Front Cover: Single processing methods hardly cover the vast range of parameters needed to obtain polymer materials with integrated functionalities for increasingly complex applications. This study combines injection molding with precision additive manufacturing to produce customized hybrid materials, in particular to achieve selective mechanical reinforcement of injection molded objects by overprinting with microstructures.

Front Cover: Taking the advantage of hydrophobic nature of PLGA and branched structure of POEGMEMA, enables to get physically cross-linked scaffolds. Physical cross-linking is achieved by aggregation of PLGA in aqueous media and formation of intra- and inter-molecular entangles between aggregated PLGA and branched POEGMEMA polymers. Thus, though high hydrophilic POEGMEMA content, robust polymeric scaffolds are obtained without using toxic reactions. More details can be found in article 2400112 by Elif Kaga and Sadik Kaga.

Front Cover: A novel core-sheath fiber structure made using pressurized gyration and where the thin sheath is loaded with garlic (Allium Sativum) eliminates bacteria. This is demonstrated by comparing the top half of the micrograph with the bottom half where the bacteria are virtually absent. The exploitation of natural materials like garlic in this way paves the way for a new generation of economical but very effective and safe wound healing patches. More details can be found in article 2400014 by Mohan Edirisinghe and co-workers.

Tailored ribbing structures are obtained by large-scale rolling in polymer PDMS thin-films by adding carbon nanotubes (CNT) inclusions, which significantly improved the mechanical behavior of systems subjected to dynamic compressive strain rates. A nonlinear explicit dynamic three-dimensional finite-element (FE) scheme is used to understand and predict the thermomechanical response of the manufactured ribbed thin-film structures subjected to dynamic in-plane compressive loading. Representative volume element (RVE) FE models of the ribbed thin-films are subjected to strain rates as high as 10⁴ s⁻¹ in both the transverse and parallel ribbing directions. Latin Hypercube Sampling of the microstructural parameters, as informed from experimental observations, provide the microstructurally based RVEs. An interior-point optimization routine is also employed on a regression model trained from the FE predictions that can be used to design ribbed materials for multifunctional applications. The model verifies that damage can be mitigated in CNT-PDMS systems subjected to dynamic compressive loading conditions by controlling the ribbing microstructural characteristics, such as the film thickness and the ribbing amplitude and wavelength. This approach provides a framework for designing materials that can be utilized for applications that require high strain rate damage tolerance, drag reduction, antifouling, and superhydrophobicity.
