Environmental challenges and decreasing fossil reserves due to increased utilization of fossil fuels have propagated the importance of alternative energy sources. Increased biodiesel production promoted excess waste crude glycerol leading to environmental issues, thereby inhibiting the sustainability of the process. This review paper discusses the different types of feedstocks utilized to produce glycerol-free biodiesel by reacting with methyl acetate via interesterification. Methyl acetate is used as an advantageous alternative to methanol in biodiesel production to overcome the environmental challenge associated with excess waste glycerol. The by-product, triacetin from the interesterification reaction, has shown excellent qualities as a fuel additive, thereby making the process cleaner and more sustainable as a result of not separating the triacetin from biodiesel. The resulting product referred to as biodiesel fuel (BDF) has been found to exhibit useful properties and applications as fatty acid methyl esters (FAME). The promising environmental and sustainability merits of the process far outweigh the slow interesterification kinetics demerits of the process, which can be overcome by suitable processing conditions. The prospects associated with biodiesel production by interesterification are also pointed out.

The chemical properties of oil from arils of both ripe and unripe ackee (Blighia sapida) were evaluated with a view to investigating the variations in their domestic and industrial applications. The chemical analyses of ripe and unripe aril oils respectively in different locations showed the percentage yield of oil from 54.91±2.75 to 78.25±3.91; 37.78±1.51 to 54.61 ± 2.18, iodine values of 90.0 ± 2.70 to 94.5 ± 2.84; 119.71 ± 5.99 to 131.71 ± 6.39 mg/g oil, saponification values of 190.68 ± 5.72 to 201.73 ± 6.05; 176.17 ± 7.05 to 198.15 ± 7.9 mg KOH/g. Both ripe and unripe ackee arils have peroxide value less than 10mEq/kg and acid value less than 4.0mgKOH/g. The variations between ripe and unripe ackee arils oil may prove useful in their application as cooking oils and industrial raw materials.

The continuous havoc wrecked by tuberculosis among humans worldwide remains colossal. In this work, twenty-one (21) 2-(quinoline-4-yloxy)acetamide analogues were observed against Mycobacterium tuberculosis catalase-peroxidase (This enzyme shields bacteria from poisonous drug-like molecules) (PDB ID: 1sj2 ) using density functional theory method, QSAR study using material studio software and docking method via PyMol, AutoDock Tool, AutoDock Vina and Discovery studio 2017 as well as ADMET study via admetSAR2. Twelve descriptors were obtained from the optimized compounds which were used to develop valid QSAR model. More so, the binding affinity between 2-(quinoline-4-yloxy)acetamide analogues and Mycobacterium tuberculosis catalase-peroxidase (PDB ID: 1sj2 ) via docking method were reported. ADMET properties of some selected compounds were also examined.
