Researchers at McGill University have made a significant advance in the development of all-solid-state lithium batteries, which are being pursued as the next step in electric vehicle (EV) battery technology.

By addressing a long-standing issue with battery performance, this innovation could pave the way for safer, longer-lasting EVs. The findings are published in the journal Cell Reports Physical Science.

The challenge lies in the resistance that occurs where the ceramic electrolyte meets the electrodes. This makes the battery less efficient and reduces how much energy it can deliver. The research team has discovered that creating a porous ceramic membrane, instead of the traditional dense plate, and filling it with a small amount of polymer can resolve this issue.

Pace of growth helps maintain renewable energy when weather conditions interfere with wind and solar.

1GITEX Global 2024 and IROS 2024 became true gateways to the future of technology, bringing together the most advanced innovations in artificial intelligence, robotics, and transportation under one roof. At the forefront of GITEX was the unique Nissan Hyperforce concept, an electric vehicle with an incredible 1,360 horsepower, capable of accelerating from 0 to 100 km/h in just 2 seconds. This electric supercar not only stunned with its speed but also with its futuristic design, reminiscent of the iconic Batmobile. With its advanced driving modes, R and GT, drivers can switch between a sporty and comfortable driving experience.

Researchers at Monash University have developed an artificial intelligence (AI) model that significantly improves the accuracy of four-dimensional scanning transmission electron microscopy (4D STEM) images.

Called unsupervised deep denoising, this model could be a game-changer for studying materials that are easily damaged during imaging, like those used in batteries and solar cells.

The research from Monash University’s School of Physics and Astronomy, and the Monash Center of Electron Microscopy, presents a novel machine learning method for denoising large electron microscopy datasets. The study was published in npj Computational Materials.

How much carbon dioxide (CO₂) do plants absorb from the atmosphere? This is what a recent study published in Nature hopes to address as a team of researchers investigated what’s known as the Terrestrial Gross Primary Product (GPP), which measures the amount of CO₂ that photosynthesis removes from the atmosphere. This study holds the potential to help researchers, climate scientists, legislators, and the public better understand the role that plants play in reducing carbon emissions, along with mitigating the effects of climate change worldwide.

“Figuring out how much CO₂ plants fix each year is a conundrum that scientists have been working on for a while,” said Dr. Lianhong Gu, who is a distinguished research scientist at the Oak Ridge National Laboratory (ORNL) and a co-author on the study. “The original estimate of 120 petagrams per year was established in the 1980s, and it stuck as we tried to figure out a new approach. It’s important that we get a good handle on global GPP since that initial land carbon uptake affects the rest of our representations of Earth’s carbon cycle.”

Petagrams are the standard measurement used for GPP, with one petagram equaling 1 billion metric tons, and the latter being the amount of CO₂ discharged from the total number of gas-powered passenger vehicles in the world, which is approximately 1.4 billion.

Sweden’s Alight and Finland’s 3Flash have entered into a joint development agreement to build a 120 MW solar park in Loviisa, a town in southeastern Finland.

Construction is expected to begin early next year, with commissioning currently scheduled for 2027. Once completed, it is expected to generate 155 GWh, equivalent to the annual electricity needs of 31,000 households.

HVAC systems common in data centers expel warm air outdoors, creating a consistent, untapped wind resource that can be converted into electricity. In a case study of a Colombian data center, the researchers used vertical axis Tesup V7 wind turbines to capture this man-made waste wind. The turbines, installed atop chillers, were chosen because they minimized size and weight while maximizing electricity generation.

The amount of gross electricity produced annually by six wind turbines was 513.82MWh from artificial airflow, exceeding the energy consumption of the facility’s fans, and providing a surplus of 131.2MWh. The authors suggest this recycled energy can be used for other electrical needs within the data center or be injected into the electrical grid.

The study, published in the journal Scientific Reports, also highlighted the economic and environmental benefits. A positive cash flow is achieved by the third year, with an impressive internal rate of return of 50.69%. Environmentally, the system reduces CO₂ emissions by approximately 300 metric tons annually.
