The ISM technique was used for the result. It was found that the \"Lubricity\" and \"Iodine content\" were important factors which plays a good role on affecting the animal fat biodiesel. Also, the study showed that animal fats biodiesel has a good fuel characteristic. These results are much beneficial for researchers and managers who are involved in the biodiesel manufacturing industry. Comprehending the impact of \"Lubricity\" and \"Iodine content\" on fuel characteristics enables researchers to focus their endeavors on augmenting these traits.

Online gas product quantification was conducted using micro-gas chromatography. Analysis of the Cu-based GDL’s surface morphology and crystallinity before and after CO₂RR revealed significant structural changes, transitioning from microscale particles to a flowery-shaped configuration and shifting from pure copper (Cu) to a mixture of copper (Cu) and cupric oxide (Cu₂O).

This research aims to assess the carbon footprint of dairy production in the Antioquia region and propose actionable, cost-effective mitigation strategies. In accordance with the IPCC guidelines, a Tier 2 approach was employed for the majority of emission factors. For enteric methane emissions, a Tier 3 approach has been employed, based on in situ measurements, to establish a baseline of GHG emissions and propose mitigation measures. The most cost-effective measure is evaluated through a MACC analysis to determine the optimal approach for reducing these emissions. Results indicate an average annual emission of 2.6 tCO₂e per dairy cow, with methane contributing 89 % of the carbon footprint, . Optimal pasture management emerged as the most cost-effective mitigation strategy, achieving a potential reduction of 880.8 tCO₂e in 10 years of proyection, at a negative marginal cost of -$99.70 per tCO₂e.

Correspondingly, this study investigates the electrochemical behaviour of aluminium in brackish peat water with varied seawater percentages that ranged from 0% to 100%. When seawater percentage increases from 0% to 50%, Tafel extrapolation reported a pronounced negative shift in the corrosion potential from -337.542 mV to -921.292 mV along with a sharp increase in corrosion current density from 4.581 µA/cm² to 34.290 µA/cm².
