| 1 | Characteristic Rainfall for Warning of Debris Flows显示文摘A characteristic rainfall is introduced to overcome the difficulties encountered in determining a critical rainfall value for triggering debris flow.The characteristic value is defined as the rainfall at which debris-flow occurrence probability shows a rapid increase,and can be used as a warning rainfall threshold for debris flows.Investigation of recorded debris flows and 24-hour rainfall data at Jiangjia basin,Yunnan Province,in southwestern China,demonstrates the existence of such a characteristic rainfall.It was found that the characteristic rainfall corresponds to the daily rainfall of 90% cumulative probability by analyzing the basin's daily rainfall histogram.The result provides a simple and useful method for estimating a debris-flow warning rainfall threshold from the daily rainfall distribution.It was applied to estimate the debris-flow warning rainfall threshold for the Subaohe basin,a watershed in the 2008 Wenchuan earthquake zone with many physical characteristics similar to those of the Jiangjia basin. | HU Kaiheng Cui Peng Wang Chuanchang Li Yong Lu Xiaobing | 2010 | Journal of Mountain Science2010，7，3： | 11 |
| 2 | Stearic Acid/Copper Foam as Composite Phase Change Materials for Thermal Energy Storage显示文摘The application of stearic acid in the latent thermal energy storage(LTES) systems is hindered due to its lower heat transfer rate. Stearic acid(SA) was blended with copper foam(CF) of pore numbers per inch(PPI) of 5, 20, and 40 to prepare composite phase change materials via a molten impregnation method. The thermal physical properties including latent heat, phase change temperature, and thermal energy storage density of composites were characterized. The thermogravimetric analysis indicated that the loadages of SA of SA/CF(5 PPI), SA/CF(20 PPI), and SA/CF(40 PPI) were 74.69%, 71.03%, and 63.54%, respectively;The latent heat of SA/CF(5 PPI), SA/CF(20 PPI), and SA/CF(40 PPI) were determined to 139.9 J·g^-1, 132.7 J·g^-1, and 117.8 J·g^-1, respectively. Meanwhile, the infrared thermal images of SA and SA/CF composites were provided to demonstrate the thermal energy storage and dissipation capability intuitively by the temperature response and surface temperature distribution. The infrared thermal images indicated the addition of CF also reduced the fluidity of liquid SA, and the SA/CF(40 PPI) had better internal heat transfer uniformity and thermal diffusion performance than SA/CF(5 PPI) and SA/CF(20 PPI). All these thermal properties suggested SA/CF(40 PPI) has the potential application in the latent thermal energy storage. | LI Chuanchang ZHAO Xinbo ZHANG Bo XIE Baoshan HE Zhangxing CHEN Jian HE Jianjun | 2020 | Journal of Thermal Science2020，29，2： | 5 |
| 3 | Mica-stabilized polyethylene glycol composite phase change materials for thermal energy storage显示文摘Mica was used as a supporting matrix for composite phase change materials(PCMs)in this work because of its distinctive morphology and structure.Composite PCMs were prepared using the vacuum impregnation method,in which mica served as the supporting material and polyethylene glycol(PEG)served as the PCM.Fourier transform infrared and X-ray diffraction analysis confirmed that the addition of PEG had no effect on the crystal structure of mica.Moreover,no chemical reaction occurred between PEG and mica during the vacuum impregnation process,and no new substance was formed.The maximum load of mica-stabilized PEG was 46.24%,the phase change temperature of M_(400)/PEG was 46.03℃,and the latent heat values of melting and cooling were 77.75 and 77.73 J·g^(−1),respectively.The thermal conductivity of M_(400)/PEG was 2.4 times that of pure PEG.The thermal infrared images indicated that the thermal response of M_(400)/PEG improved relative to that of pure PEG.The leakage test confirmed that mica could stabilize PEG and that M_(400)/PEG had great form-stabilized property.These results demonstrate that M_(400)/PEG has potential in the field of building energy conservation. | Dongyao Zhang Chuanchang Li Niangzhi Lin Baoshan Xie Jian Chen | 2022 | International Journal of Minerals,Metallurgy and Materials2022，29，1： | 3 |
| 4 | Multiple structure graphite stabilized stearic acid as composite phase change materials for thermal energy storage显示文摘This paper used 3 types of graphite with different physical structures as the porous matrix to prepare composite phase change materials(PCMs),and investigated their photo-thermal conversion performance and application in battery thermal management.Multiple structure graphite minerals,including microcrystalline graphite(MG),scale graphite(SG),and expanded graphite(EG)were used as porous matrix,while stearic acid(SA)acts as the phase change material.The vacuum impregnation method was applied to prepare SA/MG,SA/SG,SA/EG,and SA/MG1,and SA/EG1was/were prepared by the ethyl alcohol method.Results show that the thermal conductivities of all composite phase change materials were 10.82 to 22.06 times higher than that of the pure SA.Thermogravimetric(TG)analysis showed that the loadages of SA were 43.61%,18.74%,and 92.66%for SA/MG,SA/SG,and SA/EG respectively.The load rates of SA were 18.98%and 18.88%for SA/MG1 and SA/EG1,respectively.For the 3 types of graphite materials of different dimensions,the BET(Brunauer,Emmett,and Teller)surface area determines the maximum load of SA.The Fourier-transform infrared(FTIR)and X-ray diffraction(XRD)results indicated that there was good compatibility between the SA and the supports.The SA/EG1 has better thermophysical properties in heat energy storage and release process.The thermal infrared images show that SA/EG1 has higher sensitivity to the temperature changes.SA/EG1 has better photo-heat conversion performance than SA/SG and SA/MG1 attributed to the multilayer structure of EG.SA/EG has better thermal management performance in the Li-ion batteries discharge process. | Xinbo Zhao Chuanchang Li Kaihao Bai Baoshan Xie Jian Chen Qingxia Liu | 2022 | International Journal of Mining Science and Technology2022，32，6： | 2 |
| 5 | Evaluation of stearic acid/coconut shell charcoal composite phase change thermal energy storage materials for tankless solar water heater显示文摘This work presents a cost-effective and environment-friendly form-stabilized phase change material(PCM)and corresponding solar thermal application in the tankless solar water heater(TSWH).Coconut shell charcoal(CSC)as supporting material was modified by moderate oxidant of H_(2)O_(2)with different concentrations,and then sta-bilized stearic acid(SA)to prepare composite PCMs through vacuum impregnation.It found that CSC support causes a 15.70%improvement of SA loadage after treated by 15%H_(2)O_(2)due to coefficient enhancement by phys-ical interaction and surface modification.The modified CSC 15 support appears more super macropores which contribute to the impregnation of SA than non-modified CSC 0 support verifying from SEM and BET results.And the content of oxygen functional groups was increased after oxidation modification,also motivating SA stabiliza-tion by hydrogen bond interaction in XPS analysis.FTIR results proved there is no chemical reaction happened between SA and CSC.Moreover,the latent heat and phase transition temperature of the as-prepared SA/CSC 15 composite are 76.69 J g^(−1)and 52.52℃,respectively.All composites exhibit excellent thermal stability under a working temperature of 180℃and form stability during phase change.Thermal energy storage-release test within 70℃presents the composite has fast heat transfer efficiency than pure SA.The composite filled in TSWH system has 0.75 W m^(−1)K^(−1)thermal conductivity which is 2.88 times higher than that of pure SA(0.26 W m^(−1)K−1).Besides,the TSWH system with a flow rate of 0.004 kg s^(−1)could heat water effectively after sunset and the energy obtained from the thermal storage system within 1830 s testing times is about 0.15 kW h.In all,SA/CSC composite with good physical-thermo properties has potential in thermal energy storage application,especially in solar energy storage. | Baoshan Xie Chuanchang Li Bo Zhang Lixin Yang Guiyu Xiao Jian Chen | 2020 | Energy and Built Environment2020，1，2： | 1 |

| 10 | MobiGemini:Sensitive-Based Data and Resource Protection Framework for Mobile Device显示文摘With the popularity of smartphones and the rapid development of mobile internet, smartphone becomes an important tool that store sensitive data of owner. Encryption naturally becomes a necessary means of protection. In certain situations, this is inadequate, as user may be coerced to hand over decryption keys or passwords of sensitive APP(Ali Pay) on mobile device. Therefore, only encryption cannot protect sensitive APP and privacy data stored on user's smartphone. To address these obstacles, we design a protection system called Mobi Gemini. It enables automatic uninstalling service that can immediately uninstall multiple APP at same time, and also enabling plausibly deniable encryption(PDE) on mobile devices by hiding encrypted volume within random data in free space of cache partition. We improve the key store way of previous PDE schemes on mobile device. The evaluation results show that the scheme introduces a few overhead compared with original android system enabling full disk encryption. | Shuangxi Hong Chuanchang Liu Bo Cheng Bingfei Ren Junliang Chen | 2017 | China Communications2017，14，7： | 1 |

| 12 | Emerging low-density polyethylene/paraffin wax/aluminum composite as a form-stable phase change thermal interface material显示文摘Thermal interface materials(TIMs) play a vital role in the thermal management of electronic devices and can significantly reduce thermal contact resistance(TCR). The TCR between the solid–liquid contact surface is much smaller than that of the solid–solid contact surface, but conventional solid–liquid phase change materials are likely to cause serious leakage. Therefore, this work has prepared a new formstable phase change thermal interface material. Through the melt blending of paraffin wax(PW) and low-density polyethylene(LDPE), the stability is improved and it has an excellent coating effect on PW. The addition of aluminum(Al) powder improves the low thermal conductivity of PW/LDPE, and the addition of 15wt% Al powder improves the thermal conductivity of the internal structure of the matrix by 67%. In addition, the influence of the addition of Al powder on the internal structure, thermal properties, and phase change behavior of the PW/LDPE matrix was systematically studied. The results confirmed that the addition of Al powder improved the thermal conductivity of the material without a significant impact on other properties, and the thermal conductivity increased with the increase of Al addition. Therefore, morphologically stable PW/LDPE/Al is an important development direction for TIMs. | Chuanchang Li Weixuan Wang Xiaoliang Zeng Chunxuan Liu Rong Sun | 2023 | International Journal of Minerals,Metallurgy and Materials2023，30，4： | 1 |

| 19 | Enhanced properties of stone coal-based composite phase change materials for thermal energy storage显示文摘Phase change materials (PCMs) can be incorporated with low-cost minerals to synthesize composites for thermal energy storage in building applications.Stone coal (SC) after vanadium extraction treatment shows potential for secondary utilization in composite preparation.We prepared SC-based composite PCMs with SC as a matrix,stearic acid (SA) as a PCM,and expanded graphite (EG) as an additive.The combined roasting and acid leaching treatment of raw SC was conducted to understand the effect of vanadium extraction on promoting loading capacity.Results showed that the combined treatment of roasting at 900℃ and leaching increased the SC loading of the composite by 6.2%by improving the specific surface area.The loading capacity and thermal conductivity of the composite obviously increased by 127%and 48.19%,respectively,due to the contribution of 3wt% EG.These data were supported by the high load of 66.69%and thermal conductivity of 0.59 W·m^(-1)·K-1of the designed composite.The obtained composite exhibited a phase change temperature of 52.17℃,melting latent heat of 121.5 J·g^(-1),and good chemical compatibility.The SC-based composite has prospects in building applications exploiting the secondary utilization of minerals. | Baoshan Xie Huan Ma Chuanchang Li Jian Chen | 2024 | International Journal of Minerals,Metallurgy and Materials2024，31，1： | 0 |
| 20 | System Energy and Efficiency Analysis of 12.5 W VRFB with Different Flow Rates显示文摘Vanadium redox flow battery(VRFB)is considered one of the most potential large-scale energy storage technolo-gies in the future,and its electrolyte flow rate is an important factor affecting the performance of VRFB.To study the effect of electrolyte flow rate on the performance of VRFB,the hydrodynamic model is established and a VRFB system is developed.The results show that under constant current density,with the increase of electrolyte flow rate,not only the coulombic efficiency,energy efficiency,and voltage efficiency will increase,but also the capacity and energy discharged by VRFB will also increase.But on the other hand,as the flow rate increases,the power of the pump also increases,resulting in a decrease in system efficiency.The energy discharged by the system does not increase with the increase in flow rate.Considering the balance between efficiency and pump power loss,it is experimentally proved that 120 mL·min-1 is the optimal working flow rate of the VRFB system,which can maximize the battery performance and discharge more energy. | Kehuan Xie Longhai Yu Chuanchang Li | 2023 | Energy Engineering2023，120，12： | 0 |
