“…The same was also obtained for the Guinier crossover of sample K at high q. This value has been reported as the distance between metal-oxo domains embedded in the siloxane network [62][63][64], which is in agreement with the results of 29 Si MAS NMR, that indicated the maintenance of the full coordinated Q 4 signal in cross-polarization mode. …”

“…According to Wenzel model [28,29] roughness increases the surface area of a solid, enhancing its hydrophobicity. Moreover, air can remain trapped below the drop, leading to a super hydrophobic behavior, in which the drop sits partially on air creating a non-filling regime where the liquid does not penetrate into surface grooves (Cassie-Baxter model) [28].…”

Depending on the applied model (filling or non-filling regime) Young contact angle (θY) values can be calculated using the Wenzel equation [29] described by cos θm = Rw cos θY…”

Two biocompatible PDMS-SiO 2 -TiO 2 -CaO porous hybrid materials were prepared using the same base composition, precursors, and solvents, but following two different sol-gel procedures, based on the authors' previous works where for the first time, in this hybrid system, calcium acetate was used as calcium source. The two different procedures resulted in monolithic materials with different structures, microstructures, and surface wettability. Even though both are highly hydrophobic (contact angles of 127.2° and 150.6°), and present different filling regimes due to different surface topographies, they have demonstrated to be biocompatible when tested with human osteoblastic cells, against the accepted idea that high-hydrophobic surfaces are not suitable to cell adhesion and proliferation. At the nanoscale, the existence of hydrophilic silica domains containing calcium, where water molecules are physisorbed, is assumed to support this capability, as discussed.

Fabrication of Coaxial Wet‐Spun Graphene–Chitosan Biofibers

et al. 2015

One-step continuous wet-spinning of coaxial electroactive fibres of chitosan/graphene oxide (Chit/GO) via a facile method is introduced for the first time, eliminating the need for posttreatment processes. Spinnability of coaxial fibres as well as their characterization for several properties is investigated. L-ascorbic acid was found to reduce graphene oxide under mild conditions to create conductivity in the final fibre. As-prepared fibres were found to be cytocompatible with good electrical conductivity and mechanical properties. SEM images from the cross-section of Chit/GO fibres showed an irregular shaped multifilament GO fibre covered with a cylinder-shaped sheath of chitosan. Coaxial fibres had an ultimate tensile stress and elastic modulus that increased 8 500% and 3 350%, respectively compared to the graphene oxide fibres alone.

Additive Manufacturing of Titanium Alloys for Orthopedic Applications: A Materials Science Viewpoint

et al. 2018

Titanium‐based orthopedic implants are increasingly being fabricated using additive manufacturing (AM) processes such as selective laser melting (SLM), direct laser deposition (DLD), and electron beam melting (EBM). These techniques have the potential to not only produce implants with properties comparable to conventionally manufactured implants, but also improve on standard implant models. These models can be customized for individual patients using medical data, and design features, such as latticing, hierarchical scaffolds, or features to complement patient anatomy, can be added using AM to produce highly functional patient‐anatomy‐specific implants. Alloying prospects made possible through AM allow for the production of Ti‐based parts with compositions designed to reduce modulus and stress shielding while improving bone fixation and formation. The design‐to‐process lead time can be drastically shortened using AM and associated post‐processing, making possible the production of tailored implants for individual patients. This review examines the process and product characteristics of the three major metallic AM techniques and assesses the potential for these in the increased global uptake of AM in orthopedic implant fabrication.
