Lithium-excess cathode materials can deliver high capacity and lead to high energy density. Lithium-excess cathode materials are categorized as “ordered” and “disordered” on the...

In order to improve the performance of future energy devices, nano-structuring materials is one of the most promising routes. LiFePO4 is a commercial battery cathode material...

Cubic cadmium(II) cyanide shows the most pronounced isotropic negative thermal expansion (NTE) effect known, with behaviour more than twice as extreme as that of better known...

NaxMO2 layered oxides are being investigated as potential cathodes for Na-ion batteries. These systems present a variety of structures that are classified in terms of the Na...

One of the technological goals is to create materials that show high permittivity and low dielectric loss, which has been achieved by the co-doping of Nb and In into rutile...

Spins arranged on the kagome lattice are one of the most widely investigated topics in frustrated magnetism. In this context, the three-dimensional analogue of these systems,...

The magnetic excitations will be studied in a powdered sample of 3% CoO in 97% MgO in order to to study the excitations of isolated Co ions and of isolated pairs of Co ions....

We have prepared a new family of electron-doped oxypnictides \RFeF\ with the same average Rare Earth radius as that yielding the highest superconducting Tc to date, i.e. the...

Experiment is proposed to identify magnetic polaron bound to the muon using RF-muSR. In recent experiment at TRIUMF magnetic polaron was found in transverse field and its...

When we know an intrinsic diffusion coefficient of Li-ion (D) in an ionic conductor, we could estimate a number of mobile Li ions, i.e. carrier density (n), from ionic...

We propose longitudinal muon spin depolarization measurements to extract the energy for the T-site Mu acceptor level in mid-range SiGe alloys where a direct determination of the...

Previous muon experiments have identified a muonium state in the commonly occuring, but complex, beta rhombohedral form of elemental boron. To complement recent theoretical work...

We wish to complete muon spectroscopic experiments on materials from a ceramic system of interest for possible solid electrolyte applications in lithium-ion battery devices:...

LiFePO4 (LFP) is a commercially applied cathode material for lithium ion batteries. With its Li ion hopping predominantly occurring along one-dimensional channels, LFP is a very...

This experiment will probe the evolution of magnetic ordering in compounds with square planar Cr2+ ions in CrO2 oxide layers, and the interaction of these moments with Mn2+ and...

The solid state of L-alpha-alanine is routinely used as a dosimeter for X-ray, gamma, and electron radiations. Recently, in the framework of boron neutron capture therapy, it...

In order to estimate a reliable reaction area (a_r) between cathode and liquid electrolyte in a Li-ion battery, we wish to propose a muSR experiment on a charged-state cathode...

This proposal describes a continuation muSR experiment on Li-Mn-oxides to see Li diffusion, because muSR is a powerful technique to detect it in the compounds containing...

Following our μSR experiment on liquid water (RB1720491) we propose to measure molecular diffusion coefficient (the sum of the diffusion coefficients of muonium and oxygen...

Research on positive insertion electrodes for high performance batteries has seen immense interest in fluoride containing compounds, since higher operating potentials can be...
