The Critical Role of Economies of Scale: A Techno‐Economic Assessment of Small‐ Versus Large‐Scale Biogas Upgrading in Rural Tanzania

open access: yesEnergy Science &Engineering, EarlyView.
Small‐scale biogas upgrading can improve methane quality but remains financially unattractive to individual rural households. Community‐scale implementation substantially lowers energy costs, demonstrating that economies of scale are critical to making purified biogas a viable clean‐cooking option in Tanzania.

Multi‐Objective RSM Optimization of Emission and Performance Characteristics in a Diesel Engine Fueled With BaTiO3 Nano‐Enhanced Jojoba Biodiesel

open access: yesEnergy Science &Engineering, EarlyView.
This study uses response surface methodology to optimize Jojoba biodiesel blended with BaTiO3 nanoparticles in a single‐cylinder diesel engine. Results show that ~48.95–51.31 ppm of BaTiO3 achieves balanced performance and emission, decreasing CO and NOx while increasing torque and brake thermal efficiency.

An Experimental Study of Thermal Energy Storage With Phase‐Change Material in a Rectangular Box Filled With Aluminum Foam

open access: yesEnergy Science &Engineering, EarlyView.
We experimentally evaluate a rectangular latent‐heat thermal energy storage box filled with paraffin RT57. Embedding 1–3 aluminum‐foam pieces (ε ≈ 0.89 and 10 PPI) increases effective thermal conductivity, making the temperature field more uniform and accelerating phase change.

Air pollution exposure during training impairs performance in Thoroughbred racehorses

open access: yesEquine Veterinary Journal, EarlyView.
Abstract Background Ambient air pollution contributes substantially to human morbidity and mortality, and athletes are recognised as a particularly vulnerable group. However, little is known about the impact of air pollution on equine athletes. Objectives To explore the relationship between air pollution exposure during the pre‐competition training ...
