Axial Sulfur-Coordination Engineering Boosting Fe–N–C Catalysts For High-Performance Proton Exchange Membrane Fuel Cells, Lin Lin, Xiu-Xuan Hou, Zhe-Chen Fan, Yi-Xuan Yin, Wei-Yi Zhao, Kai Wei, Yu-Die Zhou, Li-Na Hou, Ying Wang, Hao Wan, Jun-Jie Ge

Journal of Electrochemistry

Fe-N-C catalysts have long suffered from kinetically sluggish oxygen reduction reaction (ORR) due to excessive adsorption strength toward oxygen intermediates and low site utilization. Heteroatom doping effectively accelerates ORR reaction kinetics through electronic structure modulation of metal sites for optimal intermediate adsorption, while chemical vapor deposition (CVD) enhances the turnover frequency (TOF) of active sites. Herein, we developed an FeSNC catalyst featuring abundant FeS₁N₄ sites via a dual-precursor CVD strategy. Experimental and theoretical analyses revealed that S incorporation disrupts the symmetric coordination of active sites, which optimizes OH* adsorption energies from 0.212 eV to 1.194 eV. Moreover, …

Deciphering The Role Of Binder Reaction Exothermicity In Thermal Runaway Of Lithium-Ion Cells, Wen Wen, Jing-Hong Zhou, Hao-Tian Lu, Xing-Gui Zhou

Journal of Electrochemistry

Thermal safety associated with lithium-ion cells as power sources remains a critical industry concern. A comprehensive understanding of how internal exothermic side reactions contribute to temperature rise is fundamental for accurately analyzing thermal runaway processes and predicting the thermal safety of lithium-ion cells. While various side-reactions, such as decomposition of solid electrolyte interphase layer, reaction between anode materials and electrolyte, reaction between cathode materials and electrolyte, and electrolyte decomposition, have been identified as heat generation sources in previous studies, the quantification of these reactions remains insufficiently standardized. Particularly, the impact of heat generation from binder decomposition (most commonly polyvinylidene difluoride) …

General Timing Games With Multiple Players, Alexander Matros, Vladimir Smirnov, Andrew Wait

Faculty Publications

We examine innovation in an n-player market-entry timing game with complete information and observable actions. In our novel multi-player setup, we allow for heterogeneous payoffs between players and leader payoff functions to be multi-peaked and non-monotonic, only requiring that followers’ payoffs are non-increasing with the time of the leader’s entry. We outline the conditions under which an n-player asymmetric game leads to standard second-mover advantage and preemption equilibria. In the context of a two-player game, we provide a comprehensive characterization of the pure-strategy equilibria for a general case. This includes the potential for the emergence of a new …

Flaked Paraffin Wax-Based Thermally Enhanced Composite Phase Change Materials: Toward A Highly Efficient Thermally Responsive Temperature-Regulating Asphalt Pavement, Feng Ma, Meng Pang, Zhen Fu, Xinye Jiang, Qiang An, Yingjie Hou, Wenhao Dong, Jenny Liu, Jiasheng Dai

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

To mitigate high-temperature distress in asphalt pavements and enhance thermal regulation, flaked paraffin wax (FPW) was selected as the PCM and incorporated into asphalt. To prevent leakage, FPW was microencapsulated (FPW-MPCM). To boost thermal conductivity, FPW-MPCM was combined with expanded graphite (EG) via two methods: One method involves using EG as an adsorption carrier to prepare EG-adsorbed FPW phase change microcapsules (FPW-MPCM-EG); the other method uses EG as the core material to prepare FPW/EG graphite phase change microcapsules (FPW/EG-MPCM). These four PCMs were added to asphalt at 3 %, 6 %, 9 %, and 12 % (wt.%) to prepare phase-change …

Entropy Of Metal/Solution Interfaces: Thermodynamic Framework, Theoretical Models, And Roles Of Interfacial Water, Zeng-Ming Zhang, Zi-Xi Liang, Jun Huang

Journal of Electrochemistry

Entropy is a basic thermodynamic property of the electrical double layer (EDL) at metal/solution interfaces, yet, its definition, measurement, and theoretical treatment are dispersed in the literature, and, in some cases, ambiguous. In this paper, we revisit the thermodynamic theory of EDL, from which two variants of entropy, excess entropy and formation entropy, are obtained and compared. In terms of the formation entropy, two calculation routes are validated in the context of a primitive EDL model, namely, the Gouy-Chapman (GC) model. After clarifying the concepts and calculation routes, we investigate interfacial water effects on the EDL entropy, using a refined …

It Shouldn’T Be Sexy: Exploring The Intersection Between Staged Intimacy And The Law, Spencer Darling

Denver Sports & Entertainment Law Journal

If your job requires you to passionately embrace your coworker after surviving the seat-riveting climax action of the third act, does that complicate your workplace’s sexual harassment prevention strategy? Most jobs do not require workers to make intentional intimate contact with their coworkers. Yet, in the entertainment industry, some jobs require not just intimate contact with coworkers but selling that contact as authentic. This staged intimacy, like staged violence, carries a risk that simulated conduct can result in real harm.

When produced without precaution, staged intimacy can create working conditions that constitute sexual harassment in violation of Title VII of …
