Mangroves are a special form of vegetation as they exist at the boundary terrestrial and marine environment. They have role in supporting fisheries stabilizing tropical coastal zones. Biochemical trophodynamic processes mangroves strongly linked to water movement, due tides waves. In this paper we present theoretical attempt predict attenuation wind-induced random surface waves mangrove forest. The energy dissipation frequency domain is determined by treating forest media with certain...

Since the theoretical foundations of radial distribution analysis liquid diffraction patterns were laid in 1927 by Zernike and Prins, progress apparatus experimental techniques has ensured a greater reliability hence confidence method as means evaluating structure liquids.

Abstract X-ray diffraction patterns have been obtained from liquid tin under good experimental conditions with particular emphasis on obtaining clean, oxide-free surfaces. The show that a considerable degree of structure exists in the melt contrast simple liquids such as molten Na, K, Cu and Au. Analysis by radial distribution method shows there are two distances atomic separation melt. first is clearly defined 3·27 Å. second about 2·7 Å, so near distance closest approach grey re-established...

GPM objective to observe global precipitation more frequently accurately. contributes climate water cycle change studies, flood prediction numerical weather forecast. consists constellation satellites carrying microwave radiometers (MWRs) and/or sounders (MWSs). frequent...

A cubic silicon cluster having eight bonds each terminated by a tert-butyl substituent, tert-butyloctasilacubane (TBOSC), is studied. TBOSC was formed and isolated chemical procedures. The optical properties of were measured in comparison with those bulk silicon. purple its absorption edge (λg) observed at 650 nm (1.9 eV) room temperature. This λg 0.8 eV larger than that It also shows photoluminescence extending to 850 77 K although no photoluminescence.

A nanometer-scale optical switch and transistor were fabricated with thioacetyl-end-functionalized poly(para-phenylene ethynylene)s Au nanogap electrodes by self-assembly. With photoirradiation, the can be switched on/off quickly a switching ratio as high 1000. Moreover, device works well p-type transistor. an increase in gate bias, strong conductance oscillation was observed this self-assembled (under low temperature 147 K), which is very likely due to single-electron charging oscillations...

A molecular junction of a poly(p-phenyleneethynylene)s derivative with thioacetate end groups (TA-PPE) was fabricated by self-assembling. Nanogap electrodes made electroplating technique used to couple thiol TA-PPE molecules. Room temperature current-voltage characteristics the exhibited highly periodic, repeatable, and identical stepwise features. First-principles calculations suggest that one possibility for equidistant step is due opening different conducting channels corresponds...

Abstract The liquid crystalline compounds having an optically active 1-methyl-alkoxy-phenyl group were synthesized. They show some abnormality, i.e., firstly rather high value of spontaneous polarization for the structural feature lacking a strongly polar group, in vicinity chiral center, and secondly sense twist S*c phase that is opposite to what was originally expected. We report characteristics these compounds.

Surface-modified gold nanorods (Au NRs) with 1,2-dipalmitoyl- sn-glycero-3-phosphothioethanol (DPPTE) were synthesized, and their self-assembled structures on a silicon substrate observed using scanning electron microscope (SEM). The Au NR-DPPTE complex formed characteristic one- two-dimensional self-assemblies induced by intermolecular interactions of surface-anchored lipids via simple drying process. interparticle distance between neighboring NRs was uniform at around 5.0 nm, which...

Gold nanorods (NRs) mixed with crown ether derivatives exhibited the efficient and selective recognition of Na+ K+ ions, which were detected by localized surface plasmon absorption in response to dispersed aggregated gold NRs. Furthermore, aggregates preferential end-to-end or side-to-side assembly NRs was observed dependent on additive concentration.
