Only 58% of the project records used to populate our database had information on project
costs. For this subset, total costs came to $9.1 billion. Most of this was spent after 1990, with …

Fluorescence lifetimes of single Rhodamine 6G molecules on silica surfaces were
measured with pulsed laser excitation, time-correlated single photon counting, and near-field …

Building on previous environmental flow discussions and a growing recognition that
hydrogeomorphic processes are inherent in the ecological functionality and biodiversity of …

According to the hypothesis of punctuated aggradational cycles presented here, the
stratigraphic record consists of small-scale (1-5 m thick) shallowing-upward cycles (PACs) …

Organometallic halide perovskites CH 3 NH 3 PbX 3 (X = I, Br, Cl) have quickly become one
of the most promising semiconductors for solar cells, with photovoltaics made of these …

Over the past five years, several groups have developed the capability to detect and identify
single fluorescent molecules in solution as the molecules flow through a focused laser beam…

We report the first photobleaching experiments of single molecules on a surface. Single
molecules of rhodamine 6G are detected on a silica surface under ambient conditions using near…

Small silver clusters that form with short oligonucleotides are distinguished by their strong
fluorescence. Previous work showed that red- and blue/green-emitting species form with the …

Large, fluorescently stained restriction fragments of lambda phage DNA are sized by passing
Individual fragments through a focused continuous wave laser beam In an ultrasensitive …

We recently developed an inorganic shell approach for suppressing blinking in nanocrystal
quantum dots (NQDs) that has the potential to dramatically improve the utility of these …
