British scientists have unlocked a game-changing solution to water scarcity by designing a graphene-based filter capable of turning seawater into safe, drinkable water almost instantly. Unlike traditional desalination systems that are expensive and energy-hungry, this lightweight filter uses advanced nanotechnology to remove salt and contaminants at the molecular level—with minimal power requirements. This breakthrough could revolutionize access to clean water in disaster zones, arid regions, and coastal communities where freshwater is scarce. It also opens the door to decentralized water infrastructure, where portable units can deliver clean water on demand without heavy logistics or massive plants.

Atomically thin semiconductors driving smart sensors with real-world impact Focusing on atomically thin semiconductors at RMIT University, we are creating the next generation of ultra-sensitive sensors and smart systems. They are smaller, faster, and more energy-efficient than ever before. Our innovation begins at the atomic scale. My colleagues and I are engineering two-dimensional (2D) semiconductors such as graphene, transition-metal dichalcogenides, and transition-metal oxides - materials only a few atoms thick yet possessing extraordinary electrical and optical tunability. These quantum-thin layers exhibit exceptional charge-carrier mobility, excitonic behaviour, and mechanical flexibility, unlocking new frontiers in wearable sensors, ultra-fast optoelectronics, and bio-integrated devices. I’m lucky to work in world-class research facilities, which serve as the backbone of innovation, enabling interdisciplinary collaboration across scales, and alongside several national research centres, including the ARC Centre of Excellence in Optical Microcombs for Breakthrough Science (COMBS) . These hubs help connect my research to a global network of experts in photonics, quantum materials, and low-energy electronics. What truly distinguishes our approach is the ability to translate atomic-scale discoveries into intelligent, connected systems. Atomically thin semiconductor devices are being integrated into Internet of Things platforms, wireless communication modules, and AI-assisted signal processors, creating systems that not only sense but also interpret and respond. These platforms enable real-time environmental monitoring, such as detecting trace gases and pollutants, as well as advanced biomedical diagnostics, where bio-field-effect transistors (bio-FETs) and photonic biosensors can identify disease biomarkers at early stages. In the energy and mobility sectors, high-mobility 2D semiconductors are driving low-power electronics and adaptive control systems for sustainable technologies. RMIT’s multidisciplinary engineering ecosystem ensures each layer, from material design to data analytics, contributes to intelligent functionality. A notable example of this multi-layered ecosystem at work is the world-first ingestible gas-sensing capsule, now commercialised by Atmo Biosciences. Incorporating nanoscale sensors, a smart processor, and a wireless transmission module, the capsule measures intestinal gases in vivo and transmits real-time data to reveal insights into gut health. It exemplifies how nanomaterial-enabled sensors can evolve into life-changing medical technologies. By uniting atomically thin materials, smart system integration, and global collaboration, my colleagues and I continue to lead in Electrical and Electronic Engineering research. We are shaping a future where every atom powers intelligent, sustainable, and connected technologies. Interested in collaborating? Get in touch: Jian Zhen Ou - RMIT University

A new #textile was designed to combat the urban heat island effect, reflecting both the sun’s heat and the heat bouncing off buildings and streets. When a heat wave hits a city, the sidewalks, roads, and buildings make the air feel hotter. Thanks to the urban heat island effect, all that infrastructure absorbs and reemits the sun’s heat, raising temperatures even more. Getting cool means protecting yourself not just from the sun’s radiation but also from all the radiation bouncing off the pavement and concrete. A new textile—made of plastic and silver nanowires—does that and can keep its wearers as much as 16 degrees cooler than other fabrics. This week, a heat wave is expected to stretch across much of the U.S., with particularly dangerous temperatures forecasted for cities such as #Chicago, #NewYork, and #Boston. This new textile could provide some relief. It uses a process called radiative cooling, which describes how objects cool down by radiating thermal energy into their surroundings. Radiative cooling textiles do already exist, but most just reflect the sun’s heat. That “works very well if you’re in an open field,” says Po-Chun Hsu, a molecular engineering professor at the University of Chicago, whose team recently published a paper on their new material in the journal Science. But not in a city. Existing fabrics don’t reflect the ambient heat from the street below or a nearby building. The heat coming directly from the sun’s rays and the heat emitted from a sun-baked street aren’t the same; they have different wavelengths. That means a material has to have two different “optical properties” to reflect both. To do that, the researchers created a three-layer textile. The top layer is made of polymethylpentene or PMP, a type of plastic commonly used for packaging; the researchers had to figure out how to spin it into a fiber. The second is a sheet of silver nanowires, which acts like a mirror to reflect infrared radiation. Together, these block both the solar radiation and the ambient radiation reflected off of surfaces. The third layer can be any conventional fabric, like wool or cotton. Though there are multiple layers, the main thickness comes from the conventional fabric; the top layer is about 1/100th of a human hair. In outdoor tests in Arizona, the textile stayed 4 degrees Fahrenheit cooler than “broadband emitter” fabrics used for outdoor sports and 16 F cooler than regular silk, a breathable fabric often used for dresses and shirts. Along with clothing, the researchers say this cooling textile could be used on buildings, in cars, or even for food storage and shipping in order to lessen the need for refrigeration, which has a significant climate impact of its own. Next, Hsu’s team is collaborating with other teams to see how the textile could have a health benefit for those in extreme heat conditions. #climatechange #apparel #brands #retail #technology Kristin Toussaint for Fast Company

Perhaps of interest -- our article, titled “Materials Advances for Distributed Environmental Sensor Networks at Scale,” just now published in Nature Reviews Materials (https://lnkd.in/g8UJZyym). This piece summarizes efforts to develop materials and device strategies for large-scale, multiparametric monitoring of environmental events – natural or anthropogenic. We believe that there are significant research opportunities for new engineering approaches in this area, oriented around adapting and extending advanced bioelectronic sensors of the health of an individual – a focus of ours and other groups worldwide – for spatio-temporal tracking of the health of an environment. For this envisioned use case, the challenges are not only in the sensors, but also in their cost-effective volume production, wide-scale rapid dispersal and long-range quantitative readout. Our recent papers (https://lnkd.in/g8FbcBhx  https://lnkd.in/gQfS-4aJ https://lnkd.in/gcnRN5Di) aim to achieve these goals through ideas in 3D assembly methods, eco-resorbable materials, optimized aerodynamic designs and digital imaging techniques -- as routes to large quantities of small-scale, environmentally benign colorimetric/electronic sensors with 3D architectures that enable passive flight via mechanisms inspired by wind-dispersed seeds. Our review article captures these and many other new concepts that show promise in this important field of research. As we write in our introduction: “The rapid increase in global human population and the ever-evolving landscape of modern industrialization place a mounting burden on the availability of natural resources, as well as on the health and stability of the ecosystems that support them.” The academic research community can play a central role in developing technologies to address these worrisome trends – and as a bonus, working on mobile collections of small, eco-resorbable, wireless sensors for the environment is tremendous fun! Thanks to Prof. Kenneth Madsen (former postdoc now on the faculty at Baylor University), Prof. Matthew Flavin (former postdoc now on the faculty at Georgia Institute of Technology) for leading the process of writing this article, and thanks to the editors for the invitation to contribute!

UK scientists at the University of Manchester have developed a graphene oxide-based membrane that can filter salt out of seawater, marking a significant advancement in desalination technology. This membrane operates by blocking salt ions while allowing water molecules to pass, making it a promising solution for fresh water generation. However, despite its groundbreaking potential, the system is still in the research and development phase and not yet capable of providing instant desalination at scale. Efforts are ongoing to improve the membrane's practicality for real-world use, especially in areas facing water scarcity.

In a groundbreaking achievement from Germany, scientists have developed a revolutionary graphene-based water filter that turns toxic industrial wastewater into drinkable water within seconds. Using only gravity and a layer of graphene oxide just a few nanometers thick, the filter blocks heavy metals, dyes, and microplastics, allowing only pure water molecules to pass. This invention represents a major leap forward in clean water access, powered entirely by advanced nanotechnology. The key lies in the atomic structure of graphene. The filter has pores designed at the angstrom level, which are precisely sized to reject everything except water molecules. Its surface is hydrophilic, meaning it naturally attracts water without requiring pressure, power, or chemicals. Field tests conducted near a textile factory in Germany proved that even wastewater contaminated with chromium and dye could be instantly purified to meet World Health Organization drinking water standards. Because the system operates on passive flow alone, it is entirely off-grid and highly portable. It can be scaled for use in rural communities, emergency zones, and large industrial sites alike. The membrane is also resistant to fouling, as its electrostatic properties prevent buildup and allow easy restoration with a simple rinse. If implemented on a global scale, this German innovation could deliver safe, affordable water to over two billion people, using cutting-edge science to meet one of the planet’s oldest needs. #water #savetheplanet
