Electrochemical electron beam lithography: Write, read, and erase metallic nanocrystals on demand
We develop a solution-based nanoscale patterning technique for site-specific deposition and dissolution of metallic nanocrystals. Nanocrystals are grown at desired locations by electron beam-induced reduction of metal ions in solution, with the ions supplied by dissolution of a nearby electrode via an applied potential. The nanocrystals can be "erased" by choice of beam conditions and regrown r...
متن کاملEpigenetic Modulation Mechanisms in Psychiatric Disorders: Gene and Trigger and Erase and Re-write Hypothesis
Epigenetic modifications are investigated routinely and are one of the most rapidly growing components of molecular biology. Epigenetics has also been implicated in brain and behavior. Psychiatric disorders with complex etiologies have recently been attributed to specific epigenetic alterations in gene expression patterns leading up to behavioral maladaptations. This field has also provided a n...
متن کاملA selective fluoride sensor and a digital processor with "Write-Read-Erase-Read" behaviour.
An easy-to-synthesize Schiff base as a selective and colorimetric fluoride sensor via modulation of intramolecular charge transfer (ICT) has been demonstrated. A typical dual-ion binding property along with its distinct reversibility has been explored for YES, NOR and INH logic functions and a potential "Write-Read-Erase-Read" mimic.
متن کاملRead-Write-Erase: Mobile-mediated publics in South Africa’s 2009 elections
This paper describes four kinds of mobile mediated political participation observed during the 2009 national elections in South Africa: (1) SMS ‘wars’ in the run-up to the election; (2) .mobi websites hosted by political parties; and the political content included on (3) the mobile social network Mig33 and excluded from (4) its counterpart/competitor, MXit. We discuss the failure of all four fo...
متن کاملNanolithographic write, read, and erase via reversible nanotemplated nanostructure electrodeposition on alkanethiol-modified Au(111) in an aqueous solution.
A write, read, and erase nanolithographic method, combining in situ electrodeposition of metal nanostructures with atomic force microscopy (AFM) nanoshaving of a 1-hexadecanethiol (HDT) self-assembled monolayer (SAM) on Au(111) in an aqueous solution, is reported. The AFM tip defines the local positioning of nanotemplates via the irreversible removal of HDT molecules. Nanotemplates with lateral...
