Powder XRD studies showed that the thermoelectric phase is the major one in all cases, with higher amount of secondary phases in the textured ones due to their incongruent melting. Microstructural characterization revealed a drastic microstructural modification in the textured samples, when compared to the sintered ones, producing much larger and well oriented grains along the growth direction. These characteristics led to lower electrical resistivity in textured samples, reaching the minimum at 650 °C (14.8 mΩ cm) in 0.125Ba-doped samples, which is lower than those typically reported in this system. On the other hand, no significant variation in Seebeck coefficient has been found between the samples. This behaviour is associated to the isovalent doping which does not modify the charge carrier concentration in the material, and the highest values at 650 °C (166 μV/K) are in the order of the reported in the literature. As a consequence, power factor values are mainly driven by the electrical resistivity values, leading to the highest values at 650 °C in 0.125Ba-doped textured samples (0.19 mW/K²m) due to their lowest resistivity. These values are higher than the reported for textured materials and in the order of the best reported for this compound in bulk form.

The properties of CPG and their relation with purification performance were investigated using various characterization techniques and photocatalysis evaluation. As a result, we found that the advanced porous structure of graphene sponge can favor wastewater adsorption and photon utilization efficiency due to the crosslink channels with a higher crosslinking density. Meanwhile, the layered structure of CN_x effectively facilitates the transfer of charge carriers while the PANI exhibits high-capacity visible light adsorption. Consequently, after optimization, CPG8 exhibited better photocatalytic activity with a sulfamethazine degradability of 10 mg/L within 40 min.

Interestingly, this work investigates the augmentation of photon absorption and overall efficiency in low-cost, effective active layers (ALs) via gamma irradiation treatment, thereby raising the number of active absorption sites. For the first time, novel Chitosan@PVA@rGO (CPG) composite sheets were created as AL materials and treated to varied dosages of in-situ gamma irradiation (0, 10, 20, 30, and 40 KGy) to optimize their microstructural and physicochemical characteristics. The processed ALs were subjected to comprehensive tests, which included J–V variable evaluation as well as evaluations of microstructure, porosity, morphology, contact angle, optical characteristics, and electrochemical impedance spectroscopy (EIS). The findings reveal that the composites' surface properties got better gradually as gamma irradiation dosages grew; peak performance was reached at 30 KGy (75.9 % apparent porosity and roughness parameter Ra = 6.22 μm). Extended gamma irradiation resulted in increased DSSC efficiency, which reached 6.85 % after 10 KGy and 7.63 % after 20 KGy. High-energy gamma photons boosted mobility and decreased resistive limits by reducing carrier recombination and facilitating charge carrier movement inside CPG compounds. This increased the longevity and charge transfer efficiency of the solar cell. After 30 KGy alteration, the CPG AL's optimized efficiency of 8.78 % and J_sc of 20.23 mA/cm² indicate a 44.3 % improvement in efficacy over the pristine material. The insertion of oxygen-enriched free radicals into the CPG structure is responsible for the improvement in photovoltaic efficiency because it creates continuous pathways for fast electron transport.
