Bulk graphite: materials and manufacturing process

Thermal Rectification Using Bulk Materials

In conduction, thermal rectification occurs when a material or structure transfers heat asymmetrically. In this work, it is shown that, in the bulk, the necessary condition for thermal rectification is that the thermal conductivity of the material or structure be a function of both space and temperature, and that this function is not separable. Practically, this can be achieved using a composit...

Bulk Behavior of Nanostructured Materials

Observational Models of Graphite Pencil Materials

This paper presents models for graphite pencil, drawing paper, blenders, and kneaded eraser that produce realistic looking pencil marks, textures, and tones. Our models are based on an observation of how lead pencils interact with drawing paper, and on the absorptive and dispersive properties of blenders and erasers interacting with lead material deposited over drawing paper. The models conside...

Rapid Manufacturing of Digital Materials

The transition from analog to digital has revolutionized many fields over the past century – most notably computation and communication – and can be used to similarly revolutionize additive manufacturing technology. Digital materials are composed of many discrete, self-aligning voxels placed in a massively parallel layer deposition process, as opposed to continuous (analog) deposition technique...

Progress and improvement of the manufacturing process of snake antivenom

Antivenoms have been used successfully for more than a century and up to now constitute the only effective treatment for snakebites .The production of antivenin started long time ago when the calmette was prepared the antivenom in 1894.The method currently used to prepare antivenom by most of the manufacturers are originated from the method of Pope which was develop in 1938. Several new approac...
