Observing quantum coherent oscillations in a three-level atom via electromagnetically induced transparency by two-dimensional spectroscopy.

Two-dimensional electronic spectroscopy (2DES) has high spectral resolution and is a useful tool for studying atomic dynamics. In this paper, we show a smallest unit of electromagnetically induced transparency (EIT) for 2DES, i.e.

Aquatic high iron induces hepatic ferroptosis in zebrafish (Danio rerio) via interleukin-22 signaling pathway.

Iron is one of the indispensable trace elements in living organisms. However, excessive iron deposition in organisms is prone to induce dysfunction of the liver and other vital organs. The present study aimed to investigate the mechanism how aquatic high iron affects iron transport and induces hepatic injury in zebrafish.

Magnetic Field-Driven NiCo-3DOMC Modified Separators for Effective Lithium Polysulfide Mitigation and Catalysis.

Lithium-sulfur batteries (LSBs) face challenges from the shuttle effect of lithium polysulfides (LiPSs) and slow redox kinetics. In this study, a NiCo-Doped 3D Ordered Mesoporous Carbon (NiCo-3DOMC) composite material is synthesized using a gel-crystalline template and sol-gel method to modify polypropylene separators in LSBs. Density Functional Theory calculations and experiment results demonstrate that under a magnetic field, the NiCo-3DOMC enhances adsorption and catalyzes the conversion of LiPSs, effectively mitigating the shuttle effect and boosting redox kinetics.

High-performance 2D electronic devices enabled by strong and tough two-dimensional polymer with ultra-low dielectric constant.

As the feature size of microelectronic circuits is scaling down to nanometer order, the increasing interconnect crosstalk, resistance-capacitance (RC) delay and power consumption can limit the chip performance and reliability. To address these challenges, new low-k dielectric (k < 2) materials need to be developed to replace current silicon dioxide (k = 3.9) or SiCOH, etc.

Transcriptome analysis reveals the genetic basis underlying the formation and seasonal changes of nuptial pads in Rana chensinensis.

Background: Nuptial pads, a typical sexually dimorphic trait in anurans, are located on the first digit of the male forelimb in Rana chensinensis and exhibit morphological changes synchronized with breeding cycles. However, the genetic mechanisms underlying its formation and seasonal changes remain poorly understood.

Results: To identify genes and biological processes associated with the development and seasonal variations of nuptial pads, we conducted a comprehensive transcriptome analysis on nuptial pads and hind toe skin across both sexes at different breeding periods in R.
