By turning to Raman spectroscopy, a non-destructive tool, a researcher at Indian Institute of Technology (BHU) Varanasi has found an easy way to check if the gold foil used in Thanjavur paintings is genuine or not. Currently, there is no regulatory mechanism in place to check the quality of gold used in Thanjavur paintings despite the … Continue reading Easy way to tell if the foil used in Thanjavur painting is gold or fake

Bhubaneswar: Urban heat island effect studied in a growing city
Urbanisation of Bhubaneswar, a tier-2 city in Odisha, India, has been rapid at 83% in the last 15 years (2000-2014) and this has led to about 89% decrease in dense vegetation and about 2% decrease in water bodies. This has led to about 1.8 degree C warming of the city compared with surrounding non-urban areas … Continue reading Bhubaneswar: Urban heat island effect studied in a growing city
Decreased dust aerosol leads to reduced rainfall over north India
Even as aerosol loading is increasing at a rate of 3% annually, the quantum of dust aerosol over north India during the pre-monsoon period has reduced during the period 2000-2015. Reduced dust aerosol loading during pre-monsoon period might be reducing rainfall during early monsoon over north India. Though the aerosol burden over north India is … Continue reading Decreased dust aerosol leads to reduced rainfall over north India
