We investigated the morphology of polyethylene films by the Differential Evanescent Light Intensity (DELI) imaging method developed by us previously. The films were prepared by the Matrix Assisted Pulsed Laser Evaporation (MAPLE) technique. Rough or smooth organic layers were fabricated with thickness depending on the deposition conditions. We used the DELI imaging method here as a fast, low cost method for surface morphology diagnostics of large

Thin films morphology investigation of polyethylene by the differential evanescent light intensity (DELI) imaging method has been performed. The films of nanometer thickness were obtained by the matrix-assisted pulsed laser evaporation (MAPLE) technique. MAPLE was demonstrated to be suitable for the synthesis of organic materials in form of nanostructures. To prepare targets, 3% polyethylene powder was dissolved in toluene and frozen at liquid nitrogen

Functionalized implants represent an advanced approaching in implantology, aiming to improve the biointegration and the long-term success of surgical procedures.Wereport on the synthesis of hydroxyapatite (HA) thin films on polymethylmetacrylate (PMMA) substrates – used as cranio-spinal implant-type structures – by two alternative methods: pulsed laser deposition (PLD) and radio-frequency magnetron sputtering (MS). The deposition parameters were

Wereport the deposition byMAPLE of: (i) a novel polyethylene glycol derivative with carboxyl functional groups and (ii) a block copolymer: poly(ethylene glycol)methyl ether-block-poly(caprolactone)-blockpoly( ethylene glycol)methyl ether. We used a KrF* excimer laser source (l = 248 nm, t = 25 ns, n = 5 Hz). The laser fluence was set within the 200–700 mJ/cm2 range. The deposited thin films have been investigated by FTIR and AFM.We have concluded

We report thin film deposition of polyvinyl alcohol functionalized with carboxylic groups bound to aromatic nucleus (PVACOOH) by matrix-assisted pulsed laser evaporation (MAPLE). We used a KrF* excimer laser source (l = 248 nm, t = 25 ns, n ¼ 5 Hz). The obtained thin films have been investigated by FTIR, AFM, and in vitro tests. We identified the best compromise between the parameters of laser processing and characteristics of nanostructured thin

We report on the synthesis by pulsed laser deposition with a KrF* excimer laser source (l = 248 nm, t = 25 ns) of bioglass thin films of 6P57 and 6P61 types. Physiology, viability, and proliferation of human osteoblast cells were determined by quantitative in vitro tests performed by flow cytometry on primary osteoblasts cultured on pulsed laser deposited bioglasses. Both types of glass films proved to be appropriate mediums for cell survival and
