Bulk solidifying amorphous alloys (BMGs) having improved corrosion resistance properties; and more particularly a sub-set of Zr—Ti-based BMGs having improved corrosion resistance properties are provided. The BMG compositions are formed by carefully controlling the concentration of, or removing altogether, highly electronegative elements, such as Ni and Cu from Zr—Ti-based bulk solidifying amorphous alloys thereby producing BMG materials with corrosion resistance properties that far exceed those of current commercially available BMGs and most conventional alloys. The elimination of these electronegative materials also opens the possibility of new uses for BMGs, including in biological applications.

The invention is directed to Pd-based metallic glass alloys useful in biomedical applications having no Ni or Cu. Exemplary metallic glass alloys are represented by AB{(Si)(D)}, where A may be selected from Pd, and combinations of Pd and Pt, B may be selected from Ag, Au, Co, Fe, and combinations thereof, and D may be selected from P, Ge, B, S. Also, a, b, c and d are atomic percentages, and a ranges from about 60 to about 90, b ranges from about 2 to about 18, d ranges from about 5 to about 25, and c is greater than 0 and less than 100.

Low density Be-bearing bulk amorphous structural alloys with more than double the specific strength of conventional titanium alloys and methods of forming bulk articles from such alloys having thicknesses greater than 0. 5 mm are provided. The bulk solidifying amorphous alloys described exclude late transition metal components while still exhibiting good glass forming ability, exceptional thermal stability, and high strength.

High strength, thermoplastically processable (TPF) amorphous alloys composed of Beryllium and at least one ETM and at least one LTM, as well as methods of processing such alloys are provided. The TPF alloys of the invention demonstrate good glass forming ability, low viscosity in the supercooled liquid region (SCLR), a low processing temperature, and a long processing time at that temperature before crystallization.

Novel cellular solids and foams from amorphous materials with a glass transition temperature (T) and methods of forming such materials are provided. In particular, foams are formed by expanding or compressing hollow spheres made of a high strength amorphous material, which is defined as a material having high strength characteristics, but also possessing a glass transition within a confined space. Using such a method, it has been unexpectedly found that it is possible to make cellular structures, including both open and closed cell foams, with customizable properties from materials that have been inaccessible with conventional methods. Moreover, based on calculations high specific strengths and stiffnesses are expected.

A low energy fluid purification system and method of implementation including some embodiments having a vacuum-rated first chamber placed in or near a body of water with higher temperature near the surface and lower temperatures at greater depths. The vacuum-rated first chamber holds a quantity of non-potable water and a low pressure area less than or equal to the water's vapor pressure. Vaporization occurs when the higher temperature surface water is brought into contact with the low pressure area. A tubular vapor transport passage allows the vaporized water to pass to a lower temperature and lower pressure condensation chamber. The lower temperature condensation chamber is cooled by lower temperature water from a selected depth below the surface. As the temperature of the vapor lowers, the vapor will condense. This condensation is collected as a quantity of potable water. Additional embodiments and methods are also provided.
