Relaxation Constants and Relaxivities as Biomarkers in NMR Imaging: Biochemical-NMR Correlation in Medicine

A systematic review on NMR relaxation constants with clinical applications has been performed based on current recommendations by publishers and foundations. An exhaustive overview of currently used NMR techniques and their potential in radiology sciences was obtained by creating a search strategy and explicit inclusion and exclusion criteria.

Beyond excitation NMR relaxation

Concepts in Magnetic Resonance Part A, 2008
AbstractThe understanding of NMR relaxation processes allows us to comprehend a variety of experiments ranging from the recording of spectra to the determination of images. A brief history of NMR spectroscopy, the state of the art of this technique, as well as its comparison with the coupling constants and chemical shifts measured in the condensed ...

Liquid Crystal Elastomer Actuator Matrix for Large Area Applications

Advanced Materials Technologies, EarlyView.
A scalable approach is used to manufacture a digitally‐controllable, 2D 5 × 5 actuator matrix. The elements of the matrix are produced by direct ink writing of a liquid crystal elastomer ‘artificial muscle’ on large‐area flexible thin‐film heaters. In optimizing the low‐power actuators, multiple heater designs and substrate materials are investigated ...

A Layered Two‐Dimensional Hydrogen‐Bonded Organic Framework Based on 2,5,8,11‐Tetrakis(4‐Carboxyphenyl)Perylene Diimide: Structural Nature, Optical and Photophysical Properties

Advanced Optical Materials, EarlyView.
A novel hydrogen‐bonded organic framework (HOF) based on perylene diimide (PDI) is synthesized, structurally and spectroscopically characterized. Its photophysical behavior highlights how supramolecular organizations govern the optical properties, including emission from monomers, aggregates, and excimer‐like species. Structural transformations induced

NMR-basierte strukturelle und dynamische Untersuchungen an nicht-nativen Varianten des Hühnereiweißlysozyms [PDF]

, 2007
Die Erforschung nicht-nativer Zustände von Proteinen hat bisher viele Erkenntnisse zum besseren Verständnis der Proteinfaltung und -fehlfaltung erbracht. Die Kernmagnetische Resonanzspektroskopie (NMR) ist die einzige bekannte Methode, die zur Aufklärung

Ligand‐Dependent Locally Excited and Charge‐Transfer Emission in Linear Copper(I) Mesoionic Carbene Luminophores

Advanced Optical Materials, EarlyView.
Ligand engineering enables precise control of emission in linear Cu(I) complexes by tuning donor–acceptor interactions between electron‐rich amines and π‐accepting mesoionic carbenes. Naphthyl‐substituted carbenes promote locally excited phosphorescence with vibronic structure, whereas electron‐rich amides combined with electron‐poor carbenes favor ...

Heteroleptic Ag(I) Complexes Bearing Benzothiazole and Benzoxazole Ligands for Orange‐Red Light‐Emitting Electrochemical Cells

Advanced Optical Materials, EarlyView.
Light‐emitting Electrochemical Cells (LECs) are appealing electroluminescent devices with potential application in low‐cost, large‐area display technology and disposable devices. In the manuscript, a novel family of bright photo‐ and electro‐active heteroleptic silver(I) is presented and comprehensively investigated.
