Resonant Domain Wall Dynamics in a Three‐Dimensional Magnetic Nano Double Helix
3D magnetic nanostructures promise exciting possibilities for magnetization dynamics. However, experimental realizations remain scarce. In nanoprinted cobalt double helices, time‐resolved X‐ray microscopy reveals harmonic domain wall dynamics. Simulations identify the mode and additional higher‐frequency resonances, revealing a rich dynamic landscape ...

A Simple Model for Hardness and Residual Stress Profiles Prediction for Low-Alloy Nitrided Steel, Based on Nitriding-Induced Tempering Effects [PDF]
Nitriding of low-alloy steels is widely used for gears and bear- ings in aerospace industry. Some highly stressed surfaces re- quire high nitrided depth, which involves long time/high tem- perature nitriding treatment.

A novel W2TiC2Tx MXene prepared through a MAX‐phase route supports sub‐nanometer Co for highly efficient alkaline hydrogen evolution. Strong Co–W interfacial interactions optimize hydrogen adsorption and catalytic activity, enabling low overpotentials of 63 mV at 10 mA cm−2, small Tafel slope of 44.3 mV dec−1, and exceptional durability at industrially

Plasma nitriding in a glow discharge is a relatively new and extremely promising method of steel surface hardening. Ion-nitrided samples show a tendency to a longer lifespan during severe wear and cyclic loading compared to the traditional gas nitriding.

A novel polar wurtzite alloy, NbAlN, is demonstrated as a transition‐metal‐containing polar barrier for GaN heterostructures. Nb atoms form coherent nanoscale enrichment within the wurtzite lattice without disrupting metal polarity. This study demonstrates that transition metals can be integrated into polar nitrides to enable polarization‐related ...

Activation of surfaces prior to gaseous nitriding of a 3wt.% Cr carbon iron-based alloy [PDF]
Gaseous nitriding is a well-established thermochemical treatment of carbon iron-based alloys that considerably enhances corrosion, wear and fatigue resistances of critical mechanical parts such as crank shafts and bearings.

Nitriding of nanocrystalline pure Fe induced by surface mechanical attrition treatment
Properties of nanocrystalline (nc) materials are different from, and often superior to those of conventional coarse-grained counterparts. Unfortunately, it is still difficult to obtain “ideal” (e.g. full-density, residual stress-free, flaw-free, porosity-

Spatial‐Compatibility‐Assisted Molecular Intercalation in MXenes
This work demonstrates a solvent–free NH4F–mediated route for simultaneous Al removal and molecular intercalation in MXenes. Intercalants are selected by comparing their crystallographic X, Y, and Z dimensions with the MXene interlayer spacing, establishing a spatial‐compatibility criterion that rationalizes guest–host matching and enables predictive ...
