1. Enzyme-based Colorimetric and Potentiometric Biosensor for Detecting Pb (II) Ions in Milk
The aim of the present work was to study a simple colorimetric and potentiometric biosensor based on urease inhibition by Pb (II) ions for its estimation in milk samples. Urease immobilized on nylon membrane by hydrosol gel method was used as the biocomponent to demonstrate the metal effect on the enzyme activity using phenol red as the pH indicator. A lower

2. The use of the oregano (Origanum vulgare L.) essential oil and hydrosol in green olive fermentation
The effect of oregano the (Origanum vulgare L.) oil at the levels of 0.05, 0.1 and 0.3% and oregano hydrosol on the physicochemical, microbiological and sensory characteristics of the green olive (Edremit variety) fermentation was investigated. The initial pH of the oregano oil added samples were higher than the other treatments, which were above 5.8. The hi

3. Ultra-low friction coefficient between Si3N4-Al2O3 in water. / Ultra-baixo coeficiente de atrito entre o par cerâmico Si3N4-Al2O3 em água.
Neste trabalho, foi investigado o comportamento tribológico dos pares cerâmicos aluminanitreto de silício no deslizamento em água e em uma suspensão de sílica coloidal em água (hidrosol). O objetivo foi verificar a possibilidade de atingir um coeficiente de atrito da ordem de unidades de milésimos, aqui chamado de ultra-baixo coeficiente de atrito (U

5. Certification of Probability of Sterilization of Liquid by Filtration
Four types of hydrosol filters, two reusable (diatomaceous cylinder and fritted-glass funnel) and two disposable (asbestos pad and membrane filter) were challenged with a heavy bacterial suspension to assess their ability to produce sterile filtrates. Two of the four diatomaceous earth filters, the four fritted-glass funnels, and all of the asbestos pads tes
