“…An increase in D was observed not only with the addition of small amounts (μg and mg) of NPs to pure solvents (water, ethanol, and ethylene glycol) [26,37], but also with an increase in the nanophase concentration. This has been observed in an acrylic resin [25], water [41], ethanol and ethylene glycol [37].…”

The growing interest in heat-conducting nanofluids requires highly sensitive methods for analyzing thermal properties. Thermal-lens spectrometry, despite its advantages over classical methods, does not have a general approach to measuring and interpreting results for dispersed systems. In this paper, by the example of nanofluids of silicon oxide in water in a wide range of concentrations and sizes, the selection of measurement parameters for transient and steady-state thermal lensing is justified, and the interpretation of the results of thermal diffusivity measurements is substantiated. The features of measurements of thermal diffusivity by thermal lens spectrometry under stationary state for dispersed systems are considered. Using this approach, it is possible to detect and distinguish thermal effects with high accuracy. For dispersions of silicon oxide, with increasing concentration, the thermal diffusivity passes through a minimum. Silicon oxide dispersions can be used both as a coolant or as a heat-removing liquid by selecting the particle size and concentration.

“…A broad single absorption band was observed between 300-600 nm corresponds to presence of larger size, spherical and polydisperse AgNPs [19]. Figure 3b showed the absorption spectrum of C. baccatum fruit extract and peak observed at 300-600 nm can be assigned to its bioactive compounds such as capsaicinoids, phenolic compounds, carotenoids, protein/enzymes, polysaccharides, amino acids and vitamins [19,22,27].

“…Surface functionalization of AgNPs having different morphology alters the physico-chemical properties [19,20], which may play a crucial role in various bioengineering applications [9,21]. Recently, different MNPs were synthesized by using Capsicum species of different geographical origin including C. baccatum [3] and C. annuum fruit [22] for AuNPs [3], C. annuum [23][24] and C. frutescence fruit for AgNPs [25], C. annuum leaves for AuNPs [26], C. annuum var annuum (Jalapeño Chili) for AgNPs [27], Capsicum annuum for ZnO nanoparticles [28,29], etc has been already reported.…”

Scope of green chemistry in nanobiotechnology is generating research interest in the development of an ecofriendly synthesis of nanoparticles and their wide range of applications in engineering and biomedical field. In the present study, we report a simple and ecofriendly phytosynthesis of silver nanoparticles (AgNPs) using Ají amarillo chilli (Capsicum baccatum L.) fruit, where phytoconstituents of C. baccatum behaves as a reducing as well as a stabilizing agent. The phyotsynthesized AgNPs were characterized through various spectroscopic and microscopic techniques. The produced AgNPs showed surface plasmon resonance (SPR) at λmax = 458 nm and stable for 10 days, confirmed by UV-vis spectroscopy. Transmission electron microscopy (TEM) explained that produced AgNPs were almost spherical in shape with average size of 10-30 nm along with small aggregation. Aggregation of AgNPs was indicated in the dynamic light scattering (DLS) analysis. The results also demonstrate that as-synthesized AgNPs are low-cost and rapid alternative as optical chemical sensors and showed >50% H2O2 quenching/ sensing activity for 15 mins at room temperature.

“…This study reported that the MONPs showed good antioxidant and antifungal properties. Luna-Sanchez et al 199 prepared silver nanoparticles using Jalapeno chili extract. The reduction of the silver nanoparticles was achieved by the flavones and flavanols present in the extract of Capsicum annuum var annuum.…”

View full text Add to dashboard Cite

Nanofluids are an emerging class of heat transfer fluids that are engineered by dispersing nanoparticles in conventional fluids. They represent a promising, multidisciplinary field that has evolved over the past two decades to provide enhanced thermal features, as well as manifold applications in thermal management, energy, transportation, MEMs and biomedical fields. Fundamentals and Transport Properties of Nanofluids addresses a broad range of fundamental and applied research on nanofluids, from their preparation, stability, and thermal and rheological properties to performance characterization and advanced applications. It covers combined theoretical, experimental and numerical research to elucidate underlying mechanisms of thermal transport in nanofluids. Edited and contributed to by leading academics in thermofluids and allied fields, this book is a must have for those working in chemical, materials and mechanical engineering, nanoscience, soft matter physics and chemistry.
