This study aimed to demonstrate the laser retinopexy method through the gas bubble under a slit-lamp biomicroscope using a wide-field contact lens to treat rhegmatogenous retinal detachment (RRD) with pneumatic retinopexy (PR) and report its anatomical and functional results. This single-center, retrospective case series included RRD patients treated with PR using sulfur hexafluoride (SF). The demographics, preoperative factors, and anatomical and functional outcomes were collected from the patient files. The single-procedure success rate of PR at postoperative 6th months was 70.8% (17/24 eyes), and the final success rate after secondary surgeries was 100%. The BCVA was better in the successful PR eyes at postoperative 3rd ( = 0.011) and 6th month ( = 0.016) than in failed eyes. No single preoperative factor was associated with PR success. The single-procedure success rate of PR using the laser retinopexy method through the gas bubble with a wide-field contact lens system seems comparable to the PR literature.

Dissolved oxygen (DO) dramatically impacts the habitat use of many aquatic animals, particularly for air-breathing animals that rely on 'physical gills' for respiration while submerged. Invertebrates that use bubbles as physical gills directly uptake DO from the water for respiration. However, no vertebrate animals have yet been documented using physical gills.

Localized corrosion in metallic materials is a stochastic phenomenon that causes irreversible structural failure. Its initiation, which occurs at the solid-liquid interface on the nanometer scale, remains difficult to predict and challenging to characterize. Herein, we describe an experimental platform that exploits advances in electrochemical liquid-phase scanning and transmission electron microscopy (LPSEM and LPTEM) to study pitting corrosion of thin-film pure aluminum in a saline environment in real time.

Hypothesis: On highly cleaned planar surfaces submerged in highly cleaned water, flat surface nanobubbles with an angle of attachment of ∼15 are observed - never on engineering surfaces submerged in plain water, though here unidentified cavitation nuclei are always present and cause low tensile strength.
Experiments: In the present study, surface nanobubbles are generated by standard experimental techniques on a polished steel surface, and we find that the shape and the angles of attachment of the bubbles are influenced by the local substrate topography. These observations align with the theory of non-adsorbed liquid zones, which explains a surface nanobubble as a bubble with a skin of contamination molecules, which bond along the bubble rim at a contact angle of ∼14.

Flow fields (FFs) play multifaceted roles in direct methanol fuel cells (DMFC) by facilitating the transport and distribution of species, removal of products, support to the membrane electrode assembly (MEA), electrical conductivity, water, and thermal management. Therefore, the performance of DMFC is directly related to the pattern and geometry of the FF. DMFCs can generate power density of up to ≈100-300 mW cm; however, their performance is impeded by cathode flooding, CO gas bubbles formation, and mass transfer limitations.
