Blockchain‐Empowered H‐CPS Architecture for Smart Agriculture

open access: yesAdvanced Science, EarlyView.
This article reviews the current system architectures for smart agriculture and proposes a blockchain‐empowered hierarchical cyber‐physical system (H‐CPS) framework. It discusses the challenges and outlines future research directions, including the use of semantic blockchain to handle complex data and models.

“Confined Eutectic” Strategy for Visual Refrigeration Responsive Fluorescent Materials with Easy Preparation and Multi‐Color Tunability

open access: yesAdvanced Science, EarlyView.
A new strategy of “confined eutectic” is proposed to achieve fluorochromic materials that can readout refrigeration temperature with naked‐eye. It leverages changes in the crystallinity of the confined eutectics in nano/micro‐domains to regulate the aggregation and dispersion states of fluorophores.

m6A‐Mediated TMCO3 Promotes Hepatocellular Carcinoma Progression by Facilitating the Membrane Translocation and Activation of AKT

open access: yesAdvanced Science, EarlyView.
TMCO3 as a downstream target of ALKBH5 is found, which regulates its expression in an m6A‐dependent manner, and then a new phosphorylation site on TMCO3 is identified and determines the specific mechanism of TMCO3 with AKT. Moreover, the combined treatment of targeting the TMCO3 and inhibition of AKT in mice models with HCC achieves great results ...

Impact of Transition Metals and Electrocatalyst Layer Thickness on the Pt‐Based Cathodes of Proton Exchange Membrane Fuel Cells – Do Multimetallic Electrocatalysts Necessarily Yield an Improved Performance?

open access: yesAdvanced Energy Materials, EarlyView.
Nonnoble transition‐metals (TMs) in PtCuNi/C catalysts have a dual influence in proton‐exchange membrane fuel cell cathode catalyst layer. While TMs act as a “sacrificial component” of PtCuNi/C, inhibiting Pt dissolution from the PtMx nanoparticles bearing the active sites, they promote the formation of separate catalysts and ionomer domains in the ...
