    Physicochemical Properties of Combustion Ashes of Some Trees (Urban Pruning) Present in the Neotropical Region

    John Freddy Gelves-Díaz1,*, Ludovic Dorkis2, Richard Monroy-Sepúlveda1, Sandra Rozo-Rincón1, Yebrail Alexis Romero-Arcos1

    Journal of Renewable Materials, Vol.11, No.10, pp. 3769-3787, 2023, DOI:10.32604/jrm.2023.029270

    Abstract Secondary lignocellulosic biomass has proved to be useful as an energy source through its oxidation by means of combustion processes. In accordance with the above, in this paper, we wanted to study the ash from urban pruning residues that are generated in cities in the Neotropics. Species such as Licania tomentosa, Azadirachta indica, Ficus benjamina, Terminalia catappa, Leucaena leucocephala, Prosopis juliflora and Pithecellobium dulce were selected because they have been previously studied and showed potential for thermal energy generation. These materials were calcined in an oxidizing atmosphere and characterized by X-ray diffraction and fluorescence, scanning electron microscopy with microchemistry, BET… More > Graphic Abstract

    Journal of Renewable Materials, Vol.11, No.1, pp. 473-490, 2023, DOI:10.32604/jrm.2022.023548

    Abstract Drop weight impact tester was used to accurately measure the bending impact resistance of various parts of Phyllostachys edulis, commonly known as moso bamboo, with a growth cycle of 3–8 years. Cellulose crystallinity in the bottom (B), middle (M) and top (T) of bamboo at different ages was calculated using peak height analysis in X-ray diffraction. Heatmap of Spearman correlation analysis was used to represent the correlation between chemical composition and impact mechanics. The breaking load (BL), fracture energy (FE) and impact deflection (ID) of 3–8-yearold bamboo were found to be in the range of ~670–2120 N, ~5.17–15.55 J, and… More > Graphic Abstract

    Properties and Applications of Bamboo Fiber–A Current-State-of-the Art

    Chen Chen1,2, Haitao Li1,2,*, Assima Dauletbek1,2, Feng Shen3, David Hui4, Milan Gaff5, Rodolfo Lorenzo6, Ileana Corbi7, Ottavia Corbi7, Mahmud Ashraf8

    Journal of Renewable Materials, Vol.10, No.3, pp. 605-624, 2022, DOI:10.32604/jrm.2022.018685

    Abstract Fibers are used in many forms in engineering applications–one of the most common being used as reinforcement. Due to its renewable short natural growth cycle and abundance of bamboo resources, bamboo fiber has attracted attention over other natural fibers. Bamboo fiber has a complex natural structure but offers excellent mechanical properties, which are utilized in the textile, papermaking, construction, and composites industry. However, bamboo fibers can easily absorb moisture and are prone to corrosion limiting their use in engineering applications. Therefore, a better understanding of bamboo fiber is particularly important. This paper reviews all existing research on the mechanical characterization… More >

    Canola and Oat Forage Potential Evaluation in Four Early Planting Dates

    Juan Isidro Sánchez-Duarte1, David Guadalupe Reta-Sánchez1,*, José Antonio Cueto-Wong1, Arturo Reyes-González1, Esmeralda Ochoa-Martínez1

    Phyton-International Journal of Experimental Botany, Vol.88, No.4, pp. 435-448, 2019, DOI:10.32604/phyton.2019.07512

    Abstract Canola and oat forage potential may be affected by climatic conditions when sown early. The objective of this study was to evaluate the forage canola and oat potential in four early sowing dates (September 11 and 25; October 9 and 23) during the 2012-2013 and 2013-2014 cycles in Matamoros, Coahuila, Mexico. Growth cycle duration, chemical composition, dry matter (DM), crude protein (CP), and net energy for lactation (NEL) yields were determined. High temperatures and long photoperiods affected crops seeded on September 11, accelerating growth and reducing canola (26.6%-31.7%) and oat (15.8%) DM yields. As of September 25, canola cv IMC… More >

    Effects of plant height and row spacing on kenaf forage potential with multiple harvests

    Reta-Sánchez DG1, JS Serrato-Corona2, HM Quiroga-Garza1, A Gaytán-Mascorro1, JA Cueto-Wong1

    Phyton-International Journal of Experimental Botany, Vol.84, No.2, pp. 262-271, 2015, DOI:10.32604/phyton.2015.84.262

    Abstract Kenaf (Hibiscus cannabinus L.) forage potential can be enhanced through its regrowth capacity and higher production in narrow rows. A field experiment was conducted in Matamoros, Coahuila, Mexico, during 2 growing seasons (2004 and 2005) to study the effects of plant height and row spacing on kenaf forage potential with multiple harvests. This study evaluated the effects of (1) 2 plant heights at cutting (1.0-1.2 m and 1.8-2.0 m) and (2) 4 inter row spacings (0.19, 0.38, 0.57 and 0.76 m) using a 2 x 4 factorial arrangement of treatments in a completely randomized block design with 4 replications.

    Lara-Rivera AH1, MA Ruiz-Lopez1, R Rodriguez-Macias1, C Soto-Velasco1, PM Garcia-López1, L Barrientos-Ramirez2, JF Zamora-Natera1

    Phyton-International Journal of Experimental Botany, Vol.86, pp. 89-96, 2017, DOI:10.32604/phyton.2017.86.089

    Abstract Given that the agronomic potential of Lupinus angustifolius is not yet known in Mexico, we evaluated the yield and chemical composition of six L. angustifolius varieties (Haags Blaue, Boregine, Borlu, Probor, Sonate, and Boruta) in Zapopan, Jalisco, Mexico. Studies were conducted during the Autumn-Winter seasons of 2012-2013. We identified the varieties with the highest and lowest protein concentrations and analyzed their respective amino acid profiles. The major protein constituents were determined by electrophoresis (SDS-PAGE). This experiment was conducted in an agricultural facility at the University of Guadalajara using a completely randomized block design and four replicates. The highest grain yield… More >
