Thermal evaporation emerges as a promising strategy for scalable solid-state battery production

Solid-state lithium batteries are promising energy storage solutions that utilize solid electrolytes as opposed to the liquid or gel electrolytes found in traditional lithium-ion batteries (LiBs). Compared to LiBs and other batteries that are used worldwide, these batteries could attain significantly higher energy densities of more than 500 Wh/kg−1 and 1,000 Wh/l−1, which could be advantageous for powering electric vehicles and other electronics for longer periods of time.

Despite their possible advantages, existing solid-state lithium batteries exhibit significant limitations that have so far prevented their large-scale deployment. These include the active lithium loss that can occur while the batteries are charged and discharged, which can reduce their efficiency and overall performance.

This loss of lithium is caused by an inhomogeneous lithium plating. Devising effective strategies and thin lithium metal foils that could limit the loss of lithium in solid-state batteries is thus a key goal for the energy research community.

Amazon announces major milestone in EV transition with Rivian

Amazon announced a major milestone in its electric vehicle transition, officially bringing 20,000 Rivian EDVs (electric delivery vans) into its fleet.

Back in 2019, Amazon announced its Climate Pledge to achieve net-zero carbon emissions by 2040. Part of the Pledge included a partnership with Rivian for 100,000 all-electric delivery vehicles. The goal was to have all EDVs on the road and in the Amazon fleet by 2030.

The first Amazon-Rivian EDV hit the road in 2022, and since then, the vans have made it to thousands of locations across the United States.

Researchers address material challenges to make commercial fusion power a reality

Imagine if we could take the energy of the sun, put it in a container, and use it to provide green, sustainable power for the world. Creating commercial fusion power plants would essentially make this idea a reality. However, there are several scientific challenges to overcome before we can successfully harness fusion power in this way.

Researchers from the U. S. Department of Energy (DOE) Ames National Laboratory and Iowa State University are leading efforts to overcome material challenges that could make commercial fusion power a reality. The research teams are part of a DOE Advanced Research Projects Agency-Energy (ARPA-E) program called Creating Hardened And Durable fusion first Wall Incorporating Centralized Knowledge (CHADWICK). They will investigate materials for the first wall of a fusion reactor. The first wall is the structure that surrounds the fusion reaction, so it bears the brunt of the extreme environment in the fusion reactor core.

ARPA-E recently selected 13 projects under the CHADWICK program. Of those 13, Ames Lab leads one of the projects and is collaborating alongside Iowa State on another project, which is led by Pacific Northwest National Laboratory (PNNL).

Layer by layer: How simulations help manufacturing of modern displays

Modern materials must be recyclable and sustainable. Consumer electronics is no exception, with organic light-emitting diodes (OLEDs) taking over modern televisions and portable device displays. However, the development of suitable materials—from the synthesis of molecules to the production of display components—is very time-consuming.

Scientists led by Denis Andrienko of the Max Planck Institute for Polymer Research and Falk May from Display Solutions at Merck have now developed a simulation method that could significantly speed up the development of new materials.

High contrast and are key features of innovative . OLEDs use thin films of organic molecules, i.e. carbon-containing molecules, to achieve these goals.

How a Rare Mineral Is Illuminating Four Million Years of Solar History

The LOREX experiment utilizes lorandite ore to gauge historical solar neutrino flux, revealing insights about the Sun’s development and climatic effects through advanced decay rate measurements.

The Sun, Earth’s life-sustaining powerhouse, generates immense energy through nuclear fusion while emitting a steady stream of neutrinos — subatomic particles that reveal its inner workings. While modern neutrino detectors shed light on the Sun’s current behavior, key questions remain about its stability over millions of years — a timeframe encompassing human evolution and major climate changes.

Addressing these questions is the mission of the LORandite EXperiment (LOREX), which depends on accurately determining the solar neutrino cross-section for thallium. An international team of scientists has now achieved this crucial measurement using the unique Experimental Storage Ring (ESR) at GSI/FAIR in Darmstadt. Their groundbreaking results, advancing our understanding of the Sun’s long-term stability, have been published in the journal Physical Review Letters.

Vertical Farming: the Key to Sustainably Feeding 9 Billion People by 2050?

I believe that vertical farming will be able to meet the demand of 9.7 billion people by 2050 or even be able to feed eventually the entire globe or even space stations. The leading vertical farming company I like is aero farms:3.

By 2050, we’ll need to produce 70% more food to feed over 9 billion mouths. Luckily, a wide range of vertical farming companies are developing innovative solutions to redefine production, expand urban agriculture and transform consumers into green-fingered growers.

Glowing Plants and Silk-Coated Seeds: How MIT Is Developing the Future of Farming

Researchers at MIT are developing innovative agricultural technologies such as stress-signaling plants, microbial fertilizers, and protective seed coatings to adapt farming to climate change and enhance food security.

With global temperatures on the rise, agricultural practices must adapt to new challenges. Climate change is expected to increase the frequency of droughts, and some land may no longer be arable. Additionally, it is becoming increasingly difficult to feed an ever-growing population without expanding the production of fertilizer and other agrochemicals, which have a large carbon footprint that is contributing to global warming.

Now, scientists across MIT are tackling these issues from a variety of angles, including the development of plants that sound an alarm when they’re under stress and making seeds more resilient to drought. These technologies, and more yet to be devised, will be essential to feed the world’s population as the climate changes.

Innovative Device could Power Electronics using Body Movements

A new technology that can generate electricity from vibrations or even small body movements means you could charge your laptop by typing or power your smartphone’s battery on your morning run.

Researchers at the University of Waterloo have developed a tiny, wearable generator in response to the urgent need for sustainable, clean energy. It is also scalable for larger machines. Their paper, “Breaking Dielectric Dilemma: Polymer Functionalized Perovskite Piezocomposite with Large Current Density Output,” is published in the November edition of Nature Communications.

“This is a real game changer,” said Dr. Asif Khan, the project’s lead researcher and a postdoctoral fellow in the Department of Electrical and Computer Engineering at Waterloo. “We have made the first device of its kind that can power electronics at low cost and with unprecedented efficiency.”

Unlocking Primate Evolution: How a Complete Timetree Changes Everything

Recent scientific efforts have advanced the development of a comprehensive primate evolutionary timetree, filling significant gaps in our understanding of primate biodiversity and evolutionary history.

The primate order includes not only humanity’s closest relatives—the seven great apes—but also more than 450 species of monkeys, lemurs, lorises, and galagos. This group is remarkably diverse, ranging from 400-pound gorillas to tiny mouse lemurs (Microcebus) that weigh just one ounce. Primates display some of the most fascinating behaviors in the animal kingdom: chimpanzees use sticks to ‘fish’ for termites in hollow logs, while orangutans fashion leaf gloves to handle prickly durian fruit.

Despite being among the most thoroughly studied animals on Earth, primates still lack a complete molecular phylogenetic tree—a comprehensive evolutionary map detailing when different species emerged and how they are related. A robust phylogenetic tree would use genetic data to trace the timing of species’ appearances and identify their closest evolutionary relatives. Currently, the largest molecular timetree for primates includes just over 200 species. Even the most extensive synthetic timetree, based on more than 4,000 published studies, covers only about 400 species, leaving roughly one-fifth of the primate evolutionary tree unresolved.
