Hexabenzocoronen‐Benzimidazol Hybrid Strukturen und Faraday Rotation des Ersten Hexabenzocoronen‐Phthalocyanins

Angewandte Chemie, Volume 138, Issue 5, 28 January 2026.
Die Synthese von vier Hexabenzocoronen‐ (HBC) Benzimidazol‐Hybridmolekülen wird gezeigt, gipfelnd in Tetra‐HBC Ni‐Phthalocyanin (Pc), dessen Anwendung als Faradayrotator eine bemerkenswerte Verdetkonstante ergibt. Die Verbindungen sind vollständig charakterisiert und ihre optoelektronischen Eigenschaften wurden mittels Elektrochemie, UV‐vis‐ und ...

Nitrogen Dioxide Sensing Using Multilayer Structure of Reduced Graphene Oxide and α-Fe₂O₃

Sensors, 2021
Multilayers consisting of graphene oxide (GO) and α-Fe2O3 thin layers were deposited on the ceramic substrates by the spray LbL (layer by layer) coating technique. Graphene oxide was prepared from graphite using the modified Hummers method.

Coloring Graphs with Forbidden Minors

, 2016
Hadwiger's conjecture from 1943 states that for every integer $t\ge1$, every graph either can be $t$-colored or has a subgraph that can be contracted to the complete graph on $t+1$ vertices. As pointed out by Paul Seymour in his recent survey on Hadwiger'

Crumpling Damaged Graphene [PDF]

Scientific Reports, 2016
AbstractThrough molecular mechanics we find that non-covalent interactions modify the fractality of crumpled damaged graphene. Pristine graphene membranes are damaged by adding random vacancies and carbon-hydrogen bonds. Crumpled membranes exhibit a fractal dimension of 2.71 ± 0.02 when all interactions between carbon atoms are considered and 2.30 ± 0 ...

Charakterisierung der N‐Methyltransferase SgPsmC: Anwendung in der kinetischen Racematspaltung von Pyrroloindolinen

Angewandte Chemie, Volume 138, Issue 2, 9 January 2026.
Die N‐Methyltransferase SgPsmC wurde charakterisiert und für die kinetische Racematspaltung von Pyrroloindolinen verwendet. Die Substitution an 3a‐Position erwies sich als eine Hauptdeterminante für die Enantioselektivität des Enzyms. Die Reaktion wurde mit einer Methionin‐Adenosyl‐Transferase gekoppelt, um S‐Adenosylmethionin in situ zu erzeugen und ...

Sind i‐Motiv‐Strukturen in DNA kompatibel mit Cytosin–Ag(I)–Cytosin‐Basenpaaren?

Angewandte Chemie, Volume 138, Issue 2, 9 January 2026.
Ein i‐Motiv/Duplex‐Konjugat wurde hinsichtlich seiner Fähigkeit untersucht, die Protonen der hemiprotonierten C:CH+‐Basenpaare durch AgI‐Ionen zu ersetzen, um C–AgI–C‐Basenpaare zu bilden. Interessanterweise wird nur ein einziges solches Basenpaar gebildet, bevor sich das Oligonukleotid in eine Duplexstruktur umlagert.

Layered patterns in nature, medicine, and materials: quantifying anisotropic structures and cyclicity [PDF]

PeerJ, 2019
Various natural patterns—such as terrestrial sand dune ripples, lamellae in vertebrate bones, growth increments in fish scales and corals, aortas and lamellar corpuscles in humans and animals—comprise layers of different thicknesses and lengths ...

Water-Gated Charge Doping of Graphene Induced by Mica Substrates

, 2012
We report on the existence of water-gated charge doping of graphene deposited on atomically flat mica substrates. Molecular films of water in units of ~0.4 nm-thick bilayers were found to be present in regions of the interface of graphene/mica hetero ...

Graphene and graphene oxide for desalination

Nanoscale, 2016
There is a huge scope for graphene-based materials to be used as membranes for desalination. A very recent study has confirmed that 100% salt rejection can be achieved for commonly used ions by utilizing single layer nonporous graphene. However, the cost effective fabrication procedure for graphene oxide membranes with precise control of pore size can ...
