High-dose gold nanoparticle treatment outperformed orlistat in reversing obesity-related damage in rats, according to research conducted by Alexandria University, Erbil Polytechnic University, and Pharos University.

Attosecond time-resolved experiments have revealed the increasing importance of electronic correlations in the collective plasmon response as the size of the system decreases to sub-nm scales.

A collaborative study published on January 21 in Nature Communications presents a novel strategy to improve the effectiveness of radiotherapy for nasopharyngeal carcinoma (NPC).

Nanoparticle researchers spend most of their time on one thing: counting and measuring nanoparticles. Each step of the way, they have to check their results. They usually do this by analyzing microscopic images of hundreds of nanoparticles packed tightly together. Counting and measuring them takes a long time, but this work is essential for completing the statistical analyses required for conducting the next, suitably optimized nanoparticle synthesis.

The skin serves as the body's primary defense against harmful microorganisms, toxins, and physical damage. However, severe injuries from burns, trauma, surgery, or conditions like diabetes can compromise its ability to heal naturally, necessitating advanced wound care solutions. While minor wounds can heal with conventional care, severe injuries demand innovative materials and techniques to ensure rapid and complication-free healing.

Researchers from Murdoch University and The University of Western Australia found the forewings of the fruit-sucking moth (Eudocima aurantia) have the appearance of a crumpled leaf—but are in fact flat.

Particle detectors play a crucial role in our understanding of the fundamental building blocks of the universe. They allow scientists to study the behavior and properties of the particles produced in high-energy collisions. Such particles are boosted to near the speed of light in large accelerators and then smashed into targets or other particles where they are then analyzed with detectors. Traditional detectors, however, lack the needed sensitivity and precision for certain types of research.

A new study led by Rice University materials scientist Lane Martin sheds light on how the extreme miniaturization of thin films affects the behavior of relaxor ferroelectrics—materials with noteworthy energy-conversion properties used in sensors, actuators and nanoelectronics. The findings reveal that as the film shrinks to dimensions comparable to the materials' internal polarization structures, their fundamental properties can shift in unexpected ways.

A research team from the Eye & ENT Hospital of Fudan University, China, has developed a novel biocompatible nanoadhesive for corneal transplantation. The nanoadhesive is based on tetrahedral framework nucleic acids combined with functionalized polycationic recombinant proteins. This unique composition minimizes the risks of tissue necrosis and inflammation associated with polymeric adhesives while inhibiting bacterial growth and promoting tissue repair. This work demonstrates an efficient strategy to break through the bottleneck of current ophthalmic adhesives.

Researchers from Tokyo Metropolitan University have elucidated how hydrogen and carbon monoxide is adsorbed into solids containing a crown-motif structure of platinum and gold. Using quick-scan X-ray absorption measurements and theoretical calculations, they studied a solid of [PtAu8(PPh3)8]-H[PMo12O40] called PtAu8-PMo12 and found that gas adsorption is affected strongly by the dimension of nanoscale voids in the structure.

University of Waterloo researchers have pinpointed for the first time how microplastics accumulate in coral reefs, a key step to understanding how to protect vulnerable ecosystems.

Researchers have developed a sustainable catalyst that increases its activity during use while converting carbon dioxide (CO2) into valuable products. This discovery offers a blueprint for designing next-generation electrocatalysts.

Harvard University and the Chinese University of Hong Kong researchers have developed a technique that increases the solubility of drug molecules by up to three orders of magnitude. This could be a breakthrough in drug formulation and delivery.
