MQL Machining with nano fluid: a review [PDF]

Manufacturing Review, 2021
In any metal cutting machining operation, the cutting fluid plays important role by cooling the cutting tool and the surface of the work piece, also chips are removed from heat affected zone. However, misuse of the cutting fluid and wrong methods of its disposal can affect human health and the environment badly.

Enantioselective Determination of Amphetamine-Type Stimulants in Environmental Waters Using SPE and CE-MS/MS. [PDF]

Electrophoresis
ABSTRACT The growing concern over drug abuse, particularly involving amphetamine‐type substances (ATS), has led to their monitoring in environmental waters. These chiral compounds, commonly found in river water and wastewater treatment plant (WWTP) effluents, require analytical methods capable of enantiomeric discrimination, as their enantiomers can ...
