Article Abstract
Energy materials are essential for addressing global energy challenges, and their design, recycling, and performance optimization are critical for sustainable development. To efficiently rise to this occasion, advanced technology should be explored to address these challenges. This review focuses on the potential of ultrafast thermal engineering as an innovative approach to the design and recycling of energy materials and systematically examines ultrahigh temperature shock's origins, mechanisms, and developmental progress, clarifying fundamental differences between the Joule heating and carbothermal shock modes. Recent advancements in lithium/sodium battery electrode fabrication, catalyst synthesis, and battery recycling by this technology are comprehensively summarized to highlight the processing parameters, structural modulation mechanisms, and underlying principles. The review also explores the mechanisms of ultrahigh temperature shock processes, their scalability, and their environmental and economic implications. Notably, a mechanistic insight into the dynamic coexistence of Joule heating and carbothermal shock in UTS is proposed, which may synergistically govern structural evolution in poor conductivity/insulating materials. This review ultimately aims to drive the development and application of ultrafast thermal engineering in the energy materials field.

Integration of ultrathin, high-quality gate insulators is critical to the success of two-dimensional (2D) semiconductor transistors in next-generation nanoelectronics. Here, we investigate the impact of atomic layer deposition (ALD) precursor choice on the nucleation and growth of insulators on monolayer MoS. Surveying a series of aluminum (AlO) precursors, we observe that increasing the length of the ligands reduces the nucleation delay of alumina on monolayer MoS, a phenomenon that we attribute to improved van der Waals dispersion interactions with the 2D material.

Silk fibroin (SF)-based flexible electronic/photonic materials have gained great attention in wearable devices and soft sensors. However, it remains challenging to understand the molecular interaction mechanisms and subsequently fabricate SF-based flexible materials that exhibit fluorescence, humidity sensitivity, and conductivity properties. In this study, by incorporating lanthanide europium ion (Eu), the design and fabrication of a flexible, fluorescent, and conductive SF membrane was proposed.

This work assesses the current characterization framework of single-use personal protective equipment (PPE) per recognized consensus standards and presents a novel quantitative approach to refining characterization of barrier materials and predicting PPE performance. Scanning electron microscopy (SEM) and image analysis software (Diameter J) were used to examine the microscopic fiber and pore structure of filter layers of surgical N95 filtering facepiece respirators, before and after exposure to chemicals used in decontamination modalities (vaporized hydrogen peroxide or ozone). The effect of porosity on penetration was assessed by bacterial filtration efficiency (BFE) testing.

In contrast to metal ions that have been routinely used to construct metal-organic frameworks (MOFs), anions have rarely been used as essential coordination centers in supramolecular organic frameworks (SOFs). In this work, we present a SOF, , based on the coordination of chloride anions and a flexible oligopyrrole. Owing to the multiple interactions between individual oligopyrrole molecules and an A-B-C-style stacking of the 2D honeycomb layers, crystalline exhibits reasonable thermal stability and retains its structure upon desolvation.
