Summary: Covalent organic frameworks (COFs) are promising materials for various applications, and the ability to directly print COFs into desired geometries is crucial for their optimization and deployment. This study presents a method to print COFs with micron-scale resolution using a solution-processable colloidal ink. The ink formulation, based on low-volatility solvent benzonitrile, allows for homogeneous printed COF film morphologies. The ink is also compatible with other nanomaterials, enabling the integration of COFs into printable nanocomposite films. Proof-of-concept experiments demonstrate the successful integration of boronate-ester COFs with carbon nanotubes (CNTs) to create printable COF-CNT nanocomposite films with enhanced temperature sensing performance.

Summary: Friction stir additive manufacturing (FSAM) is used to fabricate nanoparticle reinforced aluminum matrix composites, optimizing material properties in terms of hardness and grain size. The dispersion of nanoparticles increases hardness and reduces grain size, while re-stirring and reheating in the stirring zone improves mechanical properties. Both nanoparticle size and volume fraction have significant effects on grain size and hardness.

Summary: The study evaluated the dimensional stability window of food inks for 3D food printing based on rheological measurements of their rigidities, providing guidance on likely stability of 3D-printed food items. The screening method shows promise for accelerating the development of 3D-printing food inks by narrowing down potential candidates before printing tests begin. No correlation was found between rheological properties and filament quality of the food inks, as hardening times for molten ink filaments varied significantly.

Summary: Three-dimensional bioprinting is a promising field in medical science that has enormous potential for manufacturing operative tissue structures. The quality of bioprinting results depends heavily on printing parameters and the selection of biomaterials that closely match the target structure. This study aims to determine and optimize printing parameters for hybrid bio-inks, with a focus on the composition of hydrogels. The results indicate that parameters such as air pressure, nozzle speed and diameter, and hydrogel composition significantly affect printing quality. The study also provides a systematic framework to assess the properties of amino acids and derivatives, which can be applicable to other areas of 3D bioprinting. The findings of this study are crucial for establishing 3D bioprinting as a comprehensive manufacturing solution for biopharmaceutical industries.

Summary: 3D printing is a promising technology for fabricating cost-effective and customizable objects. Research on bio-based inks with recyclable and eco-friendly properties is increasing due to the need to substitute fossil fuels as raw materials. In this study, ionogels and hydrogels were formulated for 3D printing using cellulose dissolved in [Emim] [DMP] at different concentrations. Rheological properties and printability were compared with a commercial ink, and the 4 wt% ink was found to have the best print resolution and fidelity. These 3D printed cellulose ionogels and hydrogels may have applications in the electrochemical and medical fields, respectively.

Summary: In this study, a van der Waals (vdWs) heterostructure was fabricated using ultra-high vacuum laser molecular beam epitaxy (LMBE) and vertical 2D stacking strategy. The introduction of UV light illumination significantly improved the electrical transport properties and NO2 sensing performance of the heterojunction-based device. The sensor exhibited comparable sensitivity, low detection limit, and excellent selectivity for NO2 gas with fast response and full recovery properties under UV light illumination. The mechanism of enhanced gas sensitivity was proposed based on energy band alignment.

Summary: Non-contact optical temperature detection has great potential in biological systems and microfluidics due to its superior spatial resolution, accuracy, and non-invasive nature. However, the thermal quenching of photoluminescence hinders its practical applications. In this study, a thermally enhanced green upconversion luminescence in Yb/Er/ZnGdO microflowers was achieved through a defect-assisted thermal distribution mechanism. Additionally, the Yb/Er/ZnGdO microflowers acted as self-referenced radiometric optical thermometers, demonstrating high sensitivity temperature detection. These findings provide a novel strategy for overcoming thermal quenching luminescence and promoting the application of non-contact sensitive radiometric thermometers.
