The superior strength and toughness of biological tissues have provided significant motivation for synthesizing advanced structural materials, while precisely reproducing the hierarchical microstructures materials remains a huge challenge. In this study, we developed nacre-inspired toughening ceramic composite by combining two brittle compounds (graphene calcium silicate) after rationally calculating reduced graphene oxide (rGO) backbone structure through vacuum-assisted perfusion followed...
Slag is a highly active waste product that can be added to alkali-activated cement improve their mechanical properties, but also creates significant shrinkage, which limits its usefulness. This study examines the reasons behind shrinkage of slag (AAS). The research uses comprehensive approach includes linear testing, comparative chemical analysis, microscopic structural characterization, internal relative humidity evaluations, pore size distribution assessments, and nanoindentation testing....

The trade-off between strength and toughness in traditional silicate-based materials presents a notable challenge engineering infrastructure. limited range of suitable components means that chemical modification does not fully address inherent brittleness. This study introduces novel coaxial 3D printing method to create tooth enamel biomimetic composites using stiff silicate flexible polyvinyl alcohol (PVA) as strengthening toughening agents, respectively. Unlike standard composites, this...
Additive manufacturing technology, by manipulating and emulating the inherent multiscale, multi-material, multifunctional structures found in nature, has created new opportunities for constructing heterogeneous associated with special properties achieving ultra-high mechanical performance reliability ceramic composite materials. In this study, we have developed an innovative fabrication method designated as coaxial 3D printing synchronous construction of two constituents into composites a...
We describe lightweight three-dimensional (3D) graphene hybrid SiO2 aerogels (GSAs) with hierarchically robust interconnected networks fabricated via an in situ deposition procedure after a hydrothermal assembling strategy oxide sheets. The nano-/micron-thick coating conformably grew over porous templates two constituents (e.g., and SiO2) formed chemically bonded interfaces. In addition, it significantly refined the primary pores by hundreds of microns into smaller patterns. Studies its...
Oil shale semi-coke (OSS) is a coal-based industrial solid waste produced after the dry distillation refining of oil shale. Due to its internal enrichment activity silico-aluminate minerals, it can be utilized prepare low-carbon cementitious materials through alkali activation. In this study, composite material for reinforcing loess was synthesized using OSS, lime, and cement. Drawing upon ternary design method, optimization semi-coke/lime/cement stabilized (OLC-SL) formulation explored....

Geopolymer containing slag is the most promising low-carbon cementitious material for replacing cement, but its large shrinkage characteristics limit application. This study takes alkali-activated (AAS) and ordinary Portland cement (OPC) as research objects systematically studies essential causes of AAS by combining linear testing, comparative characterization chemical composition, microstructural characterization, internal relative humidity pore size distribution nanoindentation testing....
The inherent trade-off between the strength and toughness of conventional silicate-based materials has become a significant hindrance in advancement engineering infrastructure. fairly limited selection appropriate components often makes chemical modification fail to overcome intrinsic brittleness. In this study, novel coaxial 3D printing methodology was developed fabricate tooth enamel biomimetic composite with stiff silicate flexible PVA serving as strengthening bridge toughening layer,...
