In recent years, the contamination of the aquatic environment with antibiotics, including tetracyclines, has drawn much attention. Bottom ash (BA), a residue from the biomass power plant, was used to synthesize the magnetic mesoporous silica (MMS) and was utilized as an adsorbent for tetracycline (TC) removal from aqueous solutions. The MMS was cha...

The potential of a drug delivery system of the longan seed extract (LSE) incorporated in the alginate/chitosan (Alg/CS) beads has been studied. The LSE-loaded Alg/CS beads were prepared using the ionic gelation method via the interaction between protonated amino groups of CS and negatively charged carboxylic groups of Alg. Properties of the LSE-loa...

Treatment of chronic wounds requires good monitoring for the wound infection. One of the indicators for the infected wound is the change of pH values around the wound area. In this study, the visual pH sensor from Clitoria ternatea (CT) flower was used to indicate the pH value and evaluate the wound status. The CT extract contains anthocyanins whic...

The potential of chitosan nanoparticles (CNPs) loaded with essential oil (EO) incorporated into semi-solid PVA hydrogels for use in wound management was studied. Two types of essential oil were compared including clove essential oil (CEO) and turmeric essential oil (TEO). The EO-loaded CNPs were prepared by a two-step method; oil-in-water (o/w) emu...

In order to transform waste tea leaves into a useful/valuable material for removal of Pb²⁺ ions from wastewater, MnFe2O4/biochar was synthesized. The tea waste was pyrolyzed at 500 °C to obtain the biochar. Effects of the composition of tea leaves on the physicochemical properties of biochar were evaluated. Biochar and MnFe2O4/biochar were mainly o...

The purpose of this research work was to analyze production of granulated foam glass (GFG), a lightweight aggregate used in cement concrete, using mixed waste glass as the main ingredient. The effects of foaming agent content and firing temperature on density and porosity of the GFG were studied. Dolomite mineral and tapioca gel were selected as th...

Engineered Stones were produced in a laboratory using polyester resin and domestic quart stones. Selection of these particle sizes were based on packing theory and simple Stroke’s law. From combination of both scenario, three different sizes of quartz were calculated and selected. In this scenario, the smallest size was calculated to be 6 μm while...

Bacterial cellulose (BC) nanofibers, with and without silane surface modification, were incorporated into self-reinforced poly(lactic acid) (SR-PLA) nanocomposites at 1 and 10 wt%. Disintegrated BC was combined with electrospun PLA fiber mats by film stacking and compression molding at 165 °C for 40 sec to obtain SR-PLA/BC hybrid films. The effect...

Active learning, especially STEM education, has been proven to help students develop their learning skills. Most teachers are encouraged to create activities and environments that help students to learn not only about theories involved in each lesson, but also help them to develop skills required in the 21st century. The STEM approach is used in a...

Today, the development of materials has to involve the consideration of environmental responsibility and sustainability. Therefore, more environmentally friendly products, which are biodegradable and derived from renewable resources, have been extensively established. However, in widespread applications, most bio-based polymers when used alone pres...

PLA-co-PEG copolymers synthesized through ring opening polymerization between a lactide monomer and PEG were solution-cast into films. The effect of the molecular weight of PEG and also the percentage of added PEG on the properties of the copolymers were studied. The molecular weight of PEG was 4000, 8000, and 20000 while the percentage of added PE...

a b s t r a c t Caffeine in Chiang Rai tea infusions was found to be dependent on infusion conditions (water tempera-ture and infusion time), and leaf form (non-ground or ground) but independent of tea variety and type. For non-ground leaf samples, the higher the water temperature and the longer the infusion time, the higher the caffeine concentrat...

This paper explores the potential of using rice husk powder (RHP) as a substitute or in combination with calcium carbonate (CaCO3) fillers for its application in glass fiber/polyester molding compounds. In each case, one type of filler particle was used, while three formulations of filler combinations were selected: 100% RHP, 50:50% RHP:CaCO3, and...

The effect of introducing low-cost thermoplastic fibres to a reinforcing fabric is assessed in terms of the interlaminar toughness values GIc and GIIc of laminates prepared with both polyester and epoxy resins. It is shown that the thermoplastic fibres in general will increase the GIc of the laminates but have little effect on GIIc. This situation,...

The penetration impact resistance of hybrid composites based on commingled yarn fabrics was investigated. The commingled yarn fabrics were composed of E-glass fibres (GF) and thermoplastic fibres blended together within the fibre bundles. Various thermoplastic fibres such as polypropylene (PP), polyamide (PA) and modified polyethylene terephthalate...
