The invention is directed to chalcogenide glasses suitable for use in plastics forming processes. The glasses have the general formula YZ, where Y is Ge, As, Sb or a mixture of two or more of the sane; Z is Se, Te, or a mixture of Se+Te; and Y and Z are present in amounts (in atomic/element percent) in the range of Y=15-70% and Z=30-85%. The chalcogenide glasses of the invention have a 10,000 poise temperature of 400&#xb0; C. and are resistant to crystallization when processed at high shear rates at their 10,000 poise temperature. The glasses can be used to make, among other items, molded telecommunication elements, lenses and infrared sensing devices.

A microplate is described that has a surface with an enhanced lubricious property which makes it easier to remove the microplate from a thermocycler. Basically, the microplate has a frame which includes an array of wells formed therein that are made from a thermoplastic material (e.g. polypropylene) mixed with a non-toxic surface active material (e.g., surfactant, stearyl alcohol). The non-toxic surface active material functions to enhance the lubricity of the surface of the microplate which makes it easier to remove the microplate from the thermocycler. In addition, the non-toxic surface active material within the microplate also makes it easier to remove a newly molded microplate from a mold cavity in an injection molding machine. Also described herein are details about methods for making and using such microplates.

A method of extruding an electrode, batch material, particularly a zinc or nickel, electrode material, and an extruder assembly for extruding the material, are described. The method and extruder are designed to produce a low compaction of the material and low, back pressure, whereby working of the batch material is limited.
