| 4 | INFLUENCE OF ORDINARY ACCELERATORS ON HYDRATION OF BELITE CEMENT显示文摘The study revealed that ordinary accelerators for Portland cement also improves early strength of Belite cement remarkably, but one serious defect exists which lead to a high strength reduction at the age of 28 days. The paper analyzes the action mechanism of ordinary accelerators on Belite cement. It shows that these accelerators can not accelerate the hydration of β-C2S directly. The reason that they can increase early strength of Belite cement is that they can promote hydration of C3A and C4AF, through which can make early hydration of β-C2S in clinker advanced relatively. The strength reduction at 28 day age is mainly because these accelerators restrain the further hydration of β-C2S at later age. Considering these results, we obtain basic requirements of ideal accelerators for Belite cement. | GUO Suihua FENG Peizhi ZENG Yimin LUO ShiyongChina Building Materials Academy Wuhan University of TechnologyUniversity of Technology and Science Beijing | 1999 | Journal of Wuhan University of Technology(Materials Science)1999，14，4： | 0 |
| 5 | Recent advances of amorphous-phase-engineered metal-based catalysts for boosted electrocatalysis显示文摘Amorphous metal-based catalysts(AMCs)have sparked intense research interests in the field of electrocatalysis elicited by their hallmark features such as unlimited volume and morphology,manipulated electronic structures,enriched defects,and unsaturated surface atom coordination.Nevertheless,the manipulation of the amorphous phase in metal-based catalysts is so far impractical,and thus their electrocatalytic mechanism yet remains ambiguous.In this review,the latest advances in AMCs are systematically reviewed,covering amorphous-phase engineering strategy,structure manipulation,and amorphization of various material categories for electrocatalysis.Specifically,a series of applications of AMCs in electrocatalysis for the oxygen reduction reaction(ORR),hydrogen evolution reaction(HER),and oxygen evolution reaction(OER)are summarized based on the classification criteria of substances.Finally,we put forward current challenges that have not yet been clarified in the field of AMCs,and propose possible solutions,particularly from the perspective of the evolution of electron microscopy.It is expected to promote the understanding of the amorphization-catalysis relationship and provide a guideline for designing high-performance electrocatalysts. | Jiakang Tian Yongqing Shen Peizhi Liu Haixia Zhang Bingshe Xu Yanhui Song Jianguo Liang Junjie Guo | 2022 | Journal of Materials Science & Technology2022，，32： | 0 |
| 6 | Stretchable alkenamides terminated Ti_(3)C_(2)T_(x)MXenes to release strain for lattice-stable mixed-halide perovskite solar cells with suppressed halide segregation显示文摘Bandgap-tunable mixed-halide perovskite materials have attracted considerable interest because of their indispensability as top counterparts in tandem solar cells.However,the soft and disordered lattice always suffers from severe phase segregation under illumination,which is particularly susceptible to residual lattice strain.Herein,we report a strain regulation strategy by using alkenamides terminated Ti_(3)C_(2)T_(x)MXenes as an additive into perovskite precursor.Apart from the role of a template for grain growth to obtain high-quality films,the stretchable alkyl chain promotes lattice shrinkage or expansion to form an elastic grain boundary to eliminate the spatially distributed stain and shut down ion migration channels.As a result,the all-inorganic perovskite solar cells based on CsPbIBr_(2)and CsPbI_(2)Br halides achieve prolonged device stability under harsh conditions and the best power conversion efficiencies up to 11.06%and 14.30%,respectively. | Xuemei Yao Jialong Duan Yuanyuan Zhao Junshuai Zhang Qiyao Guo Qiaoyu Zhang Xiya Yang Yanyan Duan Peizhi Yang Qunwei Tang | 2023 | Carbon Energy2023，5，12： | 0 |
| 7 | Monodispersed ultrathin twisty PdBi alloys nanowires assemblies with tensile strain enhance C_(2+)alcohols electrooxidation显示文摘Direct alcohol fuel cells(DAFCs)are powered by the alcohol electro-oxidation reaction(AOR),where an electrocatalyst with an optimal electronic structure can accelerate the sluggish AOR.Interestingly,strain engineering in hetero-catalysis offers a promising route to boost their catalytic activity.Herein,we report on a class of monodispersed ultrathin twisty PdBi alloy nanowires(TNWs)assemblies with face-centered structures that drive AORs.These thin nanowire structures expose a large number of reactive sites.Strikingly,Pd_(6)Bi_(1)TNWs show an excellent current density of 2066,3047,and 1231 mA mg_(Pd)^(-1)for oxidation of ethanol,ethylene glycol,and glycerol,respectively.The“volcano-like”behaviors observed on PdBi TNWs for AORs indicate that the maximum catalytic mass activity is a well balance between active intermediates and blocking species at the interface.This study offers an effective and universal method to build novel nanocatalysts in various applications by rationally designing highly efficient catalysts with specific strain. | Xianzhuo Lao Ze Li Likang Yang Ben Zhang Wanneng Ye Aiping Fu Peizhi Guo | 2023 | Journal of Energy Chemistry2023，，4： | 0 |
| 8 | Strenuous exercise-tolerance stretchable dry electrodes for continuous multi-channel electrophysiological monitoring显示文摘Electrophysiological monitoring under strenuous exercise by using stretchable dry electrodes is vital for healthcare monitoring,prosthetic control,human−machine interfaces and other biomedical applications.However,the existing dry electrodes are not applicable to the strenuous exercise situation that always involves both fast moving and profuse sweating.Herein,we present a nano-thick porous stretchable dry electrode system with high stretchability and water permeability.The system attaches conformably to the skin and stretches with it under Van der Waals forces even at sweating conditions,allowing the detection of electromyogram when moving with an acceleration of 10 g at a sweating rate of 2.8 mg cm^(−2) min^(−1).It is also capable of acquiring electrocardiogram and electroencephalogram signals.The strategy proposed would enable the biomedical studies and related applications with the requirement of stably recording electrophysiological signals under strenuous exercise scenarios. | Ruijie Xie Qingsong Li Lijun Teng Zhengshuai Cao Fei Han Qiong Tian Jing Sun Yang Zhao Mei Yu Dianpeng Qi Peizhi Guo Guanglin Li Fengwei Huo Zhiyuan Liu | 2022 | npj Flexible Electronics2022，6，1： | 0 |
