| 1 | Metal-Free C_(3)N_(4) with plentiful nitrogen vacancy and increased specific surface area for electrocatalytic nitrogen reduction显示文摘As a substitute for synthetic ammonia under mild condition, electrocatalytic nitrogen reduction reaction(NRR) provides a hopeful approach for the development of ammonia. Nevertheless, the current development of NRR electrocatalysts is far from enough and a systematic research is needed to gain a better improvement. This article presents that 2 D C_(3)N_(4)-NV with a large specific surface area and abundant nitrogen vacancies is prepared by a simple and feasible method, and used as a metal-free catalyst for electrocatalytic NRR. Experiment result and density functional theory(DFT) calculation reveal that nitrogen vacancies in 2 D C_(3)N_(4)-NV can act as an efficient active site for catalytic NRR, which is conducive to capturing and activating N_(2), lowering Gibbs free energy(DG) in reaction and inhibiting hydrogen evolution reaction(HER) at the same time. In addition, the larger specific surface area also makes more active site exposed, which is good for the contact between the electrolyte and the active site, thus enhancing its NRR activity. The electrocatalyst shows an excellent catalytic activity for NRR in 0.1 M HCl, including Faradaic efficiency of 10.96%, NH_(3) yields of 17.85 lg h^(-1) mg_(cat)^(-1)., and good stability(over 20 h). | Ziming Zhao Yu Long Sha Luo Yutong Luo Ming Chen Jiantai Ma | 2021 | Journal of Energy Chemistry2021，30，9： | 5 |
| 2 | Three-Dimensional Conformal Radiotherapy for Rectal Cancer and the Changes in Cancer Multi-biomarkers显示文摘OBJECTIVE To investigate the clinical efficacy of three-dimensional conformal radiotherapy(3D-CRT)for local y advanced or postoperatively relapsed rectal cancer,and to examine the changes in cancer multi-biomarkers. METHODS Sixty patients with locally advanced or postoperatively relapsed rectal cancer were randomly divided into two groups after 40 Gy external radiation,namely a late-course 3D-CRT group and a conventional radiotherapy group that served as the control.There were 30 patients in each group.For patients in the 3D-CRT group,multi-biomarkers were measured before and after radiotherapy and after relapse. RESULTS Response rates in the 3D-CRT and the control groups were 86.7%(26/30)and 70%(21/30)respectively,without a significant difference (P>0.05).The 1-,2-and 3-year survival rates were 80%,53.3%and 36.7% in the 3D-CRT group;in the control group the rates were 56.7%,40%and 13.3%respectively,with a significant difference(P=0.0213).CEA,CA19-9, CA242 and FER decreased after radiotherapy in the 3D-CRT group,P<0.01, indicating a significant difference.The values after relapse were higher than those without relapse,P<0.01,indicating a significant difference. CONCLUSION Conventional radiotherapy with a 3D-CRT boost gives better therapeutic effect to patients with locally advanced or postoperatively local y relapsed rectal cancer.A multi-biomarker protein chip diagnosis system can be utilized as an effective tool to determine the therapeutic effect and prognosis. | Rui Wei Yangde Zhang Jiantai He Liangfang Shen Jidong Hong Haijun Wu | 2007 | Chinese Journal of Clinical Oncology2007，4，6： | 2 |

| 10 | Nitrogen-doped carbon nanotubes by multistep pyrolysis process as a promising anode material for lithium ion hybrid capacitors显示文摘Lithium-ion hybrid capacitors(LIHCs) is a promising electrochemical energy storage devices which combines the advantages of lithium-ion batteries and capacitors.Herein,we developed a facile multistep pyrolysis method,prepared an amorphous structure and a high-level N-doping carbon nanotubes(NCNTs),and by removing the Co catalyst,opening the port of NCNTs,and using NCNTs as anode material.It is shows good performance due to the electrolyte ions enter into the electrode materials and facilitate the charge transfer.Furthermore,we employ the porous carbon material(APDC) as the cathode to couple with anodes of NCNTs,building a LIHCs,it shows a high energy density of 173 Wh/kg at 200 W/kg and still retains 53 Wh/kg at a high power density of 10 kW/kg within the voltage window of 0-4.0 V,as well as outstanding cyclic life keep 80% capacity after 5000 cycles.This work provides an opportunity for the preparation of NCNTs,that is as a promising high-performance anode for LIHCs. | Juan Yang Dan Xu Ruilin Hou Junwei Lang Zhaoli Wang Zhengping Dong Jiantai Ma | 2020 | Chinese Chemical Letters2020，31，9： | 0 |
| 11 | Constructing vertical phase separation of polymer blends via mixed solvents to enhance their photovoltaic performance显示文摘A polymer blend comprising poly(3-hexylthiophene)(P3HT)donor and poly[2,7-(9,9′-octyl-fluorene)-alt-5,5-(4′,7′-di-2-thienyl-5′,6′-bis(hexyloxy)-2′,1′,3′-benzothiadiazole)](PFDTBT-OC6)acceptor is used as the active layer to fabricate all-polymer solar cells.The blend morphology variance processed with pure and mixed solvents,and the related photovoltaic performance,are investigated in detail.It is found that,due to its low surface energy,a thin P3HT enrichment layer on the top surface of the active layer greatly increases bimolecular recombination and results in S-kinks of the illuminated current density-voltage curves.With the incorporation of p-xylene(a marginal solvent of P3HT)in the blend solution,the P3HT enrichment atop the active layer surface is effectively decreased because the high boiling-point p-xylene suppresses the diffusion of P3HT chains toward the top surface during the film-drying process.The bimolecular recombination was thus improved and the S-kinks of the photovoltaic curves were completely removed.The overall power conversion efficiencies of the devices are strongly boosted(from 0.88%to 1.41%)when chlorobenzene:p-xylene mixed solvent is used to replace pure chlorobenzene. | Qingqing Yang Jiantai Wang Xiaoqin Zhang Jun Zhang Yingying Fu Zhiyuan Xie | 2015 | Science China Chemistry2015，58，2： | 0 |
| 12 | Large-scale programmable assembly of functional microcomponents for advanced electronics via light-regulated adhesion and polymer growth显示文摘Large-area,programmable assembly of diverse micro-objects onto arbitrary substrates is a fundamental yet challenging task.Herein a simple wafer-level micro-assembly technique based on the light-triggered change in both surface topography and interfacial adhesion of a soft photo-sensitive polymer is proposed.In particular,the light-regulated polymer growth creates locally indented and elevated zones on the stamp surface.The light-mediated adhesion reduction,on the other hand,facilitates the inks to be released from the polymer.The interplay of these two effects makes it feasible for the programmable assembly of ultra-small components onto various substrates coated with supplementary adhesive layers.The fidelity of this technique is validated by assembling diverse materials and functional devices,with the printing size up to 4-inch.This work provides a rational strategy for large-scale and programmable assembly of diverse delicate micro-objects,bypassing the common issues of some existing techniques such as poor transfer uniformity,small printing area,and high cost. | Chan Guo Zhangxu Pan Changhao Li Shenghan Zou Chao Pang Jiantai Wang Jinhua Hu Zheng Gong | 2022 | npj Flexible Electronics2022，6，1： | 0 |
