Triply periodic minimal surfaces have garnered significant interest in the field of biomaterial scaffolds due to their unique structural properties, including a high surface-to-volume (S/V) ratio, tunable permeability, and the potential for enhanced biocompatibility. Bone scaffolds necessitate specific features to effectively support tissue regeneration. This study examines the permeability and active cell proliferation area of advanced Triply Periodic Minimal Surface (TPMS) lattice structures, focusing on a novel lattice design.

Pipeline cleaning is essential for maintaining water quality and safeguarding public health within water distribution networks. Although ice slurry pigging is widely adopted due to its effectiveness and environmental advantages, challenges remain in accurately quantifying cleaning efficacy and optimising maintenance intervals. This study develops a stress-driven wall material removal model calibrated using field-measured turbidity data, allowing for a comprehensive assessment of cleaning effectiveness based on post-cleaning shear resistance.

Background: Carotid web (CaW) is a rare fibromuscular dysplasia lesion at the carotid bifurcation linked to thromboembolic events in young patients. CaW-induced hemodynamic disturbances contribute to thrombosis, but the impact of CaW morphology on long-term thrombotic risk remains unclear.
Method: This study developed three-dimensional numerical models based on patient-specific carotid artery anatomy with CaW angles of 30°, 60°, and 90° (models A, B, and C).

Background: Identifying haemodynamic factors associated with thin-walled regions (TWRs) of intracranial aneurysms is critical for improving pre-surgical rupture risk assessment. Intraoperatively, these regions are visually distinguished by a red, translucent appearance and are considered highly rupture prone. However, current imaging modalities lack the resolution to detect such vulnerable areas preoperatively.

While only a minority of CHDs have identifiable genetic causes, the functional roles of mechanical forces in OFT remodeling are far less characterized. A key barrier has been the lack of longitudinal investigations examining the interplay between dynamic blood flow and wall motion across clinically relevant stages.
