Article Abstract
We investigate the electronic properties of a graphene and α-ruthenium trichloride (α-RuCl) heterostructure using a combination of experimental techniques. α-RuCl is a Mott insulator and a Kitaev material. Its combination with graphene has gained increasing attention due to its potential applicability in novel optoelectronic devices. By using a combination of spatially resolved photoemission spectroscopy and low-energy electron microscopy, we are able to provide a direct visualization of the massive charge transfer from graphene to α-RuCl, which can modify the electronic properties of both materials, leading to novel electronic phenomena at their interface. A measurement of the spatially resolved work function allows for a direct estimate of the interface dipole between graphene and α-RuCl. Their strong coupling could lead to new ways of manipulating electronic properties of a two-dimensional heterojunction. Understanding the electronic properties of this structure is pivotal for designing next generation low-power optoelectronics devices.

Dielectric capacitors are vital for modern power and electronic systems, and accurate assessment of their dielectric properties is paramount. However, in many prevailing reports, the fringing effect near electrodes and parasitic capacitance in the test circuit were often neglected, leading to overrated dielectric performances. Here, the serious impacts of the fringing effect and parasitic capacitance are investigated both experimentally and theoretically on different dielectrics including AlO, SrTiO, etc.

Photoluminescence is one of the most intriguing properties of metal nanoclusters derived from their molecular-like electronic structure, however, achieving high photoluminescence quantum yield (PLQY) of metal core-dictated fluorescence remains a formidable challenge. Here, we report efficient suppression of the total structural vibrations and rotations, and management of the pathways and rates of the electron transfer dynamics to boost a near-unity absolute PLQY, by decorating progressive addition of cations. Specifically, with the sequential addition of Zn, Ag, and Tb into the 3-mercaptopropionic acids capped Au nanoclusters (NCs), the low-frequency vibration of the metal core progressively decreases from 144.

Hydroxyapatite nanoparticles (HANPs) are becoming increasingly crucial in dental implant applications as they are highly compatible with biological systems, actively support biological processes, and closely resemble bone minerals. This review covers the latest progress in how HANPs are made, studied, and used in dentistry. It looks at critical methods for creating HANPs, such as sol-gel, microwave hydrothermal synthesis, and biomimetic approaches, and how they affect the particles' size, structure, and activity.

Purpose: To develop a Chinese version of the 8-item Contact Lens Dry Eye Questionnaire (CLDEQ-8) with cross-cultural adaption and clinical validation among soft contact lens wearers (SCL) in China.
Methods: The translation and adaptation of the Chinese CLDEQ-8 (C-CLDEQ-8) followed a rigorous methodological process based on cross-cultural research guidelines consisting of three main phases: 1) forward and backward translation of original CLDEQ-8 into Chinese, 2) cross-cultural adaptation performed by medical advising committee, and 3) clinical validation and repeatability test of the translated questionnaire on Chinese SCL wearers. Rasch analysis was also performed to investigate the psychometric properties of C-CLDEQ-8.
