Summary: This study investigates the ability of the frequency domain electromagnetic induction (EMI) method to generate physicochemical soil maps related to grapevine vigor. By using a flexible clustering approach and the in-phase components of EMI measurements, distinct soil zones with different physicochemical characteristics were successfully identified. It is worth noting that this approach does not rely on prior information or calibration of EMI measurements. Extensive soil texture and physicochemical measurements were used to compare the different zones identified. Additionally, the assessment of grapevine vigor using NDVI data revealed correlations with organic matter, nitrogen, CEC, pH, CaO, and copper concentration in one of the studied sites.

Summary: This study examined a water-soluble rigid rod polymer as a potential substitute for organic-soluble rigid rod polymers due to the difficulties in finding suitable solvents for the legacy polymers. The synthesis of a poly(lysine) with a short ethylene glycol side chain, PEGL, was replicated and characterized. It was found that PEGL exhibited aggregation, non-ideal rigid rod behavior, and varying lower critical solution temperature with salt concentration. These issues prevent PEGL from being used in fundamental polymer investigations.

Summary: This study systematically investigates the correlations between the physical properties of six carbon nanotube (CNT) yarns produced by different spinning methods, and their structures and the properties of the constituent CNTs. The results show that the electrical conductivity of the yarns increases with the effective length of the constituent CNTs and the density of the yarns, while the tensile strength is more influenced by the packing density of the yarns, indicating the relative importance of interfacial interaction.

Summary: In this study, a laboratory-scale experimental device was developed to explore the coupling merits of two traditional desorption technologies: steam-enhanced extraction (SEE) and electrical resistance heating (ERH). The results showed that injecting high-density steam into moist soil could fracture the soil matrix and lead to preferential steam flow. When ERH and SEE were combined, preheating the soil increased permeability and alleviated the problem of preferential steam flow. The injection of steam heated the soil and provided moisture for maintaining power stability in the ERH process. The combined method reduced energy consumption compared to ERH or SEE alone.

Summary: The objective of this study was to investigate the influence of shear rates on the properties of polyamide 6/multiwalled carbon nanotube composites. It was found that high shearing conditions in injection molding were unfavorable for the formation of intact filler network, resulting in lower electrical conductivity. A better filler distribution was observed under higher shearing conditions. Moreover, the tensile strength of the injection molded samples increased with higher filler concentrations, attributed to the preferential orientation and better distribution of carbon nanotubes.

Summary: The study demonstrated that Na-ETS-4 is highly selective for Hg2+ and can exchange over 90% of mercury in the fluid phase. The system with Hg2+/Na+/ETS-4 required more time to reach equilibrium in the presence of Na+ compared to TPA(+). The modeling based on mass action law and Maxwell-Stefan formalism successfully described the kinetic curves of mercury removal.

Summary: Composting of chicken manure, coffee husk, and monoammonium phosphate can produce slow-release NPK organomineral fertilizers with improved agronomic efficiency. The formulated fertilizers showed good nutrient availability, FTIR spectral signature, and capacity to release and supply NPK to maize. The OMFs significantly increased maize shoot biomass and phosphorus content compared to MAP-fertilized plants, especially in soils with higher organic matter content. Overall, composting of CM, CH, and MAP is a feasible strategy to nourish maize grown in highly weathered soils.

Summary: This study focused on the agronomic efficiency of biochar-based fertilizers (BBFs) and their synthesis routes, properties, and interaction with the soil-plant system. The results showed that BBFs synthesized using nitric acid had enhanced agronomic performance, while the addition of magnesium reduced phosphorus release in water. Furthermore, the study found that an appropriate phosphorus rate had a positive effect on the growth of maize and brachiaria grass. Therefore, BBFs have the potential to improve phosphorus use efficiency in soils.
