“…In this way, porous materials with different porosities were obtained (Table ), and the wet materials were further treated by washing with ethanol (4 × 5 mL) and dichloromethane (3 × 5 mL). Then, they were dried in air, avoiding freeze‐drying and supercritical drying methods . The processes are schematically shown in Figure C.…”

Porous polymeric monoliths with densities as low as ≈0.060 g cm are prepared in a gel-emulsion template way, of which the stabilizer employed is a newly discovered acidified aramid fiber that is so efficient that 0.05% (w/v, accounts for continuous phase) is enough to gel the system. The porous monoliths as obtained can be dried at ambient conditions, avoiding energy-consuming processes. Importantly, the monoliths show selective adsorption to HCHO, and the corresponding adsorption capacity (M6) is ≈2700 mg g , the best result that is reported until now. More importantly, the monoliths can be reused after drying.

Abstract:The paper is proposing a method of image segmentation applied to the study of the micrographs of cellular solids. The segmentation is based on a thresholding which creates a binary (black and white) image of the micrograph. The binary image is divided in super-pixels which correspond to the microcells of the material. From the areas of the super-pixels it is easy to evaluate the distribution of the size of the cells and correlate this distribution to the properties of the material.

“…These microcellular foams were characterized by a cell density typically higher than 10 9 cells/cm 3 and small cells on the order 10 μm in diameter, which can significantly improve the thermal and sound insulation of the material . Moreover, by using ultrasonics, the foams became smaller and the porosity of the material was higher than the non‐sonicated samples . However, microcellular foams need high pressure and a long time to saturate the gas into the material, and the procedure is complicated, i.e., both gas saturation and high foaming temperature are required .…”

3D printing has been extensively applied in human‐related activities, and therefore the 3D printed nanocomposites became more popular and important in end‐use products. In the present study, we use lignin‐coated cellulose nanocrystal (L‐CNC) to reinforce 3D printed acrylonitrile butadiene styrene (ABS) and explore the effect of L‐CNC on the structural, mechanical, and thermal properties of 3D printed L‐CNC/ABS nanocomposites. The results indicate that the addition of L‐CNC foams the ABS and decreases the density of 3D printed L‐CNC/ABS nanocomposites. However, the tensile modulus and storage modulus increase by adding 4% L‐CNC. The thermal stability of 3D printed L‐CNC/ABS nanocomposites is also significantly improved as indicated by an increase in the maximum degradation temperature. The morphology of the nanocomposites reveals good dispersion and interfacial adhesion between L‐CNC and ABS. The finding indicates that the 3D printed nanocomposites become lighter and stiffer with addition of L‐CNC, which will have great potential to be applied in end‐use products. © 2017 Wiley Periodicals, Inc.
