Due to the non-renewable nature of the vitreous, artificial vitreous are usually required to replace natural vitreous to perform functions post operation. Silicone oil and gas, as the most commonly used vitreous substitutes, have obvious drawbacks, which may lead to postoperative posture maintenance, visual impairment, cataract formation and secondary surgery. In this study, an in situ cross-linked bionic hydrogel (OAHA-CDHA/Col) based on hyaluronic acid (HA) and collagen (Col) with available gelling time for clinical operation, excellent self-healing and fatigue resistance, as well as suitable mechanical and optical properties is constructed. The compatibility and degradability of OAHA-CDHA/Col hydrogel are verified, as well as the feasibility as vitreous substitute in rabbit vitrectomy model. Notably, the hydrogel demonstrates improved intraocular tolerance compared with silicone oil, with no cataracts, endophthalmitis, fundus lesions and other complications observed. These findings position the OAHA-CDHA/Col hydrogel as a promising candidate for an ideal vitreous substitute.","source":"DOAJ","year":2026,"language":"","subjects":["Materials of engineering and construction.

Intersecting cylindrical shells are considered as part of a large-scale three-dimensional “shell - soil” system. The study identified the most stressed areas of intersecting shells that require special attention during the modeling process. It should be noted that the particular complexity of these models lies in their high computational dimensionality since they include both the structure under consideration and its surrounding soil, which imposes additional requirements on the software packages used to solve such problems. Using modern methods of numerical analysis can significantly improve the quality of modeling and increase the accuracy of the results obtained. In particular, by considering the nonlinear properties of materials, it is possible to more accurately assess the actual behavior of shells under different external influences. In addition, the analysis shows that accounting for construction stages has a significant impact on the distribution of stresses in the intersecting shells. This underscores the need to consider the sequence of construction works, which in turn can contribute to increasing the overall reliability of the structure.
