We present a new method for data acquisition in time-resolved terahertz spectroscopy experiments. Our approach is based on simultaneous collection of reference and differential THz scans. Both the optical THz generation beam and the pump beam are modulated at two

The purpose of this paper is to develop a sensitive and low-cost colorimetric method for detection of melamine using simple circuitry. The stable p-nitroaniline-modified silver nanoparticles (Ag NPs) were synthesized by a zero-length covalent coupling chemistry, which showed sensitivity and

Environmentally toxic aromatic amines including nitroanilines are commonly generated in dye contaminated wastewater in which azo dyes undergo degradation under anaerobic conditions. The aim of this study was to develop a process for biological treatment of 4-nitroaniline. Three bacteria identified

Heterodyne-detected electronic sum frequency generation (HD-ESFG) spectroscopy is newly developed to obtain complex electronic chi(2) spectra of interfaces for a simultaneous detection bandwidth broader than 100 nm. HD-ESFG provides linear chi(2) spectra that have unambiguous information on the "up" versus

The determination of nitroaromatic compounds in aqueous solution was investigated at β-cyclodextrin (β-CD)/silver nanoparticle (AgNPs) composite modified ITO electrodes. This method relies on the different reduction potentials for the various nitroaromatic isomers, the different binding strengths of the nitroaromatic isomer
