High-throughput techniques for the cha racterisation of biological structures are providing large amounts of info rmation over length scales from atomic through to cellular and tissue leve ls of organization. There is now increasing emphasis on interdisciplinary and multi-technique approaches\, and centres for integrated structural bio logy are being created and developed throughout the world\, notably at loc ations that host large facilities such as synchrotron radiation and neutro n beam sources\, and cryo-electron microscopy. This progress\, and the sci entific yields arising\, is driven by continuous technical development at the large facilities themselves\, as well as through developments in assoc iated methodologies for sample production and characterization. These\, as well as broader infrastructural development\, including engagement with t he user communities\, and crucially\, training\, will be of huge importanc e in narrowing the gap between the current state-of-the-art for structural biology and fundamental knowledge in the life sciences and applications i n medicine. \nA summary of this context will be given along with illustrat ive examples over a range of biological/biomedical science.\n\nhttps://lin dico453.srv.lu.se/event/214/contributions/1045/ LOCATION: URL:https://lindico453.srv.lu.se/event/214/contributions/1045/ END:VEVENT BEGIN:VEVENT SUMMARY:SNSS Seminar Series: Neutron Diffraction\, Speaker 2 - Non-equilib rium phases and cation mixing in Li-rich rock salt derived positive electr ode materials DTSTART;VALUE=DATE-TIME:20210511T113000Z DTEND;VALUE=DATE-TIME:20210511T120000Z DTSTAMP;VALUE=DATE-TIME:20260528T071251Z UID:indico-contribution-214-1074@lindico453.srv.lu.se DESCRIPTION:Speakers: William Brant (Uppsala University)\nOften within the domain of inorganic chemistry synthesis\, focus is placed on obtaining id eal materials under equilibrium conditions in order to accurately study sp ecific phenomena. However\, while extremely valuable\, these studies often do not represent the real structures which are formed when materials are utilized in an application or a device. This is particularly true in the c ase of electrode materials for rechargeable ion batteries where it is noto riously difficult to predict what phases are formed as electrochemical ext raction of charged ions proceeds far from the thermodynamically stable con figuration of a material. In this contribution I will present results from two different Li-rich rock salt derived oxide systems\, Li1+xTM1-xO2 (0 ≤ x ≤ ⅓\, TM= Mn\, Ni and Co) and Li2VO2F. Both compounds do not exh ibit ideal structures and the properties are intricately tied to the local cation configurations generated via non-equilibrium phase transitions.\nT he structure of lithium rich layered phases\, Li1+xTM1-xO2\, is complicate d by disorder which manifests over multiple length scales. At the atomic s cale Li and TM cations can order forming a superstructure\, this superstru cture allows for the appearance of stacking faults which extends beyond th e unit cell. Finally\, phase segregation of different ordered domains can occur on the nano to micron length scale. The disorder present can vary si gnificantly even for a single composition depending upon the specific synt hesis conditions. These multiple metastable phases which exhibit near iden tical average structures has confounded research into these materials\, hi ndering an understanding of their anionic redox properties.\nLi2VO2F is a metastable disordered rock salt structure which shows promise as a high ca pacity cathode material. However\, significant capacity fade during electr ochemical cycling impedes its implementation. Understanding the origin of the capacity fade is challenging due to the reconstructive phase transitio n that occurs upon lithium extraction. One might expect that over time the structure converts to more thermodynamically stable structures that are l ess electrochemically active. However\, using a combination of X-ray and n eutron diffraction\, we demonstrate that this is not the case and that oth er crystalline metastable phases stabilise and grow over successive electr ochemical cycles.\n\nhttps://lindico453.srv.lu.se/event/214/contributions/ 1074/ LOCATION: URL:https://lindico453.srv.lu.se/event/214/contributions/1074/ END:VEVENT BEGIN:VEVENT SUMMARY:Neutron research\, Contr. talk 4 - Detection of water in cement mo rtar at room temperature and during freezing DTSTART;VALUE=DATE-TIME:20210510T130000Z DTEND;VALUE=DATE-TIME:20210510T132000Z DTSTAMP;VALUE=DATE-TIME:20260528T071251Z UID:indico-contribution-214-1070@lindico453.srv.lu.se DESCRIPTION:Speakers: Katja Frid (Malmö University)\nWater is present in most of the degradation mechanisms that concrete is exposed to. When these mechanisms are studied experimentally to build models\, it is very import ant that the moisture content in the material is controlled and correct. T he aim for the experiment was to study the water and pore distribution in air-entrained cement mortar with varying moisture preconditioning using du al-modality neutron and x-ray tomography. Furthermore\, in-situ freeze-tha w cycling of cement mortar was performed to visualize the evolution of the water distribution in the pores.\nThe test was divided into two parts. In the first part different moisture pre- conditionings was studied in four samples : (1) Dried at 40C\, (2) Capillary saturated\,\n(3) cured moist ure sealed (4) Vacuum saturated. The samples had a diameter of 10 mm and a height of 10 mm and were moisture sealed during the measurements. A voxel size of 7 μm was used for the neutron imaging and 19.5 μm for the x-ray imaging. Analysis found that it was possible to detect water in the large r pores. It was also found that even after vacuum saturation not all pores were filled.\n\nIn part two\, an in-house built freezing device was used to study the evolving water distribution during freeze-thaw cycling. The d evice was based upon a Peltier element and circulation of a cooling fluid to reach temperatures well below 0C. A vacuum saturated cement mortar s ample (outer diameter 10 mm\, height 10 mm) with water on the top surface was subjected to three freeze-thaw cycles. The sample was imaged at each f rozen/thawed state but due to time limitations\, a full dual-modality data set was only acquired before and at the first freezing as well as at and a fter the third freezing (in total four complete data sets). During the fre ezing\, the temperature was lowered to approximately -13C measured in t he sample and held constant during the imaging. A voxel size of 7 μm was used for the neutron imaging and 19.5 μm for the x-ray imaging.\n\nThe pr eliminary analysis of the sample during freeze-thaw cycling shows some sma ll changes in greyscale value in the cement matrix during temperature cycl ing which can be used to understand the filling of the pore structure due to freezing/thawing. We also found and small changes in relative water con tent of partially filled air voids. This can be used to understand the pro tective role of air voids.\nThis technique is very promising for further v erification of different parts of the mechanism of frost deterioration in concrete. Something that the frost community has longed for!\n\nhttps://li ndico453.srv.lu.se/event/214/contributions/1070/ LOCATION: URL:https://lindico453.srv.lu.se/event/214/contributions/1070/ END:VEVENT BEGIN:VEVENT SUMMARY:Neutron research\, Contr. talk 2 - Sucrose versus trehalose as pos sible preservatives for proteins DTSTART;VALUE=DATE-TIME:20210510T122000Z DTEND;VALUE=DATE-TIME:20210510T124000Z DTSTAMP;VALUE=DATE-TIME:20260528T071251Z UID:indico-contribution-214-1068@lindico453.srv.lu.se DESCRIPTION:Speakers: Inna Ermilova ()\nSucrose and trehalose are well-kno wn industrial preservatives for various purposes: they are widely used in cosmetics\, food conservation and pharmaceutical industry [1\,2]. For inst ance\, sucrose is a stabilizing compound of covid-19 vaccine produced by P fizer [3]. In this work with the help of atomistic molecular dynamics simu lations sucrose and trehalose were considered as agents for preservation o f two model-proteins (myoglobin and Aβ(1-42) peptide) at three different water contents. Results of calculations of self-intermediate scattering fu nctions demonstrated that systems containing sugars with the smaller amoun t of water needed more than 100 ns\, while similar systems without sugars could be relaxed in at around 60-80 ns. Trehalose was the best stabilizing agent in all studied cases which could be a consequence of a slower dynam ics of this sugar.\n\n[1] Olsson\, Christoffer\, Samuel Genheden\, Victori a García Sakai\, and Jan Swenson.

They ar e known to have a detrimental effect on mechanical properties and can even cause SLM process failure. Therefore\, it is always needing to be applied additional heat treatment operations to relieve stress or shock peening t o convert the tensile stress to the compressive stresses. Without the know ledge of residual stress in the material\, it is not possible to estimate the service life or ensure the integrity of machine parts. Among various e xperimental techniques\, only neutron and high-energy synchrotron X-ray te chniques allow us to accurately measure the deep internal stress in large metallic samples with all stress components nondestructively. In this talk \, we will discuss how neutron techniques are important for additive manuf acturing or metallic materials research in general and present some of our residual stress characterization work performed on SLM build stainless st eel which utilized both standard neutron diffraction and neutron Bragg edg e imaging to investigate the effect of Hot Isostatic Pressing (HIP) temper ature and heat treatment to the residual stress.\n\nAcknowledgment: The pr oject is funded by Vinnova (2019-05304).\n\nhttps://lindico453.srv.lu.se/e vent/214/contributions/1067/ LOCATION: URL:https://lindico453.srv.lu.se/event/214/contributions/1067/ END:VEVENT BEGIN:VEVENT SUMMARY:SNSS Seminar Series: Neutron Diffraction\, Speaker 4 - Additive ma nufacturing and neutron diffraction: Residual stress assessment and contro l DTSTART;VALUE=DATE-TIME:20210511T123000Z DTEND;VALUE=DATE-TIME:20210511T130000Z DTSTAMP;VALUE=DATE-TIME:20260528T071251Z UID:indico-contribution-214-1076@lindico453.srv.lu.se DESCRIPTION:Speakers: Prabhat Pant (Linköping University)\nAdditive manuf acturing (AM) of components made out of metals using powder and laser has been in increasing demand especially in the sector of aerospace\, medical sectors\, etc. With AM\, parts with complex geometries can be manufactured easily in comparison to the traditional ones. However\, with the ease of\ nmanufacturing complex parts\, several issues must be tackled to get a goo d quality party without losing its mechanical integrity. One of such issue s is the control of residual stresses (RS). These RS are generated mainly due to the temperature difference between the consecutive layers while pri nting. For a comprehensive and systematic study of different process param eters such as print orientations and scan strategies two separate studies on L-shaped geometry printed out of IN718 superalloy were done. The first study was on print orientation\nwhere parts were printed in different orie ntations namely: horizontal (HB)\, vertical (VB)\, and 45° angle (45B)\, and for the second study parts were printed in the vertical orientation wi th different scan strategies. With the help of neutron diffraction\, RS di stribution in the bulk of the sample and the influence of these printing p arameters on the RS magnitude and distribution were studied. For the print orientation study\, it was found that\npart built in a Vertical orientati on has the highest magnitude of RS and for the scan strategies' influence\ , it was found that different scan strategies can lead to the reduction of RS in the same part printed in the vertical orientation. From the data av ailable from the experiment\, a simplified FEM model to predict the RS due to print orientation was also established. The model can predict the RS d istribution trend similar to that measured ones but with a higher magnitud e of stresses. Further data from the neutron diffraction results can be us ed to calibrate the existing models for the prediction of RS in AM or to v erify new models as well.\n\nhttps://lindico453.srv.lu.se/event/214/contri butions/1076/ LOCATION: URL:https://lindico453.srv.lu.se/event/214/contributions/1076/ END:VEVENT BEGIN:VEVENT SUMMARY:SNSS Seminar Series: Neutron Diffraction\, Speaker 3 - Magnetic di ffraction: Exploring hidden magnetic symmetries DTSTART;VALUE=DATE-TIME:20210511T120000Z DTEND;VALUE=DATE-TIME:20210511T123000Z DTSTAMP;VALUE=DATE-TIME:20260528T071251Z UID:indico-contribution-214-1075@lindico453.srv.lu.se DESCRIPTION:Speakers: Johan Cedervall (Stockholm University)\nMagnetic mat erials are found everywhere and in all sorts of applications in the societ y today and new applications are constantly being developed. Some examples are generators in\nwindmills and electrical motors and magnetic cooling. In addition\, to effectively operate a generator\, it requires several typ es of specialised magnetic materials. To understand materials\nmagnetic be haviour\, good knowledge of its structure is required\, something that dif fraction methods can provide. Neutrons weak interaction with matter\, give n their uncharged state\, makes them interact with the nuclei and in a non -magnetised material\, the nuclear structure can be explored. However\, gi ven that neutrons also carries a magnetic moment\, they will interact with unpaired electrons in a material\, giving an additional scattering featur e\, i.e. magnetic scattering. In the non-magnetised paramagnetic state\, t his additional scattering will be diffuse\, whereas in a magnetised state sharp Bragg peaks will occur.\nIn this talk\, I will explore a variety of magnetic materials with different magnetic interactions and guide you thro ugh how the magnetic structures where resolved. To do so\, the basics of\n magnetic symmetries and their relation to conventional symmetries and spac e groups will be covered.

The size and shape of cationic micelles can be controlled via their interaction with their soluble count er-anions\, and this is well known to affect properties such as the critic al micelle concentration. However\, although the bulk properties of such s olutions have been studied using a range of techniques including conductiv ity and small angle scattering\, it is difficult to directly measure the i nteractions between the surfactant headgroups and ions in solution. Much o f the literature description of these systems is therefore inferred from t hese bulk measurements. We have used wide angle neutron scattering on solu tions of decyltrimethylammonium cations\, which have been ion exchanged to contain a range of counteranions\, along the Hofmeister series\, to direc tly probe interactions in these systems. The data was modelled using Empir ical Potential Structure Refinement (EPSR) to study the association betwee n the different counterions and the micelle surfaces and how this affects micellar structures in these systems.\n\nhttps://lindico453.srv.lu.se/even t/214/contributions/1073/ LOCATION: URL:https://lindico453.srv.lu.se/event/214/contributions/1073/ END:VEVENT BEGIN:VEVENT SUMMARY:SWEDNESS session: Presentation of the new SwedNess-II research pro jects DTSTART;VALUE=DATE-TIME:20210511T135000Z DTEND;VALUE=DATE-TIME:20210511T150000Z DTSTAMP;VALUE=DATE-TIME:20260528T071251Z UID:indico-contribution-214-1072@lindico453.srv.lu.se DESCRIPTION:https://lindico453.srv.lu.se/event/214/contributions/1072/ LOCATION: URL:https://lindico453.srv.lu.se/event/214/contributions/1072/ END:VEVENT BEGIN:VEVENT SUMMARY:Neutron research\, Contr. talk 5 - The solution structure of the p entameric ligand-gated ion channel GLIC probed by small-angle neutron scat tering DTSTART;VALUE=DATE-TIME:20210510T132000Z DTEND;VALUE=DATE-TIME:20210510T134000Z DTSTAMP;VALUE=DATE-TIME:20260528T071251Z UID:indico-contribution-214-1071@lindico453.srv.lu.se DESCRIPTION:Speakers: Marie Lycksell (Stockholm University)\nPentameric li gand-gated ion channels undergo subtle conformational cycling to control e lectrochemical signal transduction in many kingdoms of life.

Data col lection was optimized by inline paused-flow size-exclusion chromatography\ , and exchanging into deuterated detergent to hide the micelle contributio n. Resting-state GLIC was the best-fit crystal structure to SANS curves\, with no evidence for divergent mechanisms.

Moreover\, the combination of\ndiffere nt precursors provides a certain control over the physicochemical properti es of the\nsolvent (e.g. solvent polarity and charge density). Thus\, DES are regarded as task-specific\n“cocktails”\, where the properties of t he solvent can be tuned to suit particular applications.\nRecent developme nts have shown the ability of DES to support amphiphile self-assembly\,\nb ringing the possibility to develop sustainable alternatives for surfactant templating\, drug\ndelivery and biosensing\, among others.
