Porous silicon manufactured in a bottom up procedure using solar energy can be used to generate hydrogen from water, according to a team of Penn State mechanical engineers, who also see applications for batteries, biosensors and optical electronics as outlets for this new material.
ASU undergraduates have the opportunity to enroll in a challenging course this fall, designed to re-introduce the act of play as a problem-solving technique. The course is offered as part of the larger project, Cross-disciplinary Education in Social and Ethical Aspects of Nanotechnology, which received nearly $200,000 from the National Science Foundation?s Nano Undergraduate Education program.
Researchers have developed a simple approach of applying a surface coating of thin, flat nanoplatelets using a common spray gun, such as can be purchased off-the-shelf from an art supply store, to create a surface coating in which nanoplatelets spontaneously self-assemble into 'nano-walls'. The nano-walls act as rigid barriers that prevent oxygen gas from reaching the surface, and are effective at low and high humidity levels.
Earlier work assumed that the liquid medium in which certain self-assembling particles float could be treated as a placid vacuum, but a University of Pennsylvania team has shown that fluid dynamics play a crucial role in the kind and quality of the structures that can be made in this way.
Micro Nano MEMs 2014 is the UK's must go to showcase for micro, precision, mems and nano manufacturing technologies and will be taking place on the 30th September and 1st October at the NEC in Birmingham.
