Intratumoral synthesis of nano-metalchelate for tumor catalytic therapy by ligand field-enhanced coordination

Nature Communications, 2021
Iron gall chelate (GA-Fe) can promote oxygen reduction reactions and reactive oxygen species generation which causes chemical corrosion. Here, the authors, inspired by this phenomenon, develop a composite nanomedicine for tumour therapy constructed by ...

Fabrication and mechanical behavior of 2D-Cf/TaxHf1−xC–SiC composites by a low-temperature and highly-efficient route

Journal of Advanced Ceramics, 2023
Cf/TaxHf1−xC–SiC composites are ideal thermal structural materials for service under extreme conditions of hypersonic vehicles. However, how to synthesize TaxHf1-xC powders and efficiently fabricate Cf/TaxHf1-xC–SiC composites still faces some challenges.

Dual fluorination of polymer electrolyte and conversion-type cathode for high-capacity all-solid-state lithium metal batteries

Nature Communications, 2022
The practical use of all-solid-state batteries is hindered by inadequate cycling performance. Here, the authors propose a fluorination strategy for the positive electrode and polymeric electrolyte to develop all-solid-state Li||FeF3 pouch cells with high

Thermal-inert and ohmic-contact interface for high performance half-Heusler based thermoelectric generator

Nature Communications, 2022
Unsatisfied electrode bonding in half-Heusler devices limits their practical service at high temperatures. Here, the authors develop a direct bonding interface to ideal ohmic contact and thermally inert and ohmic contact, leading to high deficiency.

Microstructure of ceramic foams [PDF]

Journal of the European Ceramic Society, 2000
This paper describes the preparation of ceramic foams by expansion of a ceramic suspension based on a polyurethane system. The microstructure and degree of reticulation of the foamed ceramic were examined and analysed with the help of a simple geometrical model.
