  • Do Columns of Azobenzene Stars Disassemble Under Light Illumination? [Journal Article]
    Langmuir 2019Koch M, Grenzer Saphiannikova M, Guskova O
  • The clustering properties of star-shaped molecules comprising three photochromic azobenzene-containing arms are investigated with specific focus on the influence of light on these structures. Previous experimental works report self-assembly of azobenzene stars in aqueous solution into long columnar clusters that are detectable using optical microscopy. These clusters appear to vanish under UV irr…
  • Neuroarchitecture of the central complex of the desert locust: Tangential neurons. [Journal Article]
    J Comp Neurol 2019von Hadeln J, Hensgen R, … Homberg U
  • The central complex (CX) comprises a group of midline neuropils in the insect brain, consisting of the protocerebral bridge (PB), the upper (CBU) and lower division (CBL) of the central body and a pair of globular noduli. It receives prominent input from the visual system and plays a major role in spatial orientation of the animals. Vertical slices and horizontal layers of the CX are formed by co…
  • Low-Dimensional Magnetic Semimetal Cr0.65Al1.35Se3. [Journal Article]
    Inorg Chem 2019; 58(20):13960-13968Marshall M, Blawat J, … Xie W
  • While exploring novel magnetic semiconductors, the new phase Cr0.65Al1.35Se3 was discovered and characterized by both structural and physical properties. Cr0.65Al1.35Se3 was found to crystallize into orthorhombic CrGeTe3-type structure with space group Pnma (no. 62). Vacancies and mixed occupancies were tested, and the results show that one of the 4c sites accommodates a mixture of Cr and Al atom…
  • Oblique angle deposition of nickel thin films by high-power impulse magnetron sputtering. [Journal Article]
    Beilstein J Nanotechnol 2019; 10:1914-1921Hajihoseini H, Kateb M, … Gudmundsson JT
  • CONCLUSIONS: Due to the high discharge current and high ionized flux fraction, the HiPIMS process can suppress the inclined columnar growth induced by oblique angle deposition. Thus, the ferromagnetic thin films obliquely deposited by HiPIMS deposition exhibit different magnetic properties than dcMS-deposited films. The results demonstrate the potential of the HiPIMS process to tailor the material properties for some important technological applications in addition to the ability to fill high aspect ratio trenches and coating on cutting tools with complex geometries.
