Graphene-hexagonal boron nitride (hBN) scalable heterostructures are pivotal for the development of graphene-based high-tech applications. In this work, we demonstrate the realization of high-quality graphene-hBN heterostructures entirely obtained with scalable approaches. hBN continuous films were grown via ion beam-assisted physical vapor deposition directly on commercially available SiO/Si and used as receiving substrates for graphene single-crystal matrixes grown by chemical vapor deposition on copper.

Five preregistered studies ( = 1934) demonstrate that the prevalent U.S. ideology to "follow your passions" perpetuates academic and occupational gender disparities compared to some other cultural ideologies.

The interest in the research of the structural and electronic properties between graphene and lithium has bloomed since it has been proven that the use of graphene as an anode material in lithium-ion batteries ameliorates their performance and stability. Here, we investigate an alternative route to intercalate lithium underneath epitaxially grown graphene on iridium by means of photon irradiation. We grow thin films of LiCl on top of graphene on Ir(111) and irradiate the system with soft X-ray photons, which leads to a cascade of physicochemical reactions.

Paper has the potential to dramatically reduce the cost of electronic components. In fact, paper is 10 000 times cheaper than crystalline silicon, motivating the research to integrate electronic materials on paper substrates. Among the different electronic materials, van der Waals materials are attracting the interest of the scientific community working on paper-based electronics because of the combination of high electrical performance and mechanical flexibility.

Article Synopsis
  • Laboratory astrochemistry simulates chemical and physical processes from various regions of the universe, focusing on cosmic dust grains in the interstellar medium (ISM) and their role in forming new chemical species.
  • The INFRA-ICE experimental station can mimic the cold conditions of the ISM and is integrated with a larger setup called Stardust, which studies the entire life cycle of cosmic dust from creation in stars to interaction in space.
  • Recent results on ultraviolet photochemistry of undecane at 14 K highlight the relevance of aliphatics, which have been detected in the comet 67P/Churyumov-Gerasimenko and are crucial to understanding cosmic dust composition.
