Thermal sensor based on a polymer nano lm

In this work, we have developed a thermal sensor based on poly(3,4 ethylenedioxythiophene) (PEDOT) nano lms as thermoelectric material. The PEDOT nano lms have been synthesized by the electrochemical polymerization method. The thicknesses of the lms were around 120 nm. The doping level of PEDOT was controlled by chemical reduction using hydrazine. The achieved Seebeck coefficient is 40 μV/K. A ...

Benefit of polyhexamethylene biguanide in Fusarium keratitis.

PURPOSE To report a series of 3 patients with soft contact lens-related Fusarium keratitis. Two of them were treated with the antiamoebic polyhexamethylene biguanide 0.02% (PHMB) in combination with antifungal drugs, and 1 patient was treated with PHMB as sole antifungal regimen. METHODS Chart review of 3 patients treated with PHMB in Fusarium keratitis. Two of them were refractory to the com...

Evaluating a dressing impregnated with polyhexamethylene biguanide

Aims: To evaluate a new polyhexamethylene biguanide (PHMB) foam dressing for inclusion in the specialist dressing section of a trust’s wound management formulary. Methods: KendallTM AMD (Covidien) antimicrobial foam dressing’s use was reviewed through a retrospective evaluation of patients who had been treated with the dressing. Data was collected from the medical and nursing notes of 25 patien...

Automatic Carbon Dioxide-Methane Gas Sensor Based on the Solubility of Gases in Water

Biogas methane content is a relevant variable in anaerobic digestion processing where knowledge of process kinetics or an early indicator of digester failure is needed. The contribution of this work is the development of a novel, simple and low cost automatic carbon dioxide-methane gas sensor based on the solubility of gases in water as the precursor of a sensor for biogas quality monitoring. T...
