Recently a fingering morphology, resembling the hydrodynamic Saffman-Taylor instability, was identified in the quasi-two-dimensional electrodeposition of copper. We present here measurements of the dispersion relation of the growing front. The instability is accompanied by gravity-driven convection rolls at the electrodes, which are examined using particle image velocimetry. While at the anode ...
The sticking coefficient of nitrogen gas on a thick solid nitrogen film on a copper cold finger was studied at low temperature. For surface temperatures of about 12 K the sticking coefficient is measured to be 99.0 0.6%. Our result implies that it will be possible to make a intense and high brightness slow positron source starting from a small diameter deposit of the gaseous positron emitter N2...
HAL is a multi-disciplinary open access archive for the deposit and dissemination of scientific research documents, whether they are published or not. The documents may come from teaching and research institutions in France or abroad, or from public or private research centers. L’archive ouverte pluridisciplinaire HAL, est destinée au dépôt et à la diffusion de documents scientifiques de niveau...
Electrorefining is the process of choice to purify several metals, among which copper. A crucial parameter in electrorefining, and electroplating general, additive activity. Several additives are introduced electrolyte ensure a morphological smooth copper deposit. Thiourea but complex used it known degenerate both reaction product as thiourea itself can with ions. Unfortunately, time dependent ...
In the research described in this paper, studied was sorption capacity of natural and ferric modification of zeolite tuff containing mineral clinoptilolite from the Nižný Hrabovec deposit to remove potentially toxic metals (ionic forms of chromium, nickel, copper and aluminium) from their water solutions. We reported that the Fe (III) zeolite has an enhanced ability to sorption of Cu (II), and ...
greatly reduced the amount of the sample solution and the measuring time.1-3 However, the electronic osmometers reported to date are in use of flaccid mem branes which result in baseline instability and limit the use to low con centrations of colloid solute in solutions. Recently, we have designed an electronic osmometer with a rigid semiperme able membrane made from a baked clay disc permeated...
Entrepreneurship and competitiveness are inevitable for the dynamism and dynamism of the space in the age of globalization. This issue is very important in rural areas. Rural Entrepreneurship and competitiveness - Considering the importance of cities as the focal points of development and evolution of space in the era of globalization -are considered as an effective solution to prevent stagnat...
†Konan University, ‡Hyogo University of Teacher Education, *Japan Institute for Educational Measurement, Inc. We eating shshi (sushi)ski. I read a book. I play baseball everyday. And My brother play baseball to. “Becose, Let‘s play baseball in Japan.” School trip is very fun. “But, it’s very busy.” Becaes I like school trip.
