Impact of Processing Parameters on the Morphology and Performance of PE/PA6/EVOH Blends

open access: yesJournal of Applied Polymer Science, EarlyView.
Precise processing conditions enable the utilization of all components in multilayer films, resulting in improved morphology and mechanical properties. ABSTRACT This study employs a stepwise approach to investigate the influence of processing conditions and blend composition on the morphology and mechanical properties of immiscible polymer blends.

Supra and subgingival application of antiseptics or antibiotics during periodontal therapy

open access: yesPeriodontology 2000, EarlyView., 2023
Abstract Periodontal diseases (gingivitis and periodontitis) are characterized by inflammatory processes which arise as a result of disruption of the balance in the oral ecosystem. According to the current S3 level clinical practice guidelines, therapy of patients with periodontitis involves a stepwise approach that includes the control of the patient ...

Method for the preparation of thin-skinned asymmetric reverse osmosis membranes and products thereof [PDF]

open access: yes, 1984
A method for preparing water insoluble asymmetric membranes from water soluble polymers is discussed. The process involves casting a film of the polymer, partially drying it, and then contacting it with a concentrated solution of a transition metal salt.
