Summary: Expanding the variety of high-temperature/high-performance polymer 3D printing feedstocks is crucial for wider adoption in aerospace applications. Open-source printers provide a potential platform for introducing new materials, but they are not capable of printing high-temperature polymers by default. To address this issue, we developed an open-source-based 3D printer with enhanced environment controls that enable printing of high-temperature polymers without damaging the machine.

Summary: 3D printing technology has been widely used to produce cost-effective and high-precision parts. Recent studies have demonstrated its potential in fabricating magic-angle spinning (MAS) systems in solid-state nuclear magnetic resonance (NMR) spectroscopy. In this study, it is shown that affordable benchtop 3D printers can produce MAS drive caps with similar quality to commercial versions, and even smaller caps with slight compromise in performance. The low-cost and fast in-house fabrication of MAS drive caps enables easy prototyping of new models and opens up possibilities for new NMR applications.

Summary: This study aims to assess the environmental impact of using an imine-based covalent organic framework (RT-COF-1) for surface printing (Case A) and 3D inkjet printing (Case B) through life cycle assessment (LCA) methodology. The results show that monomer synthesis is the main contributor to environmental impacts in both cases, and solvents used in Case A also have a significant contribution. Case B has lower environmental impacts compared to Case A. Furthermore, RT-COF-1 compares favorably with polymerizable ionic liquids (PILs) in terms of environmental performance for 3D printing.

Utilizing waste heat from cryptocurrency mining can reduce greenhouse heating costs. A thermal model was developed to estimate the heating and cooling demands of greenhouses, and experimental evaluation showed the potential of cryptocurrency mining for heating. Parametric analysis demonstrated the economic profitability of using waste heat depending on utility rates and Bitcoin value.

Summary: This study investigates the retrofitting of existing animal fencing on farms for vertical-mounted photovoltaic (PV) racking, in order to reduce the capital cost of agrivoltaic systems. Different types of fences and wind load calculations are analyzed to determine the feasibility of fence-based PV racking across the U.S. The results show that retrofitting PV modules on existing fencing can save costs and lower the levelized cost of electricity, but further research is needed to assess the full benefits of vertical PV agricultural fencing on a global scale.

Summary: Canada aims to reduce greenhouse gas emissions and increase the non-emitting share of electricity generation to 90% by 2030. This study shows that agrivoltaics, the combination of solar photovoltaic systems and agriculture, have the potential to provide a significant portion of Canada's electricity needs. By using a small percentage of agricultural lands, agrivoltaic systems can potentially supply between a quarter and more than one third of Canada's electricity demand. This presents an opportunity for sustainable electricity generation, electrification of transportation and heating, economic growth in the computing sector, and help eliminate fossil fuel dependence in the US through green electricity exports.

Summary: Although open source DAQ systems have been published, closed source proprietary systems are still widely used despite their high costs. However, the high costs limit access to high-quality DAQ in low-resource settings. While the global library of open source electronic designs is expanding rapidly, current open source devices often lack the ability to scale up or easily integrate with other designs. This article introduces and tests a new framework, the Broadly Reconfigurable and Expandable Automation Device (BREAD), which allows for the development of new open source electronics with plug-and-play functionality.

Summary: Despite the Canadian federal government's $3.1 billion investment in health information technology (HIT), each of the 10 provinces still maintains separate HIT systems that are costly, inconsistent, and lack interoperability. This paper proposes the use of HermesAPI, a free and open-source software, to integrate the common functions of billing, lab results, and diagnostic imaging across these systems. The study found that implementing HermesAPI would save a total of CAD$6.4 million by reducing development costs for private EMR companies, while also promoting competition and improving patient care.
