Experimental multi-level calibration of a silicon mini solar cell for low-cost solar irradiance measurement

Abstract Accurate assessment of photovoltaic potential is essential for optimizing system integration at specific sites, requiring precise measurement of ground-level solar irradiance. However, commercially available irradiance sensors are often costly, limited in configurability...

A multi-index screening framework for selecting bacterial and fungal isolates for heavy-metal detoxification

Heavy-metal contamination of wastewater represents a major environmental challenge because of its persistence, toxicity, and bioaccumulation potential in aquatic ecosystems. Microbial bioremediation has emerged as a sustainable and cost-effective approach for detoxifying metal-co...

Numerical investigation of mixed convection heat transfer of water-Fe3O4 nanofluid in a corrugated channel with moving walls

Abstract Increasing heat transfer in heat exchangers and ducts filled with various operating fluids for heat transfer is one of the main concerns of researchers and engineers in the energy conversion in the field of thermal engineering. Two examples of methods for increasing heat...

Biochemical effects of occupational diagnostic ionizing radiation exposure on medical radiographers: AI-assisted exploratory radiation biological effect score (RBES)

Medical radiographers are chronically exposed to low-dose ionizing radiation during diagnostic imaging procedures, raising concerns about the cumulative biological effects of prolonged occupational exposure despite adherence to international radiation protection standards. This c...

The impact of global influence on peace and stability conditions in G20 countries

Peace, cooperation, and stable relations among nations are essential for maintaining global stability. This study applies Power Transition Theory (PTT) to examine how global factors influence peace and stability conditions among G20 countries. It uses 16 years of data (2008–2023)...

Conducting Polymers: Materials, Mechanisms, and Applications – a Review

The 2000 Nobel Prize in Chemistry was awarded to Alan J. Heeger, Alan G. MacDiarmid, and Hideki Shirakawa for the discovery and development of conductive polymers, particularly polyacetylene. Since then, research on conducting polymers has progressed rapidly, with sustained focus...
