Surface modification of titanium by plasma nitriding
(2003) [Journal article]A systematic investigation was undertaken on commercially pure titanium submitted to plasma nitriding. Thirteen different sets of operational parameters (nitriding time, sample temperature and plasma atmosphere) were used. ... -
Surface morphology and repellency mechanism investigation of Salvinia molesta plant
(2019) [Journal article]Bionics is a versatile tool with a technological potential, which designers use to search for signs and clues about functional elements and mechanisms in nature that allow for the development of products. The purpose of ... -
Surface morphology of spray-dried nanoparticle-coated microparticles designed as an oral drug delivery system
(2008) [Journal article]This paper was devoted to studying the influence of coating material (nanocapsules or nanospheres), drug model (diclofenac, acid or salt) and method of preparation on the morphological characteristics of nanoparticle-coated ... -
Surface photometry and spectral analysis of Mk50 : a Seyfert 1 nucleus in an early type galaxy
(1991) [Journal article]We analyze Markarian 50 using V and I CCD frames and IPCS and CCD spectra, respectively, obtained in June 1985 (low state of activity) and May 1990 (high state), covering the range 3200 Å<λ<10 100 Å. The surface brightness ... -
Surface plastic flow of three-dimensional printed polylactic acid in the tribological study of surface patterned polymer
(2022) [Journal article]The potential of three-dimensional (3D) printing in polymer tribology is poorly explored. Material alignment and composition play vital roles in altering the friction and wear characteristics of 3D printed materials. In ... -
Surface processing to improve the fatigue strength of bainitic steels : an overview
(2019) [Journal article]Currently, one of the major challenges for automotive industries is to reduce the weight and energy consumption of vehicles by using stronger and advanced low-cost materials. Conventional solutions using quenched and ... -
Surface temperature patterns of Lagoa dos Patos, Brazil, using NOAA-AVHRR data : an annual cycle analysis
(2010) [Journal article]A processing chain for NOAA-AVHRR data can be used to retrieve lake surface water temperatures (LSWT) measurements based on a nonlinear sea surface temperature (NLSST) algorithm generally applied to open ocean conditions. ... -
Surface tensions and surface potentials of acid solutions
(2010) [Journal article]A theory is presented which allows us to quantitatively calculate the excess surface tension of acid solutions. The H+, in the form of hydronium ion, is found to be strongly adsorbed to the solution-air interface. To account ... -
Surface water and energy fluxes in South America : an integrated approach based on remote sensing and flux measurements
(2022) [Thesis]South America is a water-abundant continent, home to the world's largest river basins and rainforest, which plays a crucial role in providing moisture to other regions of the continent through evapotranspiration (𝐸𝑇). ... -
Surface water impacted by rural activities induces genetic toxicity related to recombinagenic events in vivo
(2016) [Journal article]This investigation assessed the interaction of surface water samples with DNA to quantitatively and qualitatively characterize their mutagenic and/or recombinagenic activity. Samples were obtained at three different sites ... -
Surface water resources of Santa Catarina state’s southern region : geochemical background of the coal mining territory
(2022) [Journal article]In the environmental reclaiming process, it is essential to distinguish between chemical elements concentrations that occur naturally in water resources (geochemical background), from those originated from anthropogenic ... -
