Summary: This study investigates the use of ammonia as a primary fuel with biodiesel in a dual-fuel mode. The results show that up to 69.4% of the input energy can be provided by ammonia, but increasing the ammonia mass flow rate slightly decreases the brake thermal efficiency. Furthermore, increasing the ammonia load contribution significantly reduces CO2, CO, and HC emissions, but increases NO emissions. Ammonia delays the start of combustion and decreases the combustion duration compared to pure biodiesel operation.

Summary: Oxygenated fuels, such as blends of biodiesel and high-alcohol content, have gained increasing interest as sustainable alternative fuels for diesel engines. This study evaluated the emissions of a diesel engine running on a biodiesel-propanol blend fuel, and found that the blend significantly reduced the levels of PAHs, a health hazard and detrimental to engine components. However, adding too much propanol to biodiesel appeared to result in an increase in PAHs and toxicity.

Summary: The global market for fuel pellets is growing due to coal substitutes, but sustainability and biomass availability are major issues. Spent coffee grounds can be used to produce high heating value fuel pellets, but burning 100% SCG leads to high NO R emissions and low boiler efficiency. Mixing SCG with other biomass improves combustion performance. Further research is needed on the combustion and emissions of defatted spent coffee grounds.

Summary: A series of palm-based liquid crystals were synthesized using palm fatty acids and their smectic A phase was confirmed by microscopy, calorimetry, and scattering techniques. The range of the smectic phase was found to be influenced by the length of the flexible alkyl chains, the presence of polar terminal substituents, and the breath to width ratio of the mesogenic core. Dielectric measurements also showed that the dielectric strength was affected by the length of the flexible alkyl chains. Interestingly, these palm-based liquid crystals exhibited superior mesophase range compared to other structurally related compounds.
