| 1 | Cretaceous source rocks and associated oil and gas resources in the world and China: A review显示文摘The Cretaceous is one of the most important stratigraphic intervals for hydrocarbon source rocks. This article summarizes the distribution, formation, and development characteristics of Cretaceous source rocks and associated oil and gas resources in the world and China, aiming at improving the understanding of this hydrocarbon enrichment and at broadening domestic exploration. Outside China, these rocks are generally formed in marine or transgressive environments during both the Upper and Lower Cretaceous. The majority of Cretaceous source rocks are located in the Persian Gulf, Mediterranean, and Gulf Coast of the USA. Kerogen types within these source rocks have distinct spatial distribution characteristics, with high-latitude Boreal Realm, Tethyan Realm and South Gondwana Realm source rocks containing type III, II, II-III kerogens, respectively. Cretaceous source rocks in China can be mainly divided into four zones: Eastern, Central, Northwest, and Qinghai–Tibet Plateau zones. The majority of Chinese source rocks formed in the Early Cretaceous, whereas the most productive source rocks are developed in the Upper Cretaceous, such as those within the Songliao Basin. Most of these basins are formed in lacustrine environments, although some may have been influenced by transgressive events. Cretaceous source rocks are formed in four distinctive ways: 1) during Oceanic Anoxic Events and associated global sea-level rises, 2) in Black Sea–type retention basins, 3) during transgression and 4) during periods of significant terrestrial input. Formation of these source rocks is controlled by four factors: paleoclimate, paleotopography, transgression, and Oceanic Anoxic Events. These four major controlling factors indicate that China's hydrocarbon exploration within the Cretaceous should focus on two key areas with extremely low exploration levels, the Qinghai–Tibet Plateau and the southeastern coast of China. | Yang Ruofei Wang Yuce Cao Jian | 2014 | Petroleum Science2014，11，3： | 5 |
| 2 | Removal of nitric oxide from simulated flue gas via denitrification in a hollow-fiber membrane bioreactor显示文摘A hollow-fiber membrane bioreactor(HMBR) was studied for its ability to treat nitric oxide(NO) from simulated flue gas. The HMBR was operated for 9 months and showed a maximum elimination capacity of 702 mg NO/(m2·day) with a removal efciency of 86%(gas residence time of 30 sec, inlet NO concentration of 2680 mg/m3, pH 8). Varying operation parameters were tested to determine the stability and response of the HMBR. Both the inlet NO concentration and gas residence time influenced the removal of NO in the HMBR. NO elimination capacity increased with an increase in inlet NO concentration or a shortening of gas residence time. Higher removal efciency of NO was obtained at a longer gas residence time or a lower inlet NO concentration. Microbial communities of the HMBR were sensitive to the variation in pH value and alkalescence corresponding to an optimum pH value of 8. In addition, NO elimination capacity and removal efciency were inversely proportional to the inlet oxygen concentration. Sulfur dioxide had no great influence on elimination capacity and removal efciency of NO. Product analysis was performed to study N2O and N2 production and confirmed that the majority of the microorganisms were denitrifying bacteria in the HMBR. Compared to other bioreactors treating NO, this study showed that the denitrifying HMBR was a good option for the removal of NO. | Xinyu Zhang Ruofei Jin Guangfei Liu Xiyang Dong Jiti Zhou Aijie Wang | 2013 | Journal of Environmental Sciences2013，25，11： | 5 |
| 3 | Spectral decomposition method for predicting magmatic intrusion into a coal bed显示文摘Accurate prediction of magmatic intrusion into a coal bed is illustrated using the method of seismic spectral decomposition.The characteristics of coal seismic reflections are first analyzed and the effect of variable time windows and domain frequencies on the spectral decomposition are examined.The higher domain frequency of coal bed reflections using the narrower STFT time window,or the smaller ST scale factor,are acceptable.When magmatic rock intrudes from the bottom of the coal bed the domain frequency of the reflections is decreased slightly,the frequency bandwidth is narrowed correspondingly,and the response from spectral decomposition is significantly reduced.Intrusion by a very thin magmatic rock gives a spectral decomposition response that is just slightly less than what is seen from a normal coal bed.Results from an actual mining area were used to validate the method.Predicting the boundary of magmatic intrusions with the method discussed herein was highly accurate and has been validated by observations from underground mining. | Wang Xin Chen Tongjun Cui Ruofei Xu Yongzhong | 2012 | International Journal of Mining Science and Technology2012，22，4： | 3 |
| 4 | External-force-driven solution epitaxy of large-area 2D organic single crystals for high-performance field-effect transistors显示文摘Growth of two-dimensional(2D)organic single crystals(2DOSCs)on water surface has attracted increasing attention,because it can serve as a molecularly flat and defect-free substrate.However,large-area growth of 2DOSCs with controllable crystal orientation on water surface remains a key challenge.Herein,we develop a simple method,i.e.external-force-driven solution epitaxy(EFDSE),for the large-area growth of 2DOSCs at air/water interface.Using 2,7-didecylbenzothienobenzothiophene(C1o-BTBT)as an example,high-quality 2D C10-BTBT crystals on centimeter scale are generated by directionally controlling the spreading of organic solution on water surface with external force.Benefiting from the controllable crystal orientation with optimal charge transport,the corresponding 2DOSC-based organic field-effect transistors(OFETs)exhibit a high carrier mobility of 13.5 cm^2·V^-1·s^-1(effective mobility=5.4 cm^2·V^-1·s^-1 according to a reliability factor of 40%),which represents the best result achieved for water-surface-assembled 2DOSC based OFETs.Furthermore,by transterring the C1o-BTBT 2DOSCs to flexible substrates,devices with excellent bending stability are achieved.It is anticipated that our method will provide new insight into the controllable growth of large-area 2DOSCs for high-performance organic devices. | Jinwen Wang Wei Deng Wei Wang Ruofei Jia Xiuzhen Xu Yanling Xiao Xiujuan Zhang Jiansheng Jie Xiaohong Zhang | 2019 | Nano Research2019，12，11： | 3 |
| 5 | Refined spatial temporal epigenomic profiling reveals intrinsic connection between PRDM9-mediated H3K4me3 and the fate of double-stranded breaks显示文摘Meiotic recombination is initiated by the formation of double-strand breaks(DSBs),which are repaired as either crossovers(COs)or noncrossovers(NCOs).In most mammals,PRDM9-mediated H3K4me3 controls the nonrandom distribution of DSBs;however,both the timing and mechanism of DSB fate control remain largely undetermined.Here,we generated comprehensive epigenomic profiles of synchronized mouse spermatogenic cells during meiotic prophase I,revealing spatiotemporal and functional relationships between epigenetic factors and meiotic recombination.We find that PRDM9-mediated H3K4me3 at DSB hotspots,coinciding with H3K27ac and H3K36me3,is intimately connected with the fate of the DSB.Our data suggest that the fate decision is likely made at the time of DSB formation:earlier formed DSBs occupy more open chromatins and are much more competent to proceed to a CO fate.Our work highlights an intrinsic connection between PRDM9-mediated H3K4me3 and the fate decision of DSBs,and provides new insight into the control of CO homeostasis. | Yao Chen Ruitu Lyu Bowen Rong Yuxuan Zheng Zhen Lin Ruofei Dai Xi Zhang Nannan Xie Siqing Wang Fuchou Tang Fei Lan Ming-Han Tong | 2020 | Cell Research2020，30，3： | 3 |

| 7 | Sustained release of hydrogen sulfide from anisotropic ferrofluid hydrogel for the repair of spinal cord injury显示文摘Spinal cord injury(SCI)results in massive neuronal death,axonal disruption,and cascading inflammatory response,which causes further damage to impaired neurons.The survived neurons with damaged function fail to form effective neuronal circuits.It is mainly caused by the neuroinflammatory microenvironment at injury sites and regenerated axons without guidance.To address this challenge,a ferrofluid hydrogel(FFH)was prepared with Ferric tetrasulfide(Fe3S4),carboxymethyl chitosan,and gold.Its internal structural particles can be oriented in a magnetic field to acquire anisotropy.Moreover,Fe3S4 can release hydrogen sulfide(H2S)with anti-inflammatory effects under acidic conditions.Regarding in vitro experiments,0.01g/ml Fe3S4 FFH significantly reduced the inflammatory factors produced by LPS-induced BV2 cells.Oriented and longer axons of the induced neural stem cells loaded on anisotropic FFH were observed.In vivo experiments showed that FFH reduced the activated microglia/macrophage and the expression of pro-inflammatory factors in SCI rats through the NF-κB pathway.Moreover,it significantly promoted directional axonal regrowth and functional recovery after SCI.Given the critical role of inhibition of neuroinflammation and directional axonal growth,anisotropic Fe3S4 FFH is a promising alternative for the treatment of SCI. | Ruofei Wang Xia-Xiao Wu Zhenming Tian Tian Hu Chaoyang Cai Guan-Ping Wu Gang-Biao Jiang Bin Liu | 2023 | Bioactive Materials2023，，5： | 1 |
| 8 | Effects of Dispersive Agent and Alumina Micropowder on Workability of Al_2O_3-MgO Castables for Steel Ladles显示文摘This work aims at enhancing the workability of Al2 O3-Mg O castables. Al2 O3-Mg O castables were prepared using tabular alumina particles( 5-3,3-1,≤1 mm),tabular alumina fines( ≤0. 088 mm),fused magnesia( ≤1 mm),reactive alumina micropowder( PFR40,PBR,and CL) and calcined alumina micropowder( AC34 B5 and CT) as the main starting materials,calcium aluminate cement( Secar71) as the binder,and polycarboxylic acid water reducer WS,FS,and AD as the dispersive agent,respectively. Effects of three dispersive agents addition( 0. 4 mass% WS,0. 2 mass% FS and 1 mass% AD),two kinds of reactive alumina micropowder addition( PFR40 and PBR),composite alumina micropowder addition( PFR40-AC34 B5 and CL-CT,the mass ratio from 9/0 to 3/6)on the flow value,apparent porosity,bulk density,cold crushing strength and cold modulus of rupture of Al2 O3-MgO castables were investigated. The results show that:( 1) with PBR or PFR40,the castables with0. 4 mass% WS own better performance than those with0. 2 mass% FS or 1 mass% AD;( 2) compared with the castables with CL-CT composite powder, the castables with PFR40-AC34 B5 composite powder have slightly higher flow value; with the decreasing ratio of PFR40 and AC34 B5,or the decreasing ratio of CL andCT,the castables have declined flow value and the dried castable specimens have decreased density but the mildly changed strength; in consideration of the high price of reactive alumina,a proper compositing ratio shall be selected. | WANG Qingheng LI Yuanbing WEI Hao XU Nana LI Shujing LUO Han XIANG Ruofei | 2018 | China's Refractories2018，27，3： | 0 |

| 10 | DNMT3A reads and connects histone H3K36me2 to DNA methylation显示文摘Dear Editor,DNA methylation at the 5-position of cytosine(5mC)is a crucial epigenetic mark in regulating biological processes including gene silencing,gene imprinting,and X chromo-some inactivation(Jaenisch and Bird,2003;Smith and Meissner,2013).Human genome encodes three DNA methyltransferases,DNMT1,DNMT3A and DNMT3B to catalyze 5mC.Although not tightly restricted,DNMT1 is thought to maintain the established pattern of 5mC throughout DNA replication,while DNMT3A and DNMT3B are largely responsible for the de novo establishment of 5mC.It has long been questioned how de novo DNA 5mC patterns are established in different genomic regions and whether histone modifications crosstalk to the process.Until recently,it was reported that through recognition of histone H3K36me3 mark,DNMT3B plays a dominant role in medi-ating DNA 5mC in the genic region undergoing active tran-scription(Baubec et al.,2015;Neri et al,2017).However,5mC occurs at both intergenic and genic regions,while H3K36me3 is largely absent in the intergenic regions,indi-cating that the intergenic 5mC may be mediated through diferent mechanisms. | Wenqi Xu Jiahui Li Bowen Rong Bin Zhao Mei Wang Ruofei Dai Qilong Chen Hang Liu Zhongkai Gu Shuxian Liu Rui Guo Hongjie Shen Feizhen Wu Fei Lan | 2020 | Protein & Cell2020，11，2： | 0 |
| 11 | Correction to:DNMT3A reads and connects histone H3K36me2 to DNA methylation显示文摘The author would like to add the below information in this correction.A similar study from Chao Lu group was published online on 5 September 2019 in Nature,entitled“The histone mark H3K36me2 recruits DNMT3A and shapes the intergenic DNA methylation landscape”(Weinberg et al.,2019).Although both studies reported the preferential recognition of H3K36me2 by DNMT3A PWWP,ours in addition uncovered a stimulation function by such interaction on the activity of DNMT3A.On the disease connections,we used a NSD2 gain-of-function model which led to the discovery of potential therapeutic implication of DNA inhibitors in the related cancers,while the other study only used NSD1 and DNMT3A loss-of-function models. | Wenqi Xu Jiahui Li Bowen Rong Bin Zhao Mei Wang Ruofei Dai Qilong Chen Hang Liu Zhongkai Gu Shuxian Liu Rui Guo Hongjie Shen Feizhen Wu Fei Lan | 2020 | Protein & Cell2020，11，3： | 0 |
| 12 | Textured Asymmetric Membrane Electrode Assemblies of Piezoelectric Phosphorene and Ti_(3)C_(2)T_(x)MXene Heterostructures for Enhanced Electrochemical Stability and Kinetics in LIBs显示文摘Black phosphorus with a superior theoretical capacity(2596 mAh g^(-1))and high conductivity is regarded as one of the powerful candidates for lithium-ion battery(LIB)anode materials,whereas the severe volume expansion and sluggish kinetics still impede its applications in LIBs.By contrast,the exfoliated two-dimensional phosphorene owns negligible volume variation,and its intrinsic piezoelectricity is considered to be beneficial to the Li-ion transfer kinetics,while its positive influence has not been discussed yet.Herein,a phosphorene/MXene heterostructure-textured nanopiezocomposite is proposed with even phosphorene distribution and enhanced piezo-electrochemical coupling as an applicable free-standing asymmetric membrane electrode beyond the skin effect for enhanced Li-ion storage.The experimental and simulation analysis reveals that the embedded phosphorene nanosheets not only provide abundant active sites for Li-ions,but also endow the nanocomposite with favorable piezoelectricity,thus promoting the Li-ion transfer kinetics by generating the piezoelectric field serving as an extra accelerator.By waltzing with the MXene framework,the optimized electrode exhibits enhanced kinetics and stability,achieving stable cycling performances for 1,000 cycles at 2 A g^(-1),and delivering a high reversible capacity of 524 m Ah g^(-1)at-20℃,indicating the positive influence of the structural merits of self-assembled nanopiezocomposites on promoting stability and kinetics. | Yihui Li Juan Xie Ruofei Wang Shugang Min Zewen Xu Yangjian Ding Pengcheng Su Xingmin Zhang Liyu Wei Jing‑Feng Li Zhaoqiang Chu Jingyu Sun Cheng Huang | 2024 | Nano-Micro Letters2024，16，4： | 0 |
| 13 | SETDB1-mediated CD147-K71 di-methylation promotes cell apoptosis in non-small cell lung cancer显示文摘Protein post-translational modifications(PTMs)are at the heart status of cellular signaling events and broadly involved in tumor progression.CD147 is a tumor biomarker with various PTMs,promoting tumor metastasis and metabolism reprogramming.Nevertheless,the relationship between the PTMs of CD147 and apoptosis has not been reported.In our study,we produced a specific anti-CD147-K71 di-methylation(CD147-K71me2)antibody by immunizing with a di-methylated peptide and observed that the level of CD147-K71me2 in non-small cell lung cancer(NSCLC)tissues were lower than that in NSCLC adjacent tissues.SETDB1 was identified as the methyltransferase catalyzing CD147 to generate CD147-K71me2.RNA-seq showed that FOSB was the most significant differentially expressed gene(DEG)between wild-type CD147(CD147-WT)and K71-mutant CD147(CD147-K71R)groups.Subsequently,we found that CD147-K71me2 promoted the expression of FOSB by enhancing the phosphorylation of p38,leading to tumor cell apoptosis.In vivo experiments showed that CD147-K71me2 significantly inhibited tumor progression by promoting cell apoptosis.Taken together,our findings indicate the inhibitory role of CD147-K71me2 in tumor progression from the perspective of post-translational modification,which is distinct from the pro-cancer function of CD147 itself,broadening our perspective on tumor-associated antigen CD147. | Ming-Yan Shi Yarong Wang Ying Shi Ruofei Tian Xiaohong Chen Hai Zhang Ke Wang Zhinan Chen Ruo Chen | 2024 | Genes & Diseases2024，11，2： | 0 |
