A novel fabrication method of vertically aligned carbon nanotubes by single-stage floating catalyst CVD The single-stage floating catalyst chemical vapor deposition (SS-FCCVD) method using the ferrocene route (e.g., ferrocene: catalyst and camphor: carbon source) offers significant but largely unexplored versatility for the production of carbon nanotubes (CNTs). Our study used the SS-FCCVD method to grow vertically aligned carbon nanotubes (VACNTs) on an alumina ceramic reactor surface at 850 °C under a nitrogen atmosphere. The experimental setup included a camphor/ferrocene ratio of 20:1 and a specific temperature gradient of 21 °C/cm. To minimize the catalyst agglomeration, we positioned the chemical sources at a distance of 15 cm from the inlet of the CVD reactor. Alumina ceramic surfaces proved highly effective for VACNT production, showing minimal agglomeration of iron particles, facilitating the formation of reactive sites essential for VACNT growth. The VACNTs grew readily on alumina ceramic surfaces, forming bundled, forest-like structures with segment lengths up to 1.2 mm and diameters around 60 nm. When compared to conventional substrates, the surface area of the reaction zone substrate increases by up to 705%, resulting in a significant boost in VACNT yield. A detailed evaluation of characterization results confirmed the growth mechanism and behavior of Fe particles such that carbon-encapsulated particles are attached to the inner and outer surfaces of the CNTs. These VACNT surfaces exhibited superhydrophobic properties, similar to the lotus leaf effect. The synthesized iron-dispersed CNTs exhibit exceptional efficiency in Chromium (VI) removal, with an impressive adsorption capacity of 0.206 mmol/m², positioning them as a promising solution for effective water treatment. This scalable SS-FCCVD method using the ferrocene route achieved the longest VACNTs reported to date.

The Influence of Mesopore Architecture in Hierarchical H-ZSM-5 on n-Butanol Dehydration Zeolites are among the most widely employed catalysts in the (petro-)-chemical industry. However, due to their elaborate microporous network, they are prone to diffusion limitations and deactivation. Several modification methods have been proposed to overcome these limitations, each exhibiting their benefits. In this work, two of the most promising strategies were combined, i.e., limiting the length of one of the crystal axes during synthesis to achieve a platelike morphology and introducing mesoporosity, creating a hierarchical platelike H-ZSM-5. The platelike morphology was obtained by adding urea as a growth modifier to the synthesis mixture, and mesopores were introduced in the platelike H-ZSM-5 through etching with a NaOH/TPAOH mixture. As a benchmark, the same etching procedure was applied to a commercial ZSM-5 counterpart. These materials were tested in the n-butanol dehydration, where the platelike morphology exhibited an improved catalytic performance, significantly increasing the activity per acid site and stability, and slightly increasing the selectivity toward the butenes. The generation of mesopores in commercial ZSM-5 also increased the activity per acid site but reduced the catalyst's stability, likely due to an increased amount of Lewis acid sites upon etching. When applying the same modification method to the platelike H-ZSM-5, much larger mesopores and some macropores were observed. These further increased the stability of the catalyst but barely affected the activity per acid site, presumably due to the already optimized catalytic performance of the platelike H-ZSM-5.

Designing soft and tough multiple-network elastomers: impact of reversible radical deactivation on filler network architecture and fracture toughness Polymer networks are crucial for engineering and biomedical applications; however, their excessive brittleness in the absence of viscoelastic dissipation limits their use in applications requiring high temperatures and water concentrations. Multiple-networks, consisting of a stiff and pre-stretched "filler" network phase embedded within a soft and extensible "matrix" network, offer a promising route to overcome this limitation; yet, the relationship between "filler" network architecture and fracture toughness remains unknown. Here, we synthesized three poly(ethyl acrylate) "filler" networks <i>via</i> free radical polymerization (FRP), RAFT, and ATRP, and assessed the interplay between "filler" network architecture, irreversible chain breakage, and fracture toughness by labelling their crosslinks with fluorogenic mechanophores. These networks had similar elastic chain densities but distinct chain length distributions and mesoscopic structures. They were used to prepare multiple-networks, whose structure and mechanical properties were evaluated using mechanical tests, confocal microscopy, reactive Monte Carlo, and coarse-grained molecular dynamics simulations. Our results reveal that "filler" networks synthesized by RAFT and ATRP yield more brittle multiple-networks than those made by FRP, primarily due to the reduced average extensibility of their "filler" network chains. Their narrower chain length distributions in the load-bearing phase promote strain hardening but compromise energy dissipation through molecular friction and chain breakage, as well as fracture toughness. Overall, these findings underscore the need for advanced gelation methods that provide control over elastic chain distributions within networks, as, without such improvements, the use of RAFT and ATRP may result in long curing times, opacity, and a greater tendency to fracture.

Pickering Emulsion Biocatalysis with Engineered Living Cells for Degrading Polycarbonate Plastics The efficient degradation of plastics remains a pressing environmental challenge due to their inherent resistance to breakdown. While biocatalysis offers a promising approach for sustainable and effective plastic degradation, the inherently low solubility of plastics in aqueous systems severely limits the efficiency of enzymatic reactions. To address this issue, we developed a biocompatible polymer coating strategy to engineer living cell surfaces, enabling the stabilization of Pickering emulsions for over 192 h and significantly enhancing plastic accessibility to biocatalysts. Leveraging this platform, Escherichia coli (E. coli) cells containing overexpressed Candida antarctica Lipase B performed well by dispersing at the emulsion interface of water and toluene, facilitating the efficient biodegradation of polycarbonate (PC) plastics. Under optimized reaction conditions (pH 9, 45 °C), this Pickering emulsion system achieved efficient PC degradation, producing up to 4.5 mm bisphenol A within 72 h-far exceeding the performance of biphasic systems using native E. coli cells. The findings highlight the transformative potential of surface-engineered whole-cell catalysts in addressing environmental challenges, particularly plastic waste remediation.

Antimicrobial packaging: mechanisms, materials, incorporation methods, strategies, biodegradability, and smart innovations – a comprehensive review The increasing demand for sustainable food preservation solutions has highlighted the potential of antimicrobial packaging to extend shelf life and enhance food safety. Conventional packaging materials contribute to environmental pollution, while microbial contamination continues to threaten food security. This review addresses these challenges by exploring antimicrobial packaging systems combining active agents with biodegradable polymers to tackle foodborne pathogens and environmental pollution. Antimicrobial agents, including natural extracts, organic acids, enzymes, bacteriocins, and nanomaterials, which inhibit microbial growth and alter cell membrane permeability, are commonly used in antimicrobial packaging. Incorporation techniques like coating, extrusion, and electrospinning are evaluated for their role in optimizing antimicrobial functionality. Strategies to balance functionality with environmental impact are critically evaluated, focusing on material performance and release mechanisms. The use of biodegradable polymers in these packaging systems ensures that they decompose naturally after use, reducing plastic waste, and promoting sustainability. Smart packaging, integrated with indicators and sensors for pH or temperature, enables real-time monitoring of food conditions, empowering consumers and stakeholders with actionable insights throughout the supply chain. Antimicrobial packaging demonstrates significant potential in addressing food preservation and sustainability, the high costs associated with advanced materials, incorporation methods, and smart innovations also limit the widespread adoption of these technologies, particularly in developing countries. Scaling up production while maintaining the efficacy and stability of antimicrobial components also poses significant technical challenges. Future research must focus on developing cost-effective, scalable, and regulatory-compliant antimicrobial packaging solutions that balance performance, safety, and environmental sustainability to facilitate global implementation.
