Composition, silicate anion structure and morphology of calcium silicate hydrates (C-S-H) synthesised by silica-lime reaction and by controlled hydration of tricalcium silicate (C3S)

open access: yes, 2015
The main product of Portland cement hydration is C-S-H. Despite constituting more than half of the volume of hydrated pastes and having an important role in strength development, very little is known about the factors that determine its morphology.

Helicobacter pylori Detection Based on Synergistic Electromagnetic and Chemical Enhancement of Surface‐Enhanced Raman Scattering in 3D Hotspot‐Activated Gold Nanorods/Nano Mica Platelets/ZnO Quantum Dots

open access: yesAdvanced Science, EarlyView.
Gold nanorods hybridized with nano mica platelets and ZnO quantum dots are used for the rapid, sensitive, selective, and reproducible surface‐enhanced Raman scattering‐based detection of Helicobacter pylori in different scenarios. The origin of this high performance is ascribed to the synergy between the three operational enhancement mechanisms and the

Cryo‐Inactivated Cancer Cells Derived Magnetic Micromotors for Tumor Immunotherapy

open access: yesAdvanced Science, EarlyView.
Cryo‐inactivated cancer cell‐based magnetic micromotors are developed for synergistic tumor immunotherapy via magnetic targeting. These micromotors can induce ferroptosis and immunogenic cell death, deliver tumor antigens, and activate the Mn2+‐dependent cGAS‐STING pathway. The system effectively suppresses tumor progression, recurrence, and metastasis,
