Summary: This study focuses on using engineered low-cost activated carbon nanoporous material from Nerium Oleander fruit seeds for CO2 adsorption. The study finds that the adsorption efficiency decreases with increasing temperature and flow rate, while the height of the adsorbent column enhances CO2 removal. The activated carbon material shows a promising adsorption capacity of 48.6 mg CO2/g at 25℃, packed into a 5 cm column height with a flow rate of 25 mL/min, which is higher than the starting material (14.1 mg CO2/g). The material can be reused for up to 2 cycles after being exhausted more than 50% after cycle 2. Therefore, the study suggests that activated carbon materials prepared from Nerium Oleander seeds can effectively remove CO2 gas for a sustainable future.

Summary: The modifications in the pore network of evaporation-induced self-assembled microspheres of silica nanoparticles with varying loadings of polyethyleneimine (PEI) were investigated using positron annihilation lifetime spectroscopy (PALS) and small-angle X-ray scattering (SAXS). The dynamics of the loaded PEI in the pore network were studied using temperature-dependent broadband dielectric spectroscopy. The results showed that the pore size and volume increased with increasing PEI loading, followed by a decrease due to the modification in the clustering behavior of nanoparticles and filling of pores with excess PEI.

Summary: Understanding the molecular mechanism of gas adsorption in interconnected porous carbon is crucial for designing engineered materials with maximum gas storage capacity and kinetics for carbon capture applications. The synthesis of novel macro-meso-microporous carbon (M3C) nanospheres with interconnected pore structures allowed for fast CO2 adsorption and high capture capacity. In situ small-angle neutron scattering (SANS) revealed that the macro- and mesopores of M3C facilitate fast diffusion of CO2 molecules, leading to densification and fast diffusion in the macro- and mesopores until complete filling.

Summary: Immobilization of biomolecules into porous materials can improve their stability and ease of reuse. Metal-Organic Frameworks (MOFs) are promising for immobilizing large biomolecules, but their spatial arrangement within the pores is still not fully understood. In this study, researchers used in situ small-angle neutron scattering (SANS) to investigate the spatial arrangement of green fluorescent protein in a mesoporous MOF, revealing that protein molecules form assemblies through adsorbate-adsorbate interactions across pore apertures. This finding provides a crucial foundation for understanding protein structural basics in the confinement environment of MOFs.

Summary: In order to provide early warning against gas leakage accidents, a thin paper-like carbon nanotube (CNT) aerogel gas sensor was fabricated. The sensor showed excellent sensitivity for toxic gases like NO2 and methanol in the concentration range of 1-100 ppm, with a remarkable limit of detection of 90 ppb. Even after bending and crumpling, the sensor consistently responded to toxic gases. Through annealing at different temperatures, the sensing characteristics of the CNT aerogel film can be switched due to the change in the semiconductor nature of the film.

Summary: Manufactured graphite is commonly used for in-core components of molten salt reactors and fluoride salt-cooled high-temperature reactors. However, the porous nature of nuclear graphite can allow molten salts to intrude into the graphite's pores and impact its properties. In this study, neutron imaging was used to assess the penetration and distribution of FLiNaK salt in various graphite grades. The results showed that salt penetration and density distribution depended on the microstructural properties of the graphite grade.

Summary: The jamming of colloidal particles in dried droplets is influenced by various parameters, and substrate wettability plays a crucial role. Evaporating droplets on wettable surfaces can enhance the velocity of colloidal particles during drying. This study investigated whether the jamming of colloidal particles would exhibit increased velocity during the evaporation of droplets on superhydrophobic surfaces and air-suspended spray colloidal droplets. The results showed that the transition from ordered to random arrangement of colloidal particles is due to the increase in particle velocity during evaporation.

Summary: This study demonstrates the improvement of mechanical properties and reduction of coefficient of thermal expansion (CTE) in graphene oxide (GO)/epoxy (EP) nanocomposites by enhancing the interface between GO and EP through functionalization and incorporating rigid-flexible interphases. The results reveal that the SiO2-PEA-GO hybrid exhibits better strengthening and toughening effects, as well as lower CTE, compared to the PEA-GO hybrid due to the presence of rigid-flexible interfaces with higher bonding strength and better energy dissipation mechanisms. Additionally, the nanocomposites with longer polyetheramine (PEA) molecules in the rigid-flexible interphases demonstrate higher strength and toughness, while maintaining a lower CTE. This work provides a promising strategy for constructing adjustable flexible-rigid interfacial structures and offers potential in developing GO/EP nanocomposites with high mechanical properties and low CTE.
