How does Fe2 become Fe3 when sulfide nano zero valent iron degrades organics?
5 answers
The transformation of Fe^2+ to Fe^3+ during the degradation of organics by sulfide nano zero-valent iron (S-nZVI) is a multifaceted process that involves various mechanisms, as elucidated by the research contexts provided. The core principle behind this transformation lies in the reactivity and interaction of S-nZVI with organic pollutants and the subsequent generation of reactive oxygen species (ROS) and other oxidative species. In the degradation process, S-nZVI exhibits high reactivity towards halogenated organic pollutants, where the sulfurization of nZVI enhances both its stability and activity, leading to effective pollutant degradation. The sulfurization process, as described, involves the formation of a core-shell structure or a mixture of FeS2 and nZVI, which significantly contributes to the degradation efficiency. The biological precipitation method developed for preparing S-nZVI, which avoids harmful chemical sulfidating agents, also plays a crucial role in enhancing the reactivity and selectivity of S-nZVI towards pollutants. The activation of strong oxidants like persulfate (PS) by nano-Fe^0, which is a component of S-nZVI, generates sulfate radicals (SRs) that possess higher oxidation potentials. This process is instrumental in the degradation of refractory organics, where Fe^0 acts as a catalyst. Similarly, the activation of peroxymonosulfate (PMS) and peroxydisulfate (PDS) by activated zero-valent iron (Ac-ZVI) coupled with Fe^3+ leads to the liberation of Fe^2+ as an active species for ROS generation, further facilitating organic degradation. The transformation from Fe^2+ to Fe^3+ occurs as part of the oxidative processes involved in the degradation of organics. The presence of Fe^3+ promotes the liberation of Fe^2+ from Ac-ZVI, which then participates in the generation of ROS. These ROS, including sulfate radicals, are responsible for the oxidative degradation of pollutants. As Fe^2+ is oxidized during these reactions, it is converted into Fe^3+, which can then be recycled back into the system to promote further Fe^2+ liberation and ROS generation, thus sustaining the degradation process. Moreover, the modification of nZVI with sulfur and other agents, as discussed across various contexts, not only improves the dispersity and stability of nZVI in aqueous solutions but also enhances its reactivity towards organic pollutants by facilitating the generation of oxidative species and the transformation of Fe^2+ to Fe^3+ during the degradation process. This transformation is crucial for the continuous and effective degradation of organics, making S-nZVI a potent material for the remediation of contaminated water and soil.
How water vapour permeability decrease by changing the structures from fibers to beads on string and then electrospraying?
8 answers
The transition from fibrous structures to beads-on-string (BOTS) configurations and finally to electrosprayed films significantly influences water vapor permeability (WVP) due to changes in morphology, surface area, and internal structure. In fibrous structures, the porosity and interconnected pore structure, as seen in electrospun nanofibrous polyurethane webs, can be tailored to achieve high water vapor transmission rates (WVTR) by optimizing electrospinning parameters. The introduction of beads in a BOTS configuration adds complexity to the structure, potentially altering the path water vapor must take to permeate through the material. The presence of hydrophilic beads on a hydrophobic string, as demonstrated by Tian et al., introduces segmented swelling and shrinking behavior in response to environmental humidity, which could temporarily affect the WVP by changing the structure's porosity and surface characteristics. Further morphological control through the Rayleigh instability technique and breath figure method allows for the creation of BOTS fibers with varying degrees of porosity, which can be precisely regulated to modify the material's WVP. The incorporation of carbon nanotubes in a beads-on-a-string nanostructure for electrode materials also hints at the potential for creating pathways that could either facilitate or hinder water vapor movement, depending on the orientation and connectivity of the beads and strings. Transitioning to electrospraying, which produces films with different densities and internal pore structures compared to fibrous and BOTS configurations, offers a distinct approach to controlling WVP. Electrosprayed pectin films, for example, exhibit more transparency and smoother surfaces but with more and smaller internal pores than films produced by casting, leading to a larger water vapor permeability value due to the increased surface area and porosity at the microscale. This indicates that while fibrous and BOTS structures provide a means to tailor WVP through morphological adjustments, electrospraying offers a complementary strategy by manipulating film density and porosity at a finer scale. Collectively, these studies illustrate a progression in material design from fibers to BOTS and electrosprayed films, each offering unique mechanisms for controlling WVP through structural modifications.

Agglomeration of CNTs has been observed to impact the mechanical performance negatively in high-CNT-percentage samples, while positively affecting electrical conductivity by forming networks for electron transport. Additionally, the study on CNT-reinforced composites highlighted the importance of understanding the effects of CNT agglomeration on elastic properties, emphasizing the need to control agglomeration for optimal reinforcement. Therefore, managing fiber agglomeration at higher concentrations is crucial for maintaining and enhancing the flexural modulus of polymers.
