Clinical Relevance of Laser-Sintered Co-Cr Alloys for Prosthodontic Treatments: A Review
Published 2016“…For the purpose of this review the term laser sintering also refers to laser melting technologies. The review notes that although there has been considerable progress with laser-sintered Co-Cr alloys, there is still a gap in knowledge and hence, further studies need to be undertaken to ascertain their suitability and provide recommendations.…”

“Materials Science” Challenges in the Additive Manufacturing of Industrial Parts
Published 2016“…Additive Manufacturing (AM), somewhat like fusion welding, brings into play: (1) complex and interacting physical phenomena such as heat and mass transfer, phase changes (including melting, solidification, allotropic transformations and diffusion phenomena such as epitaxial growth, grain growth), (2) a number of process variables associated to the moving heat source (e.g., its power, power distribution, relative speed, size, all affecting energy density), its paths (e.g., linear, circular, oscillatory), and added metal feed rate via powder, wire, or ribbon, all controlling deposit dimensions, aspect-ratios, and properties, including defects. …”

Fabrication and characterization of protein-based tissue scaffold
Published 2011“…It was observed that the change in SF concentration does not affect the melting and crystallization behaviours of silk. And the spectra recorded from the structural analysis indicated the presence of secondary structures (α-helices and β-sheets) in amide I, II, III regions of protein. …”

A study of shape memory effect in hydrogel/polyethylene glycol hybrid
Published 2014“…Brief experiments were carried out and results show that HG/PEG hybrids do not experience volume expansion when heated above melting temperature of hybrid. Hybrids containing high weight percentage of PEG (> ~200 wt% of PEG) showed thermo-responsive shape memory effect, while hybrids containing lower weight percentage of PEG (< 100 wt% of PEG) became hard and brittle. …”
