  • Scientists who dedicate their research activity to biomaterials pass through the typical dichotomy that often characterizes the basic research. On one side is the wish of exploring new frontiers of chemistry, physics, biology, medicine, pharmaceutics and all other disciplines to which biomaterials can be applied. Constantly improving of scientific knowledge would feed the freedom of attempting new strategies for producing materials with always tailored and improved characteristics.

  • This book contains chapters on nanocomposites for engineering hard materials for high performance aircraft, rocket and automobile use, using laser pulses to form metal coatings on glass and quartz, and also tungsten carbide-cobalt nanoparticles using high voltage discharges. A major section of this book is largely devoted to chapters outlining and applying analytic methods needed for studies of nanocomposites. As such, this book will serve as good resource for such analytic methods.

  • 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.

  • In 1665, a book was published that inaugurated the use of the microscope to investigate the natural world. The author was Robert Hooke, a talented artist, architect, and amateur scientist. Hooke wrote Micrographia: Or Some Physiological Descriptions of Minute Bodies Made by Magnifying Glasses with Observations and Inquiries Thereupon, at the behest of the newly chartered Royal Society in London, for whom he was working as curator of scientific experiments. In Micrographia, he presented the first detailed observations of everyday objects made with his self-constructed light microscope....

  • Sliding glass doors are easy for a burglar to enter if no remedial action is taken. Often, the door panels can simply be lifted out of the tracks. To solve this problem, open the active door and install a few screws in the track, allowing the screw to project down 3/8" to 1/2". Use a stack of several metal washers to serve as a spacer so the screws can be firmly set. Slide the door closed, making sure the extended screws pass freely over the top rail of the door. Now try to lift the door from the track; upward movement should be stopped by the...

  • Horizontal sliding windows should be treated much the same as sliding glass doors. Header stops in the form of screws with metal washer stacks can be used to remove the space between the top rail of the sash and the track in a way that prevents the sash from being lifted from the track. Once this has been accomplished, a length of wood dowel or special blocking lock bar can be installed on the window to prevent the window from sliding. In some cases, both window sashes slide independently. The outer most sash should be fixed in the track by screws and/or brackets.

  • Composite is a material composed of two or more component materials to obtain better properties. 3-phase composite is usually added with reinforced fibers and particles. This report presents an experimental study on the bending of some 3-phase composite plates for Vietnam’s shipbuilding industry. The studied composite is made of polyester matrix, glass fiber and titanium dioxide particle (TiO2). The numerical study, in which the interaction between the matrix and particle is taken into account, shows good agreement with the experiment. ...

  • It is less than five years since the last edition of Modern Physical Metallurgy was enlarged to include the related subject of Materials Science and Engineering, appearing under the title Metals and Materials: Science, Processes, Applications. In its revised approach, it covered a wider range of metals and alloys and included ceramics and glasses, polymers and composites, modern alloys and surface engineering.

  • Automatic sampler (optional)—The sampler must incorporate glass sample containers for the collection of a minimum of 250 mL of sample. Sample containers must be kept refrigerated at 4°C and protected from light during compositing. If the sampler uses a peristaltic pump, a minimum length of compressible silicone rubber tubing may be used. Before use, however, the compressible tubing should be thoroughly rinsed with methanol, followed by repeated rinsings with distilled water to minimize the potential for contamination of the sample.

  • The preparation and mechanical properties of bamboo - glass fiber mat reinforced polyropylene hybrid composite (BGMRPC) were investigated. The results showed that properies of the composite depend on the amount of glass fiber mat and the hybrid method. Replacing 13.5% of bamboo fiber mat by glass fiber mat, the tensile, flexural and impact strengths of BGMRPC were increased by 33%, 28% and 79% respectively comparing to bamboo fiber mat reinforced polypropylene composite (BMRPC). The moisture absorption of BMRPC and BGMRPC was studied and compared.
