  • The importance of particle characterization in both the research and development, and the manufacture and quality control of materials and products that we use in our everyday lives is, in some sense, invisible to those of us not directly involved with these activities. Few of us know how particle size, shape, or surface characteristics can influence, for example, the efficacy of a painreliever, or the efficiency of a catalytic converter, or the resolution of a printer.

  • The invention of scanning tunneling microscope (STM) by Binnig and his colleagues in 1982 opened up the possibility of imaging material surfaces with spatial resolution much superior to the conventional microscopy techniques. The STM is the first instrument capable of directly obtaining three-dimensional images of solid surfaces with atomic resolution. Even though STM is capable of achieving atomic resolution, it can only be used on electrical conductors. This limitation has led to the invention of atomic force microscope (AFM) by Binnig and his co-workers in 1986.

  • Within a period of a few decades, the ¯eld of materials science and engineering has emerged as a focal point for developments in virtually all areas of engineering and applied science. The study of thin film materials has been one of the unifying themes in the development of the ¯eld during this period. As understood here, the area encompasses ¯lms bonded to relatively thick substrates, multilayer materials, patterned ¯lms on substrates and free-standing ¯lms.

  • The first edition of the Handbook of Micro/Nanotribology was published in the Spring of 1995. Soon after its publication, the first-of-a-kind monograph became a reference book for the novice, as well as experts, in the emerging field of micro/nanotribology. Since the field is evolving very rapidly, we felt that the monograph needed a second edition. The second edition is totally revised. The scope of the first edition has been expanded. In the first part, Basic Studies, two new chapters on AFM Instrumentation and Tips and Surface Forces and Adhesion have been added.

  • The coatings present a compact structure, without any visible delaminations or defects. The morphology of the fracture of coatings is characterized by a dense structure, in some cases there is a columnar structure (Figs. 1, 2, 3). The fracture surface of the steel samples was examined and the deposited coatings show a sharp transition zone between the substrate and the coating.

  • Where the possibilities of a man reached the end, especially from the point of view of technical solutions, the nature took over and formed our environment according to its needs. Nowadays technical and engineering activities have a significantly greater impact on the natural laws and rules once considered as changeless. Nonetheless we have been approaching the same pattern that we followed in the past – we get inspired by the nature.

  • Over the past few decades numerous studies have shown an alarming increase in the concentration of atmospheric particular matter called aerosols resulting from a variety of human activities, ranging from agricultural to combustion of fossil fuels. Besides having serious impacts on the health of all living creatures, these particles can affect planetary radiation budget. Consequences of this change include global temperature shifts and the altering of atmospheric and oceanic circulation patterns.

  • The effects of micronization methods, mechanical and jet millings, on the physico-chemical properties of mushroom (Lentinus edodes) powder were investigated in contrast to shear pulverization. The powders of dried mushroom cap and stipe were prepared to obtain six powders. Compared to shear pulverization, mechanical and jet millings effectively reduced particle size and brought about a narrow and uniform particle size distribution.

  • Polymer applications have become more demanding as industry continuously turns to more microscopic parts. Due to the interactions of the polymer chains with the supporting surface and the air interface, the thinner films required for such applications have distinctly different properties than those of the well-defined bulk systems. The goal of the current research is to elucidate the behavior of ultrathin films.

  • Intensity of use of freshwater resources (both surface and groundwater) is expressed as gross abstractions per capita, as a percentage of total available renewable freshwater resources, including inflows from neighbouring countries (see below) and as a percentage of internal resources. It has to be noted that when measured at national level these indicators may hide significant variations at territorial level. Wastewater treatment connection rates show the percentage of the national population actually connected to public waste water treatment plants.

  • Porcine reproductive and respiratory syndrome (PRRS) is one of the most significant swine diseases worldwide. Despite its relevance, serum biomarkers associated with early-onset viral infection, when clinical signs are not detectable and the disease is characterized by a weak anti-viral response and persistent infection, have not yet been identified. Surface-enhanced laser desorption ionization time of flight mass spectrometry (SELDI-TOF MS) is a reproducible, accurate, and simple method for the identification of biomarker proteins related to disease in serum.
