Abstract:

The in vitro wood decay abilities of Ganoderma lucidum (W. Curt.: Fr.) Karst. and G. tsugae Murr. were studied using the following woods in agar block decay chambers: Vitis vinifera L., Quercus hypoleucoides A. Camus, Prosopis velutina Woot., Abies concolor (Gord. & Glend.) Lindl. ex. Hildebr., and Pseudotsuga menziesii (Mirb.) Franco. Grape wood lost the most weight while mesquite the least. Ganoderma lucidum isolates generally caused greater weight loss of all woods than did G. tsugae isolates. The range of the percent weight losses varied with the wood. Both Ganoderma species caused sim

Abstract:

Recently, different methods have been proposed to develop wood materials, termed “densified woods”, with density increment and improvement in mechanical proprieties. Almost all the proposed methods involve the use of reducing agents and strong bases. In this work, a new method has been developed involving the use of less polluting agents. The formation of densified woods is divided into two steps: delignification involves the removal of lignin, hemicelluloses, and shorter chains of cellulose, whereas densification involves the plastering of the delignified woods. The obtained materials showed

Abstract:

Wood has many uses as raw material and after being processed. Since the use of wood as raw material is limited, the interaction of physical and chemical processes with technological developments has led to new products and new areas of use. Transparent wood production, for example, has emerged to provide maximum efficiency from heat and light. In this study, sodium chlorite and deep eutectic solvents (DES) obtained from choline chloride and lactic acid were used. In the production of transparent wood, 1- and 2-mm thick beech wood veneers (Fagus orientalis L.) and two-component transparent epox

Wood is an attractive and inherently sustainable alternative to many conventional materials. Recent research on improving wood mechanical strength emphasizes wood densification through the partial removal of lignin and hemicelluloses, therefore the chemical and physical properties of delignified and densified wood require further investigation. In this study, poplar wood samples were subjected to alkali and maleic acid hydrotropic delignification with varying degrees of lignin and hemicellulose removal followed by hot pressing, and the microstructure, chemical properties, and dimensional stabi

The objective of this study was to assess the causes of the problems arising in the CBC kraft cooking of several types of hardwood chips particularly in view of high dry matter but also in view of chip thickness and character of wood.High dry matter of processed chips influences negatively delignification. Similar effect on delignification is achieved by wood character (anatomic and morphological properties of cell elements, chemical composition, portion of heart and sapwood).Chips thickness has the most significant impact on delignification process comparing to other monitored characteristics

The emergence of transparent wood as a viable alternative to traditional glass has sparked considerable interest in recent research endeavors. Despite advancements, challenges persist in the delignification methods and wood species utilized in prior studies. Therefore, this study delves into the potential of Brazilian eucalyptus wood for transparent wood production through the kraft pulping process. Delignification was carried out in a laboratory setting, replicating the kraft process with varying reaction times (15, 30, 45, and 60 min). The resulting delignified wood veneers were impregnated

Abstract:

Oxygen-alkaline pulping is a sulphur-free chemical pulping process, which has a potential to replace the kraft process as an environmentally more viable alternative. However, there are some drawbacks to the process, which have so far prevented it from commercialization. The penetration of oxygen into the structure of wood chips and rather severe degradation of carbohydrates are the main problems that result in high reject contents and low pulp strengths. In this study, wood chips, after presoaking in a 0.2% solution of alkali, were mechanically treated in a compression screw feeder with the ai

Abstract:

<p>Over the years, hydrogen peroxide has been used to improve the brightness of pulp at the end of a bleaching sequence. However, the degree of delignification achieved by a hydrogen peroxide stage is usually modest. That is because in alkaline condition the hydroperoxy anion reacts with chromophores in pulp as a nucleophile that does not oxidize residual lignin to a significant extent. In order to enhance the reactivity of hydrogen peroxide as an oxidant, a binuclear manganese complex Mn(IV)2-Me4DTNE was added. As a result, the degree of delignification was significantly improved, while at th
