Mechanical properties change of immobilized skeletal muscle in short position measured by shear wave elastography and pure shearing test
J Mech Behav Biomed Mater. 2023 Dec 15;150:106317. doi: 10.1016/j.jmbbm.2023.106317. Online ahead of print.ABSTRACTThe purpose of this study was to evaluate the effects of immobilization on mechanical properties of skeletal muscle over the time. An in vivo rat model was used to investigate the shear modulus change of the flexor carpi ulnaris (FCU) in a short position. Measurements were performed by shear wave elastography (SWE) to compare contralateral and immobilized cases. The results showed a significant increase of 18.1% (p = 3.86. 10-7) in the shear modulus of immobilized skeletal muscle after two weeks (D14) when com...

Stress softening of nanoparticle-crosslinked hydrogels described using a physics-based damage model
J Mech Behav Biomed Mater. 2023 Dec 1;150:106282. doi: 10.1016/j.jmbbm.2023.106282. Online ahead of print.ABSTRACTDespite the promising applications of hydrogels, their poor mechanical properties still greatly limit their further applications. To improve the mechanical properties of hydrogels, various strategies have been proposed. Hydrogels with nanoparticle-crosslinked polymer networks show excellent toughness, self-recovery, and other advantages, and thus have great prospects for use in tissue engineering, artificial muscles, flexible electronics, and other fields. There have been experimental and theoretical studies of...

Influence of different post-processing methods on the dimensional accuracy of 3D-printed photopolymers for dental crown applications - A systematic review
CONCLUSION: It was found that post-processing washing times outside the prescribed instruction for use (IFU) may have an impact on the physical and biocompatibility characteristics of the material. Studies focusing on inert mediums during post-processing require more detailed investigation. The use of different post-curing conditions does not significantly affect the materials dimensional accuracy.PMID:38113824 | DOI:10.1016/j.jmbbm.2023.106314 (Source: Journal of the Mechanical Behavior of Biomedical Materials)

Melt electrowritten scaffold architectures to mimic tissue mechanics and guide neo-tissue orientation
J Mech Behav Biomed Mater. 2023 Dec 10;150:106292. doi: 10.1016/j.jmbbm.2023.106292. Online ahead of print.ABSTRACTAll human tissues present with unique mechanical properties critical to their function. This is achieved in part through the specific architecture of the extracellular matrix (ECM) fibres within each tissue. An example of this is seen in the walls of the vasculature where each layer presents with a unique ECM orientation critical to its functions. Current adopted vascular grafts to bypass a stenosed/damaged vessel fail to recapitulate this unique mechanical behaviour, particularly in the case of small diameter...

Electrochemical behavior and surface stability of dental zirconia ceramics in acidic environments
This study focuses on analyzing the electrochemical behavior of a commercial dental zirconia ceramic type in acidic environments. Through extensive electrochemical investigations, including Electrochemical Impedance Spectroscopy (EIS) and cyclic polarization resistance (Cpol), corrosion resistance was assessed. Despite indications of material dissolution, our results demonstrate significant corrosion resistance, as reflected in low corrosion current density (Icorr) values. Notably, the study reveals the development of a protective oxide layer at the ceramic-electrolyte interface, contributing to material stability. XRD ana...

The effect of phase contents on the properties of yttria stabilized zirconia dental materials fabricated by stereolithography-based additive manufacturing
J Mech Behav Biomed Mater. 2023 Dec 12;150:106313. doi: 10.1016/j.jmbbm.2023.106313. Online ahead of print.ABSTRACTThe aim is to investigate the impact of phase contents on mechanical properties, translucency, and aging stability of additively manufactured yttria partially stabilized zirconia ceramics. For that purpose, we evaluated two PSZ materials. The first type was prepared utilizing commercially available 5 mol% yttria-stabilized zirconia(5Y-PSZ), while the second type, denoted as 3Y+8Y-PSZ ceramics, was fabricated by blending 3 mol% and 8 mol% yttria-stabilized zirconia powders. Compared to 5Y-PSZ (39.90 wt% tetrago...
