Control and formulated glue-mixes with tobacco particles additive were used to bond Falcataria moluccana veneers into 3-ply plywood. The effect of varying amounts of tobacco particles (4, 8 and 12%) in the glue-mixes on shear strength, wood failure and subterranean termite (Microcerotermes losbañosensis) resistance of the plywood was examined. An increase in shear strength and wood failure up to 8% tobacco particles loading was observed compared with plywood that used commercial glue formulation. Based on shear strength and wood failure, panels containing 4–8% tobacco particles would pass the requirements of PNS ISO 12466-2. Termite resistance at 12% tobacco particles improved by 43% compared with the control. Thus, tobacco particles can be considered as a more beneficial alternative glue-mix additive in plywood production.","PeriodicalId":14414,"journal":{"name":"International Wood Products Journal","volume":"12 1","pages":"51 - 57"},"PeriodicalIF":1.1,"publicationDate":"2020-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/20426445.2020.1830347","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46841369","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The purpose of the study was to assess the economic feasibility of on-site wood pellet processing for bioenergy market. The benefit–cost model was used to estimate the nett return over the projected investment period. Monte Carlo simulation was performed for the possible range of nett returns and to identify the effect of stochastic variables on profitability. The simulation results showed positive nett return from both biomass production and processing of pellets. The sweetgum yield, market price of biomass and pellet, and projected volume of pellets had the greatest positive effect on profitability. The results will help to make pelletizing readily available to those who are looking to make the switch and go green by using alternative and renewable energy.","PeriodicalId":14414,"journal":{"name":"International Wood Products Journal","volume":"11 1","pages":"173 - 188"},"PeriodicalIF":1.1,"publicationDate":"2020-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/20426445.2020.1816766","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47524292","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Reflecting the richness of Anatolian culture and architecture, each of these buildings is an important part of the culture of Anatolian timber construction.

Three frequencies (0.1, 1.0 and 10 Hz) were used over a temperature range of −150°C to +150°C. All the wood species showed tan δ peaks corresponding with secondary relaxations in the expected range. The low temperature (γ peak) was seen at −115°C to −83°C, differing between species and with frequency. β peaks relating to hemicellulose relaxations in association with water molecules were observed, at two locations for Scots pine and three locations in hardwoods. The α peak for lignin lay outside the temperature range studied. Differences in β peaks are proposed to relate to the composition of hemicellulose, and be influenced by structure and level of heterogeneity in the amorphous polymer domains; differing between the wood species studied, which is in-line with currently proposed cell wall polymer models.","PeriodicalId":14414,"journal":{"name":"International Wood Products Journal","volume":"11 1","pages":"189 - 203"},"PeriodicalIF":1.1,"publicationDate":"2020-08-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/20426445.2020.1799910","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48184718","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Most of this work was restricted to shades of blue-green, brown, white, and black zone lines. Modern spalting has added in shades of red and blue. The current colour palette of spalting fungi has the potential to be expanded through the use of Scytalidium ganodermophthorum, a fungal pathogen and suspected soft rot of wood, which produces multiple colours of pigment throughout its growth, including yellow and purple. However, no previous study has tracked colours of the extracted fungal pigment across time. This study showed significant colour change of extracted fungal pigments across 36 weeks of growth, transitioning over time from bright yellow to green shades, before finally becoming slate purple. This diversity of hues increases the colours available to artists working with spalting pigments, and has the potential to expand the art form.","PeriodicalId":14414,"journal":{"name":"International Wood Products Journal","volume":"12 1","pages":"34 - 39"},"PeriodicalIF":1.1,"publicationDate":"2020-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/20426445.2020.1780543","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42250773","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Sawdust and activated carbon were investigated as bio-adsorbents for boron removal from freshwater. Sawdust showed the highest boron adsorption uptake (1.58 mg g−1) compared to activated carbon (0.97 mg g−1). This higher capacity was caused by the presence of hydroxylic, carboxylic, and polyphenolic groups. FTIR analysis before and after adsorption of boron suggested that the mechanism involved in the boron removal might be complexation.
