Solubility of lornoxicam in various pure solvents and solvent-cosolvent mixtures was studied to understand drug vehicle interactions and in order to get the required solubility equal to the dose of lornoxicam, i.e., 4 mg/ml for development of solution formulation. Polyethylene glycol (PEG) 400, propylene glycol, ethanol, water, dimethyl formamide, dimethyl sulfoxide, and ethyl acetate were used...

Today concrete is most generally utilized development material in the world due to its strength and sturdiness properties. To attain good strength, curing of concrete is important so we introduce the concept of self-curing concrete rather than immersion or sprinkle curing to avoid water scarcity. It was observed that water solvent polymers can be utilized as a self-curing agent, i.e. polyethyle...

We have synthesised novel oligo(ethylene glycol), CF3-terminated switching self-assembled monolayers, which allow the force experienced by a hydrophobic object to be controlled via the ionic strength of the environment.

A device for automatically maintaining any desired concentration of triethylene or propylene glycol vapor in air is described. It can also be used to measure very rapidly the glycol content of room air. This instrument should greatly facilitate tests of the efficacy of glycol vapors in preventing air-borne infections.

ABSTRACT An efficient method for the synthesis of N,N-bis(phenacyl)anilines was developed via smooth condensation of anilines with α-bromoacetophenones in the presence of sodium carbonate as acid acceptor and polyethylene glycol 400 (PEG 400) as catalyst at room temperature under solvent-free conditions by using 350 W ultrasound irradiation. In addition to experimental simplicity, the main adva...

In this study the temperature dependent confor-mation of hexa(ethylene glycol) self-assembling monolayers (SAMs) under aqueous conditions (in situ) is investigated. To this end characteristic absorption modes in the fingerprint region (1050-1500 cm(-1)) were monitored with real-time polarization modulation infrared spectroscopy. We found a temperature induced conformational change from predomin...

Transdermal delivery of therapeutic biomolecules (including peptides) can avoid enzymatic digestion that occurs in the oral route. (Polyethylene glycol) diacrylate (PEGDA)-based microneedles, with good biocompatibility, are easily fabricated through photo-polymerization with a precisely controlled structure. It has successfully been used for the transdermal delivery of small molecule drugs such...
