The intensity of solar energy is an important factor in viewing the performance thermoelectric generator (TEG). Most studies only look at effect treatment on TEG module form cooling mode and its materials. Therefore this study examines value magnitude voltage. On hot side are placed heat absorber plates copper, Fe aluminum as well non collector plates. Modules cascaded connected series many 14 ...

the effect of steel plate thickness on the repair effectiveness of rc beam is presented in this paper. a total of four beams were tested, one beam repaired by cfrp with a thickness of 1.2 mm and used as a control beam, and three beams repaired by a steel plate. steel plates with a thickness of 2 mm, 3 mm, and 4 mm were used in repairing the beams. the maximum load-carrying capacity, deflection ...

Abstract Air-cooled copper-aluminum composite heat sink is generally used for dissipation of electronic components. If the traditional connection mode used, such as welding, copper plugging and locking, bad phenomena pores, impurities interface thermal resistance easily occur on bonding surface, resulting in decreased conduction efficiency, efficiency lower strength surface. Therefore, we intro...

Abstract So-called “plate slags” from the archaeological Bronze Age copper smelting site Acqua Fredda were examined. What was common to all examined slags that their compositions, once converted and plotted on FeO-SiO 2 -CaO phase diagram, located at boundary between olivine wollastonite, resulting in melting temperatures of approx. 1100 °C for slags. Slags with a composition which fall within ...

Recently, amorphous alloys have attracted many researchers' attention for amorphous structures and excellent properties. However, the welding of amorphous alloys to traditional metals in the microscale is not easy to realize in the process with amorphous structures unchanged, which restrains the application in industry. In this paper, a new method of welding Fe-based amorphous alloys (GB1K101) ...

The baseline toroidal field coil system of the FIRE tokamak utilizes inertially cooled, copper alloy Bitter plate type magnets which are LN2 cooled between shots. The TF configuration is wedged and uses C17510 high strength, high conductivity beryllium copper alloy which was developed for BPX in the inner leg, where the stress is highest. In FY 01, a slightly larger design was adopted (R=2.14 m...

We have developed a method for the determination of copper in natural waters at nanomolar levels. The use of a microplate-reader minimizes sample processing time (~25 s per sample), reagent consumption (~120 μL per sample), and sample volume (~700 μL). Copper is detected by chemiluminescence. This technique is based on the formation of a complex between copper and 1,10-phenanthroline and the su...
