Resonant spike propagation in coupled neurons with subthreshold activity

open access: yes, 2008
Màster en Biofísica, curs 2006-2007Chemical coupling between neurons is only active when the presynaptic neuron is firing, and thus it does not allow for the propagation of subthreshold activity.

Advances and Perspectives in Graphene‐Based Quantum Dots Enabled Neuromorphic Devices

open access: yesAdvanced Science, EarlyView.
Graphene‐based QDs are zero‐dimensional carbon nanomaterials with pronounced quantum confinement and tunable electronic structures. Herein, we summarize their synthesis strategies and functionalization methods, and highlight their functional roles and operating mechanisms in devices, as well as recent advances in neuromorphic electronics. We anticipate

Sustainable Synaptic Device with Two‐Dimensional Ferroelectric Materials for Neuromorphic Computing

open access: yesAdvanced Science, EarlyView.
α‐In2Se3 based FeSFETs can be utilized as sustainable devices through polarization switching governed by both out‐of‐plane and in‐plane polarizations. Upon reaching a fatigued state, current annealing enabled by conductance modulation can significantly enhance the endurance of FeSFETs.

Binding by asynchrony: the neuronal phase code

open access: yesFrontiers in Neuroscience, 2010
Neurons display continuous subthreshold oscillations and discrete action potentials. When action potentials are phase-locked to the subthreshold oscillation, we hypothesize they represent two types of information: the presence/absence of a sensory ...

Analysis of the total 12C(α,γ)16O cross section based on available angular distributions and other primary data [PDF]

open access: yes, 1996
Because a knowledge of the 12C/16O ratio is crucial to the understanding of the later evolution of massive stars, new R- and K-matrix fits have been completed using the available angular distribution data from radiative α capture and elastic α scattering

Versatile DNA‐Functionalized Biohybrid Hydrogel Platforms for Electrothermally Activated On‐Demand Payload Release

open access: yesAdvanced Science, EarlyView.
A DNA‐functionalized biohybrid hydrogel is developed by integrating Cu‐mediated nucleic acid microflowers into a thermoresponsive matrix, enabling electrothermally triggered, on‐demand payload release. The platform offers spatiotemporally controllable therapeutic delivery with promising applications in precision oncology, neural regulation, and chronic

Optimizing Metal‐Perovskite Interfaces: Electronic and Transport Properties of Au‐Bromide Perovskites Contacts

open access: yesAdvanced Electronic Materials, EarlyView.
This study examines metal–perovskite interfaces in 2D (BA)2PbBr4 and (PEA)2PbBr4 using first‐principles and NEGF methods. It compares top‐ and edge‐contact configurations, revealing Schottky barriers in top contacts and ohmic behavior in edge contacts.

Twisted MoS2 Bilayers as Functional Elements in Memtransistors: Hysteresis, Optical Signatures, and Photocurrent Kinetics

open access: yesAdvanced Electronic Materials, EarlyView.
ABSTRACT Layered 2D materials are considered as promising for memristive applications due to their ultimate vertical scalability compared to conventional semiconductor films and pronounced hysteresis properties. Bias‐resolved Raman and Photoluminescence mapping is used to quantify strain from phonon shifts and carrier density from the exciton‐trion ...

Toward Stable and High‐Performance Metal Halide Perovskite Field‐Effect Transistors

open access: yesAdvanced Electronic Materials, EarlyView.
This ToC illustrates the evolution from unstable 3D perovskites with ion migration toward advanced 2D, mixed‐halide, and vacancy‐ordered structures, culminating in stable, high‐performance perovskite field‐effect transistors. ABSTRACT There is a critical need for high‐quality perovskite semiconductor films to enable highly stable field‐effect ...
