In an anchor rod ( 1 ) for a synthetic resin adhesive anchor having a shaft ( 2 ) with a plurality of area segments ( 4 ) arranged in axial succession, the surface of which is low-friction with respect to synthetic resin mortar ( 6 ), areas ( 4 ) are formed. Viewed in a ...
All material deposited on the surface of the electrode that has a greater resistivity than the extracellular fluid will increase the impedance by decreasing the effective stimulation area of the electrode (see Chapter 8). The larger the effective surface area, the smaller the impedance. This means...
The Surface Structure of and Catalysis by Platinum Single Crystal Surfaces In the case of metal catalysts most commercial catalyst systems consist of finely dispersed metal particles that are deposited on a high surface area support, most frequently silica or alumina. Even at present the atomic struc...
3a), the main product is still the [A-Ag]n structures but with reduced chain lengths in comparison with the long [A-Ag]n chains obtained at r ~ 1. Fig. 3: Stoichiometry-dependent polymerization. Large-area STM images of the reaction products achieved by P-Br and A-H on Ag(111...

In subject area: Engineering Roughness and texture can come in many guises: surface asperities can be randomly rough or fractal, have uniform height but variable widths or uniform widths but variable heights, have a periodic pattern, and so on. ...
Q.How large an area do you test to get the value is of Ra? How do you separate Ra from flatness? Ian Barlow Engineer - France July 8, 2008 Q.I need to know what is measuring equipment to measure Ra? Zaki Yamani Ahmad engineer - Kuantan, Pahang, Malaysia ...
In this study, a new series of zinc oxide (ZnO) with high specific surface area and narrow energy band gap are prepared using a facile microwave-induced method. The corresponding formation mechanism is also discussed for the first time. Due to the introduction of C, these ZnO can be excited...
Previous work showed that if surface area synthesis, like volume synthesis, is dependent on cell volume (rather than surface area), SA/V will equilibrate at a steady-state value corresponding to the ratio of surface and volume synthesis rates23 (Fig. 2a). Here, “volume synthesis” is repre...
