Modelling Nuclear Morphology and Shape Transformation: A Review [PDF]

Membranes, 2021
As one of the most important cellular compartments, the nucleus contains genetic materials and separates them from the cytoplasm with the nuclear envelope (NE), a thin membrane that is susceptible to deformations caused by intracellular forces ...

Gallium-Doped Hydroxyapatite: Shape Transformation and Osteogenesis Activity [PDF]

Molecules, 2023
In this study, we employed a chemical precipitation method to successfully synthesize nanoparticles of gallium-doped hydroxyapatite (Ga-HAp). The microstructure of Ga-HAp was precisely tailored by modulating the concentration of gallium ions.

Insights into nanoparticle shape transformation by energetic ions [PDF]

Scientific Reports, 2023
Shape modification of embedded nanoparticles can be achieved by means of swift heavy ion irradiation. During irradiation, the particles elongate and align with the direction of the ion beam, presumably due to nanometer-scale phase transitions induced by ...

Additive manufacturing of flexible polymer-derived ceramic matrix composites

Virtual and Physical Prototyping, 2023
It remains challenging to broaden the application fields of ceramics, largely because the hardness and brittleness of ceramics mean that they cannot undergo shape reconfiguration.
