A series of pyridine-functionalized poly (N-isopropylacrylamide)- based microgels were synthesized. Subsequently, a structured photonic device was fabricated by sandwiching the microgels between two thin Au layers, and their response to CO2 investigated. We show that devices show an optical...

On a perfect hydrogen-terminated Si(100)-2x1 surface, each surface silicon atom is capped with exactly one atom of hydrogen. When one of the capping hydrogen atoms is removed, the now unsatisfied orbital of the underlying silicon atom is exposed at that site. This site is better known as a...

Serpe, Michael J., Xu, Wenwen, Gao, Yongfeng
Poly (N-isopropylacrylamide-co-acrylic acid) (pNIPAm-co-AAc) microgel-based free-standing etalons have been developed by fabricating etalons on a solid support that has been coated with a sacrificial polymer layer. Therefore, the etalon could be easily removed from the solid substrate upon...

Nanomechanical torque magnetometry is emerging as a highly-sensitive method for gauging magneto-statics and magnetic dynamics in mesoscopic and nano-scale magnetic materials. Advances in torque magnetometry are presented here, which were unattainable using previ- ous techniques. Silicon nitride...
