Additively Manufactured Parametric Universal Clip-System: An Open Source Approach for Aiding Personal Exposure Measurement in the Breathing Zone + (Design for additive manufacturing is adopt … Design for additive manufacturing is adopted to help solve problems inherent to attaching active personal sampler systems to workers for monitoring their breathing zone. A novel and parametric 3D printable clip system was designed with an open source Computer-aided design (CAD) system and was additively manufactured. The concept was first tested with a simple clip design, and when it was found to be functional, the ability of the innovative and open source design to be extended to other applications was demonstrated by designing another tooling system. The clip system was tested for mechanical stress test to establish a minimum lifetime of 5000 openings, a cleaning test, and a supply chain test. The designs were also tested three times in field conditions. The design cost and functionalities of the clip system were compared to commercial systems. This study presents an innovative custom-designed clip system that can aid in attaching different tools for personal exposure measurement to a worker's harness without hindering the operation of the worker. The customizable clip system opens new possibilities for occupational health professionals since the basic design can be altered to hold different kinds of samplers and tools.

Open source nanotechnology + (Despite being an extremely active area for … Despite being an extremely active area for academic research, publishing and patent applications, nanotechnology development is being hindered by current intellectual property (IP) law. Patenting of basic science and entire classes of nanotechnologies is leading to higher transaction costs, slower technical development and the removal of obvious knowledge from the public domain. This effectively hamstrings the current primal nanotechnology development, in contrast to the history of other emerging technical fields (e.g. software).emerging technical fields (e.g. software).)

In contrast to other emerging fields at their times, nanotechnology was born as the Bayh–Dole Act enabled universities to lock down fundamental research effectively preventing open competition. Both technical complexity and bureaucratic mishandling of nanotechnology patent applications have created a dense patent thicket of overlapping claims and rights. This intellectual property tragedy restricts downstream innovation by preventing development of more complex technologies due to exorbitant transaction costs. This article addresses this tragedy with the application of the free and open-source paradigm from software development as open-source methodologies will both accelerate nanotechnology innovation and improve the social return from public investment in nanotechnology research.lic investment in nanotechnology research.)
Optimal inverter and wire selection for solar photovoltaic fencing applications + (Despite the benefits and the economic adva … Despite the benefits and the economic advantages of agrivoltaics, capital costs limit deployment velocity. One recent potential solution to this challenge is to radically reduce the cost of racking materials by using existing farm fencing as vertical photovoltaic (PV) racking. This type of fenced-based PV system is inherently electrically challenging because of the relatively long distances between individual modules that are not present in more densely packed conventional solar PV farms. This study provides practical insights for inverter selection and wire sizing optimization for fence-based agrivoltaic systems. Numerical simulation sensitivities on the levelized cost of electricity (LCOE) were performed for 1) distance from the fence to the AC electrical panel, 2) inverter costs, and 3) geographic locations. The results showed that microinverters had better performance when the cross-over fence length was under 30 m or when the system was designed with less than seven solar PV modules, whereas string inverters were a better selection for longer fences. The cross-over number of modules depends significantly on the cost of the inverters, which is a parameter that influences the system's design. The capital costs for a fence retrofit are far less than for any form of conventional PV racking. In addition, the LCOE of the vertical fencing solar agrivoltaic system can be competitive with conventional ground-mounted solar PV for the niche of farmers. Especially, when they are located between the latitudes of 10° and 50° in either the northern or southern hemisphere, and coupled with their ancillary benefits they represent a great alternative for conventional PV systems.t alternative for conventional PV systems.)
Decarbonizing the boardroom? Aligning electric utility executive compensation with climate change incentives + (Despite the drastic reversal of decarboniz … Despite the drastic reversal of decarbonization effort by the Trump administration, the majority of U.S. states continue policies aimed at reducing greenhouse gas (GHG) emissions and increasing renewable energy technology (RET) deployment. Although electrical power utilities are required and/or encouraged to comply with these policies, their executives lack direct incentives to do so. In this study, a novel incentive mechanism is evaluated for aligning utility executive compensation with such policies. First, an overview is provided on chief executive officer (CEO) pay and the GHG emissions of utilities. The relationship between GHG emissions, renewable energy diversification, and CEO pay is examined using the case study of three of the largest electric utilities in Michigan. The results show that the regulated utility market is not consistently rewarding CEOs with higher compensation for decreasing GHG emissions and that both an approach incentivizing RETs adoption and an approach encouraging GHG emissions have deficiencies. A combined approach is then analyzed that results in a compensation equation allowing for utility executives to receive incentive pay for reducing overall emissions and increasing renewable generation. The results indicate that by careful calibration of the proposed incentive equations the harmful effects of emissions can be prevented through CEO incentive pay.an be prevented through CEO incentive pay.)
