Supramolecular complexation is a powerful strategy for engineering materials in bulk and at interfaces. Metal–phenolic networks (MPNs), which are assembled through supramolecular complexes, have emerged as suitable candidates surface particle owing to their diverse properties. Herein, we examine the dynamics of MPNs during thermal transformation processes. Changes local network including enlarg...

Oregano is one of the most used culinary herb and it often adulterated with cheaper plants. In this study, GC?MS was for identification quantification metabolites from 104 samples oregano (Origanum vulgare O. onites) olive (Olea europaea), venetian sumac (Cotinus coggygria) myrtle (Myrtus communis) leaves, at five different concentration levels. The metabolomics profiles obtained after two-step...

This work describes a device for electrochemical enzyme-linked immunosorbent assay (ELISA) designed for low-resource settings and diagnostics at the point of care. The device is fabricated entirely in hydrophobic paper, produced by silanization of paper with decyl trichlorosilane, and comprises two zones separated by a central crease: an embossed microwell, on the surface of which the antigen o...

An easy-to-handle eosin Y-based heterogeneous photocatalyst was prepared by post-functionalization of a polydopamine-coated open cell polyurethane foam (PDA@PUF) via the silanization adhesive layer with 3-(triethoxysilyl)propan-1-amine (APTES) and subsequent EDC-mediated coupling resulting amino-functionalized Y. The obtained macroscopic material, EY-APTES@PDA@PUF, showed good efficiency excell...

Experimental Section: Fabrication of glass devices The procedure for fabrication of SlipChip from glass was based on previous work. 1 The sodalime glass slide with chromium and photoresist coating was aligned with a photomask containing the design for the wells and the ducts, and AZ 1500 positive photoresist was exposed using standard exposure protocols. The glass plate was immersed in 0.1 mol/...

THE EFFECTS OF DIFFERENT SURFACE TREATMENTS ON THE SHEAR BOND STRENGTH OF COMPOSITE RESIN TO MACHINED TITANIUM Mohammad AlJadi, D.D.S. Marquette University, 2011 Purpose: The purpose of this study was to evaluate the shear bond strength between machined titanium and composite resin using different surface treatments. Materials and Methods: Titanium (Ti-6Al-4V) specimens were ground with 600 gri...
