| 1 | Properties of Steel Slag and Stainless Steel Slag as Cement Replacement Materials:A Comparative Study显示文摘To enhance the understanding about the utilization of steel slags as a cementitious material, we comparatively studied the chemical, mineralogical and morphological properties of two types of steel slag; basicoxygen-furnace carbon slag(BOF C) and electric-arc-furnace stainless steel slag(EAF S). Moreover, we studied the standard consistency, setting time and the effect of the slag replacement ratios on the fluidity and compressive strength of blended cement mortar. The experimental results showed that BOF C had higher alkalinity, higher pH value and more hydraulic phases than EAF S. Both types of slag showed water reduction effect due to its high fineness. Neat BOF C paste showed flash set and acceleration in the initial setting time of blended cement especially at high slag proportions. However, EAF S prolonged the setting time of blended cement even at low slag proportions. The pH values for blended cement contained 50% BOF C or EAF S were lower than those of pure cement paste. Despite of slag type, compressive strength gradually decreased with increasing slags content. The strength of BOF C mortar was higher than that of EAF S mortar with the same replacement ratio for the same age. Slag activity index demonstrated that BOF C and EAF S conformed to the Chinese National Standard(GB/T 20491-2006) requirements for steel slag as grade one and grade two, respectively. | SALY Fathy GUO Liping MA Rui GU Chunping SUN Wei | 2018 | Journal of Wuhan University of Technology(Materials Science)2018,33,6: | 5 |
| 2 | Accelerated design and characterization of non-uniform cellular materials via a machine-learning based framework显示文摘Cellular materials,widely found in engineered and nature systems,are highly dependent on their geometric arrangement.A nonuniform arrangement could lead to a significant variation of mechanical properties while bringing challenges in material design.Here,this proof-of-concept study demonstrates a machine-learning based framework with the capability of accelerated characterization and pattern generation.Results showed that the proposed framework is capable of predicting the mechanical response curve of any given geometric pattern within the design domain under appropriate neural network architecture and parameters.Additionally,the framework is capable of generating matching geometric patterns for a targeted response through a databank constructed from our machine learning model.The accuracy of the predictions was verified with finite element simulations and the sources of errors were identified.Overall,our machine-learning based framework can boost the design efficiency of cellular materials at unit level,and open new avenues for the programmability of function at system level. | Chunping Ma Zhiwei Zhang Benjamin Luce Simon Pusateri Binglin Xie Mohammad H.Rafiei Nan Hu | 2020 | npj Computational Materials2020,,1: | 3 |

| 8 | Progress on rock mechanics research of Beishan granite for geological disposal of high-level radioactive waste in China显示文摘The mechanical behavior of host rock for a deep geological repository of high-level radioactive waste plays a key role in ensuring the isolation function of host rock as a natural barrier under the multi-field coupling environment.For a better understanding of granite in China's Beishan pre-selected area for geological disposal of high-level radioactive waste,a series of investigations were carried out on in-situ stress field of rock mass at depth,strength and deformation characteristics of rocks under different stress and temperature conditions,and rock boreability and adaptability to Tunnel Boring Machine(TBM)technology.The results indicate that Beishan granite shows typical characteristics as a hard and brittle rock with a quite low permeability,and it is favorable to geological disposal.Meanwhile,a new rock mass suitability evaluation system was proposed,and the rock mass mainly composed of Beishan granite was proven to be suitable for geological disposal.Besides,the constructability of Beishan granite at engineering scale was tested and verified through field tests in the Beishan Exploration Tunnel(BET).Here,we summarize the main outcomes of rock mechanics research on Beishan granite in the past years and introduced the current progress of Beishan underground research laboratory(URL)for geological disposal. | Liang Chen Xingguang Zhao Jian Liu Hongsu Ma Chunping Wang Haiyang Zhang Ju Wang | 2023 | Rock Mechanics Bulletin2023,2,3: | 1 |
| 9 | Effect of Yishen Qiqiao Fang on dopamine content in serum and cerebrospinal fluid of patients in persistent vegetative statec显示文摘BACKGROUND: It has been demonstrated that the attack of persistent vegetative state is associated with the damaged neuron, which produces dopamine, and nervous pathway, the reduce of dopamine or malfunction of dopamine. OBJECTIVE: To observe the effect of self-made traditional Chinese medicine (TCM) Yishen Qiqiao Fang, which has the functions of supplementing qi and nourishing blood, resolving phlegm by promoting blood circulation, restoring consciousness and inducing resuscitation, on the contents of dopamine in serum and cerebrospinal fluid of patients in persistent vegetative state. DESIGN: An open randomized controlled clinical trial. SETTINGS: Nanjing University of Traditional Chinese Medicine, Nanjing Zijin Hospital. PARTICIPANTS: Thirty-eight inpatients of persistent vegetative state were selected from the Department of Neurology, Nanjing Zijin Hospital from August 2005 to November 2006. The patients were diagnosed according to the diagnostic standards set by the summary of a meeting for specialists in Nanjing. Informed contents were obtained from their relatives. According to the order of admission, the enrolled patients were divided into control group (n =20) and TCM treated group (n =20). METHODS: In the control group, the patients were treated with routine treatments for the symptoms. In the TCM treated group, the patients were treated with Yishen Qiqiao Fang besides the same treatments in the control group. TCM dispensing granules: each bag of mongolian milkvetch root, Chinese angelica and peach seed equaled to 10 g crude drug respectively; each bag of grassleaf sweetflag rhizome and dahurian angelica root equaled to 6 g crude drug respectively; Musk 0.05 g. The daily dosage for adults: 4 bags of mongolian milkvetch root, 2 bags of Chinese angelica, 0.05 g musk, 1 bag of peach seed, 2 bags of grassleaf sweetflag rhizome and 2 bags of dahurian angelica root, which should be given though nasal feeding or gastrostogavage before breakfast and supper every day, the course lasted for 2 months. The contents of dopamine in serum and cerebrospinal fluid were determined with enzyme immunoassay analyzer before and after treatment in both groups. MAIN OUTCOME MEASURES: Contents of dopamine in serum and cerebrospinal fluid before and after treatment in both groups. RESULTS: Totally 38 patients of persistent vegetative state were enrolled, 33 of them were involved in the final analysis of results, and the other 5 missed. The contents of dopamine in serum and cerebrospinal fluid had no obvious differences between the two groups both before and after treatment (P > 0.05). In the control group, the contents of dopamine in serum and cerebrospinal fluid had no obvious differences before and after treatment (P > 0.05). In the TCM treated group, the contents of dopamine in serum and cerebrospinal fluid after treatment were obviously higher than those before treatment (t =2.174, 2.485, P < 0.05). CONCLUSION: Yishen Qiqiao Fang can significantly increase the contents of dopamine in serum and cerebrospinal fluid of patients in persistent vegetative state, which may be one of the mechanisms for ameliorating persistent vegetative state. | Guangkui Feng Tao Liu Zhaoqing Xi Fujun Lin Peidong Wang Lichun Zhang Chunping Wu Hulong Ma Chong Liu | 2007 | Neural Regeneration Research2007,2,7: | 1 |
| 10 | Construction of phosphorus-doping with spontaneously developed selenium vacancies: Inducing superior ion-diffusion kinetics in hollow Cu_(2)Se@C nanospheres for efficient sodium storage显示文摘Achieving high-efficiency sodium storage in metal selenides is still severely constrained in consideration of their inferior electronic conductivity and inadequate Na^(+)insertion pathways and active sites.Heteroatom doping accompanied by spontaneously developed lattice defects can effectively tune electronic structure of metal selenides,which give a strong effect to motivate fast charge transfer and Na^(+)accessibility.Herein,we finely designed and successfully constructed a fascinating phosphorus-doped Cu_(2)Se@C hollow nanosphere with abundant vacancy defects(Cu_(2)P_(x)Se_(1-x)@C)through a combination strategy of selenization of Cu_(2)O nanosphere template,self-polymerization of dopamine,and subsequent phosphorization treatment.Such exquisite composite possesses enriched active sites,superior conductivity,and sufficient Na^(+)insertion channel,which enable much faster Na^(+)diffusion rates and more remarkable pseudocapacitive features,Satisfyingly,the Cu_(2)P_(x)Se_(1-x)@C composites manifest the supernormal sodium-storage capabilities,that is,a reversible capacity of 403.7 mA h g^(-1) at 1.0 A g^(-1) over 100 cycles,and an ultrastable cyclic lifespan over 1000 cycles at 20.0 A g^(-1) with a high capacity-retention of about249.7 mA h g^(-1).The phase transformation of the Cu_(2)P_(x)Se_(1-x)@C involving the intercalation of Na^(+)into Cu_(2)Se and the following conversion of NaCuSe to Cu and Na2Se were further demonstrated through a series of ex-situ characterization methods.DFT results demonstrate that the coexistence of phosphorusdoping and vacancy defects within Cu_(2)Se results in the reduction of Na^(+)adsorption energy from-1.47to-1.56 eV improving the conductivity of Cu_(2)Se to further accelerate fast Na^(+)mobility. | Xiaoqing Ma Yadong Li Xiaojiang Long Hong-chuan Luo Chunping Xu Guangzhao Wang Wenxi Zhao | 2023 | Journal of Energy Chemistry2023,,2: | 0 |
| 11 | Electron structure and substituent effects in o-,m-,p-IC_6H_4OCH_3 iodoanisoles显示文摘The electronic structures and substituent effects in o-,m-,and p-iodoanisoles have been investigated by ultraviolet photoelectron spectroscopy(UPS).The observed UPS bands were analyzed by combining empirical arguments and theoretical methods.Owing to the electron-donating nature of both iodoand methoxy substituents,the first ionization potentials of the three iodoanisoles are lower than those of iodobenzene and anisole.The presence of the two substituents in iodoanisoles leads to an electronrich structure,which might contribute to the observed high reactivity of iodoanisoles in a number of organic reactions. | TONG ShengRui,WANG WeiGang,MA ChunPing,GE MaoFa & WANG DianXun Beijing National Laboratory for Molecular Sciences(BNLMS),State Key Laboratory for Structural Chemistry of Unstable and Stable Species,Institute of Chemistry,Chinese Academy of Sciences,Beijing 100190,China | 2009 | Science China Chemistry2009,52,11: | 0 |
| 12 | Long-term functional maintenance of primary hepatocytes in vitro using macroporous hydrogels engineered through liquid-liquid phase separation显示文摘Preserving the functionality of hepatocytes in vitro poses a significant challenge in liver tissue engineering and bioartificial liver,as these cells rapidly lose their metabolic and functional characteristics after isolation.Inspired by the macroporous structures found in native liver tissues,here we develop synthetic hydrogel scaffolds that closely mimic the liver’s structural organization through the phase separation between polyethylene glycol(PEG)and polysaccharides.Our hydrogels exhibit interconnected macroporous structures and appropriate mechanical properties,providing an optimal microenvironment conducive to hepatocyte adhesion and the formation of sizable aggregates.Compared to two-dimensional hepatocyte cultures,enhanced functionalities of hepatocytes cultured in our macroporous hydrogels were observed for 14 days,as evidenced by quantitative reverse-transcription–polymerase chain reactions(qRT-PCR),immunofluorescence,and enzyme linked immunosorbent assay(ELISA)analyses.Protein sequencing data further confirmed the establishment of cell–cell interactions among hepatocytes when cultured in our hydrogels.Notably,these hepatocytes maintained a protein expression lineage that closely resembled freshly isolated hepatocytes,particularly in the Notch and tumor necrosis factor(TNF)signaling pathways.These results suggest that the macroporous hydrogels are attractive scaffolds for liver tissue engineering. | Yang Sun Sheng Yin Jian Cui Zhongxia Wang Yueying Han Ding Ma Shuo Wang Junhua Wu Yi Cao Chunping Jiang Xiaosong Gu | 2024 | Nano Research2024,17,3: | 0 |

| 14 | Capturing semantic features to improve Chinese event detection显示文摘Current Chinese event detection methods commonly use word embedding to capture semantic representation,but these methods find it difficult to capture the dependence relationship between the trigger words and other words in the same sentence.Based on the simple evaluation,it is known that a dependency parser can effectively capture dependency relationships and improve the accuracy of event categorisation.This study proposes a novel architecture that models a hybrid representation to summarise semantic and structural information from both characters and words.This model can capture rich semantic features for the event detection task by incorporating the semantic representation generated from the dependency parser.The authors evaluate different models on kbp 2017 corpus.The experimental results show that the proposed method can significantly improve performance in Chinese event detection. | Xiaobo Ma Yongbin Liu Chunping Ouyang | 2022 | CAAI Transactions on Intelligence Technology2022,7,2: | 0 |
| 15 | Sulfation of the extracellular polysaccharide from the edible fungus Stropharia rugosoannulata with its antioxidant activity显示文摘An acidic extracellular polysaccharide(EPS)was gained from Stropharia rugosoannulata fermentation broth by the alcohol precipitate method.Sulfated derivative of EPS(S-EPS)was gained by chlorosulfonic acid-pyridine method and the conditions were as follows:pyridine as the reaction solvent,temperature 80°C,and reaction time 90 min.The chemical structure and chain conformation of EPS and S-EPS were characterized by FT-IR,NMR and size exclusion chromatography(SEC)coupled with multi-angle laser light scattering(MALLS)detection.FT-IR spectra indicated the sulfated group was linked to the polymer.The EPS mainly consists of mannose,glucose and glucuronic acid,and the glycosidic bond type is mainly(1→4)-linked and(1→6)-linked.C6 and C2 were substituted by sulfate groups.The EPS was degraded into smaller molecular weight(Mw)polysaccharides with the larger molecular size(Rg)after sulfation and S-EPS has better hydrophilicity.Moreover,the sulfated derivative S-EPS was found to have a better scavenging ability on hydroxyl radicals than EPS.It proved that the chemical modification of S.rugosoannulata polysaccharides by sulfation effectively enhanced their antioxidant activity. | Hui Hao Chun Cui Yuqing Xing Xuewei Jia Bingjie Ma Wenyi Kang Tianxiao Li Mingqi Gao Chunping Xu | 2023 | Journal of Future Foods2023,3,1: | 0 |
| 16 | Green synthesis of Chlorin e6 and tests of its photosensitive bactericidal activities显示文摘Phototoxic treatments of pathogenic bacteria and fungi of trees induce oxidative damage that is preferable to toxic chemical treatment.Here,we used green methods to synthesize Chlorin e6 from chlorophyll a,which was extracted from crude silkworm excrement using concentrated(strong)alkali hydrolysis and acidification.The photosensitive bactericidal activities of the new chlorin were tested in vitro,and possible mechanisms of action are discussed.The results showed that Chlorin e6 can be lightactivated to have bactericidal activity against Escherichia coli,Bacillus subtilis and Fusarium oxysporum,but it had little bactericidal effect in the dark.This kind of chlorin compounds has great potential as a natural phototoxic antimicrobial compound to control harmful bacteria on the leaves in forestry systems. | Guocai Zhang Jing Yang Chunping Hu Xiucheng Zhang Xiao Li Shan Gao Xiao Ouyang Ning Ma Hao Wei | 2019 | Journal of Forestry Research2019,30,6: | 0 |
