Thermodynamic Analysis of the Hydrogen Production from Ethanol: First and Second Laws Approaches

open access: yesInternational Scholarly Research Notices, Volume 2012, Issue 1, 2012., 2012
A thermodynamic analysis of hydrogen production from ethanol steam reforming (ESR) is carried out in the present paper. The influence of reactants molar ratio feed into the reforming stage (2.5 < molWater/molEtOH < 8), temperature (573 to 1173 K) and pressure (1 < P < 10 atm) over equilibrium compositions is studied.

Scientific opinion on the exposure of children and adolescents in the Republic of Croatia to acrylamide from food

open access: yesFood Risk Assess Europe, Volume 4, Issue 1, January 2026.
Summary Acrylamide is a natural by‐product of the reaction that occurs during the baking or frying food at temperatures above 120°C in industry and in households. The main mechanism of acrylamide formation in food is the Maillard reaction, in which the free amino acid asparagine, which is found in many types of cereals and potatoes, reacts with ...

Conductometric Study of Complex Formation Between Cu(II) Ion and 4‐Amino‐3‐ethyl‐1,2,4‐triazol‐5‐thione in Binary Ethanol / Water Mixtures

open access: yesJournal of Chemistry, Volume 5, Issue 3, Page 551-556, 2008., 2008
The stability constant, Kf, for the complexation of copper(II) ion with 4‐amino‐3‐ethyl‐1,2,4‐triazol‐5‐thione (AETT ) in 0, 20, 40, 60 and 80 (v/v) % ethanol‐water mixtures were determined conductometrically at different tempratures. Stability constant of resulting 1:1 complexes were being larger by increasing of temprature and ethanol percent ...
