Filed:

Jun 24, 2002

Appl. No.:

09/980493

Inventors:

Robert L. Mullen - Moreland Hills OH
Mehmet Ozgur - Cleveland OH
Gerhard E. Welsch - Cleveland Heights OH

Assignee:

Case Western Reserve University - Cleveland OH

International Classification:

B32B 704

US Classification:

4283139, 4283171, 4283215, 428403, 428593, 75230, 75232, 75243

Abstract:

A plurality of closed metal cells is provided. Each cell encapulates a fluid or a fluid-like filler with a metal skin or cell wall. The closed cells are joined into an aggregate arrangement to form a composite material in which the bonded cell walls form a continuous metal matrix. The cell walls and the encapulated cell filler fluid or fluid-like filler provide controllable stiffness and strength as well as vibration-damping and shock-absorbing characteristics to the material. The resulting closed cell metal composite finds many advantages uses including use as a prosthetic device, a casting, or an automotive component. The component material is elastically compliant or stiff, depending on the design, as well as lightweight and resistant to buckling and crushing. The material provides desirable physical properties such as heat-capacity, thermal and electrical conductivity, vibration-damping capacity, and shock-absorbing characteristics.

Abstract:

An oriented strand board for structural applications and a method of its production comprising elongated strands having aspect ratios greater than 2, the strands being derived from the outer shells of oil palm tree fronds formed as a bi-product of the harvest of oil palm fruit, such that the strand length is limited to about a meter, the strands being cut from the outer shell area of the fronds and at least the outer regions of the major faces of the board being substantially free of core material, the shell strands being combined with a heat settable binder material, the strands being formed by elongated blades moving relative to a frond length in planes generally aligned with a longitudinal direction of the frond length, the strands of the frond shells being arranged and being permanently bonded together such that they are predominately generally aligned with the structural direction of the board at least at the outer regions of the major faces of the board.

Appl. No.:

8/375243

Inventors:

Mehran Mehregany - Shaker Heights OH
Randal H. Rudderman - Norcross GA
Robert L. Mullen - Moreland Hills OH

Assignee:

MicroMed, Incorporated - Duluth GA

International Classification:

B26B 300
B25G 300

US Classification:

30342

Abstract:

A micromachined blade suitable for medical applications has an edge which is free of the imperfections common in mechanically sharpened steel blades. A method of forming micromachined blades having the desired characteristics may be performed by etching with anisotropic or isotropic etchants. This micromachined blade may be formed of a single-crystalline substrate, such as a silicon wafer commonly used in integrated circuit technology. Thus, such a micromachined blade may also carry circuitry capable of assisting a surgeon in the performance of certain procedures.

International Classification:

A61K 39/39

Abstract:

Chemical compositions and/or mixtures that allow nucleic acid to remain stable at ambient temperatures. The disclosed technology includes a solution and manufacturing methods thereof. The solution includes a chelating agent, a buffering agent, and a salt. The solution is configured to protect RNA and/or an RNA-based vaccine added to the solution and prevents or reduces degradation of the RNA and/or the RNA-based vaccine for a duration of 2 to 180 days over a temperature range of −20 degrees C. to +38 degrees C. The chelating agent can comprise ethylenediaminetetraacetic acid (EDTA). The buffering agent can comprise tris(hydroxymethyl)aminomethane (TRIS). The salt can comprise NaCl. The solution is configured to preserve an injectable mRNA vaccine added to the solution, and the solution is safe for injection into mammals.
