To accommodate efficient heating of coarse solids, it would be desirable to break the fall of these particles during their descent by means of baffles in order to prolong their residence time, as shown schematically in Fig. 13 (Kwauk, 1979b). In this respect, a good baffle needs to cover up to 100% of the cross-sectional area traversed by vertical flow, and yet permit oblique passage as near to 100% as possible. Also, baffles should distribute solids laterally in order to give uniform solids population in the heat transfer apparatus. Thus, conceptually, an ideal baffle plate should consist of a cellular array, structurally robust, of deflectors made of infinitesimally thin sheet materials. [Pg.515]

Currently, protein microarrays can be divided into various types depending on the strategies to be chosen. For example, according to the array structure and shape, protein microarrays include 3D-surface structure [30, 31], nanowell [32], and plain chips [33-36], Meanwhile, considering the field of application, protein microarrays can be classified into five categories antibody array, antigen or reserve array, functional array, capture array, and solute array. Table 11.6 shows the differences among them. [Pg.359]

Methods have been developed for fabrication of the highly-ordered titania nanotuhe arrays from titanium thin films atop a substrate compatible with photolithographic processing, notably silicon or FTO coated glass [104]. The resulting transparent nanotuhe array structure, illustrated in Fig. 5.16, is promising for applications such as anti-reflection coatings and dye sensitized solar cells (DSSCs). Fig. 5.17 shows the typical anodization behavior of a 400 nm Ti thin film anodized at 10 V in an HE based electrolyte. Eor a fixed HE concentration, the dimensions of the tube vary with respect to... [Pg.287]

Under UV (320-400 nm, 100 mW/cm ) illumination a maximum photoconversion efficiency of 7.9% was obtained for short nanotube arrays anodized in boric acid contained electrolyte [103], with a hydrogen generation rate of 42 mL/h W. Under full spectrum illumination (AM 1.5, 100 mW/cm ), a photoconversion efficiency of 0.45% was obtained. The enhanced photoresponse of the boric acid anodized sample is not due solely to a modified nanotube array structure since the maximum nanotube array length achieved is about 600 nm. It is possible boron, which is difficult to identify by XPS, remains inside the titania matrix and affects its charge transfer properties. [Pg.326]

We note the unique, highly ordered titania nanotube array structure enables the conductive electrolyte, in this work IM KOH, to permeate the entire internal and external surfaces, hence there is a constant electrostatic potential along the length of the tubes (no RC ladder effect). Therefore long-range electron transport is dominated... [Pg.328]

(a) The cell mount design of the integrated PV array of Figure 1, which uses laminated conductive and insulating layers on top of an aluminium substrate in a printed circuit board-type panel (7). The array produces 20 kW at 20°C ambient and 850 W/m2 direct sunlight, and measures 155 m2. The lens is a molded acrylic Fresnel lens parquet mounted on the front of the array structure. The PV panel is mounted on the back of the array structure and is... [Pg.105]

As stated before, PGVL is too large to be fully enumerated practically. Therefore our strategy is to find a way to focus in a just-in-time manner on much smaller sub-regions ( 104) of PGVL for subsequent on-the-fly enumeration followed by standard similarity search against the same query molecule. It is intuitively evident that a virtual compound space built from parallel synthesis reaction protocols has inherent array structures in the form of implicit arrays of related just-in-time enumerated compounds, even if those compounds do not have their molecular structures yet enumerated at the time this inherent array structure is exploited. [Pg.256]

A solar photovoltaic system contains, in addition to solar cells and module(s), an array structure to support the modules, power-conditioning circuitry for control and modification of the output, and a means of storing energy if required. All elements beyond the module are referred to as balance-of-system (BOS) components. The cost of BOS items is nominally about equal to the cost of the PV module. However, the BOS fractional cost contribution can vary from one- to two-thirds of the total installed cost of a system, depending on application. [Pg.1300]

The determination of a one-dimensional ladder molecular array structure of O2 molecules was first performed using in situ synchrotron powder XRD measurements on CPL-1 accommodating O2 molecules.77 78 The intermolecular distance of the adsorbed O2 molecules (3.28(4) A) is close to the nearest distance in the solid a-02 phase, whose close-packed structure appears below 24 K. This result indicates that O2 molecules adsorbed in the nanochannels form van der Waals dimers, (02)2- The X-ray structural analysis shows that 02 molecules are in the solid state rather than the liquid state, even at 130 K and 80kPa, which are much higher than the boiling point of bulk O2 at atmospheric pressure, 54.4 K. This result is ascribed to the strong confinement effect of CPL-1. [Pg.245]

Erosion Dielectric erosion depends on pattern density and has to be kept below 50nm in microelectronic array structures [14]. Erosion can also occur in microfabrication when pattern arrays have to be planarized. Due to larger vertical and lateral dimensions, the requirements are relaxed compared to microelectronics. [Pg.409]

In addition to nanoaperture arrays, structured af>ertures could provide higher fluorescence rate enhancement than single apertures, while still enabling efficient signal-to-background discrimination. Examples include the bull s eye structures (56, 23), nanopockets (68) or combined slit and aperture (69). [Pg.515]

Stoddart and co-workers transferred the strategy of template-directed synthesis to the formation of the first molecular system consisting of five interlocked rings in a linear array (Structure 51). They suggested that this [5]catenane should be called olympiadane [64]. Recently they reported the self-assembly of a new type of rotaxane, in which three side chains are linked directly to a single central core, producing a dendritic-type structure [65]. [Pg.934]
