Single-walled carbon nanotubes (SWCNTs) remain one of the most promising materials of our times. One of the goals is to implement semiconducting and metallic SWCNTs in photonics and microelectronics, respectively. In this work, we demonstrated how such materials could be obtained from the parent material by using the aqueous two-phase extraction method (ATPE) at a large scale. We also developed a dedicated process on how to harvest the SWCNTs from the polymer matrices used to form the biphasic system. The technique is beneficial as it isolates SWCNTs with high purity while simultaneously maintaining their surface intact. To validate the utility of the metallic and semiconducting SWCNTs obtained this way, we transformed them into thin free-standing films and characterized their thermoelectric properties.

Abstract Covalent triazine frameworks (CTFs) have recently been demonstrated as promising materials for photocatalytic water splitting and are usually used in the form of suspended powder. From a practical point of view, immobilized CTFs materials are more suitable for large-scale water splitting applications, owing to their convenient separation and recycling potential. However, existing synthetic approaches mainly result in insoluble and unprocessable powders, which makes their future device application still a huge challenge. Herein, we report an aliphatic amine-assisted interfacial polymerization method to obtain free-standing, crystalline CTFs film with excellent photoelectric performance. The lateral size of the film was up to 250 cm2, the average thickness can be regulated from 30-500 nm. The crystalline structure was confirmed by high-resolution transmission electron microscope (HR-TEM), powder X-ray diffraction (PXRD), and small-angle X-ray scattering (SAXS) analysis. Intrigued by the good light absorption, crystalline structure, and big lateral size of the film, it was immobilized on a glass support that exhibited good photocatalytic hydrogen evolution performance (5.4 mmol h-1 m-2) and was easy to recycle.

Junyee, or Luis Yee, Jr., is a Filipino artist known for his large-scale and site-specific art installations, which reflect a deep awareness of ecology and environmental issues. He was born in the Philippine island of Agusan del Norte. Trained as a sculptor, Junyee has pioneered the use of materials readily available from nature for expansive, site-specific works that incorporate ephemeral material within specific locations, redefining site and space in the process. His inventive use of indigenous material—which he assembles into sprawling constellations of forms, swarms of objects, or networks of points which function like maps—conveys a concentrated appreciation of nature. His works Wood Things (1981) and Spaces and Objects (1986), for example, are sprawling assemblies of natural forms. Junyee’s installations bring the precarious state of our natural world to the fore; by incorporating natural objects into his art, he exhibits both resourcefulness and acute awareness of the finite state of natural resources. Junyee’s approach to art is characterized by a keen sense of the environment and astute knowledge of materials. Whether paintings composed with soot; free-standing and outdoor sculptures in wood or cast concrete; or sprawling site installations, Junyee’s work exhibits a feeling for form and inherent awareness of the ways art carves new spaces of experience.
