Closed-cage tungsten oxide clusters in the gas phase.
During the course of a study on the clustering of W-Se and W-S mixtures in the gas phase using laser desorption ionization (LDI) mass spectrometry, we observed several anionic W-O clusters. Three distinct species, W(6)O(19)(-), W(13)O(29)(-), and W(14)O(32)(-), stand out as intense peaks in the regular mass spectral pattern of tungsten oxide clusters suggesting unusual stabilities for them. Mor...
متن کاملClosed-cage clusters in the gaseous and condensed phases derived from sonochemically synthesized MoS2 nanoflakes.
The Mo(13) clusters we previously reported were derived from MoS(2) flakes prepared from bulk MoS(2), although the nature of the precursor species was not fully understood. The existence of the clusters in the condensed phase was a question. Here we report the preparation of MoS(2) nanoflakes from elemental precursors using the sonochemical method and study the gas-phase clusters derived from t...
متن کاملAssembly and structural analysis of a covalently closed nano-scale DNA cage
The inherent properties of DNA as a stable polymer with unique affinity for partner molecules determined by the specific Watson-Crick base pairing makes it an ideal component in self-assembling structures. This has been exploited for decades in the design of a variety of artificial substrates for investigations of DNA-interacting enzymes. More recently, strategies for synthesis of more complex ...
متن کاملCage Culture: Species Suitable for Cage Culture
for cage culture. Species which have been researched and successfully reared in cages in the southeastern region of the U.S. include: catfish, trout, tilapia, striped bass, red drum, bluegill sunfish, crappie, and carp. Other species may be suitable for cage culture but research has lagged behind other aquaculture research in recent years. Interest in cage culture has been revived as an alterna...
متن کاملHuman rib cage distortability.
In five normal men, we divided the rib cage into lung-apposed [pulmonary rib cage (RCp)] and diaphragm-apposed [abdominal rib cage (RCab)] compartments and calculated their absolute cross-sectional areas (Arc,p and Arc,ab) by anteroposterior and lateral dimensions measured by magnetometry. Distortion was quantified as the displacement of RCp and RCab produced by diaphragmatic twitches away from...
