Powering Ahead: Nobel-Winning Chemistry Unleashes Next-Generation Energy Storage Devices

Posted by in categories: chemistry, energy, sustainability, transportation

Flexible polymers made with a new generation of the Nobel-winning “click chemistry” reaction find use in capacitors and other applications.

Society’s increasing demand for high-voltage electrical technologies – including pulsed power systems, cars, electrified aircraft, and renewable energy applications – requires a new generation of capacitors that store and deliver large amounts of energy under intense thermal and electrical conditions.

A new polymer-based device that efficiently handles record amounts of energy while withstanding extreme temperatures and electric fields has now been developed by researchers at the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) and Scripps Research. The device is composed of materials synthesized via a next-generation version of the chemical reaction for which three scientists won the 2022 Nobel Prize in Chemistry.

Making big leaps in understanding nanoscale gaps

Posted by in categories: chemistry, nanotechnology, physics, solar power, sustainability

Creating novel materials by combining layers with unique, beneficial properties seems like a fairly intuitive process—stack up the materials and stack up the benefits. This isn’t always the case, however. Not every material will allow energy to travel through it the same way, making the benefits of one material come at the cost of another.

Using cutting-edge tools, scientists at the Center for Functional Nanomaterials (CFN), a U.S. Department of Energy (DOE) User Facility at Brookhaven National Laboratory, and the Institute of Experimental Physics at the University of Warsaw have created a new layered structure with 2D materials that exhibits a unique transfer of energy and charge. Understanding its may lead to advancements in technologies such as solar cells and other optoelectronic devices. The results were published in the journal Nano Letters.

Transition metal dichalcogenides (TMDs) are a class of materials structured like sandwiches with . The meat of a TMD is a , which can form with electrons on their outermost orbit or shell, like most elements, as well as the next shell. That metal is sandwiched between two layers of chalcogens, a category of elements that contains oxygen, sulfur, and selenium.

How “Smart Rust” Nanoparticles Are Revolutionizing Water Cleanup

Posted by in categories: nanotechnology, particle physics, sustainability

Researchers have developed “smart rust,” iron oxide nanoparticles that clean water by attracting pollutants such as oil, nano-and microplastics, glyphosate, and even estrogen hormones.

Pouring flecks of rust into water typically makes it dirtier. However, a groundbreaking development by researchers has led to the creation of “smart rust,” a type of iron oxide nanoparticle that can purify water. This smart rust has the unique ability to attract various pollutants, such as oil, nano-and microplastics, and the herbicide glyphosate, depending on the particles’ coating. What makes it even more efficient is its magnetic nature, which allows easy removal from water using a magnet, taking the pollutants along with it. Recently, the team has optimized these particles to capture estrogen hormones, which can be detrimental to aquatic life.

Presentation and Significance.

First generation of zero-carbon emission aircraft needs hydrogen technologies by 2025

Posted by in categories: government, sustainability, transportation

Led by the Aerospace Technology Institute (ATI) and backed by the UK government, FlyZero has concluded that green liquid hydrogen is the optimum fuel for zero-carbon emission flight and could power a midsize aircraft with 280 passengers from London to San Francisco directly, or from London to Auckland with just one stop.

FlyZero, the UK study into zero-carbon emission commercial air travel, has published its vision for a new generation of aircraft powered by liquid hydrogen, today Thursday 17th March.

The report Our Vision for Zero-Carbon Emission Air Travel marks the conclusion of a 12-month study which set out to consider the feasibility of zero-carbon emission aircraft. The project concludes aviation can achieve net zero 2050 through the development of both sustainable aviation fuel (SAF) and green liquid hydrogen technologies.

THE HUMAN FUTURE: A Case for Optimism

Posted by in categories: climatology, media & arts, robotics/AI, sustainability

Soundtrack: Patreon: Change is coming. Humanity is entering a turbulent new era, unprecedented in both Earth and Human history. To survive the coming centuries and fulfill our potential as a species, we will have to overcome the biggest challenges we have ever faced, from extreme climate change, to rogue A.I., to the inevitable death of the sun itself.

The headlines make our chances look bleak. But when you look at our history and our tenacity, it’s clear that humanity is uniquely empowered to rise to the challenges we face.

Since 2015, reusable rockets have dramatically decreased the cost of transportation from Earth to orbit

Posted by in categories: space travel, sustainability

Such process is paving the path toward civilian space development and astropolitical uses of space as well, and is creating a growing interdependent relationship between life on and beyond Earth. 2015 can now be identified as a “turning point” in history, signifying a change of paradigm, from “traditional” aerospace to a “new space” age.

As soon as the U.N. 2030 Agenda [1] was published, some relevant criticalities appeared. The general criteria supporting the concept of sustainability developed by the agenda is an unquestioned limitation to the boundary of Earth’s atmosphere. The 2030 Agenda for Sustainable Development, adopted by all United Nations Member States in 2015, was conceptualized during the traditional aerospace age: outer space was not considered, as a dimension that helps to increase the sustainability of development. Space science and technologies are supporting social and environmental goals on Earth, for many years. Yet that will not be enough, to warrant a really sustainable development. To allow a real sustainable development, it is indispensable and urgent to start civilian space development, outside Earth boundaries. Therefore the UN 2030 Agenda of the Sustainable Development Goals needs to be updated.

Materials to feed the green energy revolution

Posted by in categories: chemistry, energy, engineering, sustainability

Dr Kathryn Mumford is an Associate Professor in the Department of Chemical Engineering at the University of Melbourne, specialising in separation processes in ion exchange, solvent absorption and solvent extraction technologies. In collaboration with industry, her recent research has pioneered a more efficient, greener process to produce lithium carbonate.

Dr Mumford leads the Sustainable Resources platform, which focuses on research to support the transition to green energy, reduce environmental impact and develop smart mining and processing. Here, she discusses how the platform is tackling the industry’s greatest challenges, and the role the sector will play in decarbonising the world.

I’ve been thinking about sustainability and environmental health throughout my whole career. I saw the consequence of waste and was compelled to develop ways to reduce its impact. My PhD was around environmental clean-up, specifically cleaning up tip sites and fuel spills at contaminated sites in Antarctica – I’ve since been back to Antarctica seven times on clean-up missions.
