Shell‐by‐Shell Functionalization of Inorganic Nanoparticles [PDF]

open access: yesChemistry – 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 ...

The Effect of Negative-Energy Shells on the Schwarzschild Black Hole [PDF]

open access: yes, 2009
We construct Penrose diagrams for Schwarzschild spacetimes joined by massless shells of matter, in the process correcting minor flaws in the similar diagrams drawn by Dray and 't Hooft, and confirming their result that such shells generate a horizon ...

Formation and Incidence of Shell Galaxies in the Illustris Simulation [PDF]

open access: yes, 1949
Shells are low surface brightness tidal debris that appear as interleaved caustics with large opening angles, often situated on both sides of the galaxy center.

Overwintering of Spiders in Terrestrial Molluscs Shells in the Wider Area of Vranov nad Topľou (Slovakia)

open access: yesActa Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2017
Overwintering of spiders in empty snail shells is a little studied topic and in Slovakia similar research has not been carried out yet. Collecting shells was carried out in the eastern part of Slovakia, in winter at the turn of 2012/2013 and 2013/2014 ...

From Shell Logs to Shell Scripts [PDF]

open access: yes, 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.

HI shells in the Leiden/Argentina/Bonn HI survey [PDF]

open access: yes, 2013
We analyse the all-sky Leiden/Argentina/Bonn HI survey, where we identify shells belonging to the Milky Way. We used an identification method based on the search of continuous regions of a low brightness temperature that are compatible with given ...

Partitioning of trace metals between soft tissues and shells of Patella aspera [PDF]

open access: yes, 2004
This paper describes the partitioning of iron, manganese, zinc, copper, cadmium, cobalt, nickel and lead between the soft tissues and the shells of the gastropod mollusc Patella aspera. Specimens of the limpet P aspera were collected from a clean coastal

HST/ACS observations of shell galaxies: inner shells, shell colours and dust [PDF]

open access: yes, 2007
AIM:Learn more about the origin of shells and dust in early type galaxies. METHOD: V-I colours of shells and underlying galaxies are derived, using HST Advanced Camera for Surveys (ACS) data.

A new algorithm for near–singular integration of 3D Boundary Element Integrals for thin–walled elements

open access: yesRevista Facultad de Ingeniería Universidad de Antioquia, 2015
The accuracy of the Boundary Element Method (BEM) is strongly dependent on an accurate evaluation of boundary integrals. For thin-walled structures, collocation points and integration elements are often very close, making the kernel of the integrations ...

The asymptotically sharp Korn interpolation and second inequalities for shells [PDF]

open access: yes, 2018
We consider shells in three dimensional Euclidean space which have bounded principal curvatures. We prove Korn's interpolation (or the so called first and a half\footnote{The inequality first introduced in [6]}) and second inequalities on that kind of ...
