Purpose: To introduce a hybrid wide-angle viewing-endoscopic vitrectomy, which we have reported, using a 3D visualization system developed recently.
Subjects And Methods: We report a single center, retrospective, consecutive surgical case series of 113 eyes that underwent 25 G vitrectomy (rhegmatogenous retinal detachment or proliferative vitreoretinopathy, 49 eyes; epiretinal membrane, 18 eyes; proliferative diabetic retinopathy, 17 eyes; vitreous opacity or vitreous hemorrhage, 11 eyes; macular hole, 11 eyes; vitreomacular traction syndrome, 4 eyes; and luxation of intraocular lens, 3 eyes).
Results: This system was successfully used to perform hybrid vitrectomy in the difficult cases, such as proliferative vitreoretinopathy and proliferative diabetic retinopathy.
Conclusion: Hybrid wide-angle viewing-endoscopic vitrectomy using a 3D visualization system appears to be a valuable and promising method for managing various types of vitreo-retinal disease.

UV Irradiation as a Versatile Low-Temperature Strategy for Fabricating Templated Mesoporous Titania Films.
Small
December 2024
Chair for Functional Materials, Department of Physics, TUM School of Natural Sciences, Technical University of Munich, James-Franck-Str. 1, 85748, Garching, Germany.
Mesoporous titania thin films offer promising applications in sensors, batteries, and solar cells. The traditional soft templating methods rely on high-temperature calcination, which is energy-intensive, incompatible with thermosensitive flexible substrates, and destructive for titania structures. This work demonstrates UV irradiation as a versatile low-temperature and energy-saving alternative for mesoporous crystalline titania fabrication.

Article Synopsis
- Wide-angle metalenses in the longwave infrared can outperform traditional lenses because they are lighter, more affordable, and compatible with CMOS technology.
- This study introduces two metasurfaces to correct common optical issues like distortion and spherical aberration, resulting in a hybrid metalens designed for thermal imaging in the 8-12 μm waveband.
- The new metalens shows impressive performance metrics, such as an FOV of 24°, an F-number of 1.2, and has potential applications in areas like camera technology, autonomous vehicles, healthcare, and environmental monitoring.
Self-assembly of mixed-linkage glucan hydrogels formed following EG16 digestion.

Article Synopsis
- - Mixed-linkage glucans (MLGs) in plant cell-walls and cereals have been shown to gel quickly when cleaved by a specific enzyme (endo-β-glucanase), creating a low molecular-weight product that has a repeating structure.
- - Research employing various techniques (rheology, microscopy, and X-ray scattering) revealed that the behavior of the material shifts from being like typical polymers to a more organized fibrillar network during digestion.
- - The findings suggest that gelation occurs not by strengthening self-assembly interactions, but by removing interactions that prevent the assembly of MLG, as indicated by structural changes observed during the study.
Probing Nanoscale Charge Transport Mechanisms in Quasi-2D Halide Perovskites for Photovoltaic Applications.
ACS Nano

School of Engineering, Macquarie University, Sydney, New South Wales 2109, Australia.
Quasi-2D layered halide perovskites (quasi-2DLPs) have emerged as promising materials for photovoltaic (PV) applications owing to their advantageous bandgap for absorbing visible light and the improved stability they enable. Their charge transport mechanism is heavily influenced by the grain orientation of their crystals as well as their nanostructures, such as grain boundaries (GBs) and edge states─the formation of which is inevitable in polycrystalline quasi-2DLP thin films. Despite their importance, the impact of these features on charge transport remains unexplored.
