Making graphene visible
Microfabrication of graphene devices used in many experimental studies currently relies on the fact that graphene crystallites can be visualized using optical microscopy if prepared on top of Si wafers with a certain thickness of SiO2. We study graphene’s visibility and show that it depends strongly on both thickness of SiO2 and light wavelength. We have found that by using monochromatic illumi...
متن کاملMaking the invisible visible.
There would be no population problems if people were not concerned about the evidently increasing difficulties of survival. Such is not the case as is evident in the global efforts for economic and social development. Yet, in the minds of most people the population question as a "situation" or a "problem" does not exist. When its reality is asserted by others, it is frequently regarded as a ...
متن کاملMaking Thought Visible
Creative thought is invisible. Sketches of thought not only make it visible to others, so they can study creativity, and to self, to foster creativity. Sketches reveal thought, promote communication, and foster inference and discovery. A range of quantitative and qualitative data from coding sketches, interactions with sketches, and inferences from sketches uphold these conclusions. 1. Solving ...
متن کاملBook Review: Making Thinking Visible
Recent trends in medical education emphasize the importance of producing well-rounded graduates who not only possess a sufficient fund of medical knowledge but who can think clearly and deeply. Unfortunately, many medical educators struggle with what exactly it means to “think” and do not know where to begin when asked to teach “thinking.” We believe the book Making Thinking Visible, though wri...
متن کاملMaking Graphene for Macroelectronics
254 nature nanotechnology | VOL 3 | MAY 2008 | www.nature.com/naturenanotechnology The third issue concerned the choice of organisms in the experiment. What are the criteria for choosing the organism and which outcomes should be measured after particle exposure? These choices depend largely on whether one is studying the mechanism of toxicity or performing a riskassessment analysis. In general,...
