<p><em>Elementary children are at an age of investigation and exploration. In today’s society, this exploration often occurs using technology. Whether learning to type with Typing Club, using Google to search for information on Yellowstone National Park or designing and creating a city in Minecraft, technology has become a part of every child’s existence. Early access to technology could be the impetus to a students’ pursuit of a degree in STEM disciplines. Presented here is a conglomerate of University, Community College and High School sites that provide free access to advanced scientific technologies remotely for students to view and manipulate for themselves. The Remotely Accessible Instruments in Nanotechnology (RAIN) Network provides Scanning Electron (SEM), Atomic Force (AFM) and Confocal Microscopes to educators and allows an opportunity to connect with higher education scientist across the globe, with the goal of using technology to enhance the teaching of science to our children.</em><em></em></p>

Horticulture Teaching Resources is a web site at The Ohio State Univ. designed to provide high school and higher education horticulture educators free-access to curriculum resource materials. The information has been structured to facilitate the instruction of basic concepts in plant biology, propagation, nutrition, and plant materials. A searchable database interface is used to access color photos, lab exercises, and test questions. Users of the system can also provide URL addresses to their own resources for inclusion in the database. (http://hortwww-2.ag.ohio-state.edu/hvp/htr/htr.html)

AbstractThis project was initiated with an undergraduate student’s exploration of two advanced research tools: the scanning electron microscope (SEM) and the atomic force microscope(AFM). A research project was developed to study the application of microscopy to introductory physics instruction. Nine modules covering various aspects of introductory physics were created. Module components included discussions, laboratory experiments and assessments. Four of the nine modules were implemented in various high school classes. Assessments were used to compare student learning with the modules versus standard textbook/lecture techniques. Preliminary results of this study are presented along with recently developed methods created to facilitate implementation of these modules within the high school classroom.

Russian Education

The dynamics of several demographic indicators of Russia - child and teenage cohorts in 1970-2000, life expectancy in 1995-2000, migration flows among federal districts in the period between two censuses of 1989 and 2002 - are considered in the article. The author puts forward the hypothesis about the influence of these indicators on the level of education in narrow and broad senses - in educational institutions and the society as a whole. He estimates the perspectives of regional higher educational institutions under conditions of absence of plan distribution of graduates and the double cyclical fall in the number of high school graduates. The agenda for the development of a two-stage system of higher education corresponding with international integration processes is formulated.

This study examined and compared surface of human dentine after acidic etching with hydrogen peroxide, phosphoric acid liquid and gel. Surface demineralization of dentin is necessary for a strong bond of adhesive at dental surface. Split human teeth were used. After application of mentioned substances at dentin level measures of the contact angle and surface morphology were employed. Surface morphology was analyzed with the help of scanning electron microscopy and atomic force microscopy. Liquid phosphoric acid yielded highest demineralization showing better hydrophobicity than the rest, thus having more contact surface. Surface roughness are less evident and formed surface micropores of 4 �m remained open after wash and air dry providing better adhesive canalicular penetration and subsequent bond.

In this work, a mechanically durable anticorrosion superhydrophobic coating is developed using a nanocomposite coating solution composed of silica nanoparticles and epoxy resin. The nanocomposite coating developed was tested for its superhydrophobic behavior using goniometry; surface morphology using scanning electron microscopy and atomic force microscopy; elemental composition using energy dispersive X-ray spectroscopy; corrosion resistance using atomic force microscopy; and potentiodynamic polarization measurements. The nanocomposite coating possesses hierarchical micro/nanostructures, according to the scanning electron microscopy images, and the presence of such structures was further confirmed by the atomic force microscopy images. The developed nanocomposite coating was found to be highly superhydrophobic as well as corrosion resistant, according to the results from static contact angle measurement and potentiodynamic polarization measurement, respectively. The abrasion resistance and mechanical durability of the nanocomposite coating were studied by abrasion tests, and the mechanical properties such as reduced modulus and Berkovich hardness were evaluated with the aid of nanoindentation tests.
