Understanding photogenerated carrier transport in 2D perovskites, especially surface states, is challenging with conventional time-resolved techniques. Scientists at KAUST utilized scanning ultrafast electron microscopy (SUEM) with groundbreaking surface sensitivity to disclose carrier diffusion rates of ~30 cm²/s for n=1, 180 cm²/s for n=2, and 470 cm²/s for n=3, which are notably higher than bulk. This highlights the SUEM’s potential for advancing the understanding of carrier dynamics. Density Functional Theory (DFT) confirms broader carrier transmission channels at the surface, offering key insights for optimizing 2D perovskite optoelectronic devices.

In a paper published in National Science Review, a research team from the Chinese Academy of Sciences investigated impact melt rocks from the Chang'e-6 lunar soils and determined that the Moon's South Pole-Aitken basin formed 4.25 billion years ago. China’s Chang'e-6 mission, launched on May 3, 2024, landed on June 2, and returned on June 25, collecting 1935.3 grams of lunar soil samples – the first ever returned from the Moon's far side.

Inspired by the concept of harmonious coexistence between humans and nature, a new concept, biogenic construction for civil engineering is proposed in this paper, as well as the definition, framework and four components.

Researchers at Saratov State University and their colleagues have developed an innovative approach to improving the visualization of subsurface blood vessels using laser speckle contrast imaging (LSCI) enhanced with principal component analysis (PCA).

This study explores the effects of Alpiniae oxyphyllae Fructus (AOF) on renal lipid deposition in diabetic kidney disease and elucidate its molecular mechanisms.

Research team proposed a UAV system for SAR missions based on consortium blockchain with sharding. It improves adaptability by dynamically creating shards and enhances interoperability via Merkle proof-based cross-shard interaction.
