| 1 | Monolithic three-dimensional integration of aligned carbon nanotube transistors for high-performance integrated circuits显示文摘Carbon nanotube field-effect transistors(CNT FETs)have been demonstrated to exhibit high performance only through low-temperature fabrication process and require a low thermal budget to construct monolithic three-dimensional(M3D)integrated circuits(ICs),which have been considered a promising tech-nology to meet the demands of high-bandwidth computing and fully func-tional integration.However,the lack of high-quality CNT materials at the upper layer and a low-parasitic interlayer dielectric(ILD)makes the reported M3D CNT FETs and ICs unable to provide the predicted high performance.In this work,we demonstrate a multilayer stackable process for M3D integration of high-performance aligned carbon nanotube(A-CNT)transistors and ICs.A low-κ(-3)interlayer SiO_(2)layer is prepared from spin-on-glass(SOG)through processes with a highest temperature of 220℃,presenting low parasitic capaci-tance between two transistor layers and excellent planarization to offer an ideal surface for the A-CNT and device fabrication process.A high-quality A-CNT film with a carrier mobility of 650 cm 2 V^(-1)s^(-1)is prepared on the ILD layer through a clean transfer process,enabling the upper CNT FETs fabri-cated with a low-temperature process to exhibit high on-state current(1 mAμm^(-1))and peak transconductance(0.98 mSμm^(-1)).The bottom A-CNT FETs maintain pristine high performance after undergoing the ILD growth and upper FET fabrication.As a result,5-stage ring oscillators utilizing the M3D architecture show a gate propagation delay of 17 ps and an active region of approximately 100μm 2,representing the fastest and the most compact M3D ICs to date. | Chenwei Fan Xiaohan Cheng Lin Xu Maguang Zhu Sujuan Ding Chuanhong Jin Yunong Xie Lian-Mao Peng Zhiyong Zhang | 2023 | InfoMat2023，5，7： | 0 |
| 2 | Nano-additive manufacturing of multilevel strengthened aluminum matrix composites显示文摘Nanostructured materials are being actively developed,while it remains an open question how to rapidly scale them up to bulk engineering materials for broad industrial applications.This study propose an industrial approach to rapidly fabricate high-strength large-size nanostructured metal matrix composites and attempts to investigate and optimize the deposition process and strengthening mechanism.Here,advanced nanocrystalline aluminum matrix composites(nanoAMCs)were assembled for the first time by a novel nano-additive manufacturing method that was guided by numerical simulations(i.e.the in-flight particle model and the porefree deposition model).The present nanoAMC with a mean grain size<50 nm in matrix exhibited hardness eight times higher than the bulk aluminum and shows the highest hardness among all Al–Al2O3 composites reported to date in the literature,which are the outcome of controlling multiscale strengthening mechanisms from tailoring solution atoms,dislocations,grain boundaries,precipitates,and externally introduced reinforcing particles.The present high-throughput strategy and method can be extended to design and architect advanced coatings or bulk materials in a highly efficient(synthesizing a nanostructured bulk with dimensions of 50×20×4 mm^(3) in 9 min)and highly flexible(regulating the gradient microstructures in bulk)way,which is conducive to industrial production and application. | Chenwei Shao Haoyang Li Yankun Zhu Peng Li Haoyang Yu Zhefeng Zhang Herbert Gleiter AndréMcDonald James Hogan | 2023 | International Journal of Extreme Manufacturing2023，5，1： | 0 |
| 3 | LncRNA MIR205HG expression predicts efficacy of neoadjuvant chemotherapy for patients with locally advanced breast cancer显示文摘To the Editor,Recent studies reported that lncRNA MIR205HG expression is associated with sensitivity to anti-epidermal growth factor receptor(EGFR)drug in lung cancer cells.However,few clinical studies reported the role of this molecule in breast cancer,particularly in the neoadjuvant setting.In this study,we explored the clinical significance of MIR205HG expression with its predictive and prognostic value for patients with locally advanced breast cancer. | Yaqian Xu Chenwei Yuan Jing Peng Liheng Zhou Yanping Lin Yaohui Wang Jie Zhang Jiayi Ma Wenjin Yin Jinsong Lu | 2022 | Genes & Diseases2022，9，4： | 0 |
| 4 | Development and characterization of mycelium bio-composites by utilization of different agricultural residual byproducts显示文摘Mycelium bio-composites was developed by incubating Pleurotus ostreatus fungi on different sub-strates from agricultural residual byproducts,including rice straw,bagasse,coir-pith,sawdust,and corn straw.The scanning electron microscope(SEM)results showed that the hypha of com-posite derived from bagasse was the densest,and the diameter of hypha was the biggest(0.77μm),which was presumably due to the existence of cellulose in bagasse in the form of dextran and xylan.The maximum and minimum compression strength for sawdust substrate and corn straw substrate were 456.70 and 270.31 kPa,respectively.The flexural strength for bagasse sub-strate and rice straw substrate were 0.54 and 0.16 MPa,respectively.The two composites derived from rice straw and bagasse exhibited higher hydrophobic properties than others.In comparison,mycelium bio-composite derived from bagasse showed the best comprehensive properties.Except for a little worse anti-creep ability and waterproof performance,other properties of mycelium bio-composites could be comparable to commercially expanded polystyrene(EPS)packaging mate-rial.Derived from this study,mycelium material provided a good way to use agricultural residual byproducts and could be a good alternative to non-biodegradable materials for packaging appli-cations. | Liucheng Peng Jing Yi Xinyu Yang Jing Xie Chenwei Chen | 2023 | Journal of Bioresources and Bioproducts2023，8，1： | 0 |
| 5 | Decarbonization path of China’s public building sector from bottom to top显示文摘The building sector is one of the three major energy consumption areas and one of the main areas responsible for carbon emissions.In 2019,carbon emissions related to construction and building operations in China accounted for 38% of the total social carbon emissions,of which construction accounted for 16% and operations accounted for 22%.Due to its large volume and high energy consumption per unit area,public buildings account for 38% of the operating energy consumption of all buildings,that is,8% of the total national energy consumption.At this time,the building industry must take decarbonization actions to avoid a delay in realizing carbon neutrality and an emission peak.We need to form a unified process for the implementation boundary,implementation path,and index system to build a zero-carbon implementation plan for China’s public building sector.Based on bottom-up practical cases,this paper proposes the KAYA model,which is applicable to different scales and different types of public buildings/communities,and proposes specific and feasible plans.Through the implementation of demand reduction,energy efficiency improvement,and the fully-use of renewable energy in all five clear steps,this paper promotes the implementation of decarbonization in China’s building industry. | Chenwei Peng Qingpeng Wei Wengang Wei | 2022 | Carbon Neutrality2022，1，1： | 0 |
