Herein we demonstrate the favorable synergistic effect of an NH4Cl additive and DMSO solvent on 2D perovskites that are synthesized at room temperature. Interestingly, we observe the spontaneous formation of 3D phases within either NH4Cl or DMSO treated 2D perovskites, which plays a pivotal role in facilitating charge transport. It is revealed that NH4Cl increases charge carrier lifetime and passi
We examine the index data associated to twisted spectral triples and higher order spectral triples. In particular, we show that a Lipschitz regular twisted spectral triple can always be “logarithmically dampened” through functional calculus, to obtain an ordinary (i.e. untwisted) spectral triple. The same procedure turns higher order spectral triples into spectral triples. We provide examples of h
A porphyrin -system has been modulated by enhancing the push-pull character with highly asymmetrical substitution for dye-sensitized solar cells for the first time. Namely, both two diarylamino moieties as a strong electron-donating group and one carboxyphenylethynyl moiety as a strong electron-withdrawing, anchoring group were introduced into the meso-positions of the porphyrin core in a lower sy
By joining Studentlund, students in Helsingborg get access to student life in Lund. In addition to this, students in Lund can join organisations that are unique to Helsingborg. Helsingborg was ranked the third best student city in Sweden 2023 by Studentum.More about StudentlundStudent unions for social science and engineering studentsThere are two large student unions for students in Helsingborg.I

Although the hippocampus is one of the most studied structures in the human brain, limited quantitative data exist on its 3D organization, anatomical variability, and effects of disease on its subregions. Histological studies provide restricted reference information due to their 2D nature. In this paper, high-resolution (∼200 × 200 × 200 μm3) ex vivo MRI scans of 31 human hippocampal specimens are
Methods have been developed for the isolation on a semi-micro scale of a plasma membrane-enriched fraction from rat islets of Langerhans. An important feature of these experiments is the use of 125I-labeled wheat germ agglutinin as a specific probe for plasma membrane-containing fractions. The partly purified plasma membrane fraction had a density in sucrose of about 1.10 and was enriched in the a
Lund University is home to unique museums, collections and archives that reflect both research and history. Here you will find everything from archaeological finds, art and historical documents to biological diversity and type specimens. Skissernas MuseumSkissernas Museum – the Museum of Artistic Process and Public Art – is a unique art museum focusing on the artistic creative process. It houses t
