Achieving Less Than 100 ppb Total Metal Ion Concentration in ESCAP Resins Synthesized by Atom Transfer Radical Polymerization

open access: yesMacromolecular Materials and Engineering, Volume 309, Issue 4, April 2024.
The environmentally stable chemical amplified photoresist resin is synthesized via atom transfer radical polymerization achieving polydispersity index as low as 1.25. It is then purified by ion exchange with two different resins, IRC747 and A15, which are effective at removing Cu and other metal ions.

PECVD and PEALD on polymer substrates (part II): Understanding and tuning of barrier and membrane properties of thin films

open access: yesPlasma Processes and Polymers, Volume 21, Issue 3, March 2024.
Recent results on the analysis of plasma/polymer interactions and the nucleation of ultrathin plasma films by plasma‐enhanced chemical vapor deposition and plasma‐enhanced atomic layer deposition on polymeric substrates are shown. The adjustment of deposition parameters and substrate selection leads to either effective diffusion barriers or films with ...

Multienzymatic Cascades and Nanomaterial Scaffolding—A Potential Way Forward for the Efficient Biosynthesis of Novel Chemical Products

open access: yesAdvanced Materials, Volume 36, Issue 5, February 1, 2024.
This review focuses on multienzyme cascades for the biosynthesis of novel compounds and how nanomaterials can potentially improve their efficiency. Recent successes in applying biosynthetic strategies for multi‐step, one‐pot reactions toward novel products of interest are highlighted.

Tg Confinement Effect of Random Copolymers of 4-tert-Butylstyrene and 4-Acetoxystyrene with Different Compositions.

open access: yesACS Macro Letters, 2019
We observe that the Tg confinement effect of polymer films can saturate with polymer-substrate interaction. Thickness dependences of the glass transition temperature, Tg(h0), of random copolymer films of 4-tert-butylstyrene (TBS) and 4-acetoxystyrene (AS)
