1. Lok Sabha passes supplementary demand for grants
The Lok Sabha passed the supplementary demand for grants on 18.3.2021.
Prelims GS – Polity
Article 114 and Article 115:
- Article 114 deals with the Appropriation bills which provide for the appropriation out of the Consolidated Fund of India.
- Article 115 deals with the Supplementary, additional, or excess grants.
Article 115: Supplementary, additional, or excess grants.—
(Note: The following points are directly taken from the Constitution of India book.)
(1) The President shall—
(a) if the amount authorized by any law made in accordance with the provisions of article 114 to be expended for a particular service for the current financial year is found to be insufficient for the purposes of that year or when a need has arisen during the current financial year for supplementary or additional expenditure upon some new service not contemplated in the annual financial statement for that year, or
(b) if any money has been spent on any service during a financial year in excess of the amount granted for that service and for that year,
cause to be laid before both the Houses of Parliament another statement showing the estimated amount of that expenditure or cause to be presented to the House of the People demand such excess, as the case may be.
(2)The provisions of articles 112, 113, and 114 shall have effect in relation to any such statement and expenditure or demand and also to any law to be made authorizing the appropriation of money out of the Consolidated Fund of India to meet such expenditure or the grant in respect of such demand as they have effect in relation to the annual financial statement and the expenditure mentioned therein or to a demand for a grant and the law to be made for the authorization of appropriation of money out of the Consolidated Fund of India to meet such expenditure or grant.

2. Artificial Photosynthesis
Scientists have found a method called Artificial Photosynthesis to mimic nature’s own process of reducing carbon dioxide in the atmosphere, namely photosynthesis, to capture excess carbon dioxide in the atmosphere.
Prelims GS – Science & Technology
- Artificial photosynthesis (AP) harnesses solar energy and converts the captured carbon dioxide to carbon monoxide (CO), which can be used as a fuel for internal combustion engines.
- In artificial photosynthesis (AP), scientists are essentially conducting the same fundamental process in natural photosynthesis but with simpler nanostructures.
- The scientists have immobilized a photosensitizer, which is a chemical called ruthenium bipyridyl complex ([Ru(bpy)2Cl2]) and a catalytic part which is another chemical called rhenium carbonyl complex ([Re(CO)5Cl]), inside the nano space of metal-organic framework for artificial photosynthesis.
- Both these molecular entities stay in close proximity in the confined nano-space of a porous metal-organic framework system resulting in excellent CO2 uptake capability at room temperature.
- This synthetic strategy empowers efficient solar light-driven photocatalysis.
