Three imines comprised of 5-nitrothiophen-2-yl as electron-accepting and phenols electrondonating groups were synthesized used chromogenic chemosensors to detect alkylamines. The compounds are colorless in water, but their deprotonation by the alkylamines generates corresponding colored phenolates, which can be those analytes. addition cetyltrimethylammonium bromide (CTAB) causes bathochromic s...

Bentonite was modified with cetyltrimethylammonium bromide (CTAB). The organically bentonite (OMB) used to remove phenol from aqueous solution, the microstructural changes were characterized by X-ray diffraction (XRD) and scanning electronic microscopy (SEM), adsorption kinetic obtained using batch test results. results indicated that rate of onto OMB positively correlated initial concentration...

Understanding the effects of electrical double layers (EDL) and tribo-induced electric fields on electroosmotic behaviors lubricants is important for developing high-performance water-based lubricants. In this study, EDL conductivities aqueous containing a surfactant 3-[(3-cholamidopropyl)-dimethylammonio]-1-propanesulfonate (CHAPS) or cetyltrimethylammonium bromide (CTAB) were analyzed. The in...

Singlet Oxygen Sensor Green (SOSG) is the most widely used fluorescent probe for detecting singlet oxygen (1O2). 1O2 can be efficiently produced by exciting surface plasmon of gold nanoparticles with laser pulses. However, are usually embedded in a chemical stabilizer that interact SOSG, leading to erroneous detection 1O2. This article shows emission properties SOSG strongly depend on concentra...
