Abstract Polymer materials are widely employed in many fields due to the ease with which they can be formed into complex shapes, their versatile mechanical properties, light weight, and low cost. However, applications hindered by chemical compatibility of polymer surfaces, generally hydrophobic bond poorly other media such as paints, glues, metals biological media. While surfaces treated wet processes, aggressive reagents detrimental environment, limiting range modifications that achieved...
In this study, recent advances in tailoring the surface properties of polymers for optimization adhesion various coatings by non-equilibrium gaseous plasma are reviewed, and important findings stressed. Different authors have used experimental setups reported results that scatter significantly sometimes contradictory. The correlations between processing parameters drawn, discrepancies explained. Many explained improved with adjustment free energy or wettability polymer substrate tension...
Abstract In this paper, we present a study on the surface modification of polyethyleneterephthalate (PET) polymer by plasma treatment. The samples were treated nitrogen and oxygen for different time periods between 3 90 s. was created radio frequency (RF) generator. gas pressure fixed at 75 Pa discharge power set to 200 W. in glow region, where electrons temperature about 4 eV, positive ions density 2 × 10 15 m −3 , neutral atom 21 1 nitrogen. changes morphology observed using atomic force...
Direct plasma oxidation of iron substrates results in the nucleation and growth α-Fe2O3 nanowire nanobelt arrays (see image). The initial heating early stages determines density, nanowires nanobelts is a function temperature-dependent diffusion atoms radical flux on surface.
Metal foils convert to metal oxide nanowires at ∼50–300 °C when oxidized using weakly ionized, highly dissociated oxygen plasmas in an inductively coupled RF system (see Figure). The mechanism is believed involve spontaneous nucleation of nanocrystals (due supersaturation the subsurface layers foil with O2) followed by basal attachment limited mobility low temperatures), leading rapid nanowire growth.

Gold nanoparticles (AuNPs) have been investigated as a promising reagent for cancer therapy in various fields. In the meantime, cold atmospheric plasma has shown exquisite selectivity towards cells. this paper, we demonstrate that there is synergy between gold and therapy. Specifically, concentration of AuNPs plays an important role on At optimal concentration, can significantly induce glioblastoma (U87) cell death up to 30% overall increase compared control group with same dosage but no...
This feature article introduces a deterministic approach for the rapid, single-step, direct synthesis of metal oxide nanowires. is based on exposure thin samples to reactive oxygen plasmas and does not require any intervening processing or external substrate heating. The critical roles plasmas, surface processes, plasma-surface interactions that enable this growth are critically examined by using viewpoint. essentials experimental procedures reactor design presented related key process...
We observed two long-range-ordering structures of oxygen vacancies, one in every tenth plane (33̅0) and another fourth (11̅2) α-Fe2O3 nanowires nanobelts synthesized under the same conditions. Interestingly, both types oxygen-vacancy found different have an equivalent ordering distance 1.45 or 1.47 nm were parallel to growth direction nanobelts. Lattice mismatch induced strain at temperatures seems justify vacancy-ordering may explain reason for occurrence such various metal oxide grown from...
Surface modification of polymers has become a vibrant field research on account myriad rationales which stimulated numerous efforts.

Though it does not address all challenges involved, this communicates and highlights, concise discussion, findings efforts undertaken in recent decades. It is ultimately...
The response of an originally developed catalytic sensor with a Nb2O5 nanowire array at its outer surface to the varying density O atoms is experimentally and numerically studied. This technique can be used measure one order magnitude lower densities achieve stable linear in significantly broader pressure range compared conventional probes flat surface. nanostructured also acts as thermal barrier against overheating. approach generic for reactive species detection other gas environments.
This review describes different strategies of surface elaboration for a better control biomolecule adsorption. After brief description the fundamental interactions between surfaces and biomolecules, various routes are presented dealing with attachment functional groups mostly thanks to plasma techniques, grafting from methods, adsorption surfactants. The stimuli-responsive polymers is also pointed out. Then, discussion focused on protein phenomena showing how their solid complex. mechanism...
