| 1 | Progress in flexible organic thin-film transistors and integrated circuits显示文摘Organic thin-film transistor constructs the headstone of flexible electronic world such as conformable sensor arrays and flexible active-matrix displays. With solutionprocessed methods, it forges ahead toward large-area, lowcost manufacturing goals. As an indispensable complement to traditional silicon-based transistors, organic thin-film field-effect transistors have made great progress in materials,performance, bending capacity, and integrated circuits in recent few years. Flexible transistors and circuitry have extremely promising application prospects and possess irreplaceable status in foldable displays, artificial skins and bendable smart cards. In this review, we will discuss the evolution of flexible organic transistors and integrated circuits in terms of material, fabrication as well as application. | Congyan Lu Zhuoyu Ji Guangwei Xu Wei Wang Lingfei Wang Zhiheng Han Ling Li Ming Liu | 2016 | Science Bulletin2016，61，14： | 5 |

| 3 | Surface nanostructures orienting self-protection of an orthodontic nickel-titanium shape memory alloys wire显示文摘Shape memory alloys (SMA) have been applied to a wide variety of applications in a number of different fields such as aeronautical applications, sensors/actuators, medical sciences as well as orthodontics. It is a hot topic to enhance the anti-corrosion ability of orthodontic wires for clinical applications. In this letter, a very nice fractal structure, micro-domains with identical nanometer sized grooves, was ob- tained on the surfaces of the orthodontic wires with an oxygen plasma and acid corrosion. The concave parts of the grooves were dominated by titanium and convex parts were the same as the bulk wires. The micro-nano fractal structure generated a hydrophobic surface with the largest contact angle to water being about 157°. The titanium dominated nanolayer and the hydrophobicity of the surface resulted in jointly the great improvement of the anti-corrosion ability of the orthodontic wires. Because the fractal structures of the wires were formed automatically when they immersed in acidic environment, hence, the self-protection of the oxygen plasma-treated orthodontic wires in acidic environment indicates their potential applications in orthodontics, and should be also inspirable for other applications of SMA materials. | NIE Qiong JI ZhuoYu LIN JiuXiang HU WenPing | 2007 | Chinese Science Bulletin2007，52，21： | 4 |
| 4 | Low voltage organic devices and circuits with aluminum oxide thin film dielectric layer显示文摘Low voltage operating organic devices and circuits have been realized using atomic layer deposition deposited aluminum oxide thin film as dielectric layer. The dielectric film has per unit area capacitance of 165 nF/cm2 and leakage current of 1 nA/cm2 at 1 MV/cm. The devices and circuits use the small-molecule hydrocarbon pentacene as the active semiconductor material. Transistors,inverters,and ring oscillators with operating voltage lower than 5 V were obtained. The mobility of organic field-effect transistors was extracted to be 0.16 cm2/Vs in saturation range,the threshold voltage is 0.3 V,and the on/off current ratio is larger than 105. The gain of inverters is estimated to be 12 at -5 V supply voltage,and the propagation delay is 0.25 ms per stage in 5-stage ring oscillators. | SHANG LiWei JI ZhuoYu CHEN YingPin WANG Hong LIU Xin HAN MaiXin LIU Ming | 2011 | Science China(Technological Sciences)2011，54，1： | 2 |
| 5 | Rapid and selective uranium extraction from aqueous solution under visible light in the absence of solid photocatalyst显示文摘Extraction of uranium from radioactive waste-water is of significant importance for environmental protection and the recovery of uranium resource.Different from the previous reports to use the solid absorbent/photocatalyst for U(VI)removal,herein,we proposed a new eco-friendly method for the rapid and selective extraction of uranium from aqueous solutions under visible light without solid materials.At optimal pH value and in the presence of organics like alcohols,the U(VI)could be extracted efficiently to form brown uranium solid over wide uranium concentrations under anaerobic condition and visible light,by utilizing the excitation of the given U(VI)species.With comprehensive modelling of the electronic ultraviolet-visible(UV-Vis)properties,it is proved that pH adjusting towards U(VI)could induce efficient ligand-to-metal-charge-transfer(LMCT)within the uranyl complex under visible light and the reduction of U(VI)to form U(V),which can be transformed into U(IV)via disproportionation reaction.The resulting U(IV)in solid phase makes the extraction much more convenient in operation.More importantly,the excellent selectivity for uranium extraction over interfering alkali metal ions,transition metal ions and the lanthanide metal ions shows a powerful application potential. | Shaojun Li Yezi Hu Zewen Shen Yawen Cai Zhuoyu Ji Xiaoli Tan Zhixin Liu Guixia Zhao Shuxian Hu Xiangke Wang | 2021 | Science China Chemistry2021，64，8： | 2 |
