description: With backing from national health authorities, large-scale electronic health record (EHR) suites have increasingly entered the European healthcare market. The overall goal for these systems is to fulfill the needs of healthcare workers in hospitals, nursing homes, home-care service, and general practitioner (GP) clinics. The EHR suites will replace existing EHRs in their targeted area. However, the national and regional authorities cannot mandate that municipalities and GPs implement these new EHR systems. Therefore, there will still be ways for the suppliers of existing systems to compete for market share and provide municipalities and GPs with viable alternatives. We explore these issues by focusing on how suppliers of the EHRs currently used by municipalities maneuver under the imminent threat from an EHR suite. Empirically, we focus on the three principal suppliers of EHR systems to the Norwegian municipal healthcare market. They are facing the introduction of a large-scale EHR suite in Central Norway in 2022 combined with the long-term national ambition of a common EHR system for the rest of the municipal health sector in Norway. Conceptually, we draw on information infrastructure literature.

description: The current era of global uncertainty has strained the relationships of many formerly reliable partners. Although the Canada-U.K. relationship has been the exception, both countries are going through rough patches with other major partners – targeted by American tariffs, Canada was forced to play defence during aggressive NAFTA renegotiations. The United Kingdom is attempting to divorce its largest trading partner, the European Union. These issues have fostered conditions for the U.K. and Canada to become even stronger partners. Now is the time for our countries to capitalize on our longstanding relationship while also looking outwards for new opportunities.

description: We have considered a model of two component mixture i.e., mixture of Chaplygin gas and barotropic fluid with tachyonic field. In the case, when they have no interaction then both of them retain their own properties. Let us consider an energy flow between barotropic and tachyonic fluids. In both the cases we find the exact solutions for the tachyonic field and the tachyonic potential and show that the tachyonic potential follows the asymptotic behavior. We have considered an interaction between these two fluids by introducing a coupling term. Finally, we have considered a model of three component mixture i.e., mixture of tachyonic field, Chaplygin gas and barotropic fluid with or without interaction. The coupling functions decays with time indicating a strong energy flow at the initial period and weak stable interaction at later stage. To keep the observational support of recent acceleration we have considered two particular forms (i) Logamediate Scenario and (ii) Intermediate Scenario, of evolution of the Universe. We have examined the natures of the recent developed statefinder parameters and slow-roll parameters in both scenarios with and without interactions in whole evolution of the universe.

description: Q Cygni (Nova Cygni 1876) is the third oldest old novae (after WY Sge and V841 Oph) with a long orbital period of 10.08 hours and spectroscopic peculiarities in the optical including the presence of variable wind outflow revealed by optical P Cygni profiles in the HeI lines and H alpha beta (Kafka et al. 2003). We have carried out a synthetic spectral analysis of a far ultraviolet IUE archival spectrum of Q Cygni using our optically thick, steady state, accretion disk models and model white dwarf photospheres. We find that the accretion light of a luminous accretion disk dominates the FUV flux of the hot component with a rate of accretion 2-3 1.E-9 Msun/yr. We find that Q Cygni lies at a distance of 741 \pm 110 pc . The implications of our results for theoretical predictions for old novae are presented.

description: We present discovery observations of a quasar in the Canada-France High-z Quasar Survey (CFHQS) at redshift z=6.44. We also use near-IR spectroscopy of nine CFHQS quasars at z~6 to determine black hole masses. These are compared with similar estimates for more luminous Sloan Digital Sky Survey (SDSS) quasars to investigate the relationship between black hole mass and quasar luminosity. We find a strong correlation between MgII FWHM and UV luminosity and that most quasars at this early epoch are accreting close to the Eddington limit. Thus these quasars appear to be in an early stage of their life cycle where they are building up their black hole mass exponentially. Combining these results with the quasar luminosity function, we derive the black hole mass function at z=6. Our black hole mass function is ~10^4 times lower than at z=0 and substantially below estimates from previous studies. The main uncertainties which could increase the black hole mass function are a larger population of obscured quasars at high-redshift than is observed at low-redshift and/or a low quasar duty cycle at z=6. In comparison, the global stellar mass function is only ~10^2 times lower at z=6 than at z=0. The difference between the black hole and stellar mass function evolution is due to either rapid early star formation which is not limited by radiation pressure as is the case for black hole growth or inefficient black hole seeding. Our work predicts that the black hole mass - stellar mass relation for a volume-limited sample of galaxies declines rapidly at very high redshift. This is in contrast to the observed increase at 4

description: This paper conducts an empirically study on the trade package composed of a sequence of consecutive purchases or sales of 23 stocks in Chinese stock market. We investigate the probability distributions of the execution time, the number of trades and the total trading volume of trade packages, and analyze the possible scaling relations between them. Quantitative differences are observed between the institutional and individual investors. The trading profile of trade packages is investigated to reveal the preference of large trades on trading volumes and transaction time of the day, and the different profiles of two types of investors imply that institutions may be more informed than individuals. We further analyze the price impacts of both the entire trade packages and the individual transactions inside trade packages. We find the price impact of trade packages is nonnegligible over the period of the execution time and it may have a power-law relation with the total trading volume. The price impact of the transactions inside trade packages displays a U-shaped profile with respect to the time $t$ of the day, and also shows a power-law dependence on their trading volumes. The trading volumes of the transactions inside trade packages made by institutions have a stronger impact on current returns, but the following price reversals persist over a relatively shorter horizon in comparison with those by individuals.

description: When x-rays penetrate soft matter, their phase changes more rapidly than their amplitude. In- terference effects visible with high brightness sources creates higher contrast, edge enhanced images. When the object is piecewise smooth (made of big blocks of a few components), such higher con- trast datasets have a sparse solution. We apply basis pursuit solvers to improve SNR, remove ring artifacts, reduce the number of views and radiation dose from phase contrast datasets collected at the Hard X-Ray Micro Tomography Beamline at the Advanced Light Source. We report a GPU code for the most computationally intensive task, the gridding and inverse gridding algorithm (non uniform sampled Fourier transform).

description: Shared information infrastructures are required for personal health data to be shared along patient trajectories. Building such data sharing infrastructures will involve multiple stakeholders, which can be expected to share some common goals, but also to have divergent interests and priorities. Thus, collective action dilemmas easily emerge and may prevent progress. In the paper we wish to investigate how social structures influence the emergence (or avoidance) of collective action dilemmas. We have conducted a retrospective, qualitative analysis of the establishment of the Great North Care Record in the UK, focusing on the approach to mobilize and organize the participants. We find that pre-existing, multi-organisational peer networks, forums and relationships were in place and were actively used as social modules for mobilization. These networks and forums allowed spaces and occasions for interactions, observations and negotiations that were necessary to avoid and resolve collective action dilemmas. Thus, these networks and forums provided a core “social installed base” on which to build. These networks had been ‘organically’ emerging along the patient flow patterns. They followed the “Goldilocks principle” (‘just right’) – small enough to allow the avoidance or resolution of collective action dilemmas, and large enough that benefits would accrue from the cooperation.

description: Demographic transformation and medical-technical progress are generating new demands for standards and quality in professional caregiving. The job profile and especially the nature of care apprenticeships is changing significantly and use of digital media is becoming an increasingly ubiquitous and important aspect of the work. In this paper, we present a design case study that focuses on the development and evaluation of a multimedia learning application for and with care students. Adopting a user-centered design approach, we collected design requirements for the application in workshops and interviews with 23 care-students. The results show that it is important to create a structured approach to providing information and that social aspects such as chat allow for higher motivation and collaboration in learning. The findings also suggest that, by using game mechanisms such as a quizzes and difficulty levels, care-students can be further motivated to become more engaged with learning content.

description: In a zero-dimensional superconductor, quantum size effects(QSE) not only set the limit to superconductivity, but are also at the heart of new phenomena such as shell effects, which have been predicted to result in large enhancements of the superconducting energy gap. Here, we experimentally demonstrate these QSE through measurements on single, isolated Pb and Sn nanoparticles. In both systems superconductivity is ultimately quenched at sizes governed by the dominance of the quantum fluctuations of the order parameter. However, before the destruction of superconductivity, in Sn nanoparticles we observe giant oscillations in the superconducting energy gap with particle size leading to enhancements as large as 60%. These oscillations are the first experimental proof of coherent shell effects in nanoscale superconductors. Contrarily, we observe no such oscillations in the gap for Pb nanoparticles, which is ascribed to the suppression of shell effects for shorter coherence lengths. Our study paves the way to exploit QSE in boosting superconductivity in low-dimensional systems.

description: In recent years, both the public and private sector organizations have started shifting to large-scale information systems (IS). Still, the results of these large-scale implementations are not very promising. Ensuring user participation is considered as a (partial) solution to overcome the issues associated with large-scale IS development. Given the complexities associated with the scale, the activities happening in large-scale projects are categorized as front-stage and back-stage, and it is essential to engage users in both of these activities. The literature around the component of user participation in back-stage of large-scale projects is not very mature. We contribute to this by studying a large-scale medical record system implementation in central Norway. Our findings highlight that the back-stage activities are very prevalent in large-scale projects whereas these activities lack adequate user participation.

description: The Covid-19 pandemic has forced hospitals to adapt and rethink how they treat patients to limit the spread of the virus and avoid overloading during spikes of admission. Danish hospitals have implemented video consultations which enable patients and clinicians to see and talk to each other without the patients coming to the hospital. Based on observations of clinicians’ video consultations with patients, as well as observations of online hospital meetings regarding virtual outpatient clinics, this paper explores clinicians’ experiences with adopting video consultations. The paper unfolds what this new form of consultation repairs, leaves behind, and engenders. Finally, the paper speculates about how the digital transformation might anchor itself in the healthcare sector, also in a post-pandemic future.

description: In this paper, we investigate a newly established Business Intelligence unit providing healthcare data and analyses for management and staff at five hospitals in the Region. Created in 2015, the Business Intelligence Unit repurposes data generated by digital healthcare systems and aims to “[...] support the Region [...] in delivering more welfare, better quality, higher impact, and greater sustainability for less money.” Within healthcare – and in other domains – there is a strong push towards becoming (more) data- driven and repurpose data to increase efficiency, quality, and cost-effectiveness. However, whereas there are numerous publications on ‘datafication’ in the abstract, there is a dearth of studies on how the data at the center of such processes is actually produced, and even fewer studies on the people and organizational units engaged in this work. Hence, we are engaged in an ethnographic study on data work at the Business Intelligence Unit in order to gain insights into the work and practices of generating healthcare data for secondary use. In this paper, we present the preliminary findings focusing on three themes: end-user engagement, creating meaningful data reports, and establishing trust. One overall contribution is that whereas Business Intelligence work does require technical competences to work with large-volume data, it also requires competences of engaging with healthcare staff and understanding their work practices.

description: In this paper we draw attention to the duality of mental health assessment in a refugee camp: its sensing and numeration by Medical Assistants providing door-step services to the refugees. Drawing on ethnographic fieldwork in Kutapalong, Bangladesh, we explore the moods that pervade the refuges and their dwellings as these moods are important to the Medical Assistants that service the refugees with health care and in turn assess their mental health. While we consider attuning to moods in Heidegger’s sense as pervasive to the human existence, we consider the numeration of mental health by the medical assistants using a screening tool as equally significant. Comprehending how states of mental health are assessed in our case, we argue, requires that we pay attention to both the quantification of mental health by a screening tool as well as the ways that the experience of moods shape the assessments done by the health care professionals. Taking this analytical approach, we show how the assessment of the mental health of refugees by Medial Assistants in a camp setting were inseparably both a question of sensing as well as numeration. Where sensory experience may not be ‘enough’ on its own to warrant referral in the context of the health care infrastructure of the camp, and therefore the agency of numeration is a force that works well as an ally to the sensing of moods impressed on the medical assistants.

description: In this paper, a qualitative trailing research approach is used, combined with information infrastructure theory to conduct a formative evaluation on an empirical project in North Norway. In this project parts of the clinical information in the electronic health record (EHR) were structured as openEHR archetypes to enable automatic reuse of data from the EHR system to a national medical quality registry. We explore the design- challenges when structuring clinical information for different purposes. Hence, we ask the following research question: What are the premises for reusing clinical information for both primary and secondary purposes? The paper aim to contribute with empirical results and discuss the importance of understanding the prerequisites and implications of reusing clinical information for a duality of purposes. As results we outline three important issues to address. 1) the demand for attaching context when reusing variables, 2) how to ensure reusing the right data, and 3) the challenges of granulating the variables. Lessons learned indicates that governance and competence are the most important prerequisites for improving data usability by structuring clinical information.

We elicit 3 cases of digital transition that took place at part of the contingency plan, that was executed in the Danish healthcare sector. It was a necessity in order to support the physical distancing between patient and healthcare staff and new treatment trajectories. We analyze the 3 digital transitions by looking at the constraining and enabling factors for implementation the transitions and discuss how the transitions where related to the installed base (EPIC/HER system) and its governance model of IT-infrastructures in the Danish healthcare system.
Stigma of addiction and mental health in dental settings : patients' experiences
Creators: name: Alan, Rana
Publisher: name: University of British Columbia
Year: 2014

description: Objectives: The objective of this study was to explore the nature of stigma experienced by dental patients who have substance use and mental health issues. Methods: Semi-structured interviews were conducted with a purposefully selected group of 13 English-speaking participants (7 males) who struggled with a variety of substance use and/or mental disorders, and lived in one of two treatment centres. An interview guide containing open-ended questions was used to discuss their experiences with dental professionals, and their perceptions of stigmatization. All interviews were audio-recorded, transcribed verbatim and analyzed using a qualitative thematic analysis. Results: Analysis of about 300 pages of interview transcripts demonstrated that participants perceived stigma in dental settings when they were viewed as “junkie” or “crazy”, were negatively stereotyped, and finally were rejected as patients or received negative attitude and substandard care from dentists who were misusing their position of power. Lack of or poor understanding and education about issues of addiction and mental health were pointed out as the origin of stigma. Positive experiences with dental professionals were characterized by empathy, reassurance and communication, which were empowering for patients. Conclusion: Individuals with substance dependence and mental health issues felt stigmatized by some dental professionals who they felt had labelled, stereotyped, and discriminated against them; making them feel disempowered. Findings of the study highlighted the need to better prepare current and future dentists to address the oral care of patients with substance dependence and mental illness in their clinical practice.
title: Opening-up digital platforms to accommodate patient-generated healthcare data
Creators: name: Paparova, Dragana

Year: 2021

description: This paper investigates the process of opening-up digital platforms to accommodate patient-generated healthcare data (PGHD) and argues that in data platforms, barriers arise due to the entanglement of technology and policy. The empirical setting for the study is the opening up of a Norwegian eHealth platform for PGHD captured by external vendor technologies. The possibility to accommodate PGHD opens up new innovation arenas by recombining data from multiple sources and actors. However, such process is prone to a unique set of challenges when innovation is centered around data, instead of functionalities, such as: 1) open-up the data core using boundary resources; 2) control patient data across long chains of actors; 3) establish uniform rules to co-create data value. The findings show that the proves of opening up data platforms faces legislative barriers which should be overcome in a way that technology and policy enable each-other.

After separating a signal from the two-particle decay of neutral charmed mesons and estimating the cross section for charm production at a threshold energy σ(cč)=7.1 \pm 2.4(stat.) \pm 1.4(syst.) \mub/nucleon, some properties of D mesons are investigated. These include the dependence of the cross section on the target mass number (its A dependence); the behavior of the differential cross sections dσ/dpt2 and dσ/dxF; and the dependence of the parameter α on the kinematical variables xF, pt2, and plab. The experimental results in question are compared with predictions obtained on the basis of the FRITIOF7.02 code.

It is found that the UED model has a substantial effect on the scaling of the fermion masses, including both quark and lepton sectors, whilst the radiative effects on the unitarity triangle is not a sensitive test in this model. Also, for this model, the renormalization invariants $R_{13}$ and $R_{23}$ describe the correlation between the mixing angles and mass ratios to a good approximation, with a variation of the order of $λ^4$ and $λ^5$ under energy scaling respectively.

description: Electric-field controlled exchange bias in a heterostructure composed of the ferromagnetic manganite La0.7Sr0.3MO3 and the ferroelectric antiferromagnetic BiFeO3 has recently been demonstrated experimentally. By means of a microscopic model Hamiltonian we provide a possible explanation of the origin of this magnetoelectric coupling. We find, in agreement with experimental results, a net ferromagnetic moment at the BiFeO3 interface. The induced ferromagnetic moment is the result of the competition between the e_g-electrons double exchange and the t_2g-spins antiferromagnetic superexchange that dominate in bulk BiFeO3. The balance of these simultaneous ferromagnetic and antiferromagnetic tendencies is strongly affected by the interfacial electronic charge density which, in turn, can be controlled by the BiFeO3 ferroelectric polarization.

description: Reporting from an ethnographic study on municipal welfare provision, we focus on care workers’ “data discipline” when engaging in result-documentation within rehabilitation work. We show how the care workers’ own approach to result- documentation is a different kind of “data discipline” than the one called for by municipal management and supplemented by the digital care record. To unfold the analysis we draw on insights from Science and Technology Studies and Computer Supported Cooperative Work. We conclude the paper arguing that “data discipline” is practiced by care workers, they, however, engage in a different kind of data discipline.
Accuracy of differential item functioning detection methods in structurally missing data due to booklet design
Creators: name: Sandilands, Debra Anne
Publisher: name: University of British Columbia
Year: 2014

description: Differential item functioning (DIF) analyses are used to analyze structurally missing data (SMD) due to balanced incomplete block (BIB) booklet designs commonly used in large scale assessments (LSAs). Only one DIF method, the Mantel Haenszel (MH) method, has previously been studied in this context. The purposes of this study were to investigate and compare the power and Type I error rates of an additional DIF method, the IRT-based Lord’s Wald test, with the MH method and to extend the research on methods of forming the MH matching variable (MV) by proposing and testing a modification to the MH MV in the SMD context. A simulation study investigated the effects of sample size, ratio of group sizes, test length, percentage of DIF items, and differences in group abilities on the power and Type I error rates of four DIF methods: the IRT-Lord’s and MH using a block-wise, a booklet-wise, and a modified MV. The study design was selected to reflect authentic situations in which DIF might be investigated in LSAs that typically use BIB designs. The three MH methods maintained better Type I error rates than the IRT-Lord’s method which was inflated when the group sample sizes were unequal. None of the four methods had high power to detect DIF at the smallest sample size (1200). In the other sample size conditions the IRT-Lord’s method had high power to detect DIF only when group sizes were equal. None of the MH methods had high power when the group mean ability levels differed, nor when the proportion of DIF in the MV was high. These results indicate that DIF may go undetected in many realistic SMD conditions, potentially undermining the validity of score comparisons across groups. Recommendations to maximize DIF detection in SMD include using the MH method with a block-wise MV, ensuring a large overall sample size, and over-sampling small policy-relevant groups to result in more balanced group sample sizes. Results also indicate that other sources of validity evidence to support score comparability should be provided since DIF analyses cannot yet be solely relied upon for this purpose.

description: This paper reports on the results of a secondary analysis of qualitative and quantitative research data focused on the socio-demographic and -economic dimension of digital health service and telemedicine use in German rheumatology care. The qualitative data analysis revealed that particularly age, place of residence and economic wealth are attributed a high relevance for the use of digital health through patients. Among physicians, age in particular was highlighted to influence digital services. Access to technical equipment is unequally distributed in society, leading to a wealth gap, which, according to participants, should find greater consideration. The quantitative data suggested correlation between the location of medical practice and telemedicine use, which might indicate poorer infrastructure in rural areas in Germany. These results are transferred to Bourdieu's theory of social space (1979) and types of capital (1986). The individual positioning in social space is associated with health-enhancing privilege and opportunities to parts of society. This may also include digital health use, which according to our data depends in particular on the individual economic capital of each person. The influence of social, cultural and symbolic capital on digital health has yet to be explored, based on further primary data research.
title: Democracy and the politicization of personal health data: the Norwegian Smittestopp case

description: In early 2020, at the onset of the coronavirus pandemic, many countries developed and introduced contact-tracing apps. These apps use one or more of several cell phone capabilities to notify citizens when they should enter self-quarantine because of close contact with an infected individual. Norway released a contact tracing app called Smittestopp in April 2020 which, though initially widely used, was also met with criticism for the way it handled personal health data. Shortly after Amnesty International issued a press release calling the app a surveillance technology, it was rescinded, and a different solution developed. This paper discusses Smittestopp as an example of the politicization of personal data in the context of a state of exception, in this case the covid-19 pandemic. The combination of the politicization of personal data and a miscalculation of how long the pandemic might last contributed to the app’s negative reception both domestically and internationally. The paper argues that while the case did present a short-term challenge to Norway’s democratic institutions, the context of the state of emergency coupled with other actions the Norwegian government has taken to curb infection rates indicates that these challenges were temporary and not a serious threat.
title: Exploration of ethical issues in the implementation of digital monitoring technologies in municipal health care services

description: The study is based on a research and innovation project on adoption and use of digital monitoring in municipal care services. The evolving use of technology is considered to meet future challenges in health and care services. However, the use of technological solutions in this context has also led to several challenges, and in this study, we focus on the ethical consequences of using welfare technology. Implementation projects are particularly relevant in this context because different stakeholders with different interest, values, assumptions need to collaborate closely and build integrated solutions to make such projects successful. Furthermore, it is a challenge to predict future consequences of using emerging technologies and we argue that ethical assessments must be part of the implementation process.

description: The faithful storage of a quantum bit of light is essential for long-distance quantum communication, quantum networking and distributed quantum computing. The required optical quantum memory must, first, be able to receive and recreate the photonic qubit and, second, store an unknown quantum state of light better than any classical device. These two requirements have so far been met only by ensembles of material particles storing the information in collective excitations. Recent developments, however, have paved the way for a new approach in which the information exchange happens between single quanta of light and matter. This single-particle approach allows one to address the material qubit and thus has fundamental advantages for realistic implementations: First, to combat inevitable losses and finite efficiencies, it enables a heralding mechanism that signals the successful storage of a photon by means of state detection. Second, it allows for individual qubit manipulations, opening up avenues for in situ processing of the stored quantum information. Here we demonstrate the most fundamental implementation of such a quantum memory by mapping arbitrary polarization states of light into and out of a single atom trapped inside an optical cavity. The memory performance is analyzed through full quantum process tomography. The average fidelity is measured to be 93% and low decoherence rates result in storage times exceeding 180μs. This makes our system a versatile quantum node with excellent perspectives for optical quantum gates and quantum repeaters.

title: Support for Informal Caregivers: Use of Infrastructures
Creators: name: Tellioğlu, Hilda
Publisher: name: European Society for Socially Embedded Technologies (EUSSET)
Year: 2021

description: Informal health caring became a substantial part of our society. In Europe, official health care institutions cannot really cover the required care activities without the involvement of family members in caring activities. This role was taken by informal caregivers for a long time already. This paper tries to bring up this crucial setting into attention of health care community by identifying caregivers’ needs and requirements, mapping infrastructural elements to caregivers’ needs to achieve a satisfactory product, technology and service provision in this area, by suggesting an interconnected health care infrastructure as a possible solution. This analysis ends up in a more complex interconnected care infrastructure consisting of people and technology components, in the tradition of research on socio technology.

description: User mobilization plays a critical role in bottom-up processes of infrastructural transformation. In this study, we take a user perspective to how infrastructures transform, and investigate the work required to mobilize users. Our research is based on a case study of a project developing a novel solution for supporting data sharing in patient handovers in the context of primary care in the municipality of Oslo. We focus on the work of user representatives in the project activities, and specifically in their effort to engage their local organizations. In the analysis we identify three types of work for user mobilization: the work to identify benefits, anchor in the local leadership, and give a sense of ownership. We contribute to the literature on bottom-up user-driven change processes by showing the work required for user mobilization and conclude with implications for supporting users’ learning.

description: The multiplicity of actors and the opacity of technologies involved in data management, algorithm crafting and systems ́ development for the deployment of Artificial Intelligence (AI) in healthcare create governance challenges. This study analyzes extant AI governance research in the context of healthcare focusing on accountability, transparency and explainability. We find that a significant part of this body of research lacks conceptual clarity and that the relationship between accountability, transparency and explainability is not fully explored. We also find that papers written back in the 1980s, identify and discuss many of the issues that are currently discussed. Up to today, most published research is only conceptual and brings contributions in the form of frameworks and guidelines that need to be further investigated empirically.
Hysteretic "Magnetic-Transport-Structural" Transition in "114" Cobaltites: Size Mismatch Effect

description: The triple "magnetic-transport-structural" transition versus temperature in three series of "114" cobaltites - Y1-xYbxBaCo4O7, Y1-xCaxBaCo4O7 and Yb1-xCaxBaCo4O7 - has been studied using magnetic, transport and differential scanning calorimetric measurements. The effect of the size mismatch σ2, due to cationic disordering at the Ln sites upon such a transition is shown for the first time in a triangular lattice. We show that increasing has an effect of increasing TS dramatically, while the size mismatch σ2 at the Ln sites decreases TS substantially. Moreover, the cationic mismatch at the Ln sites modifies the nature of the hysteretic transition by turning the sharp first order transition seen in the undoped samples into an intermix of first and second order transitions. These results are discussed on the basis of the particular nature of the high temperature form which exhibits a hexagonal close packed structure (space group: P63mc) with respect to the low temperature orthorhombic form (space group: Pbn21), the latter corresponding to a distortion of the former due to a puckering of the kagomé layers.

Phase stability of a reversible supramolecular polymer solution mixed with nanospheres

Subjects: subject: Soft Condensed Matter (cond-mat.soft)

description: Theory is presented for the phase stability of mixtures containing nanospheres and non-adsorbing reversible supramolecular polymers. This was made possible by incorporating the depletion thickness and osmotic pressure of reversible supramolecular polymer chains into generalized free-volume theory, recently developed for investigating the phase behaviour of colloidal spheres mixed with interacting polymers [Adv. Colloid Interface Sci. 143 (2008) 1-47]. It follows that the fluidfluid phase stability region where reversible supramolecular polymer chains can be mixed with nanospheres is sensitive to the energy of scission between the monomers and to the nanoparticle radius. One can then expect the fluidfluid coexistence curves to have a strong dependence on temperature and that shifting of phase boundaries within a single experimental system should be possible by varying the temperature. The calculations reveal the width of the stability region to be rather small. This implies that phase homogeneity of product formulations containing reversible supramolecular polymers is only possible at low nanoparticle concentrations.
