The utilization of solar irradiation to supply energy or to initiate chemical reactions is already
an established idea. If a wide-band gap semiconductor like titanium dioxide (TiO2) is …

An overview of the various carbon structures with characteristic sizes in the nanoscale
region is presented, with special attention devoted to the structures and properties of …

The phase stability of nanocrystalline anatase and rutile was analyzed thermodynamically.
According to the present analysis, anatase becomes more stable than rutile when the …

By combining different allotropic forms of carbon at the nanoscale it is possible to fabricate
tailor made surfaces with unique properties. These novel materials have shown high …

Primitive meteorites contain a few parts per million (ppm) of pristine interstellar grains that
provide information on nuclear and chemical processes in stars. Their interstellar origin is …

MEMS devices are currently fabricated primarily in silicon because of the available surface
machining technology. A major problem with the Si-based MEMS technology is that Si has …

BECAUSE of the chemical inertness of alkanes, the introduction of functional groups into
them by oxidation has tended to require severe and thus unselective conditions. The …

DIAMONDS just 3–5 nm in diameter have recently been recovered from carbonaceous
residues of detonations1. They have also been found in meteorites2, nucleate …

Infrared spectroscopy of dense clouds in the CH stretch region - Methanol and ' ADS Classic is
now deprecated. It will be completely retired in October 2019. This page will automatically …

IN a continuation of our search for interstellar'needles' in the meteoritic'haystack'1, 2, we
have now identified graphite grains, 1–4 µm in diameter, in the Murchison C2 chondrite. The …
