Electrochemical Ionic Synapses: Progress and Perspectives

Advanced Materials, Volume 35, Issue 37, September 14, 2023., 2023
Electrochemical ionic synapses (EISs) are programmable resistors whose conductivity is controlled deterministically by electrochemical charge insertion. Their repeatable conductance modulation and low energy consumption render them promising for enabling analog deep learning architectures with uncompromised accuracy and superior energy efficiency. Here,

3D bioprinting microgels to construct implantable vascular tissue

Cell Proliferation, Volume 56, Issue 5, May 2023., 2023
The synergy of strength and biocompatibility in one matrix is essential to meet angiogenic HUVEC‐based sprouting and bear shear stress for implanting tissue engineering for clinical applications at a large scale. Here, the authors demonstrate a design strategy of microgel reinforced cell‐laden matrix with heterogeneous stiffness for constructing ...

Structure and properties of cerium phosphate and silicophosphate glasses

Journal of the American Ceramic Society, Volume 106, Issue 5, Page 2808-2819, May 2023., 2023
Abstract We report on the fabrication, properties, and structure of cerium pyrophosphate glasses and partially substituted cerium silicophosphates. In those glasses, cerium occurs predominantly as Ce(III). A combination of dynamic nuclear magnetic resonance and electrical impedance spectroscopy is used to overcome the problem of assessing cerium ...

Spectral Tuning, Stabilities under External Exposures, and Spontaneous Enhancement of Emission Intensity in Grown‐into‐Glass All‐Inorganic Metal Halide Perovskite Nanocrystals

Laser &Photonics Reviews, Volume 17, Issue 1, January 2023., 2023
The grown‐into‐glass all‐inorganic metal halide perovskite CsPbBr3:Ln3+ nanocrystals not only feature a blueshift of emission position with a substitution of Pb2+ sites with Ln3+ ions but also show improved photoluminescent properties and a spontaneous enhancement of 20–25% of emission intensity as compared to bulk CsPbBr3.
