| 1 | 界面键合作用有效增强NiSe@Fe_(2)O_(3)的水氧化本征活性和稳定性显示文摘析氧反应(OER)电催化剂的本征活性及稳定性主要取决于活性材料的表界面性能.本文采用两步水热法制备了一种新型核壳异质结构电催化剂(NF/NiSe@Fe_(2)O_(3)).该催化剂在1 mol L^(-1)的KOH介质中,电流密度为10或200 mA cm^(-2)时,析氧反应过电位分别低至220和282 mV,同时还具有较小的Tafel斜率(36.9 mV dec^(-1))及良好的长期稳定性(~230h).X射线光电子能谱和X射线吸收光谱表明,NF/NiSe@Fe_(2)O_(3)异质结构一方面具有高度羟基化的表面,同时由于在NiSe和Fe_(2)O_(3)的界面处形成Fe-Se键而具有较强的界面耦合作用.密度泛函理论计算进一步证实,Fe-Se键的形成导致了NiSe@Fe_(2)O_(3)异质结d带中心的移动并很好地优化了其电子结构,从而促进了析氧反应过程中含氧中间体的吸附及O_(2)的脱附,极大增强了催化剂的OER活性.另外,其独特的核壳结构及较强的界面耦合作用有效提升了催化剂的长期稳定性.该研究为界面键合效应对电催化剂OER性能的影响提供了一些基本认识. | 郭凯璐 王彦涛 杨思卓 黄俊峰 邹泽华 潘海瑞 Pravin S.Shinde 潘善林 黄吉儿 徐彩玲 | 2021 | Science Bulletin2021，66，1： | 3 |
| 2 | Cycle Time Reduction in Injection Molding by Using Milled Groove Conformal Cooling显示文摘This paper presents simulation study on Milled Grooved conformal cooling channels(MGCCC)in injection molding.MGCCC has a more effective cooling surface area which helps to provide efficient cooling as compared to conventional cooling.A case study of Encloser part is investigated for cycle time reduction and quality improvement.The performance designs of straight drilled are compared with MGCCC by using Autodesk Moldflow Insight(AMI)2016.The results show total 32.1% reduction of cooling time and 9.86% reduction of warpage in case of MGCCC as compared to conventional cooling. | Mahesh S.Shinde Kishor M.Ashtankar | 2017 | Computers, Materials & Continua2017，，3： | 1 |
| 3 | Supramolecular Polymer Intertwined Free-Standing Bifunctional Membrane Catalysts for All-Temperature Flexible Zn-Air Batteries显示文摘Rational construction of flexible free-standing electrocatalysts featuring long-lasting durability,high efficiency,and wide temperature tolerance under harsh practical operations are fundamentally significant for commercial zinc-air batteries.Here,3D flexible free-standing bifunctional membrane electrocatalysts composed of covalently cross-linked supramolecular polymer networks with nitrogen-deficient carbon nitride nanotubes are fabricated(referred to as PEMAC@NDCN)by a facile self-templated approach.PEMAC@NDCN demonstrates the lowest reversible oxygen bifunctional activity of 0.61 V with exceptional long-lasting durability,which outperforms those of commercial Pt/C and RuO_(2).Theoretical calculations and control experi-ments reveal the boosted electron transfer,electrolyte mass/ion transports,and abundant active surface site preferences.Moreover,the constructed alkaline Zn-air battery with PEMAC@NDCN air-cathode reveals superb power density,capacity,and discharge-charge cycling stability(over 2160 cycles)compared to the reference Pt/C+RuO_(2).Solid-state Zn-air batteries enable a high power density of 211 mW cm^(−2),energy density of 1056 Wh kg^(−1),stable charge-discharge cycling of 2580 cycles for 50 mA cm^(−2),and wide temperature tolerance from−40 to 70℃with retention of 86%capacity compared to room-temperature counterparts,illustrating prospects over harsh operations. | Nayantara K.Wagh Sambhaji S.Shinde Chi Ho Lee Sung-Hae Kim Dong-Hyung Kim Han-Don Um Sang Uck Lee Jung-Ho Lee | 2022 | Nano-Micro Letters2022，14，11： | 0 |
| 4 | Effect of Different Shapes of Conformal Cooling Channel on the Parameters of Injection Molding显示文摘Cooling system improvement is important in injection molding to get betterquality and productivity. The aim of this paper was to compare the different shapes of theconformal cooling channels (CCC) with constant surface area and CCC with constantvolume in injection molding using Mold-flow Insight 2016 software. Also the CCC resultswere compared with conventional cooling channels. Four different shapes of the CCC suchas circular, elliptical, rectangular and semi-circular were proposed. The locations of thecooling channels were also kept constant. The results in terms of cooling time, cycle timereduction and improvement in quality of the product shows that no significant effect ofCCC’s shapes when surface area of CCC kept constant. On the other hand, the rectangularCCC shows better result as compared to other shapes of CCC when volume of CCC werekept constant. | Mahesh S.Shinde Kishor M.Ashtankar | 2018 | Computers, Materials & Continua2018，，3： | 0 |
| 5 | 喷丝头形状对聚酯长丝性能的影响显示文摘纤维截面形状对聚酯(PET)长丝结构和性能的影响可通过在相同纺丝条件下选用不同形状喷丝头制备聚酯预取向丝进行研究。纤维之间的唯一区别是所采用喷丝头的横截面形状。试验选择了不同的截面形状,包括圆形、中空、三叶形、八叶形和三角形。特殊形状的喷丝头所制得的纤维被用于地毯或家用纺织品等不同用途,圆形截面纤维则被用于牛仔布的生产。纤维截面形状的差异主要受其模量、高应变、屈服应力和沸水收缩的影响,还未确定是否对纤维结晶度和高应力产生影响。结果发现:圆形截面的350/96聚酯预取向丝在各阶段均表现出较好的性能。 | R.Turukmane S.Shinde S.Gulhane K.K.Gupta 宋清泉(译) 于俊荣(校) | 2022 | 国际纺织导报2022，50，7： | 0 |
