Calibration of Beacons for Indoor Environments based on a Digital Map and Heuristic Information.

Sensors (Basel, Switzerland)

Gualda D, Ureña J, Alcalá J, Santos C.
PMID: 30736385
Sensors (Basel). 2019 Feb 06;19(3). doi: 10.3390/s19030670.

This paper proposes an algorithm for calibrating the position of beacons which are placed on the ceiling of an indoor environment. In this context, the term calibration is used to estimate the position coordinates of a beacon related to...

Tuning the Carbon Nanotube Selectivity: Optimizing Reduction Potentials and Distortion Angles in Perylenediimides.

Journal of the American Chemical Society

Münich PW, Schierl C, Dirian K, Volland M, Bauroth S, Wibmer L, Syrgiannis Z, Clark T, Prato M, Guldi DM.
PMID: 29553719
J Am Chem Soc. 2018 Apr 25;140(16):5427-5433. doi: 10.1021/jacs.8b00452. Epub 2018 Apr 13.

Different water-soluble perylenediimides (PDIs) have been used to individualize and stabilize single-walled carbon nanotubes (SWCNTs) in aqueous media. A key feature of the PDIs is that they can be substituted at the bay positions via the addition of two...

Pre-Planarized Triphenylamine-Based Linear Mixed-Valence Charge-Transfer Systems.

Angewandte Chemie (International ed. in English)

Krug M, Fröhlich N, Fehn D, Vogel A, Rominger F, Meyer K, Clark T, Kivala M, Guldi DM.
PMID: 33306267
Angew Chem Int Ed Engl. 2021 Mar 15;60(12):6771-6777. doi: 10.1002/anie.202014567. Epub 2021 Feb 03.

Three linear dimers with two redox-active planarized triphenylamines were synthesized and their structures verified by X-ray crystallography. Their radical cations, which exhibit electron self-exchange between the two redox centers, are of great interest. This process was thoroughly investigated by...

A Family of Superhelicenes: Easily Tunable, Chiral Nanographenes by Merging Helicity with Planar π Systems.

Angewandte Chemie (International ed. in English)

Reger D, Haines P, Amsharov KY, Schmidt JA, Ullrich T, Bönisch S, Hampel F, Görling A, Nelson J, Jelfs KE, Guldi DM, Jux N.
PMID: 34014601
Angew Chem Int Ed Engl. 2021 Aug 09;60(33):18073-18081. doi: 10.1002/anie.202103253. Epub 2021 Jul 09.

We designed a straightforward synthetic route towards a full-fledged family of π-extended helicenes: superhelicenes. They have two hexa-peri-hexabenzocoronenes (HBCs) in common that are connected via a central five-membered ring. By means of structurally altering this 5-membered ring, we realized...

Frailty, MRI, and FDG-PET Measures in an Australian Memory Clinic Cohort.

Frontiers in medicine

Jordan N, Gvalda M, Cody R, Galante O, Haywood C, Yates P.
PMID: 33521008
Front Med (Lausanne). 2021 Jan 14;7:578243. doi: 10.3389/fmed.2020.578243. eCollection 2020.

Given that the global population is aging, the number of age-related syndromes, such as frailty, is expected to rise in conjunction. Frailty is characterized by the loss of homeostatic reserve, rendering the individual vulnerable to poor health outcomes. Many...
