The adhesion durability of coatings and encapsulant materials utilized in electronic packaging is vital for device reliability in the microelectronics industry. Due to adverse operating conditions such as high moisture and high temperature environments, the adhesion between an adhesive and its substrate is typically compromised. This thesis addresses the advantages of employing plasma pretreatm...

OBJECTIVES The purpose of this study was to investigate the process of hydrolysis and chemical stability of a pre-activated silane solution stored for different periods of time. The tensile bond strength of resin composite to ceramic was also evaluated in order to determine the functional effectiveness after storage of the pre-activated silane solutions. METHODS Silane solutions using gamma-m...

In this communication, a bis-silane prepolymer was used to modify epoxy resin, aiming enhance the corrosion resistance of coatings on aluminum alloy substrates. The prepared by tetraethoxysilane (TEOS) and γ-glycidoxypropyl trimethoxysilane (GPTMS). behavior silane-epoxy studied. Compared with silane monomer-modified coatings, bis-silane-modified have lower coating capacitance (Cc), higher char...

Titanium dioxide (TiO2) nanoparticles, with an average size of about 45 nm, were encapsulated by polystyrene using in situ nitroxide mediated radical polymerization   in the presence of 3-aminopropyl triethoxy silane (APTES) as a coupling agent and 2, 2, 6, 6-tetramethylpiperidinyl-1-oxy  as a initiator. First, the initiator for NMRP was covalently bonded onto the surface of Titanium dioxide na...

Using the University of California Berkeley Infrared Spatial Interferometer with a radio frequency (RF) Ðlter bank, the Ðrst interferometric observations of mid-infrared molecular absorption features of ammonia and silane with very high spectral resolution (j/*jD 105) were made. Under the 3 4 assumptions of spherical symmetry and uniform outÑow, these new data permitted the molecular stratiÐcat...

Microcrystalline growth regimes and solar cells obtained in different pressure and silane depletion conditions are studied in a large area KAI-S plasma reactor. The microcrystalline material quality is systematically investigated by Fourier Transform Photocurrent Spectroscopy (FTPS) to evaluate the defect density. It is shown that higher pressure and silane depletion positively affect the mater...

We measure silane density and Sulfo-EMCS cross-linker coupling efficiency on aminosilane films by high-resolution X-ray photoelectron spectroscopy (XPS) and atomic force microscopy (AFM) measurements. We then characterize DNA immobilization and hybridization on these films by (32)P-radiometry. We find that the silane film structure controls the efficiency of the subsequent steps toward DNA hybr...

AIM The aim of this study was to evaluate the effect of surface treatments on shear bond strength (SBS) of Turkom-Cera (Turkom-Ceramic (M) Sdn. Bhd., Puchong, Malaysia) all-ceramic material cemented with resin cement Panavia-F (Kuraray Medical Inc., Okayama, Japan). MATERIALS AND METHODS Forty Turkom-Cera ceramic disks (10 mm × 3 mm) were prepared and randomly divided into four groups. The di...

We have studied the effects of silane coupling agents used for the surface treatment of fiber on the tribological properties of hemp fiber (HF) reinforced plant-derived polyamide 1010 (PA1010) biomass composites. Hemp fibers were surface-treated by two surface treatment methods: (a) alkali treatment by sodium hydroxide solution and (b) surface treatment by silane coupling agents. Three types of...

OBJECTIVES This study evaluated the influence of a multi-mode universal adhesive (MUA) containing silane (Single Bond Universal, 3M EPSE) on the bonding of resin cement to lithium disilicate. MATERIALS AND METHODS Thirty IPS e.max CAD specimens (Ivoclar Vivadent) were fabricated. The surfaces were treated as follows: Group A, adhesive that did not contain silane (ANS, Porcelain Bonding Resin,...
