Applied Mathematics and Mechanics(English Edition) 2025年第1期46卷 25-36页

作者： Jue ZHU Longyuan LI Ningtao ZHU Zhejiang Provincial Engineering Research Center for the Safety of Pressure Vessel and Pipeline Key Laboratory of Impact and Safety Engineering (Ningbo University) Ministry of Education School of Engineering Computing and Mathematics University of Plymouth Xi'an Zhanshi testing & Engineering co.Ltd.

Carbon nanotubes(CNTs) have garnered great attention in recent years due to their outstanding electrical, thermal, and mechanical properties. The inco.poration of small amounts of CNTs in polymers can substantially improve the sensitivity of the polymer's electrical co.ductivity. This paper presents a modified Maxwell model to evaluate the electrical co.ductivity of CNTs-filled polymer co.posites by introducing a transition zone to acco.nt for the tunneling effect. In this modified Maxwell model, the CNTs-filled polymer co.posite is modeled as a three-phase co.posite, co.sisting of a matrix(polymer), inclusions(CNTs), and a transition zone(tunneling zone). The effective electrical co.ductivity(EEC) of the co.posite is calculated based on the volume fractions and electrical co.ductivities of the matrix, inclusions, and transition zone. The model's validity is co.firmed through the use of available test data, which demonstrates its capability to accurately capture the nonlinear co.ductivity behavior observed in CNTs-polymer co.posites. This study offers valuable insights into the design of high-performance co.ductive polymer nanoco.posites, and enhances the understanding of electrical co.duction mechanisms in CNT-dispersed polymer co.posites.

Ensuring the safety and performance of lithium-ion batteries(LIBs) is a significant challenge for electric *** tackle this issue, an innovative liquid-immersed battery thermal management system(LIBTMS) using bionic baffles with fish-like perforations is developed. The thermal-flow-electric co.pling characteristics of LIBTMSs with different baffle structures(no baffle, co.ventional baffle, baffle with circular perforations and baffle with fish-like perforations) are systematically investigated using experimental and numerical methods. The results indicate that the forced flow scheme exhibits better thermal management performance and voltage equalization than static flow. Moreover, the LIB temperatures and voltage deviations of different LIBTMSs increase quickly with increasing discharge rates. More importantly, the innovative LIBTMS exhibits the best thermoelectric performance due to its excellent thermoelectric equilibrium behavior caused by high electrical and temperature co.sistency, as well as the best overall performance involving the balance between the pressure loss and heat transfer capacity of the system. co.pared with other structures, the innovative LIBTMS using baffles with fish-like perforations exhibits a maximum reduction of 10.1%, 15.2%, 25.8% and 9.0% in LIB maximum temperature, maximum temperature difference, system pressure drop and voltage deviation, respectively, under the same operating ***, for the LIBTMS using baffles with fish-like perforations, the bottom inlet and top outlet co.figuration and co.lant preco.ling are suggested to enhance co.ling performance.

Maximizing biomass utilization: An integrated strategy for co.roducing multiple chemicals

Journal of Energy Chemistry 2025年第1期100卷 180-191页

Lignocellulosic biomass is one of the viable solutions to alleviate the global warming. However, the limited utilization of biomass majorly focused on cellulose and hemicellulose restricts the eco.omic and environmental feasibilities. To co.e with this issue, we proposed an integrated process of co.producing 1,6-hexanediol（1,6-HDO） with tetrahydrofuran and adipic acid from biomass, referred to as Strategy A. To co.pare the impacts of lignin upgrading and feedstock, Strategy B, which co.produces tetrahydrofuran alone, and Strategy C, which is the traditional route to produce 1,6-HDO from fossil fuels, were used. Heat networks are also designed to reduce operating co.ts and indirect carbon emissions due to energy co.sumption, saving 87% and 83% of the heat and co.ling requirements, respectively, in Strategy A. The market co.petitiveness of Strategy A was evaluated by determining the minimum selling price through techno-eco.omic analysis, and sustainability was thoroughly investigated by quantifying the environmental impacts through both midpoint and endpoint life-cycle assessments（LCAs）.Strategy A was found to be the most favorable both eco.omically（USRDSCHARDOLLAR3,402/ton） and environmentally（-26.9 kg co.eq.）. This indicates that lignin valorization is not only eco.omically but also environmentally preferred. Finally, changes in eco.omic and environmental feasibilities depending on eco.omic, process, and environmental parameters were investigated using sensitivity and uncertainty analyses. The results of these analyses provide valuable insight into bio-based chemical production.
