Digitization has completely changed the landscape of supply chain management, which enables businesses to streamline their processes and attain higher levels of profitability and sustainability. This study investigates the relationships between digitalization and supply chain elements, particularly integration, communication, operation, and distribution, and their effects on corporate profitability and sustainability. The research is based on an empirical investigation conducted through a questionnaire survey of agri-food industries in Pakistan. PLS-SEM was used for the analysis of data. The results show a positive relationship between digitalization and supply chain integration, processes, operation, and distribution. Moreover, a positive and significant relationship exists between digitalized supply chain integration, processes, operation, and distribution with business profitability and sustainability. The research concludes that the synergistic effect of digital advancements leads to increased business profitability and sustainability. Business organizations may put themselves at the forefront of supply chain excellence by adopting digitalization, benefiting from effective integration, communication, operations, and distribution with increased profitability and sustainability. The findings have a lot of practical and theoretical implications for the excellence of supply chain management and help attain several sustainable development goals, e.g., SDG-8, SDG-9, SDG-11, and SDG-12.

The design and development of a photovoltaic thermal (PVT) collector were developed in this study, and electrical and electrical thermal efficiency were assessed. To improve system performance, two types of coolants were employed, liquid and liquid-based MnO nanofluid. Flow rates ranging from 1 to 4 liters per minute (LPM) for the interval of 1.0 LPM were employed, together with a 0.1% concentration of manganese oxide (MnO) nanofluid. Various parametric investigations, including electrical power generation, glazing surface temperature, electrical efficiency, and electrical thermal efficiency, were carried out on testing days, which were clear and sunny. Outdoor studies for the aforementioned nanofluids and liquids were carried out at volume flow rates ranging from 1 to 4 LPM, which can be compared for reference to a freestanding PV system. The research of two efficiency levels, electrical and electrical thermal, revealed that MnO water nanofluid provides better photovoltaic energy conversion than water nanofluid and stand-alone PV systems. In this study, three different domains were examined: stand-alone PV, liquid-based PVT collector, and liquid-based MnO nanofluids. The stand-alone PV system achieved a lower performance, the liquid-based MnO performed better, and the liquid-based PVT achieved an intermediate level.
