries. “Given the scale and scope of microelectronics, it is critical for the industry to lead in the transition to sustainable manufacture and use,” says Kirchain, another co-lead and the co-director of the Concrete Sustainability Hub at MIT. To bring about this cross-fertilization, co-lead Olivetti, also co-director of the MIT Climate and Sustainability Consortium (MCSC), will collaborate with FUTUR-IC to enhance the benefits from microchip recycling, leveraging the learning across industries.

Saini, the co-lead for the workforce vector, stresses the need for agility. “With a workforce that adapts to a practice of continuous upskilling, we can help increase the robustness of the chip-manufacturing supply chain, and validate a new design for a sustainability curriculum,” he says.

“We have become accustomed to the benefits forged by the exponential growth of microelectronic technology performance and market size,” says Kimerling, who is also director of MIT’s Materials Research Laboratory and co-director of the MIT Microphotonics Center. “The ecological impact of this growth in terms of materials use, energy consumption and end-of-life disposal has begun to push back against this progress. We believe that concurrently engineered solutions for these three dimensions will build a common learning curve to power the next 40 years of progress in the semiconductor industry.”

The MIT teams are two of six that received awards addressing sustainable materials for global challenges through phase two of the NSF Convergence Accelerator program. Launched in 2019, the program targets solutions to especially compelling challenges at an accelerated pace by incorporating a multidisciplinary research approach.

Commercial Window Cleaning Services Melbourne

Commercial window cleaning Services Melbourne is an essential part of keeping your business looking great. This is especially true for retail locations, where customers are constantly walking past and noticing the state of your windows. Dirty and streaked windows give the impression that your business isn’t well-maintained, and can turn potential customers away. Clean windows make a much better impression, and also allow in more natural light, which can help your business look larger and brighter.

While cleaning windows may seem like a simple task, there is a lot of work that goes into making sure the job is done correctly. Professional cleaners use specialised tools and equipment to get the best results, including a ladder and harness to reach high-up windows. This ensures that the cleaner is safe and does not fall off the window. This can be especially important for large buildings, which often have multiple stories and require special equipment to access the windows.

The most common method of washing windows is using a hose with purified water. This water is then sprayed onto the windows, and is then wiped off with a squeegee or cloth. The squeegee is particularly important, as it removes any excess water and leaves the windows dry and streak-free. Ideally, the squeegee should be changed regularly to prevent the rubber blade from becoming dull.

Many commercial cleaning companies offer additional services, such as the upkeep of window screens, sills, and tracks. This helps to ensure that the windows stay in good condition for as long as possible, and is an excellent way to increase the life of your windows. Some companies also offer a pressure cleaning service, which is useful for removing dirt from hard-to-reach areas.

Some businesses, such as restaurants and hotels, have specific cleaning requirements that must be met. These requirements may include the cleaning of specific windows, or the use of a specific type of cleaning agent. These types of requirements can be difficult to meet on your own, so it is usually best to hire a professional cleaner to do the job.

Whether you need your windows cleaned in a shopfront, office building, school, restaurant or hotel, Paul’s Window Washing can provide the highest-quality service. Their experienced team is fully insured and OH&S trained, and will work to your requirements to leave you with sparkling, streak-free windows.

With sustainable cement, startup aims to eliminate gigatons of CO₂

New Post has been published on https://thedigitalinsider.com/with-sustainable-cement-startup-aims-to-eliminate-gigatons-of-co%e2%82%82/

With sustainable cement, startup aims to eliminate gigatons of CO₂

While today’s cement is made through extremely high temperatures in a kiln, ancient Romans didn’t have that option. Still, anyone who’s been to Rome recently will tell you that ancient cement seems to have held up just fine.

The startup Sublime Systems thinks the Romans were onto something. The MIT spinout has created a drop-in replacement for today’s most commonly used cement, known as portland cement, that uses electrochemistry to skip the ultrahigh temperatures of conventional production — and the immense carbon dioxide emissions that go with it.

“Romans couldn’t go to those obscene temperatures, but they’ve proven their cement is hard and durable, and we now have 2,000 years of innovation to get that cement to meet the criteria we expect out of modern cement,” explains Sublime co-founder and CEO Leah Ellis, who developed the approach as a postdoc in the lab of Sublime co-founder and MIT Professor Yet-Ming Chiang.

Sublime’s approach has potential to make a major dent in global greenhouse gas emissions. The International Energy Agency estimates that cement is responsible for about 7 percent of human-driven carbon dioxide emissions worldwide. Sublime’s process eliminates emissions by foregoing the high temperatures and the use of limestone, which is nearly 50 percent CO₂ by weight, in favor of a novel electrochemical process.

“Cement enabled civilization as we know it today, but now it needs to be reinvented,” says Chiang, who is MIT’s Kyocera Professor of Ceramics. “Cement creates about 4 gigatons of emissions a year, and by 2050 that’s projected to become 6 gigatons a year. I think of what we’re doing as technically a very feasible way of decreasing those 4 gigatons of cement emissions as soon as possible.”

In May, Sublime reached a major milestone when 3 tons of its cement was poured in Boston’s largest net-zero commercial building in the Seaport district. Now the company is building a commercial-scale manufacturing plant in Holyoke, Massachusetts, that will be able to produce 30,000 tons of cement per year. The new plant is slated to come online as early as 2026.

“The Holyoke plant is designed to be a module that we can repeat to get to a million-ton-per-year plant,” Ellis says. “That will allow us to eliminate scale up risk so we can deploy simultaneously all over the world.”

From batteries to cement

Ellis came to MIT in 2018 as a postdoc after receiving a fellowship from the Canadian government to study anywhere she wanted.

“I chose to work with Yet-Ming Chiang in part because he has a great track record of being really creative and useful with the work he does in science,” Ellis says. “That’s the type of work I wanted: to discover things and push limits and solve problems.”

Although they were both experts in batteries, Ellis embraced Chiang’s suggestion of working on something different, and Chiang suggested exploring ways of using electrochemistry to make cement production more sustainable.

“Cement is the largest CO₂ emitter in the industrial materials world, and concrete is the world’s most abundant material by volume, next to water, but it hadn’t gotten a lot of attention on how its production could be electrified,” Chiang says.

Ellis and a graduate student, Andres Blades, began reviewing the literature on cement chemistry and production, looking for a more sustainable manufacturing process that might benefit from the rise of cheap, renewable electricity. Her research moved from exploring fundamental chemistry and technological approaches to economic and industry analyses.

“My motto is just to try as hard as I can for as long as they’ll let me,” Ellis says. “I strove to make myself indispensable. We started talking to customers and really understanding the industry and what they needed to see from low-carbon cement, what their concerns were, what the regulatory landscape was like, and it just has evolved from there. I really haven’t stopped since.”

Once the founders decided their approach had potential, they published the research in Proceedings of the National Academy of Sciences and launched their company in March of 2020. Working through Covid-19 disruptions, the team licensed their patent filings from MIT’s Technology Licensing Office and participated in the MIT i-Corps program, which helps scientific founders talk to potential customers.

“MIT has so many resources,” Ellis says. “It’s a real intellectual playground, and that makes it easy to start something up. There’s no textbook way to start up a company; it’s a game of constant exploration, and there’s so much available to explore at MIT.”

At the core of portland cement’s huge carbon footprint is the use of limestone, which is nearly 50 percent CO₂ by weight. Nearly all that CO₂ is released when limestone is heated to high temperatures to create lime. The heating process also creates enormous amounts of CO₂ on its own, as it requires temperatures of 1,450 C, a temperature that is difficult to electrify efficiently.

At MIT, Sublime’s team created an electrochemical process in which it breaks down calcium silicate rocks at ambient temperature using electrochemistry. The reaction works with abundant raw materials and creates reactive calcium and silicates that are dried and blended into Sublime’s cement.

The mixture has the same final strength and hardened phases as portland cement and meets a standard performance specification in the industry that allows it to be used in building construction.

“To our knowledge, we are the only true-zero solution for manufacturing a drop-in replacement for portland cement, because we don’t use fossil fuels and we don’t use limestone, so we can avoid all of the emissions from making portland cement,” Ellis says.

Changing the way we build

At an event hosted by MIT Technology Review a few years ago, WS Development senior vice president Yanni Tsipis ’01 SM ’02 heard about Sublime’s process and reached out to learn more. The conversation led to Sublime’s first commercial pour earlier this year in the biggest net-zero office building in Boston.

“We hope our partnership with Sublime illustrates the power of the possible when new technology flows from incubator to industry,” Tsipis says. “The location in the building’s primary public space will be experienced by thousands of people every day and is an ideal way to share our aspiration and Sublime’s extraordinary technology with the entire innovation ecosystem in Boston’s Seaport and beyond.”

Sublime is one of several companies Chiang has founded since he joined MIT as a professor nearly 40 years ago. Chiang, who also serves on the climate search advisory committee as part of MIT President Sally Kornbluth’s Climate Project at MIT, believes Sublime’s journey exemplifies the power of MIT’s community to advance impactful new technologies.

“Sublime came from recognizing a problem where there’s clearly an unmet need, and getting on it early when others hadn’t yet recognized its importance, then moving quickly to a solution that you can scale with speed to mitigate climate change,” Chiang says. “This is all just very MIT to me. We really want to focus on doing things that matter — not just to other academics, but to society and to the world.”

Concrete Cleaning Brisbane

Concrete forms the basis of any structure because of its sturdiness. If it is indoors the concrete is covered with paint or other materials. But the exterior of a structure is often left bare. This can accumulate dust and dirt and other weather-related organics such as moss over time.

Pressure cleaning is the best way to clean concrete surfaces, especially in large areas. Be it with air or with water, the pressure ensures that the deepest pores and crevices in the concrete are cleaned. The equipment used by the team from Ecoblast Pressure Cleaning Services is made from the latest technology. These will ensure that your concrete areas are cleaned without causing any damage to the surfaces, ensuring you have a clean and neat surrounding.
