Application of response surface methodology on performance and emission characteristics of a diesel engine fueled with diesel, pentanol, and biogas.

The current investigation's objective is to compare various pentanol/biogas/diesel fuel mixes' performance and exhaust parameters in a dual fuel engine. The varied flow rates of gaseous fuel (10, 20, and 30 L per minute) and pentanol fractions (10, 15, and 20%) in conventional diesel at various engine loads (20, 60, and 100%) were studied. Response surface approach was used to assess the researched variables in order to get the best model.

Novel synthetic approach of 2D-metal-organic frameworks (MOF) for wastewater treatment.

In addition to their adjustable functionality, structural tunability, and compositional tunability, metal-organic frameworks (MOFs), often known as MOFs, are a distinct form of crystalline porous material.
