Summary: This paper presents results on the thermal decomposition of copper II salts in synthetic air and argon flow. It also investigates the influence of salt addition on the rheological properties and sintering behavior of ceramic samples. The microstructure evolution is described based on light and scanning electron microscopies coupled with stereological methods.

Summary: The simultaneous thermogravimetric-mass spectrometry analysis of pyrolytic decomposition of different metallurgical coals provided insights into the coking mechanism during the carbonisation process. The addition of phenolic resin to coal enhanced fluidity and thermal cracking, revealing the characteristics of gases evolved and helping to eliminate discrepancies in molecular weight components.

Summary: Global plastic consumption leads to the production of harmful microplastics that affect ecosystems. Polluted organic amendments impact agricultural soil quality and can pose risks to human health through incorporation into the food chain. The development of a methodology to regulate microplastic pollution is crucial for ensuring agricultural soil quality and food safety.

Summary: In this study, novel catalysts were synthesized by anchoring a representative transition metal oxide (TMO), CoMn2O4 (CMO), on kaolinite and halloysite matrixes. The catalysts exhibited higher reactivity, improved structural stability, and better durability compared to bare CMO. CMO/kaolinite showed higher structural stability while CMO/halloysite demonstrated better stability and durability.

Summary: The study focused on the thermal characteristics and behavior of rice husks under different atmospheres, as well as the potential emission of pollutants to the atmosphere. The results suggested that rice husks could be used as biofuel in industrial thermal equipment due to their acceptable calorific value, good thermal characteristics, and low gas emissions.

Summary: In this study, the sorption/desorption characteristics of Eu(III) ions onto halloysite and kaolinite were investigated. It was found that halloysite displayed a higher sorption capacity for Eu(III) than kaolinite in a weakly acidic environment, and the desorption efficiency increased with the increasing concentration of NH4+ ions. The desorption of Eu(III) ions from the two clay minerals is proposed to be governed by the attraction between the outer-sphere complexes and clay minerals when the NH4+ concentration is 0.002 mol/L.

Summary: The global consumption of plastic is increasing every year, leading to the generation of microplastics which affect air quality. This study developed a method to quantify PS microplastics in the atmosphere near an agricultural area, with potential contamination sources related to agricultural activities. The TGA-MS methodology was shown to have potential as a complementary technique for microplastics characterization.

Summary: This study aimed to quantify the concentrations of polystyrene microplastics in the smaller fractions, thoracic (PM10) and alveolar (PM2.5) in the air. The majority of polystyrene microplastics were found in the PM2.5 fraction, which is associated with severe cardiopulmonary and respiratory diseases. The main sources of these microplastics could be related to local agricultural practices.

Summary: This study characterized soil samples from different locations around the Gamalama volcano and discovered the presence of halloysite, allophane, and kaolinite. Short tubular structures with nanoscale dimensions were observed, with halloysite being found at a depth of 70 cm beneath the soil surface in almost all locations. The soil samples had a remarkably large surface area, potentially making them suitable as catalytic or photocatalytic-supporting materials in the future.

Summary: The palm oil industry produces biomass by-products with different chemical compositions and thermal decomposition behaviors, which have been studied to show the distribution of thermal decomposition products used to explain compositional differences in the system. Additionally, the presence of potassium element was found to catalyze the decomposition of biomass.

Summary: The thermal stability of two borate-based ionic liquids (BOB and DFOB) was investigated. The results suggest that DFOB exhibits higher stability than BOB, possibly due to the charge-stabilizing inductive effect of fluorine atoms.
