Journal ArticleDOI
Level set calculations of the evolution of boundaries on a dynamically adaptive grid
TL;DR: An efficient and robust coupling of a hierarchical space description structure with the state-of-the-art level set method is established and a controllable finite-width region of the highest resolution straddling the physically important boundary is established.
Journal ArticleDOI
Alkyl Xanthates: New Capping Agents for Metal Colloids. Capping of Platinum Nanoparticles
TL;DR: In this paper, the properties of long-chain alkyl xanthate-capped platinum nanoparticles were investigated and it was shown that these particles exhibit a characteristic sharp absorption in the range 450−470 nm in addition to the extinction in the UV.
Journal ArticleDOI
The effect of large electric field gradients on the Raman optical activity of molecules adsorbed on metal surfaces
TL;DR: In this paper, the effect of large electric field gradients near metal surfaces on Raman optical activity (ROA) of adsorbed molecules is discussed, and it is shown that large gradients would cause unusually high values of the measured circular intensity differences, orders of magnitude higher than those measured in solution.
Journal ArticleDOI
Outer‐sphere electron‐transfer reactions in polar solvents
Shlomo Efrima,Mordechai Bixon +1 more
TL;DR: In this paper, a model for outer-sphere electron transfer reactions in polar solutions is proposed based on the idea of dividing the system into two subsystems, a classical solvent and quantum mechanical interacting molecules.
Journal ArticleDOI
Hierarchical assembly of ultranarrow alkylamine-coated ZnS nanorods: a synchrotron surface X-ray diffraction study.
Nataly Belman,Somobrata Acharya,Oleg Konovalov,Alexei Vorobiev,Jacob N. Israelachvili,Shlomo Efrima,Yuval Golan +6 more
TL;DR: A hierarchical "packing model" is proposed, based on GISAXS, transmission electron microscopy, thermogravimetric analysis, and grazing incidence X-ray diffraction of pure surfactant Langmuir films, which revealed the formation of ordered superstructures on the water surface consisting of alternating nanoparticles.
