Wijsman Hyperspaces: Subspaces and Embeddings

In this paper, topological properties of Wijsman hyperspaces are investigated. We study the existence of isolated points in Wijsman hyperspaces. We show that every Tychonoff space can be embedded as a closed subspace in the Wijsman hyperspace of a complete metric space which is locally R.Comment: 6 page

Diamond and sp² carbon for green energy applications

Carbon is a ubiquitous element on earth, with 6 protons, electrons, and neutrons. It is tetravalent, with a range of hybridised bonding configurations, it can form materials with superlative and varied properties. These materials range from soft and conductive sp2 bonded allotropes like graphite and carbon nanotubes, to the insulating and hardest natural material on earth, sp3 bonded diamond. The first half of this thesis presents an investigation of the properties of a promising novel carbon nanomaterial, CNS, and its application to ultracapacitor electrodes for the first time. High surface area conductive carbon nanomaterials are capable of high power and long service life energy storage in ultracapacitors, a critical green technology. The development of this technology to increase energy density to compete with chemical batteries could accelerate a transition to sustainable energy infrastructure. CNS/polymer composite electrodes were assembled using a conductive diamond collector substrate, then characterised using electrochemical techniques to measure capacitative performance. The second half of this thesis concerns the development of amperometric dissolved oxygen sensors for extreme environments. Diamonds controllable electronic properties, corrosion resistance, wide electrochemical window, and resistance to fouling make it an ideal potential material for this application. Conductive boron doped diamond electrodes were functionalised with platinum nanoparticles. Aphotolithographyprocesswasusedtoproduceanarrayofmicrodiscelectrodesusingan SU-8 photoresist mask, for the first time in this application and material system. A custom electrochemical cell was designed and built to provide a new electrochemical capability to the lab at approximately 1/10th the cost of a commercial solution; the project will be made open source. The microdisc array was tested as an oxygen sensor using the cell; calibration standards were produced by controlling the flow of oxygen and nitrogen gasses through the cell. A control measurement was provided for by a calibrated oxygen gauge incorporated into the test cell

Restoration of peatlands and greenhouse gas balances

In this chapter the impact of peatland restoration on greenhouse gas fluxes is discussed based on a literature review. Casestudies are presented covering different peatland types, different regions and different starting conditions

Multiple Loves: The Effects of Attachment with Multiple Concurrent Romantic Partners on Relational Functioning

In the present study, we sought to understand whether people in polyamorous relationships have similar attachment orientations with each of their partners. Further, we examined the extent to which the attachment relationship with a given partner affects relationship quality both within that relationship and across concurrent romantic relationships. We recruited a community sample of 357 people engaged in polyamory with at least two concurrent romantic partners. People engaged in polyamory exhibited secure attachment with both of their partners (low in avoidance and anxiety); specifically, these scores were lower than established norms. In terms of within-relationship effects, avoidance and anxiety with a specific partner were linked with lower levels of relationship functioning (relationship satisfaction, sexual satisfaction, satisfaction with emotional and sexual agreements, and commitment) for that specific relationship. However, there was no association between avoidance and anxiety with one specific partner and the relationship functioning in a different, concurrent romantic relationship (i.e., cross-relationship effects). These findings suggest that individuals engaged in polyamory treat these relationships as distinct and independent from one another—forming attachments with each partner based on the specifics of that relationship. Understanding attachment processes in polyamorous relationships provides new directions for exploring the diversities of intimate partnering and theory expansion
