| 1 | Integration of preparation of K,Na-embedded activated carbon and reduction of Zn-bearing dusts显示文摘Large amounts of solid wastes and flue gases are generated in iron and steel production process,probably leading to serious environmental pollution without duly handle.An innovative and green process of simultaneous reduction of zinc-bearing dusts and activation of low-rank coal was developed and its mechanism was clarified in this paper.Under the optimal conditions,the reduced zinc-bearing dusts containing low harmful elements(0.02%Zn,0.015%K and 0.03%Na)could be made as high-quality burden for blast furnace while the low-rank coal was transferred into K,Na-embedded activated carbon,which can be used as effective adsorbent for purification of SO_(2) and NO-containing flue gases.The solid wastes were successfully utilized to treat the flue gases through the process.The synergetic activation and reduction mechanism in the process was revealed.The coupling effect between reduction reactions of metal oxides in the dusts and activation reaction of carbon in the coal promoted the simultaneous reduction and activation process.In the meanwhile,part of the potassium and sodium from the zinc-bearing dusts could be adsorbed by the activated carbon and played a catalytic role in the activation process. | Dingzheng Wang Deqing Zhu Jian Pan Zhengqi Guo Congcong Yang Hongyu Tian Yuxiao Xue | 2022 | International Journal of Mining Science and Technology2022，32，3： | 1 |
| 2 | Mixed Aleatory-epistemic Uncertainty Modeling of Wind Power Forecast Errors in Operation Reliability Evaluation of Power Systems显示文摘As the share of wind power in power systems continues to increase, the limited predictability of wind power generation brings serious potential risks to power system reliability. Previous research works have generally described the uncertainty of wind power forecast errors(WPFEs) based on normal distribution or other standard distribution models, which only characterize the aleatory uncertainty. In fact, epistemic uncertainty in WPFE modeling due to limited data and knowledge should also be addressed. This paper proposes a multi-source information fusion method(MSIFM) to quantify WPFEs when considering both aleatory and epistemic uncertainties. An extended focal element(EFE) selection method based on the adequacy of historical data is developed to consider the characteristics of WPFEs. Two supplementary expert information sources are modeled to improve the accuracy in the case of insufficient historical data. An operation reliability evaluation technique is also developed considering the proposed WPFE model. Finally,a double-layer Monte Carlo simulation method is introduced to generate a time-series output of the wind power. The effectiveness and accuracy of the proposed MSIFM are demonstrated through simulation results. | Jinfeng Ding Kaigui Xie Bo Hu Changzheng Shao Tao Niu Chunyan Li Congcong Pan | 2022 | Journal of Modern Power Systems and Clean Energy2022，10，5： | 1 |
| 3 | A complete assembly of the rice Nipponbare reference genome显示文摘Dear Editor,In 2005,the current commonly used rice reference genome(Oryza sativa ssp.japonica cv.Nipponbare)was initially released by the International Rice Genome Sequencing Project(International Rice Genome Sequencing Project,2005).Thereafter,the reference genome was further updated in 2013 with improved genome assembly(IRGSP-1.0)and gene annotations(MSU7,RAP-DB)(Kawahara et al.,2013;Sakai et al.,2013).In the past 10 years,this reference has been serving as one of the most important genetic resources for subsequent rice functional genomics efforts.As several rice genomes had been assembled into gapless chromosomes with only 2–5 telomeres absent(Li et al.,2021;Song et al.,2021;Zhang et al.,2022),the IRGSP1.0 and its annotations still performed as the most widely used reference.However,limitations of sequencing technology and intricate genomic organization led to an under-representation of complex regions in this reference,leaving a total of 72 major gaps(including 19 telomeres),167 minor gaps,and 779 unknown bases(Kawahara et al.,2013),with an estimated length of3%of the genome unsolved. | Lianguang Shang Wenchuang He Tianyi Wang Yingxue Yang Qiang Xu Xianjia Zhao Longbo Yang Hong Zhang Xiaoxia Li Yang Lv Wu Chen Shuo Cao Xianmeng Wang Bin Zhang Xiangpei Liu Xiaoman Yu Huiying He Hua Wei Yue Leng Chuanlin Shi Mingliang Guo Zhipeng Zhang Bintao Zhang Qiaoling Yuan Hongge Qian Xinglan Cao Yan Cui Qianqian Zhang Xiaofan Dai Congcong Liu Longbiao Guo Yongfeng Zhou Xiaoming Zheng Jue Ruan Zhukuan Cheng Weihua Pan Qian Qian | 2023 | Molecular Plant2023，16，8： | 1 |

| 5 | Effect mechanism of aluminum occurrence and content on the induration characteristics of iron ore pellets显示文摘With the intensified depletion of high-grade iron ores,the increased aluminum content in iron ore concentrates has become unavoidable,which is detrimental to the pelletization process.Therefore,the effect mechanism of aluminum on pellet quality must be identified.In this study,the influence of aluminum occurrence and content on the induration of hematite(H)and magnetite(M)pellets was investigated through the addition of corresponding Al-containing additives,including alumina,alumogoethite,gibbsite,and kaolinite.Systematic mineralogical analysis,combined with the thermodynamic properties of different aluminum occurrences and the quantitative characterization of consolidation behaviors,were conducted to determine the related mechanism.The results showed that the alumina from various aluminum occurrences adversely affected the induration characteristics of pellets,especially at an aluminum content of more than 2.0wt%.The thermal decomposition of gibbsite and kaolinite tends to generate internal stress and fine cracks,which hinder the respective microcrystalline bonding and recrystallization between Fe2O3particles.The adverse effect on the induration characteristics of fired pellets with different aluminum occurrences can be relieved to varying degrees through the formation of liquid phase bonds between the hematite particles.Kaolinite is more beneficial to the induration process than the other three aluminum occurrences because of the formation of more liquid phase,which improves pellet consolidation.The research results can further provide insights into the effect of aluminum occurrence and content in iron ore concentrates on downstream processing and serve as a guide for the utilization of high-alumina iron ore concentrates in pelletization. | Hongyu Tian Deqing Zhu Jian Pan Congcong Yang Weiqun Huang Mansheng Chu | 2023 | International Journal of Minerals,Metallurgy and Materials2023，30，12： | 0 |
| 6 | Wetting sub-nanochannels via ionic hydration effect for improving charging dynamics显示文摘The ionic transport in sub-nanochannels plays a key role in energy storage,yet suffers from a high energy barrier.Wetting sub-nanochannels is crucial to accelerate ionic transport,but the introduction of water is challenging because of the hydrophobic extreme confinement.We propose wetting the channels by the exothermic hydration process of pre-intercalated ions,the effect of which varies distinctly with different ionic hydration structures and energies.Compared to the failed pre-intercalation of SO_(4)^(2-),HSO_(4)^(-) with weak hydration energy results in a marginal effect on the HOMO(Highest Occupied Molecular Orbital)level of water to avoid water splitting during the electrochemical intercalation.Meanwhile,the ability of water introduction is reserved by the initial incomplete dissociation state of HSO_(4)^(-),so the consequent exothermic reionization and hydration processes of the intercalated HSO_(4)^(-) promote the water introduction into sub-nanochannels,finally forming the stable confined water through hydrogen bonding with functional groups.The wetted channels exhibit a significantly enhanced ionic diffusion coef-ficient by~9.4 times. | Yayun Shi Xiaoli Zhao Qihang Liu Zhenghui Pan Congcong Liu Shanyi Zhu Zhijun Zuo Xiaowei Yang | 2024 | Green Energy & Environment2024，9，3： | 0 |
| 7 | Overview of epigenetic degraders based on PROTAC, molecular glue, and hydrophobic tagging technologies显示文摘Epigenetic pathways play a critical role in the initiation, progression, and metastasis of cancer. Over the past few decades, significant progress has been made in the development of targeted epigenetic modulators(e.g., inhibitors). However, epigenetic inhibitors have faced multiple challenges,including limited clinical efficacy, toxicities, lack of subtype selectivity, and drug resistance. As a result,the design of new epigenetic modulators(e.g., degraders) such as PROTACs, molecular glue, and hydrophobic tagging(Hy T) degraders has garnered significant attention from both academia and pharmaceutical industry, and numerous epigenetic degraders have been discovered in the past decade. In this review,we aim to provide an in-depth illustration of new degrading strategies(2017-2023) targeting epigenetic proteins for cancer therapy, focusing on the rational design, pharmacodynamics, pharmacokinetics, clinical status, and crystal structure information of these degraders. Importantly, we also provide deep insights into the potential challenges and corresponding remedies of this approach to drug design and development. Overall, we hope this review will offer a better mechanistic understanding and serve as a useful guide for the development of emerging epigenetic-targeting degraders. | Xiaopeng Peng Zhihao Hu Limei Zeng Meizhu Zhang Congcong Xu Benyan Lu Chengpeng Tao Weiming Chen Wen Hou Kui Cheng Huichang Bi Wanyi Pan Jianjun Chen | 2024 | Acta Pharmaceutica Sinica B2024，14，2： | 0 |

| 11 | Current situation of carbon emissions and countermeasures in China's ironmaking industry显示文摘The iron and steel industry(ISI) involves high energy consumption and high pollution. ISI in China, a leading country in the ISI,consumed 15% of the country’s total energy and produced more than 50% of the global ISI’s carbon emissions. Therefore, in the context of global low-carbon economy and emission reduction requirements, low-carbon smelting technology in the ISI has attracted increasingly more attention in China. This review summarizes the current status of carbon emissions and energy consumption in China’s ISI and discusses the development status and prospects of low-carbon ironmaking technology. The main route to effectively reducing carbon emissions is to develop a gas-based direct reduction process and replace sintering with pelletizing, both of which focus on developing pelletizing technology. However,the challenge of pelletizing process development is to obtain high-quality iron concentrates. Consequently, the present paper also summarizes the development status of China’s mineral processing technology, including fine-grained mineral processing technology, magnetization roasting technology, and flotation collector application. This paper aims to provide a theoretical basis for the low-carbon development of China’s ISI in terms of a dressing–smelting combination. | Chenmei Tang Zhengqi Guo Jian Pan Deqing Zhu Siwei Li Congcong Yang Hongyu Tian | 2023 | International Journal of Minerals,Metallurgy and Materials2023，30，9： | 0 |
