Scientists are now planning to ‘grow’ ice and ‘refreeze’ Arctic Sea

Posted by in categories: climatology, sustainability

An innovative way is being created by scientists which will help them in “growing” ice and doing the impossible job of “refreezing” the Arctic Sea as initial tests prove promising.

Scientists are aiming at pumping seawater over the frozen Arctic Ocean. They have carried out trials in the Canadian Arctic which have seen sea ice getting thickened successfully.

According to a report published in New Scientist, if no action is taken right now, the accelerating climate change will make the Arctic “ice-free in the summer in the 2030s” which will be disastrous for the planet.

Engineers develop solar-powered lithium extraction from brine

Posted by in category: sustainability

A team of engineers at Nanjing University, working with a pair of colleagues from the University of California, Berkeley, has developed a new way to extract lithium from briny water.

In their paper published in the journal Science, the team describes the process they developed and the device they built and how it could be used to extract lithium from various natural sources. Seth Darling, with Argonne National Laboratory in the U.S., has published a Perspective piece in the same journal issue outlining the work done by the team on this new effort.

Lithium is in high demand due to its use in batteries. Unfortunately, its traditional sources, hard rock ores, are expected to decline in the coming years. Because of that, scientists have been looking for other sources like briny water found in the world’s oceans. Prior research has suggested there is more than enough to meet global demand for as long as needed.

Toyota unveils its secret and shocks the world: This engine is both combustion and zero-emission

Posted by in categories: energy, sustainability, transportation

In a surprise revelation, Toyota has sent shockwaves throughout the automotive world with an all-new engine that melds combustion technology with the potential for zero emissions. This stealth development may transform our thinking about green energy and the future of transportation. For two decades, the world has been struggling over what the road to sustainable transport would look like, and to date, EVs have proven a front-runner. However, Toyota’s latest development puts a monkey wrench into that thinking by suggesting that a hydrogen-powered combustion engine may be what carries us into the future.

While Toyota is no stranger to innovation—it gave the world its first mass-produced hybrid, the Prius, back in 1997—it has traditionally taken a more cautious approach toward anything resembling an electric vehicle. Less conservatively speaking, the hydrogen-powered combustion engine signifies a quantum leap. This latest motor technology is based on a variant of the same 1.6-liter turbocharged three-cylinder used in its GR Corolla and GR Yaris. Instead, it relies on hydrogen, not traditional gasoline, to run the engine, making it cleaner than conventional combustion engines.

This innovative engine could also hold the key to one of the most significant challenges for the car-making industry: balancing high performance with sustainability. While electric cars take away that visceral experience from driving enthusiasts, Toyota’s hydrogen engine ensures a gasoline-powered car’s rumble, response, and mechanical integrity. The company tested it thoroughly through the grueling conditions of motorsports, including endurance events such as the Fuji 24 Hours.

Carbon Fiber Structural Battery Paves way for Light, Energy-Efficient Vehicles

Posted by in categories: chemistry, computing, mobile phones, sustainability, transportation

When cars, planes, ships or computers are built from a material that functions as both a battery and a load-bearing structure, the weight and energy consumption are radically reduced. A research group at Chalmers University of Technology in Sweden is now presenting a world-leading advance in so-called massless energy storage — a structural battery that could halve the weight of a laptop, make the mobile phone as thin as a credit card or increase the driving range of an electric car by up to 70% on a single charge.

“We have succeeded in creating a battery made of carbon fiber composite that is as stiff as aluminum and energy-dense enough to be used commercially. Just like a human skeleton, the battery has several functions at the same time,” says Chalmers researcher Richa Chaudhary, who is the first author of an article recently published in Advanced Materials.

Research on structural batteries has been going on for many years at Chalmers, and in some stages also together with researchers at the KTH Royal Institute of Technology in Stockholm, Sweden. When Professor Leif Asp and colleagues published their first results in 2018 on how stiff, strong carbon fibers could store electrical energy chemically, the advance attracted massive attention.

New materials and techniques show promise for microelectronics and quantum technologies

Posted by in categories: computing, nanotechnology, particle physics, quantum physics, solar power, sustainability

The next generation of handheld devices requires a novel solution. Spintronics, or , is a revolutionary new field in condensed-matter physics that can increase the memory and logic processing capability of nano-electronic devices while reducing power consumption and production costs. This is accomplished by using inexpensive materials and the magnetic properties of an electron’s spin to perform memory and logic functions instead of using the flow of electron charge used in typical electronics.

New work by Florida State University scientists is propelling spintronics research forward.

Professors Biwu Ma in the Department of Chemistry and Biochemistry and Peng Xiong in the Department of Physics work with low-dimensional organic metal halide hybrids, a new class of hybrid materials that can power optoelectronic devices like solar cells, light-emitting diodes, or LEDs and photodetectors.

Report: Global drought threatens food supplies and energy production

Posted by in categories: energy, food, sustainability

In July 2024, global temperatures reached unprecedented levels, breaking historical records with an average of 17.16°C. This extreme heat has led soil water to evaporate, leaving the vegetation and biodiversity more fragile and under stress in many regions of the world.

Forecasting Change: The Future of Winter Weather in the 21st Century

Posted by in categories: climatology, computing, sustainability

How will climate change alter winter weather in the future? This is what a recent study published in npj Climate and Atmospheric Science hopes to address as a team of researchers investigated the long-term effects of climate change on winter weather precipitation, or wetness. This study has the potential to help researchers, climate scientists, policymakers, and the public understand the long-term consequences of global climate change and the steps that can be taken to mitigate it.

For the study, the researchers used computer models to compare precipitation levels between 1985 and 2014 and compared these to model-predicted data spanning from 2070 to 2099 across seven subregions across the United States. In the end, the researchers estimate an increase between 2 to 5 percent of precipitation for every degree increase before the end of the century, noting this increase will hit the Northwest and Northeast regions of the United States the hardest.

“We found that, unlike summer and other seasons where projected changes in precipitation is highly uncertain, there will be a robust future intensification of winter precipitation,” said Dr. Akintomide Akinsanola, who is an assistant professor in the Department of Earth and Environmental Sciences at the University of Illinois Chicago and lead author of the study. “It will accelerate well past what we have seen in historic data.”

Scientists develop a new model of electric double layer

Posted by in categories: sustainability, transportation

A new model accounts for a wide range of ion-electrode interactions and predicts a device’s ability to store electric charge. The model’s theoretical predictions align with the experimental results. Data on the behavior of the electric double layer (EDL) can aid in the development of more efficient supercapacitors for portable electronics and electric vehicles. The study has been published in ChemPhysChem.
