Carbon nanotube fibers(CNTF), serving as one-dimensional macroscopic assemblies of carbon nanotubes(CNT), possess significant potential in translating the unique physical and chemical attributes of CNT from the nanoscale to the macroscale. Theoretically, the efficient interconnection and bottom-up integration of CNTs can facilitate the direct translation of their remarkable mechanical, electrical, and thermal properties from the microscale onto macroscopic fibers. Nevertheless, practical obstacles, including suboptimal CNT alignment during assembly, low packing density, and structural defects such as voids, hinder the effective translation of nanotube properties to the larger material scale. Recent advancements in CNT composite fibers demonstrate promising potential in addressing structural imperfections and enhancing property translation at the macroscale. This review comprehensively summarizes the latest research progress in carbon nanotube composite fibers, encompassing various preparation techniques and the subsequent fiber properties. These include nanomaterial/CNT composite fibers, polymer/CNT composite fibers, metal/CNT composite fibers, and ceramic/CNT composite fibers. A critical examination of both local and international research statuses pertaining to the enhancements in strength, conductivity, and thermal stability of these composite fibers is also presented. Finally, the review provides prognostications on the future development trajectory of carbon nanotube composite fibers. [ABSTRACT FROM AUTHOR]

Aim: To study the efficiency and safety of iris reconstruction combined with iris-claw intraocular lens (IOL) implantation in the patients with iris-lens injuries.Settings and Design: Retrospective, noncomparable consecutive case series study.Materials and Methods: Eleven patients (11 eyes) following iris-lens injuries underwent iris reconstructions combined with iris-claw IOL implantations. Clinical data, such as cause and time of injury, visual acuity (VA), iris and lens injuries, surgical intervention, follow-up period, corneal endothelial cell count, and optical coherence tomography, were collected.Results: Uncorrected VA (UCVA) in all injured eyes before combined surgery was equal to or <20/1000. Within a 1.1-4.2-year follow-up period, a significant increase, equal to or better than 20/66, in UCVA was observed in six (55%) cases, and in best-corrected VA (BCVA) was observed in nine (82%) cases. Postoperative BCVA was 20/40 or better in seven cases (64%). After combined surgery, the iris returned to its natural round shape or smaller pupil, and the iris-claw IOLs in the 11 eyes were well-positioned on the anterior surface of reconstructed iris. No complications occurred in those patients.Conclusions: Iris reconstruction combined with iris-claw IOL implantation is a safe and efficient procedure for an eye with iris-lens injury in the absence of capsular support.

We report two posttraumatic fungal endophthalmitis cases with anterior and entire segment involvement caused, respectively, by Candida albicans and Aspergillus fumigatus. The anterior endophthalmitis induced by C. albicans presented multifocal lesions with hyphael structures in anterior chamber, but without involvement of posterior vitreous. The pan-endophthalmitis caused by A. fumigatus displayed significant hypopyon and vitritis. Treatment strategies are anterior chamber cleaning for anterior endophthalmitis and vitrectomy for pan-endophthalmitis, excepting systemic and topical antifungal drug applications including intravitreal injection for both types of endophthalmitis. There is a much better outcome in the case with anterior segment involvement than that with entire segment involvement. This case report provides evidence that the different types of posttraumatic fungal endophthalmitis related to different fungal infections indeed existed and should be managed with different strategies.
