Glycol dehydration is the most common and economical water removal method from natural gas streams. However, of low-pressure requires use higher concentration TEG (Triethylene Glycol) or TREG (Tetraethylene Glycol). This article describes how ejector can be used to create a vacuum in glycol reboiler achieve L-TEG/L-TREG (Lean Triethylene Glycol/Lean Tetraethylene Process simulations regeneratio...

Fluorinated tetraethylene glycol-stabilized Au nanoparticles (FTEG-AuNPs) were well-dispersed in general polar organic solvents, such as methanol (MeOH) and THF. The cast film of FTEG-AuNPs on a TEM grid and a glass substrate was found to form a highly ordered 3D-superlattice assembly, whereas tetraethylene glycol-stabilized AuNPs (TEG-AuNPs) provide an amorphous AuNP aggregation. These data in...

A new tetrathiafulvalene-anthracene dyad 1 with two "tetraethylene glycol" units was synthesized and characterized. Strong chemiluminescence was observed upon reaction of dyad 1 with singlet oxygen (1O2), and this reaction shows fairly good selectivity toward 1O2 over other reactive oxygen species. Due to the introduction of two hydrophilic "tetraethylene glycol" units, the detection of 1O2 wit...

Non-specific adsorption of immunoactive compounds on biosensor surfaces is an important concern in biosensor development. In this study, minimization of nonspecific adsorption onto selfassembled monolayer (SAM) biosensor platforms was studied using electrochemical immunoassay techniques. To compare non-specific adsorption resistance, Au electrodes individually modified with decanethiol (DT), te...

The first fluorescent cyclophane with mechano- and thermoresponsive solid-state fluorescence characteristics is reported. The new cyclophane comprises two 9,10-bis(phenylethynyl)anthracene moieties that are bridged by tetraethylene glycol spacers. The stimuli-responsiveness is based on molecular assembly changes.

The aim of the study was to evaluate whether the addition of activated carbon in the photocatalytic oxidation of biologically pretreated greywater and of a polar aliphatic compound gives synergy, as previously demonstrated with phenol. Photocatalytic oxidation kinetics were recorded with fivefold concentrated biologically pretreated greywater and with aqueous tetraethylene glycol dimethyl ether...

The aggregation of shape-persistent macrocycles with an empty cavity, an undecyldiether strand and a tetraethylene glycol strand leads in all cases to a macroscopic gelation of the solvent. However, the gelation temperatures are fine-tuned by the intraannular substituents.
