Article Synopsis
- The study focuses on Au-MoS nanocomposites, which combine gold nanoparticles with MoS nanosheets to enhance visible-light photocatalytic activity for degrading organic dyes, particularly methylene blue (MB).
- Researchers used a pulsed laser method to create these nanocomposites and examined how varying gold content affects their performance under visible light, revealing that Au NPs improve light absorption and electron transfer.
- The findings highlight that the interaction between positively charged MB and the negatively charged MoS surface, along with the generation of reactive oxygen species, contributes to efficient dye degradation, while also suggesting that the gold contributes to better photocatalytic properties in these nanocomposites.
In this study, we investigated the use of porous silicon (PSi) fabricated using metal-assisted chemical etching (MACE) as a substrate for the deposition of Au nanoparticles (NPs) for the reduction of nitroaromatic compounds. PSi provides a high surface area for the deposition of Au NPs, and MACE allows for the fabrication of a well-defined porous structure in a single step. We used the reduction of -nitroaniline as a model reaction to evaluate the catalytic activity of Au NPs on PSi.

A total of 120 consecutive patients (240 eyes) underwent visual acuity test with an iPad 2 and a conventional light-box chart. The logMAR VA results from the iPad were significantly higher than those from the light-box (P < 0.

Objective: To study the development of lymphatic vessels after keratoplasty and to explore the molecular mechanisms of corneal lymphangiogenesis in transplanted corneas.
Methods: Experimental research. The development of corneal lymphangiogenesis was examined by LYVE-1 immunohistochemistry and whole mount immunofluorescence 1, 3, 7, 10, 14, 30 and 60 days after corneal transplantation, then lymphatic vessels counting (LVC)was evaluated.

Objective: To explore the lymphangiogenesis process in alkali burned human cornea and to discuss factors modulating this process.
Methods: It was a retrospective case series study. Twenty-two cases (22 eyes) of hospitalized patients suffering from alkali burned cornea and requiring keratoplasty from January to December 2005 were analyzed retrospectively.

Objective: To evaluate the efficacy and safety of keratoplasty combined with corneal foci resection in the treatment of Terrien's marginal degeneration (TMD).
Methods: In this nonrandomized retrospective case series, the records of 48 eyes from 40 patients with TMD who received keratoplasty from January 1995 to December 2005 in Zhongshan Ophthalmic Center were reviewed retrospectively. Orbscan topography examination was undertaken in 8 eyes of 8 patients and the refractive error of 9 eyes from 9 patients was tested before and after the operation.
