Energy sources will contribute enormously to global economic development in the coming years. Global energy sectors mainly depend on fossil fuels, which greenhouse gas emissions. With threat of declining oil supplies and need reduce CO2 emissions, viable substitutes for fuels is high priority list. Currently, there an increased focus using low alcohols as petrochemicals. Catalytic conversion a ...
Polyhydroxyalkanoates (PHAs) have become important due to their mechanical properties, which resemble those of plastics derived from petrochemicals. Despite the advantages they possess, its use is limited by production costs. In terms culture systems used for process improvement, fed batch are most studied, since allow higher productivity be obtained. this study, PHAs was reviewed with a new fe...
The front cover picture illustrates whole cells-based cascade reactions to produce (R)- and (S)-2-phenylglycinols from simple chemicals. Artificial enzyme cascades were developed for the one-pot green syntheses of bio-based L-phenylalanine. Natural L-phenylalanine biosynthesis pathway was coupled with artificial directly convert renewable feedstocks such as glucose glycerol (S)-2-phenylglycinol...
Material mechanical behavior is critical for both safety and economic considerations. Because engineering items are manufactured using appropriate grade materials, approval of the materials used must be completed before assembly. Petrochemicals, marine, biomaterials just a few industries that use stainless steel. Despite its extensive use, structural failure still frequently caused by inadequat...
Biomass is an abundant and environmentally friendly source for materials that can be used in a multitude of applications the effort to replace petrochemicals. Furfural malonic acid are biomass-sourced platforms utilized synthesis biobased compounds; rctt-3,4-di-2-furanyl-1,2-cyclobutanedicarboxylic (CBDA-2) one such compound. In this study, CBDA-2 has been introduced into metal-organic chemistr...
The interest in the low energy self-emulsification techniques has exploded recent years, driven by three main trends: transition to "greener" technologies both its aspects - less consumption and replacement of petrochemicals natural ingredients; costly maintenance demanding equipment for nanoemulsification; quest efficient robust self-emulsifying formulations oral drug delivery. Here we first p...
Heavy industries such as cement, iron and steel, oil refining, petrochemicals are responsible for about 22% of global carbon dioxide (CO2) emissions. There exist several pathways CO2 mitigation. Capturing, storage, utilization (CCS CCU) provide an operational solution significant emission High purity streams the most interesting points CCS CCU. Pure suitable compression, transport, storage. Cap...
