"Big Bend National Park: Mexico, the United States, and a Borderland Ecosystem" by Michael Welsh is a historical exploration of Big Bend National Park, situated on the border between Mexico and the United States. The book examines the unique landscape of the park, shaped by the Rio Grande river, and the challenges posed by its borderland ecosystem. Welsh discusses the efforts of conservationists, politicians, and scientists in establishing the park and highlights the potential for binational cooperation and collaboration. The book also addresses the tensions between preservation and development in national parks and the need to navigate the changing cultural and political landscape. While the book lacks an examination of the park's future in the face of climate change and public policy, it offers valuable insights for students and scholars interested in national identity, border relations, and environmental protectionism.

We developed a disposable paper battery aiming to reduce the environmental impact of single-use electronics for applications such as point of care diagnosis, smart packaging and environmental sensing. The battery uses Zinc as a biodegradable metal anode, graphite as a nontoxic cathode material and paper as a biodegradable substrate. To facilitate additive manufacturing, we developed electrodes and current collector inks that can be stencil printed on paper to create water-activated batteries of arbitrary shape and size. The battery remains inactive until water is provided and absorbed by the paper substrate, taking advantage of its natural wicking behavior. Once activated, a single cell provides an open circuit potential of 1.2 V and a peak power density of 150 µW/cm2 at 0.5 mA. As a proof of concept, we fabricated a two cell battery and used it to power an alarm clock and its liquid crystal display. [ABSTRACT FROM AUTHOR]
