Recovery processes of sustainable energy using different biomass and wastes

Abstract: The biomass ‘waste-to-energy theory transforms low-value biomass within value-added outputs which include high financial potential has drawn awareness from both academicians and enterprise professionals. The biomass waste administration method involves the production, chamber, acquisition, transferal, and conveyor, processing, and distribution of all classes of trash. However, most of these methods are yet under the growing state and attempting to acquire a business partly due to several hurdles, such as proper infrastructure, feedstock, technological conditions, administration management, and communal recognition. Recently, thermochemical methods towards agricultural biomass to power conversion appear encouraging and achievable. The comparative benefit of thermochemical transformation above others is higher potency and adaptability among subsisting infrastructure tools. These advantages differ by method and final product, presenting compliance in matching market necessities. Advantages include environmental change: upon a life-cycle base, high-level biofuels generated through thermochemical transformation could decrease greenhouse gases by around 50% or higher than traditional gasoline. In this article, a comprehensive report on the advancement of the five most encouraging ways of thermochemical transformation (i.e. incineration, pyrolysis, gasification, plasma, and torrefaction), three ways of biochemical renovation (i.e. composting, bioethanol fermentation and anaerobic digestion) and landfill methane capture have been discussed. The modern evolution of several conversion technologies for biomass regeneration has also been examined and benchmarked towards global development. Additionally, the core scientific hurdles in profiting these green pieces of machinery are emphasized.

On water: silver-catalyzed domino approach for the synthesis of benzoxazine/oxazine-fused isoquinolines and naphthyridines from o-alkynyl aldehydes.

Abstract: An operationally simple domino approach for the silver-catalyzed synthesis of oxazine/benzoxazine-fused isoquinolines 5a–q and naphthyridines 6a–v by the reaction of o-alkynyl aldehydes 3a–aa with amines having embedded nucleophiles 4a–d under mild reaction condition in water is described. The reaction shows selective C–N bond formation on the more electrophilic alkynyl carbon resulting in the formation of 6-endo-dig cyclized product. The competitive experiments show the viability of an intramolecular nucleophilic attack over an intermolecular attack of the external nucleophile. This methodology accommodates wide functional group variation, which proves to be useful for structural and biological assessment.
