1 Introduction The rapid development of MOCVD, which is known as a highly reproducible technique to fabricate 2D TMDC materials on multi-wafer scale, has triggered huge interest in both scientific and industrial communities. Despite the enormous number of reports on advanced MOCVD recipe design[1-5] and superior 2D device performance,[6-10] it is still challenging and time-consuming to develop and optimize MOCVD recipes from nucleation to wafer-scale fully-coalesced monolayers (MLs).

Abstract : Objective: To investigate the factors affecting the duration of continuous breastfeeding of infants within 2 years of age, and to explore intervention strategies that may promote breastfeeding duration in China. Method: A self-made electronic questionnaire was used to investigate the breastfeeding duration of infants, and the influencing factors were collected from three levels of individual, family, and social support.
