3D printing technology has an enormous potential to apply to chemical engineering education. In this paper, we describe several designs of 3D printed mesoreactors (Y-shape, T-shape, and Long channel shape) using the following steps: reactor sketching, CAD modeling, and reactor printing. With a focus on continuous plug flow mesoreactors (PFRs, i.d. = 2 mm), fluid mixing phenomena were explored by using a passive mixing method. The small channel of mesoreactors facilitates the stability of a laminar flow in the system at low Reynolds number. With changes in flow rates (0.2 and 4.0 mL/min) and channel geometry (0° and 90° outlet angle), fluid mixing was controlled. Our results provided that 3D printed mesoreactors can be possibly used in teaching fluid dynamics, chemical kinetics, and reaction engineering, which are main courses of the chemical engineering undergraduate program. Furthermore, the cost of mesoreactor printing was suitable (<$1.00/microreactor) for education.

The goal of the MedizDroid Project is to research the affordable and sustainable use of aerial platforms (UAV, UAS, MAVs, drones, multi-copters and multi-rotors), briefly malaria mosquito control drones, for mosquito vector control and suppression. Mosquitoes are vectors for several diseases including malaria, Chikungunya, dengue fever, lymphatic filariasis (elephantiasis), West Nile virus disease, and yellow fever. Therefore, for each infectious disease, a very important aspect of integrated disease management is vector control. Current methods of mosquito control include using: a)Screens; b) Repellents; c) Insecticide treated bed nets (LLINs, ITNs, INs); d) Indoor residual spraying (IRS); e) Outdoor residual spraying (ORS): treatment of resting sites; f) Larval source management (LSM):treatment of breeding sites and water bodies; larviciding (LC); using biological controls (BC); g) Ultra-Low Volume (ULV) space spraying: aerial spraying; ground vehicle mounted spraying; h) External environment & habitat management, modification and manipulation (EHM*). The focus of the Project is the automation of IRS, ORS, LSM (and later EHM*), in developing affordable and sustainable drone-based systems that can be deployed in malaria endemic sub-Saharan Africa and elsewhere. The current most realistic method of backpack spraying has many challenging issues.Currently the Project is at the stage of specifying, simulating and prototyping subsystems: heavy lift and long endurance UAVs using hybrid power; composite and parasite drones; electronically controllable vector control payloads; and structured software platforms and architectures.Keywords-uav, multicopter, drone, mosquito control, malaria, integrated vector management, larval source management, indoor residual spraying, outdoor residual spraying, autopilot.I.

The ongoing KOM Project is researching how to construct affordable and sustainable mosquito-free zones, in malaria endemic sub-Saharan Africa and elsewhere. Mosquitoes are vectors for several diseases malaria, Chikungunya, dengue fever, lymphatic filariasis (elephantiasis), Ross River fever, West Nile virus disease and yellow fever. Isolating mosquitoes from hosts also breaks disease transmission. In summary, KOMKOM: Keep Out Mosquitoes = Keep Out Malaria KIMKIM: Keep In Mosquitoes = Keep In Malaria So, one wants to re-engineer habitations as bio-zones on the landscape scale [ O(1) mile ]: Mosquito-free zones (MFZ), KOM enclosures; Mosquito-confinement-containment zones (MCZ), KIM enclaves.A KOM (KIM) enclosure is a mosquito-impenetrable wall surrounding an area, deployed permanently or seasonally in a rural or urban setting. The barrier is augmented with a distribution of BTK (bait-trap-kill) units. Mosquitoes can then be subjected to herding, destruction or entomological assessments. Currently, the Project is in the concept development stage, and is specifying and prototyping subsystems: KOM (KIM) walls, fringes: skirts and collars; BTK units; airlock technology for entry-exit ways; and automating vector destruction. The companion MedizDroids Project is researching UAVs, drones and multi-copters as mosquito control drones for vector control, that can exploited to eliminate mosquitoes from KOM (KIM) zones.
