This study is to investigate the capability of producing lignin-based phenol-formaldehyde adhesive (LBPFA) with lignin derived from coir pith collected in Mekong Delta, Viet Nam. The LBPFA synthetic process underwent non chemical modifications minimize petrochemicals and energy. Effective factors as reaction time, temperature various contents phenol substitution were examined. Physical, thermal...

Abstract Plastics are polymers synthesized from petrochemicals or biomass raw materials. In recent decades, worldwide plastics production has increased exponentially. An estimated 8.3 billion tons of plastic have been produced resulting in an 6.3 waste disposed landfill discarded into the natural environment. Plastic is widely used: inexpensive, durable, resource efficient and easily attainable...

Accurately determining phase fractions in two-phase flows is among the most significant issues Industries related to production and processing of petroleum petrochemicals. There are numerous sensor types configurations for measuring void fraction. In this respect, capacitance-based commonly recognized as one precise widely utilized sensors. essay, COMSOL Multiphysics software, which has been be...

Surface-enhanced Raman scattering (SERS) is a label-free and accurate analytical technique for the detection of broad range various analytes such as, biomolecules, pesticides, petrochemicals, as well cellular other biological systems. A key component SERS analysis substrate which required to be equipped with plasmonic features metal nanostructures that directly interact light targeted analytes....
