Scientists ID New Catalyst for Cleanup of Nitrites

Chemical engineers at Rice University have found a new catalyst that can rapidly break down nitrites, a common and harmful contaminant in drinking water that often results from overuse of agricultural fertilizers.

Nitrites and their more abundant cousins, nitrates, are inorganic compounds that are often found in both groundwater and surface water. The compounds are a health hazard, and the Environmental Protection Agency places strict limits on the amount of nitrates and nitrites in drinking water. While it’s possible to remove nitrates and nitrites from water with filters and resins, the process can be prohibitively expensive.

Do not get over excited over happiness and do not get over depressed over sorrow.

Do not get over bonded with anyone and anybody because it can lead to problems and sorrow.

Never think that my duty is the topmost or lowermost. Every duty is respectful. The responsibility undertaken or given as per the position is the noblest duty.

Elevate yourselves, family, society and nation and never denigrate yourselves, family, society and nation.

We are our own closest relatives and if not properly utilised we will become our closest enemies.

There are possibilities of success and failure in any endeavour. One cannot assure success always.

Death is inevitable for everyone in this world. In any endeavour at the maximum an individual may die.

People may say good and also they may say bad. Approach them with stabilised mind.

Take anything after scientifically, logically and rationally analysing them.

Perform your duty, responsibility and accept the privileges eligible for you.

First change ourselves and then try to change others.

We are all instruments /tools in the hands of the nature for performing the duty. So do not think that I am doing the duty. Think that I am an instrument to do the duty.

Results of action may not be sweet always. Accept what ever may be the result.

Follow the path of great scholars who guided the world. Listen their messages.

Results and rewards will come and go but stick to your duty with devotion, dedication and sincerity.
