Emergent vortices at a ferromagnetic superconducting oxide interface by Petrović, A P, Paré, A, Paudel, T R, Lee, K, Holmes, S, Barnes, C H W, David, A, Wu, T, Tsymbal, E Y, Panagopoulos, C

“…This hysteresis is argued to arise from vortex depinning within a thin (< 20 nm) superconducting layer, mediated by discrete ferromagnetic dipoles located solely above the layer. The pinning strength may be modified by varying the superconducting channel thickness via electric field-effect doping. …”

Producing microscale Ge textures via titanium nitride- and nickel-assisted chemical etching with CMOS-compatibiliyty by Liao, Yikai, Shin, Sang-Ho, Jin, Yuhao, Wang, Qi Jie, Kim, Munho

“…Schottky contact barrier of metal catalyst with Ge is also investigated indicating similar hole injection efficiency among TiN, Ni, and Ti/Ni with Ge junction due to strong Fermi level pinning effect. The TiN- and Ni-assisted chemical etching of Ge shed light on CMOS-compatible Ge-based photonic and optoelectronic applications.…”

Additive friction stir processing by Lin, Longyi

“…The continuous dynamic recrystalisation during FSP also gave finer grains, which was further enhanced with the addition of CNTs through Zener pinning effect. The improvement in tensile strengths due to finer grains through the Hall-Petch mechanism was insufficient to compensate for the drop in Orowan strengthening. …”

Effects of heat treatment parameters on the microstructure and mechanical properties of laser power bed fusion (LPBF) 316L stainless steel by Sun, Yuheng

“…No obvious recrystallization was observed when the annealing temperature is below 1300 °C; annealing at 1200 °C for 30 minutes to 2 hours only led to partially recrystallization; full recrystallization was obtained at 1300 °C for more than 30 mins, where similar microstructure and mechanical properties were obtained to CM 316L. …”

Mechanics of fracture and flexure in Antarctic ice sheets and ice shelves by Zhang, H

“…In grounding zones and floating ice shelves, ice fracturing is often associated with flexure modulated by ocean tides and subglacial water flow, as well as stresses created by shearing, such as pinning points. Fracture and flexure significantly affect the vulnerability of Antarctic ice shelves to hydrofracturing and, by altering buttressing effects, the mass balance of the entire Antarctic Ice Sheet. …”
