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

Reversing a Platinum Micromotor by Introducing Platinum Oxide

Angewandte Chemie, 2022
AbstractUnderstanding and controlling the swimming direction of a synthetic nano‐ and micromotor holds fundamental and applied significance. Here, we focus on platinum‐containing Janus colloids that catalytically decompose H2O2into O2, an archetypical model of chemical micromotor.

Platinum nephrotoxicity

The American Journal of Medicine, 1978
Platinum coordination complexes have recently been introduced in cancer chemotherapy with considerable success. However, significant nephrotoxicity has emerged as a factor that limits the therapeutic usefulness of these compounds. In this article we review the available knowledge on platinum nephrotoxicity and its prevention that has been derived from ...

The aluminization of platinum and platinum-coated IN-738

Metallurgical Transactions A, 1977
The chemistry and morphology of aluminide coatings formed on platinum and platinum-coated IN-738 have been studied. Most of the aluminide coatings evaluated were applied using the pack cementation process. For aluminized platinum a series of intermetallic Pt-Al compounds form.

Platinum silicide formation: Electron spectroscopy of the platinum-platinum silicide interface

Journal of Applied Physics, 1974
Platinum silicide formation has been studied by Auger electron spectroscopy (AES) and x-ray photoelectron spectroscopy (XPS) in conjunction with argon ion depth profiling. These techniques were used to probe the chemistry of the interface between the Pt metal and PtSi formed from two standard platinum deposition processes: dc sputtering and filament ...
