Effect of alkanethiol self-assembled monolayers on the plastic and elastic deformation of gold (111) films

Surface chemistry is known to affect the elastic deformation of nanocontacts, but its role in plastic deformation is less clear. Alkanethiol self-assembled monolayers (SAMs) were used to modify the surface energy and surface stress of Au(111) films. The chemical effect of this nanometer scale film on elastic and plastic deformation was investigated using nanoindentation combined with atomic force microscopy (AFM) imaging of indents. A range of maximum indentation displacements and SAM chain lengths were used. Comparisons were made between the mechanical response of the gold substrate alone and the gold modified with the different SAMs. The nanoindentation load-displacement curves and the mechanical properties were found to be dependent on the presence of the SAM. A decrease in the reduced elastic modulus was observed when indenting the SAM systems. The work of indentation and the hardness showed a similar effect with the SAM layer lowering hardness in both cases. Remarkably, the SAM was found to affect hardness, and hence plasticity, at indentation depths over 100 times the SAM thickness. Comparisons were made between the projected contact areas approximated using the Oliver and Pharr method with the actual areas directly measured by AFM analysis. This accounts for underestimation of the contact area due to pileup of gold around the indent. AFM characterization of the residual nanoindentation impressions showed substantial differences between the indent shape and pileup when comparing the gold to the gold plus SAM surfaces. The differences are more pronounced for the longer chain length SAM and as the indents become deeper. The SAM reduces the adhesion force between the indenter tip and surface which may affect the observed mechanical properties for shallow indents. For the deeper indentations the exothermic reaction of the alkanethiol molecules chemisorbed on the gold surface reduces the surface free energy of the gold substrate which favors the creation of new surface (pileup). In addition, surface stress which is compressive when a SAM is present, but tensile otherwise, appears to modify the behavior of dislocations and strain hardening in the Au films. This is the most likely cause of the dramatic change in hardness and pileup.Ph.D.Includes abstractVitaIncludes bibliographical referencesby Milca I. Apont

Synthesis and characterization of tin oxide microfibres electrospun from a simple precursor solution

Tin oxide (SnO2) microfibres in the rutile structure were synthesized using electrospinning and metallorganic decomposition techniques. Fibres were electrospun from a precursor solution containing 20 mg poly(ethylene oxide) (molecular weight 900 000), 2 ml chloroform and 1 ml dimethyldineodecanoate tin, and sintered in the air for 2 h at 400, 600 and 800 \ufffdC, respectively. Scanning electron microscopy, x-ray diffraction and Raman microspectrometry were used to characterize the sintered fibres. The results showed that the synthesized fibres are composed of SnO2.NRC publication: Ye

Synthesis and Characterization of Ultra-Fine Tin Oxide Fibers Using Electrospinning

Ultrafine tin oxide (SnO2) fibers having a rutile structure, with diameter ranging from 100 nm to several micrometers, were synthesized using electrospinning and metallorganic decomposition techniques. In this work, we propose a precursor solution that is a mixture of pure SnO2 sol made from SnCl4:H2O:C3H7OH:2-C3H7OH at a molar ratio of 1:9:9:6, and a viscous solution made from poly(ethylene oxide) (PEO) (molecular weight 900?000) and chloroform (CHCl3) at a ratio of 200 mg PEO/10 mL CHCl3. This solution allows to obtain an appropriate viscosity for the electrospinning process. The as-deposited fibers were sintered at 400?, 500?, 600?, 700?, and 800?C in air for 2 h. Scanning electron microscopy, scanning probe microscopy, X-ray diffraction, Raman microspectrometry, and X-ray photoelectron spectroscopy (XPS) were used to characterize the sintered fibers and elucidate the chemical reaction during sintering. The results showed that up to the sintering temperature of 700?C, the synthesized fibers are composed of SnO2. XPS was found to reflect the complicate chemical changes caused by the sintering process.Peer reviewed: YesNRC publication: N

How big data is used as a key element for hybrid university education

Hybrid learning in universities is the blending and mixing of the learning environments, this includes both face-to-face (FTF) which implies classroom instruction and online environment (E-learning)  as well. According to De Mauro, Greco and Grimaldi (2016), Ellis’ study shows that hybrid learning provides the students with the opportunity to understand and explore the real world at the same time through various authentic experiences. Authentic experience as cited by De Mauro, Greco and Grimaldi (2016) can be facilitated in the online learning environment through coming up with sufficient online learning or by blending learning to combine both online and FTF learning. The main objective of hybrid learning is to enhance effective and efficient experience through a more improved delivery model. This study is based on the review of previous articles using PRISMA methodology, it focuses on the big data as key element in hybrid learning in university education. The main objective of this study is to review 40 articles published in Scopus within 2010 to 2022 subject to big data in education, hybrid learning in universities or higher learning institutions and based on their findings the study come up with a conclusion  as discussed below
