the research in new organic π-conjugated molecules with specific properties has become one of the most interesting topics in fields of materials chemistry. these materials are promising for optoelectronic device technology such as solar cells. on the other hand, the use of low band gap materials is a viable method for better harvesting of the solar spectrum and increasing its efficiency. the co...

The study evaluated the physical and chemical characteristics of vermicompost mixtures to optimize nutrient extraction. Three compost (chicken plus horse (CH+H), chicken cattle (CH+C), (C+H)) were selected for quality evaluation at three extraction times: 24, 48, 72 h. results showed differences (p < 0.05) in concentration teas different mixtures. interaction between treatments time a signif...
