Navigating through the maze: the practical issues of conducting research for novices

New postgraduate students embark on their research journey typically with little or no experience in doing research. Supervisors and other more experienced student researchers might help them to find their feet during the first few weeks of their research by sharing their own experience of how they solved similar problems during their research. In this way each novice researcher can learn and benefit from other researchers´ ways of resolving problems. This paper discusses the real concerns that researchers reflected upon during a two-day research workshop, where researchers share problems, exchange ideas for overcoming them and learn from each other´s experiences of conducting research. The output from the workshop is in the form of hints and tips that can guide novice researchers when faced with initial problems. The paper can also be used by a department to induct a novice researcher into their environment.

Joseph Mainzer (1801-1851) and the popularisation of choral singing in Britain

Singing master Joseph Mainzer came to England in 1841 as a political refugee from Germany. Through his music schools, his textbook Singing for the Million, and his journal Mainzer’s Musical Times (today The Musical Times) he contributed significantly to the popularisation of choral singing in Britain. This essay takes Mainzer’s political background as a starting point to investigate the complex relationship between refuge and artistic production. It is argued that the latter was deeply informed by the former. Mainzer not only transferred choral traditions but also a politicised concept of popular culture which started to take hold in pre-revolutionary Vorma¨rz-Germany. The case study is integrated into the larger framework of Anglo-German cultural relations and political refuge in mid-nineteenth century Britain.

A general one-pot strategy for the synthesis of high-performance transparent-conducting-oxide nanocrystal inks for all-solution-processed devices

For all-solution-processed (ASP) devices, transparent conducting oxide (TCO) nanocrystal (NC) inks are anticipated as the next-generation electrodes to replace both those synthesized by sputtering techniques and those consisting of rare metals, but a universal and one-pot method to prepare these inks is still lacking. A universal one-pot strategy is now described; through simply heating a mixture of metal-organic precursors a wide range of TCO NC inks, which can be assembled into high-performance electrodes for use in ASP optoelectronics, were synthesized. This method can be used for various oxide NC inks with yields as high as 10 g. The formed NCs are of high crystallinity, uniform morphology, monodispersity, and high ink stability and feature effective doping. Therefore, the inks can be readily assembled into films with a surface roughness of 1.6 nm. Typically, a sheet resistance of 110 Ω sq-1 can be achieved with a transmittance of 88%, which is the best performance for TCO NC ink-based electrodes described to date. These electrodes can thus drive a polymer light-emitting diode (PLED) with a luminance of 2200 cdm-2 at 100 mA cm-2.
