Designed porous milli-scale reactors with enhanced mass transfer performance and reduced pressure drop compared to conventional packed bed reactors.

Milli‐scale reactors with an integrated microstructure offer a promising scale‐up approach for conventional microreactors. This study applies 3D‐printed structured porous millireactors to industrially relevant liquid‐liquid reactions. The underlying transport mechanisms are identified by quantifying interfacial heat and mass transfer. The structured reactors perform limited in Taylor flow compared to a packed‐bed reactor due to limited interfacial mass transfer. However, in stratified flow, their productivity increases significantly at a fraction of the pressure drop of a packed bed.

Controlling the pore architecture in macroporous scaffolds has important implications for their use as reactor packings and as catalyst supports.

Distributed Denial-of-Service (DDoS) assaults are the terrorizing preliminaries on the Internet that exhaust the organization transmission capacity. Analysts have presented different safeguard components including assault counteraction, traceback, response, identification, and portrayal against DDoS assaults, however the quantity of these assaults builds consistently, and the ideal answers for this issue have escaped us up to this point. An order of identification approaches against DDoS assaults is given the point of giving profound understanding into the DDoS problem. Although the anticipation of Distributed Denial of Service (DDoS) assaults is preposterous, location of such goes after assumes principal part in forestalling their advancement. In the flooding assaults, particularly new modern DDoS, the assailant floods the organization traffic toward the objective PC by sending pseudo-ordinary parcels. Hence, multi-reason IDSs don't offer a decent execution (and precision) in distinguishing such sorts of assaults.
