Remarkable enhancement of thermal stability of epoxy resin through the incorporation of mesoporous silica micro-filler

open access: yesHeliyon, 2021
For the first time, we incorporated mesoporous micro-silica (5 μm, pore size = 50 nm) as a filler in epoxy resin aiming to enter polymer into the pore of the silica.

A solid with a hierarchical tetramodal micro-meso-macro pore size distribution [PDF]

open access: yes, 2013
Porous solids have an important role in addressing some of the major energy-related problems facing society. Here we describe a porous solid, alpha-MnO2, with a hierarchical tetramodal pore size distribution spanning the micro-, meso-and macro pore range,

Bioinspired Hierarchically Interconnected Supermacroporous Hydrogels via Dual‐Templating for Rapid Atmospheric Water Harvesting

open access: yesAdvanced Functional Materials, EarlyView.
Inspired by lung alveolar architecture, a dual‐templating strategy combining CO2 bubble and ice templating creates mechanically robust super‐macroporous hydrogels with highly interconnected transport pathways. The resulting material achieves 3.37× faster moisture sorption and 1.72× higher solar‐driven water release than single‐templated counterparts ...
