Abstract Titanium alloys are ideally suited for use in implant or osteosynthesis applications due to their good mechanical properties, corrosion resistance, and biocompatibility. In terms of higher strength applications, Ti–6Al–4V Ti–6Al–7Nb frequently used. However, both contain the alloying elements aluminum and, former case, vanadium, which could have toxic effects on human body. Therefore, ...

A coupled heat source model that combined a Gauss surface with cylindrical volumetric was introduced to simulate temperature field distribution and melt pool characteristics using finite element simulation (FEM) method for the deep narrow pools formed in laser powder bed fusion (L-PBF) aiming at commercial pure titanium (CP-Ti). For comparison, same simulations double ellipsoid were also perfor...

Cyclotriarsanes are rare and described herein is a scalable synthetic protocol towards aryl-substituted derivatives. Their reactivity [Cp2Ti(C2(SiMe3)2)], affording titanocene diarsene complexes, N-heterocyclic carbenes (NHCs) discussed.

A study of the full dehydrogenation of hydrazine borane (H2N-NH2·BH3) to give H2 and N2 as gaseous products catalysed by a variety of group 4 metallocene alkyne complexes of the type CpM(L)(η(2)-Me3SiC2SiMe3) (Cp' = substituted or unsubstituted η(5)-cyclopentadienyl; M = Ti, no L; M = Zr, L = pyridine) and group 4 metallocene hydrides is presented. Volumetric data show that the amount of hydrog...

Titania and silica have been recognized as potential drug delivery system (DDS) carriers. For this application, controllable biocompatibility the suppression of initial burst are required, which can be provided by a calcium phosphate (CP) coating. However, it is difficult to control morphology CP coating on surface carrier particles owing homogeneous nucleation CP. In study, we report developme...

The titanium powder embedded with 2.5 vol% TiB was in-situ fabricated by gas atomization and applied for direct laser deposited (DLD) matrix composites. Consistent the network distributed boron-rich zone in composite powder, a three-dimensional (3D) ultrafine structure, consisting of nano-TiB whiskers (TiBw), characterized throughout as-fabricated (DLDed TiB–Ti). Both dendritic equiaxed network...
