Nano-Thermal Analysis of Defect-Induced Surface Pre-Melting in 2D Tellurium

Thermal properties, such as thermal conductivity, heat capacity, and melting temperature, influence the efficiency and stability of two-dimensional (2D) material applications. However, existing studies on thermal characteristics—except for thermal conductivity—are insufficient for 2D materials. Here, we investigated the melting temperature of 2D tellurium (2D Te) using the nano-thermal analysis technique and found anomalous behavior that occurs before the melting temperature is reached. The theoretical calculations present surface pre-melting in 2D Te and Raman scattering measurements suggest that defects in 2D Te accelerate surface pre-melting. Understanding the pre-melting surface characteristics of 2D Te will provide valuable information for practical applications.

Chaos & Creation: Adam van Vianen's Gilt Ewer

With its bizarre melting surface and the solid forms emerging out of it, this seventeenth-century ewer by the goldsmith Adam van Vianen arouses curiosity and invites investigation. Commissioned in memory of his brother, Paulus van Vianen, who largely developed the auricular style perfected in it, this ewer is a work that rewards exploration – the more you investigate the more there is to see and be delighted by. The incredibly complicated construction of this piece attests to evident careful design and intent in every form in it, raising the question as to their individual meaning and the message they convey as a whole. This study answers the ewer’s call to curiosity by investigating the meanings of the individual forms and the commonalities that connect them as a group. The result is a surprising journey into the world of seventeenth-century alchemy, natural philosophy and Kunstkammers. Research into the iconographical meaning of both the visible forms and the folding surface in the context in which it was created has led the author of this analysis to conclude that the ewer functions as an allegory for the process of artistic creation, visualizing the artist bringing life into the world out of chaos.

Analysis of modified Fourier law and melting heat transfer in a flow involving carbon nanotubes

The dynamics of non-Newtonian liquids flow along with suspension of nanoparticles are pretty exciting with many industrial applications. In view of this, we examined Darcy-Forchheimer two-dimensional carbon nanotubes flow in light of a melting surface with warm nonlinear radiation, Cattaneo-Christov heat flux and slip condition. Similarity transformations are utilized to deal with the problem equations for non-dimensionality. Runge-Kutta-Felberg-45 method by adopting shooting scheme is applied for the simulation of the demonstrated equations. The thermal framework is investigated for all the implanted parameters whose impacts are appeared through various graphs. There exist fascinating outcomes because of the impacts of various constraints on various profiles. Results reveals that, velocity and corresponding thickness of the boundary layer declines for rising values of Forchheimer parameter and porosity parameter. Moreover, rate of declination of velocity gradient in MWCNT-water stream is slower than SWCNT-water stream. Also, inclined values of melting parameter display a diminishing pattern for the temperature field. Further, rate of declination in heat transfer of SWCNT-water stream is faster than MWCNT-water stream.
