Synthesis of Pd–Ni/C bimetallic materials and their application in non-enzymatic hydrogen peroxide detection

Abstract

In this study, carbon based bimetallic materials (Pd-Ni/C) were synthesized by polyol method in order to increase the hydrogen peroxide reduction catalytic activity of Pd using Ni metal. Hydrogen peroxide reduction and sensing properties of the prepared catalysts were measured by electrochemical methods. As a result, we have established that the addition of Ni at different ratios to Pd has a considerable electrocatalytic effect on H2O2 reduction. This work provides a simple route for preparation of Pd-Ni catalysts to create a very active and sensible electrochemical sensor for H2O2 sensing.

Effects of a low FODMAP diet and specific carbohydrate diet on symptoms and nutritional adequacy of patients with irritable bowel syndrome: Preliminary results of a single-blinded randomized trial

] so they try different exclusion diets. Recently, many different dietetic approaches have been tried for IBS treatment, but there are only few clinical trials. [ 7 - 10 ] Different exclusion diets or diets with low content of fat have been tried with controversial and inconsistent results. [ 11 , 12 ] A diet with increasing evidence of efficacy for the management of IBS is the low fermentable oligosaccharides, disaccharides, monosaccharides and polyols (FODMAP) diet. [ 13 - 15 ] FODMAPs can pass unabsorbed to the colon, where they increase the luminal water

Surfactant Residues in Maryland Tobacco Treated with a Fatty-Alcohol-Type Sucker-Control Formulation

Abstract

Surfactant residues (Tween 80 Esters and Tween 80 free Polyols) were determined in Maryland tobacco treated with a fatty-alcohol-type sucker-control formulation. The levels of residues in leaves decreased throughout the growing and air-curing periods, but decreased the most during the first 24 hours after treatment. Factors affecting Tween 80 residue levels included dosage and location of leaves on the plant.

The Fate of Fatty Compounds and Surfactants Used as Sucker Control Agents on Field Tobacco

Abstract

The fate of fatty compounds and surfactants used for tobacco sucker inhibition was studied with 14C-labelled materials applied to field-grown Nicotiana tabacum L. cv. Maryland Catterton plants. Residual materials recovered from test tobacco showed the following: [ 1 ] When lauric acid was used, the residual material was maintained essentially in the acid fraction. [2] When lauryI alcohol was used, a considerable part (9.7-24.8 %) was converted to the acid fraction, indicating possible oxidation of alcohol in the field; smaller amounts (7.4 to 14.8 %) were found in the ester fraction. [3] When methyl laurate was used, most (54-77 %) of the residue was recovered in the acid fraction, a small part (12.6 to 22.7 %) was found in the alcohol fraction, and the rest (10.3-23.3 %) remained in the ester fraction. [4] When Tween surfactants were used, nearly all the residual materials had been hydrolyzed to free polyol and fatty acids
