Reaching unconventionally large Hall-Petch coefficients in face-centered cubic high-entropy alloys

Autor: Jiaxiang Li, Kenta Yamanaka, Yongjie Zhang, Tadashi Furuhara, Guoqin Cao, Junhua Hu, Akihiko Chiba

Publikováno v: Materials Research Letters, Vol 12, Iss 6, Pp 399-407 (2024)

ABSTRACTThe Hall-Petch strengthening coefficient of face-centered cubic alloys has the potential to increase. Herein, we experimentally determined an unconventionally large Hall-Petch coefficient equal to 1100 MPa·µm1/2 and a large lattice friction

How Thick Aqueous Alkali Should be Better for Aluminum‐Air Batteries at Sub‐Zero Temperatures: A Critical Anti‐Freezing Concentration

Autor: Hongyu Cui, Ming Gao, Guoqin Cao, Fanfan Liu, Junhua Hu, Jinjin Ban

Publikováno v: Advanced Science, Vol 11, Iss 29, Pp n/a-n/a (2024)

Abstract The application of portable aluminum‐air batteries (AABs) in extreme environments is an inevitable demand for future development. Aqueous electrolyte freezing is a major challenge for low‐temperature operations. Conventionally, enlighten

Chemical regulation in the bonding reconstruction stage of amorphous Zr-Si oxidation and the resultant phase selection

Autor: Guoqin Cao, Chaoyang Chen, Hongjie Xu, Jinjin Ban, Fanfan Liu, Gaihuan Yuan, Honghong Lei, Yujie Su, Junhua Hu

Publikováno v: Materials & Design, Vol 233, Iss , Pp 112291- (2023)

A mechanism based on oxidation induced bonding reconstruction (OBR) was proposed to optimize phase selection during oxidation of amorphous ZrxSi1−x (0.55 ≤ x ≤ 0.75). According to VASP modeling, a self-barrier effect was proposed to regulate th

Recent advances based on Mg anodes and their interfacial modulation in Mg batteries

Autor: Fanfan Liu, Guoqin Cao, Jinjin Ban, Honghong Lei, Yan Zhang, Guosheng Shao, Aiguo Zhou, Li zhen Fan, Junhua Hu

Publikováno v: Journal of Magnesium and Alloys, Vol 10, Iss 10, Pp 2699-2716 (2022)

Magnesium (Mg) batteries (MBs), as post-lithium-ion batteries, have received great attention in recent years due to their advantages of high energy density, low cost, and safety insurance. However, the formation of passivation layers on the surface o
