Spin-Crossover Modification through Selective CO2 Sorption
2013
[EN] We present a spin-crossover Fe-II coordination polymer with no permanent channels that selectively sorbs CO2 over N-2. The one-dimensional chains display internal voids of similar to 9 angstrom diameter, each being capable to accept one molecule of CO2 at 1 bar and 273 K. X-ray diffraction provides direct structural evidence of the location of the gas molecules and reveals the formation of O=C=O(delta(-))center dot center dot center dot pi interactions. This physisorption modifies the spin transition, producing a 9 K increase in T-1/2.
Patterning of Magnetic Bimetallic Coordination Nanoparticles of Prussian Blue Derivatives by the Langmuir–Blodgett Technique
2012
We report a novel method to prepare patterns of nanoparticles over large areas of the substrate. This method is based on the adsorption of the negatively charged nanoparticles dispersed in an aqueous subphase onto a monolayer of the phospholipid dipalmitoyl-l-α-phosphatidylcholine (DPPC) at the air-water interface. It has been used to prepare patterns of nanoparticles of Prussian blue analogues (PBA) of different size (K(0.25)Ni[Fe(CN)(6)](0.75) (NiFe), K(0.25)Ni[Cr(CN)(6)](0.75) (NiCr), K(0.25)Ni[Co(CN)(6)](0.75) (NiCo), Cs(0.4)Co[Cr(CN)(6)](0.8) (CsCoCr), and Cs(0.4)Co[Fe(CN)(6)](0.9) (CsCoFe)). The behavior of DPPC monolayer at the air-water interface in the presence of the subphase of P…
Photocatalytic oxidation of acetonitrile in gas–solid and liquid–solid regimes
2005
Il programma NON mi ha consentito di scaricare il PDF di questo articolo. Se lo volete ditemi come inviarlo ABSTRACT Photocatalytic degradation of acetonitrile was carried out in both gas–solid and liquid–solid regimes using two commercial TiO2 catalysts (Merck and Degussa P25). For the gas–solid regime, a continuous annular photoreactor was used. The influence on photodegradation kinetics of the gas flow rate and concentrations of acetonitrile, oxygen, and water was investigated. Acetonitrile degradation products detected in the gas phase included carbon dioxide and hydrogen cyanide. The same photoactivity was exhibited in the presence and in the absence of water vapour. The liquid–solid reg…
El efecto moderador de la edad en la relación entre el valor percibido, las TIC del minorista y la lealtad del cliente
2010
AbstractInformation and communication technology (ICT) may represent a source of benefits for retailers. However, there is a debate in the literature on how ICT influences customer-supplier relationships. In addition, the evidence on the effect of age on consumer attitudes towards retail technological solutions is not conclusive. This paper proposes and tests a model to analyze the influence of retail ICT on consumer loyalty towards the retailer, as well as to assess the moderating role of consumer age on this relationship. As a result, customer assessment of retail ICT, together with perceived value, exerts a positive influence on consumer commitment and satisfaction, being the latter an a…
Fastlegers informasjonsbehov ved medisinsk avstandsoppfølging : En kvalitativ studie
2019
Masteroppgave helse- og sosialinformatikk HSI500 - Universitetet i Agder 2019 Bakgrunn:For å møte den fremtidige økningen i forekomsten av ikke-smittsomme kroniske sykdommerhar Norge prøvd utmedisinsk avstandsoppfølging siden2016. Resultatene så langt viser en økt trygghet, samt følelse av oppfølging og kontroll over egen helse hos pasientene. Det understrekes at det å involvere fastleger i tjenestene har vært utfordrende(Helsedirektoratet, 2018a). Videreutprøvingble startet opp i 2018 og er planlagt å fortsette til og med2021. Hensikt:Formålet med denne masteroppgaven er å bidra med kunnskap om hvordan IKT best mulig kan understøtte fastlegenes tiltenkte rolle som koordinator i medisinsk a…
Increased electron donor and electron acceptor characters enhance the adhesion between oil droplets and cells of Yarrowia lipolytica as evaluated by …
2003
The adhesion of methyl ricinoleate droplets to cells of the yeast Yarrowia lipolytica was investigated. A new cytometric method, relying on the double staining of fatty globules with Nile Red and of cells with Calcofluor, enabled us to quantify methyl ricinoleate droplet adhesion to cells precultured on a hydrophilic or on a hydrophobic carbon source. In this last case, droplet adsorption was enhanced and a MATS (microbial adhesion to solvents) test revealed that this increase was due to Lewis acid-base interactions and not to an increase in the hydrophobic properties of the cell surface. These preliminary results demonstrate that the developed cytometric method is promising for various app…
Experimental studies on carbon nanotubes and graphene functionalized via physical adsorption with cellulose and avidin
2018
In this Thesis I have experimentally studied structural, electronic, and optical properties of hybrids of nanocarbon materials, carbon nanotubes (CNT) and graphene, and certain biomacromolecules. The latter are especially xylan, a type of hemicellulose, and avidin, an important protein. Complexes of CNT with hemicellulose are attractive because the hybrid material is soluble in water. The conductive transport properties of thin films of CNT /hemicellulose have been systematically studied with different experimental tools. These are low temperature DC conduction measurements, Kelvin probe microscopy, and optical conductivity measurements at terahertz frequencies. The results clearly indicate …
Computer Vision Interaction for People with Severe Movement Restrictions
2006
In this paper we present the starting point of research in applying humancomputer interaction (HCI) techniques to help people with cerebral palsy to use computers via vision-based interaction. Our work includes the development and improvement of visionbased assistive technology, which was tested in experiments with cerebral palsy users. A brief review of current assistive technologies for severely physically impaired people and an explanation of the developed applications of such technologies are also presented. The final part of the paper describes the experimentation goals, process, and preliminary results. Future work directions are also indicated.
