*🛡️Smog-Eating Technology*

♟️A photocatalytic technology based primarily on Titanium Dioxide (TiO₂).
♟️Works through coatings applied on roads, pavements, buildings, etc. to neutralize air pollutants.

*💎How it Works?*
♟️TiO₂ acts as a photocatalyst when exposed to sunlight/UV light.
♟️Converts harmful gases like Nitrogen Dioxide (NO₂) & VOCs → into nitrates, CO₂ & water.
♟️Creates a “self-cleaning” effect, breaking down pollutants on contact.

*💎Benefits*
♟️Reduces harmful pollutants (NO₂, hydrocarbons).
♟️Improves public health by lowering toxic air exposure.
♟️Low-maintenance, works passively under sunlight.
♟️Can be integrated with existing urban infrastructure without major disruption.

*💎Challenges*
♟️Needs scientific validation under Indian/local conditions.
♟️Cost-effectiveness of large-scale application still debated.
♟️Concerns about long-term durability of coatings & safe disposal of residues.

*🛡️Permanent Settlement*

♟️Zamindari System was introduced by Cornwallis in 1793 through the Permanent Settlement Act.

♟️It was introduced in the provinces of Bengal, Bihar, Orissa and Varanasi.
Also known as Permanent Settlement System.

♟️Zamindars were recognized as the owner of the lands. Zamindars were given the rights to collect the rent from the peasants.

♟️While the zamindars became the owners of the land, the actual farmers became tenants.

♟️The tax was to be paid even at the time of poor yield.
The tax was to be paid in cash. Before introducing this system, the tax could be paid in kind.

♟️The realized amount would be divided into 11 parts. 1/11 of the share belongs to Zamindars and 10/11 of the share belongs to East India Company.
