Use of compression sutures and intracameral injection of perfluoropropane (C3F8) gas in the management of acute corneal hydrops in a pediatric patient: a case report [PDF]

open access: yesRevista Brasileira de Oftalmologia
Acute corneal hydrops is an ophthalmologic emergency resulting from rupture of Descemet's membrane with entry of aqueous humor into the corneal stroma. Patients typically present with ocular pain, blurred vision, photophobia, and tearing.

Computational Chemistry‐Driven Advances in Eco‐Friendly Insulation Gas Research: Multi‐Dimensional Prediction, Synergistic Screening, Stability Evaluation and Molecular Design

open access: yesHigh Voltage, EarlyView.
ABSTRACT Sulphur hexafluoride has become a priority substance for greenhouse gas mitigation in electric systems. An ideal substitute should simultaneously satisfy requirements for dielectric strength, boiling point, global warming potential and chemical stability; however, these metrics are deeply coupled and mutually constraining at the molecular ...

Evaluation of Varnishes to Slow Down the Aging of Plasticized PVC

open access: yesJournal of Applied Polymer Science, Volume 143, Issue 43, November 15, 2026.
Varnish effectiveness in plasticized PVC strongly depends on both formulation and degradation state. A polyurethane varnish effectively limits color change and plasticizer loss in unaged PVC without phosphate plasticizers, whereas no protective effect is observed for phosphate‐containing PVC.

Dietary Interventions May Mitigate Health Risks of Per‐ and Polyfluoroalkyl Substances (PFAS) Exposure Through Modulation of the Gut Microbiota: A Review

open access: yesFood Frontiers, Volume 7, Issue 6, November 2026.
Dietary interventions, including probiotics, prebiotics, and synbiotics, may modulate gut microbiota to regulate PFAS accumulation and elimination. Specific microbial taxa facilitate PFAS removal through adsorption and bioaccumulation, potentially reducing internal PFAS burden and mitigating PFAS‐related health risks.

Sorption and desorption processes affecting the enrichment of the fluorocarbons CCl₂F₂ and CCl₃F in ground water

open access: yes, 1981
Field measurements of CCl₃F and CCl₂F₂ in ground water have shown that concentrations in recharge areas may be higher than those in water at equilibrium with the atmosphere.
