Office Chromatography: Miniaturized All-in-One Open-Source System for Planar Chromatography.
Analytical chemistry, 2018Co-Authors: Dimitri Fichou, Gertrud E MorlockAbstract:Current high-performance-thin-layer-chromatography instrumentation is offline and stepwise automated. However, moderate miniaturization offers many advantages and together with the transfer of modern print and media technologies to the field of chromatography (office chromatography) it Opens up new avenues. This is demonstrated in an all-in-one Open-Source System developed for planar chromatography and especially for ultrathin-layer chromatography. Using an InkShield board to control a thermal inkjet cartridge, picoliter drops were printed at a resolution of 96 dpi on the adsorbent layer. Using Marlin, a popular firmware in 3D printing, Cartesian movement of the print head was made possible for full control of the printing process. Open-Source software was developed to control the device in each operation step. Sample solutions and mobile phase were inkjet-printed, exemplarily shown for the analysis of dye- or paraben-mixture solutions. Light-emitting diodes (LEDs) were investigated for documentation. For example, deep UV LEDs gave access to 254 nm light, and RGB LEDs gave access to the visible-light range. Calibration functions with correlation coefficients superior to 0.999 were obtained by videodensitometry. The developed modular Open-Source hardware was compact (26 × 31 × 26 cm3), light (

The developed modular Open-Source hardware was compact (26 × 31 × 26 cm3), light (<3 kg), and affordable (€810). For the given analyses, the footprint of current instrumentation needed was miniaturized by a factor of 9. The highly reduced material design complies with green chemistry and lean laboratory. The design and instruction to reproduce the all-in-one Open-Source System were made freely available at https://github.com/OfficeChromatography . It is intended to boost progress and understanding by the nature of do it yourself.

an Open Source System for vision based micro aerial vehicle mapping planning and flight in cluttered environments
Journal of Field Robotics, 2020Co-Authors: Helen Oleynikova, Christian Lanegger, Zachary Taylor, Michael Pantic, Alexander Millane, Roland Siegwart, Juan NietoAbstract:We present an Open-Source System for Micro-Aerial Vehicle autonomous navigation from vision-based sensing. Our System focuses on dense mapping, safe local planning, and global trajectory generation, especially when using narrow field of view sensors in very cluttered environments. In addition, details about other necessary parts of the System and special considerations for applications in real-world scenarios are presented. We focus our experiments on evaluating global planning, path smoothing, and local planning methods on real maps made on MAVs in realistic search and rescue and industrial inspection scenarios. We also perform thousands of simulations in cluttered synthetic environments, and finally validate the complete System in real-world experiments.

Smart Route Planning Using Open Data and Participatory Sensing
2015Co-Authors: Vivek Nallur, Amal Elgammal, Siobhán ClarkeAbstract:Smart cities are not merely the infusion of technology into a city’s infrastructure, but also require citizens interacting with their urban environment in a smart and informed manner. Transportation is key aspect of smart cities. In this paper, we present a smart route planning Open-Source System; SMART-GH utilizes Open data and participatory sensing, where citizens actively participate in collecting data about the city in their daily environment, e.g., noise, air pollution, etc. SMART-GH then augments the routing logic with sensor data to answer queries such as ‘return the least noisy route’. SMART-GH enables citizens to make smarter decisions about their daily commute, and subsequently improve their quality of life.
