This review highlights the latest developments of triply periodic minimal surface (TPMS) structures with aim system's energy utilization. TPMS have gained widespread recognition due to their significant heat transfer (e.g., enhanced area) and diverse mechanical properties structural stability), making them highly valuable in numerous thermal applications. A comprehensive survey design approaches, software tools, commercial materials, 3D printing techniques TPMS‐based is provided. Research gaps future perspectives for commercialization TMPS are identified. Moreover, potential applications augmentation management discussed. promising topologies exchangers on account intrinsically outstanding specific area. In this context, received considerable attention various applications, including exchangers, latent storage, hydrogen battery cooling/thermal management, membrane distillation. Besides, distinct proposed intensification photovoltaic/thermal collectors fuel cells. Meanwhile, new proposals using different sorption‐based notably adsorption cooling/desalination systems, atmospheric water harvesting, thermochemical desiccant air conditioning, nominated forward‐looking perspectives.

Gyroid structures exhibit significant potential in the fields of lightweight structural design, heat transfer, energy absorption, and biological applications. The use gyroid for implants dentistry is currently not sufficiently widespread. research encompasses compression testing, cellular investigation using a digital microscope, application artificial neural networks (ANNs) data gained from test. ANN study test phase which geometries are addressed by dental three-point bending tests novel this field. In field dentistry, compares usability five distinct design characteristics, including one model without structure. During we found that m1 had an average maximum strength 600 N, while m3 achieved 230 N. remaining models approximate 200 mechanical performance evaluation samples, 40% weight reduction was achieved. An has been developed to predict force experienced under certain deformations depending on infill ratio. This trained with obtained Using grid search Monte Carlo cross-validation, optimal multilayer perceptron structure determined have 12 neurons hidden layer, mini-batch size 8, learning rate 0.0001. Adam optimization algorithm used train model, constructed TensorFlow library. Evaluation metrics were model’s performance, results showed strong generalization capability high accuracy coefficient determination ( R 2 ) 0.997, mean squared error (MSE) 3.337E-05 kN , root square (RMSE) 0.005777 kN, absolute (MAE) 0.003633 dataset.

The utilization of hybrid electric propulsion concept in aviation offers a viable solution to address the limitations posed by relatively low energy density batteries fully aviation. These systems enable aircraft achieve significant range while simultaneously minimizing carbon emissions. While individual components Hybrid Electric Propulsion (HEP) system, such as motors and batteries, are designed with high efficiency, their integration presents challenge realm thermal management. Designing an efficient system for managing substantial waste heat generated sources effectively transferring it sinks during various flight phases is complex task. This becomes even more critical design must adhere weight limits prioritize safety considerations. In this review article, we performed systematic challenges related key elements management system. encompass every component or subsystem that contributes generic hybrid-electric includes generators, exchangers, power transmission systems, distribution storages, fuel cells, cooling fluids pipes, control pumps fans. Following identification challenges, paper provides comprehensive summary existing solutions have been offered pursued community challenges. Furthermore, also discusses emerging technologies each element, highlighting potential overcoming these
