Behavior of Polyamide Brackish Water Reverse Osmosis Membranes in Acidic NaOCl Environment

open access: yesJournal of Applied Polymer Science, Volume 142, Issue 22, June 10, 2025.
The study investigates the effect of chlorination by NaOCl in acidic pH on RO membranes. A sudden drop in the pure water flux is observed post‐chlorine exposure, along with increased crystallinity of the polyamide layer; the flux increases after salt passage. This is attributed to conformational changes at low chlorine concentrations.

Clinical Application Guideline of Combination With Traditional Chinese Medicine and Western Medicine in the Prevention and Treatment of Chronic Obstructive Pulmonary Disease (2024)

open access: yesJournal of Evidence-Based Medicine, Volume 18, Issue 2, June 2025.
ABSTRACT Aim Chronic Obstructive Pulmonary Disease (COPD) is a common chronic airway disease that can lead to decreased lung function in patients. It places a heavy economic burden on patients and society. Traditional Chinese medicine (TCM) and Western medicine have played important roles in managing COPD.
