Abstract: Citations are a way to show how researchers build on existing research to further evolve research. The citation count is an indication of the influence of specific articles. The importance of citations means that it is valuable to analyze the articles that are cited the most. This research investigates highly-cited articles in physics (1979-2008) using citation data from the ISI Web of Science. In this study, 1544205 articles were examined. The objective of the analysis was to identify and list the highly-productive countries, institutions, authors, and fields in physics. Based on the analysis, it was found that the USA is the world leader in physics, and Japan has maintained the highest growth rate in physics research since 1990. Furthermore, the research focus at Bell Labs and IBM has played important roles in physics. A striking fact is that the five most active authors are all Japanese, but the five most active institutions are all in the USA. In fact, only The University of Tokyo is ranked among the top 11 institutions, and only American authors have single-author articles ranked among the top 19 articles. The highest-impact articles are distributed across 25 subjects categories. Physics, Multidisciplinary has 424 articles, and is ranked at No. 1 in total articles, followed by Physics, Condensed Matter. The study can provide science policy makers with a picture of innovation capability in this field and help them make better decisions. Hopefully, this study will stimulate useful discussion among scientists and research managers about future research directions.

Abstract: A new ionic sieve has been prepared in a process of saturating a substrate with Pb (Ac)₂ solution followed by thermodynamic recrystallization. The substrate is silica gel on which beta-type titanium is introduced. The ionic sieve possesses a specific selectivity for Pb(II) ions in the aqueous solution with multicomponent composition. The aquatic chemistry of Pb(II), the amphoteric surface of the ionic sieve and the behaviour of Pb(II) at the solid-liquid interface are discussed. The ionic sieve can be used to remove lead from various aquatic systems.

Abstract: A new iminodiacetic acid (IDA) type chelating membrane based on composite matrix formed by covalently coupling the polyglycidyl methacrylate to cotton cellulose fiber was developed. The study focused on the optimal conditions for the preparation of the membrane and the reaction of the chelating agent (iminodiacetic acid, IDA) with the matrix. The physical properties of the chelating membrane were tested by electron micrography and BET surface area instrument. The relationship between flow-rate and backpressure was almost linear. Adsorption isotherm of protein on Cu²⁺ - IDA membrane was determined by batch experiments. The dissociation constants and the maximum adsorption capacity were obtained. The results of affinity purification of human serum albumin and bovine liver catalase on membrane are comparable with those on gel chromatography presented in literature. The separations performed on the membrane chromatography, however, were 3-5 times faster than those on gel chromatography. The immobilized metal composite membrane was also successfully used in HPLC for rapid analysis of protein. Thus, the composite membrane reported here, with low backpressure, low cost and long service-life, is quite suitable for rapid and large scale affinity purification and HPLC analysis of biopolymers

Abstract: Hide collagen of animals is used to prepare adsorbent material and its adsorption properties to tannins are investigated. It is indicated that the collagen fibres has excellent adsorption selectivity and high adsorption capacity to tannins. The adsorption rate of tannins is more than 90% whilst less than 10% of functional components are retained by the adsorbent. The adsorption mechanism of tannins onto hide collagen fibres is hydrogen-bonding association. Freundlich model can be used to describe the adsorption isotherms, and the pseudo-second-order rate model can be used to describe adsorption kinetics.
