| 1 | Superhydrophobic self-extinguishing cotton fabrics for electromagnetic interference shielding and human motion detection显示文摘Multifunctional intelligent fire-safe cotton fabric promises next-generation fire-fighting uniform and sen-sor applications.However,cotton fabrics’hygroscopicity and intrinsic flammability significantly impede their potential applications in industries.Herein,we report a superhydrophobic fireproof cotton fabric(PEI-APP-PEI-MXene)generated via sequential layer-by-layer deposition of polyethyleneimine(PEI),am-monium polyphosphate(APP),and titanium carbide(MXene),followed by hydrophobic treatment with silicone elastomer.Compared to untreated cotton,the treated cotton fabric with 10 polymolecular layers exhibits∼43%and∼42%reductions in the peak heat release rate and total heat release,respectively,a desired UL-94 V-0 rating,and a high limiting oxygen index(LOI)value of 39.5 vol.%.In addition to that,the treated fabrics displayed improved electromagnetic interference(EMI)shielding and motion-sensing abilities.The presented work provides a facile and effective surface modification approach to generate multifunctional cotton fabrics with promising practical applications. | Lei Liu Zhewen Ma Menghe Zhu Lina Liu Jinfeng Dai Yongqian Shi Jiefeng Gao Toan Dinh Thanh Nguyen Long-Cheng Tang Pingan Song | 2023 | Journal of Materials Science & Technology2023，，1： | 2 |
| 2 | Adaptive evolution of rbcL in Reaumuria soon garica(Tamaricaceae)显示文摘In the field of phylogenetic analyses, the rbc L gene encoded large subunit Ribulose-1,5-biphosphate carboxylase/oxygenase(Rubisco, EC4.1.1.39), which plays a crucial role in the process of photosynthesis for most terrestrial plants, has been considered to be conserved; however, recent controversy regarding rbc L conservation has appeared since it was proposed to be under natural selection within all principal lineages of land plants. In this study, by examining the variation of DNA and protein sequences among 17 species in the family Tamaricaceae, three nonsynonymous mutations were identified to be under positive selection. The favored sites were located in the alph-helix domains of Rubisco, with decreased hydrophobicity and increased entropy, which could facilitate CO2 penetration into the active site of Rubisco. We also found that the expression level of rbc L in different genotypes of Reaumuria soongarica shifted in response to various stresses such as drought, temperature, salt, and light. This study not only sheds light on the functional/structural features of Rubisco in the evolution scenarios from C3-like into C4 in Tamaricaceae but also provides useful information on directing genetic performance to enhance photosynthesis efficiency of desert plants for sustaining fragile desert ecosystems; furthermore, it promotes the ability to cope with desert aridification and global warming. | ChaoJu Qian MengHe Gu HengXia Yin Yong Shi ChengLiang Yin Xia Yan XiaoFei Ma | 2017 | Research in Cold and Arid Regions2017，9，1： | 1 |
| 3 | Optimization of Gas-Flooding Fracturing Development in Ultra-Low Permeability Reservoirs显示文摘Ultra-low permeability reservoirs are characterized by small pore throats and poor physical properties, which areat the root of well-known problems related to injection and production. In this study, a gas injection floodingapproach is analyzed in the framework of numerical simulations. In particular, the sequence and timing of fracturechanneling and the related impact on production are considered for horizontal wells with different fracturemorphologies. Useful data and information are provided about the regulation of gas channeling and possible strategiesto delay gas channeling and optimize the gas injection volume and fracture parameters. It is shown that inorder to mitigate gas channeling and ensure high production, fracture length on the sides can be controlled andlonger fractures can be created in the middle by which full gas flooding is obtained at the fracture location in themiddle of the horizontal well. A Differential Evolution (DE) algorithm is provided by which the gas injectionvolume and the fracture parameters of gas injection flooding can be optimized. It is shown that an improvedoil recovery factor as high as 6% can be obtained. | Lifeng Liu Menghe Shi Jianhui Wang Wendong Wang Yuliang Su Xinyu Zhuang | 2024 | Fluid Dynamics & Materials Processing2024，20，3： | 0 |
