In the case of plasma-assisted combustion (PAC), a range of combustion properties are significantly affected by the introduced and absorbed microwave power. MIPs are well-studied in the case of mono-component gases, but less knowledge is available regarding the effect of introduced microwave power on multicomponent gases, like in the case of combustion. Previous research has primarily relied on the effect of introduced microwave power on the flammability limits and the flame speed enhancement during fuel-lean conditions, but less knowledge is available on the effect of introduced microwave power on the flue gas components. Here, we report a quantitative analysis of dry flue gas of premixed methane (CH4)-air flame coupled with 2.45-GHz microwave power using a self-designed mono-mode plasma cavity. A rapid increase in NOx concentration in the flue gas was found by the formation of plasma. The carbon dioxide concentration in the dry flue gas is found to decrease with the applied microwave power to the premixed CH4-air flame, while the oxygen concentration increases, which can be originated from the flame temperature increase. This is also supported by the rotational temperature calculations of OH radicals, which are based on the flame's spectral emissivity measurements.

This study, conducted through a meticulous PRISMA-guided literature review, spans the decade from 2013 to 2023, focusing on publications from the Scopus and Web of Science databases. The NOISE analysis model guides the exploration, emphasizing the Needs, Opportunities, Improvements, and Strengths in upskilling educators for the digital age. By synthesizing findings, this review highlights the multifaceted nature of digital competence, emphasizing its critical role in the knowledge society. Sustainable innovation emerges as a complex yet essential concept for future digital competencies. Key findings underscore the imperative for a continuous upskilling of educators and the transformative potential of STEAM pedagogy in fostering a holistic, transdisciplinary approach to education. The NOISE analysis offers practical insights, paving the way for future research directions, including the development of a robust conceptual framework for STEAM-based pedagogy. This review contributes by adding a culturally sustaining education framework for STEAM, which adds to existing knowledge by elucidating the symbiotic relationship between STEAM education, digital competence, and sustainable innovations, providing a nuanced understanding crucial for navigating the evolving educational landscape.

Plants used for phytoextraction are promising materials for the recovery of metals, but the biomass needs to be reduced to a manageable amount and volume prior to the extraction process. This paper investigates the combustion process of biomass focusing on NMs and REEs flow. The plants harvested from a brownfield land were pelletized and incinerated in a fixed-grate pilot-scale boiler, meanwhile, solid remains from various points in the combustion and flue gas system were captured and analyzed. The results show that levels of NMs in deposited ash and fly ash are greater than in bottom ash. Meanwhile, the higher REE concentration in bottom ash compared to that in other solid residuals demonstrates the less ability of these compounds to escape from the combustion chamber. Generally, the concentrations of REEs and NMs in the solid residues are significantly higher compared to biomass. SEM-EDS analyses of the contaminated solid remains indicate that gold forms individual particles with purity higher than 95 wt% in the bottom ashes, and this finding adds novel insights into gold phytomining.
