New global standard set for testing graphene’s single-atom thickness

Graphene could transform everything from electric cars to smartphones, but only if we can guarantee its quality. The University of Manchester has led the world’s largest study to set a new global benchmark for testing graphene’s single-atom thickness. Working with the UK’s National Physical Laboratory (NPL) and 15 leading research institutes worldwide, the team has developed a reliable method using transmission electron microscopy (TEM) that will underpin future industrial standards.

Researchers at the University of Manchester, working with the UK’s National Physical Laboratory and 15 international partners, have developed a robust protocol using transmission electron microscopy (TEM). The results, published in 2D Materials, will underpin a new ISO technical specification for graphene.

“To incorporate graphene and other 2D materials into industrial applications, from light-weight vehicles to sports equipment, touch screens, sensors and electronics, you need to know you’re working with the right material. This study sets a global benchmark that industry can trust,” said Dr. William Thornley, who worked on the research during his Ph.D.

Europa’s ocean may lack energy needed to support life

“If we could explore that ocean with a remote-control submarine, we predict we wouldn’t see any new fractures, active volcanoes or plumes of hot water on the seafloor,” said Dr. Paul Byrne.

Does Jupiter’s icy moon, Europa, contain the conditions for life as we know it? This is what a recent study published in Nature Communications hopes to address as a team of scientists from the United States and Canada investigated the likelihood of Europa’s subsurface ocean having the right conditions for life to exist. This study has the potential to help scientists better understand the necessary conditions for where life could exist, along with developing the methods for understanding them.

For the study, the researchers used a series of computer models to simulate potential tectonic activity on the seafloor of Europa’s subsurface ocean. The reason for studying tectonic activity on Europa is because this geological process is a key driver of life both existing and thriving on Earth. This is because plate tectonics are responsible for recycling nutrients to and from the Earth’s interior as it recycles materials like rocks and dust. This also enables the flow of water from the Earth’s interior to the seafloor. The researchers examined a myriad of mechanisms, including tidal forces, mantle convection, global contraction, and water-rock interactions (serpentinization).

In the end, the researchers found that Europa potentially does not exhibit these mechanisms to enable plate tectonics to be produced on Europa. They conclude that the liquid water making its way to the seafloor only occurs in the first few hundred feet, whereas plate tectonics occur over hundreds of miles. Finally, they conclude that is Europa does have life, they plate tectonics isn’t responsible for it.

From Nano to Nobel: National Lab Researchers Use MOFs to Solve Big Problems

Building on the foundational Nobel Prize-winning work, researchers at Berkeley Lab and its DOE user facilities continue to push MOF technology to address major global challenges.

For example, at the ALS, a team led by Yaghi traced how MOFs absorb water and engineered new versions to harvest water from the air more efficiently – an important step in designing MOFs that could help ease water shortages in the future. Yaghi is launching this technology through the company Waha, Inc, and working with scientists from the Energy Technologies Area to apply water-absorbing MOFs for in-building technologies and industrial applications.

Another team, led by joint Berkeley Lab and UC Berkeley scientist Jeffrey Long, used the ALS to study how flexible MOFs hold natural gas, with potential to boost the driving range of an adsorbed-natural-gas car – an alternative to today’s vehicles. An international team of scientists used the ALS to study the performance of a MOF that traps toxic sulfur dioxide gas at record concentrations; sulfur dioxide is typically emitted by industrial facilities, power plants, and trains and ships, and is harmful to human health and the environment. Others have used the facility to design luminous MOFs, or LMOFs, glowing crystals that can capture mercury and lead to clean contaminated drinking water.

Manganese gets its moment as a potential fuel cell catalyst

The road to a more sustainable planet may be partially paved with manganese. According to a new study by researchers at Yale and the University of Missouri, chemical catalysts containing manganese—an abundant, inexpensive metallic element—proved highly effective in converting carbon dioxide into formate, a compound viewed as a potential key contributor of hydrogen for the next generation of fuel cells.

The new study appears in the journal Chem. The lead authors are Yale postdoctoral researcher Justin Wedal and Missouri graduate research assistant Kyler Virtue; the senior authors are professors Nilay Hazari of Yale and Wesley Bernskoetter of Missouri.

Acid-treated carbon nanotubes boost efficiency and stability of flexible perovskite solar modules

Flexible perovskite solar modules (f-PSMs) are a key innovation in current renewable energy technology, offering a pathway toward sustainable and efficient energy solutions. However, ensuring long-term operational stability without compromising efficiency or increasing material costs remains a critical challenge.

In a study published in Joule, a joint research team from the Institute of Metal Research (IMR) of the Chinese Academy of Sciences and Zhengzhou University has achieved power conversion efficiency (PCE) surpassing 20% in flexible modules capable of withstanding a range of external stresses. The study highlights the use of single-walled carbon nanotubes (SWCNTs) as window electrodes for scalable f-PSMs.

SWCNT films exhibit excellent hydrophobicity, resisting moisture-induced degradation while enhancing device stability. Their flexibility and affordability further position SWCNT-based electrodes as a practical option for sustainable energy systems, providing an ideal opportunity for buildings and infrastructure to incorporate their own power sources in support of a net-zero carbon emissions future.

Water’s enigmatic surface: X-ray snapshots reveal atoms and molecules at work

Water is all around us, yet its surface layer—home to chemical reactions that shape life on Earth—is surprisingly hard to study. Experiments at SLAC’s X-ray laser are bringing it into focus.

Two-thirds of Earth’s surface is covered in water, most of it in oceans so deep and vast that only one-fifth of their total volume has been explored. Surprisingly, though, the most accessible part of this watery realm—the water’s surface, exposed on wave tops, raindrops and ponds full of skittering water striders—is one of the hardest to get to know.

Just a few layers of atoms thick, the surface plays an outsized role in the chemistry that makes our world what it is—from the formation of clouds and the recycling of water through rainfall to the ocean’s absorption of carbon dioxide from the atmosphere.

Artificial photosynthesis catalyst converts carbon dioxide into fuel using sunlight

A joint research team has developed a highly efficient photocatalyst that can convert carbon dioxide into the high-value-added fuel, methane, using sunlight, while explaining its operating principles. The work is published in the journal ACS Catalysis.

Carbon dioxide is a typical greenhouse gas, considered a major cause of climate change, and developing technologies to effectively reduce it is an important challenge worldwide.

The photocatalyst technology that caught the interest of the research team is a type of artificial photosynthesis technology that uses solar energy to convert carbon dioxide into fuel. It has garnered significant attention for its potential to contribute to carbon neutrality and eco-friendly energy production.

Two-step flash Joule heating method recovers lithium‑ion battery materials quickly and cleanly

A research team at Rice University led by James Tour has developed a two-step flash Joule heating-chlorination and oxidation (FJH-ClO) process that rapidly separates lithium and transition metals from spent lithium-ion batteries. The method provides an acid-free, energy-saving alternative to conventional recycling techniques, a breakthrough that aligns with the surging global demand for batteries used in electric vehicles and portable electronics.

Published in Advanced Materials, this research could transform the recovery of critical battery materials. Traditional recycling methods are often energy intensive, generate wastewater and frequently require harsh chemicals. In contrast, the FJH-ClO process achieves high yields and purity of lithium, cobalt and graphite while reducing energy consumption, chemical usage and costs.

“We designed the FJH-ClO process to challenge the notion that battery recycling must rely on acid leaching,” said Tour, the T.T. and W.F. Chao Professor of Chemistry and professor of materials science and nanoengineering. “FJH-ClO is a fast, precise way to extract valuable materials without damaging them or harming the environment.”

Commercially viable biomanufacturing: Designer yeast turns sugar into lucrative chemical 3-HP

Using a tiny, acid-tolerant yeast, scientists have demonstrated a cost-effective way to make disposable diapers, microplastics, and acrylic paint more sustainable through biomanufacturing.

A key ingredient in those everyday products is acrylic acid, an important industrial chemical that gives disposable diapers their absorbency, makes water-based paints and sealants more weather-proof, improves stain resistance in fabric, and enhances fertilizers and soil treatments.

Acrylic acid is converted from a precursor called 3-hydroxypropanoic acid, or 3-HP, which is made almost exclusively from petroleum through chemical synthesis—an energy-intensive process. But 3-HP can also be produced from renewable plant material by using engineered microbes to ferment plant sugars into this high-value chemical. Until now, however, the biomanufacturing process has not proven profitable.
