Imagine if your dead laptop or phone could charge in a minute or if an electric car could be fully powered in 10 minutes. While not possible yet, new research by a team of CU Boulder scientists could potentially lead to such advances.

Published today in the Proceedings of the National Academy of Sciences, researchers in Ankur Gupta’s lab discovered how ions, move within a complex network of minuscule pores. The breakthrough could lead to the development of more efficient energy storage devices, such as supercapacitors, said Gupta, an assistant professor of chemical and biological engineering.

“Given the critical role of energy in the future of the planet, I felt inspired to apply my chemical engineering knowledge to advancing energy storage devices,” Gupta said. “It felt like the topic was somewhat underexplored and, as such, the perfect opportunity.”

Collectively, the US’s 5 million solar installations can generate more than 179 gigawatts (GW) of electricity. Based on current trends, the SEIA claims that the US’s total solar capacity will soar to 673 GW by 2034, providing enough electricity to power 100 million homes.

The US will likely need to do better than that to meet the Biden Administration’s goal of 100% clean electricity by 2035, though. To decarbonize the grid by then, the Department of Energy (DoE) expects we’ll need as much as 1 terawatt (1,000 GWs) of solar capacity, enough for solar to meet 30–50% of the US’s electricity demand by itself.

A bioresorbable, wireless hydrogel (metagel) sensor, encompassing both biodegradable and stimulus-responsive hydrogels for ultrasonic monitoring of intracranial signals, was implanted into intracranial space with a puncture needle and deformed in response to physiological environmental changes.

Stored as heat in a bath of molten material, extra energy could be tapped when needed.

Researchers at Massachusetts Institute of Technology (MIT) discovered that adding a highly conductive substance called carbon black to a water and cement mixture created a construction material that could also serve as a supercapacitor.

Supercapacitors can charge and discharge extremely efficiently but are typically not capable of storing energy for long amounts of time. So while they lack the functionality of traditional lithium-ion batteries – which are found in everything from smartphones to electric cars – they are a useful method of storing excess electricity generated from renewable energy sources like solar and wind.

Since first unveiling the technology last year, the team has now built a working proof-of-concept concrete battery, the BBC reported. The MIT researchers are now hoping to build a 45-cubic-metre (1,590-cubic-feet) version capable of meeting the energy needs of a residential home.

In advancing sustainable waste management and CO₂ sequestration, researchers have crafted reactors that mineralize carbon dioxide with fly ash particles. This avant-garde technique is set to offer a sustainable and lasting solution to the pressing issue of greenhouse gas emissions, repurposing an industrial by-product in the process.

Newsweek ranked which states had the fewest health-related water safety violations based on data from the Environmental Protection Agency.

National University of Singapore (NUS) chemists have developed hexavalent photocatalytic covalent organic frameworks (COFs) which mimic natural photosynthesis for the production of hydrogen peroxide (H 2 O₂), an important industrial chemical.

The conventional method of H 2 O₂ production involves using anthraquinone as a catalyst to convert air and hydrogen into H 2 O₂. However, this process requires substantial energy, costly noble metal catalysts, high-pressure hydrogen gas and hazardous solvents. Artificial photosynthesis of H 2 O₂, resembling the natural photosynthesis process with the use of sunlight as an energy source and abundant water and air as feedstocks, presents a sustainable and promising alternative to the conventional anthraquinone process.

However, such an artificial system faces three key challenges: insufficient charge carrier generation and fast charge recombination, which lowers the efficiency; limited number of available catalytic sites, which results in low productivity; and lack of efficient delivery of charges and reactants to the catalytic sites, which causes sluggish reaction kinetics.

The billionaire’s bank balance won’t necessarily be $56 billion bigger if the vote really does go his way, since it’s non-binding. Expect the saga to continue.
