The self-organization of bionanostructures into well-defined functional machineries found in nature has been a priceless source of ideas for researchers. The molecules of life, proteins, DNA, RNA, etc., as well as the structures and forms that these molecules assume serve as rich sources of ideas for scientists or engineers who are interested in developing bio-inspired materials for innovations in biomedical fields. In nature, molecular self-assembly is a process by which complex three-dimensional structures with well-defined functions are constructed, starting from simple building blocks such as proteins and peptides. This book introduces readers to the theory and mechanisms of peptide self-assembly processes. The authors present the more common peptide self-assembled building blocks and discuss how researchers from different fields can apply self-assembling principles to bionanotechnology applications. The advantages and challenges are mentioned together with examples that reflect the state of the art of the use of self-assembled peptide building blocks in nanotechnology.

Despite advances in the long-range electrostatic double-layer force, which depends strongly on ionic strength in water by using theoretical models such as DLVO (Derjaguin, Landau, Verwey, and Overbeek), the structure of confined water in air still remains widely unknown and has led to a variety of unexplained phenomena. This book bridges that gap by introducing a newly developed scanning probe miscroscopy (SPM) approach, which enables one to probe confined water at the molecular and atomic scale. Written by the developer of SPM, this book covers this new approach, as well as original approaches to addressing general interfacial water issues. It also introduces the cantilever-based optical interfacial force microscope (COIFM), which was invented by the author along with the methodology. The improved understanding will contribute to liquid-based nano- and bio-technologies such as lab-on-a-chip technologies, nanofluidic devices, dip-pen nanolithography, nano-oxidation, water-based granular interactions, liquid-based nanolubricants, hydration layers in biopolymers, manipulation of biomolecules, protein folding, stability of colloid suspensions, enzyme activity, swelling in clays, development of bioactive surfaces, water columns and ion channeling in membranes and scanning probe microscopy (SPM). It will also contribute to the improved performance of moving components in silicon-based micro-electro-mechanical system (MEMS) devices, where water plays a key role in interfacial interactions.

Nanotechnology is the creation of useful materials, devices, and systems through the control of matter on the nanometer-length scale. This takes place at the scale of atoms, molecules, and supramolecular structures. In the world of chemistry, the rational design of molecular structures and optimized control of self-assembly conditions have enabled us to control the resultant self-assembled morphologies having 1 to 100-nm dimensions with sing- nanometer precision. This current research trend applying the bottom-up approach to molecules remarkably contrasts with the top-down approach in nanotechnology, in which electronic devices are miniaturizing to smaller than 30 nm. However, even engineers working with state-of-the-art computer te- nology state that maintaining the rate of improvement based on Moore’s law will be the most dif?cult challenge in the next decade. On the other hand, the excellent properties and intelligent functions of a variety of natural materials have inspired polymer and organic chemists to tailor their synthetic organic alternatives by extracting the essential structural elements. In particular, one-dimensional structures in nature with sophis- cated hierarchy, such as myelinated axons in neurons, tendon, protein tubes of tubulin, and spider webs, provide intriguing examples of integrated functions and properties. Against this background, supramolecular self-assembly of one-dimensional architectures like ?bers and tubes from amphiphilic molecules, bio-related molecules, and properly designed self-assembling polymer molecules has - tracted rapidly growing interest.

This report examines seven disposal technologies being considered by the U.S. government as alternative methods to the process of incineration for destroying mortars, rockets, land mines, and other weapons that contain chemical warfare agents, such as mustard gas. These weapons are considered especially dangerous because they contain both chemical warfare agent and explosive materials in an assembled package that must be disassembled for destruction. The study identifies the strengths and weaknesses and advantages and disadvantages of each technology and assesses their potential for full-scale implementation.

At the end of the rotary, once the harness is inserted, assembled, and taped, it still needs one more operation (at least the one that we assembled in this particular factory): the installation of the grommet.

Established in 1659 as Misión de Nuestra Señora de Guadalupe de los Mansos del Paso del Norte, Ciudad Juárez is the oldest colonial settlement on the U.S.-Mexico border-and one of the largest industrialized border cities in the world. Since the days of its founding, Juárez has been marked by different forms of conquest and the quest for wealth as an elaborate matrix of gender, class, and ethnic hierarchies struggled for dominance. Juxtaposing the early Spanish invasions of the region with the arrival of late-twentieth-century industrial "conquistadors," Fragmented Lives, Assembled Parts documents the consequences of imperial history through in-depth ethnographic studies of working-class factory life. By comparing the social and human consequences of recent globalism with the region's pioneer era, Alejandro Lugo demonstrates the ways in which class mobilization is itself constantly being "unmade" at both the international and personal levels for border workers. Both an inside account of maquiladora practices and a rich social history, this is an interdisciplinary survey of the legacies, tropes, economic systems, and gender-based inequalities reflected in a unique cultural landscape. Through a framework of theoretical conceptualizations applied to a range of facets—from multiracial "mestizo" populations to the notions of border "crossings" and "inspections," as well as the recent brutal killings of working-class women in Ciudad Juárez—Fragmented Lives, Assembled Parts provides a critical understanding of the effect of transnational corporations on contemporary Mexico, calling for official recognition of the desperate need for improved working and living conditions within this community.

Based on the Book of Revelation, a science fiction military thriller. For a time, The Architect, an inventor and renaissance man, unites the world in peace under one global government. It was not to be. For his own vanity, he built a temple. A great pantheon to all the world's religions. Outraged by this heresy the empire crumbled as religious fervor and patriotism gave rise to a coalition against The Architect's iron rule. From humble beginnings a hero rises and must make his way to the Holy City for the final cataclysm, The Battle of Armageddon. Throughout the journey the signs of the Apocalypse are woven into the fabric of life on earth as ancient atrocities are fed by modern and futuristic weapons of war. August, our hero, must survive multiple battles, espionage, treachery, and genocidal psychopathic allies, with the help of our narrator. Will August preserve the empire or destroy it?
