The concept of“carbon neutrality”poses a huge challenge for chemical engineering and brings great opportunities for boosting the development of novel technologies to realize carbon offsetting and reduce carbon emissions.Developing high-efficient,low-cost,energy-efficient and eco-friendly microfluidicbased microchemical engineering is of great significance.Such kind of“green microfluidics”can reduce carbon emissions from the source of raw materials and facilitate controllable and intensified microchemical engineering processes,which represents the new power for the transformation and upgrading of chemical engineering industry.Here,a brief review of green microfluidics for achieving carbon neutral microchemical engineering is presented,with specific discussions about the characteristics and feasibility of applying green microfluidics in realizing carbon neutrality.Development of green microfluidic systems are categorized and reviewed,including the construction of microfluidic devices by bio-based substrate materials and by low carbon fabrication methods,and the use of more biocompatible and nondestructive fluidic systems such as aqueous two-phase systems(ATPSs).Moreover,low carbon applications benefit from green microfluidics are summarized,ranging from separation and purification of biomolecules,high-throughput screening of chemicals and drugs,rapid and cost-effective detections,to synthesis of fine chemicals and novel materials.Finally,challenges and perspectives for further advancing green microfluidics in microchemical engineering for carbon neutrality are proposed and discussed. 展开更多

Microfluidic systems provide a powerful platform for preparing,functionalizing,and manipulating nano-/micro-materials.In this review,we summarize the characteristics of state-of-the-art microfluidic techniques and their application to processing novel nano-/micro-materials with tunable size,shape,morphology,composition,and properties.A variety of synthesis strategies based on novel microfiuidic devices are presented and compared,including their integration with real-time monitoring,external fields,and automatic feedback control.Novel functional nano-/micro-materials with complex structures have been controllably prepared and post-processed to obtain high-quality products.Strategies for controlling and tuning physical and chemical properties are also examined in terms of the design and function of microfluidic platforms.We provide an outlook on future developments in the processing of nano-/micro-materials by microfluidic technologies. 展开更多
