Rethinking the Cast Glass Mould

Although this mould technique is already used for metal castings, it remains still unexplored in the field of glass casting. Accordingly, this paper presents the first experimental findings at TU Delft of this mould technology: mould samples using different binders and treated with various coatings for surface finishing are tested in the high temperatures anticipated in glass (kiln-) casting.

Controlled Growth of Single‐Crystal Graphene Films

Over the past ten years, numerous efforts have been devoted to growing monolayer graphene samples with larger domain sizes and reduced GGBs. Following the first synthesis of centimeter‐sized graphene single crystal by Ruoff's group in 2013, 26 meter‐sized 27 and wafer‐sized 28 single‐crystal graphene samples have been successfully synthesized on Cu foil and Cu film substrates in 2017

Review of SiC crystal growth technology

2018/9/5The polycrystalline rim around the single crystal itself does not cause mechanical stress on the growing crystal because of the isotropic thermal expansion coefficient of 4H-SiC and 6H-SiC []. Nevertheless, the anisotropy of the free energy of the various SiC crystal surfaces causes an anisotropy of their growth rates which itself gives rise to poly-grains becoming ingrown into the single
