Ecosystem Under Siege: An Alien Invasion That Could Trigger Catastrophic Changes Is Underway Across North America

Posted by in categories: evolution, sustainability

An alien invasion capable of triggering catastrophic changes is underway across North America. At least 70 imported earthworm species have colonized the continent, and represent a largely overlooked threat to native ecosystems, according to a new study by researchers at Stanford University, Sorbonne University, and other institutions.

The analysis, recently published in the journal Nature Ecology & Evolution, provides the largest-ever database of such earthworms and warns of the need to better understand and manage the invaders in our midst.

“Earthworms tell the story of the Anthropocene, the age we live in,” said study senior author Elizabeth Hadly, the Paul S. and Billie Achilles Professor in Environmental Biology in the Stanford School of Humanities and Sciences. “It is a story of global homogenization of biodiversity by humans, which often leads to the decline of unique local species and the disruption of native ecosystem processes.”

Harnessing light with hemispherical shells for improved photovoltaics

Posted by in categories: computing, solar power, sustainability

In the pursuit of sustainable energy solutions, the quest for more efficient solar cells is paramount. Organic photovoltaic cells have emerged as a promising alternative to traditional silicon-based counterparts due to their flexibility and cost-effectiveness. However, optimizing their performance remains a significant challenge.

In a pioneering move, new research from Abdullah Gül University (Türkiye) reimagines the structure of organic photovoltaic cells, opting for a hemispherical shell shape to unlock unprecedented potential in and angular coverage.

As reported in the Journal of Photonics for Energy, this innovative configuration aims to maximize light absorption and angular coverage, promising to redefine the landscape of renewable energy technologies. The study presents advanced computational analysis and comparative benchmarks to spotlight the remarkable capabilities of this new design.

The Tesla Designer Who Translates Elon Musk’s Musings Into Reality

Posted by in categories: Elon Musk, sustainability, transportation

Tesla Chief Executive Elon Musk told his top designer he wanted to make an electric pickup that would have good driving dynamics and a covered bed—and “feel like the future.”

It was up to Franz von Holzhausen to decipher what his boss meant.

Tesla is now accounting for ‘battery age’ in its range calculation

Posted by in categories: sustainability, transportation

Tesla is now starting to account for “battery age” in its estimated range calculation for its electric vehicles.

I have long been advocating for prioritizing accurate range prediction over a longer range in curbing range anxiety.

Don’t get me wrong, a longer range can be useful, but if you know what where you are going, the main thing is that you know you can get there and your range doesn’t start dropping faster than anticipated.

Unleashing the Power: BatMan Project Revolutionizes Battery Manufacturing

Posted by in categories: computing, sustainability, transportation

Gotham City’s Dark Knight boasts an impressive collection of technological marvels, but the superhero scientists at the U.S. Department of Energy’s (DOE’s) National Renewable Energy Laboratory (NREL) have cutting-edge capabilities of their own.

A recent battery manufacturing project—affectionately called BatMan —has developed a novel laser patterning process to alter the microstructure of battery electrode materials. Funded by DOE’s Advanced Materials and Manufacturing Technologies Office, this project brings together expert minds from NREL, Clarios, Amplitude Laser Group, and Liminal Insights. This revolutionized manufacturing process could unlock significant improvements to electrified transportation, leading the charge toward a brighter and more sustainable future.

“BatMan builds on NREL’s expertise using laser ablation, advanced computational models, and materials characterization to address key challenges in battery manufacturing,” said Bertrand Tremolet de Villers, project co-lead and senior scientist in NREL’s Thin Film and Manufacturing Sciences group. “This new, high-throughput laser patterning process—demonstrated at scale with state-of-the-art roll-to-roll manufacturing techniques—uses laser pulses to quickly and precisely modify and optimize electrode structures, offering a massive leap in battery capabilities with minimal added manufacturing cost.”

Battery Breakthrough Could Allow Electric Cars To Go 1,000 km on Single Charge

Posted by in categories: nanotechnology, particle physics, robotics/AI, sustainability, transportation

Futuristic advancements in AI and healthcare stole the limelight at the tech extravaganza Consumer Electronics Show (CES) 2024. However, battery technology is the game-changer at the heart of these innovations, enabling greater power efficiency. Importantly, electric vehicles are where this technology is being applied most intensely. Today’s EVs can travel around 700km on a single charge, while researchers are aiming for a 1,000km battery range. Researchers are fervently exploring the use of silicon, known for its high storage capacity, as the anode material in lithium-ion batteries for EVs. However, despite its potential, bringing silicon into practical use remains a puzzle that researchers are still working hard to piece together.

Enter Professor Soojin Park, PhD candidate Minjun Je, and Dr. Hye Bin Son from the Department of Chemistry at Pohang University of Science and Technology (POSTECH). They have cracked the code, developing a pocket-friendly and rock-solid next-generation high-energy-density Li-ion battery system using micro silicon particles and gel polymer electrolytes. This work was published on the online pages of Advanced Science on the 17th of January.

Employing silicon as a battery material presents challenges: It expands by more than three times during charging and then contracts back to its original size while discharging, significantly impacting battery efficiency. Utilizing nano-sized silicon (10-9m) partially addresses the issue, but the sophisticated production process is complex and astronomically expensive, making it a challenging budget proposition. By contrast, micro-sized silicon (10-6m) is superbly practical in terms of cost and energy density. Yet, the expansion issue of the larger silicon particles becomes more pronounced during battery operation, posing limitations for its use as an anode material.
