An old question regarding the world we live in concerns what is real regarding points and lines: if two distinct lines intersect, is their intersection a unique point? In this paper, we take the approach that the answer is no, that all the points in

X-ray photoelectron spectroscopy (XPS), field emission scanning electron microscopy (FESEM), and open circuit potentials were used to compare the size, chemical state, and distribution of adsorbed and reduced gold from Au 31 chloride solution on pyri

We present a comparative treatment of two approaches to homomorphisms between affine spaces of dimensionn≥2 that leads to characterizations of homomorphisms of these geometries that preserve dimension and parallelism.

The reductive deposition of metallic Cu on porous silicon (PS) surface from aqueous solution of Cu{sup 2+}(aq) ions is reported. X-ray absorption near-edge structure (XANES) at the Cu L{sub 3,2} edge has been used to characterize these samples. It is

Using the x‐ray excited optical luminescence technique, we have investigated the soft x‐ray induced photoluminescence of porous silicon in the optical region (200–900 nm) and the Si K‐edge x‐ray absorption fine structures of porous silicon

FOLLOWING reports of intense optical luminescence from porous silicon1,2, the opportunity for engineering optoelectronic devices using this material3,4 has attracted considerable attention. At present, however, the question of the origin of the lumin
