Abstract

Metal matrix composites are a unique class of materials capable of circumventing the disadvantages of each category of materials they are composed of (polymers, metals, and ceramics). They can be designed using at least two categories of materials, harnessing their useful properties according to the designated end applications. In view of the compositional flexibility inherently associated with metal matrix composites, new materials with enhanced properties can be synthesized from practically all the metallic materials that are currently utilized in engineering and biomedical applications. This book, comprising 20 peer-reviewed papers, addresses the recent developments in the designing, processing, characterization, and potential applications of metal-based composites. The research articles cover composites based on light-weight materials (Al, Mg, and Ti) and other metal-based materials (Cu, Ag, and W), such as matrices and reinforcements from nano-length scales (such as ZnO, SiC, Y2O3, CNTs, Sm2O3, graphene oxide) to macro-length scales (such as tungsten fiber nets, saffil fibers etc.). The focus was placed almost equally on solid-state, liquid-state and two-phase synthesis techniques. Similarly, the elastic, mechanical, and thermal properties of the described composites are reported in detail. This compilation of papers will certainly be most useful for students, industrial professionals, and academics interested in learning and expanding their knowledge on metal-based composites.

Abstract

Lignocellulosic biomass has great potentials as an alternative feedstock for fuels and chemicals. For effective utilization of biomass, biomass recalcitrance, which is inherent resistance of plant cell walls to biological deconstruction, needs to be reduced. Among many factors in biomass, lignin is significantly related to biomass recalcitrance. Lignin, a complex aromatic polymer, is the largest non-carbohydrate component (15-40% dry weight) in most terrestrial plants. In nature, it provides a structural integrity, facilitates water and nutrient transport, and protects plants from microbial attack. From a different angle, lignin significantly contributes to biomass recalcitrance, so it is necessary to reduce and/or modify the lignin for effective conversion of biomass. Genetic modifications of the lignin biosynthetic pathway and lignin-targeting pretreatments have been developed to minimize the lignin-induced biomass recalcitrance. High carbon content of lignin also renders it an attractive feedstock for many applications. About 100,000 to 200,000 tons of lignin can be generated per year as a byproduct from cellulosic ethanol production, so valorization of these lignins could be one of keys for achieving economic biorefinery. However, investigations of lignin conversion have not been accomplished as the utilization of carbohydrates in biomass. Depolymerization of lignin is still challenging because of its broad distribution of bond strengths, recondensation of low-molecular species, and poor product selectivity. Diverse biological and thermochemical depolymerization methods have been investigated to overcome these barriers. In this Research Topic, recent advancements in biomass recalcitrance by effective utilization of lignin are introduced.

Abstract

This Special Issue cooperates with the 5th Asian Symposium on Emulsion Polymerization and Functional Polymeric Microspheres (ASEPFPM 2015) (http://asepfpm5.csp.escience.cn). Polymeric microspheres are basic materials for recent progress in environmental science, architecture, biomedicine, electronics, food, cosmetics, etc. While much progress has been made over the past few decades, there are still big challenges for the preparation of functional particles and the verification of preparation mechanisms; there is much room for growth in our ability to provide for high performance in these areas. The general theme of this symposium is to discuss recent advances in both fundamentals and applications, as well as to promote science and industrialization translation.

Abstract

Two-dimensional (2D) materials and their vertical/lateral heterostructures are currently the subject of massive research interests, both for fundamental science and for technological applications in diverse fields, such as electronics, optoelectronics, quantum metrology, spintronics, membranes, energy conversion/storage, and sensing. Integration of 2D materials within real device structures currently represents the main challenge to move from the laboratory stage to industrial applications, especially in the fields of electronics/optoelectronics.This Book is a collection of 9 papers, covering the different key topics of this rapidly developing research field. These include: synthesis of 2D materials, progress in relevant processing issues (contact, doping and mobility engineering), advanced characterization techniques, novel device applications based on the integration of these 2D materials.Many of the papers of this collection are review papers, providing the general introductory information and a broad overview of the most recent advances in the specific topic. Hence, this book can serve both as a general introduction for non-experts in the field and as a guide for scientists/engineers working in the field of 2D materials integration.

This open access book brings out the state of the art on how informatics-based tools are used and expected to be used in nanomaterials research. There has been great progress in the area in which “big-data” generated by experiments or computations are fully utilized to accelerate discovery of new materials, key factors, and design rules. Data-intensive approaches play indispensable roles in advanced materials characterization. "Materials informatics" is the central paradigm in the new trend. "Nanoinformatics" is its essential subset, which focuses on nanostructures of materials such as surfaces, interfaces, dopants, and point defects, playing a critical role in determining materials properties. There have been significant advances in experimental and computational techniques to characterize individual atoms in nanostructures and to gain quantitative information. The collaboration of researchers in materials science and information science is growing actively and is creating a new trend in materials science and engineering.

Abstract

The employment of printing techniques as cost-effective methods to fabricate low cost,&#xD;flexible, disposable and sustainable solar cells is intimately dependent on the substrate&#xD;properties and the adequate electronic devices to be powered by them. Among such&#xD;devices, there is currently a growing interest in the development of user-oriented and&#xD;multipurpose systems for intelligent packaging or on-site medical diagnostics, which&#xD;would greatly benefit from printable solar cells as their energy source for autonomous&#xD;operation.&#xD;This chapter first describes and analyzes different types of cellulose-based substrates for&#xD;flexible and cost effective optoelectronic and bio devices to be powered by printed solar&#xD;cells. Cellulose is one of the most promising platforms for green recyclable electronics&#xD;and it is fully compatible with large-scale printing techniques, although some critical&#xD;requirements must be addressed. Paper substrates exist in many forms. From common&#xD;office paper, to packaging cardboard used in the food industry, or nanoscale engineered&#xD;cellulose (e.g. bacterial cellulose). However, it is the structure and content of paper that&#xD;determines its end use. Secondly, proof-of-concept of optoelectronic and bio devices produced&#xD;by inkjet printing are described and show the usefulness of solar cells as a power&#xD;source or as a chemical reaction initiator for sensors.
