“…Silica produced from RH at a temperature of 500 to 650°C with a combustion time of 2.5 to 6 h is predominantly amorphous, while crystallinity is achieved when the annealing temperature rises above 700°C. While crystalline silica is used in ceramics, steel, thermal insulator and refractory bricks (Prasad et al, 2001) and in the concrete industry (Kumar et al, 2013), amorphous silica finds a much wider range of applications in concrete production (Kannan, 2018), pulp industry (Chen et al, 2017), laboratory glassware (Shi et al, 2017), adsorbents (Pivovarov, 2008) and drag delivery carriers (Mitran et al, 2018). Various value-added products, such as aerogel (Tang and Wang, 2005), silica carbide (Niyomwas, 2009), porous carbon (Satayeva et al, 2018), zeolites (Ng et al, 2015) and other products can be obtained by using the silica produced from RH (Shen et al, 2014).…”

“…Today, investigating heat transfer in the vicinity of colloidal nanoparticles, i.e nanoparticles surrounded by water, is of great importance for various applications [1][2][3][4]. These applications include on one hand nanoparticle based cancer treatments, and on the other hand, the thermal transport properties of nanofluids, which are suspensions of metallic nanoparticles in water and are known to display enhanced thermal conductivity [5][6][7][8].…”

Heat transfer between a silver nanoparticle and surrounding water has been studied using molecular dynamics (MD) simulations. The thermal conductance (Kapitza conductance) at the interface between a nanoparticle and surrounding water has been calculated using four different approaches: transient with/without temperature gradient (internal thermal resistance) in the nanoparticle, steady-state non-equilibrium and finally equilibrium simulations. The results of steady-state non-equilibrium and equilibrium are in agreement but differ from the transient approach results. MD simulations results also reveal that in the quenching process of a hot silver nanoparticle, heat dissipates into the solvent over a length-scale of ~ 2nm and over a timescale of less than 5ps. By introducing a continuum solid-like model and considering a heat conduction mechanism in water, it is observed that the results of the temperature distribution for water shells around the nanoparticle agree well with MD results. It is also found that the local water thermal conductivity around the nanoparticle is greater by about 50 percent than that of bulk water. These results have important implications for understanding heat transfer mechanisms in nanofluids systems and also for cancer photothermal therapy, wherein an accurate local description of heat transfer in an aqueous environment is crucial.

“…Details of the extraction methodology, effect of process pretreatment on the quality of the silica product, effect of post-processing steps, and environmental aspect of the silica extraction methodologies have been reported by several groups of authors [29][30][31][32][33][34][35][36][37][38][39][40][41][42]. Amorphous silica is mostly consumed as laboratory glass ware [43], in paper and pulp industry [44], drag delivery carriers [45], while crystalline silica typically find uses in ceramics, steel, thermal insulator, and refractory bricks [47] and in the concrete industry [46], but its processing is not completely eco-friendly in nature because of its acid and alkali residues [48]. The preparation of bioactive glass ceramics based on isolated silica for drug delivery system has been reported by Chen et al [44].…”

Glass and ceramics have become an indispensable part of mankind, starting from home appliances to construction materials. Some common home appliance applications include the finest tableware, cook wares, and even many washing machines and driers. Glass ceramics are smart materials combining the properties of glass with the benefits of conventional sintered ceramics. "Glass ceramics" refers to a material that consists of one/more glass phases with one/more crystalline phases. These materials are typically manufactured, in a controlled nucleation and crystallization of any base glass. In brief, glass ceramic structure comprises an amorphous (glassy) phase with one/multiple embedded crystalline phases. The compositional variation of glass ceramics may design products of highly crystalline to more substantial glassy phase or transparent to opaque materials. To meet the specific requirements, compositional difference may be tuned to have material with zero thermal expansion, high toughness, resistance to thermal shock, and high impact resistance. According to the typical convention of base material, glass ceramics may be of either oxide based (silicate (SiO 2), borate (B 2 O 3), phosphate (P 2 O 5), and germinate (GeO 2)) or non-oxide based (chalcogenide, halide, and metallic). With wide variation of thermal and mechanical characteristics, glass has a broad range of applications like cooktops, toasters, clothes
