Nano‐Octahedron Cobalt Oxide Decorated Graphene Nanocomposites for the Selective/Simultaneous Detection of Dopamine

Advanced Materials Interfaces, EarlyView.
Nano‐octahedron Co3O4 decorated graphene composite electrode for selective and simultaneous detection of dopamine. The detection limit of 0.09 µM, and linear range from 1 to 500 µM are reported. The synergistic effect of nano octahedron Co3O4 and graphene results in excellent performance of the sensor in terms of selectivity and sensitivity.

Understanding the Role of Copper Oxidation State on a TiO2/ZSM‐5 Catalyst for Photocatalytic CO2 Reduction to Methanol

Advanced Materials Interfaces, EarlyView.
The influence of copper oxidation states on TiO₂/ZSM‐5 catalysts is investigated for photocatalytic CO2 reduction to methanol. A Cuδ⁺‐modified Ti₂/ZSM‐5 catalyst (CTZ‐1) exhibits superior activity due to enhanced electronhole separation, the presence of Ti3⁺, and a core–shell structure.

Tailoring the Solid Electrolyte Interphase Composition on Lithium Metal Anodes by the Choice of Ionic Liquid during Mechanochemical Modification

Advanced Materials Interfaces, EarlyView.
Roll‐pressing lithium foil in contact with ionic liquids is used to produce modified lithium anodes. The differences in performance, composition, and evolution upon cycling of the anodes depending on the ionic liquid used are highlighted, when used in combination with a classical Li‐ion electrolyte.

Carbonization Tuned Core‐Shell Fe3O4@C Nanostructures with Enhanced Electromagnetic Wave Absorption

Advanced Materials Interfaces, EarlyView.
The core‐shell structured Fe3O4@C composites are prepared by employing an in situ polymerization and carbonization treatment method. The effect of carbonization temperature on electromagnetic wave absorption of H‐FO@C composites is symmetrically analyzed, and the impedance matching and attenuation ability are improved significantly by controlling ...

Nuclear magnetic resonance spectroscopy [PDF]

Resonance, 2004
Nuclear magnetic resonance in condensed matter was discovered simultaneously by Edward Purcell at Harvard and Felix Bloch at Stanford in 1946 using different instrumentation and techniques. Both groups observed the response of magnetic nuclei, placed in a uniform magnetic field, to a continuous radio frequency magnetic field as the field was tuned ...

Nuclear magnetic resonance spectroscopy

1972
The first observations of the nuclear magnetic resonance (NMR) phenomena were reported in 1946 by Purcell [1] at Harvard University and by Bloch [2] at Stanford University. Since that time, NMR spectroscopy has experienced a remarkable growth and is presently one of the most useful instrumental techniques for the Study of chemical systems.
