• Impact of Accelerated Shock on Partial Discharge Characteristics at the Oil-Paper Insulation Interface of Transformers

  IEEE Transactions on Dielectrics and Electrical Insulation · 2025-10-23

  article

  The variation in pressure distribution at the oil-paper insulation interface of transformers under shock conditions leads to an enhancement of partial discharge, posing severe challenges to the reliability of transformer oil-paper insulation. In this study, an experimental platform for partial discharge testing at the oil-paper insulation interface under accelerated shock is established to investigate the partial discharge characteristics at different acceleration levels. The experimental results reveal that, compared to the zero-acceleration condition, accelerated shock significantly intensifies partial discharge at the oil-paper interface. With an acceleration of 10 m/s², the average discharge magnitude for the wire-plate electrode increases by 43.2%, while that for the needle-plate electrode increases by 20.0%. Both partial discharge magnitude and discharge frequency are observed to increase markedly with increasing acceleration. Furthermore, based on Comsol Multiphysics, a fluid-structure interaction model of the oil-paper insulation under accelerated shock is constructed. The simulation results indicate that accelerated shock induces fluctuations in the pressure distribution at the oil-paper interface, which alters the microbubble layer formation process and changes the number density of gas molecules at the interface. When the acceleration direction is negative, the pressure of the microbubble layer decreases, the solubility of gas reduces, and the bubble volume expands, resulting in an increased average free path of electrons and thus enhanced partial discharge. During cyclic positive and negative acceleration shocks, negative-direction acceleration is found to play a dominant role in promoting partial discharge at the oil-paper interface, thereby further aggravating the partial discharge process. This study can provide a reference for insulation design and protection of transformers under impact conditions.

• Unequal impacts of rising temperatures on global human sentiment

  One Earth · 2025-08-21 · 6 citations

  articleOpen accessSenior author

  Climate change poses growing risks to human well-being, yet research on its emotional impact has primarily focused on developed nations, obscuring potential global inequalities in psychological vulnerability. Here, we analyze over 1.2 billion social media posts from 157 countries to reveal how rising temperatures affect human sentiment worldwide and project future impacts under climate scenarios. We find a non-linear relationship where moderate warming can improve sentiment in cooler regions, but temperatures above 35°C negatively impact emotional well-being globally, with effects three times greater in low- and middle-income countries (25.0% decline in sentiment) than in high-income countries (8.1%). Even accounting for climate adaptation through income growth, we project global average sentiment will be 2.3% lower in 2100 than in 2019 due to future warming, indicating lasting psychological costs disproportionately burdening the world's poorest populations. These findings underscore the urgent need for climate policies that integrate emotional impacts and address inequalities in psychological climate vulnerability.

• Understanding housing market responses to stringent energy codes

  Real Estate Economics · 2025-03-16

  articleOpen accessSenior authorCorresponding

  Abstract Increased energy efficiency in buildings is essential to reducing carbon emissions and addressing climate change. Massachusetts' Green Communities Act of 2008, aiming for a 50% reduction in carbon emissions by 2030 and net‐zero by 2050, mandates the Stretch Energy Code for eligibility for state funding. This code requires new residential constructions to meet stringent Home Energy Rating System (HERS) Index scores. While these requirements benefit the environment, they may increase construction costs, affecting housing production and affordability. Using the staggered municipal adoption of the Stretch Energy Code to tease out causal relationships, we analyze the effects of the Stretch Energy Code on housing quantity and price across municipalities in Massachusetts. The results indicate that more energy‐efficient single‐family properties command a sales price premium of 4.0%, and the Stretch Energy Code adoption is associated with a decrease in the quantity of new single‐family housing starts. Approximately 45.5% of the price increase is due to higher willingness to pay for energy‐efficient homes, with the remainder attributed to reduced housing supply. Our article is particularly relevant as policymakers seek to balance the objectives and address the tensions between “E” and “S” in their “ESG” policy packages.

• Fluoride‐Free Adhesives for Low Surface Energy Fluorinated Substrates

  Advanced Functional Materials · 2025-12-03 · 1 citations

  articleOpen access1st author

  Abstract Designing high‐performance adhesives for fluorinated substrates, such as polytetrafluoroethylene (PTFE), remains a persistent challenge due to their ultra‐low surface energy and chemical inertness. Traditionally, strong adhesion to these surfaces has relied on fluorinated additives and per‐ and polyfluoroalkyl substances (PFAS), raising serious environmental and health concerns due to their persistence and toxicity. In response to increasing regulatory scrutiny and the rising demand for sustainable materials, a universal, fluoride‐free adhesive strategy based on copolymers featuring tertiary amine and amide functionalities is introduced. By leveraging strong dipole–dipole interactions afforded by carefully selected polar monomers, robust interfacial adhesion is achieved without the use of fluorinated components. The optimized copolymers, synthesized from 2‐(diisopropylamino)ethyl methacrylate and N,N‐dimethylacrylamide, demonstrate a record lap shear strength of 4.91 MPa on PTFE, significantly surpassing both commercial adhesives and previously reported systems. This work not only establishes a versatile and effective platform for fluoride‐free adhesion to challenging substrates but also advances the field toward next‐generation, environmentally responsible adhesive technologies.
