Size Selected Clusters on Surfaces
Size selected metal oxide, sulfide and oxynitride clusters, soft-landed onto highly ordered pyrolytic graphite (HOPG) at room temperature, have been studied in this work. Based on their size and chemical compositions, the deposited clusters have exhibited various surface structures as illustrated by in situ Scanning Tunnelling Microscope (STM) and ex situ Atomic Force Microscope (AFM). In contr...
متن کاملOPTIMIZATION OF OPENING SIZE FOR CASTELLATED BEAM WITH SINUSOIDAL OPENINGS
Castellated beams are generally provided with hexagonal and circular openings in the web portion. However, in view of structural applications, appropriate size and shape of openings in web are always a major issue of concern. Research work carried out in optimizing sizes of castellated beam with hexagonal openings have reported that castellated beams fail mainly by local failure modes and stres...
متن کاملMelting, premelting, and structural transitions in size-selected aluminum clusters with around 55 atoms.
Heat capacities have been determined for unsupported aluminum clusters, Al49(+) - Al63(+), from 150 to 1050 K. Peaks in the heat capacities due to melting occur between 450 and 650 K (well below the bulk melting point of 933 K). The peaks for Al+51 and Al+52 are bimodal, suggesting the presence of a premelting transition where the surface of the clusters melts around 100 K before the core. For ...
متن کاملlanguage learning strategies and vocabulary size of iranian efl learners
learning a second or foreign language requires the manipulation of four main skills, namely, listening, reading, speaking, and writing which lead to effective communication. it is obvious that vocabulary is an indispensible part of any communication, so without a vocabulary, no meaningful communication can take place and meaningful communication relies heavily on vocabulary. one fundamental fac...
Spectroscopy and reactivity of size-selected Mg¿–methanol clusters
a deuterium atom to create CH3D. This geometry, which allows facile production of CH3D, is not found in the larger cluster structures. This type of concerted mechanism for the elimination of methane was proposed by Davis et al. from their work on collisions of Ba1CH3OH. 40 They point out that the barrier for such a reaction is high, as the C–O bond must be nearly broken for the reaction to proc...
