Regulation of cell morphology and viability using anodic aluminum oxide with custom-tailored structural parameters Front. Mater. Sci. (IF 2.7) Pub Date : 2022-11-17 Zhiying Zhang, Ting Liu, Juan Li, Yiyan Guo, Ruiqing Liang, Jiangbo Lu, Runguang Sun, Jun Dong
Anodic aluminum oxide (AAO) with independently controlled period, porosity, and height is used as the model surface to study the single structural parameter effect on breast cancer cell behaviors, including cell polarity and cell viability. It is found that the quantity of multipolar cells and cell viability increases as the nanodent period increases from 100 to 300 nm, while the number of bipolar

Regulation effect of osteoblasts towards osteocytes by silk fibroin encapsulation Front. Mater. Sci. (IF 2.7) Pub Date : 2022-10-14 Dandan Luo, Rui Zhang, Shibo Wang, M. Zubair Iqbal, Ruibo Zhao, Xiangdong Kong
Herein, the rational design micromilieus involved silk fibroin (SF)-based materials have been used to encapsulate the osteoblasts, forming an extracellular coated shell on the cells, which exhibited the high potential to shift the regulation of osteoblasts to osteocytes by encapsulation cues. SF coating treated cells showed a change in cell morphology from osteoblasts-like to osteocytes-like shape

Construction of mechanically robust superamphiphobic surfaces on fiber using large particles Front. Mater. Sci. (IF 2.7) Pub Date : 2022-10-11 Chang Lv, Jinyi Wang, Qirong Tian, Zhicheng Zhang, Tao Wang, Rongfei Liu, Sheng Wang
Superamphiphobic surfaces have attracted the attention of researchers because of their broad application prospects. Currently, superamphiphobicity is primarily achieved by minimizing the solid—liquid contact area. Over the past few decades, researchers have primarily focused on using physical deposition methods to construct superamphiphobic surfaces using fine-sized nanoparticles (< 100 nm). However

Enhanced superelasticity of Cu—Al—Ni shape memory alloys with strong orientation prepared by horizontal continuous casting Front. Mater. Sci. (IF 2.7) Pub Date : 2022-10-11 Mengwei Wu, Yu Xiao, Zhuofan Hu, Ruiping Liu, Chunmei Ma
The preparation of large-scale Cu—Al—Ni shape memory alloys with excellent microstructure and texture is a significant challenge in this field. In this study, large-scale Cu—Al—Ni shape memory alloy (SMA) slabs with good surface quality and strong orientation were prepared by the horizontal continuous casting (HCC). The microstructure and mechanical properties were compared with the ordinary casting
