title: Impact of Protein Nanosheet Structure on Nanoscale Toughness

description: Cell adhesion and proliferation at the surface of liquids such as oil droplets is a surprising phenomenon as it is typically accepted in the field of bioengineering that cells require solid substrates to adhere and to exert mechanical forces. Our laboratory recently reported such observations and uncovered that such phenomenon was mediated by a nanoscale (15-20 nm) mechanically strong protein film (nanosheet) assembled at the liquid/liquid interface. We have also discovered that the molecular weight of surfactant (PLL) used strikingly influenced their mechanical behaviour: high molecular weight PLL form tougher nanosheets and sustain cell adhesion and expansion. This project aims to explore the structure of protein nanosheets assembled at analogous oil-water interfaces, in situ as a function of nanosheet molecular weight.

title: In-situ Study of Lithium Metal Penetration in Solid State Inorganic Electrolytes

description: All-solid-state Li-metal batteries aim for higher energy density and better safety than conventional Li-ion batteries due to their inflammable inorganic electrolytes and lithium metal electrode. The solid electrolytes are also believed to suppress Li-dendrite formation, which causes failure in organic liquid electrolytes. However, mechanical fracture and structural disintegration of the solid electrolytes can still occur during operation, leading to poor charge/discharge cyclic performance and increased likelihood of internal short circuits. Our research aims to understand how lithium metal penetration occurs. We will use neutron tomography, which is much more sensitive to lithium than X-ray tomography, to obtain the first observations of the progressive degradation of an all-solid-state Li-metal battery, by studying the spatial distribution of lithium.

title: Investigation of the magnetic correlations of MnSi in 3D

description: The recent discovery of skyrmions and skyrmion lattices in materials with no inversion symmetry and their corresponding potential applications of Skyrmions in magnetic information storage and processing devices has increased the scientific interest in these chiral materials. The archetype chiral system is MnSi, on which various studies have been performed. Recent findings point out to new mechanisms for stabilising new chiral magnetic phases and skyrmion correlations at low temperatures. In order to test the validity of these predictions we propose to map the magnetic correlations of MnSi in 3D by using the unique capabilities of the 3D magnetic field cryomagnet of ISIS.

title: Studying the vibrational dynamics of glycerol confined in graphene oxide membrane

description: Atomic vibrations play a vital role in the functions of various physical, chemical, and biological materials. The vibrational properties and the specific heat of a bulk material are well described by the Debye theory, which predicts the quadratic w^2 low-frequency scaling of the vibrational density of states (VDOS) in bulk solids from few fundamental assumptions. However, the corresponding relationships for nanoconfined materials with fewer degrees of freedom, have been far less well explored. A direct consequence of non-Debye scaling law is a shift of the acoustic modes towards a different frequency. Learning how graphene oxide membrane (GOM) modifies the vibrational dynamics of glass formers, is of utmost significance to understand and optimize the phonon-assisted transportation of energy, electron or proton in electronic devices and biological systems of nano-meter confinement.

title: Does sulphur dioxide react with atmospheric particulate at cloud water-air boundary

description: The atmospheric sulfur cycle is responsible for new particle formation and cloud condensation nuclei in the lower atmosphere. The proposal seeks to investigate if the unknown source of organo-sulfate compounds found in atmospheric aerosol is due to the reaction between gas-phase SO2 and natural surfactants found in cloud water and atmospheric aerosol at the air-water interface. The experiment will elucidate or exclude the surface reaction as a source of organic sulfate compounds in the atmosphere by measurement of kinetics and comparison to atmospheric removal processes. Real samples of atmospheric surfactants extracted from the atmosphere will be under study. The work supports a NERC grant between ISIS/RHUL and a new joint funded ISIS/RHUL PhD studentship.

title: In-Situ Ferromagnetic Resonance \2013 Polarised Neutron Reflectivity

description: Here, we aim to test a new beam capability: in-situ ferromagnetic resonance (FMR) with polarised neutron reflectivity (PNR). When placed in an external magnetic field, the magnetisation of a ferromagnetic material will precess about the external field in what is known as Larmor precession. If an alternating RF field is applied perpendicular to the external field at the Larmor precession frequency, there is a maximum in the absorbance and the cone angle of precession increases. Understanding magnetisation dynamics and FMR is key to many spintronics and magnonics applications as it determines e.g. the speed and energy cost of switching the magnetisation. FMR is also used in the transmission of angular momentum to non-magnetic layers for the generation and propagation of dissipationless spin currents and in the spin ↔ voltage conversion via the (inverse) spin Hall effect.

title: Deconfined spin excitation and universal scaling law of the field-induced spin liquid in the S=1/2 honeycomb antiferromagnet

description: Quantum spin liquid state is a novel state of matter beyond the classical description of magnetism in condensed matter physics. Owing to its significance in quantum computing and other novel applications, the quantum spin liquid is an important research subject. In the last decade, this topic has regained considerable popularity with the availabilities of new candidate materials. Kitaev quantum spin liquid is one branch of this large field that is a contemporary research topic with an advantage to solve the ground state analytically. This project proposes single-crystal inelastic neutron scattering on a new honeycomb-based Kitaev material to investigate the novel field-induced quantum spin liquid state. Our study will provide invaluable information in understanding the deconfined magnetic continuum in the context of quantum criticality.

title: Effect of phospholipid tail length and saturation on the spontaneous vesicle formation in the presence of amphiphilic drugs

description: Biological membranes and their interactions are naturally of the utmost importance for all living entities. Amphiphilic drugs interact and self-assemble with phospholipids and are expected to influence properties related to pharmacological activity and toxicity. For instance, they are expected to play a crucial role regarding specific interactions with receptor proteins, hemolytic degradation, as well as function as a drug delivery agent in release mechanisms and transport of drug molecules across cell membranes. The main purpose of the experiment is to determine the influence of the phospholipid tail length on the spontaneous vesicle formation in presence of amphiphilic drugs. The other key objective is determining the distribution of the drug in spontaneously formed drug/phospholipid vesicles by means of employing hydrated as well as a deuterated phospholipid in a contrast match study.

title: Investigation of the magnetic structure of the one dimensional spin-1 chain: PbCd2Ni6Te3O18

description: Recently the one dimensional spin chain have attracted considerable interest in condensed matter. The antiferromagnetic Heisenberg spin chain with integer spin has a short-range magnetic order and an excitation energy gap, so-called Haldane gap. Recently, PbCd2Ni6Te3O18 has been reported having 1D spin chain of Ni2+ ions (S=1) along the c-axis in its hexagonal crystal structure. PbCd2Ni6Te3O18 exhibits a long range magnetic ordering at TN=25.7 K confirmed through the susceptibility and heat capacity. The susceptibility above TN exhibits a broad maximum at 40 K indicating a development of a short range correlations. As there are no reports on the magnetic structure of this compound, here we proposed to investigate its magnetic structure and short range magnetic correlations using WISH. We will prepare the sample using 114Cd isotope to reduce neutron absorption.

title: Details about the Formation and Structural Evolution of Complexes of Humic Acid with Oppositely Charged Polyelectrolytes

description: Removal of Natural Organic Matter, humic acid (HA) is the main component, is a central problem during production of drinking water, thereby a central question for mankind. For that purpose polycations are employed and this process has been studied intensely, however, little with respect to the detailed colloidal aspects of this problem. This complexation has been studied by us, and in addition to conventionally used PDADMAC we have recently developed modified cationic chitosan compounds which show promising results in HA removal. To gain deeper insight into the interactions we will do stopped-flow SANS experiments in which HA and polycation are rapidly mixed and structural evolution of the formed complexes is observed. By knowing the initial stages we expect to gain a much better understanding of this important process that allows to tailor complexing polycations in a systematic fashion.

title: Impact of Li and mechanics on polymer dynamics in perfluoropolyether based polymers

description: Lithium metal based batteries are next-generation energy storage devices. A major challenge to industrial application of these batteries is uneven Li deposition on anode which results in dendritic growth and poor coulombic efficiency (CE). We recently reported that perfluoropolyether polymer networks with evenly spaced H-bonding sites of various mechanical strengths are useful as coatings on Li anode surface and batteries prepared with coated polymers with a weaker mechanical strength (i.e. better flowability) exhibit higher CE. We now plan to probe the polymer dynamics using QENS experiment correlate that with the measured viscosity, mechanics and ionic conductivity at room temperature. We believe that this will help us to understand the charge transport mechanism in this new material.
