3D-Printing of Freestanding Pure MXene Microarchitectures.

Since their discovery, titanium-based MXenes (TiCT) have attracted significant attention. Several studies have presented versatile, cost-effective, and scalable approaches for fabricating TiCT-based functional components. However, most previous studies only allowed the realization of 2D patterns or required diverse additives to produce 3D architectures.

Visualization of Microcapillary Tips Using Waveguided Light.

The microcapillary, a glass tube with a nano/micrometer scale aperture, is used for manipulating small objects across diverse disciplines. A primary concern in using the microcapillary involves tip breakage upon contact. Here, we report a method for visualizing the microcapillary tip, enabling precise and instant determination of its contact with other objects.

Emission Directionality of 3D-Printed Photonic Nanowires.

Photonic devices can be advanced by increasing the density of the integrated optical components. As the integration density increases, the potential for signal interference between adjacent components, optical crosstalk, becomes a concern. To address the crosstalk issue, it is crucial to identify the emission directionality of the integrated optical components.

Three-Dimensional Printing of Structural Color Using a Femtoliter Meniscus.

Structural colors are produced by the diffraction of light from microstructures. The collective arrangement of substructures is a simple and cost-effective approach for structural coloration represented by colloidal self-assembly. Nanofabrication methods enable precise and flexible coloration by processing individual nanostructures, but these methods are expensive or complex.
