Hybrid composite laminates are manufactured by using technologies and raw materials of the aeronautic sector with aim to improve damping behavior structures. Matrix hybridization was achieved laminating carbon fiber reinforced (CFR) plies elastomer interlayers. Up 10 different sandwich architectures were investigated changing stacking sequence, thickness layers, typology, whereas total number C...

There is a large demand for fabrics that can survive high-temperature fires for an extended period of time, and protect the skin from burn injuries. Even though fire-resistant polymer fabrics are commercially available, many of these fabrics are expensive, decompose rapidly, and/or become very hot when exposed to high temperatures. We have developed a new class of fire-retarding materials by la...

The ability to make a socket by applying a thermoplastic material such as Polysar X-414 (Polymer Corp. Ltd. TM) directly to an amputee's stump o...

A Syme amputation, which is the most conservative below-the-knee amputation and which provides the best functioning stump for weight-bearing, has been rarely recommended for women, because the unsightly prosthesis is objectionable. Some time ago it was necessary to amputate the foot of a female patient, twenty-two years old. After a conference with the young woman, it was decided that the many ...

The inhomogeneous Li electrodeposition of lithium metal electrode has been a major impediment to the realization of rechargeable lithium metal batteries. Although single ion conducting ionomers can induce more homogeneous Li electrodeposition by preventing Li(+) depletion at Li surface, currently available materials do not allow room-temperature operation due to their low room temperature condu...

A flexible amperometric glucose sensor formed on biocompatible polymer was fabricated and tested. The sensor was fabricated by laminating biocompatible polymers and film electrodes. Functional and biocompatible polymers of polydimethyl siloxane (PDMS) and 2-methacryloyloxyethyl phosphorylcholine (MPC) copolymerized with dodecyl methacrylate (DMA) were utilized as the sensor material. Particular...

There is an unmet need for high-throughput fabrication techniques for paper-based microanalytical devices, especially in limited resource areas. Fabrication of these devices requires precise and repeatable deposition of hydrophobic materials in a defined pattern to delineate the hydrophilic reaction zones. In this study, we demonstrated a cost- and time-effective method for high-throughput, eas...

A long flexible material called the web is converted into final product through various processes such as printing, drying, coating, and laminating using a handling system. The transported from an unwind roller to rewind some guide drive rollers in servo motors control regulate their rotation velocity or torque system, where tension transportation controls play important role achieving high qua...

Hevea brasiliensis is a very prominent species in Brazil, but there are few studies correlating this with wood panels production. Based on this, the aim of work was to evaluate technical feasibility laminating and plywood production varying weight solids content glue mixture mechanical properties. Phenolic five 2.0 thick veneers produced laboratory, two different contents mixture: 35 40%, three...
