The development of human society has inevitably caused damage to the Earth's environment, particularly impacting the crucial water cycle. The urgent need to address the scarcity of freshwater resources faced by humanity is evident. Drawing inspiration from the phenomenon of plant transpiration, this study presents a cutting-edge approach that leverages abandoned cotton textiles to fabricate a novel Janus evaporator with distinctive micro−nanoarchitecture, aligning with eco-friendly principles, termed the MoS 2 @CNTs/CNC Janus evaporator (MCC evaporator). Crafted from its own underlying micronano multilayer structure with superhydrophilicity and the upper layer of photothermal material with superhydrophobicity, the Janus architecture of the evaporator showcases remarkable performance. Under solar irradiation, the evaporation rate of the MCC evaporator can reach 3.16 kg m −2 h −1 , even at a salinity of 20 wt %, while demonstrating continuous operation for 8 h. Moreover, the application of the MCC evaporator in a dual-driven evaporation system powered by solar energy and low-grade waste heat (LGWH) holds promising potential. The calculated performance from the mathematical model of the MCC evaporator closely aligns with the observed results, with a mean square error of less than 10 −1 , highlighting the accuracy of the prediction model. This predictive model holds significant potential for optimizing and forecasting the performance of evaporators.

“…Note that the composite fibers at high MoS 2 content (20 and 30 wt%) do not have improved photothermal ability, which is highly possible due to insufficient exfoliation and unwanted aggregation. [26] MoS 2 holosphere coated cotton textile, [12] MoS 2 /rubber sponge, [17] Mxene/MoS 2 nanocomposite-loaded electrospun nanofiber membrane [15] and MoS 2 modified mask fabrics; [8] The temperature change (the highest temperature output minus the original room temperature) is used as an evaluation criterion to compare the present materials to other MoS 2based macroscopic materials (Figure 4b). [8,12,15,17,26] Promisingly, CNF/MoS 2 -10 composite fibers are in the same league as other works.…”

“…[24] Furthermore, dispersion of such nanoparticles is also a typical issue as unwanted aggregation tends to deteriorate their overall properties, which begs the reasonable orchestration of supportive materials and incorporation methods. [25,26] Regarding thermal regulating performance, phase change materials (PCM) can be integrated during or after fiber fabrication to provide a smart thermal energy storage and release capacity. Many strategies have been developed to fabricate PCMloaded composite fibers such as post-impregnation, [27,28] surface grafting/coating, [29] and in situ blending, [30][31][32] yet facing the inevitable problems of abrasion/leakage of PCM.…”

Flexible fibers and textiles featuring photothermal conversion and storage capacities are ideal platforms for solar‐energy utilization and wearable thermal management. Other than using fossil‐fuel‐based synthetic fibers, re‐designing natural fibers with nanotechnology is a sustainable but challenging option. Herein, advanced core–shell structure fibers based on plant‐based nanocelluloses are obtained using a facile co‐axial wet‐spinning process, which has superior photothermal and thermal‐regulating performances. Besides serving as the continuous matrix, nanocelluloses also have two other important roles: dispersing agent when exfoliating molybdenum disulfide (MoS2), and stabilizer for phase change materials (PCM) in the form of Pickering emulsion. Consequently, the shell layer contains well‐oriented nanocelluloses and MoS2, and the core layer contains a high content of PCM in a leak‐proof encapsulated manner. Such a hierarchical cellulosic supportive structure leads to high mechanical strength (139 MPa), favorable flexibility, and large latent heat (92.0 J g−1), surpassing most previous studies. Furthermore, the corresponding woven cloth demonstrates satisfactory thermal‐regulating performance, high solar‐thermal conversion and storage efficiency (78.4–84.3%), and excellent long‐term performance. In all, this work paves a new way to build advanced structures by assembling nanoparticles and polymers for functional composite fibers in advanced solar‐energy‐related applications.

“…Several biomedical applications of aerogel structures have already been proposed, including drug delivery, biosensing, implementable devices, regenerative medicine, tissue engineering, and diagnostic tools [ 1 , 2 , 8 , 22 , 23 , 24 ]. Aerogels have also been proposed for promising therapeutic strategies such as photothermal therapy (PTT) [ 25 , 26 , 27 ]. PTT appeared as an increasingly explored therapeutic option for superficial localized tumors relying on the induction of local hyperthermia of tumor cells upon irradiation with light beams [ 28 , 29 ].…”

“…However, the value of PTT depends greatly on the ability of radiation to penetrate to a certain depth in the tissues and on the ability to generate enough heat able to damage tumor cells. One option to surpass those limitations might include using, in the same system, near-infrared (NIR) radiation and photothermal enhancers such as gold nanoparticles [ 30 , 31 , 32 , 33 ] or hybrid aerogels [ 25 , 26 , 27 ]. NIR radiation represents an advantageous practice because it is less absorbed and scattered by the tissues [ 29 , 34 ], leading to enhanced penetration depth.…”

Aerogels are materials with unique properties, among which are low density and thermal conductivity. They are also known for their exquisite biocompatibility and biodegradability. All these features make them attractive for biomedical applications, such as their potential use in photothermal therapy (PTT). This technique is, yet, still associated with undesirable effects on surrounding tissues which emphasizes the need to minimize the exposure of healthy regions. One way to do so relies on the use of materials able to block the radiation and the heat generated. Aerogels might be potentially useful for this purpose by acting as insulators. Silica- and pectin-based aerogels are reported as the best inorganic and organic thermal insulators, respectively; thus, the aim of this work relies on assessing the possibility of using these materials as light and thermal insulators and delimiters for PTT. Silica- and pectin-based aerogels were prepared and fully characterized. The thermal protection efficacy of the aerogels when irradiated with a near-infrared laser was assessed using phantoms and ex vivo grafts. Lastly, safety was assessed in human volunteers. Both types presented good textural properties and safe profiles. Moreover, thermal activation unveils the better performance of silica-based aerogels, confirming the potential of this material for PTT.
