In the previous proposal we examined the ALC response of components of the complex dielectric under externally applied electric fields (EEF). We saw a shift in the asymmetry at...

We propose zero-field depolarization measurements to investigate the motional dynamics of diamagnetic muonium centers in hafnium oxide (HfO2), tungsten oxide (WO3) and zirconium...

Lead Halide perovskite solar cells are the next generation of solar cells, likely to over take silicon and organic solar cells in applications within the next 5-10 years. Lead...

Motivated by work showing that magnetic coupling between TCNQ anions in potassium TCNQ (KTCNQ) can be changed simply by changing the aromatic substituents, we seek to qunatify...

A continued study of muonium diffusion in transparent conducting oxides (TCO) are proposed. We have ZF depolarization measurements conducted up to room temperatures for SnO2 and...

This experiment is focused on exploring and harnessing magnetic ground state of the multiferroic materials, with particular emphasis on the hexagonal (h), rare-earth ferrites...

In order to meet the UK's commitment to reduce 80% of greenhouse gas emissions by 2050, it is necessary make major advances in efficient, clean and secure energy conversion and...

This is a continuation proposal describing an "in situ" muSR experiment on hydrogen storage materials. For the two previous beam-time allocated for RB1510262 and RB1520259, we...

We can trace the history of electrochemical cells just over two hundred years back to Luigi Galvani and Alessandro Volta¿s inventions, and perhaps more than a millennium further...

This proposal describes a muSR experiment for studying a diffusive nature of Li ions in novel anode material for Li-ion batteries. The target compound, LixY2Ti2O5S2 (LxYTOS,...

Lithium (Li) ion batteries is the most common battery technology but lately also sodium (Na) batteries are being considered. One reason is that the Li-reserves are limited and...

Lead Halide perovskite solar cells are the next generation of solar cells, likely to over take silicon and organic solar cells in applications within the next 5-10 years. Lead...

LiFePO4 is cathode material for Li ion batteries. One of the key functional properties is the Li-ion diffusion. Theoretical calculations showed that Li diffusion along the [010]...

The compounds belonging to the series of TMOs NaM2O4 (M = Ti, V, Mn, Cr) share the same interesting properties: they are all Q1D metallic antiferromagnets with the Na ions...

Whilst rechargeable batteries continue to take over the consumer electronics market, they are unsuitable to replace specific battery technologies, such as the thermal battery,...

This experiment proposes to measure the MuSR signal in undoped phthalocyanine (Pc) samples of NiPc, PbPc, FePc and TiOPc, in order to clarify the existence of the paramagnetic...

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

We ask for 3 days on EMU to study the Muon spectroscopy of both LiBH4 and Ca(BH4)2 as a function of temperature from 90K-650K. These materials have been extensively...

Amorphous molecular magnetic materials Ni2(OA) (OA:organic acceptor) were reported to exhibit ferromagnetism with Curie temperatures >400K. This work is controversial as it...

We found that muSR detects Li-diffusion in LixCoO2, LiNiO2, Lix(NiCoMn)O2 and LiFePO4 through a dynamic behavior of nuclear field relaxation. Very recently, we have also found...
