Continuous-mode SandX Rector Automation


Project Description

SandX is a nature-inspired super-water-repellent material comprised of common sand grains coated with paraffin wax in a 1:1000 mass ratio. When applied as a 1 cm-thick layer on the topsoil, SandX can dramatically reduce (~80%) the evaporative loss of water and increase biomass growth and crop yields by up to 70%. SandX’s efficacy to boost crop yields has been established via multi-year field trials on barley, wheat, tomato, green pepper, onions, and okra (Please refer to After about 9 months of its application, SandX degrades into Sand and becomes a part of the soil. We have conducted soil microbiome analysis and found that it has no adverse impact on soil microbial diversity. Currently, we are automating our pilot-scale continuous reactor for manufacturing SandX, which we are seeking an intern for assistance. The ideal candidate will have hands-on experience in automation, reactor engineering, control systems, sensors, software, data logging, etc.
