Carbon nanoparticles assisted energy transport mechanism in leaves: A thermal lens study

How graph features decipher the soot assisted pigmental energy transport in leaves? A laser-assisted thermal lens study in nanobiophotonics

“…[34,35] Hence, understanding about the constituent molecules taking part in the photosynthetic absorption process is essential. [17,[34][35][36] The ultra-violet-visible (UV-Vis) absorption spectrum of the samples extracted from the leaves sprayed with and without CNPs are recorded in a range of 300 nm-800 nm and is displayed in Fig. 2.…”

“…Initially, the soot is collected from the exhaust pipe of the public transport vehicles and purified by the liquid-phase oxidation method as described in one of our previous work. [17] The purified soot particles, rich in various nanocarbon allotropes, [25][26][27] are used for preparing the soot nanofluids. First, the carbon nanoparticles (CNPs) are mixed with distilled water in different proportions to prepare soot nanofluids of concentrations 0.20, 0.60, 1.25, 2.50, 4.00, and 5.00 g/l.…”

“…[10][11][12][13] Among them, the photothermal lens technique capable of detecting a temperature difference of about 10 −4 • C to 10 −6 • C is based on the transient heat propagation, thermal-induced refractive index variations, and creation of a thermal lens (TL) effect in the medium. [12,[14][15][16][17] The momentousness of the TL signal is that it reflects only the contributions of absorbed photons giving high signal to noise ratio making it a potential non-destructive technique for biological applications. [18,19] Recently, our group has reported the soot-assisted intrapigmental energy transport in leaves and seed matter using TL technique.…”

“…The hidden information of particle dynamics in the medium contained in the TL signal has also been unwrapped through the nonlinear time series and fractalysis. [17,[20][21][22] However, to the best of our knowledge, graph theory is seldom applied in the interdisciplinary branch of applied science -nanobiophotonics. [23,24] For the first time, the paper expounds the generation of a complex network and the extraction of its topological features from the TL signal to unveil the soot-assisted energy tranport in leaves.…”

Acclimatization through thermal diffusivity tuning of coconut oil – A mode mismatched dual-beam thermal lens study

“…The juxtaposing behavior of the ingredients may be due to the well reported behavior of nanofluids with the concentration of the ingredients. There are reports of transforming a base fluid to exhibit heat trap to heat dissipating nature or thermal diffusivity reduction to thermal diffusivity enhancement simply by changing the concentration of the nanoparticle ingredient [ 33 , 34 ]. This behavior of nanofluids might have been the reason for the coconut oil with Plectranthus amboinicus , onion and O. sanctum as ingredients to exhibit enhanced heat dissipation and hence can be regarded as sheeta veerya .…”
