Photodiode quantum efficiency optimization using spherical pits on active surfaces
(Elsevier, 1995)
A numerical model of a photodiode with etched spherical pits on an active surface has been developed. Several geometrical parameters (radius of curvature, depth and arrangement of spherical pits, sample thickness and area, ...
The influence of protective atmosphere on oxidation of sintered SmCo5 magnetic materials
(ETRAN Society, 1996)
Understanding of the thermal stability of intermetallic SmCo5 powder is essential for designing the working atmosphere in all phases of the technological procedure in the production of sintered SmCo5 magnets to obtain ...
Nanoscale pattern formation during electrodeposition: Ru on reconstructed au(111)
(USA : American Physical Society, 1999)
Scanning tunneling microscopy results on Ru electrodeposition on reconstructed Au(111) are presented, which show a novel type of site-selective nucleation on this surface. At potentials around 0.0 V vs the Ag/AgCl reference ...
Surface morphology and the response of piezoelectric gas sensors
(Elsevier, 1995)
The surface morphology of gold electrodes on piezoelectric quartz crystals was characterized by scanning electron microscopy and scanning tunnelling microscopy. Sensors with various coating materials as polymers, liquid ...
Demineralization of an oil shale by Bacillus circulans (“siliceous bacteria”)
(Elsevier, 1990)
Experiments are presented aimed at removing the silicates from an oil shale by a chemoorganoheterotrophic bacterium, Bacillus circulans. This process was expected to substitute the drastic HF-treatment in the kerogen ...
Test of the validity of some kerogen models based on oxidative degradation
(Elsevier, 1990)
Molecular models of considerable complexity have been proposed recently for type I, II and III kerogens. Here, we describe the amount and type of carboxylic acids that one would expect to result from their multistep alkaline ...
Oxygen reduction on Au(111) and vicinal Au(332) faces: A rotating disc and disc-ring study
(Elsevier, 1994)
The kinetics of oxygen reduction on the Au(111) surface in acidic solution has been re-examined by means of a rotating disc electrode technique. Its vicinal Au(332) = Au[6(111) × (111)] surface has been chosen to examine ...
Standard potential values of "cyanide-sensitive" silver iodide and silver sulphide ion-selective electrodes
(Analytica Chimica Acta, 1990)
It is shown that the equation for the potentials of semiconductive sulphide membranes given by Sato 25 years ago is valid also for the calculation of E0 values of "cyanide-sensitive" ion-selective electrodes. The only ...
Kinetic and mechanistic study of methanol oxidation on a Pt(110) surface in alkaline media
(Elsevier, 1998)
The comparative study of methanol oxidation on a Pt(110) surface was carried out in bicarbonate, carbonate and sodium hydroxide solutions. It was shown that OH- electrosorption precedes the oxide layer formation in sodium ...
Corrosion rates and negative difference effects for Al and some Al alloys
(Springer, 1999)
The rotating disc-ring technique with a Pt ring was used to quantitatively detect hydrogen evolved on an Al-disc electrode during spontaneous corrosion at open-circuit potential or during anodic polarization of an Al disc ...
