Summary: In tropical conditions, the temperature exceeding the recommended range in greenhouse is a major concern. This study evaluated the thermal performance of an Earth Air Tunnel Heat Exchanger (EATHE) assisted single span saw-tooth greenhouse using both a developed code and a commercial computer program (ANSYS-Fluent). The effectiveness of coupling EATHE to control the greenhouse temperature was assessed under different scenarios of side vent opening. Air movement caused by wind and stack effect was found to be a significant factor affecting the temperature uniformity within the greenhouse. The best thermal performance for optimum plant growth was achieved when both side vents of the greenhouse were connected to EATHE.

Summary: This study suggests that using production water samples may not be suitable for studying reservoir souring, as they may not accurately reflect the sulfate reducing bacteria responsible for souring in the reservoir. The results indicate that a more accurate prediction of reservoir souring requires understanding the behavior of sulfate reducing bacteria in injection water and formation brine.

Summary: This paper presents an ex-post analysis on the impact of electricity subsidy reform in Iran from 1984 to 2017. The analysis shows that subsidy reform could have reduced electricity consumption by 22% and increased the share of renewable energy in power generation from 5% to 15%. It also reveals that the reform would have saved $69 billion and avoided 944 million tons of CO2 emissions, while a five-year delay in subsidy removal causes an additional 100 million tons of CO2 emissions.

Summary: Cellulose upgrading with methanol to produce fuel-range alcohols involves complex reactions, such as C-C coupling, C-O scission, and C-C scission, as observed in the conversion of 1,2-propanediol and methanol over CuMgAlOx catalyst. The selectivity of different products is influenced by the reaction orders with respect to hydrogen, 1,2-propanediol, and methanol, as well as the apparent activation energies for various pathways. The rate determining step in C-C coupling is found to be associated with the nucleophilic attack by 1,2-propanediol, and the co-feeding of formaldehyde affects the rates of C-C coupling, direct C-C scission, and esterification reactions.

Summary: In this study, we investigated the ethanol oligomerization process to higher alcohols and other oxygenates using a 0.3 wt. %Cu/Mg2.9AlO catalyst. We found that the selectivity towards diesel fuel precursor compounds increased with conversion until reaching a plateau at an ethanol conversion of around 70%. Alcohol selectivity followed the Schultz-Flory distribution at all studied conversions. We also observed that larger sized alcohols were mainly formed through chain-growth mechanisms, while higher esters were formed through a series reaction mechanism involving alcohols and aldehydes.

Summary: Food packaging often uses multilayer plastic films to achieve specific food protection goals. However, the production of these films generates large amounts of unrecyclable plastic waste. A proposed technology called STRAP enables the separation and recycling of the polymers in the films. This study evaluates the environmental benefits of STRAP compared to virgin film production using life cycle assessment methods.

Summary: Developing highly efficient bifunctional oxygen electrocatalysts is crucial for zinc-air flow batteries. Metal-organic frameworks (MOFs) and covalent organic polymers (COPs) have emerged as promising alternatives due to their designable and controllable atomic-level structures. However, their catalytic performances are limited by conductivity and catalytic activity. In this study, nanosheet FeNi-MOF and iron phthalocyanine rich COP hybrid materials are assembled through the pi-pi stacking effect to create highly efficient bifunctional electrocatalysts. The resulting catalyst exhibits superior catalytic performance and stability, making it a promising candidate for zinc-air flow batteries.

The modified e-CPA model demonstrated better performance and the hybridization with electrical conductivity models resulted in two predictive models for estimating the electrical conduction of dilute and concentrated electrolyte solutions. These predictive models showed relative average percentage deviations (AARD) of 11.15% and 13.87% over wide ranges of temperature and electrolyte concentration.
