We present the results of our search for faint Local Group dwarf galaxies in compact high-velocity clouds (HVCs). We used digitized Palomar Observatory Sky Survey (POSS) data to examine 1 square degree of sky around each of ∼ 250 northern hemisphere HVCs. The POSS images were processed to remove foreground stars and large-scale backgrounds, smoothed to enhance arcminute-sized low surface bright...

Mechanically separated chicken (MSC) from 2 different separation methods (MSC1, Beehive separator, aged bones [Provisur Technologies, Mokena, IL]; MSC2, Poss fresh [Poss Design Limited, Oakville, Ontario, Canada]) and breast trim (CBT) were used as raw materials in frankfurters. Texture, color, lipid oxidation measured over a refrigerated storage period of 98 d. Both MSC higher fat lower moistu...

A facile synthetic pathway leading to significant yields of bifunctional polyhedral oligomeric silsesquioxanes (POSS) with two different functionalities on the same cage structure, namely Ti-NH2POSS, is proposed in this manuscript.

The clinical longevity of tooth-coloured restorations, whether direct or indirect, using composites and ceramics, greatly depends on the quality and stability of their marginal adaptation. In this issue, two interesting studies 7,15 bring this subject and lead us to an exciting discussion. Poor marginal adaptation of direct and indirect restorations exposes the dentin pulp complex to the oral e...

A POSS functionalized with eight rigid and directional terpyridine arms was synthesized. After complexation europium, a white light emission ascribed to the presence of combined contributions from blue, green red regions detected.

This work shows the synthesis of a catalyst based on functionalization octaphenyl polyhedral oligomeric silsesquioxanes with sulfonic groups (H-Sulfo-POSS) and its performance in acetalization glycerol to yield biobased fuel additive.

Properties of cycloolefin copolymer (COC)– polyhedral oligomeric silsesquioxanes (POSS) nanocomposites, prepared by melt compounding, have been investigated. Composites retained the optical transparency of the matrix up to a nanofiller content of 5 wt %. whereas for higher percentages the formation of a crystalline phase, due to the presence of agglomerated nanoparticles, was revealed by X-Ray ...

It is demonstrated in this paper that silica nanoparticles coated with core/shell gold provide efficient thermal, optical, and morphological properties with respect to the cellulose-polyhedral oligomeric silsesquioxanes (POSS) hybrid system. The one-step synthesis of a silica/gold nanocomposite is achieved with a simultaneous hydrolysis and reduction of gold chloride in the presence of formic a...

We have examined the gypsum (CaSO4·2H2O) scaling phenomena on membranes with different physicochemical properties in forward osmosis (FO) processes. Three hollow fiber membranes made of (1) cellulose acetate (CA), (2) polybenzimidazole (PBI)/polyethersulfone (PES) and (3) PBI-polyhedral oligomeric silsesquioxane (POSS)/polyacrylonitrile (PAN) were studied. For the first time in FO processes, we...

We report molecular dynamics simulations for telechelic molecules composed of two polyhedral oligomeric silsesquioxane (POSS) cages connected by one hydrocarbon backbone dissolved in liquid normal hexane. Silsesquioxanes are novel hybrid organic-inorganic molecules that are useful as building blocks for the synthesis of nanostructured materials. By including POSS molecules within a polymeric ma...
