In this work, polystyrene-block-polymethyl methacrylate (PS-b-PMMA) block copolymers were synthesized by sequential living anionic polymerization with n-butyl lithium (n-BuLi) as the initiator, and ...

Table 1 Composition and molecular weight of the studied polystyrene-b-polyisoprene copolymers. The equilibrium microphase structures of block copolymers result from a competition between entropic and ...

With blazing speed and seemingly limitless digital memory, the personal computers of the early 1990s rocketed past those that ranked as state-of-the-art just a couple of years earlier. Within a few ...

A recently developed block copolymer could help push the limits of integration and miniaturization in semiconductor manufacturing, report scientists at Tokyo Institute of Technology (Tokyo Tech) and ...

(Nanowerk Spotlight) Block copolymer (BCP) lithography is a cost-effective, parallel, and scalable nanolithography for the densely packed periodic arrays of nanoscale features, whose typical dimension ...

All matter consists of one or more phases -- regions of space with uniform structure and physical properties. The common phases of H2O (solid, liquid and gas), also known as ice, water and steam, are ...

(Nanowerk News) Miniaturization is one of the fundamental qualities of modern electronics and is largely responsible for the incredible increments in performance witnessed over the past decades. To ...

The development hinged on chemical engineering and materials science professor Kechun Zhang and postdoctoral associate Mingyong Xiong first designing a biosynthetic route to make the six-membered ring ...

The design of block copolymers that self-assemble into various shapes has proved an attractive approach for nanoscale periodic patterning that can cover large areas. However, various approaches that ...

Nearly a decade after they first demonstrated that soft materials could guide the formation of superconductors, Cornell researchers have achieved a one-step, 3D printing method that produces ...

A recently developed block copolymer could help push the limits of integration and miniaturization in semiconductor manufacturing, report scientists. Chemically tailored for reliable directed ...
