Apply now: Ferienakademie Sarntal 2017

The Ferienakademie is a summer school with a long tradition organized by three universities in Bavaria and Baden-Württemberg. It is an excellent opportunity to spend two weeks in late summer/early fall in the Tyrol mountains (northern Italy) to learn and explore science, coding, and nature.

This year Nils Thurey (TU Munich), Miriam Mehl (Uni Stuttgart), and Michael Engel are offering a course on the topic “Creating Animations by Machine Learning and Simulation” to Master’s students in computer science, engineering, math, physics, and chemistry.

The dates of the course are: 17.09. – 29.09.2017.
Application is now open until 9 May 2017.

Two high-impact publications

We are very excited about two new nanoparticle publications in top-level journals, a review article on self-assembly in Chemical Reviews and an upcoming paper about quasicrystals in Nature Materials:

“Chemical methods developed over the past two decades enable preparation of colloidal nanocrystals with uniform size and shape. These Brownian objects readily order into superlattices. Recently, the range of accessible inorganic cores and tunable surface chemistries dramatically increased, expanding the set of nanocrystal arrangements experimentally attainable. In this review, we discuss efforts to create next-generation materials via bottom-up organization of nanocrystals with preprogrammed functionality and self-assembly instructions. […]”

Self-Assembly of Colloidal Nanocrystals: From Intricate Structures to Functional Materials
M.A. Boles, M. Engel, D.V. Talapin
Chemical Reviews 116, 11220-11289 (2016)

“Expanding the library of self-assembled superstructures provides insight into the behaviour of atomic crystals and supports the development of materials with mesoscale order. Here we build on recent findings of soft matter quasicrystals and report a quasicrystalline binary nanocrystal superlattice that exhibits correlations in the form of partial matching rules reducing tiling disorder. We determine a three-dimensional structure model through electron tomography and direct imaging of surface topography. […]”

Photonic band gap paper appears in PRL

“We study photonic band gap formation in two-dimensional high-refractive-index disordered materials where the dielectric structure is derived from packing disks in real and reciprocal space. Numerical calculations of the photonic density of states demonstrate the presence of a band gap for all polarizations in both cases. We find that the band gap width is controlled by the increase in positional correlation inducing short-range order and hyperuniformity concurrently. Our findings suggest that the optimization of short-range order, in particular the tailoring of Bragg scattering at the isotropic Brillouin zone, are of key importance for designing disordered PBG materials.”
