The demand for eco-friendly materials in many sectors is due to the age-long usage of synthetic materials, which has so negative impacts on environment, high energy consumption, and health concerns. physical, mechanical, morphological, thermal properties woven kenaf fibre reinforced bio-epoxy composites are investigated this study. bio-composites were produced utilizing a manual lay-up process with varying loading percentages 30%, 35%, 40%. Pure Bio-epoxy also prepared as reference....
Dye-sensitized solar cell (DSSC) is a third generation of cell, which has been pursued by numerous researcher to increase its efficiency, stability, and compatibility with our surrounding. One advancement usage natural product or organic material replace an artificial sensitizer such as ruthenium sensitizer, expensive, difficult synthesize own noxiousness. A mangosteen (Garcinia mangostana) pericarps easily obtained from eaten fruits. Mangosteen fruits are mainly grown in Southeast Asia...
Thermosetting epoxies are low-density polymers with excellent adhesion, mechanical properties, and resistance to environmental degradation. They widely used as molds castings for manufacturing, protective coatings, reinforcement material aircraft. However, polymer brittleness is a major disadvantage preventing its widespread application. The addition of filler materials such nanoparticles has attracted considerable attention. Using biocomposite derived from natural, renewable sustainable...
Dye-sensitized solar cells (DSSCs) are fabricated using natural sensitizers extracted from rengas (Gluta spp.) and mengkulang (Heritieraelata) wood. The a cold extraction the Soxhlet methods. This paper presents results of analysis optical characteristics via ultraviolet–visible spectrophotometry Fourier transform infrared spectroscopy. band gap highest occupied molecular orbital (HOMO)–lowest unoccupied (LUMO) levels each investigated sensitizer calculated on basis analyzed data collected...
Dyes extracted from rengas (Gluta spp.) and mengkulang (Heritiera elata) wood were investigated as sensitizers in dye-sensitized solar cells (DSSCs). Three types of sensitizers, including individual sensitizer, mixture co-sensitizer, exhibited different patterns absorption properties under UV-Vis spectroscopy. The incident photon-to-current efficiency (IPCE) was analyzed via spectral response to examine the generation photocurrent. Because sensitized DSSCs obtained broader spectra, they...
Polymer blends is a well-established and suitable method to produced new polymeric materials as compared synthesis of polymer. The combination two different types polymers will produce unique material, which has the attribute both polymers. aim this work analyze mechanical morphological properties bio-phenolic/epoxy polymer find best formulation for future study. Bio-phenolic/epoxy were fabricated using hand lay-up at loading bio-phenolic (5 wt%, 10 15 20 25 wt%) in epoxy matrix whereas neat...
Due to the growing trend promote alternative materials, use of cellulosic fibers as filler/reinforcement in polymer composites has increased popularity. The objective this research is determine effect flax fabric loading on physical and mechanical properties bio-phenolic/epoxy composites. were fabricated using hand lay-up method a mould cured hot press. Bio-phenolic/epoxy blend was control. sample tested for physical, tensile, flexural, impact morphological properties. result showed that,...
The decay resistance and hyphae penetration of bamboo Gigantochloa scortechinii decayed by white brown rot fungi were investigated using scanning electron microscope (SEM). grown in natural stand from three different age classes 0.5, 3.5, 6.5 years was harvested, oven dried, sterilised, exposed to agar media containing 4% malt extract 2% technical (no. 3) under laboratory condition for 8 weeks. deterioration expressed as percentage weight loss, the measured according ASTM D 2017-81 (1986)....
This study examined and described the optical photovoltaic (PV) characterizations of Fruit Areca catechu (pinang) as a new type organic sensitizer. Recent reports stated that including chenodeoxycholic acid (CDCA) in dye improves performance dye-sensitized solar cells (DSSCs). The effectiveness PV was investigated by applying it DSSC. absorption spectra indicated natural dyes with CDCA has an excellent stabilizing ability. Fourier-transform infrared existence carboxylic hydroxyl functional...
The influence of flax fibre loading on the dynamic thermal and mechanical characteristics composites was investigated in this work. Flax were fabricated at 30 (F-30), 40(F-40) 50(F-50) wt% loading. As a control, bio-phenolic/epoxy polymer blend (P-20) containing 20% bio-phenolic made. findings suggest that incorporation into led to an enhancement properties experimental sample. glass transition temperature (Tg) identified via analysis be between 60°C 85°C. Aside from that, cole-cole plot...
The decay resistance of acetylated rattan was compared to beech and pine wood. Calamus manan grown under rubber tree canopy different ages (10 13 years) levels by reaction times (0·25–24 h) subjected against the white brown rot fungi, T. versicolor C. puteana. Protection occurred at 13·4 9·0% weight gains (WGs) 13·5 10·3% WG puteana for 10 years old respectively.
Usage of natural product in improvement dye-sensitized solar cell (DSSC) have been look upon research field. There is numerous different type nature was used as dye but the performance DSSC with are low efficiency compare to Ruthenium (II) due anchoring strength between molecule TiO2 surface. This paper about an experiment device sensitizer Mangosteen Graphene Oxide catalyst. The highest graphene oxide (GO) concentration 0.50 mg/ml obtained this 0.40% short-circuit current density (Jsc) =...
Hydrothermal treatment is an efficient and environmentally friendly method of enhancing the dimensional stability durability wood. The destructive effects formic acetic acids generated during thermal treatment, on other hand, are known to have a negative impact wood strength. As result, hydrothermal in different buffered media (acidic, neutral, alkaline buffer) was performed this study mitigate acids. heating media, acidic buffer (pH 4 6), 8 10), tap water 7.43) were used treat rubberwood at...
