Abstract This study aimed to evaluate tissue thickness and vascularization of graft donor sites in heavy/chronic smokers and non-smokers using high-frequency ultrasonography. This single-center case–control study included 42 systemically healthy individuals (21 smokers, 21 heavy/chronic smokers) requiring palatal graft harvesting. Smoking status was biochemically confirmed using salivary cotinine. Preoperative high-frequency ultrasonography evaluated tissue thickness, density, and vascularization.

The possibility that current passing through an organic molecule becomes spin-polarized is highly intriguing. Amongst these molecules, helicene units have recently been shown to exhibit such a chiral-induced spin selectivity (CISS) effect. Thus, helical nanographenes (NGs), whose core building block is a helicene unit, are natural candidates for generating CISS.

1 Introduction The rapid advancement of optoelectronic devices has profoundly shaped 21st-century technology.[1] At the forefront of this revolution are phototransistors, which integrate light detection and signal amplification to power next-generation applications such as digital imaging, optical communication, and logic gates.[2] High-performance phototransistors demand materials with high charge carrier mobility and robust photoresponsive characteristics, characterized by a high absorption...
