Fabrication of flexible thermoelectric generators

One disadvantage to using conventual thermoelectric generators (TEGs) to harvest heat waste is that they are inefficient where the heat source has a curved surface or has moving parts. Herein the fabrication of a flexible thermoelectric generator (FTEG) is discussed as a solution to harvest energy from these scenarios. Solution phase printing of nanomaterials is becoming an increasing appealing method in the creation of flexible energy harvesting devices. Inkjet printing of n-type bismuth telluride (Bi2Te3) and bismuth antimony telluride (Bi0.5Sb1.5Te3) nanowires (NWs) onto polyimide that is then annealed, interconnected by eutectic gallium indium (EGaIn) liquid metal and coated in silicone elastomer results as a FTEG. The device delivered a maximum power density of 11.78 mWïÿýcm-3 at a 15 K temperature difference. Also, the performance of the FTEG did not diminish after multiple bends and wraps (up to 100) around a tight radius of curvature (rod – dia. 7.5 mm). Hence this inkjet printed FTEG is a step forward towards a wearable energy harvesting device. This report is based on the recently submitted manuscript “Flexible, Inkjet-Printed Thermoelectric Generators with Inkjet-Printed Bismuth Telluride Nanowires and Liquid Metal Contacts”

California\u27s Statutory Attempt to Regulate Foreign Corporations: Will It Survive the Commerce Clause

Section 2115 of the California Corporations Code asserts control over select internal affairs of a foreign corporation if the corporation satisfies the two tests outlined in the statute. Examples of internal affairs include the election and removal of directors, method of voting for directors, and reorganizations and mergers. This Comment examines section 2115 in relation to the commerce clause of the United States Constitution. California\u27s interests in enforcing the statute are balanced against the burdens imposed upon the free flow of interstate commerce. The author concludes that application of section 2115 excessively burdens interstate commerce and is therefore unconstitutional

Market Forces and Price Ceilings: A Classroom Experiment

The effect of price controls on competitive equilibrium is a standard topic in many undergraduate economics courses. This classroom experiment demonstrates the effect of rent control (price ceilings) on the market for apartments. As participants in the experiment, students experience the effect of a price ceiling as buyers (renters) and sellers (landlords). The classroom-posted offer market exhibits a shortage under a binding price ceiling. Further, we explore a secondary response to rent control. When given the opportunity, landlords lower the quality of the apartments by reducing maintenance expenditures under the price ceiling, thus moving the market back to equilibrium. Since many students are themselves renters, they should relate to changes in quality due to lower maintenance by landlords. This experiment will stimulate discussion on market forces and on public policy aimed at restricting prices.

A History Of The Improvement Of Internet Protocols Over Satellites Using ACTS

This paper outlines the main results of a number of ACTS experiments on the efficacy of using standard Internet protocols over long-delay satellite channels. These experiments have been jointly conducted by NASA’s Glenn Research Center and Ohio University over the last six years. The focus of our investigations has been the impact of long-delay networks with non-zero bit-error rates on the performance of the suite of Internet protocols. In particular, we have focused on the most widely used transport protocol, the Transmission Control Protocol (TCP), as well as several application layer protocols. This paper presents our main results, as well as references to more verbose discussions of our experiments.
