Abstract:

Ten species of marine strombidiid ciliates were identified after protargol staining plankton samples. The taxonomic redescriptions include a diagnosis for Tontonia gracillima Faure-Fremiet, 1924, Strombidium wulffi (Wulff, 1919) Kahl, 1932, Strombidium acutum Leegaard, 1915, Strombidium constrictum (Meunier, 1910) Wulff, 1919, Strombidium compressum (Leegaard, 1915) Kahl, 1932, and Strombidium sulcatum Claparede & Lachmann, 1858. Four new species, Strombidium dalum n.sp., Strombidium epidemum n.sp., Strombidium rhynchum n.sp., and Strombidium tressum n.sp., are defined based primarily on the characteristics of the anterior oral polykinetids, numbers of oral polykinetids, and presence of anterior protuberance.

Abstract:

In this paper we analyze the stability properties of the Wulff-shape in the crystalline flow. It is well known that the Wulff-shape evolves self-similarly, and eventually shrinks to a point. We consider the flow restricted to the set of convex polyhedra, we show that the crystalline evolutions may be viewed, after a proper rescaling, as an integral curve in the space of polyhedra with fixed volume, and we compute the Jacobian matrix of this field. If the eigenvalues of such a matrix have real part different from zero, we can determine if the Wulff-shape is stable or unstable, i.e. if all the evolutions starting close enough to the Wulff-shape converge or not, after rescaling, to the Wulff-shape itself.

Abstract:

The phenomenon of the Court Jew does not cease to fascinate us. Our attention is at first drawn by the contrast of Jews as advisers and confidantes to princes and monarchs, not infrequently in a kingdom or duchy which otherwise forbade residence to Jews, or, if it did allow it, segregated them in ghettos with the concomitant disabilities that results from such a status. The image of these court factors (Hoffaktor, Hofjude) is further enhanced by their use of the trappings of the eighteenth century nobility, while, more often than not, they not only adhered to the faith of their fathers, but actively worked for and interceded on behalf of their co-religionists.

Abstract:

Wulff Dieter Heintz, Professor Emeritus of Astronomy at Swarthmore College, passed away at his home on 10 June 2006, following a two-year battle with lung cancer. He had just turned 76 a week earlier. Wulff was one of the leading authorities on visual double stars, and was also a chess master. A prominent educator, researcher, and scholar, Wulff was noted for being both succinct and meticulous in everything he did. Wulff Heintz was born on 3 June 1930 in Würzburg (Bavaria), Germany. Naturally left-handed, the young Wulff's elementary school teachers forced him to learn to write “correctly” using his right hand, and so he became ambidextrous. During the 1930s, Wulff's family saw the rise of Adolph Hitler and lived under the repressive Nazi regime. Conditions were austere, and it was often difficult to find fuel to keep the house warm. As a teenager during World War II, Wulff listened to his family radio for any news from the outside world. He used to say that he loved the blackouts during the bombing runs because it made it much easier to see the stars. One night, an incendiary bomb landed on the roof of his family home, and Wulff climbed up to the roof and extinguished it. The next morning, he saw that his high school had been completely leveled by Allied bombs. As Germany continued to suffer massive losses on the Russian Front, primarily due to unexpectedly severe winters, teenage boys were inducted into the military and sent off to replenish the troops. To avoid an uncertain fate, Wulff hid out in a farmhouse in the countryside outside Munich. When the Allied troops invaded Germany in 1945, the young Wulff volunteered to translate information from the American and British soldiers to the local villagers. During this time, the soldiers taught Wulff how to smoke cigarettes, a habit which he continued until his final days, even after having been diagnosed with lung cancer.

Abstract:

You are in Osu, Accra. As you walk along Castle Drive toward Christiansborg Castle, there is row of four houses on your left and a large open field on your right. The field, with the grass carefully tended, is the locus of the old Danish cemetery, where the gravestones that remained have been mounted into a low wall built on the sea side of the field. Across the street, one of the houses, the second one from your starting point, has a stone name plate over the main door bearing the inscription: FREDERICHS MINDE 1840 W.I.WULFF. Scandinavians who have visited Ghana know about this house. They know that it was built by a Danish civil servant who had worked for the Danish Board of Trade, that he had established a family there, and they may know that he died of illness there at the age of thirty-three. They also know that by simply going to the door and knocking they will be welcomed and permitted to look around.The residents of the house—and indeed it is a residence—who so graciously receive unexpected and unannounced visitors, are at present members of the Wulff-Cochrane family. When I was last there it was Mr. and Mrs. Leslie Wulff-Cochrane who opened the doors to me and my three friends. We were shown around the house, treated to the fine view of the ocean from the living room, and then taken down into the basement to see the singular element of the house, the grave of Wulff J. Wulff.

Abstract:

Background: The majority of complex and advanced materials contain nanoparticles. The properties of these materials depend crucially on the size and shape of these nanoparticles. Wulff construction offers a simple method of predicting the equilibrium shape of nanoparticles given the surface energies of the material. Results: We review the mathematical formulation and the main applications of Wulff construction during the last two decades. We then focus to three recent extensions: active sites of metal nanoparticles for heterogeneous catalysis, ligand-protected nanoparticles generated as colloidal suspensions and nanoparticles of complex metal hydrides for hydrogen storage. Conclusion: Wulff construction, in particular when linked to first-principles calculations, is a powerful tool for the analysis and prediction of the shapes of nanoparticles and tailor the properties of shape-inducing species.

Abstract:

The cohesive energy of W and Mo nanoparticles is modeled by considering W and Mo nanoparticles as Wulff construction. The energetic characteristics of Wulff construction is described by accounting for bond number in a system. The model predictions are consistent with the corresponding experimental results, especially when the diameter of nanoparticle is smaller than 1nm, which implies the closed packed structure for small nanoparticles.

Abstract:

Abstract We derive a sharp scaling law for deviations of edge-isoperimetric sets in the lattice $${\mathbb {Z}}^d$$ Z d from the limiting Wulff shape in arbitrary dimensions. As the number n of elements diverges, we prove that the symmetric difference to the corresponding Wulff set consists of at most $$O(n^{(d-1+2^{1-d})/d})$$ O ( n ( d - 1 + 2 1 - d ) / d ) lattice points and that the exponent $$(d-1+2^{1-d})/d$$ ( d - 1 + 2 1 - d ) / d is optimal. This extends the previously found ‘$$n^{3/4}$$ n 3 / 4 laws’ for $$d=2,3$$ d = 2 , 3 to general dimensions. As a consequence we obtain optimal estimates on the rate of convergence to the limiting Wulff shape as n diverges.

Abstract:

Graphene samples are identified as minimizers of configurational energies featuring both two- and three-body atomic-interaction terms. This variational viewpoint allows for a detailed description of ground-state geometries as connected subsets of a regular hexagonal lattice. We investigate here how these geometries evolve as the number [Formula: see text] of carbon atoms in the graphene sample increases. By means of an equivalent characterization of minimality via a discrete isoperimetric inequality, we prove that ground states converge to the ideal hexagonal Wulff shape as [Formula: see text]. Precisely, ground states deviate from such hexagonal Wulff shape by at most [Formula: see text] atoms, where both the constant [Formula: see text] and the rate [Formula: see text] are sharp.

Abstract:

Understanding the structure of nanoparticles is a problem with over a century of history from the first analysis by Wulff which was only proved during WWII by von Laue with the extension for supported particles on a flat substrate by Winterbottom. All these analyses have focused on single crystals, but often nanoparticles have different structures as first shown by of Ino and Ogawa who published just ahead of Allpress and Sanders. These structures, called multiply-twinned particles or MTPs remained incompletely understood until a variant of a Wulff construction was shown to explain their equilibrium shapes. Given the growth of nanotechnology in the last decades, significant advances in synthesis and characterization methods have been made so it is time to return to some of these topics and look further. It appears there is still a fair amount of science left to be done, ranging from Wulff shapes for alloys to understanding the growth shapes of nanoparticles based upon a kinetic variant of the modified Wulff construction. Some recent results such as finite size effects for alloys and single-phase nanoparticles as well as corner rounding and how these couple to the chemical potential and substrate interfacial energy, as well as how these relate to applied topics such as nanoplasmonics and face-selective catalysis will be described.

Abstract:

SynopsisThe Wulff problem is a generalisation of the isoperimetric problem and is relevant for the equilibrium of (small) elastic crystals. It consists in minimising the (generally anisotropic) surface energy among sets of given volume. A solution of this problem is given by a geometric construction due to Wulff. In the class of sets of finite perimeter this was first shown by J. E. Taylor who, using methods of geometric measure theory, also proved uniqueness. Here a more analytic uniqueness proof is presented. The main ingredient is a sharpened version of the Brunn–Minkowski inequality.

Abstract:

Diffusional growth of the grain boundary (GB) groove permits one to measure the ratio between GB energy sGB and surface energy ssur. The faceting of twin tilt grain boundaries in Cu has been studied using the GB thermal groove method. No rough facet edges were observed. It means that melting temperature is lower than the roughening temperature for the observed facets in Cu. The influence of orientation and misorientation deviation Dq = ½q – qS½ from coincidence misorientation qS has been studied. By increase of Dq the energy of (100)CSL facet increases. The convenient method for construction 3D three-dimensional Wulff diagrams was found. The 3- dimensional Wulff diagrams were constructed using this method and measured sGB / ssur values.

Nine ichnospecies are recorded from the lower part of the Wulff Land Formation (Early Wenlock) on the east side of the valley north of Apollo Sø in Wulff Land, western North Greenland. There, the formation consists of a siliciclastic slope sequence of dark grey mudstones interbedded with subordinate siltstones and sandstones. The trace fossils are: cf. Chondrites ichnosp., Gordia marina, Helminthopsis ichnosp., Megagrapton irregulare, Muensteria ichnosp., Neonereites multiserialis ichnosp. nov., Nereites jacksoni, Paleodictyon (Glenodictyon) imperfectum and Paleodictyon ichnosp. In addition to containing a new ichnospeciesy the assemblage documents only the second detailed account of trace fossils in Lower Palaeozoic slope sequences; most of the ichnospecies have not been recorded previously in such sequences.

Abstract:

The mechanism of preferential nucleation of [1{\overline 1}0{\overline 3}]-oriented GaN faceted twins on an SiO2-patternedm-plane sapphire substrate was investigated. Each variant of twins, which were enclosed byc- andm-facets, was observed to be preferentially nucleated over the opposite sides of an SiO2pattern. It was hypothesized, from the fact that the same method of Legendre transformation is applied to a Wulff plot and a kinetic Wulff plot to determine the growth morphology of a crystalline domain, that theeffectivesurface energy ofc- andm-facets would be proportional to the growth rate of the respective facet. On the basis of this hypothesis, minimization of the effective surface energy of a nucleated domain was proposed as a mechanism of preferential nucleation. This proposed mechanism successfully explained the preferential nucleation behaviour.

Abstract:

AbstractWe prove that a closed convex hypersurface of the Euclidean space with almost constant anisotropic first and second mean curvatures in the Lp-sense is W2,p-close (up to rescaling and translations) to the Wulff shape. We also obtain characterizations of geodesic hyperspheres of space forms improving those of [10] and [11].
