“春节”--中国年,是中国人最重要的节日,它由上古时代岁首祈年祭祀演变而来,蕴含着中国人对自然万物生长周期的认识,在传承和发展中它成为我们开启来年生活的起点,凝聚着中华民族的文化认同。然而随着时代的发展,各种新事物的出现逐渐割裂了我们与自然的联系,年背后的意义逐渐模糊,年味儿也随之变淡。“中国年--文化与设计系列展”在思考年的文化含义、与当代人生活关系等的基础上,利用新的表现方式为年带来了活力,营造了浓浓的年味儿,各种在传统工艺基础上衍生的新作品使人见之欣喜。

Flexible perovskite solar cells(f-PSCs) have experienced rapid advancements due to the light-weight, flexibility, and solution processability of the perovskite materials, which prompted the power conversion efficiency(PCE) to 24.08%. However, f-PSCs still face challenges in terms of mechanical and environmental stability. This is primarily due to their inherent brittleness, the presence of residual tensile strain, and the high density of defects along the boundaries of perovskite grains. To this end, we carefully developed a cross-linkable elastomers 3-[(3-acrylamidopropyl)dimethylammonium] propanoate(ADP) with electrostatic dynamic bond, which could be in-situ cross-linked and coordinate with [Pb I6]4-to regulate the crystallization process of perovskite. The cross-linked elastomers attached to the perovskite grain boundaries could release the remaining tensile strains and mechanical stresses, leading to enhanced stability and flexibility of the f-PSCs. More importantly, the electrostatic interaction between positive and negative groups of cross-linked elastomers and hydrogen bond formation between N–H and C=O accelerate the cross-linking of ADP, endowing the flexible perovskite films with self-healing ability under mild treating conditions(60 °C for 30 min). As a result, the device achieves a remarkable PCE of 23.53%(certified 23.16%). Additionally, the device exhibits impressive mechanical sustainability and durability, retaining over 90% of initial PCE even after undergoing8,000 bending cycles.

采用MMW-1A多功能立式摩擦磨损试验机,以全因子设计的方法研究干摩擦条件下,载荷和转速两因素对摩擦因数与磨损量的影响。摩擦因数与磨损量的方差分析结果表明,转速对摩擦因数的影响更为显著,而载荷对Si C磨损量的影响更为显著。结合ABAQUS有限元分析软件对Si C陶瓷与45#钢的摩擦过程进行模拟仿真,得到摩擦过程中接触区域的应力分布,同时还探讨Si C陶瓷的磨损机制。结果表明:Si C陶瓷表面的最大等效应力位于接触区边缘,最大拉应力位于滑动前方,最大压应力位于滑动后方;不同应力下Si C陶瓷表面的磨损机制也不一样,主要表现为黏着磨损、磨粒磨损、犁沟磨损。
