In the current study, an efficient composite of CuS/CoS petal-like nanoarchitectures was synthesized by the two-step facile hydrothermal route as a binder-free electrode for supercapattery applications. The phase, structural and morphological analyses revealed the nanocomposites of CuS/CoS facilitate the abundant intermittent spaces and redox-active sites responsible for their enhanced energy storage behaviour than CuS and CoS. This was further confirmed by the electrochemical measurements yielding the specific capacity of 138.75 mA h g−1 at a current density of 1 A g−1 with an excellent capacity retention of 87.56% and cycling stability of 94.28% over 4000 cycles. The power-law elucidated in the current work demonstrated the nanohybrid CuS/CoS is the best suit for supercapattery applications.

Water is the most desirable and sparse resource in Gulf cooperation council (GCC) region. Utilization of point-of-use (POU) water treatment devices has been gaining huge market recently due to increase in knowledge of urban population on health related issues over contaminants in decentralized water distribution networks. However, there is no foolproof way of knowing whether the treated water is free of contaminants harmful for drinking and hence reliance on certified bottled water has increased worldwide. The bottling process right from treatment to delivery is highly unsustainable due to huge energy demand along the supply chain. As a step towards sustainability, we investigated various ways of coupling of membrane distillation (MD) process with solar domestic heaters for co-production of domestic heat and pure water. Performance dynamics of various integration techniques have been evaluated and appropriate configuration has been identified for real scale application. A solar combi MD (SCMD) system is experimentally tested for single household application for production 20 L/day of pure water and 250 L/day of hot water simultaneously without any auxiliary heating device. The efficiency of co-production system is compared with individual operation of solar heaters and solar membrane distillation.
