Insights into freeze-cast hierarchical water–glass foams via in situ time-lapse phase-contrast enhanced microcomputed tomography: Correlating composition, microstructure, and compression failure

Autor: Liu Yang, Jonas Bansemer, Paul Zaslansky, Oliver Görke, Claudia Fleck

Publikováno v: Materials & Design, Vol 246, Iss , Pp 113354- (2024)

We demonstrate how continuous freeze-casting without post-treatment sintering may be successfully employed using a pure water–glass (WG) solution to fabricate hierarchically porous foams lacking a morphology gradient along the freeze direction. By

3D printing of multi-scale porous β-tricalcium phosphate scaffolds: Mechanical properties and degradation

Autor: Shareen S.L. Chan, Daniel E. Heath, George V. Franks

Publikováno v: Open Ceramics, Vol 19, Iss , Pp 100630- (2024)

Processing-structure-property relationships of 3D-printed multi-scale porous ceramics were investigated. Direct ink writing (DIW) of oil-templated colloidal pastes produced hierarchically porous beta-tricalcium phosphate (TCP) scaffolds. Print archit

Autor: Albena Daskalova, Matthias Ahlhelm, Liliya Angelova, Emil Filipov, Georgi Avdeev, Dragomir Tatchev, Maria-Helena Fernandes, Sanjana Vig, Ivan Buchvarov

Publikováno v: Frontiers in Cell and Developmental Biology, Vol 12 (2024)

Bone substitutes are widely employed for applications in orthopedic surgery for the replacement of injured bone. Among the diverse methods that are used to design 3D bioceramic matrices, Freeze Foaming has gained attention, since it provides the abil

Rational Design of Poly(phenylene sulfide) Aerogels Through Precision Processing

Autor: Godshall, Garrett Francis

Poly(phenylene sulfide) (PPS), an engineering thermoplastic with excellent mechanical, thermal, and chemical properties, was gelled for the first time using 1,3-diphenylacetone (DPA) as the gelation solvent in a thermally induced phase separation (TI

Mesoporous Carbons and Highly Cross-Linking Polymers for Removal of Cationic Dyes from Aqueous Solutions—Studies on Adsorption Equilibrium and Kinetics

Autor: Malgorzata Zienkiewicz-Strzalka, Magdalena Blachnio, Anna Derylo-Marczewska, Szymon Winter, Malgorzata Maciejewska

Publikováno v: Materials, Vol 17, Iss 6, p 1374 (2024)

This study presents the results of applying the methods of synthesizing mesoporous carbon and mesoporous polymer materials with an extended porous mesostructure as adsorbents for cationic dye molecules. Both types of adsorbents are synthetic material

Preparation and Characterization of a Hierarchically Porous Zeolite-Carbon Composite from Economical Materials and Green Method

Autor: Nargis H. Ibrahim, Sama M. Al-Jubouri, Abdullatif Alfutimie

Publikováno v: Iraqi Journal of Chemical and Petroleum Engineering, Vol 24, Iss 3 (2023)

A hierarchically porous structured zeolite composite was synthesized from NaX zeolite supported on carbonaceous porous material produced by thermal treatment for plum stones which is an agro-waste. This kind of inorganic-organic composite has an impr
