TL;DR: In this paper, primary amine groups are anchored onto ordered mesoporous carbon in a one-step reaction, resulting in hexagonally ordered carbon materials with functional groups residing at the pore surface.
Abstract: This paper describes a single step procedure by which primary amine groups are anchored onto ordered mesoporous carbon in a one step reaction. Ordered carbon materials with functional groups residing at the pore surface are prepared using SBA-15 silica as template in combination with hydrothermal carbonisation at mild temperatures (180 °C). These functional groups are afterwards reacted with 3-chloropropylamine leading to amino-modified hexagonally ordered carbons. Transmission electron microscopy (TEM) and small angle X-ray scattering (SAXS) experiments proved that the resulting carbon materials exhibit hexagonal frameworks. Nitrogen adsorption revealed that the materials are micropore free, possessing narrow mesopores size distributions and high surface areas. The surface functionality and hydrophilicity of the carbonaceous materials were assessed by Fourier transform IR spectroscopy (FTIR), X-ray photoelectron analysis (XPS) and water porosimetry. The presence of accessible amino groups in considerable amounts was proved by elemental microanalysis, FTIR spectroscopy and thermogravimetrical analysis.

TL;DR: Several demonstrations of two-dimensional Fourier-transform spectroscopy are presented, including an example of a phase-cycling scheme that reduces noise and a spectrum that accesses two-quantum coherences, where all excitation pulses require phase locking for detection of the signal.
Abstract: The JILA multidimensional optical nonlinear spectrometer (JILA-MONSTR) is a robust, ultrastable platform consisting of nested and folded Michelson interferometers that can be actively phase stabilized. This platform generates a square of identical laser pulses that can be adjusted to have arbitrary time delay between them while maintaining phase stability. The JILA-MONSTR provides output pulses for nonlinear excitation of materials and phase-stabilized reference pulses for heterodyne detection of the induced signal. This arrangement is ideal for performing coherent optical experiments, such as multidimensional Fourier-transform spectroscopy, which records the phase of the nonlinear signal as a function of the time delay between several of the excitation pulses. The resulting multidimensional spectrum is obtained from a Fourier transform. This spectrum can resolve, separate, and isolate coherent contributions to the light-matter interactions associated with electronic excitation at optical frequencies. To show the versatility of the JILA-MONSTR, several demonstrations of two-dimensional Fourier-transform spectroscopy are presented, including an example of a phase-cycling scheme that reduces noise. Also shown is a spectrum that accesses two-quantum coherences, where all excitation pulses require phase locking for detection of the signal.

TL;DR: The results indicated that the hydrophobic interaction caused strong retention of analytes, whereas the repulsive electrostatic interaction between the negatively charged 11-MUA SAMs surface and the negative charged probe molecule would lead to the decrease of adsorption affinity.
Abstract: This paper reports the synthesis of alkanethiolate-functionalized core/shell Fe3O4/Au nanoparticles (Fe3O4@Au NPs) that combine the advantages of core/shell magnetic nanoparticles with self-assembled monolayers (SAMs). The alkanethiolates, having carboxylic acid (COOH) and methyl (CH3) terminal groups, can be easily self-assembled on the Fe3O4@Au NPs substrates. The surface composition and structure of 11-mercaptoundecanoic acid (11-MUA) and 1-dodecanethiol (11-DDT) SAMs were characterized in detail using energy-dispersive spectroscopy (EDS), Fourier transform infrared spectroscopy (FT-IR), and X-ray photoelectron spectroscopy (XPS). To further study the surface properties of the SAMs, hydrophobic, ionic, and nonionic organic compounds were selected as probe molecules. The results indicated that the hydrophobic interaction caused strong retention of analytes, whereas the repulsive electrostatic interaction between the negatively charged 11-MUA SAMs surface and the negatively charged probe molecule would l...
