Abstract In the last two decades, use of duplex stainless steel (DSS) has increased significantly in structural applications due to their low maintenance costs, excellent corrosion resistance highly corrosive environments, and high mechanical strength. The production thicker plates by hot rolling leads larger grains sizes material. Besides this, different plate thicknesses have cooling rates af...

This study focuses on the preparation of fine-grained WC/Co composite powder using rolling ball milling and spray drying techniques. The cemented carbide composition achieved through low-pressure sintering technology was WC-10Co-0.5Cr3C2-1TaC-0.5Ru (wt.%). To effect temperature microstructure mechanical properties WC-10 wt.% carbide, phase constituents material were analyzed X-ray diffractometr...

With more than 156,000 described species, eukaryotic algae (both macro- and micro-algae) are a rich source of biological diversity, however their chemical diversity remains largely unexplored. Specialised metabolites with promising activities have been widely reported for seaweeds, recently extracts from microalgae exhibited activity in anticancer, antimicrobial, antioxidant screens. However, w...

The solar irradiation at the gulf Arabia is considered one of highest in world. However, this region classified as a desert with high dust accumulation. Thus, objective study to analyze effect soiling and photovoltaic (PV) tilt angle on performance 2.0 MWp car park PV plant Oman. Experimental measurements were taken model was developed for simulation. power generation by cleaned system measured...
