| 1 | 3D N,O-Codoped Egg-Box-Like Carbons with Tuned Channels for High Areal Capacitance Supercapacitors显示文摘Functional carbonaceous materials for supercapacitors(SCs)without using acid for post-treatment remain a substantial challenge.In this paper,we present a less harmful strategy for preparing three-dimensional(3D)N,O-codoped egg-box-like carbons(EBCs).The as-prepared EBCs with opened pores provide plentiful channels for ion fast transport,ensure the e ective contact of EBCs electrodes and electrolytes,and enhance the electron conduction.The nitrogen and oxygen atoms doped in EBCs improve the surface wettability of EBC electrodes and provide the pseudocapacitance.Consequently,the EBCs display a prominent areal capacitance of 39.8μF cm-2(340 F g-1)at 0.106 m A cm-2 in 6 M KOH electrolyte.The EBC-based symmetric SC manifests a high areal capacitance to 27.6μF cm-2(236 F g-1)at 0.1075 m A cm-2,a good rate capability of 18.8μF cm-2(160 F g-1)at 215 m A cm-2 and a long-term cycle stability with only 1.9%decay after 50,000 cycles in aqueous electrolyte.Impressively,even in all-solid-state SC,EBC electrode shows a high areal capacitance of 25.0μF cm-2(214 F g-1)and energy density of 0.0233 m Wh cm-2.This work provides an acid-free process to prepare electrode materials from industrial by-products for advanced energy storage devices. | Feng Wei Xiaojun He Lianbo Ma Hanfang Zhang Nan Xiao Jieshan Qiu | 2020 | Nano-Micro Letters2020，12，7： | 13 |
| 2 | Efficacy of platinum in advanced triple-negative breast cancer with germline BRCA mutation determined by next generation sequencing显示文摘Objective:To compare the efficacy of platinum-and non-platinum-based regimens as first-line treatment for advanced triple-negative breast cancer(TNBC)and analyze the relationship between their efficacy and BRCA gene status.Methods:Retrospectively analyze clinical data of 220 patients diagnosed pathologically with advanced TNBC and treated at the Department of Breast Oncology,Peking University Cancer Hospital from 2013 to 2018 and evaluate the efficacy of chemotherapy.A total of 114 patients had BRCA1/2 gene tested by next generation sequencing(NGS)using peripheral blood,and we analyzed the correlation between their efficacy and BRCA1/2 gene status.Results:Non-platinum-based chemotherapy(NPCT)was administered to 129 and platinum-based chemotherapy(PBCT)to 91 study patients.The clinical benefit rate(CBR)and median progression-free survival(PFS)were not statistically different between NPCT and PBCT groups.The median overall survival(OS)was 30.0 and 22.5 months for PBCT and NPCT group,respectively[P=0.090,hazard ratios(HR)=0.703].BRCA status was assessed in 114 patients,14 of whom had deleterious germline BRCA1/2(g BRCA)mutations(seven in each group).In PBCT group,the CBR was 85.7%and 35.1%for patients with and without deleterious g BRCA mutations,respectively(P=0.039).The median PFS were 14.9 and 5.3 months and median OS were 26.5 and 15.5 months for patients with and without deleterious g BRCA mutations,respectively(P=0.001,P=0.161,respectively).Patients in PBCT group had significantly greater rates of grade 3-4 anemia(5.5%vs.0%)and thrombocytopenia(8.8%vs.0%),whereas palmar-plantar erythrodysesthesia(12.4%vs.0%)and peripheral neuropathy(8.6%vs.1.1%)occurred more frequently in NPCT group.Conclusions:Platinum-based regimens are more effective in patients with deleterious g BRCA mutations,but no difference in patients without BRCA gene mutations,so non-platinum is an option in patients without BRCA gene mutations considering the toxicity and side effect.And we recommend that patients with advanced TNBC should have BRCA gene test. | Nan Wang Kun Li Wenfa Huang Weiyao Kong Xiaoran Liu Weijie Shi Feng Xie Hanfang Jiang Guohong Song Lijun Di Quanren Wang Jianjun Yu Huiping Li | 2020 | Chinese Journal of Cancer Research2020，32，2： | 7 |
| 3 | Impact Assessment and Protection of Outstanding Landscape Integrity in a Natural Heritage Site:Fairy Valley,Kanas Nature Reserve,Xinjiang,China显示文摘The essential purpose of the Convention Concerning the Protection of World Cultural and Natural Heritage is to protect the integrity of heritage values.Outstanding landscape is the core embodiment of the aesthetic value of a natural heritage site.This paper proposes a new assessment method from the point of view of the protection of heritage values.It is used to measure the degree of outstanding landscape integrity under the human and natural impact in natural heritage sites.This paper employ three indices,a visual index of outstanding landscape,a harmony index of the artificial landscape and a disturbance index of damaged landscape,to measure the impact of landscape integrity.The impact assessment model is based on a weighted combination of the three indices.The study site is the Fairy Valley,Kanas Nature Reserve,Xinjiang Uygur Autonomous Region in northwest China.The information employed is derived from field investigation and a Digital Elevation Model(DEM).A comprehensive evaluation of the Fairy valley was undertaken and it was determined that the outstanding landscape values are being compromised.Three protection methods are proposed to reduce the adverse effects and maintain landscape quality,thereby providing site managers with suggestions for the protection of natural heritage values.More broadly,the paper contributes novel methods of landscape assessment applicable to natural protected areas. | HANFang YANG Zhaoping LIU Xinyu DI Feng | 2011 | Journal of Mountain Science2011，8，1： | 4 |
| 4 | Ultra-robust stretchable electrode for e-skin:In situ assembly using a nanofiber scaffold and liquid metal to mimic water-to-net interaction显示文摘The development of stretchable electronics could enhance novel interface structures to solve the stretchability-conductivity dilemma,which remains a major challenge.Herein,we report a nano-liquid metal(LM)-based highly robust stretchable electrode(NHSE)with a self-adaptable interface that mimics water-tonet interaction.Based on the in situ assembly of electrospun elastic nanofiber scaffolds and electrosprayed LM nanoparticles,the NHSE exhibits an extremely low sheet resistance of 52 mΩsq^(-1).It is not only insensitive to a large degree of mechanical stretching(i.e.,350%electrical resistance change upon 570%elongation)but also immune to cyclic deformation(i.e.,5%electrical resistance increases after 330000 stretching cycles with 100%elongation).These key properties are far superior to those of the state-of-the-art reports.Its robustness and stability are verified under diverse circumstances,including long-term exposure to air(420 days),cyclic submersion(30000 times),and resilience against mechanical damages.The combination of conductivity,stretchability,and durability makes the NHSE a promising conductor/electrode solution for flexible/stretchable electronics for applications such as wearable on-body physiological signal detection,human-machine interaction,and heating e-skin. | Jinwei Cao Fei Liang Huayang Li Xin Li Youjun Fan Chao Hu Jing Yu Jin Xu Yiming Yin Fali Li Dan Xu Hanfang Feng Huali Yang Yiwei Liu Xiaodong Chen Guang Zhu Run-Wei Li | 2022 | InfoMat2022，4，4： | 1 |
| 5 | High sensitivity and broad linearity range pressure sensor based on hierarchical in-situ filling porous structure显示文摘Flexible piezoresistive pressure sensor with high sensitivity over a broad linearity range have been attracting tremendous attention for its applications in health monitoring,artificial intelligence,and human-machine interfaces.Herein,we report a hierarchical insitu filling porous piezoresistive sensor(HPPS)by direct ink writing(DIW)printing and curing of carbon nanofibers(CNFs)/polydimethylsiloxane(PDMS)emulsion.Hierarchical geometry significantly increases the contact area,distributes stress to multilayered lattice and internal porous structure,resulting in a broad sensing range.Moreover,unlike conventional hollow porous structure,the CNFs networks in-situ filling porous structure generates more contact sites and conductive pathways during compression,thereby achieving high sensitivity and linearity over entire sensing range.Therefore,the optimized HPPS achieves high sensitivity(4.7 kPa^(−1))and linearity(coefficient of determination,R^(2)=0.998)over a broad range(0.03-1000 kPa),together with remarkable response time and repeatability.Furthermore,the applications in diverse pressure scenarios and healthcare monitoring are demonstrated. | Jin Xu Huayang Li Yiming Yin Xin Li Jinwei Cao Hanfang Feng Wandi Bao Hao Tan Fanyuan Xiao Guang Zhu | 2022 | npj Flexible Electronics2022，6，1： | 0 |
