Summary: Synthesized single-walled carbon nanotubes (SWCNTs) effectively delay asphaltene precipitation and reduce the size distribution of asphaltene aggregates. The highest dispersion efficiency value of 93.5% is achieved at a concentration of 100 ppm. The large surface area of SWCNTs and strong pi-pi interactions with asphaltenes contribute to their efficient control of asphaltene precipitation/aggregation.

Summary: We investigated the liquid crystal phase behaviors of sodium cholate-stabilized single-walled carbon nanotube (SWCNT) aqueous dispersions with different SWCNT aspect ratios. The isotropic-to-nematic phase transition occurs at a lower concentration for the SWCNT dispersion with a larger aspect ratio, as expected by the Onsager theory. A well-aligned film was successfully fabricated from the dispersion with a higher SWCNT aspect ratio using simple blade coating. We also prepared SWCNT dispersions with different surfactants, sodium deoxycholate, and sodium taurodeoxycholate, to change the surface condition of SWCNTs, which may affect the LC transition concentrations.

Summary: Carbon nanomaterials such as graphene and carbon nanotubes have attracted significant interest due to their extraordinary properties, with the potential to play a key role in future applications. The sensitivity of carbon nanostructures to chemical stimuli allows for enhanced charge propagation capabilities, as seen in the impact of bromine addition on the electrical and thermoelectric properties of single-walled carbon nanotube films. Experimental results show a two orders of magnitude enhancement in thermoelectric capabilities through sonication-assisted introduction of Br2 into the SWCNT network, with computational analyses revealing the dopant's influence on electronic and charge transport properties.

Summary: In this study, the exfoliation of graphite to graphene nanoplatelets (GnP) in a molten salt medium was investigated. The process yielded large-sized GnP with low defect density without the need for mechanical force. The effect of the surface tension of the molten salt on graphite exfoliation efficiency was examined, and it was found that the salt with the lowest surface tension (CsCl) facilitated total exfoliation of graphite to GnP.

Summary: Interactions between polymers and surfactants in aqueous solution have significant implications in physical chemistry and industrial applications. By synthesizing two ionic derivatives from recycled cellulose, we explored the interactions of these polymers with different types of surfactants commonly used in the textile industry. The results showed that oppositely charged polymer/surfactant mixtures exhibited strong associations, while similarly charged mixtures showed minimal interactions except for the QC/CTAB system. Furthermore, the P/S mixtures significantly enhanced the hydrophilicity of a hydrophobic textile substrate at lower surfactant concentrations compared to surfactant alone.

Summary: The use of additive manufacturing (AM) enables the rapid creation of complex structures, including heat sinks and heat exchangers, for efficient heat dissipation. Researchers have developed a method using vat photopolymerization (VPP) and graphene-based thermally conductive filler to prepare heat sinks with high thermal conductivity (TC). By stabilizing graphene nanoplatelets (GNP) with a fiber-like clay filler, phase separation is prevented, allowing for a composite with a relatively high GNP concentration of 2.0 wt % and a 160% increase in TC compared to the pristine polymer. This printing technique also yields a material with anisotropic TC, with a cross-plane/in-plane (TC/TC=) ratio of 1.6, beneficial for thermal management systems.

Summary: This study proposes a novel conformal coating with enhanced thermal conductivity for effective heat dissipation from hot spots on printed circuit boards. By loading a polymer with graphene nano-platelets (GnP), a heat-dissipating composite with two orders of magnitude higher thermal conductivity (33 W/m K) is created. Experimental results show that the temperature of the component significantly decreases when the coating is applied, with a temperature drop of up to 35 degrees C under the given conditions. Numerical simulations provide further insights and confirm the experimental findings. The thin conformal coating can easily be used for thermal management in various applications in the electronic industry.

Summary: Hydrogen, a promising renewable energy source, poses challenges in industrial processes due to its ability to penetrate metals and cause embrittlement, leakage, and explosion risks. This study investigates the combined effect of a polymer liner loaded with graphene and unsaturated organic molecules in reducing hydrogen diffusion. The approach involves creating a hydrogen barrier using graphene nanoplatelets and chemically absorbing hydrogen using unsaturated organic molecules. The study finds that both graphene and unsaturated organic molecules significantly decrease hydrogen diffusion, and the presence of graphene allows hydrogen to migrate over its surface to reach the unsaturated molecules. Additionally, the study demonstrates that a polymer loaded with unsaturated organic molecules can serve as a visual hydrogen sensor. These findings provide important principles for designing functional materials for hydrogen detection, transportation, and storage.

Summary: This study investigates the relationship between the morphology of PMMA monopolymers and PMMA-PHEMA copolymers with the expected nature of surfactant-free microemulsions (SFMEs) before polymerization. It is found that previously mesostructured, surfactant-free mixtures can produce porous polymers of different morphologies, while unstructured, oil-rich regions lead to solid, transparent polymers without nanostructured morphologies. Additionally, a surfactant-based reference system shows similar phase behavior and polymer morphologies as the comparable surfactant-free system, indicating the importance of the hydrotropic behavior of HEMA in this system.
