Harvesting more solar energy with two-dimensional supercrystals

Harvesting more solar energy with two-dimensional supercrystals

When Emiliano CortÃ©s goes hunting for sunlight‚ he doesn't use gigantic mirrors or sprawling solar farms. Quite the contrary‚ the professor of experimental physics and energy conversion at LMU dives into the nanocosmos.

Meteorites likely source of nitrogen for early Earth‚ Ryugu samples study finds

Meteorites likely source of nitrogen for early Earth‚ Ryugu samples study finds

Micrometeorites originating from icy celestial bodies in the outer solar system may be responsible for transporting nitrogen to the near-Earth region in the early days of our solar system. That discovery was published in Nature Astronomy by an international team of researchers‚ including University of Hawai'i at MÄnoa scientists‚ led by Kyoto University.

Study unveils shape-configurable MXene-based thermoacoustic loudspeakers with tunable sound directivity

Study unveils shape-configurable MXene-based thermoacoustic loudspeakers with tunable sound directivity

Recent research has led to the development of film-type shape-configurable speakers. These speakers‚ based on the unique properties of MXene‚ offer tunable sound directivity and hold immense promise for the rapidly growing field of wearable electronics. The study is published in Advanced Materials.

Researchers decode aqueous amino acid's potential for direct air capture of COâ‚‚

Scientists at the Department of Energy's Oak Ridge National Laboratory have made a significant stride toward understanding a viable process for direct air capture‚ or DAC‚ of carbon dioxide from the atmosphere. This DAC process is in early development with the aim of achieving negative emissions‚ where the amount of carbon dioxide removed from the envelope of gases surrounding Earth exceeds the amount emitted.

Do we live in a giant void? That could solve the puzzle of the universe's expansion‚ research suggests

Do we live in a giant void? That could solve the puzzle of the universe's expansion‚ research suggests

One of the biggest mysteries in cosmology is the rate at which the universe is expanding. This can be predicted using the standard model of cosmology‚ also known as Lambda-cold dark matter (Î›CDM). This model is based on detailed observations of the light left over from the Big Bang—the so-called cosmic microwave background (CMB).

'End of century' extreme heat and drought conditions in Europe could occur much earlier than previously thought

'End of century' extreme heat and drought conditions in Europe could occur much earlier than previously thought

Simultaneous episodes of extreme heat and drought—typical of a moderate warming scenario predicted for the end of the 21st century—could occur earlier and repeatedly in Europe‚ reports a study published in Communications Earth &; Environment.

Control over friction‚ from small to large scales

Control over friction‚ from small to large scales

Friction is hard to predict and control‚ especially since surfaces that come in contact are rarely perfectly flat. New experiments demonstrate that the amount of friction between two silicon surfaces‚ even at large scales‚ is determined by the forming and rupturing of microscopic chemical bonds between them. This makes it possible to control the amount of friction using surface chemistry techniques. This research has been published in Physical Review Letters.

Plant points: Researchers say looking beyond the mean is key to understanding plant patterns

Plant points: Researchers say looking beyond the mean is key to understanding plant patterns

When it comes to studying patterns in how bugs damage plants‚ is it important to know the average amount and type of damage? Or the variation around the average?

Two methods for demonstrating how photolyase isolates use light to repair damaged DNA

Two methods for demonstrating how photolyase isolates use light to repair damaged DNA

Two teams of bio-researchers have developed similar processes for demonstrating how photolyase isolates use light to repair damaged DNA. In their papers‚ both published in the journal Science‚ the two groups outline their stop-motion-animation-type process to capture the action in detail.
