The hole transporting medium in solid-state dye-sensitized solar cells can be utilized to harvest sunlight. Herein we demonstrate that a triphenylamine-based dye, used as hole-transporting medium, contributes to the photocurrent in a squaraine-sensitized solid-state dye-sensitized solar cell. Steady-state photoluminescence measurements have been used to distinguish between electron transfer and en

The polymer APFO3 was prepared with different molecular weights to study how the infiltration into nanoporous TiO2 films of different thickness depends on the size of the polymer. Also two different sizes of TiO2 nanoparticles were investigated to understand the effect of different pore size. It was observed that the lowest molecular weight polymer dissolved in chlorobenzene could infiltrate the n

Photoinduced energy conversion from multilayers of organic dye on dense TiO2 films was investigated in bilayer hybrid solar cells. Dye layers of varying thicknesses were prepared by spin-casting the star-shaped dye [tris(dicyano-vinyl-2-thienyl)phenyl]amine (1) from solutions onto dense TiO2 on conducting glass substrates. A spin-cast layer of poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate

We describe an experimental setup for investigating the transport of alkali ions through poly(p-xylylene) membranes. It consists of an ion source where a continuous beam of alkali ions is generated from a surface emitter. Via ion-optics the ions are guided to the main chamber where the interaction with the free-standing membranes of variable thickness is investigated as a function of the impact en

Studien handlar om hur de som bor i stadsdelen Augustenborg i Malmö använde och upplevde den avfallshantering som introducerades 2008. Hur hållbara avfallssystem kan åstadkommas diskuteras med utgångspunkt i användning och upplevelse av den lokala avfallshanteringen. De primära frågeställningarna är:• Vilka begrepp och kategorier skapar och använder invånarna när det gäller avfall i vardagen? Hur

Den här texten ger en bild av de förutsättningar och överväganden som låg till grund för skapandet av den nya Institutionen för kulturvetenskaper vid Lunds universitet. Det är en historieskrivning för framtiden men också en berättelse om den framtid som kunde förutses före 2009 när institutionen bildades. Det är en backspegelsberättelse, ett retrospektiv mot vilket det som då var framtid och nu är

PURPOSE: Intensive care unit (ICU) patients are particularly susceptible to developing pressure injuries. Epidemiologic data is however unavailable. We aimed to provide an international picture of the extent of pressure injuries and factors associated with ICU-acquired pressure injuries in adult ICU patients.METHODS: International 1-day point-prevalence study; follow-up for outcome assessment unti

BACKGROUND: The number of intensive care patients aged ≥ 80 years (Very old Intensive Care Patients; VIPs) is growing. VIPs have high mortality and morbidity and the benefits of ICU admission are frequently questioned. Sepsis incidence has risen in recent years and identification of outcomes is of considerable public importance. We aimed to determine whether VIPs admitted for sepsis had different

Purpose: Very old critical ill patients are a rapid expanding group in the ICU. Indications for admission, triage criteria and level of care are frequently discussed for such patients. However, most relevant outcome studies in this group frequently find an increased mortality and a reduced quality of life in survivors. The main objective was to study the impact of frailty compared with other varia

Reflecting the multiple ambiguities of its ordinary language use, the current scholarly use of the term(s) “medium”/“media” is fraught with contradictions. Starting out from the insight that the nucleus of any kind of communication is an act, in which an addresser presents an artefact and a task of interpretation to an addressee, which the latter is called upon to fulfil, anything else that accrue

The notion of memory is ambiguous in multiple ways. It can be an event, an act of memory; or it can consist of a structure conserving and organizing a set of facts. In the first case, it may involve the automatic retention of the ‘just evolved’ moment in the stream of consciousness, or it can be a deliberate act with a purpose to build up, or to search, the space of recorded facts. In the second c

Professor Adelle Blackett asks ‘what happens when labour law is forced to see itself in historically rooted, relational, and contextualised terms’? While refusing continuity for its own sake, Blackett stresses the need for developing spaces in which alternative and counter-hegemonic narratives about the purpose of (labour) law are taken seriously – those emerging from labour law’s peripheries in c

Within cognitive science, “blindness” to choice is commonly treated as typical of human cognition, implying unreliable agents who essentially lack any awareness of their own choices (e.g. Johansson et al., 2005, 2008; Hall et al., 2010, 2013). Within cognitive semiotics, however, choice awareness is seen as a continuous phenomenon, which is susceptible to the influence of a variety of factors. Man

Secularization denotes the changing role of religion in the modern period, such as the establishment of legal separation between state and religious authority; the decline in religious belief and practice; and the transformation of religious motifs and symbols into cultural or political ones. In history writing, the concept of secularization raises the fundamental question of the relation of moder
