Robust fringe pattern analysis method for transient phenomena
(Elsevier, 2018)"We propose a method for analysing a sequence of noisy interferograms with closed fringes acquired at a high–speed frame rate. Our method is appropriate for analysing ESPI sequences of transient phenomena such as deformations ... -
Stabilisation of small mono- and bimetallic gold–silver nanoparticles using calix[8]arene derivatives
(Royal Society of Chemistry, 2018)"In this paper, we report the synthesis of octa(hydroxy)-octa(mercaptobutoxy)calix[8]arene and its use as a stabiliser of nanoparticles (NPs). We show that the reduction of gold and/or silver ions in the presence of this ... -
Viscosity and normal stress forces of Lennard-Jones chains using reverse non-equilibrium molecular dynamics
(Taylor & Francis, 2017)"Reverse non-equilibrium molecular dynamics was applied for the calculation of the viscosity for different chain lengths. Each chain consisted of m tangent spherical sites, where m was 1, 2, 4, 8 or 16, respectively. From ... -
Shape-anisotropic nickel-PDMS composites with uniaxial magnetic anisotropy obtained by emulsification under magnetic field
(Springer, 2017)"Magnetic microcomposites were fabricated by emulsification of a mixture of polydimethylsiloxane (PDMS) and nickel microparticles. The composites were obtained in a temperature-controlled water-surfactant media with and ... -
Surface modification of TiO2 with Ag nanoparticles and CuO nanoclusters for application in photocatalysis
(American Chemical Society, 2016)"Ag and CuO nanoparticles (NPs) synthesized on the surface of commercial TiO2 (P25) by radiolytic reduction were characterized by diffuse reflectance spectroscopy (DRS), transmission electron microscopy (TEM), high-angle ... -
Coexistence of two-photon absorption and saturable absorption in ion-implanted platinum nanoparticles in silica plates
(Optical Society of America, 2018)"Platinum nanoparticles were nucleated in a high-purity silica matrix by an ion-implantation method. The third-order nonlinear optical response of the samples was studied using femtosecond pulses at 800 nm with the z-scan ... -
Characterization of the kinetic arrest of martensitic transformation in Ni45Co5Mn36.8In13.2 melt-spun ribbons
