We combine classical empirical potentials and density functional theory (DFT) calculations to characterize the catalyst/electrode interface of a promising device for artificial photosynthesis. This system consists of inorganic Ru-polyoxometalate (Ru-POM) molecules that are supported by a graphitic substrate functionalized with organic dendrimers. The experimental atomic-scale characterization o...

Recently, there has been much concern over the dumbing down of production and operations management (POM) courses in response to the repudiation of the theory-heavy operations research (OR) approach that became dominant during the 1970s. However, although almost everyone agrees that a new POM framework is needed, there is as yet little agreement on what it should be like. As a result, there is ...

Sixty percent of the world ocean by area is contained in oligotrophic gyres [Longhurst A (1995) Prog Oceanog 36:77-16], the biomass of which is dominated by picophytoplankton, including cyanobacteria and picoeukaryotic algae, as well as picoheterotrophs. Despite their recognized importance in carbon cycling in the surface ocean, the role of small cells and their detrital remains in the transfer...

A series of polyoxymethylene (POM)/hydroxyapatite (HAp) nanocomposites for long-term bone implants were prepared by melt processing using POM with different molecular weight. Bioactivity was examined by incubating the samples in simulated body fluid. Moreover, in vitro stability, wettability, thermal stability, and formaldehyde release process were investigated. Results of in vitro investigatio...

OBJECTIVE To determine whether the distribution of peripheral blood mononuclear cells (PBMCs) is altered in paraneoplastic opsoclonus-myoclonus (POM). METHODS PBMCs from 17 children with POM, 17 children with OM but no tumor, and 17 controls were immunophenotyped using a comprehensive panel of surface markers by dual-laser flow cytometry. All groups were matched for age and gender; POM and OM...

Odontogenic myxomas are rare odontogenic tumors of jaw characterised by accumulation of mucoid ground substance with little collagen. Peripheral odontogenic myxoma (POM) is extra-osseous variant of odontogenic myxomas, occurring solely in the soft tissue covering the tooth bearing portion of jaws. POM is exceedingly rare, less than 10 cases have been published till date. A case of POM is report...

mixed-addenda vanadium substituted polyoxometalate supported on anatase tio2 crushed nano leaf was synthesized by an unusual reaction with titanium tetraisopropoxide at 100 ºc via sol–gel method under oil-bath condition. the materials characterized by xrd, tem,  ir and uv–vis  techniques.  in  the  present  work,  efficient  oxidative  of  thiols  with  polyoxometalate-tio2/hydrogen  peroxide  ...

Using electrostatic layer-by-layer self-assembly (ELSA), the formation of multilayers with polyelectrolytes and nanoscopic polyoxometalate (POM) clusters of different sizes and charges is investigated. The multilayers are characterized by UV-vis absorption spectroscopy, optical ellipsometry, cyclic voltammetry, and atomic force microscopy. In all cases, it is possible to find experimental condi...
