Efeitos da rugosidade superficial nas propriedades de passivação de monocamadas orgânicas automontadas

open access: yesQuímica Nova, 2014
Precise surface area is needed for accurate characterization of self-assembled monolayers (SAMs) on metallic surfaces. The aim of this manuscript was to emphasize that miscalculation of surface area is the major source of errors in SAM electrochemical ...

Engineering Intelligent Graphene Oxide‐Cellulose Membranes: Suppressing Thermal Runaway for a Safer Aqueous Zinc‐Ion Batteries

open access: yesAdvanced Functional Materials, EarlyView.
A novel thermos‐responsive hydroxypropyl cellulose/graphene oxide (HPC/GO) composite membrane is fabricated for reversible temperature‐gated ion transport in aqueous zinc‐ion batteries. Enabled by LCST‐driven structural transition, unimpeded ion diffusion at room temperature delivers high capacity, while elevated temperature suppresses transport; full ...

Electrochemical Detection of Nitrite Based on Difference of Surface Charge of Self-Assembled Monolayers

open access: yesInternational Journal of Electrochemical Science, 2014
In this work, we reported a simple and sensitive electrochemical method for nitrite detection via Griess reaction. Specifically, naphthylethylenediamine (NEA) was immobilized onto the gold electrode to form positively charged self-assembled monolayers ...

Chirality and Organization of Adsorbates Modify Surface Phonon Dynamics

open access: yesAdvanced Functional Materials, EarlyView.
Chirality and molecular organization are shown to influence surface phonon dynamics in gold films. Time‐resolved Joule heating measurements reveal that ordered homochiral monolayers increase the Debye temperature and disordered layers reduce it, while ordered racemic controls have no effect.

Self-assembled monolayers of thiolates on metals: A review article on sulfur-metal chemistry and surface structures

open access: yes, 2014
A review article on fundamental aspects of thiolate self-assembled monolayers (SAMs) on the (111) and (100) surfaces of the Cu and Ni groups is presented. In particular this work is focused on two important points that remain poorly understood in most of

Self‐Healing and Stretchable Synaptic Transistor

open access: yesAdvanced Functional Materials, EarlyView.
A self‐healing stretchable synaptic transistor (3S‐T) is realized using a p‐PVDF‐HFP‐DBP/PDMS‐MPU‐IU bilayer as gate insulator, where dipole‐dipole interaction enhances polarization to achieve a large memory window. Leveraging its neuronal biomimicry, the synaptic transistor demonstrates electrically compatibility with the biological brain. Furthermore,

Study of the ability of self-assembled N-vinylcarbazole monolayers to protect copper against corrosion [PDF]

open access: yesJournal of the Serbian Chemical Society, 2002
N-Vinylcarbazole (NVC) monolayers were self-assembled on copper surfaces. The electrochemical properties of the copper surfaces modified by NVC self-assembled monolayers (SAMs) were investigated using polarization and electrochemical impedance ...

The Floor‐Ceiling‐Chip, or 2 × 2D = Pseudo‐3D—Approaching 3D Cell Morphology and Organization between Two Opposing 2D Substrates with Cell‐Adhesive Protein Micropatterns

open access: yesAdvanced Healthcare Materials, EarlyView.
Here, we present a novel 3D cell patterning and culture platform. The “Floor‐Ceiling‐Chip” (FC‐Chip) consists of two opposing track‐etched membranes, creating a pseudo‐3D microenvironment for the cells in between. By providing the membranes with micropatterned cell‐adhesive islands of varying geometries and sizes, the FC‐Chip enables control over cell ...

Advanced 3D Platforms for Modeling CNS Neuroinflammation: Cell Integration, Techniques, and Challenges

open access: yesAdvanced Healthcare Materials, EarlyView.
This review summarizes the roles of key central nervous system cell types, the extracellular matrix, and the blood‐brain barrier in neuroinflammation, and their integration into diverse 3D culture systems. It examines major incorporation strategies, including direct co‐culture, hydrogel encapsulation, transwell migration assays, and bioprinting ...
