A new green deal for climate challenges and urban regeneration

Techne, 2020
A zero-emission Europe by 2050, this is the objective declared by the President of the European Commission Ursula von der Leyen during the plenary of the EU Parliament last January. The European “green deal” is based on a thousand billion investment plan

Can one hear the shape of a saturation patch?

, 2002
The theory of the acoustics of patchy-saturation in porous media is used to analyze experimental data on wave velocity and attenuation in partially water saturated limestones. It is demonstrated that the theory can be used to deduce the value of V/A, the

Assembly of Cell‐Seeded 3D Printed Hydrogel Modules with Perfusable Channel Networks

Advanced Functional Materials, EarlyView.
Macroscale assembly was utilized to prepare perfusable tissue constructs from individually 3D printed hydrogel modules with embedded branched channel networks and port arrays for cell seeding. Novel multi‐material bioreactors were fabricated to facilitate the gluing of individual modules and the perfusion culture of assembled modular constructs seeded ...

A Non‐Reciprocal Architected Porous Medium

Advanced Functional Materials, EarlyView.
ABSTRACT In several fluid flow, energy‐dumping, and energy‐harvesting applications, a dominant flow direction or dominant resistance direction is desirable. In this study, we propose a simple modular geometry that doubles flow resistance in one direction relative to the opposite direction, while maintaining laminar viscous flow.

The design of the building envelope between innovation and experimentation

Techne, 2020
Peter Galison, philosopher of science, says that surfaces are not as we often describe them, that is, membranes that enclose spaces. The surfaces are active and highly structured parts, with a degree of complexity that allows them to size and order the ...

Engineering Intelligent Graphene Oxide‐Cellulose Membranes: Suppressing Thermal Runaway for a Safer Aqueous Zinc‐Ion Batteries

Advanced Functional Materials, EarlyView.
A novel thermos‐responsive hydroxypropyl cellulose/graphene oxide (HPC/GO) composite membrane is fabricated for reversible temperature‐gated ion transport in aqueous zinc‐ion batteries. Enabled by LCST‐driven structural transition, unimpeded ion diffusion at room temperature delivers high capacity, while elevated temperature suppresses transport; full ...
