Shell‐by‐Shell Functionalization of Inorganic Nanoparticles [PDF]
Chemistry – A European Journal, 2020 AbstractThe current state of the hierarchical chemical functionalization of inorganic nanoparticles (NPs) by shell‐by‐shell (SbS)‐assembly of organic layers around the NP cores is summarized. This supramolecular functionalization concept is based on two steps: 1) the covalent grafting of a first ligand–shell consisting of, for example, long chain ...

Discrete and Computational Geometry, 2003 The radial distribution function is a characteristic geometric quantity of a point set in Euclidean space that reflects itself in the corresponding diffraction spectrum and related objects of physical interest. The underlying combinatorial and algebraic structure is well understood for crystals, but less so for non-periodic arrangements such as ...

Physical Review D, 2002 When a potential for a scalar field has two local minima there arise spherical shell-type solutions of the classical field equations due to gravitational attraction. We establish such solutions numerically in a space which is asymptotically de Sitter.

From Shell Logs to Shell Scripts [PDF]
, 2001 Analysing the use of a Unix command shell is one of the classic applications in the domain of adaptive user interfaces and user modelling. Instead of trying to predict the next command from a history of commands, we automatically produce scripts that automate frequent tasks. For this we use an ILP association rule learner.

Geofluids, 2022 Estimating water saturation via conventional logging tool such as resistivity cannot provide an accurate solution in a formation with low conductivity water and tight porosity. As an alternative, we employed a dielectric permittivity, which makes it easy

Dynamic effects of fault modeling on stair-step and corner-point grids
Journal of Petroleum Exploration and Production Technology, 2021 Fault modeling has become an integral element of reservoir simulation for structurally complex reservoirs. Modeling of faults in general has major implications for the simulation grid.

International Journal of Geometric Methods in Modern Physics, 2004 We define on-shell symmetries and characterize them for Lagrangian systems. The terms appearing in the variation of the Poincaré–Cartan form, which vanish because of field equations, are found to be strongly constrained if the space of solutions has to be preserved.
