Concrete has a broad task to carry out in both development and improvement of structural buildings and foundations. Based on its mass occupied per unit volume it can be classified as lightweight, ordinary or heavyweight concrete, each having its own unique applications. Heavy weight or high density concrete offers dep…
Abstract Newly developed nickel-titanium (NiTi) alloys are well suited for bearings and gears in demanding applications.
Abstract Dissimilar metals, each with their own special properties, can be integrated into a single composite wire to achieve a functionally driven design. Simultaneously strong, stiff, and superelastic guidewires that provide proximal stiffness and distal flexibility for medical applications are discussed in this art…
We report the synthesis and liquid crystalline properties of a new type of tribranched compound built up from triazine as the central core and electron-rich triazine rings as peripheral groups. An equimolar mixture of the star-shaped compound based on the 1,3,5-triazine core with 4-dodecyloxybenzoic acid produced an o…
The effect of corrosion environment aggressiveness on the tensile mechanical properties degradation of AA2024-T3 was investigated. Tensile specimens were pre-corroded for various exposure times to different corrosive solutions, i.e., exfoliation corrosion (EXCO) and 3.5 wt. % NaCl. Then they were tested mechanically.…
In this paper we investigate the effect of anisotropic growth on Glagov\nremodeling in different cases: pure radial, pure circumferential, pure axial\nand general anisotropic growth. We use the theory of morphoelasticity on an\naxisymmetric arterial domain. For each case we explore their specific effect on\nthe Glagov…
Since silicon nitride (SiNx) film is more stable than SiO2, silicon nitride, thus it is widely used in semiconductor industry as an insulatorlayer. The study of nitrogenation process of a-Si was performed using molecular dynamics simulations to determine the properties of the bonds created in the structure of a-SiNx.…
Bowman Additive, part of Bowman International, is adding value to the group’s core business of bearing design and supply, innovating via plastic additive manufacturing and replacing what is traditionally a pressed metal part. It is set to multiply the company’s turnover many-fold. Andrew Allcock has the details

The mechanisms causing the reduction in lattice thermal conductivity in\nhighly P- and B-doped Si are looked into in detail. Scattering rates of phonons\nby point defects, as well as by electrons, are calculated from first\nprinciples. Lattice thermal conductivities are calculated considering these\nscattering mechani…
We study high energy elastic and inelastic processes in a G3 theory based on the s-channel iterations of t-channel ladder diagrams.The main results are:(a) The total cross section goes to zero, a constant, or N @?n s)' for the coupling constant being smaller than, equal to, or larger than a critical value.P) Inelastic…
The reaction yp --po was studied in a hydrogen bubble chamber using a linearly polarized photon beam.The total cross section was found to be 5.8~0.5pb at 2.8 GeV and 3.2kO.3pb at 4.7 GeV.From the decay angular distributions these cross sections have been separated into N U contributions from natural and unnatural pari…

We\nhave developed a coarse-grained (CG) model of a polymer–clay\nsystem consisting of organically modified montmorillonite (oMMT) nanoclay\nas the nanoparticle in accordance with the MARTINI force field. We\nhave used mechanical properties and cleavage free energy of the clay\nparticle to respectively parameterize bo…
