As an organic semiconductor and a prototypical acceptor molecule in organic photovoltaics, C60 has broad relevance to the world of organic thin film electronics. Although highly uniform C60 thin films are necessary to conduct spectroscopic analysis of the electronic structure of these C60-based materials, reported C60 films show a relatively low degree of order beyond a monolayer. Here, we develop

Metal halide perovskites and related materials have sparked intense debate in the field of optoelectronic applications, including solar cells, light-emitting diodes, and lasers. Despite significant progress in improving device efficiency and stability, understanding the structure-property relationships remains largely elusive. This thesis presents an in-depth investigation of the structural dynami

Multidimensional poverty measures require implicit, if not explicit, trade-offs between different dimensions. One of the central values that has to be weighed against other values in this context is the value of life, since this is a central part of multidimensional poverty measures—often proxied for by longevity or child mortality. Different ways of weighting value dimensions (even weighting dime

This case study illustrates how family members can assist in the care of teenagers with diabetes but that there are also serious risks actualized by such involvement. In particular, it highlights ethical complications that arise when the role of a family member is changed from ‘parent’ to ‘care provider’. The ‘counseling, self-care, adherence’ (CSA) approach offers a look at the role that family c

This chapter introduces a new framework for thinking about climate justice. Climate change and climate negotiations actualize equity considerations in at least three relevant dimensions: distributions of benefits and burdens across countries, within countries, and across individuals in the world. Our proposed framework enables researchers and policymakers to visualize and combine different equity

The debate around whether or not torture can be morally justified have been intense ever since September 11, 2001, and gained further actuality as the Obama administration in the U.S. released documents concerning interrogational techniques used by the C.I.A. In this chapter, I examine the notion of torture often used in these debates, within the field of academic philosophy as well as in the publ

This paper introduces incommensurability, its potential relevance to population-level bioethics, and thecontributions to the special issue. It provides an overview of recent research on incommensurability, outlines somereasons to believe in its possibility and relevance, and presents some problems and opportunities that arise onceone accepts that incommensurability is possible.

Context. Neutron-capture elements represent an important nucleosynthetic channel in the study of the Galactic chemical evolution of stellar populations. For stellar populations behind significant extinction, such as those in the Galactic centre and along the Galactic plane, abundance analyses based on near-infrared (NIR) spectra are necessary. Previously, spectral lines from the neutron-capture el

This article presents an approach to how to make reasonable social choices when independent criteria (e.g., prioritarianism, religious freedom) fail to fully determine what to do. The article outlines different explanations of why independent criteria sometimes fail to fully determine what to do and illustrates how they can still be used to eliminate ineligible alternatives, but it is argued that

This paper addresses how to think about the permissibility of introducing deadweight costs (so-called 'ordeals') on candidate recipients of goods in order to attain better outcomes. The paper introduces some distinctions between different kinds of value dimensions that should be taken into account when such judgements are made and draws from the literature on comparisons across different value dim

A notorious problem that has recently received increased attention in axiology, normative theory and population ethics is the apparent ubiquity of what can be generally called nondeterminacy. This paper illustrates how nondeterminacy can spawn cyclical rankings. So, accepting that practical reasons can admit of nondeterminacy challenges the widely held idea that ‘better than’ is transitive. As a r

This article shows that introducing the positive comparative relation parity only helps one block so-called “Spectrum Arguments” in order to avoid their unsavoury implications if one specifies parity in a specific way with respect to its persistence. The article illustrates how parity must both admit of persistency and be weakly non-persistent for parity to block Spectrum Arguments, and identifies
