The present work demonstrates a generalized strategy using water-only hydrothermal oxidation to construct complex biomimetic micronanostructures on a series of metals and alloys, resulting in superhydrophilic surfaces. This general approach is environmentally-benign and cost-effective, which offers a unique clue for the rational fabrication of micronanoscale architectures and superhydrophilic s...

Low strain hardening has hitherto been considered an intrinsic behavior for most nanocrystalline (NC) metals, due to their perceived inability to accumulate dislocations. In this Letter, we show strong strain hardening in NC nickel with a grain size of approximately 20 nm under large plastic strains. Contrary to common belief, we have observed significant dislocation accumulation in the grain i...

For the sustainable development of spintronic devices, a half-metallic ferromagnetic film needs to be developed as a spin source with exhibiting 100% spin polarisation at its Fermi level at room temperature. One of the most promising candidates for such a film is a Heusler-alloy film, which has already been proven to achieve the half-metallicity in the bulk region of the film. The Heusler alloy...

The semiempirical theories of mixtures developed by van Laar, Margules, Scatchard-Hamer, Wilson and Renon and Prausnitz are used to study the concentration fluctuations of binary liquid alloys formed among the alkali metals. Examination of the fitting capabilities of these theories leads to the conclusion that those of van Laar, Scatchard-Hamer and Renon and Prausnitz are appropriate both when ...

Metallic materials are the basis of dental materials science, which is an important part of dentistry. As a result of their good mechanical properties and some biological properties, metals are widely used in oral rehabilitation of dentition and mandibular defects, orthodontic and dental implants, as well as in the equipment for dental operations. Commonly used metals include nickel chromium, c...

Much of the early application and evolution of the high-temperature parametric relationships to data for aluminum alloys were carried out during the 1950s and 1960s under the auspices of the MPC, then known as the Metals Properties Council (now the Materials Properties Council). However, the real origins of the relationships go back considerably further. The “rate process theory” was first prop...

LLE Review, Volume 91 125 Introduction The transition metal–hydrogen systems have been intensively researched for many years because of the various applications of these systems. A large hydrogen solubility in some transition metals allows their use for safe and high-capacity hydrogen storage.1,2 At the other end of the spectrum, hydrogen ingress at low concentrations can induce mechanical degr...

The neutron eccmomy of a fast reactor is not so significantly affected by neutron capture in the structural materials in the core as is that of a thermal reactor. First, most neutron-capture cross sections increase with de­ creasing neutron energy, and the neutron population of the liquid-metal fast breeder reactor (Lhl FI~R) contains a far lower percentage of thermal neutrons than does that (I...

X-ray measurements reveal a crystalline monolayer at the surface of the eutectic liquid Au82Si18, at temperatures above the alloy's melting point. Surface-induced atomic layering, the hallmark of liquid metals, is also found below the crystalline monolayer. The layering depth, however, is threefold greater than that of all liquid metals studied to date. The crystallinity of the surface monolaye...
