“…Two strategies were used. First, a surface coating of nano-dimensioned TiC was applied to the diamond particles (TiC coatings have been proven to enhance the metal-diamond interface thermal conductance for metals such as Al [12,13] and Cu [14][15][16]). Second, at the micro-/meso-scale, a proper design route based on blending different predictive models was used to select the most adequate combinations of bimodal diamond particle mixtures.…”

“…Oxygenated diamond samples have roughly thermal interface conductance with Al four times higher than hydrogen-treated samples [20]. Different metallic coatings have been used to effectively increase the interfacial thermal conductance [21][22][23]. While some of the progresses detailed above are ultimately positive, some authors have identified the need of enhancing the intrinsic thermal conductivity of the diamond as the most promising direction of progress [9].…”

As a service to our customers we are providing this early version of the manuscript. The manuscript will undergo copyediting, typesetting, and review of the resulting proof before it is published in its final form. Please note that during the production process errors may be discovered which could affect the content, and all legal disclaimers that apply to the journal pertain. TC is mainly governed by the Al-diamond interface characteristics, which are determined by a proper control exerted through processing conditions. Albeit a very low cost and low quality diamond is used, a high value of 667 W/mK has been measured for Al/diamond composites produced under optimized processing conditions. Values above 740 W/mK are reported for the best diamond quality explored in this work. These experimental results, which assign the control over TC mainly to the interface conductance, suggest that many of the limiting values of TC reported in literature for the different explored metal-diamond systems, need to be reconsidered by proper precise control of interface evolution.

The melting and solidification of nanowires

A mathematical model is developed to describe the melting of nanowires. The first section of the paper deals with a standard theoretical situation, where the wire melts due to a fixed boundary temperature. This analysis allows us to compare with existing results for the phase change of nanospheres. The equivalent solidification problem is also examined. This shows that solidification is a faster process than melting; this is because the energy transfer occurs primarily through the solid rather than the liquid which is a poorer conductor of heat. This effect competes with the energy required to create new solid surface which acts to slow down the process, but overall conduction dominates. In the second section, we consider a more physically realistic boundary condition, where the phase change occurs due to a heat flux from surrounding material. This removes the singularity in initial melt velocity predicted in previous models of nanoparticle melting. It is shown that even with the highest possible flux the melting time is significantly slower than with a fixed boundary temperature condition.
