Abstract Stimuli‐responsive hydrogels have attracted much attention owing to the versatility of their programmed response in offering intelligent solutions for biomimicry applications, such as soft robotics, tissue engineering, and drug delivery. To achieve complexity biomimetic structures, two photon polymerization (2PP) has provided a means fabricating intricate 3D structures from stimuli‐responsive hydrogels. Rapid swelling hydrogel microstructures are advantageous osmotically driven...
The thermal and electrical performance of lithium-ion batteries subjected to liquid immersion cooling conditions in a dielectric fluid has been experimentally investigated this study. A single 26650 LiFePO4 cylindrical cell is completely immersed Novec 7000 charged discharged at onerous maximum rates up 4C 10C, respectively, where C can be defined as the measure rate which or relative its rated capacity. Immersion offers high heat transfer from cell's surface, particular when saturation...

Advancements in 3D print technology now allow the printing of structured acoustic absorbent materials at appropriate microscopic scale and sample sizes. The repeatability fundamental cell unit these metamaterials provides a pathway for development viable macro models to simulate built-up structures based on detailed individual units; however, verification such actual manufactured presents challenge. In this paper, design concept an benchmark metamaterial consisting interlinked network...
3D printing has been recognized as the future manufacturing technique by different industries. The properties of products manufactured using this depend upon large number factors, with print orientation being one among most important factors. Currently, there is no standard for build printed component. To date, analysis material conducted testing specimens in orientations. present work explores effect layer orientations on mechanical an SLA polymer material. Five orientations, i.e. 0°,...
This work aims to apply the Theory of Critical Distances (TCD) fatigue assessment additively manufactured (AM) Ti-6Al-4V material produced via selective laser melting (SLM) process. Modified alternatives traditional TCD methods are considered. In this sense, it is sought develop a prediction model that better suited assessing impact multiple stress-rising features which located in close proximity each other. Hereby, consideration has been given modelling process-inherent surface roughness...
The peak forces generated in friction stir welding impose substantial constraints on the process window of technology, affecting factors such as machine scale, design, and range applicable materials.

As-built, SLM-printed Ti-6Al-4V parts suffer from non-equilibrium, brittle microstructures due to the formation of metastable α'-phase martensite as a result printing process. Post-processing heat treatments are required alleviate residual stress and decompose into equilibrium phases. Using unconventional 'cyclical' treatment profiles, it is possible achieve bimodal microstructure opposed more typical lamellar achieved using conventional profiles. In present research, effect cyclical...
A variety of SiC-Based composites and monolithic ceramics were characterized by measuring their thermal diffusivity in the unirradiated, annealed, irradiated conditions over temperature range 400 to 1000°C.

Simple geometric distortions applied to the isometric Kelvin cell structures, (the tetrakaidecahedron), are shown result in equivalent materials with anisotropic Hooke's tensors. The material models estimated using a recently published inversion method where 21 independent elastic constants of tensor identified. In these geometries, some faces have been twisted and/or tilted. Numerical experiments suggest that distorted cells exhibit variations compression, shearing, shear-compression and...
