“…Our results suggest that the ML-assisted RHEED analysis could be developed into an automatic validation method for investigating ultrathin 2D materials films, and it is complementary to other surface analysis tools [ 7 , 38 , 39 ]. Furthermore, this method can be applied to analyze the thin-film growth of other 2D materials, such as 2D chalcogenides, 2D MXenes, 2D oxides, and hexagonal boron nitrides [ 40 – 43 ].…”

In situ reflective high-energy electron diffraction (RHEED) is widely used to monitor the surface crystalline state during thin-film growth by molecular beam epitaxy (MBE) and pulsed laser deposition. With the recent development of machine learning (ML), ML-assisted analysis of RHEED videos aids in interpreting the complete RHEED data of oxide thin films. The quantitative analysis of RHEED data allows us to characterize and categorize the growth modes step by step, and extract hidden knowledge of the epitaxial film growth process. In this study, we employed the ML-assisted RHEED analysis method to investigate the growth of 2D thin films of transition metal dichalcogenides (ReSe2) on graphene substrates by MBE. Principal component analysis (PCA) and K-means clustering were used to separate statistically important patterns and visualize the trend of pattern evolution without any notable loss of information. Using the modified PCA, we could monitor the diffraction intensity of solely the ReSe2 layers by filtering out the substrate contribution. These findings demonstrate that ML analysis can be successfully employed to examine and understand the film-growth dynamics of 2D materials. Further, the ML-based method can pave the way for the development of advanced real-time monitoring and autonomous material synthesis techniques. Graphical Abstract

“…Transition metal carbides, nitrides and carbonitrides (MXene) are 2D materials that can be incorporated into metal and ceramic matrices to offer favourable properties. 49 MXene membranes have very similar structure to GO membranes, with hydroxyl, fluoro, and oxide groups creating interlayer pathways resulting in the high H2 permeability and selectivity. 29 The use of high toxicity hydrogen fluoride (HF) in MXenes manufacture and their susceptibility to oxidation appear to be just two of numerous issues that must be overcome to implement them effectively.…”

“…7,8 Nonetheless, some shortcomings of PCMs make them impossible to use alone 9,10 and an effective solution to prevent their leakage is to package them with support materials. 11 PCMs can be well confined in the porous matrices by capillary forces and intermolecular forces, 12 which mainly including polymers, 13 oxides, 14 carbons, 15 biomass, 16 ceramics, 17 etc. Usually, porous biomass materials are nontoxic and biodegradable, which greatly satisfy the requirement of green energy when using them as support materials for PCMs.…”

In order to improve the applicability in some extreme environments, a large number of research efforts have been conducted using carrier materials loaded with phase-change materials (PCMs). Wheat bran (WB), a kind of agroforestry waste and inexpensive biomass, is often ignored and discarded and further becomes a serious environmental threat. In this work, an effective high-value utility of WB in the field of composite PCMs was designed. First, briefness and efficient alkali-treated methods were adopted to control the degree of starch gelatinization of WB and the components within WB were entangled to form a threedimensional network, and then the alkali−wheat bran aerogels (AWBs) were obtained via freeze-drying method. The AWBs were utilized as biomass carriers to incorporate polyethylene glycol (PEG), and the composite PCMs (AWBs-PEG) were fabricated. The morphological structure and the properties of antileakage, thermal storage, thermal stability, and temperature regulation of the fabricated composite PCMs were studied. The results indicated that AWBs exhibited excellent performances including good antileakage and high PEG adsorption rate (up to 86.2%). The melting and crystallization enthalpy values of AWBs-PEG could reach 153.5 J/g and 134.3 J/g, respectively. It could also be found that AWBs-PEG possessed a superior thermal cycle stability, thermal reliability, and temperature regulation ability. The integration of AWBs-PEG with temperature sensitive ink demonstrated an exciting color-change buffering property. It would provide an innovative direction for solar thermal energy storage, thermal infrared stealth, advanced smart textiles, and other research fields.
