Twin-plane reentrant edge growth of rhombohedra boron suboxide platelets

Cyclic formation of boron suboxide crystallites into star-shaped nanoplates

“…Different nanostructural forms of B 6 O have also been widely synthesized and studied by many material researchers, such as nanowires [8], nanoplatelets [9] and nanofilms [10,11]. Probably the most remarkable structure is icosahedral particles of boron suboxide.…”

“…A similar technique of manipulating crystal morphology by controlling the processing condition has also been applied in the synthesis of boron carbide nanoparticles and nanoflakes [31]. An in-depth study would have to be undertaken to better understand the crystal growth mechanism between B 6 O icosahedral particles [12], B 6 O starshaped nanowires [8], B 6 O platelets [9] and the current star-shaped B 6 O nanoplates.…”

Embedding Ba Monolayers and Bilayers in Boron Carbide Nanowires

“…For example, prior studies showed that the formation of an impurity-based surficial “amorphous” films 1 (SAFs, as a type of surface complexions, where the term “complexion” refers to the thermodynamic equilibrium state of an interface; noting that this type of complexion is neither completely crystalline nor fully amorphous despite of being named as SAFs 1 ) - can change faceted particles into nanospheres 2 or stabilize anisotropic morphology 3 . Specifically, we have recently demonstrated that adding barium oxide as an additive along with the iron-rich catalyst can help to control the growth of B-C-O nanowires 4 and nanoplatelets 5 6 7 to achieve unique morphologies and high yields; here, we further demonstrated that the controlled anisotropic growth is related to the formation of barium-enriched surface complexions.…”

Cyclic twinning and internal defects of boron-rich nanowires revealed by three-dimensional electron diffraction mapping

“…29,30 The possible presence of the are (or the diffuse scattering) has been known because they, for example, are believed to contribute to the forbidden reections in the zone-axis diffraction patterns. 31,32 The advantage of the 3D diffraction dataset is that it allows us to analyze the intensity of the diffuse scattering more quantitatively. For example, the pure shape effect can be easily simulated.…”
