“…Correspondingly, HPH is suitable for use to directly produce a wide variety of dispersions and has been demonstrated as an effective technique for dispersing and potentially modifying nanomaterials (Azoubel and Magdassi, 2010;Li et al, 2019;Schlüter et al, 2014;Tölle et al, 2012). Many studies have reported successful use of HPH as a processing step to produce advanced materials such as graphene films and inks (Tölle et al, 2012), polymer composites incorporating nanomaterials for improved mechanical, thermal and electrical properties (Appel et al, 2012;Chatterjee et al, 2012;Clausi et al, 2020;Shayganpour et al, 2019;Wu et al, 2021;Xu et al, 2020), and nanofluids which will be discussed.…”

Despite being a technology of several decades, high pressure homogenization (HPH) remains widely used in food and pharmaceutical industries, often as an essential unit operation in liquid product processing. Continual advances in the technology are made on multiple fronts, on equipment innovations by the manufacturers, new applications by users and advances in process understanding by multidisciplinary scientists alongside subject matter experts amongst industry practitioners. While HPH is comparatively simple conceptually, the homogenization process involves complex engineering physics which is influenced by the varied processing conditions and highly diverse inputs with each use-case requiring its own treatment. The successful application of a HPH process indubitably requires practitioners to draw upon insights from multiple domains and the optimization for each case. Thus, this timely review aims to outline the more recent trends and advancements in HPH process understanding and novel applications involving HPH from both academic and industrial perspectives.

“…Surface roughness of the stone substrates before and after the application of the coating was investigated by 3D Optical Profilometry. Different magnifications, ranging from 2.5× to 20× were used corresponding to a Z profile resolution ranging from 25.0 μm to 0.5 μm respectively [52]. Moreover, the adherence of the coating to the stone surface was evaluated by performing a peeling test using Scotch® MagicTM tape (3 M).…”

“…Even though single layer graphene has excellent thermal conductivity of about 5300 W/m K [45], outperforming other nanocarbon materials [50], the GnPs are more like graphite flakes with much lower thermal conductivity [51,52]. With proper dispersion, alignment and using specific polymer matrices that can tolerate large concertation of GnPs without compromising flexibility and workability, conformal TIM films or coatings can be produced with thermal conductivities approaching 10 W/mK [53][54][55]. Hybrid systems can help reduce bulk contact resistance between the polymer and a particular filler.…”

has several attractive properties such as corrosion resistance, catalytic activity, sensing properties, and magnetic features but also a room-temperature stable thermal conductivity of about 16 W/m K. Its use in polymer-matrix composites as a thermal performance enhancer is rather uncommon. In this study, hematite and graphene nanoplatelet (GnP) hybrids in a rubbery latex matrix were prepared and their thermal properties were characterized. The hybrids were mechanically stabilized into freestanding films by hot-pressing them into a porous cellulosic membrane. Optimization of total filler concentration and the α-Fe2O3/GnP ratio yielded thermal interface material (TIM) films with thermal conductivity of 8.0 W/mK. Infrared measurements showed that the TIMs significantly improved heat sink cooling and demonstrated rapid heat transfer in a system simulating stacked up electronic packing.
