Summary: Liquid-phase exfoliation of 3D solid precursors into ultra-thin sheets of layered materials has gained global interest due to its simplicity and industrial applicability. The characteristics of exfoliated graphene depend on the processing technique and properties of the starting precursor materials. This study explored the role of initial 3D precursors in creating 2D materials by exfoliating graphite flakes of different sizes, and assessed the morphology and defects of the resulting nanosheets.

Summary: 3D printing technologies combined with chemical vapor deposition can be used to fabricate new hybrid materials with tunable properties. The thickness and crystallinity of graphene-based coatings can be controlled by altering the parameters of chemical vapor deposition. Transmission electron microscopy confirms the successful growth of nanocrystalline graphene layers on 3D printed α-Al2O3 substrates, resulting in fully-connected and highly conductive pathways. In terms of thermal conductivity, specimens decorated with graphitic coatings exhibit higher thermal conductivity compared to bare ceramic scaffolds.

Summary: In this paper, a new method of tuning the electrical conduction in aluminum nitride-based ceramics by incorporating graphene nanoplatelets (GNP) was reported. Multiple preparation was used to save time and energy, with three samples prepared per cycle. By adjusting the amount of GNP and the exfoliation method, a 10 orders of magnitude increase in electrical conductivity was achieved compared to commercial aluminum nitride. This work promotes the development of novel multifunctional ceramic composites for Power Electronics applications.

Summary: The development of inkjet-printed 2D crystal inks allows for the printing of different 2D materials to form vertical heterostructures. This study focuses on the characterization of inkjet-printed MoTe2 nanosheets, which exhibit both semiconducting and metallic phases. Photodetectors based on MoTe2/graphene and WS2/graphene heterostructures show high responsivities at specific wavelengths. The inkjet printing technique provides a new method for the fabrication of flexible optoelectronic devices based on transition metal dichalcogenide-graphene heterostructures.

Summary: This study introduces a new concept of physical unclonable functions (PUFs) using reduced graphene oxide (GO) materials. Two types of GO, HGO and PGO, are used to create a disordered conductivity distribution. PGO becomes graphene-like after room-temperature chemical reduction. The blending of these two materials generates a random mixture that can generate highly unpredictable electrical signals, serving as ideal security keys with strong randomness and uniqueness. The optimized PUF device based on this approach demonstrates excellent performance in generating secure keys.
