  • Synthesis and Characterization of a Novel Bamboo Shaving Geopolymer Composite
  • Abstract Geopolymers are inorganic aluminosilicate materials, which have been a great research interest as a material for sustainable development. However, they possess relatively low toughness properties similar to brittle solids. The limitation may be altered by fiber reinforcement to improve their strength and toughness. This research describes the synthesis of bamboo shaving (BS) reinforced geopolymer composites and the characterization of their mechanical properties. The effect of BS content (0–2 wt. %) on the physical and mechanical properties and microstructure of metakaolin based geopolymer paste were investigated. The workability, setting time, bulk density, apparent porosity, thermal conductivity, compressive strength, flexural strength, scanning… More

  • Digestibility, Antioxidant and Anti-Inflammatory Activities of Pecan Nutshell (Carya illioinensis) Extracts
  • Abstract Phenolic compounds are related to high biological activity, avoiding oxidation in food and human systems. Nutshells are by-products derived from the pecan nut processing that contain important amounts of phenols which biological activity must be studied. This research aimed to evaluate the antioxidant (DPPH, ABTS, FRAP and hemolysis) and anti-inflammatory activities of shell extracts from pecan nuts harvested during the crop production cycle 2018 and 2019, as well as the in vitro digestibility of their phenolic compounds, including flavonoids. Results showed that extracts from the crop production cycle 2018 obtained the highest yield, while those from 2019 contained the highest… More

  • Pathways for Sustainable Utilization of Waste Chicken Eggshell
  • Abstract Chicken eggshell is one of the most common wastes generated from households, restaurants and other food processing outlets. Waste Chicken Eggshells (WCES) also constitutes an environmental nuisance and ends up discarded at dumping site with no consideration of further usage. The main constituent of WCES is calcium carbonate from which calcium or calcium oxide can be extracted for various applications. This current effort reviews recently published literature on the diverse applications of WCES. The considered utilization avenues include catalysts for biofuel production, construction industry, wastewater purification, industrial sector, food industry, medical, and agricultural applications. The specific areas of application apart… More

  • Research of Mechanical and Thermal Properties of Composite Material Based on Gypsum and Straw
  • Abstract This article is focused on the investigation of the mechanical and thermal properties of composite material that could be used for the production of plaster or plasterboards. This composite material is made of gypsum and reinforcing natural fibers. The article verifies whether this natural reinforcement can improve the investigated properties compared to conventional plasters and gypsum plasterboards made of pure gypsum. From this composite material, high-strength plasterboards could then be produced, which meet the higher demands of users than conventional gypsum plasterboards. For their production, natural waste materials would be used efficiently. As part of the development of new building… More

  • Effects of Planting Density of Rubber Tree Clone (RRIM 2020 Clone and RRIM 2025 Clone) Wood to Particleboard Properties
  • Abstract The depletion of log resources encourages research into alternative ways to sustain the wood supply. Therefore, the 4-year-old Rubber Research Institute of Malaysia (RRIM) clones series, RRIM 2020 and RRIM 2025, were chosen as potential raw materials for particleboard in this study. The purpose of this study was to assess the effects of planting density and rubber tree clones on the mechanical and physical properties of single-layer particleboard. The planting densities used were low, moderate-low, moderate-high, and high, representing 500, 1000, 1500, and 2000 trees/ha, respectively. Prior to manufacturing, the RRIM 2000 series clone trees were harvested, cut, chipped, flaked,… More

  • One Step Regioselective Acylation of Polyphenolic Wood Extractive and Its Application for Wood Treatment
  • Abstract This study evaluated the methods of grafting commercial catechin with fatty acids, namely capric acid (C10), lauric acid (C12), and myristic acid (C14) through esterification. Specimens of beech wood (Fagus sylvatica L.) were impregnated with catechin and modified catechin-fatty acids, separately, at a 5% concentration diluted in ethanol using vacuum pressure treatment and subjected to leaching. The weight percentage gain before leaching (WPG), after leaching (WPGAL), and weight loss due to leaching (PL) were investigated. Both leached and unleached samples were tested against white-rot fungi (Trametes versicolor) in Petri-dishes for twelve weeks. Results show that samples treated with modified catechin-fatty… More

  • A Review of Various Sources of Chitin and Chitosan in Nature
  • Abstract Chitin was first discovered by its name from the Greek word “chiton”, which means “mail coat”. It is indeed a polysaccharide made up of naturally occurring acetyl-D-glucosamine monomers. Hatchett was the first researcher who extracted chitin from the shells of mollusks (crabs and lobsters), prawns, and crayfish in 1799. Later in 1811, Henri Braconnot discovered chitin in the cell walls of mushrooms and called it “fungine”. Chitin and chitosan are abundant in the biosphere as essential components of many organisms’ exoskeletons and as by-products of the global seafood industry. The biopolymer must be deacetylated before chitosan can be produced. It… More

  • Structure, Dynamic-Mechanical and Acoustic Properties of Oil Palm Trunk Modified by Melamine Formaldehyde
  • Abstract The performance of oil palm trunk wastes from Banjarbaru of South Kalimantan was improved with the help of chemical modification in a two-step treatment. The first was formalization with formaldehyde solution with varying pH, and the second was impregnation with melamine-formaldehyde resin under 5 bar pressure for an hour. In these processes, the samples were cured at 120°C for 10 min and then dried in an oven at (103 ± 2)°C in order to attain a moisture content of less than 6%. These treatments improved the physical properties (density, moisture content, and volume swelling), mechanical resistance, dynamic-mechanical and acoustic performance… More

  • Extraction Hydrolysates from Larimichthys Polyactis Swim Bladder Using Enzymatic Hydrolysis
  • Abstract As a kind of biopolymer, hydrolysates of fish swim bladder, safer than those of land mammals, are widely used in food, cosmetics as well as pharmaceutical and biomedical fields for their biocompatibility, biodegradability, and weak antigenicity. To enhance hydrolysate production, in this paper, the papain and alcalase hydrolysis processes of larimichthys polyactis swim bladder were optimized with orthogonal experiments. With 89.5% hydrolysate yield, the optimal processing conditions for alcalase were solid-liquid ratio of 1:30, enzyme concentration of 0.7%, and extraction time of 6 h. As for papain, under the optimal processing conditions: solid-liquid ratio of 1:20, enzyme concentration of 0.5%,… More
