How does the past live in us? Do we inherit our ancestors' memories as we do their physical characteristics? In the nineteenth century, mainstream science embraced a long-standing superstition: the belief that memory could be inherited. Scientists reasoned that, just as bodies were reproduced from generation to generation, so were thoughts, memories, and cultural achievements. Heredity and identity were no mere family matter, but the basis of nations. The glories and sins of the past were not gone: they remained in the tissues of living people, who could be honored or blamed accordingly. Organic Memory surveys the literary and scientific history of an idea that will not go away. Focusing on the years between 1870 and 1918, Otis explores both the origins and the consequences of the idea that memories can be inherited. The organic memory theory contributed to the genocidal programs of the Third Reich, and it erupts in pop-psychology, racist propaganda, and ethnic cleansing. To track the spread, intensity, and endurance of this especially powerful idea, Otis singles out major authors whose work reinforced or ridiculed belief in organic memory. They include writers who were internationally influential yet who simultaneously represented their national traditions: Thomas Mann, Sigmund Freud, C. G. Jung, Emile Zola, Thomas Hardy, Miguel de Unamuno, P�o Baroja, Emilia Pardo Baz¾n, and even Sir Arthur Conan Doyle. The debates over the human genome project and the explosions of ethnic violence in the former Yugoslavia, in Azerbaijan, Somalia, and elsewhere demonstrate how seriously organic memory continues to affect modern medicine and politics.

Brain damage can cause memory to break down in a number of different ways, the analysis of which can illuminate how the intact brain mediates memory processes. After first considering the problems involved in assessing memory, this book provisionally advances a taxonomy of elementary memory disorders and, for each in turn, reviews both the specific processes that are disrupted and the lesions responsible for the disruption. These disorders include short-term memory deficits, deficits in previously well-established memory, memory decifits caused by frontal lobe lesions, the organic amnesias, the disorders of conditioning and skill acquisition. Particular attention is paid to the organic amnesias, about which we know the most, and to the contributions of animal models to our knowledge. Andrew Mayes argues that the memory deficits found in several neurological and psychiatric syndromes comprise co-occurring elementary memory disorders. Finally, he outlines the implications of his taxonomy for our understanding of normal memory. A wide audience of researchers and students will find Human Organic Memory Disorders a helpful guide to a complex problem area.

The convergence of mobile technologies combined with stricter power requirements and increasing demands have strained the current memory technology. Newer technologies such as phase changing, ferroelectric, and magnetic random access memories are unsatisfactory in meeting the new requirements. We propose a new memory technology based on our initial discovery of charge storage in C60 molecules within poly (4-vinyl phenol) (PVP). To understand the memory potential, we created single-layer devices consisting of ~30nm films of PVP+C60 sandwiched between aluminum (Al) electrodes. Current versus voltage (I-V) sweeps showed a significant hysteresis of 75nA, with distinguishable memory states. Room temperature charging of C60 was confirmed indirectly through capacitance versus voltage measurements and directly by monitoring the A1g characteristic peak of C60 during Raman measurements. We demonstrated memory operations by applying read-write-erase (RWE) pulses. The PVP+C60 devices exhibited memory retention for over 1 hour and response times of around 10ns. Characteristic hysteresis was demonstrated at the nanoscale. Conduction models were fitted at room temperature to the I-V curves. It was found that combination of direct and Fowler-Nordheim tunneling were the principle conduction mechanisms. For a more technologically viable memory device, we developed a multi-layer device structure, consisting of a polystyrene (PS) capping layer. The resulting asymmetrical I-V curve exhibited a hysteresis ratio of 103. RWE cycles were measured with clearly distinguishable states. The memory retentions were measured over 2 hours and the response time around 10ns. The stability of the multi-layer devices was improved. I-V measurements at temperatures varying from 4.2 K to 298 K were performed to construct a theoretical model. The I-V curves were found to be temperature independent and exhibited similar tunneling behaviors as the single-layer devices. A simple model for conduction and memory operation is proposed based on the I-V fits. These devices exhibit the characteristics needed to satisfy the new demands for memory application and have the potential of becoming the first universal memory technology. They possess the high speed, non-volatility, thermal stability, and potentially high memory densities to make them ideal for use in laptops, iPhones, mp3 players, portable video players, GPS systems, and other mobile devices.

During the 1980s, functional organic devices were born. For nearly twenty years, organic semiconductor technology has largely been the domain of traditional players within the microelectronics world, involving semiconductor companies, research laboratories, and government organizations. The print industry, a well-established community who shaped much of the Second Millennium, has joined the organic electronics quest during these first few years of the Third Millennium. This seemingly unlikely marriage of two worlds, the microelectronics and graphic print industries, shows incredible promise to spawn an entirely new method of electronics manufacture and, ultimately, whole new industries. The enhancements of organic semiconductor materials seen during the late 1990s and early 2000s have resulted in the fabrication of organic electronics in laboratory environments with impressive performance. Since the early 2000s, scientists have succeeded in applying printing-related technologies to create organic field effect transistors (OFETs) with micron-sized features. This has led to a widespread vision of developing printed electronic products, especially displays, sensors, and simple wireless products (such as RFID tags). The development of high-volume manufacturing platforms based on traditional graphic arts printing platforms naturally addresses demands on product cost and throughput. Moreover, graphics art printing technologies allow one to fabricate organic circuits directly onto low-cost sheet or roll substrates, including plastics and paper. Printed Organic And Molecular Electronics was compiled to create a reference that included existing knowledge from the most renowned industry, academic, and government experts in the fields of organic semiconductor technology, graphic arts printing, micro-contact printing, and molecular electronics. It is divided into sections that consist of the most critical topics required for one to develop a strong understanding of the states of these technologies and the paths for taking them from R&D to the hands of consumers on a massive scale. As such, the book provides both theory as well as technology development results and trends.

The genetic code appeared on Earth with the first cells. The codes of cultural evolution arrived almost four billion years later. These are the only codes that are recognized by modern biology. In this book, however, Marcello Barbieri explains that there are many more organic codes in nature, and their appearance not only took place throughout the history of life but marked the major steps of that history. A code establishes a correspondence between two independent 'worlds', and the codemaker is a third party between those 'worlds'. Therefore the cell can be thought of as a trinity of genotype, phenotype and ribotype. The ancestral ribotypes were the agents which gave rise to the first cells. The book goes on to explain how organic codes and organic memories can be used to shed new light on the problems encountered in cell signalling, epigenesis, embryonic development, and the evolution of language.
