Research ArticleOpen accessIn the keywordsAdhesion and Hardness Evaluation of Modified Silicone-Dammar as Natural Coating MaterialsR. Zakaria, A. H. AhmadProblem statement: Dammar is a natural resin that used anciently in varnish production. The use of dammar natural resin in coating is limited by undesirable properties for application in coating where it is considered very brittle. Due to dammar's brittle nature, an aged dammar coating can be easily scratched or abraded. Approach: Dammar natural resin could be modified into Silicone-Dammar … …American Journal of Applied Sciences, Vol. 9, Issue 6 · 20 Mar 2012 · 7,630 accessesView PDF Cite

Research ArticleOpen accessIn the abstractUnderstanding Hybrid Additive Manufacturing of Functional DevicesSantosh Kumar Parupelli, Salil DesaiThe fabrication of electronic components in three-dimensional space is critical for building multifunctional devices. Traditional manufacturing approaches are limited to building planar device configurations. In order to address this limitation, our group has developed a novel hybrid additive manufacturing process that can deposit multi-material patterns on conformal substrates. This direct-write approach involves the combination of microextrusion, pico jet and laser … …American Journal of Engineering and Applied Sciences, Vol. 10, Issue 1 · 20 Mar 2017 · 8,154 accessesView PDF Cite

Research ArticleOpen accessIn the abstractChemical Compositions and Resistant Starch Content in Starchy FoodsAnuchita MoongngarmResistant Starch (RS) is one of nature’s most interesting bioactive compounds. There is a wide variety of starchy food plants in Thailand that are good sources of RS, but they have not been well studied. As such, this study was carried out to investigate the potential food source of RS. Twenty-two promising food plants were selected. The samples included (1) … …American Journal of Agricultural and Biological Sciences, Vol. 8, Issue 2 · 28 Mar 2013 · 15,775 accessesView PDF Cite

Research ArticleOpen accessIn the abstractSynthesis of Zeolite from Aluminium Etching By-Product: the Effect of Reaction Temperature on Crystallinity and Its CO2 Adsorption PropertyKanokorn Hussaro, Supaporn Douglas, Noppadon CheamsawatThe synthesis of zeolite from the by-product of aluminium etching process was investigated. The starting by-product reactant had high aluminium content, 92.17% wt. as Al2O3. Si and Na compositions were adjusted by the addition of sodium metasilicate, in the hydrogel process.The reaction time was fixed at 1 h., while the stirring speed was controlled at 200 rpm. and the temperature … …American Journal of Environmental Sciences, Vol. 4, Issue 6 · 31 Dec 2008 · 6,524 accessesView PDF Cite
