The use of photothermal techniques has become of special importance due to their versatile application in the thermal characterization of materials. Therefore, the thermal lens technique in the mismatched dual-beam mode is an alternative, sensitive and non-evasive tool that was used in this research to determine the thermal diffusivity of Moringa oleifera. The dual arrangement of the thermal lens technique is based on the use of an Ar + Xe excitation laser (422 nm) and a He-Ne laser (632 nm) test laser. Moringa solutions were prepared by green synthesis with different concentrations ranging from 1.56 mg•mL −1 , 3.12 mg•mL −1 , 6.25 mg•mL −1 to 12.50 mg•mL −1. Different optical techniques (UV-vis, FTIR, XPS and EDS) were used to characterize the Moringa leaf powders. Results showed that the increase of thermal diffusivity could be related to the presence of functional groups and metallic elements in Moringa elemental composition. In this work, it was found that the thermal diffusivity of Moringa increases with increasing concentration. This study will be useful for application in heat transport and drug release.

“…When a laser beam is allowed to fall on the sample, the atoms or molecules are excited to higher energy levels from where they return to the lower energy levels by liberating excess energy either by radiative or nonradiative transitions. The nonradiative transition results in the generation of heat within the sample, which in turn bring changes in its refractive index with respect to the temperature gradient . Due to the refractive index gradient, the medium acts as a lens‐like optical element, called TL .…”

Nano cellulose is a material of current interest that has attracted considerable attention from researchers due to its interesting properties such as low toxicity, availability, natural abundance, biodegradability, and flexible surface chemistry. Cellulose fiber, usually derived from wood, plant walls or cotton is an eco-friendly thermal insulation material. The cellulose nanofibers (CNFs) described in this work were derived from cotton via sulfuric acid hydrolysis followed by ultrasonication. The formation of CNF and its morphology were analyzed using Fourier transform infrared spectroscopy (FTIR) and transmission electron microscopy (TEM). The thermooptic parameters of the prepared sample, which to the author's knowledge has not been reported so far, were studied by the dual beam mode-matched thermal lens technique. Thermal diffusivity (2.61 × 10 −8 m 2 /s) and thermal conductivity (0.108 W/mK) values of the prepared CNFs clearly point to the application potential of the material.
