What is the current phosphorus concentration in aerosols across different regions of India?
5 answers
The current phosphorus concentration in aerosols across different regions of India varies based on the study areas. In a Canadian urban area, phosphorus levels in air particulate samples remained relatively stable between 2007 and 2015, with peak levels observed during April-June periods. On the other hand, in Indian regions like the Indo-Gangetic Plains and South India, there has been an increasing trend in Aerosol Optical Depth (AOD) over the years, indicating a rise in aerosol loading. Additionally, studies focusing on coal mine regions in India observed an increasing trend in AOD550 over the years, particularly during winter and post-monsoon seasons, which are dominated by anthropogenic emissions. These findings collectively suggest a complex and region-specific pattern of phosphorus concentration in aerosols across different parts of India.

Why PP have higher tensile strength compare to PLA?
5 answers
PP (Polypropylene) has higher tensile strength compared to PLA (Polylactic Acid) due to the composition and reinforcement effects. PLA, commonly used in FDM printing, exhibits lower tensile strength than PP. PLA's tensile strength can be enhanced by incorporating materials like Copper particles or PBAT blends. On the other hand, PP shows higher tensile strength due to the addition of acrylate rubber, polybutadiene rubber, zinc oxide whiskers, and a compatibilizer, which collectively improve its strength and impact performance. Additionally, when comparing cellulose fiber-reinforced composites, PLA composites show significant reinforcement effects but are more brittle compared to PP composites, which exhibit a ductile stress-strain behavior. Therefore, the unique composition and reinforcement mechanisms in PP contribute to its higher tensile strength compared to PLA.
