Summary: Ice buildup is a persistent challenge in various industries, negatively affecting system performance. A new composite panel inspired by animal skin has been proposed, consisting of a nanofluid layer protected by a facesheet, which shows durable anti-icing and tunable photothermal properties. The viscous liquid layer beneath the facesheet alters ice adhesion to the surface, resulting in low ice adhesion strengths. By altering the fluid properties, additional functionalities can be endowed to the system, such as impact resistance and tunable photothermal properties, making it a promising multifunctional de-icing material.

Summary: Photons can be used as clean and abundant energy carriers for nanoactuation, but the response is often slow and energy efficiency is low. This study introduces the concept of robust nanoscale plasmonic dynamite using fullerene (C-60) incorporated nanoparticles, which can explode in nanoscale with the help of plasmon-enhanced photochemical and photothermal effects. This nanoexplosion generates powerful forces and high thermomechanical energy efficiency, making it a promising nanoengine for controlled mobilization of micro-objects on solid surfaces.

Summary: Solar energy, as a sustainable and widely available source of clean energy, has great potential for solving various issues. Nanofluids (NFs)-based direct absorption solar collectors have been widely used in energy-thermal conversion and wastewater purification fields. However, the low photothermal modulation efficiency of NFs limits the industrialization of solar collectors. In this study, a Fe3O4@Au composite structure is constructed using a coprecipitation method, and its optical and photothermal properties are systematically studied. The results show that the Fe3O4@Au NFs have a high solar energy-weighted absorption fraction and excellent solar energy harvesting ability.

Summary: In the past decade, there has been a growing interest in studying energy systems for the combined management of power vectors. Most of the published works focus on finding the optimal design and operations of Multi Energy Systems (MES). However, for newcomers to this field, understanding how to achieve the desired optimization details while controlling computational expenses can be challenging and time-consuming. This paper presents a novel approach to analyzing the existing literature on MES, with the aim of guiding practical development of MES optimization. Through the discussion of six case studies, the authors provide a mathematical formulation as a reference for building the model and emphasize the impact of different aspects on the problem nature and solver selection. In addition, the paper also discusses the different approaches used in the literature for incorporating thermal networks and storage in the optimization of multi-energy systems.
