As previously reported the batch electrochemical cell was used with the electrodes of B type to separately determine the Catechol or Bisphenol A concentrations in aqueous solutions. In particular, with the B1, B2 and B3 electrodes we have studied the electrochemical response to BPA in the concentration range from 3 to…
We present a simple and versatile patterning procedure for the reli-able and reproducible fabrication of high-aspect-ratio (104) electri-cal interconnects that have separation distances down to 20 nm and lengths of several hundreds of microns. The process uses standard optical lithography techniques and allows paralle…
We calculate the dynamical conductivity of AA-stacked bilayer graphene as a function of frequency and in the presence of a finite chemical potential due to charging. Unlike the monolayer, we find a Drude absorption at charge neutrality in addition to an interband absorption with onset of twice the interlayer hopping e…
This chapter contains sections titled: Salts and Cocrystals: Supersaturating API Nanomilled API Particles Self-Emulsifying Drug Delivery Systems (Micelle/Emulsion Solubilization) Solid Dispersion Supersaturable Formulations Prodrugs to Increase Solubility Prodrugs to Increase Permeability Controlled Release Communicat…
We use the recently introduced nested sampling Monte Carlo algorithm to calculate the partition function of the three dimensional periodic hard sphere system. Given the partition function, we evaluate the compressibility and the free energy as functions of the packing fraction and local order, showing that the transit…
A powerful and flexible resource to discover the knowledge contained within more than 500,000 crystal structures.
Neste trabalho atomos de prata foram depositados por ion sputtering na superficie de dois tipos de resina epoxi diglicidil eter de bisfenol A (DGEBA). Os filmes de DGEBA e seus precursores foram caracterizados por espectroscopia Raman e infravermelha para identificas os principais grupos funcionais e suas relacoes com…
Gliomas are the most common brain tumor in adults, occurring in more than 50% of brain tumor cases.Astrocytomas, or tumors that arise from the astrocytes of the brain, account for 60-70% glioma cases. 1 The most common form of glioma is the grade IV astrocytoma known as glioblastoma multiforme. 2 The interactions betw…
In this chapter, we describe colloidal self-assembly pathways towards fabricating ultrahigh-density ordered nanostructures over large areas. Colloidal self-assembly directed by templates has been shown to enable the formation of controlled nanosphere arrays with periods well below 100 nm. We developed our nanopattern…
Metallic nanowire arrays having high optical transmission and electric conductivity show promise for use as transparent electrodes. Transparent electrodes require high transmission of visible light and good electrical conductivity for charge transfer. High-aspect-ratio metallic nanowires for transparent electrode appl…

We measured at 4.2 K the current-perpendicular-to-plane magnetoresistances of sputtered ferromagnetically coupled [Co(3 nm)/Ag(1.8 or 2.0 nm)]${}_{n}$Co(3 nm) multilayers with $n$ = 0--8 that were imbedded in the middle of symmetric, Py-based, double exchange-bias spin valves. The measurements yielded the parameter fo…
Argonne's Director Eric Isaacs talks about the laboratory's efforts for creating new, clean energy solutions.
This pamphlet focusses on two HSS activities that help ensure radiation exposures are accurately assessed and recorded, namely: 1) the quality and accuracy of occupational radiation exposure monitoring, and 2) the recording, reporting, analysis, and dissemination of the monitoring results. It is intended to provide a…
The time evolution of low energy spin states of a single molecular magnet in a local electric field is investigated. The decoherence of the driven single molecular magnet weakly coupled to a thermal bosonic environment is analyzed by the second-order time-convolutionless non-Markovian master equation. If the character…
This document outlines the basic conduct of operation (CONOPS) for a pedestrian radiation portal monitor (RPM), provided that the CONOPS is not facility or RPM specific and that it is based on a general understanding of a pedestrian RPM operation. The described CONOPS for a pedestrian RPM is defined by: (1) RPM design…
Este estudo avaliou o efeito do jateamento de Al2O3 na resistência de união de uma liga de ouro e uma de cobalto-cromo a uma cerâmica, após serem submetidos ao ensaio de flexão de três pontos (ISO 9693). As hipóteses foram que o tipo de liga produza valores de resistência de união semelhantes e o jateamento de Al2O3 m…
Geckos are remarkable little creatures, clinging to almost any dry surface, and Alyssa Stark, from the University of Akron, USA, explains that they appear to be equally happy scampering through tropical rainforest canopies as they are in urban settings. ‘A lot of work is done on geckos that looks at the very small adh…
Este estudo teve o propósito de investigar a correlação entre as propriedades microdureza superficial e resistência à compressão de compósitos indiretos. Confeccionaram-se 25 cilindros de 5 marcas comerciais de compósitos (n=5) de dimensões 13 X 4 mm. Signum (Heraeus Kulzer), Solidex (Shofu Inc.), Resilab (Wilcos), Ad…
Abstract The aim of this study was to develop Au-Pt-Pd-Si alloys with metal-resin bonding properties optimized for dental restorations. The amount of silicon added ranged from 0.00-0.54 wt.%. The Au-Pt-Pd-Si alloys were manufactured using an arc melting furnace. They were homogenized at 800°C in air and cold rolled to…
