Development of biocompatible parylene neurocages [PDF]

open access: yes, 2004
We present a refined method and design for building parylene neurocages for in vitro studies of live neural networks. Parylene neurocages are biocompatible and very robust, making them ideally suited for studying the synaptic connections between ...

Direct Patterning of a Cyclotriveratrylene Derivative for Directed Self-assembly of C60 [PDF]

open access: yes, 2011
A novel apex-modified cyclotriveratrylene (CTV) derivative with an attached thiolane-containing lipoic acid linker was directly patterned onto gold substrates via dip-pen nanolithography (DPN).

Characterization and Antimicrobial Activity of Hafnium Nanostructures Fabricated by Physical Vapor Deposition Through a Colloidal Mask

open access: yesAdvanced Materials Interfaces, EarlyView.
We generate hafnium nanostructures by first depositing polystyrene particles of varying diameter followed by physical vapour deposition of hafnium thin films. The resultant structure shows a kill‐on‐contact effect against both Gram‐negative Escherichia coli and Gram‐positive Staphylococcus aureus.

Surface characterization data for tethered polyacrylic acid layers synthesized on polysulfone surfaces. [PDF]

open access: yes, 2019
The data presented are supplementary to an article [Kim et al., 2019] on synthesis and surface characterization of tethered polyacrylic acid (PAA) layers on polysulfone (PSf) film/membrane surfaces via atmospheric pressure plasma-induced graft ...

High‐Performance, Paper‐Based Microelectronics via a Micromodular Fabrication Process

open access: yesAdvanced Materials Interfaces, EarlyView.
This study demonstrates high‐performance silicon micromodular transistors on cellulose nanomaterial‐coated paper, with interconnects formed via e‐jet printing. Transistors exhibit excellent electrical properties and maintain performance under applied strain.

Determination and evaluation of mercury concentration in fish in the São Francisco River Watershed, Brazil

open access: yesRevista Ambiente & Água, 2021
The objective of this work was to evaluate the bioaccumulation of mercury in 13 species of fish with different eating habits, captured in the Três Marias Reservoir, São Francisco Basin, from March 2012 to April 2013.

Analytical perturbative theories of motion in highly inhomogeneous gravitational fields : Ariadna AO/1-6790/11/NL/CBI [PDF]

open access: yes, 2012
In this report we show that modern computer performances and state-of-the-art algebraic manipulator software are sufficiently developed to carry out our generalised analytical perturbative theory.

Surface-induced charge state conversion of nitrogen-vacancy defects in nanodiamonds

open access: yes, 2010
We present a study of the charge state conversion of single nitrogen-vacancy (NV) defects hosted in nanodiamonds (NDs). We first show that the proportion of negatively-charged NV$^{-}$ defects, with respect to its neutral counterpart NV$^{0}$, decreases ...

Passivated SiC Surfaces for Photonic and Quantum Applications: Balancing Chemical Stability and Surface Luminescence

open access: yesAdvanced Materials Interfaces, EarlyView.
Low‐temperature passivation of SiC reveals that optical surface quality and chemical stability are not directly correlated. Ar plasma‐treated and SiNx‐passivated surfaces yield the lowest photoluminescence background, whereas CF4 plasma and ALD‐grown dielectrics introduce higher emission.

Agra, arboreal beetles of Neotropical forests: pusilla group and piranha group systematics and notes on their ways of life (Coleoptera, Carabidae, Lebiini, Agrina)

open access: yesZooKeys, 2010
Revisions of two new species groups of the genus Agra Fabricius are presented with the following species described as new: pusilla group - Agra cruciaria sp. n. (Brazil), Agra grace sp. n. (Ecuador, Perú), Agra max sp. n.
