Challenges and Opportunities in Combining Ultrasound and Inductive Coupling for Energy Supply and Bidirectional Data Exchange in Bioelectronics Medicine Implant Networks

open access: yesAdvanced Intelligent Systems, EarlyView.
In this contribution, it is shown that miniaturized nerve stimulation implants can be used in collaborative networks. Inductive links and ultrasound are combined to supply these implants with energy and data; the advantages and disadvantages of each method, as well as safety risks and possibilities for improvement are discussed and the best ...

Next Generation Modeling of Glioblastoma Progression: Diffusing Through Time and Brain

open access: yesAnnalen der Physik, EarlyView.
Glioblastoma (GBM) is a fatal brain tumor that will inevitably recur following surgical resection. Early mathematical tumor growth models used the reaction‐diffusion equation to describe the proliferation and invasion of tumor spread. However, with increasingly advanced neuroimaging technology, diffusion tensor imaging data has more recently been ...

Recycling of Polymer Components From Waste Face Masks for Asphalt Modification: A Mini Review

open access: yesJournal of Applied Polymer Science, EarlyView.
ABSTRACT The COVID‐19 pandemic greatly increased plastic waste through widespread personal protective equipment (PPE) use, creating a serious environmental challenge. Disposable face masks (FM), primarily composed of non‐biodegradable polypropylene, account for an estimated 86 million units discarded monthly, leading to significant environmental ...

Structure of the Multiphase Chalcolithic Tell Chiselet–Grădiștea Fundeanca (Romania) From SH‐Wave Full‐Waveform Inversion, Borehole Geophysics and Coring

open access: yesArchaeological Prospection, EarlyView.
ABSTRACT The emergence and development of settlement mounds, also called tells, is of major interest for the analysis of socio‐economic transformations occurring in the lower Danube plain during the East European Chalcolithic period. In this context, the multiphase chronology and structural layout of tells are highly relevant indicators, but small ...

Elemental Analysis of Catalysts in a Fixed‐Bed Reactor by Laser‐Induced Breakdown Spectroscopy

open access: yesChemCatChem, EarlyView.
The “Elemental Composition” provides information about promoters and poisons found in heterogeneous catalysts. Access to this piece of information under reaction conditions remains yet an unsolved challenge. This work explores the potential and limitations of laser‐induced breakdown spectroscopy (LIBS) as an in situ reactor diagnostic technique ...
