Abstract Graft copolymerization of methyl acrylate (MA) and acrylonitrile (AN) onto acacia cellulose was carried out using free radical initiating process in which ceric ammonium nitrate (CAN) used as an initiator. The optimum grafting yield determined by the certain amount (AGU), mineral acid (H 2 SO 4 ), CAN, MA, AN at 0.062, 0.120, 0.016, 0.397, 0.550 mol L −1 , respectively. poly(methyl acrylate‐ co ‐acrylonitrile)‐grafted obtained 55°C after 2‐h stirring, purified acrylic...
Abstract The hypothesis that seaweed farming contributes to carbon burial below the farms was tested by quantifying rates in 20 distributed globally, ranging from 2 300 years operation and 1 ha 15,000 size. This involved combining analyses of organic density with sediment accumulation rate sediments relative reference beyond farm and/or prior operation. One every four sampled set over environments export, rather than retain materials. For were placed depositional environments, where could be...
Two compounds based on the ethyl cellulose having azobenzene side chain mesogenic units were prepared and structures of cellulosic liquid crystals confirmed by Fourier transform infrared (FTIR) nuclear magnetic resonance (NMR) spectra. Liquid-crystalline properties characterized differential scanning calorimetry polarizing optical microscopy in which compound 4a shows a columnar phase 4b semectic A phase. The absorption spectra display high-intensity π–π* transition at about 364 366 nm for...
Auricularia cornea, or wood ear mushroom (WEM), is an edible macrofungus that popular as a delicacy and for various biological activities. This study aims to determine the nutrient composition, in vitro antioxidant activities effect on postprandial blood glucose human subjects after consuming instant noodles incorporated with 5% WEM powder. The proximate composition of powder was 9.76% moisture, 2.40% ash, 7.52% protein, 0.15% fat, 37.96% crude fibre, 42.21% carbohydrate, total dietary fibre...
Abstract Seaweed has been used in many industries, whether directly or its extract. Padina sp . is one of the understudied species brown seaweed. Brown seaweed have alginate embedded their cell wall which a type hydrocolloids and can be industries applications including development biofilms. The main objective this current study to develop biofilms using extracted from incorporated with calcium chloride at different concentrations. Prior that, functional groups extract were determined. Then,...
Petroleum-based plastics are mass produced to meet customers’ demand due their low cost and versatility. However, plastic waste has become a serious environmental problem. Hence, degradable from renewable sources (e.g. biomass) now trending for “green” properties. In this paper, properties of biofilms made whole seaweed (WS), Kappaphycus sp. pure kappa-carrageenan powder (PC) were compared. Glycerol, as plasticizer, was added at differing amounts (1%, 2%, 3%, 4% 5%, v/v) appearance, physical...
Abstract Plastic pollution has become one of the most concerning problems globally due to excessive use one-time plastics. However, bioplastics could be answer help combat this problem as they are readily biodegradable. Development was done by mixing seaweed biomass into distilled water at specific ratio, using glycerol plasticizer. Bioplastics were developed ratio 100:0, 75:25, 50:50, 25:75, and 0:100 K. alvarezii commercial sodium alginate ratio. Characterization based on their appearance,...
Road degradation is a common problem in Malaysia which caused by weather changes, expanding loads as well the effects of ageing, moisture and temperature results high maintenance expenses on conventional bitumen pavement. Therefore, it has been recommended modification substitute technique to address this issue extend pavement’s lifespan. This study addresses inadequacy existing solutions focusing direct mixing approach use pre-treatment using chemical solvent some additives specifically...
Abstract Borneo is the centre of diversity genus Durio (family: Malvaceae; local name: durian). Durian fruit known to contain high amounts major bioactive compounds (as antioxidants) such as anthocyanins, carotenoids, polyphenols and flavonoids. Two types wild durian species, namely kinabaluensis Kosterm. & Soegeng (durian tupoloh) oxleyanus Griff. sukang) were studied. The 80% methanolic extracts flesh, seed peel (mesocarp exocarp) analysed for antioxidant activities, total phenolic...
Abstract Tea Tree oil (TTO) contains beneficial properties such as antibacterial, antimicrobial, antiviral and anti-fungal. Whereas, the medium chain fatty acids in Virgin Coconut (VCO) able to protect hair follicles from heat, restoring hair’s moisture other damage. This paper describes physical of seven shampoo formulations containing differing amount TTO VCO. The essential oils applied these were extracted fresh tea trees using steam distillation method VCO was produced fermentation...
Watercress (Nasturtium officinale sp.) from the Brassicae family contains phenethyl glucosinolates (gluconasturtiin) as main glucosinolate (GLS). The enzymatic hydrolysis products by naturally-occuring myrosinase produced isothicyanate (PEITC) which reported to possess anti-carcinogenic activity. Depending on several factors, its counterpart, nitrile (PEN) can also be formed product. This study investigated effects of adding ascorbic acid and Fe2+ ions at different concentration...
