Versatile recognition of graphene layers from optical images under controlled illumination through green channel correlation method.

In this study, a simple yet versatile method is proposed for identifying the number of exfoliated graphene layers transferred on an oxide substrate from optical images, utilizing a limited number of input images for training, paired with a more traditional number of a few thousand well-published Github images for testing and predicting. Two thresholding approaches, namely the standard deviation-based approach and the linear regression-based approach, were employed in this study. The method specifically leverages the red, green, and blue color channels of image pixels and creates a correlation between the green channel of the background and the green channel of the various layers of graphene.

CVD Synthesis of MoS Using a Direct MoO Precursor: A Study on the Effects of Growth Temperature on Precursor Diffusion and Morphology Evolutions.

In this study, the influence of growth temperature variation on the synthesis of MoS using a direct MoO precursor was investigated. The research showed that the growth temperature had a strong impact on the resulting morphologies. Below 650 °C, no nucleation or growth of MoS occurred.

Signatures of hot carriers and hot phonons in the re-entrant metallic and semiconducting states of Moiré-gapped graphene.

Stacking of graphene with hexagonal boron nitride (h-BN) can dramatically modify its bands from their usual linear form, opening a series of narrow minigaps that are separated by wider minibands. While the resulting spectrum offers strong potential for use in functional (opto)electronic devices, a proper understanding of the dynamics of hot carriers in these bands is a prerequisite for such applications. In this work, we therefore apply a strategy of rapid electrical pulsing to drive carriers in graphene/h-BN heterostructures deep into the dissipative limit of strong electron-phonon coupling.

Management of bronchomalacia in infants post-cardiac surgery using synchronized nasal DuoPAP: A novel technology.

Background: Tracheo-bronchomalacia (TBM) is the weakness in the structural integrity of the cartilaginous ring and arch. It may occur in isolation with prematurity or secondarily in association with various congenital anomalies. Bronchomalacia is more commonly associated with congenital heart diseases.

CVD Synthesis of Intermediate State-Free, Large-Area and Continuous MoS via Single-Step Vapor-Phase Sulfurization of MoO Precursor.

The low evaporation temperature and carcinogen classification of commonly used molybdenum trioxide (MoO) precursor render it unsuitable for the safe and practical synthesis of molybdenum disulfide (MoS). Furthermore, as evidenced by several experimental findings, the associated reaction constitutes a multistep process prone to the formation of uncontrolled amounts of intermediate MoSO phase mixed with the MoS crystals. Here, molybdenum dioxide (MoO), a chemically more stable and safer oxide than MoO, was utilized to successfully grow cm-scale continuous films of monolayer MoS.
