We present a lightweight mirror made of a magnesium alloy for appliions to space-borne telescopes and optics in instruments. A non-flammable magnesium alloy was recently developed. We consider this alloy to be a promising material for a lightweight mirror due to its high stiffness, high fracture toughness, low density, and suitability for machining.
Magnesium is very well tolerated by the body and has a natural tendency for degradation. In addition, its low elastic modulus helps to reduce stress-shielding effect during bone healing. Mg- Ca alloys are particularly of interest for the additional processing and property benefits that Ca addition provides.

In this report we describe an experimental approach for depositing self-asseled mono/multilayers (SAMs) of octadecylphosphonic acid (ODPA) on the native oxide layer of magnesium alloy. These layers were characterized using Fourier transform infrared spectroscopy (FTIR), X-ray photoelectron spectroscopy (XPS), atomic force microscopy (AFM) and contact angle measurements (CA).

The newly developed LX41 alloy also exhibited a reasonably good cytocompatibility [S.S. Nene et al., Bionanomaterials, DOI: 10.1515/bnm-2015-0019]. A result that should allay possible concerns about toxicity of Li is that the concentration of Li + ions released from an LX41 specimen into the surrounding simulated body fluid was below the accepted level.
