Negative index of refraction in optical metamaterials
A double-periodic array of pairs of parallel gold nanorods is shown to have a negative refractive index in the optical range. Such behavior results from the plasmon resonance in...

Functionalized Carbon Nanotubes: Properties and Applications
Carbon nanotubes can be functionalized via amidation and esterification of the nanotube-bound carboxylic acids. The solubility of these functionalized carbon nanotubes makes it ...
Metal Halide Perovskite Nanocrystals: Synthesis, Post-Synthesis Modifications, and Their Optical Properties
Metal halide perovskites represent a flourishing area of research, which is driven by both their potential application in photovoltaics and optoelectronics and by the fundamenta...
The cost of a cloud
The data centers used to create cloud services represent a significant investment in capital outlay and ongoing costs. Accordingly, we first examine the costs of cloud service d...
Single Silver Nanoparticles as Real-Time Optical Sensors with Zeptomole Sensitivity
This work utilizes dark-field optical microscopy to demonstrate the localized surface plasmon resonance ìmax response of individual Ag nanoparticles to the formation of a monola...
Gate-Variable Optical Transitions in Graphene
Two-dimensional graphene monolayers and bilayers exhibit fascinating electrical transport behaviors. Using infrared spectroscopy, we find that they also have strong interband tr...
Solitons in Optical Communications
Abstract Solitons are a fascinating topic for study and a major source of interest for potential application in optical communication. Possibly the first observation of a solito...
Three-Dimensional Optical Storage Memory
A novel three-dimensional (3-D) optical memory device is presented that allows fast random access of the information and extremely high bit densities. This device is based on tw...
Coral bleaching: the winners and the losers
Sea surface temperatures were warmer throughout 1998 at Sesoko Island, Japan, than in the 10 preceding years. Temperatures peaked at 2.8 °C above average, resulting in extensive...
Transfer Learning for Reinforcement Learning Domains: A Survey
The reinforcement learning paradigm is a popular way to address problems that have only limited environmental feedback, rather than correctly labeled examples, as is common in o...
