Abstract Activated carbon preparation from sugarcane leaves and rice straw by carbonization (250°C–400°C) and activation at 500°C were studied. The effects of pre-oxidation, hydrolysis of derived charcoals by boiled KMnO₄ aqueous solution were evaluated. The derived charcoals products were pretreated using oxidation-hydrolysis with 1–5 wt.% KMnO₄ at 100°C and then activated at 500°C. The derived charcoal and activated carbon products were characterized by FTIR, XRD, SEM-EDS and BET. Iodine number and methylene blue number of derived products were also used for the analysis of the products. It was found that fabricated charcoal materials made at 350°C–400°C possess… More > Graphic Abstract

Abstract Indonesia is one of the largest coconut-producing countries in the world. The utilization of coconut shell waste into briquettes will increase the selling value and become a great export opportunity. However, the effect of adhesives on the quality of coconut shell charcoal briquettes made using screw extruder machine has not been widely studied. This study aims to determine the effect of adhesive type on the quality of coconut shell charcoal briquettes. The process of fabricating briquettes in this study included crushing, mixing, blending, pressing, and drying. In the mixing process, 3 types of adhesives were… More > Graphic Abstract

Abstract Potato propagation through tubers and seed is an inefficient way of propagation thus we propose an alternative method in this study which is in vitro propagation. Plantlets were raised from True Potato Seeds (TPS) in test tubes containing 10 mL of Murashige Skoog (MS) medium. Subculturing was done after every 21 days and after four subsequent subculturing, when there was an adequate quantity of stock material, uninodal cuttings of about 3–4 mm in length were prepared from in vitro proliferated potato plants by excising leaves of 1–2 mm on each side of the node. Prepared uninodal cuttings… More >

Abstract Soil heavy metal pollution is becoming more and more serious. Biomass charcoal application can play an important role in alleviating the toxicity of heavy metals in soils. Compared with other biochar, bamboo charcoal has more unique properties and may have a unique effect on heavy metal pollution. Zhejiang Province of Southeastern China is rich in bamboo resources. However, few studies related to bamboo charcoal application for heavy metal remediation in farmland were reported. In this study, four treatments with different amounts of bamboo charcoal application were set up through a field experiment, namely BC0 (no… More >

Abstract The aim of the present study was to investigate the efficiency of the encapsulation-dehydration technique for cryopreservation of Cyrtopodium hastchbachii Pabst seeds. Immature seeds of this species were cryopreserved by an encapsulation-dehydration technique. Seeds of five immature pods, 120 days after pollination, were encapsulated in 3% calcium alginate matrix and pretreated in liquid medium supplemented with 0.08 M sucrose (24 h), 0.15 M sucrose (24 h), 0.25 M sucrose (48 h), 0.5 M sucrose (24 h) and 0.75 M sucrose (24 h) in shaker at 60 rpm. Alginate beads were dehydrated 5 h in silicagel and More >

Abstract We evaluated the effect of cold storage and fire-related cues on seed germination of Arctostaphylos pungens HBK (Mexican Manzanita), a common shrub in poorly managed pine-oak forests in Durango, Mexico. Because this shrub has a high density in previously burnt forests, we investigated the effect that high temperatures, smoke and charcoal might have on seed germination of this species. Seeds were collected fresh from the shrubs. The highest germination was 30% for seeds that had been cold stored, heat shocked, past through smoke and watered with diluted charcoal. More >
