Bacterial contamination of the membranes used during guided bone regeneration directly influences outcome this procedure. In study, we analyzed early stages bacterial adhesion on two commercial dense polytetrafluoroethylene (d-PTFE) in order to identify microstructural features that led different strengths. The microstructure was investigated by X-ray diffraction (XRD), differential scanning calorimetry (DSC), and Fourier transform infrared (FTIR). surface properties were atomic force...
Klebsiella pneumoniae is an emerging multidrug-resistant pathogen that can contaminate hospital surfaces in the form of a biofilm which hard to remove with standard disinfectants. Because resistance conservative disinfectants, application new disinfection technologies becoming more frequent. Ozone gas has antimicrobial activity but there lack data on its action against K. biofilm. The aim this study was investigate effects and mechanisms gaseous ozone OXA-48-procuding A 24 h formed ceramic...
Abstract A recent systematic experimental characterisation of technological thin films, based on elaborated design experiments as well probe calibration and correction procedures, allowed for the first time determination nanoscale friction under concurrent influence several process parameters, comprising normal forces, sliding velocities, temperature, thus providing an indication intricate correlations induced by their interactions mutual effects. This created preconditions to undertake in...
Extracellular vesicles (EVs) are membranous structures in biofluids with enormous diagnostic/prognostic potential for application liquid biopsies. Any such downstream requires a detailed characterization of EV concentration, size and morphology. This study aimed to observe the native morphology EVs human cerebrospinal fluid after traumatic brain injury. Therefore, they were separated by gravity-driven size-exclusion chromatography (SEC) investigated atomic force microscopy (AFM) cryogenic...
The aim of this study was to explore whether changes in the salivary pH influence mechanical properties, surface roughness, and ion release from NiTi archwires with various coatings, discuss clinical significance findings. uncoated, rhodium-coated, nitrified wires were immersed into artificial saliva different values (4.8, 5.1, 5.5, 6.6). Released nickel titanium ions measured inductively coupled plasma-optical emission spectroscopy at end 28 days. Atomic force microscopy used measure...
This study describes a straightforward preparation of hybrid organic–inorganic thin films containing stable 'sandwich'-like structure two atomic layer deposited (ALD) ZnO layers separated by organosilane phase, which is built from single organic component (3-mercaptopropyl)trimethoxysilane (MPTMS). Grafting MPTMS on the first ALD was performed in solution and driven strong affinity terminal thiol functionality (-SH) towards ZnO. We demonstrate that under different reaction conditions, either...
Understanding how sequence modification, self-assembly, stereochemistry and affinity for zinc ions contribute to catalytic function of histidine-rich metal-dependent peptides.
A structured transdisciplinary method for the experimental determination of friction in nanometric domain is proposed this paper. The dependence nanoscale on multiple process parameters these scales, which comprise normal forces, sliding velocities, and temperature, was studied via lateral force microscopy approach. procedure used to characterize stiffness probes used, especially influence adhesion obtained results, thoroughly described. analyzed thin films were by using either atomic layer...
The integration of energy harvesting systems into sensing technologies can result in novel autonomous sensor nodes, characterized by significant simplification and mass reduction. use piezoelectric harvesters (PEHs), particularly cantilever form, is considered as one the most promising approaches aimed at collecting ubiquitous low-level kinetic energy. Due to random nature excitation environments, narrow PEH operating frequency bandwidth implies, however, need introduce up-conversion...
This article presents a review of glyph-based techniques for engineering visualization as well practical application the multivariate process. Two glyph techniques, Chernoff faces and star glyphs, uncommonly used in practice, are described, applied to selected data set, run through chosen optimization methods user evaluated. As an example how these function, set heat exchanger with microchannel coil is adopted visualization. The results acquired by related carried out response surface method...
Energija mora kao jedan od najmanje iskorištenih obnovljivih izvora energije zahtjeva više pažnje u znanstvenom i stručnom smislu. Ovaj rad daje sažeti pregled potencijala mora, te različitih vrsta principa rada uređaja za iskorištavanje valova kojoj je sadržana najveća količina neiskorištenog mora.
Ovaj rad daje sažeti pregled korištenja solarne energije u RH poglavito priobalnom području. Izneseno je sadašnje stanje eksploatacije energije, te buduće projekcije ovog obnovljivog izvora energije.
