Informal Science Education and Career Advancement

This document supports a proposed APS statement that encourages academic, research, and other institutions to add the participation in informal science education activities to the criteria they use for hiring and career advancement decisions. There is a prevalent attitude that the time spent by a researcher on these activities takes time away from research efforts that are more valued by their peers and their institution. To change this mindset, we enumerate the many benefits of informal science education activities to the public, to researchers, to their institutions, and to the field of physics. We also suggest aspects of these activities that may be considered by institutions in evaluating informal educational efforts for recruitment and career advancement decisions.

Plasma Generation by Household Microwave Oven for Surface Modification and Other Emerging Applications

In this paper we describe a simple and inexpensive method to generate plasma using a kitchen microwave. The microwave-generated plasma is characterized by spectroscopic analysis and compared with the absorption spectra of a gas discharge tube. A Paschen-like curve is observed leading to a hypothesis of the microwave plasma generation mechanism in air. We have also demonstrated that this microwave generated air plasma can be used in a multitude of applications such as: a) surface modification of a substrate to change its wettability; b) surface modification to change electrical/optical properties of a substrate; and c) enhancement of adhesive forces for improved bonding of polymeric microfluidic molds, such as bonding polydimethylsiloxane (PDMS) chips to glass covers. These simple techniques of plasma generation and subsequent surface treatment and modification may lead to new opportunities to conduct research not only in advanced labs, but also in undergraduate and even high school research labs.
