Why we should capitalise on early childhood interest in engineering: changes in students’ interest over the school years

Patterning of metals is a key element in the fabrication of integrated microelectronics. For circuit repair and engineering changes constructive lithography, writing techniques, based on electron, ion or photon beam-induced decomposition of precursor molecule and its deposition on top of a structure have gained wide acceptance Recently, scanning probe techniques have been used for line drawing and wire growth of W on a silicon substrate for quantum effect devices. The kinetics of electron beam induced W deposition from WF6 gas has been studied by adsorbing the gas on SiO2 surface and measuring the growth in a TEM for various exposure times. Our environmental cell allows us to control not only electron exposure time but also the gas pressure flow and the temperature. We have studied the growth kinetics of Au Chemical vapor deposition (CVD), in situ, at different temperatures with/without the electron beam on highly clean Si surfaces in an environmental cell fitted inside a TEM column.

This article describes an early intervention program designed for speech-language pathologists enrolled in a master's-level program. The program provided students with courses and clinical experiences that prepared them to work with birth to 5-year-old children and their families in a family-centered, interdisciplinary, and ecologically valid manner. The effectiveness of the program was documented by pre- and post-training measures and supported the feasibility of instituting an early childhood specialization within a traditional graduate program in speech-language pathology.
