Revolutionizing surface science: Visualization of local dielectric properties of surfaces

2025-03-07
(Press-News.org) Researchers from the University of Electro-Communications (Akira Sumiyoshi and Jun Nakamura) and Tohoku University (Kohei Yamasue and Yasuo Cho) have made a significant advancement in visualizing the local dipole moments at the semiconductor surface. This study offers unprecedented insights into the atomic-scale charge distribution and dipole configuration using a combination of the scanning nonlinear dielectric microscope (SNDM) and advanced density functional theory (DFT) calculations.

The newly developed simulation method focuses on the Si(111) surfaces, revealing that a local upward dipole moment is prominently observed at the adatom sites. This observation aligns closely with experimental results obtained through SNDM, demonstrating the accuracy and effectiveness of the theoretical approach.

The findings reveal that variations in local atomic arrangements significantly influence charge transfer and, consequently, the dipole moments, providing essential information for interpreting surface probe microscopy images. This study not only enhances the understanding of surface dielectric properties but also holds promising implications for future semiconductor device engineering and material science applications.

The results were published as an open-access article in "Scientific Reports" by Springer Nature on March 3rd, 2025.

Nearly half of popular tropical plant group related to birds-of-paradise and bananas are threatened with extinction

Nearly half of popular tropical plant group related to birds-of-paradise and bananas are threatened with extinction
2025-03-07
A new analysis from researchers at the Smithsonian’s National Museum of Natural History reveals that nearly half of the genus Heliconia, a group of tropical plants popular for their bright, beak-shaped flowers, are threatened with extinction. The findings, published today, March 7, in the journal Plants, People, Planet, reveal that many of these imperiled plants are not found within protected areas or botanical gardens, making additional conservation action crucial to saving these charismatic, horticulturally important and ecologically significant floras. The new work places Heliconia among a select group of plants to undergo a detailed, comprehensive ...

The changing chorus: How movements and memories influence birdsong evolution
2025-03-07
New research from the University of Oxford has provided fresh insights into how bird songs evolve over time, revealing a significant role for population dynamics in shaping song diversity and change. The findings – based on an analysis of over 100,000 bird songs – have been published today (7 March) in the journal Current Biology.  The researchers spent three years collecting over twenty thousand hours of sound recordings from a wild population of great tits (Parus major) in Oxfordshire, which has been studied for the past 77 years as part of the Wytham Great Tit study. ...

One in 15 U.S. adults have been on the scene of a mass shooting

2025-03-07
About 7% of U.S. adults have been present at the scene of a mass shooting in their lifetime, and more than 2% have been injured during one, according to new University of Colorado Boulder research. The study, published March 7 in the journal JAMA Network Open, also found that younger generations were significantly more likely to have been exposed than their parents or grandparents were. Generation Z— adults born after 1996—were at greatest risk. “This study confirms that mass shootings are not isolated tragedies, but ...

Prevalence of depression and anxiety among adults with chronic pain

2025-03-07
About The Study: In this systematic review and meta-analysis of depression and anxiety among individuals with chronic pain, approximately 40% of adults had clinically significant depression and anxiety. Women, younger people, and people with nociplastic pain were most likely to have depression and anxiety. The co-occurrence of chronic pain with depression and anxiety is a significant public health concern necessitating routine screening in clinical settings, equitable access to specialty care, and innovative treatment development.

Direct exposure to mass shootings among US adults

2025-03-07
About The Study: The findings from this survey study of U.S. adults underscore the extensive and often overlooked regular exposure to mass shootings in this country. The demographic disparities in exposure highlight the need for targeted interventions and support for the most affected groups, particularly younger generations and males. Understanding these patterns is essential for addressing the broader impacts of gun violence on public health and community well-being.

ITSN1 gene linked to substantial risk of Parkinson’s disease

2025-03-07
HOUSTON – (March 7, 2025) – A new study published in Cell Reports reveals a breakthrough discovery linking genetic variants in the gene ITSN1 to a significantly elevated risk of Parkinson’s disease, a neurodegenerative condition that affects nearly 2% of adults older than 65 years. This work, led by an international team of researchers at Baylor College of Medicine, AstraZeneca and the Jan and Dan Duncan Neurological Research Institute at Texas Children’s Hospital, could pave the way for new treatments aimed at slowing or preventing Parkinson’s disease progression. “Parkinson’s disease, the ...

KTU scientists develop advanced forest monitoring systems: Will forests monitor themselves in the future?

KTU scientists develop advanced forest monitoring systems: Will forests monitor themselves in the future?
2025-03-07
“Forests are among the most important ecosystems in nature, constantly evolving, yet their monitoring is often delayed,” says Rytis Maskeliūnas, a professor at Kaunas University of Technology (KTU). Climate change, pests, and human activity are transforming forests faster than we can track them – some changes become apparent only when the damage is already irreversible. KTU researchers are proposing innovative technological solutions: an innovative forest regeneration model and a sound analysis system that can predict forest conditions and detect environmental changes in real time. Forest ...
