The Santa Monica Mountains are home to many species of chaparral shrubs that provide vegetative cover and whose deep roots contribute to the stability of the steep slopes. Recently, native chaparral have been threatened by an unprecedented drought an

Thin films of amorphous/polycrystalline Ti layers alternating with amorphous Si have been grown on room‐temperature {001} Si substrates by electron beam evaporation. Cross‐section transmission electron microscopy of these films indicates that the

The melting behavior of modulated Pb-Ge foils has been investigated by differential scanning calorimetry and x-ray diffraction. As the Pb layer thickness decreases, the melting temperature is depressed and broadened. For a 20-\AA{}-thick Pb film, the

We summarize the development of a high-resolution facsimile printing system in which miniature archival images are machined in metal film by a pulsed, focused, scanning laser beam The film is designed to machine at optical energies within the pulse-p

The effect of preferred orientation on the Hall effect in titanium was examined in an attempt to resolve the inconsistent results of previous investigators. Three specimens of iodide titanium were prepared with different textures and the Hall coeffic

By rapid quenching from the melt, solid solutions having the NaCl-type structure can be obtained between binaries of NbC, TaC, WC, and MoC. The superconducting transition temperatures of these pseudobinaries were investigated. The experimental result

An x‐ray diffractometer operating in vacuum has been designed and constructed to study metals sensitive to oxygen and nitrogen contamination at elevated temperature. The instrument operates in a vacuum of 2×10−6 mm Hg in which the partial pressu
