Nucleation Process

An external electric field can affect the growth dynamics of croconic acid (CA) films, especially the heterogeneous nucleation process, as evidenced by the shift of temperature dependence of the nucleation rate in the electric field.

New Phase

The article deals with the nucleation rate in the development of the atomic theory. The expression for the calculation of heterogeneous nucleation rate in adsorbed layers in an external electric field, which allows for the stability criterion nucleus of a new phase. For example, the values of nickel electrocrystallisation nucleation rate in the development of the atomic theory and the classical theory of nucleation. A comparison with the experimental values. It is shown that at high overvoltage at the cathode developed atomic theory gives values of the nucleation rate closer to the experimental.

Domain Inversion

It is demonstrated that high-intensity illumination with an Ar-ion laser beam can generate domain-inversion patterning in KNbO3crystals. With a special laser-assisted micro-manipulation platform, direct patterning of domain-inversion structures without applying any external electric field can be carried out. The domain-nucleation process has been observed, and the process is purely optical, localized, and potentially controllable both in size and in orientation.

Functional Theory

Background: Boron Nitride Nanotubes (BNNTs) have recently emerged as an interesting field of study, because they could be used for the realization of developed, integrated and compact nanostructures to be formulated. BNNTs with similar surface morphology, alternating B and N atoms completely substitute for C atoms in a graphitic-like sheet with nearly no alterations in atomic spacing, with uniformity in dispersion in the solution, and readily applicable in biomedical applications with no obvious toxicity. Also demonstrating a good cell interaction and cell targeting. Aim and Objective: With a purpose of increasing the field of BNNT for drug delivery, a theoretical investigation of the interaction of Melatonin, Vitamin C, Glutathione and lipoic acid antioxidants using (9, 0) zigzag BNNTs is shown using density functional theory. Methods: The geometries corresponding to Melatonin, Vitamin C, Glutathione and lipoic acid and BNNT with different lengths were individually optimized with the DMOL3 program at the LDA/ DNP (fine) level of theory. Results: In the presence of external electric field Melatonin, Vitamin C, Glutathione and lipoic acid could be absorbed considerably on BNNT with lengths 22 and 29 Å, as the adsorption energy values in the presence of external electric field are considerably increased. Conclusion: The external electric field is an appropriate technique for adsorbing and storing antioxidants on BNNTs. Moreover, it is believed that applying the external electric field may be a proper method for controlling release rate of drugs.
