Modern hunting apparel is emblazoned with bright orange, but this mid-20th century vest isn't brightly colored. We wonder if it was open season on hunters 50 years ago.
Al 96, Cu 4 (wt%), solution treated and overaged - precipitation hardening
This sample has been aged after quenching to enable the growth of precipitates from a supersaturated solid solution. The strength of the alloy has been greatly improved by precipitation hardening. A precipitation sequence is observed eventually resulting in the formation of the stable θ phase through a series of metastable intermediates. The θ phase is an intermetallic compound with a composition close to CuAl2. The θ precipitates preferentially form on Al grain boundaries, as these are excel

Smart Materials for Architecture and Renewable Energy
The rapid developments in molecular sciences like nanotechnology, self-organizing molecular systems and biomaterials generate a wealth of new materials and functions. In comparison to electronics and medical sciences, the application of these new materials in architecture and civil engineering remains somewhat underexposed. It is our opinion that new functionalities in optics, responsive mechanics, sensing and adjustable permeation for gases and water might add to new opportunities in providing
The Reading Game
there are 44 lessons with 1100 questions leading to learning 55 words, the first 55 words that reading courses teach. A report card follows every lesson to track progress. If the student gets ten percent more wrong, then you need to check on the student for he may need support.
