The increasingly common application of the near-infrared (NIR) hyperspectral imaging technique to the analysis of food powders has led to the need for optical characterization of samples. This study was aimed at exploring the feasibility of quantifying penetration depth of NIR hyperspectral imaging light for milk powder. Hyperspectral NIR reflectance images were collected for eight different mi...

Molecular self-assembly films are expected to tailor the surface process by the periodic nanostructures and add-on functional groups. In this work, a molecular network of melamine with featured pores of subnanometer size is prepared on the Au(111) surface, and is found to be able to trap the gold adatoms and concomitant single vacancies generated under the impingement of CO molecules at room te...

Pt3Fe(111), Pt3Fe(775) = 7(111)–(111), and Pt3Fe(544) 9(111)–(100) electrodes show the highest activity in low-index planes, n(111)–(111), n(111)–(100) series of Pt3Fe, respectively. The surfaces these were modified with hydrophobic species such as THA+, melamine, ionic liquid ([MTBD][beti]), effects on oxygen reduction reaction (ORR) studied. All improved ORR all examined. Pt3Fe(111) 0.1 M HCl...

Three 2D Ag(I)-framework isomers were constructed from enantiopure camphor-10-sulfonic acids or racemic camphor-10-sulfonic acids, together with achiral 4-aminobenzoic acids. In complex 1, (+)-camphor-10-sulfonic acids bridge the single left-handed helices that are made up of Ag ions and 4-aminobenzoic acids, generating a homochiral 2D layer. In such a structure, the interweaving of triple left...

Melamine is a nitrogen-rich industrial chemical which is occasionally used to increase the apparent protein content of different products destined for human and animal consumption. In this work, a liquid chromatographic procedure that uses micellar mobile phases of sodium dodecyl sulfate (SDS) buffered at pH 3, a C18 column and UV detection is reported for the determination of melamine in diete...

This article describes reactions of the trivalent melamine derivatives C6H3-1,3,5-[CONHC6H4-3-N(CH2C6H44-C(CHi)3)COC6H3-2-(NHCrN3(NH2XNHCH2CH2C(CH3)3))-5-Brl, (hubM3) and (CH3),COC(O)NHCICH2O(CHz)rSCH2C(O)NHC6H4-2-NHC3N3(NH2)(NH(CH2)2C(CH3)r)1, (trisMr) with the bivalent isocyanurate derivatives CuHzl ,5.[CH(CH)2|z-2,4.[cH,ff i(o)]z(benzCA,)andc4o-2'5-[cH(cH3)2]?-3'4-[cH,ff i6[ NHC(O)12 (furanC...

Nitrogen-doped carbon nanotubes (CNx–NTs) were prepared using a floating catalyst chemical vapor deposition method. Melamine precursor was employed to effectively control nitrogen content within the CNx–NTs and modulate their structure. X-ray photoelectron spectroscopy (XPS) analysis of the nitrogen bonding demonstrates the nitrogen-incorporation profile according to the precursor amount, which...
