“…Rounded plates of silicified Bolidophyceae have a structure similar to the valves and scales of auxospores from centric diatoms (Mann and Marchant, 1989;Yamada et al, 2014). In other groups that display silica structures such as diatoms, chrysophytes, synurophytes, and dictyochophytes (Simpson and Volcani, 1981;Knoll and Kotrc, 2015;Finkel, 2016;Marron et al, 2016), silica formation takes place within a specialized membrane-bound compartment termed the Silica Deposition Vesicle (SDV) (Simpson and Volcani, 1981;Preisig, 1994). The origin and location of SDV differ among taxa.…”

Pico-and nano-phytoplankton (respectively, 0.2-2 and 2-20 µm in cell size) play a key role in many marine ecosystems. In this size range, Bolidophyceae is a group of eukaryotes that contains species with cells surrounded by 5 or 8 silica plates (Parmales) as well as naked flagellated species (formerly Bolidomonadales). Bolidophyceae share a common ancestor with diatoms, one of the most successful groups of phytoplankton. This review summarizes the current information on taxonomy, phylogeny, ecology, and physiology obtained by recent studies using a range of approaches including metabarcoding. Despite their rather small contribution to the phytoplankton communities (on average less than 0.1%), Bolidophyceae are very widespread throughout marine systems from the tropics to the pole. This review concludes by discussing similarities and differences between Bolidophyceae and diatoms.

“…To ensure efficient stress distribution, the unions between elements in both cases are based in the morphology of joints seen in nature, specifically in diatoms [41]. Notably, these natural structures often employ rounded and smooth joints, a design feature critical for mitigating stress concentrations.…”

A comparative study is presented, focusing on three different bioinspired design methodologies applied to a large-scale aeronautical tooling use case. The study aims to optimize the structure in terms of the first vibration mode, minimizing mass, and supporting operational loads. The development of lightweight metallic components is of great importance for industries such as aerospace, automotive, and energy harvesting, where weight reduction can lead to significant improvements in performance, efficiency, and sustainability. Bioinspired design offers a promising approach to achieving these goals. The study begins with an introduction to natural selection and various bioinspired concepts. It proceeds with a thorough review of the selected bioinspired design methodologies and tools, which are then applied to the chosen use case. The outcomes for each methodology were explored with respect to the design requirements. Subsequently, the most suitable design was selected according to the success criteria defined and its validation is explained. The manufacturing of this design was carried out using an advanced and novel approach specifically tailored to accommodate the large dimensions and complexity of the structure. Finally, modal testing was performed to validate the entire process, and the results obtained demonstrate the potential effectiveness of bioinspired design methodologies in achieving lightweighting and optimizing vibration modes for large-scale aeronautical tooling.

It is known that natural designs are more efficient and functionality-aimed than human designs. Historically, human beings have tried to mimic the way nature designs or the natural designs themselves. However, it turned out that it was usually too complex for the technology of the time. Today there exists the opportunity to mimic most natural designs due to advances in computational power and improvements in manufacturing methods. This can lead to a major weight reduction in the metallic components used, which is a key aspect in many engineering areas such as the aerospace, automotive or energetic industries. This study shows how these bioinspired designs can improve designer experience-based designs in several ways i.e.: mechanical behavior, part number reduction, weight reduction, etc. The components analyzed here will be metallic based on aluminum. It will be also shown the significance of the manufacturing-oriented design so the iteration times are reduced between the CAD and the CAM or the reduction of prototype manufacturing itself. Of course, these designs need to be validated mechanically via CAE and the CAM will also be used to avoid uncertainty during advanced manufacturing processes. Finally, the results of the real manufacturing process are going to be shown so the end-to-end cycle is complete.
