Mozambique is an agricultural country. However, it faces numerous challenges to feed the population and reduce poverty. Recently, the situation is being worsened by high environmental, social vulnerability and extreme ...

A Zintl-phased K3Ag3As2 ternary compound previously not studied using ab initio techniques was analysed for its structural, electronic, mechanical, elastic, and optical properties using LDA-PZ, GGA-EV, GGA-PBE, GGA-PBESol, ...

Tandem solar cells (TSCs) have gained notoriety by the use of various absorber layers with different bandgaps. The photovoltaic characteristics of Cs1-xRbxSnI3 perovskite – silicon TSCs were determined through simulation ...

Open sun drying is the conventional approach used in the majority of developing countries to dry agricultural products. However, this method exposes agricultural products to a number of hazards, including microbial ...

In the present study, a solar-assisted heat pump dryer (SAHPD) has been designed, fabricated, and tested its performance on drying tobacco leaves. The hot air generated from the solar collector and condenser unit of the ...

Efficient materials with good optoelectronic properties are required for the good performance of photovoltaic devices. In this work, we present findings of a theoretical investigation of the structural, electronic, elastic, ...

This study investigates the utility of using remote sensing and geographic information system techniques to accurately infer the presence of radioactive minerals in a typical high background radiation area (HBRA) by analyzing ...

There is a great need for improved monitoring of the numerous lakes in East Africa. These lakes are important resources that are facing serious threats from climate change and human development and exploitation. A new ...

Fruits and vegetables are agricultural products that require preservation to enhance and protect shelf life, encapsulate natural flavour, and retain nutritional content. Globally, agricultural products are preserved by a ...

First-principles calculations of the structural, electronic, elastic, mechanical, and optical properties of the K2NiP2 ternary compound using density functional theory as implemented in the quantum espresso package have ...
