Karl Popper and the Mechanisms of Hydrogen Embrittlement
Advanced Engineering Materials, EarlyView.Representation of the beginning of loss of ductility rather than embrittlement. Small concentrations of hydrogen in a diffusible form within iron are well‐established to harm the mechanical integrity of steels. There are theories that attempt to explain the pernicious role of hydrogen.

Ion-Beam Mixing in Layered Systems
Успехи физики металлов, 2010 Thickness of silicide phases at Mo-on-Si and Si-on-Мо interfaces increases identically and linearly with a dose of irradiation at the small doses (by He+ ions to Φ≤5⋅1020 ion/m2 and Ar+ ions to Φ≤1.3⋅1018 ion/m2).

Advanced Engineering Materials, EarlyView.Copper‐based composites enhanced with carbon feature convenient mechanical properties and favorable electric conductivity. Processing via deformation and thermomechanical treatments can introduce advantageous microstructures further enhancing their performance. Herein, copper–graphene powder‐based composites are directly consolidated via rotary swaging

Enhanced Sputtering Yields from Single-Ion Impacts on Gold Nanorods [PDF]
, 2013 Sputtering yields, enhanced by more than an order of magnitude, have been observed for 80 keV Xe ion irradiation of monocrystalline Au nanorods. Yields are in the range 100–1900 atoms/ion compared with values for a flat surface of ≈50.

Surface nanostructuring of titanium alloy dental screws by 10 keV Ar+ irradiation
Results in Surfaces and InterfacesThe influence of 10 keV Ar+ ion irradiation on the surface topography of Ti–6Al–4V dental screws was investigated. The surface facing the ion beam became uniformly covered with nanoprotrusions, the size of which increased with the ion fluence.

Advanced Engineering Materials, EarlyView.We develop a data‐driven method to derive the mathematical expressions of the Flory–Huggins interaction parameter χ for the swelling behavior of temperature–responsive hydrogels. Starting from initial assumptions of χ, our workflow combines Bayesian optimization, Flory–Rehner theory, and symbolic regression to generate candidate χ expressions.

Hydrogen‐Assisted Fracture of Iron‐Based Fe–Ni–Al Alloys
Advanced Engineering Materials, EarlyView.Principal relations and fracture mechanisms of single‐phase and precipitate‐strengthened Fe–Ni–Al alloys subjected to prior electrochemical hydrogen charging are identified. The mechanisms of hydrogen effect on strength and microhardness are discussed, including hydrogen‐induced increase in microhardness and the role of hydrogen in fracture behavior ...
