Book excerpt: This work resulted in the development of multiple distinct and novel methods of cheaply producing large numbers of biologically derived, complex, 3-dimensional microstructures in a multitude of possible compositions. The biologically derived structures employed in this work were diatoms, a type of single celled algae, which grow complex silica shells in species-specific shapes. Due to the wide diversity of naturally occurring diatom shapes (on the order of 105), and the flexibility in tailoring chemical compositions using the methods developed here, real potential exists for cheaply mass-producing industrially relevant quantities of controlled shape and size 3-d particles for the first time. The central theme of this research is the use of diatoms as a transient scaffold onto which a coating is applied. After curing the coating, and in some cases firing the coating to form ceramic, the diatom can be selectively etched away leaving a free standing replica of the original structure with the salient features of the pre-form intact, but now composed of a completely different material. Using this concept, specific methods were developed to suit various precursors. Dip coating techniques were used to create epoxy diatoms, and silicon carbide diatoms. The Sol-Gel method was used to synthesize zirconia diatoms in both the tetragonal and monoclinic phases. A multi step method was developed in which previously synthesized epoxy diatoms were used as a template for deposition of a silicon carbide precursor and then heat treated to produce a silicon carbide/carbon multi-component ceramic. A hydrothermal reaction was also developed to convert Titania diatoms to barium titanate by reaction with barium hydroxide. Finally, the device potential of diatom-derived structures was conclusively demonstrated by constructing a gas sensor from a single Titania diatom. Under suitable conditions, the sensor was found to have the fastest response and recovery time of any sensor of this type reported in the literature. Furthermore, this work has laid the groundwork for the synthesis of many other tailored compositions of diatoms, and provided several compositions for device creation.

Download or read book Gaia Alchemy written by Stephan Harding and published by Simon and Schuster. This book was released on 2021-12-21 with total page 453 pages. Available in PDF, EPUB and Kindle. Book excerpt: • Examines how integrating important alchemical images with Gaian science can offer insights into our interconnectedness with Gaia • Looks at how the four components of the living earth--biosphere, atmosphere, hydrosphere, and lithosphere--mesh with the four elements of alchemical theory and the four functions of consciousness as understood by depth psychology • Offers guided meditations and contemplative exercises to open your receptivity to messages from the biosphere and help you connect more deeply with Gaia During the scientific revolution, science and soul were drastically separated, propelling humanity into four centuries of scientific exploration based solely on empiricism and rationality. But, as scientist and ecologist Stephan Harding, Ph.D., demonstrates in detail, by reintegrating science with profound personal experiences of psyche and soul, we can reclaim our lost sacred wholeness and help heal ourselves and our planet. The book begins with compelling introductions to depth psychology, alchemy, and Gaia theory--the science of seeing the Earth as an intelligent, self-regulating system, a theory pioneered by the author’s mentor James Lovelock. Harding then explores how alchemy, as understood through the depth psychology of C. G. Jung, offers us powerful methods of reuniting rationality and intuition, science and soul. He examines the integration of important alchemical engravings, including those from L’Azoth des Philosophes and the Rosarium Philosophorum, with Gaian science. He shows how the seven key alchemical operations in the Azoth image can help us develop deeply transformative experiences and insights into our interconnectedness with Gaia. He then looks at how the four components of the living Earth--biosphere, atmosphere, hydrosphere, and lithosphere--mesh not only with the four elements of alchemical theory but also with the four functions of consciousness from depth psychology. Woven throughout with the author’s own experiences of Gaia alchemy, the book also offers guided meditations and contemplative exercises to open your receptivity to messages from the biosphere and help you develop your own Gaian alchemical way of life, full of wonder and healing.

Download or read book Diatom Morphogenesis written by Vadim V. Annenkov and published by John Wiley & Sons. This book was released on 2021-11-23 with total page 452 pages. Available in PDF, EPUB and Kindle. Book excerpt: DIATOM MORPHOGENESIS A unique book presenting the range of silica structures formed by diatoms, theories and hypotheses of how they are made, and applications to nanotechnology by use or imitation of diatom morphogenesis. There are up to 200,000 species of diatoms, each species of these algal cells bearing an ornate, amorphous silica glass shell. The silica is structured at 7 orders of magnitude size range and is thus the most complex multiscalar solid structure known. Recent research is beginning to unravel how a single cell marshals chemical, physical, biochemical, genetic, and cytoskeletal processes to produce these single-cell marvels. The field of diatom nanotechnology is advancing as this understanding matures. Diatoms have been actively studied over the recent 10-20 years with various modern equipment, experimental and computer simulation approaches, including molecular biology, fluorescence-based methods, electron, confocal, and AFM microscopy. This has resulted in a huge amount of information but the key stages of their silica morphogenesis are still not clear. This is the time to reconsider and consolidate the work performed so far and to understand how we can go ahead. The main objective of this book is to describe the actual situation in the science of diatom morphogenesis, to specify the most important unresolved questions, and to present the corresponding hypotheses. The following areas are discussed: A tutorial chapter, with a glossary for newcomers to the field, who are often from outside of biology, let alone phycology; Diatom Morphogenesis: general issues, including symmetry and size issues; Diatom Morphogenesis: simulation, including analytical and numerical methods for description of the diatom valve shape and pore structure; Diatom Morphogenesis: physiology, biochemistry, and applications, including the relationship between taxonomy and physiology, biosilicification hypotheses, and ideas about applications of diatoms. Audience Researchers, scientists, and graduate students in the fields of phycology, general biology, marine sciences, the chemistry of silica, materials science, and ecology.

This book was released on 2019-06-15 with total page 35 pages. Available in PDF, EPUB and Kindle. Book excerpt: Research stimulated by curiosity brings out new pieces that make up the puzzle oflife and invention provides the tools to assemble and interpret it. The IndustrialRevolution of past centuries has brought innovations not accompanied by a farsightedvision of the consequences that are manifesting in this globalized twenty-firstcentury, particularly with an increase in energy demand and global warming. Theemerging biotechnology revolution, which applies technology to biological systems,could solve these problems without further deleterious effects if driven bysustainable development. Research and development institutes, subsidized bygovernments, are looking for renewable and sustainable energy resources that wouldreplace polluting fossil fuels nearly depleted.Recently the investigation of the marine microalgae's potential in biotechnologicalapplications is increasing by the realization that the ocean is a relatively untappedsource of energy biomass and novel biomolecules. Microalgae mainly represent thelast generation suitable feedstock for the transport sector, but due to theirbiochemical versatility are useful also for many others industrial fields such asmedical, pharmaceutical, food and cosmetic. Nowadays, biofuel production frommicroalgae biomass is still in progress; the efficiency of each step during the wholeprocess, from culturing to refining, needs to be improved to get yield economicallyreasonable. Coupling each other different industrial applications could lead toovercome the substantial investments with proper earnings making, hopefully in thenext future, this living energy source lucrative, therefore commercially feasible.In the last decades, researchers are focusing their attention on Diatoms, a taxon ofmicroalgae characterized by silica walls derived from secondary symbiotic event.Diatoms are affected by seasonal exponential growth called blooms that place themat the base of the oceans food chain, permit about 40% of atmospheric CO2 fixationand significant influence the biogeochemical cycle of the macronutrients: silicon(Si), nitrogen (N), phosphorus (P). This microalgae's group is a promising candidatefor biodiesel production because of their great lipid accumulation like reserve storagecompound mainly in the form of triacylglycerols (TAG), converted into biodieselthrough a reaction of trans-esterification.The aim of this thesis were the evaluation of the growth curves and biochemicalcomposition (lipids, carbohydrates and proteins) of the marine diatom CyclotellaCryptica grown in batch system by administering the average of the standard mediumf/2 daily or only the day of the inoculation. The growth curve were obtained bymonitoring daily the cellular density (cells/mL) with an optical microscope combinedwith a Bürker chamber. The biological macromolecules quantification, lipids,carbohydrates, and proteins were realized by Folch modified – MTBE, Dubois andLowry methods, respectively. Furthermore, the lipids composition werecharacterized both by Thin Layer Chromatography (TLC) and Nuclear MagneticResonance (NMR)-Eretic method.The results shows that the daily supply of the medium f/2 induce high cell density(2250000±77567 cells/mL) and biomass dry weight (1441.79±148.35 mg/L) thatmainly consist of proteins (88%) and lipid fraction is predominantly composed byphospholipids (PL). Conversely, administering the medium f/2 only the first day letthe diatoms in a starvation condition defined by a little cell density (192222 ± 26851)and biomass dry weight (205.90±22.24 mg/L) with a significant increase in therelative amount of storage compounds: carbohydrates (19%) and lipid (33%)predominantly in form of triacylglycerols (TAG).Typically, microalgae are growth at first in laboratories under strict controlledcondition in closed photobioreactors and then transferred to open-pounds for largescaleproduction.
