Pre-formulation Studies on Moisture Absorption in Microcrystalline Cellulose Using Differential Thermo-Gravimetric Analysis

Determination of Composi Tion of Cellulose and Lignin Mixtu Res Using Thermo Gravimetric Analysis (tga)

The proportional composition of cellulose, hemicellulose, lignin and minerals in a biomass plays a significant role in the proportion of pyrolysis products (bio-oil, char, and gases). Traditionally, the composition of biomass is chemically determined, which is a time consuming process. This paper presents the results of a preliminary investigation of a method using thermo-gravimetric analysis f...

Effect of Nano Silica on Moisture Absorption of Polyurethane Clear Coats as Studied by EIS and Gravimetric Methods

Electrochemical impedance spectroscopy and gravimetric methods were carried out to analyze water uptake of thin polyurethane films separately filled with either hydrophobic or hydrophilic nano-silica. Correspondingly the impedance spectra and gravimetric data were interpreted in terms of movement of water within the coating and/or to the coating/metal interface. Although the obtained results fr...

Thermal analysis of microcrystalline cellulose prepared from esparto grass

Alfa fibres are extracted from the plant Stippa tenacissima, or esparto grass (alfa is the Arab name for esparto), and grows in the dry regions of North Africa. It belongs to the graminacies family and grows to a height of about 1 m. These fibres are mostly used in the production of paper. Recently, they have been used as reinforcement in the production of biodegradable composites. The aim of t...

Enthalpy of Combustion of Microcrystalline Cellulose

A test substance with characteristics and properties similar to those of cellulose· based solid waste products is needed to calibrate calorimeters and combustors which will be routinely burning these materials to determine their calorific values precisely for use in commerce. Microcrystalline cellulose was found to be a good calibrant for this purpose. The enthalpy of combustion of microcrystal...
