Using thermally evaporated cesium carbonate (Cs2CO3) in an organic matrix, we present a novel strategy for efficient n-doping of monolayer graphene and a ∼90% reduction in its sheet resistance to ∼250 Ohm sq(-1). Photoemission spectroscopy confirms the presence of a large interface dipole of ∼0.9 eV between graphene and the Cs2CO3/organic matrix. This leads to a strong charge transfer based dop...

This review discusses two classes of organic template-derived amorphous silicas distinguished by the nature of template-matrix interactions and the extent to which subsequent processing dictates the final pore morphology. First we discuss surfactant-templated silicas where the template-matrix interaction is via non-covalent bonding mechanisms and the pore structure is established in the solutio...

Surface-assisted laser desorption/ionization mass spectrometry (SALDI-MS) represents a powerful tool for the analysis of biomolecules, synthetic polymers, and even small organic compounds; its performances largely depend on the type of matrix materials utilized. Here, for the first time the employment of nanoporous carbons derived from metal-organic frameworks (MOFs) as novel matrices for SALDI...

Bone’s fracture resistance relies on its material properties, which can change with aging and disease. The material properties may be altered by changes in bone’s organic matrix via biochemical modifications of collagen, such as non-enzymatic glycation (NEG), which produces crosslinks known as advanced glycation end-products (AGEs). Alterations may also arise from the non-collagenous protein co...

A high-performance organic active matrix pixel was fabricated by using a metal oxide sV2O5d coupling layer that effectively integrates an organic light-emitting diode sOLEDd on top of an organic field-effect transistor sOFETd. The field-effect mobility of the OFET approached 0.5 cm2 V−1 s−1 and the ON/OFF current ratio was .103. The brightness of the OLED was on the order of 2000 cd/m2, with an...

   To fabricate a defect free and high performance mixed matrix membrane (MMM), one approach is the functionalization of inorganic nanofillers (as dispersed phase) in the organic polymer matrix (as continuous phase) to modify the interactions between two phases.  For this purpose,, raw multi-walled carbon nanotubes (rMWCNTs) were purified by acid mixture (HNO3/H2SO<sub...

Non-collagenous phosphoproteins, almost all of which can be extracted in EDTA at neutral pH in the presence of proteinase inhibitors, are identified in the matrix of chicken bone, and are therefore not covalently bound to collagen. Similarly, all the peptides containing y-carboxyglutamic acid are present in the EDTA extract and none in the insoluble residue, confirming that none is covalently l...
