The demand for electronics has led to a significant increase in e-waste. In 2022, approximately 62 million tons of e-waste were generated, marking an 82% increase from 2010. Projections indicate that this figure could rise to 82 million tons by 2030.

E-waste contains valuable materials such as metals, semiconductors, and rare elements that can be reused. However, in 2022, only 22.3% of e-waste was properly collected and recycled, while the remaining materials, estimated to be worth almost $62 billion, were discarded in landfills.

Although efforts to improve e-waste recycling continue, the process remains labor-intensive, and a significant portion of e-waste is exported to developing countries, where cheap labor supports informal recycling practices involving hazardous chemicals.

A research team at the Institute of Materials Chemistry at TU Wien, led by Professor Dominik Eder, has developed a new synthetic approach to create durable, conductive and catalytically active hybrid framework materials for (photo)electrocatalytic water splitting. The study is published in Nature Communications.

The development of technologies for sustainable energy carriers, such as hydrogen, is essential. A promising way to produce hydrogen (H₂) is from splitting water into H₂ and oxygen (O₂), either electrochemically or using light, or both—a path that the team follows. However, this process requires a catalyst that accelerates the reaction without being consumed. Key criteria for a catalyst include a large surface area for the adsorption and splitting of water molecules, and durability for long-term use.

Zeolitic imidazolate frameworks (ZIFs), a class of hybrid organic/inorganic materials with molecular interfaces and numerous pores, offer record surface areas and ample adsorption sites for water as catalysts. They consist of single metal ions, such as cobalt ions, which are connected by specific organic molecules, called ligands, through what is called coordination bonds. Conventional ZIFs only contain a single type of organic ligand.

As a simple illustration, let’s say someone wanted to create a tomato sauce recipe, optimizing vitamin C and using sustainable tomatoes within a certain cost range. Journey Foods then taps into its database to generate an optimal recipe, and will continually push recommendations of top suppliers.

“Essentially, when people go to ChatGPT or something, and they’re asking them, ‘write this paper for me, or give me a social media post, speak to this audience,’ or whatever, right? It’s the same thing with our generative recipe recommendations,” Lynn said.

Except Lynn doesn’t use ChatGPT. Systems such as ChaptGPT gather data from the open internet, but Journey Foods gets its data from research institutions, academic journals, suppliers and manufacturers. Lynn said her business uses a lot of private, hard data that’s unstructured, with her company then giving it structure and doing so globally.

Pesticides can be made more effective and environmentally friendly by improving how they stick to plant surfaces, thanks to new research led by Dr. Mustafa Akbulut, professor of chemical engineering at Texas A&M University.

Akbulut and his research group have developed an innovative pesticide delivery system called nanopesticides. These tiny technologies, developed through a collaboration between Texas A&M University’s engineering and agricultural colleges, Dr. Luis Cisneros-Zevallo, professor of Horticultural Science and Dr. Younjin Min, professor of Chemical Environ Engineering at University of California, Riverside, could change how we use pesticides.

“The U.S. is a world leader in agricultural production, feeding not just our nation but much of the world. Yet we are using pesticides in a way that is simply not sustainable—with a substantial fraction not reaching its intended target,” said Akbulut. “Our research shows that by optimizing the surface chemistry of pesticide carriers, we can make these essential crop protection tools more efficient.”

The 300-acre circle in the middle of the desert is enigmatic: It is producing 500,000 MW. It is a solar energy and melts salt to produce electricity.

Readily available thermoelectric generators operating under modest temperature differences can power CO₂ conversion, according to a proof-of-concept study by chemists at the University of British Columbia (UBC).

The findings open up the intriguing possibility that the temperature differentials encountered in an array of environments—from a typical geothermal installation on Earth to the cold, desolate surface of Mars—could power the conversion of CO₂ into a range of useful fuels and chemicals.

“The environment on Mars really got me interested in the long-term potential of this technology combination,” says Dr. Abhishek Soni, postdoctoral research fellow at UBC and first author of the paper published in Device.

In the simplest terms, nearly every modern car on the planet uses disk brakes: a rotor attached to a hub with a caliper with brake pads fixed to the control arm at each wheel. The driver presses the brake pedal and hydraulic fluid is pushed down the brake lines into the caliper, expanding the pistons and pushing the brake pads against the rotor, slowing down the rotation of the rotor connected to the hub, thus slowing down the wheel.

There are other systems, like drum brakes, air brakes, band brakes, the Flintstones method, et cetera, that have also been around since the dawn of the automotive industry. The concept almost always remains the same: using friction to slow down. And so it doesn’t go unsaid, yes, there are compression brake systems as well, but that’s entirely different.

Mercedes-Benz has put a new spin on an age-old concept with what it calls “in-drive brakes” for electric vehicles. The system being developed at the company’s research and development department in Sindelfingen, Germany, integrates the brakes right into the drivetrain, in an arrangement that works very much like a transmission brake. It resembles clutch plates – but with a unique twist.

A photovoltaic paste under development could turn ordinary body panels into solar panels.

A study reveals that while levels of common contaminants are low, other elements are found in high concentrations in waters associated with an abandoned lithium mine.

A new study suggests that lithium ore and mining waste from a historic lithium mine west of Charlotte, North Carolina, are unlikely to pollute nearby waters with common contaminants like arsenic and lead.

However, high levels of other metals — namely, lithium, rubidium, and cesium — do occur in waters associated with the mine.
