in the present study, development of new asbestos-free brake pad using lingo-cellulosic fibers and nano aluminum oxide particles was investigated. variable factors were the type of lignocellulosic materials (jute, bagass and rice husk) and the size of aluminum particles (nano and micron). these newly formulated brake pads have been tested under the grey cast iron disc. friction coefficient and ...

The finite nature of fossil-based resources, as well as the environmental awareness of the effects of their exploitation, has led to an increasing interest in finding alternative ways to produce chemicals, materials and energy. In terms of energy, biofuels are a good option for decreasing the environmental effects caused by fossil fuels, and in the last years, a great effort has been made to fi...

Lignocellulosic feedstock materials are the most abundant renewable bioresource material available on earth. It is primarily composed of cellulose, hemicellulose, and lignin, which are strongly associated with each other. Pretreatment processes are mainly involved in effective separation of these complex interlinked fractions and increase the accessibility of each individual component, thereby ...

Lignocellulosic biomass is a plentiful and renewable resource for fuels and chemicals. Despite this potential, nearly all renewable fuels and chemicals are now produced from edible resources, such as starch, sugars, and oils; the challenges imposed by notoriously recalcitrant and heterogeneous lignocellulosic feedstocks have made their production from nonfood biomass inefficient and uneconomica...

The discovery of a novel yeast with a natural capacity to produce ethanol from lignocellulosic substrates (second-generation ethanol) is of great significance for bioethanol technology. While there are some yeast strains capable of assimilating cellobiose in aerobic laboratory conditions, the predominant sugar in the treatment of lignocellulosic material, little is known about this ability in r...

The carboxylate platform is a flexible, cost-effective means of converting lignocellulosic materials into chemicals and liquid fuels. Although the platform's chemistry and engineering are well studied, relatively little is known about the mixed microbial communities underlying its conversion processes. In this study, we examined the metagenomes of two actively fermenting platform communities in...

Biorefineries combine necessary technologies between biogenic raw material and the industrial intermediates and final products. The paper represents the providing code-defined basic substances (via fractionation for the development of industrially relevant product family trees). The main focus is directed on precursor-containing biomass with preference of the carbohydrate line, in particulary o...

the moe and mor are controlled by production variables of particleboard process. now, the basic question is which of the particleboard variables is effective on bending strength property? 13 variables of internal scientific resources were measured with 100 repeats. the study steps include the following; liner regression or stepwise, genetic algorithm, and artificial neural network. the number o...

This study presents a new method to remove lignin from wheat straw (lignocellulosic) using the ozonation technique. Lignocellulosic material is complex biopolymer composed of cellulose, hemicellulose and lignin. Apart lignin, which acts as chemical resistant, lignocellulosic main resource cellulose sugars. The reaction takes place in two-phase solid–gas fluidization stainless steel reactor. foc...
