  • Investigation of the magnetic properties of materials is very important, because magnetic phenomena have various scientific and technical applications. The macroscopic properties of matter are a manifestation of the microscopic properties of the atoms of which it is composed. The magnetic properties of materials may be very different for types of material, depending on their nature and structure.

  • The title of this standard should not be taken to imply that all of the materials quoted are necessarily used solely or even principally in building. This schedule was first published in 1935 as an attempt to provide a solution to the problems which had arisen through structural and other calculations being based on different data for the weights of materials concerned. The 1949 revision was undertaken with a view to making the information more complete by the inclusion of certain extra materials, together with such changes in the data as had been found to be necessary....

  • A biosensor is a detecting device that combines a transducer with a biologically sensitive and selective component. Biosensors can measure compounds present in the environment, chemical processes, food and human body at low cost if compared with traditional analytical techniques. This book covers a wide range of aspects and issues related to biosensor technology, bringing together researchers from 19 different countries.

  • In the past several years, there have been many developments in the materials for lead–acid batteries. Silver in grid alloys for high temperature climates in SLI batteries has increased the silver content of the recycled lead stream. Concern about silver and other contaminants in lead for the active material for VRLA batteries led to the initiation of a study by ALABC at CSIRO. The study evaluated the effects of many different impurities on the hydrogen and oxygen evolution currents in float service for flooded and VRLA batteries at different temperatures and potentials. ...

  • Common engineering materials reach in many engineering applications such as automotive or aerospace; their limits and new developments are required to fulfill increasing demands on performance and characteristics. The properties of mate- rials can be increased, for example, by combining different materials to achieve better properties than a single constituent or by shaping the material or constituents in a specific structure. Many of these new materials reveal a much more complex behavior than traditional engineering materials due to their advanced structure or composition.

  • Following are writing samples that have been annotated to illustrate the criteria required to meet the Common Core State Standards for particular types of writing—argument, informative/explanatory text, and narrative—in a given grade. Each of the samples exhibits at least the level of quality required to meet the Writing standards for that grade. The range of accomplishment within each grade reflects differences in individual development as well as in the conditions under which the student writers were expected to work.

  • Normally, any ferromagnetic or ferrimagnetic material undergoes a transition to a paramagnetic state above its Curie temperature. Superparamagnetism is different from this standard transition since it occurs below the Curie temperature of the material. Superparamagnetism occurs in nanoparticles which are single domain. This is possible when their diameter is below 3–50 nm, depending on the materials.

  • The Essays in this volume, as will be apparent, have all of them had an occasional origin. They bear evident traces of particular controversy and contain much criticism of authors who are hardly, if at all, known in this country. Their author thought it worth while to collect them in one volume and it has been, I am sure, worth while to have them translated into English, because though written on different occasions and in different controversies they have all the same purpose. They are an attempt to make clear by philosophical criticism the real purpose and value of Marx's work....

  • This book is the first monograph on the theme of “new materialism,” an emerging trend in 21st century thought that has already left its mark in such fields as philosophy, cultural theory, feminism, science studies, and the arts. The first part of the book contains elaborate interviews with some of the most prominent new materialist scholars of today: Rosi Braidotti, Manuel DeLanda, Karen Barad, and Quentin Meillassoux.

  • This paper presents the result of research on equipment development of vacuum injection molding technique for preparation the chopped bamboo fiber polymer composite and some properties of obtained composite material. For the vacuum injection molding technique, firstly the dry fibers were plated in the mold. Then the mold was closed by the vacuum bag, the air inside the mold was sucked out by a vacuum pump, due to the difference of the pressure in side and outside the mold, the polymer liquid was transferred to the closed mold and impregnated the bamboo fiber.

  • Fe-SBA-15 and Fe-SBA-16 ordered mesoporous materials were synthesized via hydrothermal treatment by in situ incorporating Fe(III) oxalate complex species into framework of SBA-15 and SBA-16. The prepared samples were characterized by different techniques such as XRD, BET, UV- Vis and TEM. The obtained results showed that both Fe-SBA-15 and Fe-SBA-16 samples have an ordered mesoporous structure. The hexagonal symmetry of Fe-SBA-15 and cubic ones of Fe-SBA- 16 were not affected by incorporation of Fe into SBA-15 and SBA-16 frameworks.
