The synthesis of PANI/Ag hybrid materials has been carried out via a rapid chemical oxidative, in-situ polymerisation method, using silver nitrate and ammonium peroxydisulfate as oxidant precursors. These species react together to produce Ag2+, an oxidising intermediate which has greater oxidising power than either persulphate or Ag+ alone. The reaction thus proceeds at a much accelerated rate than that of pure PANI, approximately 6 times faster. Various characterisation techniques were used to characterise this new hybrid material, PANI-Ag. UV-vis absorption spectroscopy was used to follow the formation of polymer over time and monitor the rate at which the reaction progresses for both PANI and PANI-silver. It is evident from the absorption spectra that the polymer forms via the fully-oxidised pernigraniline state initially, before reducing back into the more stable emeraldine salt form. This process is significantly accelerated using both APS and AgNO3, as opposed to when using APS or AgNO3 alone. These new composites could potentially find use as functional materials for the printed electronics industry where new processable, hybrid materials as required for applications in sensing, memory, logic and photovoltaics.

Polyaniline (PANI) is an organic polymer that has generated significant interest as an electrically conductive material component, and is used in applications such as sensors and flexible displays. A significant number of PANI-based devices have been prepared using inkjet printing; a fabrication technique favoured for its additive patterning ability and its efficient use of material. Combining precious metals and conducting organic polymers through compositing provides combinatorial materials, potentially possessing both the properties of the metallic component and the conducting polymer, as well as unique ensuing properties due to the compositing itself. The type of research is critical for driving innovation in materials research. Exploiting an established oxidative polymerisation protocol for producing stable nanodispersions of PANI was used where the standard oxidant was replaced with HAuCl4 or AgNO3 at a range of monomer:oxidant ratios to produce a range of composite dispersions. The morphology and populations of the metallic structures (including spherical nanoparticles and nano-whiskers), as well as the quality of the PANI were shown to be influenced by the concentration and type of oxidant used. This area of research is currently in its infancy where the research is focusing on demonstrating composite synthesis rather than the application of these materials for device fabrication. However, anticipated applications of these composite materials include noble metal deposition, electro-catalysis, neural tissue engineering, sensors, photovoltaic cells and memory devices.

David Lynch has been accused for decades of sexism and even misogyny in his work, due largely to frequent depictions of violence against women. Yet others see in Lynch's work the deification of the female, and actresses like Laura Dern and Naomi Watts jump at every opportunity to work with him. "He is the master of the juxtaposition of the creepy and the sweet, the sexual and the chaste," wrote W's Lynn Hirschberg. "And at the heart of this tense, intriguing friction, you will always find Lynch's women." The Women of Lynch is a deep, provocative dive into this paradox, featuring ten essays, thought pieces and impressionistic interpretations of Lynch's depiction of women on screen, by an eclectic array of accomplished female critics, scholars, performers, and writers, each tackling this vexing conundrum in her own unique way. The book also contains an interview with actress Mädchen Amick (Shelly Johnson in Twin Peaks) where she gives first hand knowledge on what it is like to be a woman of Lynch. Lisa Hession interviews the original woman of Lynch, Charlotte Stewart (Eraserhead, Twin Peaks) about being the actress with longest active span of working with David Lynch. This is the first essay book about the work of David Lynch by all female writers. Readers will enjoy The Women of Lynch: A Collection of Essays. This book contains essays by: x. An Introduction by Philippa Snow 1. The Uncanny Electricity of David Lynch's Women by Leigh Kellmann Kolb 2. Women's Films: Melodrama and Women's Trauma in the Films of David Lynch by Lindsay Hallam 3. A Colorless Sky: On the Whiteness of Twin Peaks by Melanie McFarland 4.
