Article Abstract
Rapid temperature contrast hydrotherapy by water immersion has been utilized by athletes for effective sports recovery. However, its application at some training or competition venues is limited by high water consumption, bucky size, personal hygiene, and inconvenience. Here, a novel portable system equipped with highly effective, lightweight, and hygienic wearable fluidic fabric device is reported, that replaces direct water immersion. The measured heat transfer coefficient between the skin and the fabric is 98.5 W m K, which is 92% of that in direct water immersion at 10 °C and significantly higher than that by previously reported cooling garments. The core layer, a flexible heat transfer panel (FHTP), can switch between cold and hot modes (5-40 °C) over an area of 0.3 m. The contact condition between skin and the deformable FHTP has been considered in a new verified heat transfer model. Optimization of the parameters has resulted in excellent heat transfer performance. This fluidic fabric also holds potential in diverse applications, such as enhancing thermal safety and comfort in extreme environments (e.g., personal thermal management systems and fire-protection suits), supporting cryotherapy and thermotherapy in rehabilitation and healthcare, and simulation of total tactile sensations in virtual reality.

To address the growing demand for temperature control precision and uniformity in wafer processing, a specialized electrostatic chuck temperature control system based on thermal control coatings is proposed, aiming to enhance thermal management robustness and homogeneity. This study employs a zoned control methodology using metal-oxide conductive coatings on silicon carbide wafer heating plates. A quadrant-based thermal control coating model was established, and finite element analysis was conducted to compare temperature distribution characteristics across three geometric configurations: sectorial, spiral, and zoned designs.

In this study, potato slices were fried in four different vegetable oils (corn, olive, palm olein, and sunflower) to investigate how oil type influences the characteristics of potato chips. The diffusion coefficient of oils was attempted to be correlated with the final moisture, oil uptake, and textural parameters of potato chips. The diffusion coefficients were determined using two approaches.

This research proposes an advanced technique to manipulating milk flow and its thermal characteristics through a dynamic electromagnetic pathway, effectively managing the non-linear thermal behavior of milk. This study employs advanced artificial intelligence (AI) to create a sophisticated analytical framework for modeling the complex interactions between milk flow, hybrid nanoparticles (Ag-ZnO), and dynamic thermal conditions in a squarely activated electromagnetic tunnel. The research focuses on optimizing key steps in dairy manufacturing-microbial reduction and texture stabilization by analyzing the behavior of Ag-ZnO/milk under oscillating thermal amplification, incorporating radiant heat and Darcy drag effects.

With the exhaustion of fossil fuels, prior phase change materials are characterized by such drawbacks as poor thermal conductivity, weak shape stability, and high costs. Therefore, the preparation of phase change materials with brilliant thermal-insulating properties, high thermal conductivity, and leakage-free properties has emerged as a crucial research focus. Herein, a sericultural mulberry branch-derived (SMB) composite phase change material was prepared by deep eutectic solvent pretreated SMB and vacuum-assisted impregnated paraffin wax with cupric oxide (CuO).
