What recent developments have been made in the field of nucleation in polymeric biomaterials?4 answersRecent developments in the field of nucleation in polymeric biomaterials have focused on understanding the complex pathways of biopolymer self-assembly. These pathways involve a two-step mechanism where monomers condense to form metastable intermediates, which then convert to stable polymers through conformational rearrangement. The dynamics of conversion events play a crucial role, as they occur on comparable timescales to condensation and growth, impacting the accumulation rate of stable phases. Mathematical models have been proposed to explicitly account for simultaneous assembly and conversion, providing insights into the kinetics of nucleation intermediates and stable phases in polymeric systems. These advancements offer a deeper understanding of nucleation processes in polymeric biomaterials, with implications for various biomedical applications.
What is filmmaking?5 answersFilmmaking is a versatile method that spans various disciplines, from art to public health research. It involves creating visual content through a collaborative process, where participants are trained to produce, analyze, and present films to address research questions. In the realm of art, filmmaking has been utilized as a medium for experimental practices, particularly during the avant-garde movements of the 1960s and 1970s, contributing to the redefinition and expansion of visual arts by exploring the material, technological, and disciplinary aspects of the medium. Additionally, in the context of light emitting devices, a method for producing films with high efficiency involves using specific metal complexes stored under light shielding to form a film, showcasing the technical aspects of filmmaking in a different domain.
What is the nucleation thermodynamics of a phase transition?5 answersThe nucleation thermodynamics of a phase transition refers to the process by which a new phase is formed from a metastable phase. Nucleation is a non-equilibrium physical mechanism that involves the formation of the first seeds of the new phase. It is a fundamental process that occurs in various scientific and technological phenomena, such as nuclear phenomena, biological assembly, and galaxy formation. The exact treatment of nucleation in small systems is challenging, as there are more gradual changes instead of sharp discontinuities observed in macroscopic systems. However, recent studies have shown that nucleation processes between solid-solid phase transitions involve a two-step diffusive pathway, with liquid nuclei playing a crucial role. The dynamics of nucleation can be described using continuous Fokker-Planck equations, which allow for the treatment of non-isothermal effects and volume corrections. Overall, understanding the nucleation thermodynamics of phase transitions is essential for predicting and controlling the kinetics of these processes.

Is there any study mention using nucleases against c. acnes or p. acnes biofilms?5 answersNucleases have been studied for their potential use against biofilms of C. acnes and P. acnes. Shih et al. investigated the effects of nicotinamide (NAM) on C. acnes biofilms and found that NAM alone decreased biofilm formation and increased degradation. Barroso et al. evaluated the photodynamic inactivation of P. acnes biofilms using different concentrations of hypericin photosensitizer and low-level laser energy, and observed a reduction in biofilms after treatment. Varin-Simon et al. compared C. acnes biofilm formation in static and dynamic models and highlighted the importance of selecting a relevant biofilm model for effective antibiofilm strategies. Mongaret et al. studied the behavior of commensal and bone and prosthesis infection (BPI) C. acnes strains in the bone environment and observed an increase in biofilm formation after internalization by osteoblast-like cells for commensal strains. Burgess et al. developed pharmaceutical compositions for biofilm disruption and prevention, including the use of microbial nucleases.
How heat flux affect the bubble dynamics of nucleating bubble?3 answersThe heat flux has a significant effect on the dynamics of nucleating bubbles. Higher heat flux leads to shorter nucleation time and faster bubble growth. The nucleation time of bubbles is reduced when the micro electrode has a higher heat flux, as it produces more thermal energy. Additionally, higher heat flux results in faster bubble growth. The heat transfer rates during coalescence are mainly influenced by transient conduction due to the movement of the contact line during bubble interactions. The heat flux spikes generated by fast evaporation of the liquid layer trapped between two bubbles have less influence due to their short duration and small influence area. Overall, the heat flux affects both the nucleation time and growth of bubbles, with higher heat flux leading to shorter nucleation time and faster bubble growth.
