In his research commentary, Leggett discusses two reports in the same issue: One, by Anderson, describes how his interlayer tunneling theory compares with recent experimental data in three materials, and the other, by Moler et al., presents new data on one of the three materials.
We describe here the use of two-dimensional heart-cut LC-LC in combination with exact-matching double isotope dilution mass spectrometry to determine the content of aflatoxin B1 in three materials used in a proficiency testing scheme.
In one material (the negative, or n-type, semiconductor) the charge carriers are electrons, and in the other (the positive, or p-type, semiconductor) the charge carriers are "holes" created by the absence of electrons.
Tensile tests were performed at the maximum service temperature on aged samples in two material directions to evaluate the progression of stiffness and Ultimate Tensile Strength (UTS) degradation.
Do not buy all sizes and lengths of needles in one material before you know whether or not you like working with that material.
They come with three sizes of wing and three different sizes of earbud in two materials, but I found the smallest wings to completely fill my outer ear.

A thirty-six-foot square of metal plates in six materials — aluminum, steel, copper, zinc, lead, magnesium — it was Andre's largest sculpture so far, and what he called his "erotic relationship with materials" came through in the subtle play of colors, surface textures, tonalities, mass, weight, and reflected light across the checkerboard of twelve hundred and ninety-six interacting elements.
