Journal of Biomedical Materials Research. 42:266-271
RF magnetron sputter deposition was used to deposit thin calcium phosphate (hydroxyapatite) layers on titanium alloy substrate material. We determined the precise amount of calcium, phosphorus, oxygen, and hydrogen in these films by combining two ion

In many materials, the loss of hydrogen during elastic recoil detection (ERD) analysis and nuclear reaction analysis (NRA) with MeV ions is observed. This phenomenon, which is especially pronounced in organic materials, limits the accuracy of the qua

Surface passivation at low processing temperatures becomes an important topic for cheap solar cell processing. In this study, we first give a broad overview of the state of the art in this field. Subsequently, the results of a series of mutually rela

An 16 O 2 -oxidised Si(100) surface, covered with 15 nm Cu particles, was oxidised in 18 O 2 and subsequently reduced in H 2 . After reduction, there still was a significant amount of 18 O present in the sample. In this paper we concerned ourselves w

The oxidation of Cu particles supported on oxidised Si(100) by molecular oxygen was investigated by means of ellipsometry and Nuclear Reaction Analysis. Stepwise oxidation of a sample containing 15 nm Cu particles at 473 K and 0.1 Pa showed that the

Porphyrin organic dye layers on oxidic surfaces may play a key role in the light absorption and charge separation of organic solar cells. We report a study of the adsorption characteristics of positively charged porphyrins from an aqueous solution on

The Langmuir film-forming properties of rodlike oligo(cyclohexylidene) oximes and derivatives 1(n)-8 have been studied. It is shown that subtle structural modifications of their hydrocarbon framework, such as end-functionalization by a tert-butyl gro

Currently, medical and dental implants are often provided with thin calcium phosphate ceramic coatings (preferably Ca 5 (PO 4 ) 3 OH (HA)) to improve their biological behaviour. Previous studies have demonstrated that radio-frequency (r.f.) magnetron

The effects of discharge radiofrequency (RF) power and film thickness were studied on the characteristics of Ca5(PO4)3OH (hydroxyapatite) thin films fabricated by RF magnetron sputtering. The structure and chemical composition were investigated with

The deposition of a fourfold positively charged tetrakis(4-methyl pyridinium) porphyrin (H2TMPyP) and its metal derivatives on glass surfaces from basic aqueous solutions has been studied by optical and ion beam techniques. Upon exposure to a buffere
