Long-life plastic optical fiber probes for scanning near-field optical microscope

Giovanni Dietler, Anton Smirnov, Ekaterina Rostova

Nowadays, sharpened glass fiber - made probes attached to a quartz tuning fork (TF) and exploiting the shear force - based feedback are by far the most popular in the field of SNOM. These probes are expensive, very fragile and their fabrication is difficul ...

Aqueous phase homogeneous formic acid disproportionation into methanol

Gabor Laurenczy, Katerina Stefania Sordakis

Herein we describe formic acid disproportionation into methanol with a homogeneous iridium catalyst. Methanol yields of up to 74% were obtained in D2O at 50 °C. Initial H2 pressures further enhanced methanol formation, resulting in a highly concentrated 9. ...

Direct noninvasive estimation of myocardial tricarboxylic acid cycle flux in vivo using hyperpolarized 13C magnetic resonance

Rolf Gruetter, Hongxia Lei, Tian Cheng, Arnaud Comment, Josefina Adriana Maria Bastiaansen

BACKGROUND: The heart relies on continuous energy production and imbalances herein impair cardiac function directly. The tricarboxylic acid (TCA) cycle is the primary means of energy generation in the healthy myocardium, but direct noninvasive quantificati ...

Synthesis and Reactivity of Mononuclear Iron Models of [Fe]-Hydrogenase that Contain an Acylmethylpyridinol Ligand

Xile Hu, Dafa Chen, Bowen Hu

[Fe]-hydrogenase has a single iron-containing active site that features an acylmethylpyridinol ligand. This unique ligand environment had yet to be reproduced in synthetic models; however the synthesis and reactivity of a new class of small molecule mimics ...

New materials for methane capture from dilute and medium-concentration sources

Berend Smit

Methane (CH4) is an important greenhouse gas, second only to CO2, and is emitted into the atmosphere at different concentrations from a variety of sources. However, unlike CO2, which has a quadrupole moment and can be captured both physically and chemicall ...

Direct, in situ determination of pH and solute concentrations in formic acid dehydrogenation and CO2 hydrogenation in pressurised aqueous solutions using 1H and 13C NMR spectroscopy

Paul Joseph Dyson, Gabor Laurenczy, Séverine Joëlle Moret

In water, spin–lattice relaxation times (T1) and calibration curves for chemical shifts have been determined for the 13C and the 1H (C) atoms in HCOOH, HCOONa, CO2, Na2CO3 and NaHCO3 by NMR spectroscopy. These data facilitate kinetic and mechanistic studie ...

Control of morphology and nanostructure of copper and cobalt oxalates: Effect of complexing ions, polymeric additives and molecular weight

Heinrich Hofmann, Paul Bowen, Jacques Lemaître, Alke Fink, Nathalie Jongen

Precipitated oxalates are often nanostructured and can be used as precursors for nanostructured oxides for different applications. The modification of the particle shape and nanostructures of both copper and cobalt oxalates has been demonstrated using poly ...
