Technical and experimental features of Magnetic Resonance Spectroscopy of brain glycogen metabolism

Rolf Gruetter, Hongxia Lei, Ana Francisca Leal Silva Soares

In the brain, glycogen is a source of glucose not only in emergency situations but also during normal brain activity. Altered brain glycogen metabolism is associated with energetic dysregulation in pathological conditions, such as diabetes or epilepsy. Bot ...

Local Structures and Heterogeneity of Silica-Supported M(III) Sites Evidenced by EPR, IR, NMR, and Luminescence Spectroscopies

David Lyndon Emsley, Aaron James Rossini

Grafting molecular precursors on partially dehydroxylated silica followed by a thermal treatment yields silica-supported M(III) sites for a broad range of metals. They display unique properties such as high activity in olefin polymerization and alkane dehy ...

Creatine in the central nervous system: From magnetic resonance spectroscopy to creatine deficiencies

Cristina Ramona Cudalbu, Veronika Rackayová

Creatine (Cr) is an important organic compound acting as intracellular high-energy phosphate shuttle and in energy storage. While located in most cells where it plays its main roles in energy metabolism and cytoprotection, Cr is highly concentrated in musc ...

Indium selenide: an insight into electronic band structure and surface excitations

Davide Campi

We have investigated the electronic response of single crystals of indium selenide by means of angle-resolved photoemission spectroscopy, electron energy loss spectroscopy and density functional theory. The loss spectrum of indium selenide shows the direct ...

Amyloid Fibril Polymorphism: Almost Identical on the Atomic Level, Mesoscopically Very Different

Henning Paul-Julius Stahlberg

Amyloid polymorphism of twisted and straight beta-endorphin fibrils was studied by negative-stain transmission electron microscopy, scanning transmission electron microscopy, and solid-state nuclear magnetic resonance spectroscopy. Whereas fibrils assemble ...

Full Color Generation Using Silver Tandem Nanodisks

Olivier Martin, Christian Santschi, Chen Yan, Xiaolong Wang, Hao Wang, Jingwen Zhang, Hua Zhao

Plasmonic effects associated with metallic nanostructures have been widely studied for color generation. It became apparent that highly saturated and bright colors are hard to obtain, and very small nanostructures need to be fabricated. To address this iss ...

Correlation-driven transport asymmetries through coupled spins in a tunnel junction

Klaus Kern, Markus Ternes

Spin-spin correlations can be the driving force that favours certain ground states and are key in numerous models that describe the behaviour of strongly correlated materials. While the sum of collective correlations usually lead to a macroscopically measu ...

Adverse environmental and social conditions early in life have a strong impact on health. They are major risk factors for mental diseases in adulthood and, in some cases, their effects can be transmitted across generations. The consequences of detrimental ...

Exchange anisotropy in the skyrmion host GaV4S8

Dirk Grundler

Using ferromagnetic resonance spectroscopy at 34 GHz we explored the magnetic anisotropy of single-crystalline GaV4S8 in the field-polarized magnetic state. We describe the data in terms of an easy-axis type uniaxial anisotropy with an anisotropy constant ...

Dressed photon-orbital states in a quantum dot: Intervalley spin resonance

Pasquale Scarlino

The valley degree of freedom is intrinsic to spin qubits in Si/SiGe quantum dots. It has been viewed alternately as a hazard, especially when the lowest valley-orbit splitting is small compared to the thermal energy, or as an asset, most prominently in pro ...
