The study offers a promising approach to reducing the >870,000 deaths/year globally from unsafe water through the use of flow-through solar water pasteurization systems (SWPs). The high cost of the heat exchanger (HX) is addressed with the introduction of of a polymer microchannel HX as a substitute for coiled copper. The polymer microchannel HX is designed for a 3-D printed collector. The paper focuses on SWP systems fabricated using fully open-source distributed manufacturing.

Graduate student Adam Pringle (MSE) has been named one of nine finalists worldwide for a project he submitted to the international “Make A Difference” competition. As a finalist, he will be flown to Hamburg, Germany, to present his project at OpenLab Hamburg in November 2017.

The project, “Composite Filament Fabrication Process,” focuses on ecological sustainability by breaking down waste materials and turning them into composite 3-D printing filament, which then can be used to make useful products.

The “Make A Difference” competition seeks ideas that provide solutions for the needs of refugees, the health of society, education and ecological sustainability.

Finalists will build, test and showcase prototypes of their projects at OpenLab Hamburg, and one overall winner will be selected.

Pringle is a member of Joshua Pearce’s (MSE) research group, Michigan Tech Open Sustainable Technology (MOST) lab.

Original story by Jenn Donovan.

“Make a Difference” is an idea challenge for everyone. It aims toward making a social and ecological impact based on the open source principles. For the 2017 Idea Challenge, 76 ideas were received, the top 20 ideas were considered for the final evaluation, and nine finalists are going to Hamburg. Professor Joshua Pearce is among the jurists.

OpenLab Hamburg takes place October 30 to November 3. Digital, high-end devices will be at the service of the finalists, who will work with the OpenLab team to make their dreams come true. “Make a Difference”  is the inaugural Idea Challenge organized by the Helmut Schmidt University, Hamburg, and the Arab German Young Academy.


Jaroslaw Drelich Leads the Acquisition of an Atomic Force Microscope

Jaroslaw Drelich (MSE) is the principal investigator on a project that has recevied a $135,669 research and development grant from the National Science Foundation (NSF).

Shiyue Fang (Chem), Tarun Dam (Chem), Xiaohu Xia (Chem) and Kathryn Perrine (Chem) are the Co-PIs on the project, “MRI: Acquisition of an Atomic Force Microscope for Force Measurement, Single-Molecule Manipulation and other Applications.” This is a three-year project.

Abstract

This award is supported by the Major Research Instrumentation (MRI) and the Chemistry Instrumentation and Facilities (CRIF) programs. Professor Jaroslaw Drelich from Michigan Technological University and colleagues are acquiring an atomic force microscope (AFM). An AFM is a powerful tool to look at single molecules on a surface. It operates through an atomically sharp tip attached to an extremely soft cantilever that can sense forces at tiny atomic levels (pico-newton forces). Utilizing the forces between tip and a molecule, AFM can even be used to manipulate single molecules moving them to desired locations. Using this information, projects measure the mechanical strength of single covalent bonds. This can lead to practical applications, for example, preparing better quick-response and moisture-resistant smart adhesives. Adhesion forces between materials for civil engineering application can be investigated. The research enabled by the AFM will have broad impacts in areas such as health, energy, environment and national security, and even the economy. Faculty, postdoctoral researchers, graduate students, and undergraduate researchers in at least 16 research groups at Michigan Tech are trained to use this powerful instrument.

This atomic force microscope enhances research and education in areas by measuring van der Waals and magnetic forces between the tip and surface; the rupture force of non-covalent interactions between molecules and tip, and the scission force of covalent bonds in a molecule anchored between the tip and surface. Applications to projects include monitoring enzyme catalysis in real-time, and performing surface charge microscopy of biological cells. The microscope is used in the study of quick-response and moisture-resistant smart adhesives, and adhesion forces between materials for civil engineering applications. In other projects the shape and surface characteristics of atmospheric particles and atmospheric processing of black carbon are studied. The lattice structures of proteoglycan-galectin-3 cross-linked complexes are imaged and the ligand binding force of galectin-3 is measured.
