The growth of 2D materials through chemical vapour deposition has been highly optimised in recent years to produce high quality crystalline films, however, a key problem and yet addressed bottleneck is the integration of these 2D materials into fabrication process flows. Here we focus on dry transfer as a simple and flexible method of 2D material application. By treating the crystallographic...

Two-dimensional (2D) sulfides such as MoS2, SnS2 or SnS have exciting application potential in catalysis, energy storage/conversion and electronics. Liquid phase exfoliation (LPE) is a facile way to obtain 2D sulfides in a potentially scalable way. Current LPE recipies however often rely on organic media ("solvents") that are toxic and suffer from high boiling points and are thus hard to...

Graphene is considered to be largely impermeable to gases, ionic species and
liquids making it in principle a promising and ultimately thin corrosion barrier.
We aim to grow high quality graphene coatings, on di?erent modern steels by
catalytic chemical vapor deposition (CVD). This remains an unresolved chal-
lenge, mainly due to the large parameter space in balancing CVD...

Two-dimensional (2D) oxides have recently attracted a lot of attention due to their unique electronic and transport properties. In this work, we apply density functional theory (DFT) calculations using local (LDA) and fully nonlocal exchange-correlation functionals (HSE06/PBE0) to investigate the effect of the number of layers on the structural and electronic properties of litharge SnO and...

α-MoO3 is a promising material for use in charge extracting layers within optoelectronic devices, due to its wide gap and deep work-function, characteristics that makes it an established constituent of “hole transporting layers” in last generation solar cells and light emitting diodes. This material possesses a layered structure that make it also suitable for mechanical exfoliation to...

Liquid metals are functional materials that play an important role in many research fields, including medicine, electronics and synthesis of new materials [1]. Modern liquid metals, which are alloys and elements liquid at room temperature, are based on the non-toxic and safe to handle element gallium [2]. Gallium and it's alloys exhibit many unique properties such as a high degree of...

Porous thin films from liquid exfoliated WS2 2D nanosheets
2D transition metal dichalcogenides (TMDs) are emerging semiconductors of great interest for a number of applications, ranging from (opto)electronics to biomedicine. Liquid exfoliation is a highly scalable method for...

Rare Earths (RE) have the prospect of being used in clean technologies, such as, for example, wind turbines and hybrid vehicles, in addition to strategic segments in communication and oil, which are limited by rare earth availability. The disadvantage of rare earth processing is related to rapid oxidation and higher reactivity of transition metals. In that case, (RE)-based powders must be...

Almost fully dense silicon carbide composites with 1 vol.% Y2O3–Sc2O3 sintering additives and with different amount of graphene nanoplatelets (GNPs) from 1 to 10 wt. % or 1 wt. % of graphene oxide (GO) were sintered in rapid hot press (RHP) at 2000°C for 30 min with a pressure of 50 MPa under nitrogen atmosphere.
Thermal and electrical conductivity were investigated as a function of amount of...

Graphene is a 2D single layer of hybridized sp² carbon atoms covalent bond in a hexagonal structure (honeycomb type). Due to their unique mechanical properties, such as Young's modulus of 1.0 TPa and tensile strength of 130 GPa, graphene has become an attractive candidate as a structural reinforcement for polymer nanocomposites [1], [2]. However, the production of pure graphene is...
