Sulfurized Passivation of GaAs(100) Surfaces
We have developed a new electrochemical passivation method to obtain a quite stable sulfide layer on GaAs surface. This layer is very thick and contains a mixture of Ga, As, S, O and H compounds. The photolumi...

Formation and Electronic Structure of the Mn/GaAs(100) Interface
Formation and electronic structure of the Mn/GaAs(100) interface grown at room temperature are studied by photoemission. The growth at early stage is identified to be in two-dimensional mode. The chemical reac...

Epitasxial Growth of ZnSe on S-Passivated GaAs (100) Substrate
A new sulfur passivation technique for GaAs surface by using S2Cl2 instead of (NH4)2Sx has been developed. Auger electron spectroscopy verifies the passivated surface is almost completely free of oxygen. The resu...

Nitric oxide synthase in the enteric nervous system of the guinea-pig: a quantitative description
The distribution and abundance of nitric oxide synthase (NOS)-containing neurons and their terminals in the gastrointestinal tract of the guinea-pig were examined in detail using NADPH diaphorase histochemistr...

Modelling of Multi-Ion-Beam Reactive Cosputtering for Metal Oxide Thin Films
Very recently a new technique named multi-ion-bram reactive cosputtering(MIBRECS) was developed for preparing multi-component metal oxide thin films. Epitaxial or highly oriented (Pb,La) TiO3 thin films sputtered...

Do vasoactive intestinal peptide (VIP)-and nitric oxide synthase-immunoreactive terminals synapse exclusively with VIP cell bodies in the submucous plexus of the guinea-pig ileum?
In the submucous plexus of the guinea-pig ileum, previous light-microscopic studies have revealed that vasoactive intestinal peptide (VIP)-immunoreactive and nitric oxide synthase (NOS)-immunoreactive terminal...

Transthyretin distribution in the develo** choroid plexus of the South American opossum (Monodelphis domestica)
The distributions of transthyretin and albumin in the choroid plexus during brain development have been compared. The South American opossum was chosen because the young are born around the time of choroid ple...

Immunohistochemical localisation of cholinergic markers in putative intrinsic primary afferent neurons of the guinea-pig small intestine
Antibodies against choline acetyltransferase (ChAT) and the vesicular acetylcholine transporter (VAChT) were used to determine whether neurons that have previously been identified as intrinsic primary afferent...

The FERRUM project: radiative lifetimes of intermediate-excitation states of Fe II measured in a fluorescence signal induced by laser pum** from a metastable state
A new collaborative program, the FERRUM project, aims at extending and improving the database of oscillator strengths for the astrophysical important Fe II spectrum. In this paper we report on the experimental...

Inputs from intrinsic primary afferent neurons to nitric oxide synthase-immunoreactive neurons in the myenteric plexus of guinea pig ileum
Nitric oxide synthase (NOS) immunoreactivity occurs in two groups of neurons in the guinea pig small intestine: descending interneurons that are also immunoreactive for choline acetyltransferase (ChAT), and in...

Lifetime measurements in Gd II and Gd III using time-resolved laser spectroscopy
Natural radiative lifetimes of 20 levels (energy range between 29 000-35 000 cm-1) in Gd II and 5 levels (energy range between 43 000-49 000 cm-1) in Gd III have been measured using time-resolved laser-induced fl...

Two-color pump-probe experiments in helium using high-order harmonics
A pump-probe technique has been applied for measuring the lifetimes and absolute photoionization cross-sections of excited He states. The 1s2p 1P and 1s3p 1P states of He are excited by using the 13th and the 14t...
