چکیده
Back Cover: In article number 2000466 by Sandra Schlögl and co-workers, the introduction of photolabile o-nitrobenzyl ester chromophores endows epoxy-anhydride vitrimers with spatially controlled solubility properties. Positive-tone microstructures are inscribed photolithography patterns thermally erased via catalyzed transesterifications.

Rewritable Groups
A group G is said to have the n-rewritable property Qn if for all elements g1, g2, . . . , gn ∈ G, there exist two distinct permutations σ, τ ∈ Symn such that gσ(1)gσ(2) · · · gσ(n) = gτ(1)gτ(2) · · · gτ(n). We show here that if G satisfies Qn, then G has a characteristic subgroup N such that |G : N | and |N ′| are both finite and have sizes bounded by functions of n. This extends the result of...
متن کاملA photopatternable silicone for biological applications.
We show the application of a commercially available photopatternable silicone (PPS) that combines the advantageous features of both PDMS and SU-8 to address a critical bioMEMS materials deficiency. Using PPS, we demonstrate the ability to pattern free-standing mechanically isolated elastomeric structures on a silicon substrate: a feat that is challenging to accomplish using soft lithography-bas...
متن کاملGold Nanospheres Dispersed Light Responsive Epoxy Vitrimers
Vitrimers represent a new class of smart materials. They are covalently crosslinked like thermosets, yet they can be reprocessed like thermoplastics. The underlying mechanism is the rapid exchange reactions which form new bonds while breaking the old ones. So far, heating is the most widely used stimulus to activate the exchange reaction. Compared to heating, light not only is much more conveni...

Here we show the application of a commercially available photopatternable silicone (PPS) that combines advantages of both PDMS and SU-8 to address a critical need in material building blocks for bioMEMS. Using PPS we have demonstrated the ability to pattern free-standing mechanically isolated elastomeric structures on a silicon substrate, a feat challenging to approach using soft lithography-ba...
متن کاملRewritable Reference Attributed Grammars
This paper presents an object-oriented technique for rewriting abstract syntax trees in order to simplify compilation. The technique, Rewritable Reference Attributed Grammars (ReRAGs), is completely declarative and supports both rewrites and computations by means of attributes. We have implemented ReRAGs in our aspect-oriented compiler compiler tool JastAdd II. Our largest application is a comp...
