Watching single nanoparticles grow in real time through supercontinuum spectroscopy.
A fast dark-field scattering technique capturing full broadband spectra with millisecond time-resolution enables us to monitor the growth or assembly of single nano-objects in situ and in real time. Applying this technique to study the growth of single gold nanorods, together with scanning electron microscopy and finite-difference time-domain simulations, reveals precise quantitative informatio...
متن کاملWatching the Daisies Grow: from Biology to Biomathematics and Bioinformatics — Alan Turing Centenary Special Issue
Preface We can only see a short distance ahead, but we can see plenty there that needs to be done. Year 2012 is both the centenary of Alan Turing's birth and the 60th anniversary of the famous paper The Chemical Basis of Morphogenesis, in which he established foundations of the mathematical theory of biological and chemical pattern formation. The story started much earlier, in spring 1923, as d...
متن کاملWatching polymers grow: real time monitoring of polymerizations via an on-line ESI-MS/microreactor coupling.
A technique for the continuous on-line monitoring of polymerization processes by electrospray ionization mass spectrometry (ESI-MS) is presented via coupling with a commercial microreactor system. The potential is demonstrated by monitoring polymerizations in real time under synthesis conditions. Furthermore, a single acrylate monomer insertion into a oligo-RAFT agent, as used in the synthesis ...
متن کاملWatching mesoporous metal films grow during templated electrodeposition with in situ SAXS.
In this paper, we monitor the real-time growth of mesoporous platinum during electrodeposition using small-angle X-ray scattering (SAXS). Previously, we have demonstrated that platinum films featuring the 'single diamond' (Fd3m) morphology can be produced from 'double diamond' (Pn3m) lipid cubic phase templates; the difference in symmetry provides additional scattering signals unique to the met...
متن کاملWatching language grow in the manual modality: nominals, predicates, and handshapes.
All languages, both spoken and signed, make a formal distinction between two types of terms in a proposition--terms that identify what is to be talked about (nominals) and terms that say something about this topic (predicates). Here we explore conditions that could lead to this property by charting its development in a newly emerging language--Nicaraguan Sign Language (NSL). We examine how hand...
