Dynamic Electrophoretic Assembly Coupled With Water‐Splitting‐Induced pH Control Enables Precision Ion Sieving Membranes

open access: yesAdvanced Materials, EarlyView.
A green, external‐catalyst‐free route grows defect‐free covalent organic framework membranes directly on ion‐exchange supports using an alternating electric field and in situ‐generated acid. Through a self‐regulating, self‐healing mechanism, the membranes achieve near‐complete, ultra‐fast separation of monovalent ions such as Li+, Na+, and K+, offering

Hipertonia plasmática na criança.

open access: yesActa Médica Portuguesa, 2010
The plasma hypertonicity is a severe and quite frequent disorder in children. The most frequent causes are hypernatremia related conditions, even though other causes of hyperosmolarity, such as hyperglycaemia and exogenous solutes accumulation also occur.
