The mechanical properties of selective laser melting (SLM) titanium (Ti) materials can be enhanced by solid solution with oxygen (O) element. However, the microstructure changes and their relationship SLM Ti have not been clearly revealed in view point dissolved amount. In this study, we investigated effect element on microstructures α-Ti materials. Furthermore, strengthening mechanism was also...

Origin DNA melting is an essential process in the various domains of life. The replication fork helicase unwinds DNA ahead of the replication fork, providing single-stranded DNA templates for the replicative polymerases. The replication fork helicase is a ring shaped-assembly that unwinds DNA by a steric exclusion mechanism in most DNA replication systems. While one strand of DNA passes through...

For the polymer-solvent system poly(pheny1enc oxide) in toluenc the mechanism and kinet~cs of crystallization have bccn studied w i f h the Pulsc lnduccd Critical Scattering technique. I t was found that aftcr a dclay-time r the growth mechanism was diffusion controlled. The delay-timc is thought to be conncctcd with the nucleation of thc crystallites and it disappeared in the "sceded" crystall...

The ability of the most popular models of methanol (H1, OPLS, L2, and L1) for the prediction of the solid-solid and the solid-fluid equilibria was analyzed in detail in this work by using molecular simulation. The three solid phases (α, β, and γ) detected experimentally as being thermodynamically stable, as well as the fluid phase, were considered for the calculations. It turns out that all the...

The carboxyl-functionalized phosphonium ionic liquid (IL), [HCTMP][Tf(2)N], enabled the directed nucleation of monomeric or dimeric uranyl(vi) compounds. This new IL is the first carboxyl-functionalized IL which is liquid at room temperature and exhibits a wider electrochemical window and lower melting point than its ammonium analogue.

Molecular dynamic simulations were performed for ice I(h) with a free surface by using four water models, SPC/E, TIP4P, TIP4P/Ice, and TIP4P/2005. The behavior of the basal plane, the primary prismatic plane, and of the secondary prismatic plane when exposed to vacuum was analyzed. We observe the formation of a thin liquid layer at the ice surface at temperatures below the melting point for all...

We theoretically predict a new phenomenon, namely, that a solid-solid phase transformation (PT) with a large transformation strain can occur via internal stress-induced virtual melting along the interface at temperatures significantly (more than 100 K) below the melting temperature. We show that the energy of elastic stresses, induced by transformation strain, increases the driving force for me...

Introduction The work presented in this paper concerns an experimental study of the melting of two-dimensional crystals in a Langmuir monolayer. In two dimensions, thermal fluctuations destroy the long-range positional order. Also, the resulting quasi long-range order in two-dimensional crystals is characterised by a very slow algebraic decay of the postional correlations [1]. The solids we stu...
