“…But until recently, Ln nanomaterials, typically Nd 3+ :LnF 3 , have been introduced in the organisms as PTT probes, first serving for the temperature feedback , and then for both temperature feedback and heating. In addition, to enhance the energy harvest of the probes, high doping nanomaterials such as NaErF 4 , NdVO 4 , and Nd 3+ enriched α-NaYF 4 nanocrystals were very recently proposed. − Unfortunately, current Ln probes are still facing difficulties for PTT application. For instance, Nd 3+ :LnF 3 has a larger particle size basically >15 nm (Table S1) and relatively low heat generation due to limited doping concentration; NdVO 4 yields extremely weak light, and thus the problem is lack of temperature feedback.…”

Photothermal therapy (PTT) has been widely used for the treatment of various medical conditions due to their noninvasive and cost-effective advantages. However, the light absorption and scattering of the biosystem limit the deep tissue applications of conventional PTT probes. In this paper, we proposed the sub-10 nm NaNdF 4 nanocrystals with both incident and emission wavelengths located at the optical window. Under 800 nm laser excitation, the maximum light-to-heat conversion efficiency of these ultrasmall photothermal agents is evaluated to be 85%. In addition, the conversion efficiency can be further adjusted through varying the doping concentration, changing the probe size, and coating the inert shell. Meanwhile, temperature feedback on the basis of the Nd 3+ luminescence signal validates the precise temperature manipulating inside the biological tissue, evidencing the feasibility of the proposed probes for PTT treatment. Beneficial from the efficient photothermal conversion and low energy loss of excitation/ emission photons in organic tissue, the effective treatment depth of the nanoprobes goes to 6 mm with the actual laser power density only ∼0.2 W/cm 2 . Finally, based on the rapid heating response of the formed nanoprobes, fast ablation treatment of a 1.5 cm pork tissue is achieved using pulsed laser.

“…The photothermal effects of the laser irradiation on the LaOF:Yb 3+ , Er 3+ UCNPs were investigated by determining their heat efficiency under the 980 nm laser with a power density of 6.91 W/cm 2 . The steps employed for the determination of the photothermal conversion efficiency (η) is described in the Supporting Information. − The light-to-heat conversion efficiency was found to be 11.92% for the LaOF:Yb 3+ , Er 3+ UCNPs. From the perspective of luminescence thermometry, this value of photothermal conversion efficiency is acceptable and would not produce any significant alteration in the thermal readouts.…”

Luminescence nanothermometers based on LaOF:Yb3+, Er3+ upconversion nanoparticles (UCNPs) were investigated in this study. The fluorescence intensity ratio (FIR) of the UCNPs was recorded in the visible (red) and near-infrared (NIR) regions at different temperatures. The impact of laser heating on the UCNPs was prevented by identifying the optimal operating conditions of the laser that could be used to record the FIRs without compromising the integrity of the UCNPs. The behavior of the UCNPs against the laser exposure time and power was analyzed to recognize the critical point of the laser power, below which laser heating of the UCNPs was negligible. This approach can be perceived as a benchmark for testing luminescent materials using nanothermometry.

“…Moreover, higher the values of the thread setting density, linear density, weight per square meter (GSM), and tensile properties better will be the performance and quality of textile products [38,39]. The recycled textile and composites materials have reasonable applications in optical sensing, automobiles and medical industries [40,41]. Based on literature and experimental results, it can be concluded that relative sliding COF value between textile waste and metallic components during shredding, cutting, and recycling should be greater than 0.25 due to damage, rough, and the distorted surface of textile fabrics.…”

The circular economy is still a hypothetical field in Europe. Different shredding and manufacturing machinery parts in textile industries are presumed to enhance product quality and performance. The quality and performance of recycled textile products play a vital role in the development of textile recycling technologies. The quality is principally associated with the mechanical and tribological properties of machinery parts. In this article, TiCN Coating is used to determine the coefficient of friction of post-consumer cotton fabric. The scanning electron microscope, optical and mechanical profilometer, and tribometer were used for surface and tribological evaluations. The TiCN coating was found smooth and homogeneous. The average coating surface roughness parameters Rmax, Rz, Rp were 0.24 µm, 0.21 µm, and 0.20 µm, respectively. The dynamic coefficient of friction values was found 0.38 to 0.30 in the warp and 0.33 to 0.28 in weft directions. The increase in sliding distance is used for industrial applications and evaluations. The increase in distance deformed and fractured cotton fabric surface. The coefficient of friction and deformation becomes constant after 40 m of sliding distance. Based on coefficient of friction values, permanent deformation, fracture, and morphologies evaluations TiCN coatings could be used operationally for surface modification of textile machinery parts. The surface modification of textile machinery parts with TiCN coating can enhance the quality and performance of textile products.
