Surface‐Engineered Cenospheres Encapsulating Phase Change Materials for Functional Cementitious Composites

open access: yesAdvanced Science, EarlyView.
The global energy demand drives the need for advanced energy‐efficient building solutions. While current polymeric‐shell microencapsulated PCMs show promise for thermal energy storage, their use in cementitious materials is challenged by poor shell strength and interfacial bonding. This study develops novel cement‐compatible microencapsulated PCM using

Comparative study of microwave absorption in Ni/SiO2 and SiO2/Ni core-shell structures [PDF]

open access: yesarXiv, 2011
Ni coated SiO2 and SiO2 coated Ni composite particles with core-shell structures were designed, prepared and their microwave absorption properties were characterized. The comparison study of the shell effect on the effective electromagnetic parameters reveals that the effective permittivity/permeability was crucially determined by the percent and the ...

Achieving High Damping Capacity in Oxygen‐Enhanced BCC Zr‐Hf‐Ti‐Nb Multi‐Principal‐Element Alloys with Low Young's Modulus

open access: yesAdvanced Science, EarlyView.
A series of oxygen‐enhanced Zr‐Hf‐Ti‐Nb MPEAs with high strength and outstanding damping capacity are developed through tailoring the BCC structural stability by an elaborate composition regulation. Strengthening mechanism for high strength and damping mechanism related to various Snoek‐type relaxations reveals that the existence of multiple separate O‐

Mesoporous Gold Nanospheres Confined Platinum Nanoclusters as Robust ROS and Oxygen Nanogenerators for NIR‐II Hyperthermia Cancer Therapy

open access: yesAdvanced Science, EarlyView.
Mesoporous gold nanospheres confined platinum nanoclusters (MGNSs@Pt) is developed as robust hydroxyl radical and oxygen nanogenerators for multimodal therapies. Their NIR‐II LSPR property also allowed MGSNs to be ideal phototheranostic agents. The chemodynamic and photothermal therapy efficiently induced the tumor cell apoptosis, enabling the MGNSs@Pt

Phosphorus Vacancy‐Induced Built‐In Electric Field for Electromagnetic Properties Modulation

open access: yesAdvanced Science, EarlyView.
The advantages of defect‐induced polarization resulting from group VA anion vacancies, particularly phosphorus vacancies (VP) are analyzed in comparison to the anion vacancies of other elements. P atoms possess both plentiful high‐energy unpaired valence electrons in 3p orbitals and moderate nonmetallicity, thus the selection of VP for regulating EM ...
