The Type II isotherm is concave to the plp° axis, then almost linear and finally convex to the p/p° axis. It indicates the formation of an adsorbed layer whose thickness increases progressively with increasing relative pressure until p/p°— 1. When the equilibrium pressure equals the saturation vapour pressure, the adsorbed layer becomes a bulk liquid or solid. If the knee of the isotherm is sharp, the uptake at Point B - the beginning of the middle quasilinear section — is usually considered to represent the completion of the monomolecular layer (monolayer) and the beginning of the formation of the muldmolecular layer (multilayer). The ordinate of Point B gives an estimation of the amount of adsorbate required to cover the unit mass of solid... [Pg.19]

Furthermore, the theory is not able to account for the Type VI isotherm, which is the simplest type of layer-by-layer multilayer isotherm. The steps of a Type VI isotherm tend to lose their sharpness as the temperature is raised. However, die results of Prenzlow and Halsey (1957) showed that the mid-point (inflection) of the tread is rather insensitive to change of temperature. This is an indication that in this case it is the step height, and not Point B, which corresponds to the monolayer completion. [Pg.170]

In recent times, much attention has been paid to preparation of hlms of hybrid materials. Here, the composition (homogeneous, heterogeneous), structure (mono-layer, multilayer), thickness, and texture (roughness) can notably influence the resulting optical and electrical properties of the system. Layer-by-layer (LbL) preparation involves the sequential deposition of oppositely charged building blocks modulated by their interaction with counterions. [Pg.5]

Electrochemistry is a central theme in the interconnection of chips and other microelectronic components. The manufacture of printed wiring boards, such as single-layer, multilayer, or flexible boards, involves electroplating of the conductor that forms the electrical paths. The corrosion of these paths and the interfacial stability of the conductor-polymer composites that determine the reliability of these interconnections are electrochemical problems. [Pg.98]

To improve the operational stability, low work function metals such as Mg and Li are alloyed with more stable metals with higher work function, such as A1 or Ag, and used as cathode material. Most simply, the polymeric layer consists of a single layer. Multilayer structures of different polymers are more common. Multilayer organic devices, such as are conventionally constructed in a sequential manner ... [Pg.108]

Biosensors based on biorecognition events occurring in monolayer or thin-fihn assemblies on electronic transducers represent an important recent advance in bioelectronics [15]. The nano-architecture of the sensing interface in a mono-layer, multilayer, or thin-fihn structures precludes diffusion barriers, and hence the rapid response-times of the sensing devices are achieved. Enzyme-electrodes [16,17], immunosensors [18,19], or DNA sensors [13] were developed by tailoring nanoscale sensing interfaces on the transducer. We will specifically address the development of DNA sensors in monolayer and thin-film confignrations. [Pg.44]

In addition to reflective or colored coatings, oxide coatings on glass and silicon substrates (single layers, multilayers, and porous layers) have been used extensively as antireflective (AR) surfaces in solar-related applications to improve device efficiency and as laser-damage-resistant AR coatings for laser optics, especially in inertial confinement fusion applications [25-37]. [Pg.429]
