Bioresorbable and Wireless Rechargeable Implanted Na‐ion Battery for Temporary Medical Devices

Advanced Functional Materials, EarlyView.
An all‐solid‐state bioresorbable Na‐ion battery is developed, composed entirely of bio‐eliminable materials. In vivo and ex vivo tests confirmed harmless disintegration of this implanted battery. Lifetime of the implanted battery can be precisely controlled by adjusting the dissolvable encapsulation layer's thickness.

Extended scenarios for solar radio emissions with downshifted electron beam plasma excitations [PDF]

First-principle studies of radiative processes aimed at explaining the origin of type II and type III solar radio bursts raise questions on the implications of downshifted electron beam plasma excitations with frequency (slightly) below the plasma frequency ($\omega\lesssim\omega_{pe}$) in the generation of radio emissions.

Multi-Band Propagation and Radio Channel Characterization in Street Canyon Scenarios for 5G and Beyond

IEEE Access, 2019
Radio access at mm-waves has been subject of intensive research in the latest years. However, within the initial deployment of 5G, mm-waves are still relegated and there is a generalized idea that the mm-wave channel for radio access, in comparison to ...

Concurrent Interface Passivation and Contact Work Function Tuning in Organic Self‐Aligned Gate Transistors and Complementary Circuits Using Phosphonic Acid Self‐Assembled Monolayers

Advanced Functional Materials, EarlyView.
Self‐aligned gate transistors are developed with a single‐step dielectric passivation and fine‐tuning of source/drain electrode work function using phosphonic acid self‐assembled monolayers (SAM). This transistor architecture minimizes overlap capacitances and access resistance.

3D In Vitro Glioma‐Neuron‐Astrocyte Biomimetic Composites Recapitulate Key Molecular Mechanisms Linked to Glioblastoma Multiforme Pathophysiology

Advanced Functional Materials, EarlyView.
Glioblastoma multiforme is the most devastating and incurable brain tumor. To better study this disease, a 3D model is developed using a hyaluronic acid‐based hydrogel combined with a multicellular approach. This model recapitulates in vivo brain stiffness, cell‐extracellular matrix and cell‐cell interactions and the tumor's hijacking function with the
