A new carbon allotrope with high carrier mobility and optical absorption.

Carbon atom has different bonding modes, which provides the possibility for the existence of multilayer carbon allotropes. Among these bonding modes, the sp hybrid bonding mode often causes atoms to be noncoplanar. This provides the possibility for the emergence of two-dimensional (2D) multilayer materials.

Article Synopsis
- Perovskite light-emitting diodes (PeLEDs) are gaining attention for their potential in advanced displays, with vacuum deposition being a promising manufacturing method due to its efficiency and ease of pixelation.
- A new trisource coevaporation strategy has been introduced to create a specific perovskite structure (MACsPbBr) that enhances carrier confinement and reduces defects, resulting in a significant increase in external quantum efficiency (EQE).
- The study reports the development of the first vacuum-deposited transparent PeLEDs, which feature double-sided emission and a high EQE of 7.6%, and demonstrates their use in a multifunctional intelligent display capable of heart rate detection and imaging.
Hummingbirds rapidly respond to the removal of visible light and control a sequence of rate-commanded escape manoeuvres in milliseconds.

Hummingbirds routinely execute a variety of stunning aerobatic feats, which continue to challenge current notions of aerial agility and controlled stability in biological systems. Indeed, the control of these amazing manoeuvres is not well understood. Here, we examined how hummingbirds control a sequence of manoeuvres within milliseconds, and tested whether and when they use vision during this rapid process.

Aβ42 aggregation was implicated in the pathogenesis of Alzheimer's disease (AD) without effective treatment available currently. Future efforts in clinical trials should instead focus on applying those antiamyloid treatment strategies to the preclinical stage and "the earlier, the better". How to identify and inhibit Aβ42 oligomers in the different stages of aggregation is therefore becoming the key to controlling primary aggregation and consequent AD development.

Purpose: Myopia is a refractive error that impairs visual function and leads to visual blurring. This study aims to investigate the effect of violet light (VL) on controlling myopia, specifically in terms of axial length (AL), spherical equivalent refraction (SER), and visual acuity (VA).
Methods: A systematic review was conducted to compare VL and single-vision spectacles (SVSs) for treating childhood myopia.
