Covalent organic frameworks show great potential for efficient energy transport
Laura Spieth examines one of the COF thin films investigated in the study. Credit: Florian Wolf An interdisciplinary research team from LMU, Technical University of Munich (TUM) and the University of Oxford has used a new spectroscopic technique to investigate the diffusion of excited states in covalent organic frameworks (COFs). These modular materials can be tailored to desired properties through…

Decoding 2D materials growth: Insights in white graphene open door to cleaner energy and more efficient electronics
a) The diffusion route of borazine on Ru(0001) shows that borazine moves by alternating rotational movements between HCP and FCC sites as it diffuses across the surface. Regarding hydrogen removal from borazine, b) shows that B-dehydrogenation is the kinetically favored product, while N-dehydrogenation is thermodynamically favored. Credit: Small (2025). DOI: 10.1002/smll.202405404 A breakthrough in deciphering the growth process of the…

Dark energy camera captures sparkling galaxies in the Antria star cluster
The Antria Galaxy Cluster (Abell S636) is a group of at least 230 galaxies located approximately 130 million light-years away in the direction of the Antria constellation (air pump). There are many different types of galaxies, including lenticular galaxies, irregular galaxies, and microdwarfs. This cluster is dominated by two giant elliptical galaxies: NGC 3268 (center) and NGC 3258 (bottom right).…

Leaf resilience to raindrops provides insight into energy harvesting potential
Credit: Pixabay/CC0 Public Domain To a leaf, a falling raindrop has the same mass as a bowling ball falling on a person. So how do leaves survive? A new study sheds light on the physical dynamics that help leaves react to the effects of raindrops, with potential applications in agriculture and renewable energy harvesting. In the paper “Resonance and damping…

Carbon offsets can bring energy efficiency to low-income Americans — Nashville data is promising
Credit: Pixabay/CC0 Public Domain Under pressure from customers and investors, many U.S. companies have pledged to voluntarily reduce their climate impact. But that doesn’t necessarily mean they’re reducing their own greenhouse gas emissions. Many companies instead pay other companies to reduce carbon emissions on their behalf through projects that generate carbon offsets. There are reasons to be skeptical of this…
