Nanocellulose is regarded as a green and renewable nanomaterial that has attracted increased attention. In this study, we demonstrate that nanocellulose materials can exhibit high thermal conductivity when their nanofibrils are highly aligned and bonded in the form of filaments. The thermal conductivity of individual filaments, consisting of highly aligned cellulose nanofibrils, fabricated by the flow-focusing method is measured in dried condition using a T-type measurement technique. The maximum thermal conductivity of the nanocellulose filaments obtained is 14.5 W/m-K, which is approximately five times higher than those of cellulose nanopaper and cellulose nanocrystals. Structural investigations suggest that the crystallinity of the filament remarkably influence their thermal conductivity. Smaller diameter filaments with higher crystallinity, that is, more internanofibril hydrogen bonds and less intrananofibril disorder, tend to have higher thermal conductivity. Temperature-dependence measurements also reveal that the filaments exhibit phonon transport at effective dimension between 2D and 3D.

The International Conference on Polygeneration (ICP) have established as a highly reputed conference series for leading scholars in the field of energy conversion with more than one form and its related research fields. The energy supplied to the system could be provided by conventional sources, including fossil fuels, renewable energy or a combination of them. ICP2019 is the 5th installment following successful events in Cuernavaca, Mexico (ICP2017), Chennai, India (ICP2015), and Tarragona, Spain (ICP2013, ICP2011). ICP2019 was held in Fukuoka, Japan from May 15 to 17, 2019. The event was highly successful where leading energy experts presented 4 plenary lectures, 2 panel sessions, 16 oral sessions, a poster session with 120 contributed papers in total. This time, ICP2019 devoted a Special Session in the memory of Prof. Shigeru Koyama, a worldrenowned scientist from Japan. ICP conference series has been reputed for quality technical and scientific papers that are published in impactful journals obtaining respectable citations. There is no exception for the ICP2019 in maintaining an excellent tradition. Twelve technical papers that address key issues in thermal engineering were selected for this Special Issue. The first 3 papers by Perera et al., Lee et al., and Takezato et al., focus on the performance of the refrigerants. The next 4 papers by Desai et al., Akhter et al., Jahan et al., and Naik et al. investigate the performance of the materials for cooling, adsorption, and drying systems. The eighth and ninth papers by Irshad et al. and Looi et al. deal with the air duct system for tropical climate. The tenth and eleventh papers by Gajghate et al. investigate the pool boiling heat transfer. The twelfth paper by Honzawa et al. focuses on the ammonia combustion system for low-carbon emission. We sincerely hope that this exchange of knowledge and experience during ICP2019 resulted in an enhanced global collaboration between academics and researchers to further advance the interrelated fields of refrigerants, materials for heat transfer systems, boiling heat transfer, and low-emission combustion. ICP2019 simply serves its primary objective which is to form a platform for exchanging knowledge and experience promoting global collaboration. In doing so, international experts have actively participated to further advance the interdisciplinary research fields of polygeneration. Our gratitude is expressed to the supports from the conference co-organizers, International Institute for Carbon-Neutral Energy Research (WPI-ICNER), Kyushu University, Research Center for Next Generation Refrigerant Properties (NEXT-RP), Kyushu University. We would like to extend our sincere appreciation to WPI-ICNER and NEXT-RP, Kyushu University for their support. We strongly recognize significant contributions by all authors without whom ICP won’t be in existence. We especially record our gratefulness to the reviewers who have provided their expertise and strong effort in reviewing the manuscripts from the conference stage to special issue edition. Last but not least, we are indebted to the Editor-in-Chief of Heat Transfer Engineering Journal, Prof. Afshin J. Ghajar, for his careful editing of the final versions of the papers published in this special issue and for his dedication and willingness to publish this series of special issues highlighting the current research going on worldwide.

In this work, we experimentally investigated the solidification behavior of functionalized graphene-based phase change nanocomposites inside a sphere. The influence of graphene nanoplatelets on thermal transport and rheological characteristics of the such nanocomposites were also discussed. We adopted the covalent functionalization method to prepare highly stable phase change nanocomposites using commercially available phase change material (PCM) OM08 as the host matrix and graphene nanoplatelets (GnPs) with 0.1, 0.3, and 0.5 volume percentage as the nano inclusions. We report a maximum thermal conductivity enhancement of ~102 and ~46% with 0.5 vol% in the solid and liquid states, respectively. Rheological measurements show that the pure PCM shows Newtonian behavior, whereas the inclusion of GnPs leads to the transition to non-Newtonian behavior, especially at lower shear rates. Viscosity of the nanocomposite increases with an increase in the volume fraction of GnP. For 0.5 vol% of GnPs, maximum increase in viscosity was found to be ~37% at a shear rate of 1000 s−1. Time required for complete solidification decreases with the loading of GnPs. Maximum reduction in solidification time with 0.5 vol% of GnPs was ~40% for bath temperature of −10°C.
