“…In this connection, we believe that the TLS approach developed in this work could be complemented with fast PTS techniques mentioned above: first, with impulsive stimulated scattering, which provides a very reliable information of thermal diffusivity. − Such a combined method would provide the information on the dispersion medium alone with a good precision, which will be the basis of thermal-lens calculations on the dispersed particles. It would be also interesting to combine thermal lensing with the techniques heat profiling of three-dimensionally optically trapped metal nanoparticles .…”

“…They may be classified relative to the time scale of the underlying thermal probing process. The first group is based on fast (microsecond or shorter timescales) photothermal phenomena like transient-grating methods, − optical heterodyne detection, or impulsive stimulated scattering (ISS) − and other transient techniques . These fast techniques are used for investigating dynamics of charge transfer, , thermoelastic properties, or ultrafast heat transfer inside nanoparticles. − …”

Approach to the Assessment of Size-Dependent Thermal Properties of Disperse Solutions: Time-Resolved Photothermal Lensing of Aqueous Pristine Fullerenes C₆₀ and C₇₀

An approach is proposed for assessment of the thermal properties of aqueous pristine fullerene C60 and C70 dispersions (AFDs) at the level of 10–7–10–5 mol L–1 by photothermal (thermal-lens) spectroscopy for their application in medicine and technology. Along with relevant size-characterization techniquesdifferential scanning calorimetry (DSC) with the Gibbs–Kelvin equation and dynamic light scattering (DLS) techniquesthis approach provides an estimation of the size-dependent thermal properties of disperse solutionsthermal diffusivity, thermal effusivity [thermal inertia], and thermal conductivity. The values for AFDs under the conditions of the attained thermal equilibrium show good precision, and the cluster size estimations agree with the reference methods. The reconstruction of the thermal-lens characteristic time over the course of the blooming of the thermal-lens effect reveals a short increase in the apparent thermal diffusivity. This is accounted for by nonequilibrium heat transfer within fullerene clusters upon initial laser heating, which is supported by the independent estimations from widespread methods like high-resolution transmission electron microscopy, DLS, and DSC. Thermophysical parameters of the disperse phase estimated from transient thermal lensing are as follows: thermal diffusivity, 1.6–2.0 × 10–7 m2 s–1 depending on fullerene concentration and up to 3.5 × 10–7 m2 s–1, more than 2-fold higher than for water; thermal effusivity, 6.7 × 102 J m–2 K–1 s–1/2, three times lower than for water.

“…PTS is actively involved in the nondestructive characterization of dispersed systems, − although there are almost no nanodiamond studies . Thermal lensing as a relatively simple and reliable method is among the most used photothermal modalities toward this aim. − Still, in carbon nanomaterials, many factors may affect the thermal parameters and, thus, the results of measurements. , Thus, it is relevant to develop a methodology for photothermal-lens measurements of heat-conducting properties of nanodiamond-based dispersed solutions and within the framework of their wider physicochemical diagnostics.…”

Photothermal and Heat-Transfer Properties of Aqueous Detonation Nanodiamonds by Photothermal Microscopy and Transient Spectroscopy

et al. 2021

Characteristic size and heat-transfer parameters of aqueous detonation-nanodiamond dispersions of various brands as carbon-based nanomaterials for nanofluidic tasks were assessed by confocal photothermal microscopy and transient (time-resolved) photothermal-lens modalities. It was shown that only the part of the transient thermal-lens heating curve of the dispersed sample with light-absorbing particles when the photothermally induced thermal field becomes homogeneous should be used to evaluate the bulk thermal diffusivity. For nanodiamond concentrations of 1−4 mg/ mL, a 1−5% increase in thermal diffusivity and thermal conductivity compared with water is observed. A slowdown in the dissipation of the thermal lens effect due to prolonged heat accumulation by nanodiamonds is shown, which is confirmed by significant photothermal signals from nanodiamond clusters according to confocal photothermal microscopy. The size estimation of separate nanodiamond clusters in solution by nonlinear far-field confocal photothermal microscopy is shown; for the selected nanodiamond brands, photothermal microscopy reveals local signals (200−1000 nm) from nanodiamonds that can be assigned to aggregates of ca. 40−70 nm correlated with calculations from the Gibbs−Kelvin equation by differential scanning calorimetry. The discrimination of nonaggregated and aggregated nanodiamonds by photothermal microscopy is demonstrated.

Vegetable oils have been rising its use in several areas ranging from lubricant additives up to cosmetic industry, therefore, the price of this commodities is rising and the research for new ways to ensure the purity of the oil. By another hand, the photopyroelectric techniques, which are based on the interaction of modulated light, sample, and sensor, have proven to be a useful tool to analyze thermal properties of several kinds of liquids, in several applications. In this work, an introduction to photothermal techniques is given and based on its capabilities the reasons why this kind of techniques can be used for the analysis of samples pureness.
