Niet afgebeeld. 1896 edition. Uittreksel: ...van kai met een verbaal woord, bij de verleden deelwoorden met raa, den passieven vorm met ndai en het participium passivum praesens. behandeld in 62, de eenigste vormen, waarin zich in het Bim. eene bepaalde passieve constructie ontwikkeld heeft. Dit is zeer begrijpelijk, bij de actieve constructie toch is het alleen maar eene zaak van vorm of men zegt: ta-bonto-ku kai malanta of ta-bonto-kai-ku malanta (vgl. de vorige ), bij de passieve constructie daarentegen gaat daaraan tevens verschil in beteekenis gepaard. Beteekenen toch, bijv. de van het eenvoudige diki (binden) afgeleide vormen raa-diki en ndai diki, dat, wat gebonden is en dat, wat te binden is (dat, wat gebonden wordt), zoo hebben de van het uit diki en kai samengestelde werkwoord diki afgeleide vormen raa-diki kai en ndai diki kai eene beteekeuis, die wij moeten omschrijven mei, dat, waarmede is gebonden," en dat, waarmede te binden is (gebonden wordt)." Heeft het werkwoord oorspronkelijk intransitieve beteekeuis, dan wordt het door samenstelling met kai transitief, zoodat er dus ook bovengenoemde passieve vormen van afgeleid kunnen worden, bijv. van mat (komen) raa-mai kai en ndai mai kai, de beteekenis van welke vormen wij moeten omschrijven met dat, waarmede (men) gekomen is" en dat, waarmede men komen moet (dat, waarmede men komt)." Wat de beteekenis dezer vormen betreft, is nog op te merken, dat zij behalve het instrument, ook nog de oorzaak kunnen aanduiden, in welk geval wij ze op bovengenoemde wijze kunnen omschrijven door in plaats van waarmede," waardoor" of waarom" te bezigen.

Recent developments in the technology of silicon nanocrystals and silicon nanostructures, where quantum-size effects are important, are systematically described including examples of device applications. Due to the strong quantum confinement effect, the material properties are freed from the usual indirect- or direct-bandgap regime, and the optical, electrical, thermal, and chemical properties of these nanocrystalline and nanostructured semiconductors are drastically changed from those of bulk silicon. In addition to efficient visible luminescence, various other useful material functions are induced in nanocrystalline silicon and periodic silicon nanostructures. Some novel devices and applications, in fields such as photonics (electroluminescence diode, microcavity, and waveguide), electronics (single-electron device, spin transistor, nonvolatile memory, and ballistic electron emitter), acoustics, and biology, have been developed by the use of these quantum-induced functions in ways different from the conventional scaling principle for ULSI.

Nanocrystals have been described as any nanomaterial with at least one dimension Ü 100nm and that is singlecrystalline. More properly, any material with a dimension of less than 1 micron, i.e., 1000 manometers, should be referred to as a nanoparticle, not a nanocrystal. For example, any particle which exhibits regions of crystallinity should be termed nanoparticle or nanocluster based on dimensions. These materials are of huge technological interest since many of their electrical and thermodynamic properties show strong size dependence and can therefore be controlled through careful manufacturing processes. Crystalline nanoparticles are also of interest because they often provide single-domain crystalline systems that can be studied to provide information that can help explain the behaviour of macroscopic samples of similar materials, without the complicating presence of grain boundaries and other defects. Semiconductor nanocrystals in the sub-10nm size range are often referred to as quantum dots. This book presents the latest research in the field.
