X-ray imaging can provide detailed structural information in 3D non destructively across scales ranging from tens of centimetre samples to tens of nanometres spatial resolution over timescales ranging from milliseconds to many months. This, and the fact that 3D image sequences can be collected non destructively, mean that it can uniquely shine a light on a range of porous materials behaviours...
Additive manufacturing of porous ceramics is somewhat limited by their high melting temperatures and the processing issues related to handling of feedstocks containing a large volume of particles. Processing slurry-based feedstocks, in fact, poses several challenges: a high amount of powder is required to promote densification and results in high viscosity, scattering and sedimentation...
Achieving the temperature goals of the Paris Agreement will require 100 to 300 gigatons of carbon dioxide removal (CDR) this century. As large-scale interventions become central to climate planning, distinguishing between temporary carbon fluxes and durable atmospheric removals is essential. Yet the absence of robust and efficient monitoring, reporting and verification (MRV) frameworks remains...
Urban heat stress is becoming one of the most pressing challenges facing cities worldwide, particularly during increasingly frequent and intense heatwaves. This keynote demonstrates how porous materials can play an essential role in cooling urban environments and reducing heat exposure for pedestrians. Both natural and engineered porous systems are considered, including trees that provide...
Meso-structured, porous materials exhibit favorable charge, heat, and mass transport properties and are used as absorbers, heat exchangers, insulators, reaction sites, electrodes and/or reactants in a wide variety of applications ranging from chemical processing, (photo)electrochemistry, combustion, filtering, to concentrated solar reactor technology. The transport properties of these...
