The research on energy storage devices such as lithium-ion batteries (LIBs) is vital for electric vehicles (EVs), electronic devices and grid-scale energy storage. According to...

Many of the devices currently used for energy storage (e.g., batteries, solar cells) use liquid electrolytes that are known to pose a serious fire and safety risk. In recent...

We propose a study to characterize diffusive motion of muonium, charge cycles and Mu0 states in vanadium dioxide (VO2) using zero and longitudinal field muon spin depolarization...

This proposal describes a muSR experiment on Li-deficient Lix(Ni1/3Co1/3Mn1/3)O2 to determine a Li diffusion coefficient as a function of the Li content x, because muSR is a...

The first experiment we propose is a search for a shallow-donor signal for muonium in indium oxide. Its observation would test our assertion, based on our measurements of...

The electronic dispersion of "Dirac" materials such as graphene and topological insulators is linear, resulting in a variety of peculiar electronic properties. In graphene and...

Proton-conducting polymer membranes have significant technological applications in hydrogen or methanol fuel cells. muSR can shed light on the mechanisms for proton transport in...

This proposal seeks to develop the technique of multinuclear RF decoupling and apply it to the study of lithium ion mobility in Lithium Hydroxide. Key to the understanding of...

In this experiment we propose to perform diffraction on isotopically substituted samples of Ca/Yb:ND/H3 and Ca/Yb:15ND3 at two concentrations (8 and 2 MPM) using the new NIMROD...

Recent advances in energy materials have led to the development of high capacity insertion cathodes for Li-ion batteries. One of the most promising of these materials is lithium...

Anion-exchange membranes are used in alkaline fuel cells, a technology which allows for the production of power from hydrogen in impure gas streams. Very little is known about...

Continued investigation of magnetic fluctuations in the Mn-doiped chalcopyrite semiconductor ZnGeP2 is proposed using LF-MuSR depolarization rates. Due to ferromagnetism above...

The origin of the Invar effect, whereby certain ferromagnetic alloys exhibit near zero thermal expansion around room temperature is still not properly understood. Although the...

lambda-(BETS)2GaCl4 is a non-magnetic anion-based organic superconductor SC attracting interest since its Fe analog becomes superconductor by applying 33 T. Both have similar Tc...

Skyrmions are chiral spin textures that exist in a variety of magnetic materials. These states are topologically non-trivial, which gives them stability expected to be useful...

Many of the devices currently used for energy storage (e.g., batteries, solar cells) use liquid electrolytes that are known to pose a serious fire and safety risk. In recent...

Ni-Mn based Heusler alloys with composition related to the stoichiometry Ni2MnX, with X belonging to the IIIA-VA chemical species, are widely considered as a class of...

Ni2Mn1+pZ1-p (Z= In, Sn, Sb and < p 1) based ferromagnetic shape memory alloys (FSMAs) with Heusler type structure are fascinating materials as far as the magneto-functional...

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...
