We used synchrotron X-ray tomography at the European Synchrotron Radiation Facility (ESRF) to non-invasively produce 3D tomographic datasets with a pixel-resolution of 0.7µm. Using volume rendering software, this allows the reconstruction of internal structures in their natural state without the artefacts produced by histological sectioning.

A micropunching lithography approach is developed to generate micro- and submicron-patterns on top, sidewall and bottom surfaces of polymer substrates. It overcomes the obstacles of patterning conducting polymers and generating sidewall patterns. This method allows rapid fabrication of multiple features and is free of aggressive chemistry.

FAQs
A high surface-area-to-volume ratio gives a greater proportion of the material access to its surrounding environment. This characteristic can influence transport behavior, surface chemistry, and interactions with adjacent materials. In engineering designs, it helps explain why these fibers are useful in filtration media, sensors, protective materials, and tissue scaffolds, where surface-mediated performance is important.
Electrospinning uses an electric field to draw a polymer solution or melt into a narrow jet. As the jet stretches, the solution loses solvent or the melt cools, allowing the material to solidify into a fiber. This sequence links electrical drawing, mechanical stretching, and phase change, providing a route for producing fibers with very small diameters.
Diameter, alignment, porosity, and surface chemistry are central design variables. Diameter and porosity affect transport behavior, while alignment can influence how a fiber assembly responds mechanically. Surface chemistry changes the character of interactions at the fiber interface. Adjusting these features allows engineers to tailor the same general material platform for different performance requirements.
In lightweight composites, these fibers can contribute filamentary reinforcement without requiring a large bulk material volume. Their small scale and adjustable alignment provide ways to tailor mechanical behavior, while their surface area can affect interactions within the composite. The engineering objective is to select fiber structure and surface characteristics that match the desired balance of weight and performance.
A typical sequence begins by preparing a polymer as a solution or melt, then exposing it to an electric field that draws out a fine jet. The jet stretches while moving away from its source, followed by solvent evaporation or cooling that solidifies the material. Controlling the resulting diameter, alignment, porosity, and surface chemistry supports application-specific designs.
They are useful when a design benefits from fine-scale structure, tailored surfaces, or controlled transport. Engineering applications identified for these materials include filtration media, sensors, tissue scaffolds, protective materials, and lightweight composites. The relevant fiber arrangement depends on the goal: porosity for filtration, surface properties for sensing, or mechanical characteristics for structural and protective functions.
