Soft and Transient Bioelectronics Enabled by Polymer‐Free Ti3C2Tx MXene Hydrogels

open access: yesAdvanced Materials, EarlyView.
We present Ti3C2Tx MXene hydrogel (MXgel) bioelectronics, a soft, flexible, and fully transient platform for high‐fidelity neural recording and stimulation. MXgel bioelectronics exhibit exceptional electrical conductivities, low electrochemical impedances, and high charge injection capacities.

Multi‐Li+ Coordination for Superior Room‐Temperature Ionic Conductivity in PEO Solid Electrolytes

open access: yesAdvanced Materials, EarlyView.
A phosphonate‐functionalized polycarboxylate ether (P‐PCE) is introduced into PEO electrolytes to induce multi‐Li+ ions coordination, which effectively dissociates lithium salts, liberates Li+ from the strong chelation by PEO chains, and promotes fast Li+ hopping between adjacent coordination sites. Simultaneously, this design establishes dynamic, high‐

Pervasive Technologies and Support for Independent Living

open access: yes
A broad range of pervasive technologies are used in many domains, including healthcare: however, there appears to be little work examining the role of such technologies in the home, or the different wants and needs of elderly users.

Charge‐Reversed Lipid Nanoparticles Enable Encapsulation of Pt2L4 Nanocages for In vivo Anti‐Cancer Treatment

open access: yesAdvanced Materials, EarlyView.
Charge‐reversed lipid nanoparticles (revLNPs) enable efficient encapsulation and delivery of cationic Pt2L4 nanocages. Encapsulation preserves potent anticancer activity while improving circulation, reducing vascular leakage, and promoting favorable biodistribution in vivo.

Bacteria‐Trained, MnO2‐Armored Dendritic Cells for Immunotherapy

open access: yesAdvanced Materials, EarlyView.
MnO2‐armored, bacteria‐trained dendritic cells undergo tumor‐responsive mechanical and immunological transformation. The nanocoating masks immune ligands and maintains a mechanically stiff, quiescent state during circulation, while the tumor microenvironment removes the armor and restores cellular deformability and immune accessibility.

Biomass DNA: An Emerging Building Block for Advanced Materials

open access: yesAdvanced Materials, EarlyView.
Biomass DNA is rapidly emerging from its traditional role as a genetic blueprint to serve as a versatile abundant, highly programmable polymeric building block. This review highlights the transformation of macroscopic bulk biomass DNA into next generation of functional materials, spanning from dynamic hydrogels, sustainable bioplastics, and high ...

Adaptive Supramolecular Interactions Govern Redox‐Active Molecules in Aqueous Redox Flow Batteries

open access: yesAdvanced Materials, EarlyView.
Adaptive supramolecular interactions overcome the solubility‐stability trade‐off in aqueous redox flow batteries. Hydrophobic anions disrupt intrinsic π–π stacking to enable high solubility, while redox‐state‐dependent spin pairing and cation coordination dynamically stabilize reactive intermediates during operation.

Rate Loss Analysis of Reconfigurable Intelligent Surface-Aided NOMA With Limited Feedback

open access: yesIEEE Open Journal of the Communications Society
The design of feedback channels in frequency division duplex (FDD) systems is a major challenge because of the limited available feedback bits. We consider non-orthogonal multiple access (NOMA) systems that incorporate reconfigurable intelligent surfaces

Near‐Infrared Imaging of H2O2 in Plants With Nanosensors Under Environmentally Changing Conditions

open access: yesAdvanced Materials, EarlyView.
This paper reports a ratiometric nanosensor enabling robust, multivariate detection of stress signals (H2O2) in plants, with high resistance to light fluctuations and mechanical disturbances. Single‐walled carbon nanotubes serve as the sensor, Egyptian Blue nanosheets serve as a stable reference, and plant autofluorescence serves as a label‐free ...
