Argon Plasma Treatment In article 2200397, Teresa Gatti, Francesco Lamberti, and co-workers show how a cuprous oxide surface activated by Ar plasma treatment can promote the hydrogen evolution under light in typical photelectrochemical experiment: is immersed water (sketch modules bottom) that transformed hydrogen. The effect of to keep unflawed, thus avoiding rapid reduction metallic copper as...

The use of SU-8 photoresist as a structuring material for portable capillary-flow cytometry devices has been restricted by the nearhydrophobic nature of the SU-8 surface. In this work, we evaluate the use of chemical and plasma treatments to render the SU-8 surface hydrophilic and characterise the resulting surface utilising a combination of techniques including contact angle goniometry, atomic...

This work compares structural and optical properties of silicon nanocrystals prepared by two fundamentally different methods, namely, electrochemical etching of Si wafers and low-pressure plasma synthesis, completed with a mechano-photo-chemical treatment. This treatment leads to surface passivation of the nanoparticles by methyl groups. Plasma synthesis unlike electrochemical etching allows se...

Investigations of atomic-layer deposition GaP layers on Si substrates with different orientations and preliminary surface treatment have been carried out. The was out by the method plasma enhanced using in situ argon plasma. It shown that at initial stage growth precisely oriented (100) misorientation, two-dimensional occurs both after chemical treatment. Upon (111) substrates, surface, a trans...

Graphene as one type of well-known solid lubricants possesses different nanotribological properties, due to the varied surface and structural characteristics caused by different preparation methods or post-processes. Graphene nanosheets with controllable surface wettability and structural defects were achieved by plasma treatment and thermal reduction. The nanotribological properties of graphen...

Polyetheretherketone (PEEK) has good chemical and biomechanical properties that are excellent for biomedical applications. However, PEEK exhibits hydrophobic and other surface characteristics which cause limited cell adhesion. We have investigated the potential of Ar plasma treatment for the formation of a nanostructured PEEK surface in order to enhance cell adhesion. The specific aim of this s...

Dielectric barrier discharge (DBD) plasma at atmospheric pressure in air was applied to a poplar veneer surface. Effects of plasma processing rate on surface morphology, chemical property, and surface wettability of the poplar veneer were investigated. The adhesion strength of urea formaldehyde (UF) glued plywood manufactured from the modified veneer was also studied. Atomic force microscopy (A...

Abstract Nanostructured ceramics of the composition Bi 0.95 La 0.05 FeO 3 were fabricated, and structure was studied before after exposure to an argon plasma flow at a temperature ∼ 600 °C for 30 minutes. Plasma treatment surface, with positive effect formation monolithically conjugated increase in size grain crystallites, leads decrease proportion main phase on surface ∼70%. It has been establ...
