“…Figure 6 shows the FTIR results for the nanofibers, displaying various key peaks responding to the vibrational modes of the functional groups present in both membra The vibrational peak at 486 cm⁻ 1 is characteristic of CF2 bending vibrations. The ba observed at 837 cm⁻ 1 and 879 cm⁻ 1 are associated with out-of-plane deformation vibration CH2 groups and CF2 stretching vibrations, while its swinging vibration is shown at 1179 c The vibrational peak at 1274 cm⁻ 1 is assigned to the bending and asymmetric stretch vibrations of the CF2 group. The peak observed at 1399 cm⁻ 1 was related to the wagging vi tion of CH2 or the stretching vibrations of the CF group.…”

“…Desalination technology has emerged as a critical solution to mitigate the rising global demand for freshwater, which is driven by factors such as population growth, industrialization, and climate change [ 1 ]. One of the major obstacles in desalination is the significant degradation of membrane processes along with water flux decline, known as biofouling, which significantly affects the operational costs and sustainability of desalination systems [ 2 ].…”

Fouling and biofouling remain significant challenges in seawater desalination plants. One practical approach to address these issues is to develop anti-biofouling membranes. Therefore, novel hybrid zinc phthalocyanine/polyvinylidene fluoride-co-hexafluoropropylene (Zn(4-PPOx)4Pc/PVDF-HFP) membranes were prepared by electrospinning to evaluate their properties against biofouling. The hybrid nanofiber membrane was characterized by atomic force microscopy (AFM), attenuated total reflectance-Fourier transform infrared (ATR-FTIR) spectroscopy, and contact angle measurements. The theoretical calculations of PVDF-HFP, Zn(4-PPOx)4Pc), and Zn(4-PPOx)4Pc/PVDF-HFP nanofibers were performed using a hybrid functional RB3LYP and the 6-31 G (d,p) basis set, employing Gaussian 09. DFT calculations illustrated that the calculated physical and electronic parameters ensured the feasibility of the interaction of PVDF-HFP with Zn(4-PPOx)4Pc via a halogen–hydrogen bond, resulting in a highly stable and remarkably reactive structure. Moreover, molecular electrostatic potential (MEP) maps were drawn to identify the reactive regions of the Zn(4-PPOx)4Pc and PVDF-HFP/Zn(4-PPOx)4Pc nanofibers. Molecular docking analysis revealed that Zn(4-PPOx)4Pc has highest binding affinity (−8.56 kcal/mol) with protein from S. aureus (1N67) mainly with ten amino acids (ASP405, LYS374, GLU446, ASN406, ALA441, TYR372, LYS371, TYR448, LYS374, and ALA442). These findings highlight the promising potential of Zn(4-PPOx) 4Pc/PVDF-HFP nanocomposite membranes in improving the efficiency of water desalination by reducing biofouling and providing antibacterial properties.

“…Out of this 3%, only a mere 0.5% is accessible to us, and the rest is in the oceans . To meet this freshwater scarcity, seawater desalination has emerged as a reliable method. , However, the desalination process is typically reliant on fossil fuel, leading to significant CO 2 emissions. It is estimated that a total of 76 million tons of CO 2 are emitted by the operational desalination plants worldwide, and this number is likely to increase to 218 million tons by 2040 .…”

Water scarcity has become one of the top risks, along with global warming, primarily caused by increasing energy usage. The problem of desalinating water that is a highly energy intensive process gets intensified due to its complex water-energy nexus. Our key objective is to break this nexus by introducing a hybrid solar-thermal multieffect desalination system. More specifically, to unlock the thermodynamic limitation and acquire the benefits of both the thermal (TVC) and mechanical vapor compressor (MVC), an attempt is made to hybridize them for integration with the multieffect distillation (MED) that consequently enhances the yield of water. Ensuring globally optimal performance of this hybrid MED-TVC-MVC configuration, it is proposed to further integrate with a solar cell with the aim of achieving carbon neutrality at the cost of increased capital investment. Imposing a carbon tax is inevitable, and with adding this, we finally explore the techno-economic feasibility of the sustainable solar MED-TVC-MVC. This novel desalination system secures zero carbon emission with reduced freshwater production cost (FWPC) and enhanced recovery ratio with respect to the real-time MED-TVC plant.
