A Keggin-type POM is attached to gold or glassy carbon surfaces by electro(chemical) or peptidic coupling. In addition to demonstrating the robust attachment of the POMs (by electrochemistry, XPS, and IRRAS), the surface concentration, layer thickness, and rate constant for electron transfer from the surface to the POMs have been measured. The use of such complementary techniques is mandatory t...

Polyoxometalates have been traditionally the subject of study of molecular inorganic chemistry. Yet, these polynuclear molecules, reminiscent of oxide clusters, present a wide range of structures and with them ideal frameworks for the deployment of a plethora of useful magnetic, electroionic, catalytic, bioactive and photochemical properties. With this in mind, a new trend towards the applicati...

The anti-DNA polymerase activity of a structural family of polyoxometalates has been determined. Two representative compounds of this family, possessing a saddle-like structure [(O3POPO3)4W12O36]16- (polyoxometalate I) and [(O3PCH2PO3)4W12O36]16- (polyoxometalate II) were found to inhibit all the DNA polymerases tested, with IC50 values ranging from 2 to 10 microM. A comparative study with HIV-...

This paper develops a local search approach based on diminishing neighbourhoods for optimizing the planning of a canning line at a drinks manufacturer. The search starts with a very wide range of neighbours to try to avoid early entrapment at a poor local optimum. The neighbourhood narrows as the search progresses in an attempt to home in on a good local optimum with nearly the same value as th...

Kinetic and DFT studies revealed that protonation of Ti-containing polyoxometalates (Ti-POM) lowers significantly the energy barrier for the heterolytic oxygen transfer from the Ti hydroperoxo intermediate to the alkene, increasing the activity and selectivity of alkene oxidation.

Femptolitre droplets deposited on surfaces assisted by an AFM tip are used as reactor vessels to fabricate arrays of nanoarchitectures ranging from single-crystals of metal-organic frameworks to hollow capsules of magnetic polyoxometalates.

Objective: To assess the self-efficacy level and health-related quality of life in pediatric-onset multiple sclerosis (POMS) patients. Material Methods: A cross-sectional study was conducted between January-April 2022 at Hacettepe University Department Pediatric Neurology using The Rating Chronic Illness Self-Efficacy (PRCISE) Scale Quality Life Inventory (PedsQL). Results: Twenty-nine POMS pat...

Product Oriented Manufacturing Systems (POMS) are systems designed for variable product demand markets, and dynamically reconfigured for the manufacture of a single type of product or a family of similar products at a time. POMS systems can take several forms and result from exploring the use of flexible resources, a variety of new design philosophies, technologies and approaches to manufacture...
