Systematic Benchmarking of a Noise‐Tolerant Conductive Hydrogel Electrode for Epidermal Bioelectronics

open access: yesAdvanced Science, EarlyView.
General schematic of the approach. Abstract Conventional Silver/Silver Chloride (Ag/AgCl) electrodes remain the clinical standard for electrophysiological monitoring but are hindered by poor skin conformity, mechanical rigidity, and signal degradation, particularly under motion or sweat.

Unraveling Energy Flow Mechanisms in Semiconductors by Ultrafast Spectroscopy: Germanium as a Case Study

open access: yesAdvanced Science, EarlyView.
A multi‐technique pump‐probe setup capable of performing both transient reflectivity and time‐resolved Raman spectroscopy after ultrafast excitation, provides a comprehensive understanding of ultrafast electronic and phononic processes. Distinct decay rates for the temperature, frequency, and linewidth of the phonon mode in germanium are observed ...

Wireless Bioelectronic Modulation of Membrane Potential in Glioblastoma Using Carbon Nanotube Porins

open access: yesAdvanced Science, EarlyView.
A schematic illustrating glioblastoma cell membrane modulation using carbon nanotube porins (CNTPs) and an applied voltage. CNTPs enable ion flux leading to changes in membrane potential. This figure summarizes the concept of bioelectronic control of cell membrane voltage.

Free‐Volume Regulation Enables Significantly Enhanced Electrical Breakdown via Short‐Chain Molecular Spatial‐Positioning Intercalation into Poly(vinylidene fluoride)

open access: yesAdvanced Science, EarlyView.
An innovative molecular spatial‐positioning shimming strategy is developed to optimize the electrical properties of poly(vinylidene fluoride) (PVDF). By intercalating polyethylene wax (PE wax) short‐chain molecules into PVDF's free volume, the film achieves a significantly enhanced energy density of 32.67 J cm−3.

3D‐MOF‐Lattice Inspired Programmable Metamaterials Based on Reconfigurable Polyhedral Origami

open access: yesAdvanced Science, EarlyView.
A novel metamaterial design strategy: inspired by MOFs crystal networks, creating reconfigurable modular polyhedral units to overcome the limitations of traditional materials. These modules exhibit adjustable stiffness, bistability, and Poisson's ratio that can be adjusted from negative to positive values.

Design of power oscillation damping controllers for renewable power plants

open access: yesTesla Innovation Days (2024, Belgrade) - zbornik radova
Converter-interfaced generation (CIG) has been used to transfer energy from solar irradiation and wind to electricity networks. Until now, power plants based on CIG have been used solely to inject power from the primary source whenever it is available. As the share of CIG increases, its impact on the power system operation has become more relevant with
