New research has uncovered a possible clue as to why glaciers that terminate at the sea are retreating at unprecedented rates: the bursting of tiny, pressurized bubbles in underwater ice.

Scientists have devised an efficient method of recovering high-purity silicon from expired solar panels to produce lithium-ion batteries that could help meet the increasing global demand to power electric vehicles.

Antarctica's vast ice masses seem far away, yet they store enough water to raise global sea levels by several meters. A team of experts has now provided the first systematic stability inspection of the ice sheet's current state. Their diagnosis: While they found no indication of irreversible, self-reinforcing retreat of the ice sheet in West Antarctica yet, global warming to date could already be enough to trigger the slow but certain loss of ice over the next hundreds to thousands of years.

As drinking water flows through pipes and into a glass, it runs against the rubber seals inside some plumbing devices. These parts contain additives that contribute to their flexibility and durability, but these potentially harmful compounds can leak into drinking water, according to a small-scale study. The authors report that the released compounds, which are typically linked to tire pollution, also transformed into other unwanted byproducts.

When we determine which communities are more likely to get their water from contaminated supplies, median household income is not the best measure. That's according to a recent study that found social factors -- such as low population density, high housing vacancy, disability and race -- can have a stronger influence than median household income on whether a community's municipal water supply is more likely to have health-based water-quality violations.

Right at the bottom of the deep sea, the first very simple forms of life on earth probably emerged a long time ago. Today, the deep sea is known for its bizarre fauna. Intensive research is being conducted into how the number of species living on the sea floor have changed in the meantime. Some theories say that the ecosystems of the deep sea have emerged again and again after multiple mass extinctions and oceanic upheavals. Today's life in the deep sea would thus be comparatively young in the history of the Earth. But there is increasing evidence that parts of this world are much older than previously thought.

Lithium-ion batteries (LIBs) provide our portable devices like tablets and mobiles -- and increasingly also vehicles -- with power. As the share of volatile renewable energy needing electricity storage increases, more and more LIBs are needed, lithium prices rise, resources dwindle, and the amount of depleted batteries that contain toxic substances increases. Researchers introduce a novel approach for the recovery of lithium from used LIBs.

Simultaneous wireless information and power transfer (SWIPT)-aided nonorthogonal multiple access (NOMA) system, used for communication in the Industrial Internet of Things (IIoTs), suffers from significant energy loss with transmission distance. Now, researchers have developed an energy-efficient framework by applying SWIPT-NOMA to a distributed antenna system. This technology is expected to pave the way for more efficient and optimized IoT environments.

Engineers aim to revolutionize rechargeable batteries: Their thin-film batteries are not only safer and longer-lasting than conventional lithium-ion batteries, they are also much more environmentally friendly to manufacture and can be charged in just one minute. For now, the battery is very small, but the founders have big plans for it.

Scientists have developed a flexible battery as thin as a human cornea, which stores electricity when it is immersed in saline solution, and which could one day power smart contact lenses.

A new study has found a way to prevent lithium plating in electric vehicle batteries, which could lead to faster charging times.

Carbon slurries, which consist of a suspension of carbon particles in a solvent, are used to mass-produce battery electrodes. However, there are no adequate methods to evaluate whether the particles are uniformly dispersed in the slurry during the manufacturing process. In a recent study, researchers used an innovative approach, combining viscosity and electrochemical impedance measurements, to accurately assess the dispersibility of slurries, opening doors to enhanced electric vehicles and fuel cell batteries.

Efficient and cheap batteries that can also capture harmful emissions could be right around the corner, thanks to a new system that speeds up the development of catalysts for lithium-CO2 (Li-CO2) batteries.

Zinc-air batteries have emerged as a better alternative to lithium in a recent study into the advancement of sustainable battery systems.

Sodium, Potassium and zinc have all been promising contenders for lithium's place in rechargeable batteries of the future, but researchers have added an unusual and more abundant competitor to the mix: chloride, the richest negatively charged ions in seawater. Xiaowei Teng, the James H. Manning professor of Chemical Engineering at WPI, has discovered a new redox chemistry empowered by chloride ions for the development of seawater green batteries.

An international research team reported the first realization of single-crystalline T-Nb2O5 thin films having two-dimensional (2D) vertical ionic transport channels, which results in a fast and colossal insulator-metal transition via Li ion intercalation through the 2D channels.

Rather than being solely detrimental, cracks in the positive electrode of lithium-ion batteries reduce battery charge time, research shows. This runs counter to the view of many electric vehicle manufacturers, who try to minimize cracking because it decreases battery longevity.

Engineers have created a 'supercapacitor' made of ancient, abundant materials, that can store large amounts of energy. Made of just cement, water, and carbon black (which resembles powdered charcoal), the device could form the basis for inexpensive systems that store intermittently renewable energy, such as solar or wind energy.
