A thermostable trilayer resist for niobium lift-off

open access: yes, 1999
We have developped a novel lift-off process for fabrication of high quality superconducting submicron niobium structures. The process makes use of a thermostable polymer with a high transition temperature T_{g}= 235 C and an excellent chemical stability.

Compatibilization phenomenon in polymer science and technology: Chemical aspects

open access: yesAdvanced Industrial and Engineering Polymer Research
Polymer blends are mixtures of two or more macromolecular species – polymers and/or copolymers. They are used to increase the range of properties available from existing polymers without synthesizing new ones, which is time consuming and expensive.

Fine-tuned order-order phase transitions in giant surfactants via interfacial engineering

open access: yesGiant, 2020
Thermotropic order-order phase transitions (OOTs) in block copolymers are not commonly observed in the strong segregation region. Phase separation of giant surfactants composed of hydrophilic molecular nanoparticles (MNPs) as heads and hydrophobic ...
