Comparison of Dynamical Behaviour in MAPbX3 and FAPbX3: How Do They Differ ?
Organic-inorganic lead halide perovskite compounds are shown to be very promising candidates for low cost, solution-processable, highly efficient (>22%) solar cells with a... -
Proposal to determine the origin of the effects of electric fields on the muo...
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... -
Measurement of spin-gravity coupling by quantum interference
It is possible that there is a coupling between the spin and gravitation, for instance by an adaptation of the Hamiltonian with an additional termH=k/c (gvec.Svec) where gvec is... -
Probing CoFeNi thin films using polarised neutrons
Near-equimolar multi-component alloys, known as high entropy alloys (HEAs), possess potential for the development of new functional micromaterials. HEAs can be stabilised by... -
Unstressed lattice parameter studies for weld residual stress determination
This study addresses the need to improve the reliability of measurements of weld residual stress; particularly for the type of welds used within the nuclear power industry. Such... -
Proton transfer in croconic acid
Croconic acid has recently emerged as the first example of an above room-temperature organic single component ferroelectric. Our goal is to determine its crystal structure at... -
Satisfying the need for contrast in antimicrobial research
Gram-negative bacteria, which cause a variety of diseases including meningitis, plague, sepsis and food poisoning, are becoming increasingly antibiotic resistant. One reason is... -
Crystal and magnetic structure of the polar ferrimagnet BaCaFe4O7
Polar or non-centrosymmetric ferri(-o)magnets offer a plethora of potential technological devices; the inherent magnetoelectric effect can underpin both pyroelectric or... -
Divacancy superstructures and enhanced thermopower in NaxCayCoO2
Replacing Na ions in NaxCoO2 with divalent Ca ions results in the formation of ordered arrays of divacancy clusters, rather than the trivacancy clusters found for the pure... -
MuSR study on optically injected electronic spin in GaAs
In the field of semiconductor spintronics, n-type GaAs has been utilized as a prototype system, where one can inject electronic spin and study its behavior with optical... -
Probing the meta-stable nature and time induced ferromagnetic phase growth in...
In recent years, the investigation of metamagnetic properties of first order magnetic systems has become revolutionary. The rare-earth based compound Nd5Ge3 exhibits a magnetic... -
Depth profiling fullerene-free organic solar cell blends using neutron reflec...
In Sheffield, 9% efficient organic solar cells have been made using a new non-fullerene acceptor called ITIC, when blended with semiconducting polymers. GIWAXS measurements have... -
Cold Sprayed Hydroxyapatite Coatings for Orthopaedic Implants
Hydroxyapatite (HA) is a natural compound (Ca10 (PO4)6(OH) 2) found in human bone and clinical research has shown that HA coated orthopaedic implants improve the ingrowth and... -
The phase diagram of the spin-density-wave metamagnet Sr3Ru2O7
Sr3Ru2O7 is an unusual layered oxide metamagnetic metal. It has been know for some time that the application of a large magnetic field (~8 T) perpendicular to the RuO2 planes... -
Understanding Sulphur and Nitrogen-Aromatic interactions from liquid structure
Asphaltenes are a complex and problematic fraction of crude oil that can precipitate, alter wettability and stabilise unwanted oil-in-water emulsions. Asphaltenes have a high... -
Low-dimensional glasses: Effect of occupational site disorder in the excess o...
The present scientific case concerns a glass-forming system with even less degrees of freedom, namely the occupational disorder of high-temperature phase (I, P21/c) of... -
Oxygen Vacancy Clusters in Pure and Doped CeO2-d
Oxide ceramics based on ceria, CeO2, have been the subject of considerable research for the role of solid electrolyte within solid oxide fuel cells (SOFCs), since their ionic... -
